30inc=76.2cm
76.2*pi=76.2pi
1cm=0.0328084 foot
1 mile=<span>5280 ft
</span>5280/0.0328084=160934.4
1 mile=160934.4 cm
160934.4 /76.2pi=672.27
672 revolutions i think
Answer: D) 1.47x + 1.61y = 229.11
Explanation: The amount of beverages and candy sold combined (addition) should be set equal to the targeted goal per game ($229.11).
Answer:
For this case we know that the confidence level is 90% so then the significance level is 
and 
. And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:
And the best option would be:
1.645
Step-by-step explanation:
We assume that the parameter of interest is 
and we can assume that the distribution for this parameter is normally distributed so then the confidence interval assuming a two sided interval is given by:
Where 
represent the estimator for the parameter, SE the standard error and 
the critical value.
For this case we know that the confidence level is 90% so then the significance level is and . And we can find in the normal standard distribution a value who accumulates 0.5 of the area on each tail and we got:
And the best option would be:
1.645
