When jeremy surveyed thirty 7th-grade students at the community pool, he found that 2/15 had not read at least one book during july. he knows there are about 200 7th-grade students in his community, so he infers that about 40 of them did not read any books in july. is that a good inference? explain.

He didnt make a good inference, because the ratio is not in proportion to 2/15. The right inference would be 26 students who didnt read any books in July. The sample may be biased since it was limited to those at the pool.

Step-by-step explanation:

I did the assignment on edg :)

answer: i think it is (1,-2)

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
