3p^2 +7p=0 solve by factoring

Answers

Answer:

p = 0, p = -7/3

Step-by-step explanation:

Pre-Solving

We are given the following equation:
3p² + 7p = 0

We want to solve the equation by factoring.

Solving

To factor, we want to look for a common term that we can pull out.

You may notice that both terms have 'p' in common, so we can pull out p from both terms.

This will then make the equation:

p(3p + 7) = 0

Now, we can use zero product property to solve the equation.

p = 0

3p + 7 = 0

Subtract.

3p = -7

Divide.

p = -7/3

Our answers are p = 0 and p = -7/3

Wilson was 42 inches tall on Jan 1, 2000, and 51 inches tall on Jan 1, 2002. William was 5 feet tall on Jan 1, 2000, and 6 feet tall on Jan 1, 2002.
Conclusion: The difference between 42 and 51 is greater than the difference between 5 and 6, so Wilson grew more during one year.

Answers

Wilson and William were measured at various times, therefore drawing the inference that Wilson grew more over the course of a year than William is incorrect and the statistics is misleading.

What is descriptive statistics?

Inferential statistics and descriptive statistics are two disciplines of statistics with distinct applications.

Summarizing and characterizing gathered data is the focus of descriptive statistics. It uses techniques including graphical presentations, measurements of variability, and measures of central tendency, such as mean, median, and mode (e.g., histograms, box plots). The purpose of descriptive statistics is to shed light on a sample's or population's properties, such as its distribution, dispersion, and shape.

Assume there are 4 collector cards with one card inside every box of cereal you buy. Each card has a probability of 1/4 of being inside your box. What's the probability you get the complete set of cards on Box 5? Go from left to right as in accordance to time. 4.3 2 3/ 6 mar

Answers

The probability of getting the complete set of cards in Box 5 is 3/64.

To calculate the probability of getting the complete set of cards in Box 5, we have to consider the probability of getting each of the 4 cards in the previous 4 boxes.

For the first box,

The probability of getting any one of the 4 cards is 1,

since there are no previous boxes to consider.

For the second box,

The probability of getting a card that is not already in our possession is 3/4 (since there is one card already collected).

For the third box,

The probability of getting a card that is not already in our possession is 2/4 (since there are now two cards already collected).

For the fourth box,

The probability of getting a card that is not already in our possession is 1/4 (since there are now three cards already collected).

Multiplying these probabilities together, we get,

⇒ 1 x 3/4 x 2/4 x 1/4 = 3/64

So the probability of getting the complete set of cards in Box 5 is 3/64.

Answer:

Zeros: x = -10 and x = -3

Vertex: [tex](-\frac{13}{2} , \frac{49}{4} )[/tex]

Step-by-step explanation:

Pre-Solving

We are given the following function:
f(x) = -(x+3)(x+10)

We want to find the zeros and the vertex of the parabola.

SolvingZeros

The zeros are the values of the function where f(x) = 0.

So, in order to find the zeros, we can set f(x) = 0.

0 = -(x+3)(x+10)

We can divide both sides by -1, to get:

0 = (x+3)(x+10)

To solve this, we will use zero product property.
Split and solve:

x+3 = 0

x = -3


x+10=0

x = -10

Vertex

Now, to find the vertex, we first get the average of the zeros.

Add the values of the zeros together, then divide by two:

[tex]\frac{-3-10}{2}[/tex] = [tex]\frac{-13}{2}[/tex]

Now, we plug this in for x to get the y value (found through f(x)) of the vertex.

[tex]f(-\frac{13}{2}) = -(-\frac{13}{2} + 3) (-\frac{13}{2} + 10)[/tex] = [tex]\frac{49}{9}[/tex]

So, the vertex is [tex](-\frac{13}{2} , \frac{49}{4} )[/tex]

There are 30 students in Mr. Hall class. 1/3 of the students are traveling somewhere this summer. Of those traveling, 1/5 are going out of the country. How many students are traveling out of the country?

Answers

The number of students traveling are 2 students out of the 30 who are traveling out of the country this summer.  If 1/3 of the students are traveling somewhere this summer, then we can calculate the number of students who are traveling by multiplying the total number of students by 1/3:

Number of students traveling = 30 x 1/3 = 10  

Now, we need to find out how many of these 10 students are traveling out of the country. We know that 1/5 of the students who are traveling are going out of the country, so we can find the number of students who are traveling out of the country by multiplying the total number of traveling students by 1/5:

Number of students traveling out of the country = 10 x 1/5 = 2

Therefore, there are 2 students out of the 30 who are traveling out of the country this summer.

It's important to note that fractions can be converted to decimals or percentages to make them easier to work with. For example, 1/3 can be written as 0.33 or 33%, and 1/5 can be written as 0.20 or 20%. This can be particularly useful when dealing with more complex problems or when working with larger numbers.

In summary, by using the information given, we can determine that out of the 30 students in Mr. Hall's class, 10 are traveling somewhere this summer, and out of those 10 students, 2 are going out of the country. This type of problem-solving helps build math skills that are applicable in real-world scenarios, such as budgeting and planning for travel.

What is the missing side on a rectangle 8 8 3 12

Answers

The missing side of the rectangle is 21.

In a rectangle, opposite sides are congruent and parallel. Therefore, if we know the length and width of a rectangle, we can find the length of any missing side using the formula for the area or the perimeter of a rectangle.

In the given rectangle 8 8 3 12, the two sides are labeled 8 and 12, which represent the length and the width of the rectangle, respectively. To find the missing side, we can use the formula for the perimeter of a rectangle, which is:

Perimeter = 2 x (length + width)

Substituting the given values, we get:

Perimeter = 2 x (8 + 12)

Perimeter = 2 x 20

Perimeter = 40

Since we have the length and width of the rectangle, we can use the perimeter formula to solve for the missing side. We know that the perimeter is equal to the sum of all four sides of the rectangle, so we can write:

Perimeter = 8 + 8 + 3 + x

where x is the missing side.

Substituting the value of the perimeter (40) and simplifying, we get:

40 = 19 + x

x = 21

Suppose we create a box model for the outcome of a game of darts. The player has a 1/3 chance of throwing a dart in the inner ring, and a 2/3 chance of the dart landing in the outer ring. In our model, we have two unique tickets marked "inner" and "outer." We put in 1 ticket marked "inner." How many tickets do we put in that are marked "outer?"
a. 0
b. 1
c. 2
d. 3

Answers

As per the combination method, the number of tickets that we put in that are marked "outer" is 3 (option d).

In this case, we want to choose the number of tickets marked "outer." Let's call this number k. We know that we already put one ticket marked "inner" in the box, so the total number of tickets in the box is 2. Therefore, n = 2.

Now we need to determine k. We want to know how many tickets we need to put in that are marked "outer." We can represent this as a. So we have:

ᵃC₁ = a! / ((1!)(a-1)!) = a

We want to find the value of a that satisfies the condition that the probability of choosing an "inner" ticket is 1/3 and the probability of choosing an "outer" ticket is 3/2.

Since we already put in 1 ticket marked "inner," the probability of choosing an "inner" ticket is 1/2, which means the probability of choosing an "outer" ticket is also 1/2.

We know that the probability of choosing an "outer" ticket is 3/2, so we can set up the following equation:

ᵃC₁ / 2 = 3/2

Solving for a, we get:

a = 3

In conclusion, the answer is (d) 3.

a machine that manufactures automobile parts produces defective parts of the time. if parts produced by this machine are randomly selected, what is the probability that at most of the parts are defective? carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (if necessary, consult a list of formulas.)

Answers

The probability that at most of the parts are defective is 0.96.

A machine that manufactures automobile parts produces defective parts of the time. If parts produced by this machine are randomly selected, what is the probability that at most of the parts are defective?

The given probability of producing defective parts is P(defective) = 0.15. Now, we need to find the probability that at most of the parts are defective. This can be done by finding the probability of producing 0, 1, or 2 defective parts.

Let X denotes the number of defective parts. So, we have to calculate the probabilities for P(X = 0), P(X = 1), and P(X = 2). To calculate these probabilities, we will use the binomial probability formula:

P(X = x) ={n}C{x} p^x (1 - p)^{n - x}, Here, n = number of parts produced, p = probability of producing defective parts

x = number of defective parts

First, we need to find P(X = 0),

P(X = 0) = (0.85)^5 = 0.4437

P(X = 1) = {5}C{1} (0.15)^1 (0.85)^4 = 0.3672

P(X = 2) = {5}C{2} (0.15)^2 (0.85)^3 = 0.1459

Now, we can find the probability that at most of the parts are defective as follows:

P{at most 2 defective parts}) = P(X = 0) + P(X = 1) + P(X = 2) = 0.957

Therefore, the probability that at most of the parts are defective is 0.96.

1. We know that sides AB and CD of trapezoid ABCD are parallel. We can use the tangent function to find the length of side AD because angle B is a right angle and angle ABD is 45 degrees:

AD/AB = tan(45)

AD=AB * tan(45) AD=AB

As a result, AD = 10.

2. We know that the sides PQ and RS of the trapezoid PQRS are parallel. We can use the sine function to find the length of side PS because angle Q is a right angle and angle PSQ is 60 degrees:

PS/QS sin(60) =

PS = sin * QS (60)

5 * sqrt = PS (3)

As a result, PS = 5*sqrt (3).

3. We know that the sides UV and WX of a trapezoid UVWX are parallel. We can use the cosine function to find the length of side WU because angle V is a right angle and angle WVU is 30 degrees:

WU/UV cos(30) =

UV * cos WU (30)

5 * sqrt(3) / 2 = WU

As a result, WU = (5/2)*sqrt (3).

4. We know that the sides LM and NO of the trapezoid LMNO are parallel. We can use the sine function to find the length of side MO because angle L is a right angle and angle MNO is 30 degrees:

MO/NO sin(30) =

MO = 4 / 2 MO = NO * sin(30)

As a result, MO = 2.

Because angles MNO and LMO add up to 180 degrees, we can calculate angle LMO as follows:

LMO angle = 180 - angle LMO MNO angle = 150 degrees

Finally, because angle N is a right angle, we can calculate angle L as follows:

angle L = angle - 180 LMO stands for angle. MNO\sangle L = 180 - 150 - 30 degree angle L = 0

As a result, angle L is 0 degrees.

The condition that must be true in order for a confidence interval based on de Moivre's equation to be valid is:

d. The underlying distribution of the data must be normally distributed.

What is a confidence interval?

A confidence interval is an interval estimate of a population parameter that specifies a range of values within which the parameter is likely to lie with a certain level of confidence. In other words, it represents the degree of uncertainty associated with the estimate.

De Moivre's equation

De Moivre's equation is a formula for approximating the probability of a specific number of successes in a series of independent Bernoulli trials. This formula is only relevant if the sample size is large enough such that the normal approximation to the binomial distribution is valid. Thus, this formula can be used to calculate confidence intervals for binomial proportions when the sample size is large enough to apply the normal approximation.

Let d be a positive integer. Show that among any group of d+1 (not necessarily consecutive) integers there are two with exactly the same remainder when they are divided by d. HINT: Use the Pigeon-hole Principle!

Answers

The Pigeon-hole Principle states that if there are more pigeons than pigeonholes, then at least one pigeonhole must contain more than one pigeon. This proves that among any group of d+1 integers there are two with exactly the same remainder when divided by d.

This concept can be applied to your question: If there are d+1 integers, and we divide each of them by d, there are at most d remainders that can be obtained. This means that two of the integers must have the same remainder when divided by d.
To prove this, let us assume that all d+1 integers have different remainders when divided by d. Then the remainders must range from 0 to d-1. For example, if d=5, then the remainders must be 0, 1, 2, 3 and 4. Let us denote the integers by x0, x1, x2, ... , xd. Now we can apply the Pigeon-hole Principle. We have d+1 pigeons (x0, x1, x2, ... , xd) and d pigeonholes (remainders 0, 1, 2, 3, 4). Since d+1 is greater than d, at least one pigeonhole must contain more than one pigeon. This means that two of the integers must have the same remainder when divided by d.

how do you use TAN in equations and what is it?

Answers

Answer:

TAN is a mathematical function in trigonometry that stands for tangent. It is used to calculate the tangent of an angle in a right triangle, which is defined as the ratio of the length of the opposite side to the length of the adjacent side.

In equations, you can use TAN to find the value of the tangent of an angle. For example, if you have an angle of 30 degrees in a right triangle and you want to find the value of the tangent of that angle, you can use the TAN function in your calculator or programming language.

The syntax of the TAN function is usually "tan(x)", where x is the angle in radians. If your calculator or programming language uses degrees instead of radians, you may need to convert the angle to radians first using the conversion formula: radians = degrees * (pi/180).

For example, to find the value of the tangent of 30 degrees, you can use the TAN function as follows:

In degrees mode: TAN(30) = 0.57735027

In radians mode: TAN(30*pi/180) = 0.57735027

TAN can be used in various trigonometric equations and identities to solve for unknown sides or angles of a right triangle.

What is the value of q/p?(A) 162(B) 180(C) 324(D) 360(E) 720

Answers

We have that, if they put 40 chips in a hat, each one with the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, and each number is put on four chips. Four tokens are drawn from the hat at random and without replacement, the value of q/p, q,p as probabilities, will be given by 360, therefore, the correct option is (D) 360

How do we calculate the probability?

The probability that all four tokens have the same number (p) is equal to the total number of possible outcomes that meet that criterion divided by the total number of possible outcomes.

In this case, there are 10 possible numbers that could come up (1-10). Therefore, there are 10 possible outcomes for the four slips of paper that have the same number. Each outcome has the same probability of 1/10, so p = (1/10)^4 = 1/10000.

The probability that two of the slips have a number a and the other two have a number b (q) is equal to the total number of possible outcomes meeting that criterion divided by the total number of possible outcomes.

In this case, there are 10 possible numbers that could be drawn (1-10) and 2 ways to choose 2 different numbers out of 10, so there are 20 possible outcomes for two of the slips bearing a number and the other two bearing a number b. Each outcome has the same probability of 1/20, so q = (1/20)^4 = 1/3200000.

The ratio of q to p is q/p = 3200000/10000 = 360. Therefore, the value of q/p is 360.

The cost for a taxi ride is $3.00 for the first mile and $2.25 for each additional mile. Rewrite the expression 3.00 +2.25(m-1) for the cost of the taxi ride in dollars as a sum of two terms, where m represents the miles traveled. Show your work.

Answers

The rewritten expression  3.00 +2.25(m-1) is 2.25m + 0.75.

How to represent a situation with an expression?

The cost for a taxi ride is $3.00 for the first mile and $2.25 for each additional mile.

Therefore, let's rewrite the expression 3.00 +2.25(m-1) for the cost of the taxi ride in dollars as a sum of two terms, where m represents the miles travelled.

Hence,

m = miles travelled

Therefore, the cost using expression is as follows:

3 + 2.25(m - 1)

3 + 2.25m - 2.25

combine like terms

2.25m + 3 - 2.25

2.25m + 0.75

If two triangles have two pairs or corresponding angles and three pairs are corresponding sides that are congruent then the two triangles are congruent

Answers

AAS conguerence rule states that if two congruent triangles have any two pairs of corresponding angles that are equal and one pair of corresponding sides that are equal.

Triangles that are congruent have the same area since all of their matching angles and side lengths are the same.

You are aware that a triangle's three angles add up to 180 degrees. As a result, the third pair of angles is also equal if the first two pairs are (180° - sum of equal angles). Hence, if any two pairs of angles and one pair of corresponding sides are equal, two triangles are said to be congruent. It could be referred to as the AAS Congruence Rule.

There will be 30 yards of the string that will be leftover.

What are Arithmetic operations?

It is a field of mathematics that deals with the study of numbers and the operations on those numbers that are relevant to all other areas of mathematics. The basic operations included in it are addition, subtraction, multiplication, and division. The term "arithmetic operator" refers to the operator that does the calculation.

Given that,

Total Length of string = 50 yards.

The total number of students = 24.

Total used string = 24 × 30 = 720.

We know that 1 foot = 12 inches,

So, 150 feet = 1800 inches.

Therefore, yards of string leftover = (1800 - 720)/36

                                                         = 1080/36

                                                         = 30 yards.

Hence, there will be 30 yards of string that will be leftover.

True or False, suppose a hypothesis test was performed with a level of significance of 0.05. then if the null hypothesis is actually true, then there is a 5% chance that the researcher will end up accepting the alternative hypothesis in error.

Answers

If the null hypothesis is actually true, then there is a 5% chance that the researcher will end up accepting the alternative hypothesis in error, the statement is true.

If a hypothesis test is performed with a level of significance of 0.05 and the null hypothesis is actually true, then there is a 5% chance (or 0.05 probability) that the researcher will reject the null hypothesis and accept the alternative hypothesis in error.

This is known as a Type I error. The Type I error rate is determined by the level of significance of the test.

In other words, if the null hypothesis is true, but the researcher concludes that it is false (i.e., accepts the alternative hypothesis), this is an incorrect decision that is made with a probability of 0.05 or 5%, assuming a significance level of 0.05.

Andre wrote the inequality 3x + 10 <= 30 to plan his time. Describe what x , 3x , 10 , and 30 represent in this inequality

Answers

Andre can make 6 small cranes. X is the number of small cranes, 3x is the minutes, 10 is the minute for large cranes and 30 is the total time.

3x + 10 is less than or equal to 30

3 is the minutes for the small cranes

X is the number of small cranes

10 is the minutes for the large crane

30 is the total time limit

first, subtract 10 from 30, ( 30-10) which gives you 20 so

3x is less than or equal to 20.

To figure this out, divide 20 by 3, which gives you 6 as a quotient with a remainder of two minutes.
