Suppose the american national elections studies agency (anes) wishes to conduct a survey. it plans to ask a yes/no question to determine if those surveyed plan to vote for a certain candidate. one proposal is to randomly select 400 people and another proposal is to randomly select 1600 people.
which of the following is true regarding the sample proportion ^ p of "yes" responses?
o the sample proportion from the sample of 400 is more likely to be close to the true population proportion, p .
o the sample proportion from sample of 1,600 is more likely to be close to the true population proportion, p .
o the sample proportion, ^ p , in either proposal is equally likely to be close to the true population proportion, p , since the sampling is random

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

i will pick c put check it over to be sure

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
