Someone please help! What is the domain and range of the relation?

Answers

Answer:

The domain is the set of all first elements of ordered pairs (x-coordinates).

The range is the set of all second elements of ordered pairs (y-coordinates).

Only the elements "used" by the relation or function constitute the range.

During a basketball game, the coach needs to select a player to make the free throw after a technical foul on the other team. There is a 68% chance that the coach will select you and a 26% chance that the coach will select your friend. What is the probability that you or your friend is selected to make the free throw?

Answers

For the probability of you or your friend add the probability of each together:

68% + 26% = 94%  (0.94 if you need it as a decimal)

Answer: there's an 42 percent chance that your friend might make a free throw.

Which of these expressions equal 15 when x=1/2 and y=3? Circle all that apply. Please help with this my teacher need me to work out xy+3 1/2+20x Btw guys 3 1/2 are mixed numbers if your wondering

Answers

Answer:

15

Step-by-step explanation:

First you would replace the x and y's with 1/2 and 3.

So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)

Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)

So you would first multiply and the parenthesis that I added mean multiplication.

1.5 + 3.5 + 10

So then all that is left to do is add because I multiplied everything out.

So it is 5 + 10 which is 15

In a certain town there were 403 robberies last year. This year the number of robberies has gone down 35%. How many robberies were there this year, to the nearest whole number?

Answers

Answer:

262

Step-by-step explanation:

From the Question, we know that:

In a certain town there were 403 robberies last year. This year the number of robberies has gone down 35%.

Step 1

Find the amount decreased

35% × 403

= 35/100 × 403

= 141.05

Step 2

The amount of robberies this year is:

= 403 - 141.05

= 261.95

Approximately to the nearest whole number = 262

Step-by-step explanation:

An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores?

Let d=(verbal SAT scores prior to taking the prep course)−(verbal SAT scores after taking the prep course)d=(verbal SAT scores prior to taking the prep course)−(verbal SAT scores after taking the prep course). Use a significance level of α=0.1 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course.

Student 1 2 3 4 5 6 7
Score on first SAT 500 380 560 430 450 360 560
Score on second SAT 540 470 580 450 480 400 600

Required:
a. State the null and alternative hypotheses for the test.
b. Find the value of the standard deviation of the paired differences. Round your answer to one decimal place.
c. Compute the value of the test statistic. Round your answer to three decimal places.
d. Determine the decision rule for rejecting the null hypothesis. Round the numerical portion of your answer to three decimal places.
e. Make the decision for the hypothesis test.

Answers

Answer:

Since the calculated value of t = -0.215  falls in the critical region so we accept Ha that SAT prep course improves the students' verbal SAT scores and reject the null hypothesis at significance level 0.05.

e. These results support the claim that the SAT prep course improves the students' verbal SAT scores.

Step-by-step explanation:

Student                        1      2      3       4      5         6          7

Score on first SAT    500   380 560   430  450    360    560

Score on second SAT 540 470 580  450    480    400    600

Difference d                -40  -90   -20    -20    -30     -40     -40     ∑ -280

d²                               1600  8100 400 400   900   1600  1600   ∑14600

a. Let the hypotheses be

H0:  ud= 0      against the claim Ha: ud ≠0

The degrees of freedom = n-1= 7-1= 6

The significance level is 0.05

The test statistic is

t= d`/sd/√n

The critical region is ║t║≤ t (0.025,6) = ±2.447

d`= ∑di/n= -280/7= -4

Sd²= ∑(di-d`)²/n-1 = 1/n-1 [∑di²- (∑di)²n]

= 1/6[14600-(-4)²/7] = [14600-2.2857/6]= 2432.952

b. Sd= 49.3249= 49.325

Therefore

c. t= d`/ sd/√n

t=   -4/ 49.325/√7

t= -4/18.6435 = -0.2145= -0.215

d. Since the calculated value of t = -0.215  falls in the critical region so we accept Ha that SAT prep course improves the students' verbal SAT scores and reject the null hypothesis at significance level 0.05

e. These results support the claim that the SAT prep course improves the students' verbal SAT scores.

Answers

Answer:

b, its the logical answer

Step-by-step explanation:

The value of the expression -4(x-5)+8x=9x-3 will be -5x = -23 The correct option is D.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is -4(x-5)+8x=9x-3. The solution to the expression is given below:-

-4(x-5)+8x=9x-3

-4x + 20 + 8x= 9x - 3

4x - 9x = -20 - 3

-5x = -23

Therefore, the value of the expression -4(x-5)+8x=9x-3 will be -5x = -23 The correct option is D.

What is of volume of cylinder?

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

Volume of cylinder is the can be given as,

[tex]V=\pi r^2h[/tex]

Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.

Choir is selling Pringle chips to raise money for a field trip. The container has a diameter of 9 inches and a height of 32 inches.

As the radius is half of the diameter. Thus, the radius of the container is,

[tex]r=\dfrac{9}{2}\\r=4.5\rm\; in[/tex]

As this container is in the shape of cylinder. Thus, the volume of container can be found out using the above formula as,

[tex]V=\pi (4.5)^2(32)[/tex]
