Answer:

The sample size needed is 40000.

Step-by-step explanation:

The sample size needed is:

n = \frac{1}{M^{2}}

Use this formula to determine the sample size needed for a margin of error of 0.005

This is n when M = 0.005. So

n = \frac{1}{M^{2}}

n = \frac{1}{0.005^{2}}

n = 40000

The sample size needed is 40000.

For what value of y does 125=(1/25)^y-1
Alex777 [14]

Answer:y=-1/2

Step-by-step explanation:

125=(1/25)^(y-1)

5^3=(5^(-2))^(y-1)

5^3=5^(-2(y-1))

The same base eliminate each other we then have

3=-2(y-1)

3=-2y+2

Collect like terms

2y=2-3

2y=-1

Divide both sides by 2

2y/2=-1/2

y=-1/2
