suppose the z-score for gwen’s math act score is 1.2, what is the correct interpretation of this z-score?

See below

Step-by-step explanation:

The z-score represents how many standard deviations are either above or below the mean. In this case, because the z-score is 1.2, this means that Gwen scored 1.2 standard deviations higher than the mean score, essentially meaning she did slightly better than most people.

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.
