Answer:
C) v≤-5
Step-by-step explanation:

Divide each side by 4,

Answer:
The sample size n = 4225
Step-by-step explanation:
We will use maximum error formula = 
but we will find sample size "n"

Squaring on both sides , we get

Given 99% confidence interval (z value) = 2.56
given maximum error = 0.02

n≤
( here S.D = p(1-p) ≤ 1/2
on simplification , we get n = 4225
<u>Conclusion</u>:
The sample size of two samples is n = 4225
<u>verification</u>:-
We will use maximum error formula =
=
= 0.0196
substitute all values and simplify we get maximum error is 0.02
A.125
Because to get from 5 to 25 you need to multiply by 5 so 25 times five equals 125
