You posted this question twice, hah.
Do you need work to show it?

There are 5280 feet in a mile
There are 3600 seconds in an hour
to get 40 miles per hour
we multiply 40 by 5280 and divide by 3600
40 * 5280 / 3600
this gets us 58.666666...
but since they want us to round to the nearest whole number, our answer would be 59 feet per second

Answer:
c. It does not guarantee that the best regression model will be found.
Step-by-step explanation:
Backward elimination (or deletion) procedure requires a subsequent removal of individual independent variables in an equation to derive an appropriate regression equation. It is a step-wise operation which make use of a predefined criterion for essential variables.
One of its main importance is that it ensure that the best regression model is found by removal of inconsequential variables.
Therefore, the appropriate answer to the given question is option C.
