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

pairs of rows (or columns) in the multiplication table and by analyzing
simple drawings that indicate the relative size of quantities.
Answer:
Patty will need 5 more tiles than Jake.
Step-by-step explanation:
8 = 2 × 4, 28 ÷ 2 = 14
9 = 3 × 3, 28 ÷ 3 = 9.3...
14 - 9 = 5
