Answer:

(x-4) is not a factor of f(x)=x³-2x²+5x+1

Step-by-step explanation:

Uding the remainder theorem,(x-4) is a factor if the remainder is 0

Liz wants to estimate the percentage of people who rent their home. She surveys 320 individuals and finds that 176 rent their ho
SOVA2 [1]

Answer: 0.065

Step-by-step explanation:

Given : Sample size : n= 320

The sample proportion of people who rent their home : p=\dfrac{176}{320}=0.55

Significance level : \alpha:1-0.98=0.02

Then , Critical value : z_{\alpha/2}=2.33

The formula to find the margin of error : -

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\\Rightarrow\ E=(2.33)\sqrt{\dfrac{0.55(1-0.55)}{320}}\\\\\Rightarrow\ E=0.064799034281\approx0.065

Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065
