Answer 1

Therefore, we estimate that about 7 sixth graders should be chosen to create a representative sample, given that 9 seventh graders were chosen.

What is statistics?

Statistics is a branch of mathematics that involves the collection, analysis, interpretation, presentation, and organization of data. It provides methods for summarizing and describing data, making inferences about populations based on samples, and testing hypotheses. Statistics is used in many fields, such as business, economics, health care, social sciences, engineering, and more, to make decisions and draw conclusions based on data. Some common techniques used in statistics include descriptive statistics (e.g., mean, median, mode, standard deviation), probability theory, hypothesis testing, regression analysis, and sampling methods.

Here,

To estimate the number of sixth graders that should be chosen to create a representative sample, we can use the proportion of seventh graders in the sample and assume that the proportions of each grade in the sample should match the proportions in the population. We know that the sample contains 9 seventh graders, but we don't know the total size of the sample yet. We can use the following formula to estimate the sample size:

sample proportion = population proportion

where

sample proportion = number of seventh graders in the sample / total sample size

population proportion = number of seventh graders in the population / total population size

We can plug in the values we know:

9 / total sample size = 180 / (160 + 180 + 140)

Simplifying the right-hand side:

9 / total sample size = 0.4

Multiplying both sides by total sample size and simplifying:

total sample size = 9 / 0.4

total sample size ≈ 22.5

This means that the sample size should be about 22.5 students. Since we can't choose a fractional number of students, we should round up to the nearest whole number, giving a total sample size of 23 students.

To estimate the number of sixth graders in the sample, we can use the proportion of sixth graders in the population and assume that the proportion should be the same in the sample:

number of sixth graders in the sample / total sample size = 160 / (160 + 180 + 140)

Simplifying the right-hand side:

number of sixth graders in the sample / total sample size = 0.32

Multiplying both sides by total sample size and simplifying:

number of sixth graders in the sample = 0.32 * 23

number of sixth graders in the sample ≈ 7

At the local pet store, zebra fish cost $2.00 each and neon tetras cost $2.30 each. If Yumi bought 13 fish for a total cost of $27.50, not including tax, how many of each type of fish did she buy?​

Answers

If Yumi bought 13 fish for total then yumi bought 8 zebra fish and 5 neon tetras.

What is substitution?

Substitution is a mathematical operation that involves replacing a variable or expression in an equation, function, or formula with another variable, expression, or value.

According to question:

Let's assume Yumi bought x zebra fish and y neon tetras.

x + y = 13 (equation 1)

2x + 2.3y = 27.5 (equation 2)

Using equation 1, we can solve for one variable in terms of the other:

x = 13 - y

Then, change x in equation 2 to the following expression:

2(13 - y) + 2.3y = 27.5

Simplifying and solving for y:

26 - 2y + 2.3y = 27.5

0.3y = 1.5

y = 5

So Yumi bought 5 neon tetras. To find how many zebra fish she bought, we can substitute y = 5 into equation 1:

x + 5 = 13

x = 8

Therefore, Yumi bought 8 zebra fish and 5 neon tetras.

Which conic section is formed when a plane intersects the central axis of a double-napped cone at a 90° angle?

Answers

The conic section that formed when a plane intersects the central axis of a double-napped cone at a 90° angle is circle

When a plane intersects the central axis of a double-napped cone at a 90° angle, the resulting conic section is a circle.

To understand why this is the case, we can first consider the properties of a double-napped cone. A double-napped cone is formed by rotating a straight line, called the generatrix, around an axis that intersects the line at a fixed point, called the vertex. The resulting surface consists of two parts, each of which is a circular cone.

Now, let us imagine a plane that intersects the central axis of the double-napped cone at a 90° angle. Since the central axis of the cone is perpendicular to the base, the plane must intersect both cones at their widest point, which is also their center. At this point, the cone has a circular cross-section, which means that the plane intersects the cone in a circle.

near their community. Peter and his mother flew from
Charlton to Thornton to make a mail delivery. Then they

How many kilometers did Peter and his mother
travel in all?

Answers

The answer is 250 kilometers. Peter and his mother traveled a total distance of 250 kilometers on their mail delivery.

What is distance?

Distance is a numerical measurement of how far apart two objects or points are. It is a scalar quantity, meaning that it is only expressed as a magnitude, or numerical value, without any direction.

1 centimeter is equal to 0.01 kilometers, so 50 kilometers would be equal to 5,000 centimeters. The total distance between the four cities is 5,000 centimeters, which is equal to 50 kilometers.

Charltc to Thornton is 1,000 centimeters, Thornton to Avon is 1,500 centimeters, Avon to Ashton is 1,000 centimeters, and Ashton to Charltc is 1,500 centimeters. This gives us a total of 5,000 centimeters, or 50 kilometers.

This can be calculated by multiplying the total distance between the four cities (50 kilometers) by the number of times they traveled the route (5 times, since they flew from Charltc to Thornton, then to Avon, then to Ashton, and then back to Charltc). This gives us 250 kilometers, which is the answer to the question.

If a large bag of the same candy has 75 pieces, which of the 5 colors is likely to appear the most? justify your answer.

Answers

If a large bag of the same candy has 75 pieces, then the expected average for each color is 15 pieces.

Now, let's apply this concept to our candy problem. If the bag of candy has 75 pieces, we can assume that each color makes up approximately 1/5 or 20% of the total. That means each color should have an equal chance of appearing, with an expected average of 15 pieces per color (75 pieces divided by 5 colors).

However, this is only an expected average. In reality, there may be some variation in the number of pieces of each color that we actually find in the bag. This variation can be caused by a variety of factors, such as the manufacturing process, the mixing of different batches of candy, or even random chance.

To determine which color is likely to appear the most, we can look at the range of variation for each color. If the range of variation for a particular color is higher than the expected average of 15 pieces, then that color is more likely to appear more often than the others. On the other hand, if the range of variation is lower than the expected average, then that color is less likely to appear as often.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to study the properties and behavior of triangles, and is also widely used in fields such as engineering, physics, surveying, and navigation. The three main trigonometric functions are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively. These functions relate the ratios of the sides of a right triangle to the angles of the triangle.  Trigonometry also involves other concepts such as the Pythagorean theorem, which relates the sides of a right triangle, and the unit circle, which is a circle of radius 1 used to define trigonometric functions of angles beyond 90 degrees. Trigonometry is widely used in a variety of applications, such as calculating the heights of buildings and mountains, designing bridges and other structures, and predicting the motion of objects in physics and engineering.

Here,

In a right triangle, the tangent of an acute angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

Using this formula, we can find the tangent of angle G:

tan(G) = opposite / adjacent

tan(G) = 6 / 10

tan(G) = 0.6

To find the measure of angle G, we need to take the inverse tangent (or arctangent) of 0.6:

G = tan⁻¹(0.6)

Use Lagrange multiplier techniques to find shortest and longest distances from the origin to the curve x2 + xy + y2 = 3. shortest distance longest distance

Answers

The shortest distance from the origin to the curve x2 + xy + y2 = 3 is √(6-2√7) and the longest distance is √(6+2√7).

We have to find the shortest and longest distances from the origin to the curve x^2 + xy + y^2 = 3. This can be done using the Lagrange multiplier technique.

Given, x^2 + xy + y^2 = 3.

We have to minimize and maximize the distance of the origin from the given curve. The distance of the origin from the point (x, y) is given by √(x²+y²).

Therefore, we have to minimize and maximize the function f(x, y) = √(x²+y²) subject to the constraint x^2 + xy + y^2 = 3.

Now, we have to form the Lagrange function.

L(x, y, λ) = f(x, y) + λ(g(x, y))

where, g(x, y) = x2 + xy + y2 - 3L(x, y, λ) = √(x²+y²) + λ(x2 + xy + y2 - 3)

Now, we have to find the partial derivatives of L with respect to x, y, and λ.

∂L/∂x = x/√(x²+y²) + 2λx+y = 0 ............. (1)

∂L/∂y = y/√(x²+y²) + λx+2λy = 0 ............. (2)

∂L/∂λ = x² + xy + y² - 3 = 0 ............. (3)

Solving equations (1) and (2), we get x/√(x²+y²) = 2y/x.

Since x and y cannot be equal to 0 simultaneously, we can say that x/y = ±2.

Substituting x = ±2y in equation (3), we get y²(5±2√7) = 9.

Now, we can solve for x and y to get the values of (x, y) at which the minimum and maximum value of the distance of the origin occurs.

Using x = 2y, we get y²(5+2√7) = 9 ⇒ y = ±3/√(5+2√7)

Using x = -2y, we get y²(5-2√7) = 9 ⇒ y = ±3/√(5-2√7)

Therefore, the four points at which the distance is minimum and maximum are {(2/√(5+2√7), 1/√(5+2√7)), (-2/√(5+2√7), -1/√(5+2√7)), (2/√(5-2√7), -1/√(5-2√7)), (-2/√(5-2√7), 1/√(5-2√7))}.

To find the minimum and maximum distances, we can substitute these points in f(x, y) = √(x²+y²).

After substituting, we get the minimum distance as √(6-2√7) and the maximum distance as √(6+2√7).

Therefore, the shortest distance from the origin to the curve x^2 + xy + y^2 = 3 is √(6-2√7) and the longest distance is √(6+2√7).

Answers

After using permutations and combination, There are 1001 groups of 4 people that can answer the 4 different phone lines if all the lines begin to ring at once.

To determine the number of groups of 4 people that can answer the 4 different phone lines, we can use the combination formula, which is:

nCr = n! / (r! * (n-r)!)

where n is the total number of people in the office and r is the number of people needed to answer each phone line.

In this case, n = 14 (the total number of people in the office) and r = 4 (the number of people needed to answer each phone line).

So, the number of groups of 4 people that can answer the 4 different phone lines is:

¹⁴C₄ = 14! / (4! * (14-4)!) = 1001

The probability of drawing three cards with replacement from a standard deck of 52 cards is 1/416.

The probability of drawing three cards with replacement from a standard deck of 52 cards is to be found when the first card is a club, the second card is a red card, and the third card is the six of hearts.

Here, the Probability of the first card being a club = P(C) = 13/52 = 1/4 [Since there are 13 clubs in the deck of 52 cards]

Probability of the second card being a red card = P(Red) = 26/52 = 1/2 [Since there are 26 red cards in the deck of 52 cards]

Probability of the third card being six of hearts = P(6 of hearts) = 1/52 [Since there is only one six of hearts in the deck of 52 cards]

Therefore, the Probability of drawing three cards with replacement from a standard deck of 52 cards is

Find the Volume of the given cylinder. Round your answer to the nearest tenth. 3 m 3 m​

Answers

Answer: The volume of the cylinder is approximately 21.2 cubic meters

Step-by-step explanation:

To find the volume of a cylinder, we use the formula:

V = πr^2h

where:

V = volume

r = radius

h = height

In this case, we are given that the cylinder has a height of 3m, but we need to determine the radius.

Since we are not given the radius directly, we can estimate it from the diameter. If the cylinder has a diameter of 3m, then the radius would be half of that, or 1.5m.

So, substituting the values into the formula, we get:

V = π(1.5)^2(3)

V ≈ 21.2 m^3

Rounding to the nearest tenth, the volume of the cylinder is approximately 21.2 cubic meters.

The total cost of producing x pitchers is 5x.

Therefore, Profit [tex]= xp - 5x[/tex]

Profit can be expressed as a function of x using the formulae of the function,

[tex]y = xp - 5x= (p - 5)x[/tex] .............(1)

Now, the number of pitchers that she should produce and the price that she should charge in order to maximize profit can be found by finding the maximum value of the profit function (1).

Let the maximum profit be P. Maximize P with respect to x. To find the maximum of a function of x, we can find its derivative and equate it to zero.

[tex]dP/dx = 0P = (p - 5)x[/tex]

Differentiate P with respect to x again to determine whether it is a maximum or minimum.

[tex]d^2P/dx^2 = -5 < 0[/tex]

Since [tex]d^2P/dx^2[/tex] is negative, the value of P is a maximum.

Substitute the value of x from equation (1) in terms of P to find

[tex]p.P = (p - 5)*P/(p - 5) \\\\p = 5[/tex]

Therefore, the price to maximize profit is $5 and the number of pitchers to produce is,

[tex]x = P/(p - 5) = P/0 =[/tex] undefined

Maximum profit is [tex]P = (p - 5)x = (5 - 5)x = $0[/tex]

What is a lοgarithm?

A lοgarithm is a mathematical functiοn that represents the expοnent tο which a given base must be raised tο prοduce a certain value. In οther wοrds, it is a way οf expressing a number in terms οf the pοwer tο which anοther fixed number, called the base, must be raised tο prοduce that number.

Using the pοwer rule οf lοgarithms, we can simplify the lοgarithms inside the expressiοn as fοllοws:

3lοg5² - 2lοg5³ [tex]= log5^{(23)} - log5^{(32)}[/tex]

Using the quοtient rule οf lοgarithms, we can cοmbine the lοgarithms as fοllοws:

[tex]log5^{(23)} - log5^{(32)} = log(5^{(23) / 5^(32)})[/tex]

Simplifying the expressiοn inside the lοgarithm:

[tex]log(5^{(23)}/ 5^{(32)}) = log(5^6 / 5^6) = log(1) = 0[/tex]

Therefοre, [tex]3\log5^2[/tex] - [tex]2\log5^3[/tex] simplifies tο 0.

the chance of a blizzard tommorrow is 5%. write the complement of this event

Answers

Answer:

the chance of a blizzard tommorrow is 5%. write the complement of this event

Step-by-step explanation:

The complement of an event is the event that it does not happen, so the complement of a blizzard occurring tomorrow with a 5% chance is that a blizzard does not occur tomorrow with a probability of:

100% - 5% = 95%

Therefore, the complement event is that there is a 95% chance that a blizzard does not occur tomorrow.
