Answer:
324
Step-by-step explanation:
given that in a poll, 74% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicted of murder?"
i.e. Sample proportion 
Margin of error = 4% = 0.04
Confidence level =90%
Z critical value for 90% = 1.645
Margin of error = 1.645 * std error
Hence std error = 
Std error is also equal to

Sample size should be 324.
The formula is sample size = (Z critical value)^2 (pq)/(Margin of error )^2
35 :) If you change the percent into a decimal (0.70) and multiply that by 50, you will get the answer!
Answer:
f(4f + 1)
Step-by-step explanation:
Given
4f² + f ← factor out f from each term
= f(4f + 1)

Answer:
AB , AD , EF , EH all intersect AE ⇒ answer (c)
Step-by-step explanation:
∵ AE segment passing through A and E
∴ Each segment passing through A and E intersects AE
∴ AB intersects AE at A
∴ AD intersects AE at A
∴ EF intersects AE at E
∴ EH intersects AE at E
∴ The answer is (c)
