Answer:

Vincent and Reyna.

Step-by-step explanation:

To compare the performance of three potential employees, we have to convert each score into z score.  

Vincent got 83.5 for a N(68.2, 99)

Z score for Vincent =

Kaitlyn got 251.2 with N(238, 22)

Z score for Kaitlyn =

Reyna got a score of 8.04 for N(7.27, 0.7)

Z score for Reyna =

Z score higher is a better option since all z scores are positive

Hence here Reyna is a good option.

Pani-rosa [81]
For arithmetic sequence

a_{n}=a_{1}+d(n-1)

a_{1}=4, d=2

a_{n}= 4+2(n-1)

a_{n}=4+2n-2=2+2n

a_{n} = 2+2n
