9 ft is the answer because a square has four sides, so 36 divided by 4 is 9
Answer:
m=0
Step-by-step explanation:
The slope is m=0 and the Y intercept should be b= -4 .
Circumference of a circle =2πr
6.28=2πr
3.14=πr
3.14/π=r
3.14/3.14=r
<h2>therefore,r=1</h2>
For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
