In a survey of 40 clemson students, it was found that the mean age (in years) when they would like to get married is 27.4 with a standard deviation of 6. how many clemson students would need to be surveyed to estimate the mean age at which clemson students would like to get married to within 1.5 years with 90% confidence?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer is c just got it on ed

step-by-step explanation:

the answer will be b x² +x-1
