Answer:

Pr = 7\%

Step-by-step explanation:

Given

See attachment for graph

Required

Find P(Junior|Male)

To do this, we first calculate the total students.

Total = 4 + 6 + 2 + 2 + 3 + 4 + 6 + 3

Total = 30

Next, select the value in the cell that intersects Male and Junior

Male\ and\ Junior = 2

Hence, the probability is

Pr = \frac{Male\ and\ Junior}{Total}

Pr = \frac{2}{30}

Pr = 0.067

Express as percentage

Pr = 0.067*100\%

Pr = 6.7\%

Approximate

Pr = 7\%

Solve for v.<br> - 7(-2v+5) – 4y= 2(1-9) – 7<br> Simplify your answer as much as possible.
vaieri [72.5K]

Answer:

v = 6/7 + 2/7y

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-7(-2v + 5) - 4y = 2(1 - 9) - 7

14v - 35 - 4y = 2 - 18 - 7

Step 2:  Add 35 to both sides

14v - 35 + 35 - 4y = -23 + 35 + 4y

14v = 12 + 4y

Step 3:  Divide both sides by 10

14v / 14 = 12 + 4y / 14

v = 6/7 + 2/7y

Answer:  v = 6/7 + 2/7y
