Answer:
9343620
Step-by-step explanation:
put commas where they need to be but all you have to do is multiply them together unless you're working with a rectangular prism just multiply by 2 then
3/70=x/100
(3/70)*100=x
300/70=x
x=30/7=4.2857 roughly
11.8 x 5.8= 68.44
now to find the length of the other side of the triangle,
11 - 5.8= 6
6 x 7.5= 45 ÷ 2= 22.5
22.5 + 68.44= 90.94
Answer: 37
Step-by-step explanation:
Given : Significance level : 
Critical value : 
margin of error : E= 1 mile per gallon
Population standard deviation:
miles per gallon.
We know that when the population standard deviation is known then the formula to find the sample size is given by :

[Round to the next whole number.]
Hence, the required number of automobiles should be used in the test = 37
