Answer:
0.0417
Step-by-step explanation:
Given the following;
p = 0.7, n=121
The sampling distribution of sample proportion will be approximately normal with mean
\mu_{\hat{p}}=p=0.7
and standard deviation
\sigma_{\hat{p}}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.7\cdot 0.2}{121}}=0.0417

Answer:
80 square yards
Step-by-step explanation:
We know we have a width of 8 yards and a perimeter of 36.
how I figured it out was:
36=(8*2) * (x*2)
8*2=16
36-16=10
So now we know the length and width.
area of a rectangle is lw (length * width)
10*8=80.
