Answer 1

Answer:

a.) (1,4), (-2,3), (0,4)

b.) (4,1), (3,-2), (4,0)

Step-by-step explanation:

a. When we want to find the reflection over the Y axis, that means the X coordinate signs reflect. For A, it says (-1,4). To reflect it, we reflect the X coordinate, so now it's (1,4) instead. You'll do that to the other two.

b. When rotating, you would switch the numbers of the coordinates and switch the sign of X. For the first one (-1,4), we'll switch it to (1,4). Not we'll switch the numbers around to make it (4,1). You'll do that for the other two

Answers

The data are discrete because the data can only take on specific values, So correct option is B.

What do you mean by discrete data?

Discrete data refers to data that can only take on specific, separate values. It is a type of data that can be counted or enumerated, but not measured. In other words, the values can't be expressed as fractions or decimals between two whole numbers. Some examples of discrete data include the number of siblings in a family, the number of pets owned by an individual, and the number of correct answers on a test. Discrete data is distinct from continuous data, which can take on any value within a certain range.

The data are discrete because the data can only take on specific values (e.g. a time of 20 minutes, 21 minutes, 22 minutes, etc.). They cannot take on any value in an interval, such as 20.5 minutes. Discrete data represent a countable number of values, while continuous data can take on any value within a given range.

The diagram below shows a rectangle with side lengths 4 and 8 and a square with side length 5. Three vertices of the square lie on three different sides of the rectangle, as shown. What is the area of the region inside both the square and the rectangle?

Answers

Answer:

The area of the region inside both the square and the rectangle is 37 square units.

Step-by-step explanation:

The area of the region inside both the square and the rectangle can be found by subtracting the areas of the four triangles outside the square from the area of the rectangle.

The area of the rectangle is 4 * 8 = 32 square units. The area of each triangle can be found using the formula for the area of a triangle, which is (base * height) / 2. The base of each triangle is half the length of the side of the square, which is 5 / 2 = 2.5 units. The height of each triangle is the difference in height between the rectangle and the square, which is 4 - 5 = -1 unit. The area of each triangle is (2.5 * -1) / 2 = -1.25 square units. The area of the four triangles outside the square is 4 * -1.25 = -5 square units.

The area of the region inside both the square and the rectangle is 32 + 5 = 37 square units.

Answers

The distribution is b) skewed.

The sum of the probabilities is: 1

How to find the answer

In a binomial distribution, p represents the probability of success. Success in the sense that the event of interest happens. In the model presented, the probability of success p is 0.4 since we are informed that 40% of adults watch a particular television show.

The next quantity of significance in a binomial model is the number of independent trials, n.

In our case there are 6 independent trials since we are told that 6 adults were selected at random. If we let the random variable K denote the number of adults out of the 6 who watch the television show, then K is a binomial random variable with parameters;

n = 6 and p = 0.4

A binomial distribution is only symmetric when either p is 0.5 or n is large. In the presented scenario none of these conditions is met since p is 0.4 while n is just 6 which is relatively small.

Thus we conclude that the distribution is not symmetric but rather skewed.

The sum of the probabilities is any discrete probability distribution such as the Bernoulli, binomial, negative binomial, Poisson, or the geometric distribution is always equal to 1. That's a rule of thumb.

The p-value for the test is  0.0062

What is the p-value of the test

To determine the p-value for Kara's hypothesis test, we need to calculate the test statistic and then find its corresponding p-value.

Let's start by calculating the sample mean and standard deviation of the given data:

Sample mean x = (46+43+41+48+51+51+52+42+51+54+40+53+46+46+46+39+47)/17 = 46.529

Sample standard deviation (s) = 4.547

We can use these values to calculate the t-statistic for the one-sample t-test:

t = (x - μ) / (s / sqrt(n))

where μ is the hypothesized population mean (50 hours), n is the sample size (17).

t = (46.529 - 50) / (4.547 / sqrt(17)) = -3.15

Using a t-distribution table with 16 degrees of freedom (n-1), we find that the p-value for a two-tailed test with a t-statistic of -3.15 is approximately  0.0062.

Therefore, the p-value for this hypothesis test is  0.0062

Since the p-value is less than the commonly used alpha level of 0.05, we reject the null hypothesis and conclude that there is evidence to suggest that the true mean work week for engineers in start-up companies is less than 50 hours.

Substitution:

Change the 2nd equation so x is on one side by subtracting 2y from both sides

Now we have

7x -y = 7
x = -2y + 6

Substitute the value of x in the 2nd equation for x in the first equation

7 (-2y + 6) - y = 7
Multiply

-14y + 42 -y = 7
Simplify

-15y + 42 = 7
Subtract 42 from both sides

-15y + 42 - 42 = 7 - 42
Simplify

-15y = -35

Divide both sides by -15

-15/-15y = -35/-15

y = 7/3 or 2 1/3

Substitute value of y into one equation to solve for x

7x - 7/3 = 7
Add 7/3 to both sides to isolate variable

7x -7/3 + 7/3 = 7 + 7/3
Simplify

7x = 28/3
Divide both sides by 7 to solve for x

Answers

Answer:

You would have to buy three raffle tickets to have a chance to receive all three pieces of merchandise.

Step-by-step explanation:

Each raffle ticket gives you a chance to win one of the three pieces of marching band merchandise: T-shirt, hat, or shorts. To have a chance of winning all three pieces, you would need to buy three separate raffle tickets, each with a chance to win a different piece of merchandise. This way, you would increase your chances of receiving all three pieces through the random selection process of the raffle.

If each raffle ticket has an equal chance to win any of the three pieces of merchandise, then you would have a 33% chance of winning any one piece of merchandise with each ticket you buy. To have a greater chance of winning all three pieces, you would need to buy multiple tickets.

For example, if you buy three tickets, the chance of winning all three pieces of merchandise would be (1/3) * (1/3) * (1/3) = 1/27. This means that you have a 1 in 27 chance of winning all three pieces of merchandise with three raffle tickets.

The solution is Option C.

The value of the quadratic equation is 5x² + 2x = 7

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

5x² + 2x = 7  

On simplifying the equation , we get

Subtracting 7 on both sides of the equation , we get

5x² + 2x - 7 = 0   be equation (1)

Now , the roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ -2 ± √ ( 4 - 4 ( 5 ) ( -7 ) ] / 10

x = [ -2 ± √ ( 144 ) ] / 10

x = ( -2 ± 12 ) / 10

So , the two roots of the equation are

x = ( -2 + 12 ) / 10

x = 10/10 = 1

And , x = ( -2 - 12 ) / 10

x = -14/10

x = -7/5

8. Use long division to find (2x³ - 7x² + 7x - 2) /(x - 2). Show your work

Answers

Answer:

2x² - 3x + 1

Step-by-step explanation:

x - 2 | 2x³ - 7x² + 7x - 2

    --   2x³ - 4x²                  <== 2x²

                - 3x² + 7x - 2

          --    - 3x² + 6x          <== -3x

                              x - 2

                     --       x - 2      <==  1    

                                   0 |  2x² - 3x + 1

Thus, the quotient is 2x² - 3x + 1

2. Calculate the volume of the prism.
(Hint: 2 inches is just half the length of
the triangular base. What is the length of
the base?)

Answers

Given the height (h) of the prism is 18 inches, we can calculate the volume of the prism as follows:

V = A * h
V = (4 * sqrt(3)) * 18
V = 72 * sqrt(3)

So, the volume of the prism is approximately 157.73 cubic inches.

By solving the equation 3x = x² - 4, we know that the positive solution of the given problem is x = 4.

What are equations?

Using the equal symbol, they are linked.

For instance, a formula might be 3x - 5 = 16. After solving this equation, we learn that the value of the variable x is 7.

So, using the given  information, form the following equation:

3x = x² - 4

Now, solve this equation as follows:

3x = x² - 4

0 = x² - 3x - 4

0 = (x-4)(x+1)

Then, x = 4 and x = -1

Therefore, by solving the equation 3x = x² - 4, we know that the positive solution to the given problem is x = 4.
