Apolling agency wants to determine the size of a random sample needed to estimate the percentage of voters a particular candidate will receive in the next election. the estimate should have a margin of error of no more than 2.2 percentage points at a 95% level of confidence. a. how large a sample should the agency take? b. would a 1% margin of error require a larger or smaller sample size than in part a? c. if the degree of confidence were lowered to 90%, with the margin of error no more than 2.2%, would that require a larger or smaller sample size than the result for part a?

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
