Answer: 60 books

Step-by-step explanation:

One customer buys 1/4 of a book vendor's books , another buys 1/3 of his books ,and the third person buys 1/6 of his books.

The lowest common multiple of 4, 3 and 6 is 12

1/4 × 12 = 3

1/3 × 12 = 4

1/6 × 12 = 2

We add all together= 3+4+2= 9

So we've gotten our numerators as 9 and denominator as 12 which is 9/12 = 3/4

Since the total books bought is 3/4. The fraction of books left will be

1-3/4 = 1/4

The book vendor has 15 books left. So we divide 15 by 1/4.

= 15 ÷ 1/4

= 15 × 4

= 60

Liula [17]

Answer:

b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost

Step-by-step explanation:

The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.

If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
