Answer to Problem 8E

Yes

Explanation of Solution

Given:A construction company is ordering cement to pour the garage floor of a new house.

In this case, the cement is going to be used for pouring the garage floor by mixing it with sand and some other components. And any change in proportion of cement needed in the mixture will make the floor weak and vulnerable. So, a certain degree of precision is needed in order to completion of the order.
