That looks confusing
Step-by-step explanation:
Answer:
A) 1/3200000
B) 19/20
Step-by-step explanation:
Percentage population of graduates = 5
Proportion of graduates from 100 random samples = percentage × number of samples
Proportion of graduates = 0.05 × 100 = 5
Probability of having 5 graduates among the 100 random samples:
P(1 graduate) = possible outcome / total required outcome
P(1 graduate) = (5 / 100) = 1/20
P(5 graduates) = (1/20)^5
P(5 graduates) = 1/3200000
Probability of never being a graduate = (1 - probability of being a graduate)
Probability of never being a graduate = ( 1 - (1/20)) = 19/20

Answer:
m = 1/3
Step-by-step explanation:
<u>Step 1</u>. Pick a line of the table to use as (x1, y1).
<u>Step 2</u>. Pick a different line of the table to use as (x2, y2).
<u>Step 3</u>. Use the slope formula:
m = (y2 -y1)/(x2 -x1)
<u>Step 4</u>. Simplify the result.

Here are these steps for this problem.
1, 2. use (x1, y1) = (-9, -5) and (x2, y2) = (-3, -3)
3. m = (-3 -(-5))/(-3 -(-9)) = 2/6
4. m = 1/3
