Answers

Answer 1

The probability that the ball transferred was red, given that a red ball was drawn from urn B, is 21/55, or about 0.382.

What is probability ?
Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 means that the event is impossible, and 1 means that the event is certain to happen.

To calculate probability, we usually take the number of favorable outcomes and divide it by the total number of possible outcomes. For example, if we flip a coin, the probability of getting heads is 1/2 because there is only one favorable outcome (heads) out of two possible outcomes (heads or tails).

According to the question:
Let's use Bayes' theorem to find the probability that the ball transferred was red:

Let R be the event that a red ball is drawn from urn B, and T be the event that the transferred ball was red.

Then we want to find P(T = red | R = red).

By Bayes' theorem, we have:

P(T = red | R = red) = P(R = red | T = red) * P(T = red) / P(R = red)

We can calculate each of these probabilities as follows:

P(R = red | T = red): The probability of drawing a red ball from urn B, given that a red ball was transferred from urn A to urn B, is 1/4, since urn B originally contained 1 red ball out of 7 total balls (3 black, 3 white, and 1 red) and we added one more red ball to it.

P(T = red): The probability that a red ball was transferred from urn A to urn B is 3/10, since urn A originally contained 3 red balls out of 10 total balls and we transferred one ball at random.

P(R = red): The overall probability of drawing a red ball from urn B is:

P(R = red) = P(R = red | T = black) * P(T = black) + P(R = red | T = red) * P(T = red)

where T = black means that a black ball was transferred from urn A to urn B. We can calculate each of these conditional probabilities as follows:

P(R = red | T = black): The probability of drawing a red ball from urn B, given that a black ball was transferred from urn A to urn B, is 1/7, since urn B originally contained 1 red ball out of 7 total balls (3 black, 3 white, and 1 red) and we did not add any more red balls to it.

P(T = black): The probability that a black ball was transferred from urn A to urn B is 4/10, since urn A originally contained 4 black balls out of 10 total balls and we transferred one ball at random.

Therefore, we have:

P(R = red) = 1/7 * 4/10 + 1/4 * 3/10 = 1/35 + 3/40 = 11/140

Putting it all together:

P(T = red | R = red) = (1/4) * (3/10) / (11/140) = 21/55

So the probability that the ball transferred was red, given that a red ball was drawn from urn B, is 21/55, or about 0.382.

A manufacturer knows that their items have a normally distributed length, with a mean of 5 inches, and standard deviation of 0.5 inches.

If one item is chosen at random, what is the probability that it is less than 4.6 inches long?

Answers

Answer:

Step-by-step explanation:

To solve this problem, we will use the properties of the normal distribution and standardize the given value using the formula:

z = (x - μ) / σ

where:

x = 4.6 inches (the given value)

μ = 5 inches (the mean)

σ = 0.5 inches (the standard deviation)

So we have:

z = (4.6 - 5) / 0.5

z = -0.8

Now we need to find the probability that the standardized value is less than -0.8. We can use a standard normal distribution table or a calculator to find this probability.

Using a standard normal distribution table, we can look up the probability for z = -0.8, which is 0.2119.

Therefore, the probability that a randomly chosen item is less than 4.6 inches long is 0.2119 or approximately 21.19%.

The pulse rate of the male population is known to be normal, with a mean of 73 BPM and a standard deviation of 11.3. Find the sample size necessary to be within 2 BPM of the population mean with 95% confidence.

Answers

Answer:

sample size of n=33

Step by step explanation:

We can use the formula for the margin of error for a confidence interval:

Margin of error = z* (sigma / sqrt(n))

Where z* is the z-score corresponding to the desired confidence level, sigma is the population standard deviation, and n is the sample size.

In this case, we want to find the sample size n such that the margin of error is no more than 2 BPM with 95% confidence. Since the sample size is unknown, we can use a t-distribution instead of the standard normal distribution to find the appropriate critical value.

The critical value for a 95% confidence interval with n-1 degrees of freedom is t=2.064 (from a t-distribution table).

Plugging in the known values, we have:

2 = 2.064 * (11.3 / sqrt(n))

Solving for n, we get:

n = (2.064 * 11.3 / 2)^2 = 32.59

Rounding up to the nearest whole number, we need a sample size of n=33 to be within 2 BPM of the population mean with 95% confidence.

In response to the stated question, we may state that According to the inequality facts provided, the only choice that must be true is B, because g must be bigger than 1.5. As a result, the solution is: B. g > 1.5

What is inequality?

In mathematics, an inequality is a non-equal connection between two expressions or values. As a result, imbalance leads to inequity. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two values are not equal, the not equal symbol is typically used (). Various disparities, no matter how little or huge, are utilised to contrast values. Many basic inequalities may be solved by altering the two sides until just the variables remain. Yet, a lot of factors contribute to inequality: Negative values are split or added on both sides. Exchange left and right.

We know that h > 3 and h - 2g = 0.

When we plug h = 2g into the first inequality, we get:

2g > 3

g > 1.5

As a result, we know that g must be bigger than 1.5, ruling out alternatives C and D.

Option A is not certainly true since we don't know if the value of g is bigger than 2.5.

Option E is also not certainly true, because we only know that g is more than 1.5, but not if it is bigger than 2.

Question about equations, please help!

Answers

Answer:

(a) y = 0.80x + 50

(b) Plugging x = 5 into the equation from part (a), we get y = 0.80(5) + 50 = 54, so the ordered pair associated with x = 5 is (5, 54). This means that if the car is driven for 5 miles, the total charge to the renter is $54.

(c) Let y be the total charge and solve for x:

y = 0.80x + 50

187.60 = 0.80x + 50

137.60 = 0.80x

x ≈ 172

Therefore, the car must have been driven approximately 172 miles

Answer:

(a) y = 0.8x + 50

(b)  D. The ordered pair associated with the equation x = 5 is (5, 54) and it means that the charge for driving the car for 5 miles is $54.

(c) If the renter paid $187.60, the car must have been driven for 172 miles.

Step-by-step explanation:

Part (a)

In the given problem, we are told that the rental car costs a flat fee of $50 plus an additional charge of $0.80 per mile driven.

Let x be the number of miles driven.

Let y be the total charge to the renter (in dollars).

We know that the total charge y will depend on the number of miles driven x, and we can express this relationship using a linear equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the value of y when x = 0).

In this case, we know that the cost per mile is $0.80 so the slope of the line is m = 0.8, and the flat fee is $50 so the y-intercept is b = 50.

Substitute these values into the equation to get:

[tex]y = 0.8x + 50[/tex]

[tex]\hrulefill[/tex]

Part (b)

To find the ordered pair associated with x = 5, substitute x = 5 into the equation:

[tex]\begin{aligned}x=5\implies y &= 0.8(5) + 50\\&=4+54\\&=54\end{aligned}[/tex]

The ordered pair associated with the equation x = 5 is (5, 54) and it means that the charge for driving the car for 5 miles is $54.

[tex]\hrulefill[/tex]

Part (c)

To find how many miles the car was driven if the renter paid $187.60, set y = 187.60 and solve for x:

[tex]\begin{aligned}\implies 0.8x + 50&=187.60\\0.8x + 50-50&=187.60-50\\0.8x&=137.60\\\dfrac{0.8x}{0.8}&=\dfrac{137.60}{0.8}\\x &= 172\end{aligned}[/tex]

Therefore, if the renter paid $187.60, the car must have been driven for 172 miles.

Explain about the transversal?

A line that cuts over two parallel lines is referred to as a transversal line.

Each pair of internal angles located on the exact side of a transversal that meets two parallel lines is supplementary, or they add up to 180°.

The opposing angles created by the junction of two lines are known as vertical angles but rather vertically opposite angles.

m(∠AGH ) = m(∠BDG ) (corresponding angles)

3x +  2 = 2x + 32

x = 30

m(∠AGH ) = 3(30) +  2 = 92

m(∠BDG ) = 2(30) + 32 = 92

m(∠DGF ) = m(∠AGH ) = 92 (vertically opposite angles)

m(∠HGF ) = 180 - m(∠AGH ) = 180 - 92 = 88 (linear pair).

m(∠AGD ) = m(∠HGF ) = 88 (vertically opposite angles)

m(∠BDG ) = 92 (calculated earlier)

m(∠BDC ) = m(∠AGD ) =  88 (corresponding angles)

If F1 = 4y - 6, F2 = 9y + 3 and F3 = -y - 8, simplify F1 × F2 - F3 in terms of y.

Answers

Answer:

To simplify F1 × F2 - F3 in terms of y, we need to first find the product of F1 and F2, and then subtract F3.

F1 × F2 can be expanded using the distributive property:

F1 × F2 = (4y - 6) × (9y + 3) = 4y × 9y + 4y × 3 - 6 × 9y - 6 × 3

= 36y^2 + 12y - 54y - 18

= 36y^2 - 42y - 18

Now we can subtract F3 from the result:

F1 × F2 - F3 = (36y^2 - 42y - 18) - (-y - 8)

= 36y^2 - 42y - 18 + y + 8

= 36y^2 - 41y - 10

Therefore, F1 × F2 - F3 in terms of y is 36y^2 - 41y - 10.

A person invests 5500 dollars in a bank. The bank pays 4.5% interest compounded
annually. To the nearest tenth of a year, how long must the person leave the money
in the bank until it reaches 6700 dollars?

Answers

Answer:

Step-by-step explanation:

We can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the final amount, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years).

In this case, we know that P = $5500, r = 4.5% = 0.045, and we want to find t when A = $6700. We also know that the interest is compounded annually, so n = 1.

Substituting these values into the formula, we get:

$6700 = $5500(1 + 0.045/1)^(1t)

Dividing both sides by $5500, we get:

1.218181818 = (1.045)^t

Taking the natural logarithm of both sides, we get:

ln(1.218181818) = ln(1.045)^t

Using the property of logarithms that ln(a^b) = b ln(a), we can rewrite the right side as:

ln(1.218181818) = t ln(1.045)

Dividing both sides by ln(1.045), we get:

t = ln(1.218181818)/ln(1.045) ≈ 4.2

Therefore, the person must leave the money in the bank for about 4.2 years to reach $6700. To the nearest tenth of a year, the answer is 4.2 years.

4 x 1 1/5= multiply. Write the product as a mixed number.

Answers

Answer:

4 4/5.

Step by step explanation:

To multiply 4 by 1 1/5, we can first convert the mixed number 1 1/5 to an improper fraction:

1 1/5 = 6/5

Now we can multiply 4 by 6/5:

4 x 6/5 = 24/5

To write the product as a mixed number, we need to express 24/5 as a whole number plus a proper fraction. We can do this by dividing 24 by 5:

24 ÷ 5 = 4 with a remainder of 4

So, 24/5 can be written as 4 4/5. Therefore, the product of 4 and 1 1/5 is:

4 x 1 1/5 = 4 4/5.

1 inch / 170 feet = x inches / 850 feet

In the scale drawing, x represents the height of the building in inches.

To find x, we can cross-multiply and simplify:

1 inch * 850 feet = 170 feet * x inches

850 inches = 170 feet * x

In response to the stated question, we may state that As a result, the overall probability of an accurately picked drive-thru order across all chains is roughly 0.929, or 92.9%.

What is probability?

Probability theory is an area of mathematics that calculates the likelihood of an occurrence or a proposition being true. A risk is a number in the range of 0 and 1, whereas 1 implies certainty and a probability of roughly 0 indicates how likely an event seems to be to occur. Probability is a mathematical expression of the chance or chances that a given event will occur. Probabilities can alternatively be stated as integers between 0 and 1 or as % from 0% to 100%. the ratio of occurrences among equally likely choices that result in a certain event in comparison to all other outcomes.

Using the data in the table, we can compute the likelihood of a correct drive-thru order for each fast food chain, as well as the overall chance of an accurate order across all chains.

Divide the number of accurate orders by the total number of orders to find the chance of a randomly picked order being accurate at each chain:

P(accurate order) = 1246 / 1300 = 0.958 for McDonald's

P(accurate order) = 1020 / 1100 = 0.927 Taco Bell

P(accurate order) = 708 / 800 = 0.885 for Burger King

P(accurate order) = 940 / 1000 = 0.94 for Wendy's

P(adequate overall order) = 0.3 * 0.958 + 0.25 * 0.927 + 0.2 * 0.885 + 0.25 * 0.94 = 0.929

What is co-ordinate geometry ?

Coordinate geometry, also known as analytic geometry, is a branch of mathematics that deals with the study of geometric shapes using algebraic principles. It involves the use of coordinates to represent points, lines, curves, and other geometric figures on a plane or in space.

According to the given information:

we need to know the coordinates of its foci, co-vertices, and the center. We can start by finding the center of the ellipse, which is the midpoint of the line segment joining the foci:

Center = ( (-8 + (-8))/2 , (14 + (-16))/2 ) = (-8,-1)

Next, we can find the distance between the foci, which is given by:

[tex]distance between foci = 2c = sqrt[(14 - (-16))^2 + (-8 - (-8))^2] = 30[/tex]

where c is the distance from the center to either focus.

We also know that the distance between the co-vertices is given by:

distance between co-vertices = 2a = |-16 - 0| = 16

where a is the distance from the center to either co-vertex.

Finally, we can use the standard form equation for an ellipse centered at the origin:

[tex](x^2/a^2) + (y^2/b^2) = 1[/tex]

where b is the distance from the center to either vertex.

To find b, we can use the Pythagorean theorem:

[tex]b^2 = c^2 - a^2 \\b^2 = 30^2 - 16^2\\b^2 = 784\\b = 28[/tex]

Now we have all the information we need to write the equation of the ellipse:

[tex](x+8)^2/16^2 + (y+1)^2/28^2 = 1[/tex]

Using a standard normal distribution table, we can look up the value that corresponds to an area of 0.67 to the left of the mean, which is 0.44. This means that P(Z ≤ 0.44) = 0.67, where Z is the standard normal random variable.

Next, we can use the formula for standardizing a normal random variable to convert this z-score to the corresponding temperature on the thermometer scale:

z = (x - μ) / σ

where μ is the mean, σ is the standard deviation, and x is the temperature we want to find.

Rearranging this formula, we get:

x = μ + z * σ

Plugging in the values, we get:

x = 0 + 0.44 * 1.00

x = 0.44

Therefore, the temperature corresponding to the 67th percentile is 0.44°C.

I need someone to help me find the h of the parallelogram.

Answers

The value of height (h)  will be 6 cm.

What is Parallelogram?

A parallelogram is a four-sided polygon in which both pairs of opposite sides are parallel and equal in length. It is a special case of a quadrilateral, which means a polygon with four sides. The opposite angles in a parallelogram are also equal in measure, and the adjacent angles are supplementary, which means they add up to 180 degrees.

Given : height (H) = 5 cm

            base (B) = 12 cm

Similarly, height (h) = 5 cm

               base (h) = 12 cm

Now, we know that area of parallelogram will be same whether we use different method.

So, area of given parallelogram  =  base × height

                                         B × H    =  b × h

                                        12 × 5    =  10 × h

                                            60     =  10 h

So,   h = 60/10 = 6 cm.

FILL IN THE BLANK the probability of one event given the known outcome of a (possibly) related event is known as __probability.

Answers

The probability of one event given the known outcome of a (possibly) related event is known as conditional probability.

Conditional probability is the measure of the probability of an event occurring given that the another event will already occurred. It is denoted by P(A | B), which represents the probability of event A given that event B has occurred. The conditional probability of A given B can be calculated using the formula:

P(A | B)=P(A and B)/P(B)

where P(A and B) represents the probability of both events A and B occurring, and P(B) represents the probability of event B occurring.

For example, consider a deck of 52 playing cards. The probability of drawing a king from the deck is 4/52, or 1/13. If one card is drawn from the deck and it is revealed to be a heart, then the probability of drawing a king from the remaining cards in the deck that are not hearts is:

P(king | heart) = P(king and heart) / P(heart)

P(king and heart) = 1/52 (there is only one king of hearts in the deck)

P(heart) = 13/52 (there are 13 hearts in the deck)

P(king | heart) = (1/52) / (13/52) = 1/13

given the following two point find the the length distance of ab round your asnwer to the nearrest tenth (-4,-6) and b (3,2)

Answers

The length distance of ab between the points  (-4,-6) and b (3,2) is   10.6 units.

Now to find the distance between points A(-4,6) and B(3,2), we  can use the distance formula which is :

d = sqrt((x₂ - x₁)² + (y₂ - y₁)²), where (x₁,y₁)=(-4,-6) and (x₂,y₂)=(3,2), now we substituting the  values into the formula  after which we get :

d = sqrt((3 - (-4))² + (2 - (-6))²) = sqrt((7)² + (8)²) = sqrt(49 + 64) = sqrt(113) ≈ 10.6

it comes out  that the distance between points A and B is approximately 10.6  units  which are rounded to the nearest tenth.

You are playing a game with a friend. It costs you $2 to play. If you roll a 1 on a 6-sided die you win $4. If you roll a 2, 3, 4, 5, or 6 you win nothing and lose $2 the cost to play. Calculate the expected value for this game. How much should the player be willing to to pay to play this game and not lose money in the long run?

Answers

The player should be willing to pay up to $12 to play this game and not lose money in the long run.

How to calculate the expected value for this game.

First we need to multiply the probability of winning by the amount won and subtract the probability of losing by the amount lost.

The probability of rolling a 1 on a 6-sided die is 1/6, and the probability of rolling any other number is 5/6.

So, the expected value of the game is:

(1/6) x $4 - (5/6) x $2

= ($4/6) - ($10/6)

= -$1/3

This means that on average, for every game played, the player can expect to lose $1/3.

To find out how much the player should be willing to pay to play this game and not lose money in the long run, we can set the expected value equal to zero:

(1/6) x $4 - (5/6) x $2 = $0

Simplifying the equation, we get:

$4/6 = $10/6

Multiplying both sides by x, we get:

(1/6) x - $2 = 0

Solving for x, we get:

x = $12

Therefore, the player should be willing to pay up to $12 to play this game and not lose money in the long run.

By finding the derivative and evaluating it in x = -2, we will see that the slope is 12.

How to find the slope of the function at the given point?

To find the slope of the tangent line at a given point, we need to take the derivative and evaluate it in the x-value of the given point.

Here we have the function:

f(x) = 3x² + 7

If we differentiate it with respect to x, we will get:

f'(x) = 2·3x

f'(x) = 6x

That is the derivative, now we want to find the slope at (-2, 19), to find the slope at that point we need to get:

f'(-2) = 6·-2

f'(-2) = -12

That is the slope of the graph.

Express using algebra:
Z increased by 16%

Answers

Answer:

Let's start by expressing "Z increased by 16%" using algebra.

Let Z be the original value of some quantity.

To increase Z by 16%, we need to add 16% of Z to Z:

Z + 0.16Z

Simplifying this expression by factoring out Z, we get:

Z(1 + 0.16)

Combining like terms, we have:

Z(1.16)

Therefore, "Z increased by 16%" can be expressed algebraically as:

Z increased by 16% = Z(1.16)
