Margin of error: 0.04; confidence level: 95%; from a prior study, bold p with bold overparenthesis on top is estimated by the decimal equivalent of 89%. find the sample size.

235

Step-by-step explanation:

The formula to calculate the sample size  :-

Given :  Estimated proportion

Margin of error :

Significance level :

Critical value :

Now, the required sample size will be :-

Hence, the required minimum sample size = 235

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

idk this answer sorry cant on this one.
