Many fundraisers ask for donations using email and text messages. A paper describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by email is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.8% of those who received and opened an email request for a donation and 7.9% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (email or text message) and suppose that the given percentages are based on sample sizes of 2,000 (the actual sample sizes in the experiment were much larger). (Let p1 be the proportion who make a donation after receiving an email, and p2 be the proportion who make a donation after receiving a text message.)
The study described is an experiment with two treatments. What are the two treatments?
a. fundraisers
b. donations using text message
c. charitable giving
d. donations using email
e. deadlines

Answer:

[tex]Rise = 11^\circ C[/tex]

Step-by-step explanation:

Given

[tex]Midnight \to -7^\circ C[/tex]

[tex]Midday \to 4^\circ C[/tex]

Required

The temperature rise

This is the difference between the final and the initial temperature

[tex]Rise = Midday - Midnight[/tex]

[tex]Rise = 4^\circ C - -7^\circ C[/tex]

[tex]Rise = 4^\circ C +7^\circ C[/tex]

[tex]Rise = 11^\circ C[/tex]

Answer:

The answer is w=3

Step-by-step explanation:

6w+2=20

6w=18

w=3

Answer:

W = 3

Step-by-step explanation:

6W + 2 = 20

6W + 2-2 = 20-2

6W = 18

6W/6 = 18/6

w = 3

Billy would need to mow 4 laws to make over $25.

Answer:

x=26/7

y=115/7

Step-by-step explanation:

7x+10=36>>subtract 10 from 10 and 36 you get 7x=26>>>divide both sides by 7>>>>x=26/7

To find find y you substitute the x for 26/7>>2(26/7)+9=115/7

Hi there!

[tex]\large\boxed{y = -7}[/tex]

4y - 2(1 - y) = -44

Begin by distributing -2:

4y - 2(1) - 2(-y) = -44

Simplify. A negative times a negative equals positive.

4y - 2 + 2y = -44

Combine like terms:

6y - 2 = -44

Add 2 to both sides:

6y = -42

Divide both sides by 6:

y = -7

Answer:

B.) Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, 2, and 3. The graph intersects the y axis at a point between 15 and 20.

Step-by-step explanation:

Cubic graph falls to the left and rises to the right. Option C is the correct answer.

We need to identify the graph graph best represents the function f(x) = (x − 1)(x + 3)(x − 3).

A cubic function is a polynomial function of degree 3 and is of the form f(x) = ax³+ bx² + cx + d, where a, b, c, and d are real numbers and a ≠ 0.

Graph the cubic using its end behaviour and a few selected points. Falls to the left and rises to the right.

Plot these points on graph (-1, 16), (0, 9), (1, 0), (2, -5) and (3, 0).

Therefore, option C is the correct answer.

Answer:

B.) 3x=15

Step-by-step explanation:

This is because you multiply 3 by x and if x=5 then it would be 3x5 thus resulting in 15

1) Plug 5 into all the spots for x. See if it makes the equation true.

A. 2+5 = 3  Nope

B. 3(5) = 15 Yep

C. 5/2 = 10 Nuh-uh

D. 5-7 = 12  Nah

B is the answer :)

I'm not sure if you need the answer to #2 but I'll answer it anyway. :)

2) An equation has to have a solution. This means it has an equal sign. C is the only one that has an equal sign.

Step-by-step explanation:

Answer and Step-by-step explanation:

We are given a triangle and are asked to solve for the value of y.

We know that the angles in a triangle add up to 180 degrees. So let's add all of the angles together and equal it to 180.

2y + y + 10 + 50 = 180

Combine like terms.

3y + 60 = 180

Now subtract each side by 60.

3y = 120

Finally, divide each side by 3.

y = 40

We get the value of y to be 40.

The equation in slope intercept form

Solving (3):

[tex]m = -1[/tex]

[tex](x_1,y_1) =(4,-4)[/tex]

The equation in slope intercept form is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = -1(x - 4) -4[/tex]

Expand

[tex]y = -x + 4 -4[/tex]

[tex]y = -x[/tex]

Solving (5):

[tex]m = -3[/tex]

[tex](x_1,y_1) = (1,-5)[/tex]

The equation in slope intercept form is:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = -3(x - 1) - 5[/tex]

Expand

[tex]y = -3x + 3 - 5[/tex]

[tex]y = -3x -2[/tex]
