Answer:
Multiply fee.10miles,30mileMultiply fee.10miles,30miles,inch,2,inch,2
Step-by-step explanation:
1 mile = 5280 feet.
Convert the dimensions to feet:
10 miles = 5280 x 10 = 52,800 feet
30 miles = 5280 x 30 = 158,400 feet
Multiply together to get the area:
52,800 x 158,400 = 8,363,520,000 square feet.
1 inch = 1/12 of a foot.
Multiply the area by 1/12 for the volume of rain:
8,363,520,000 x 1/12 = 696,960,000 cubic feet.
Answer: a) Required minimum sample size= 219
b) Required minimum sample size= 271
As per given , we have
Margin of error : E= 5% =0.05
Critical z-value for 90% confidence interval :
a) Prior estimate of true proportion: p=28%=0.28
Formula to find the sample size :-
Required minimum sample size= 219
b) If no estimate of true proportion is given , then we assume p= 0.5
Required minimum sample size= 271
D) g(x) = 2x-8
the first option is correct
since value of a will be found through division.
Given that 4000 items are checked in one month, let the number of detective items be represented as y.
Quality control finds on average that 0.026% of the items in the factory are detective. This implies that
When 4000 items are checked, we have the number of detective items to be evaluated as
Hence, the number of detective items is 1.04.
