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.

Can someone help me with this
slega [8]

Answer:

4π

Step-by-step explanation:

This is a sinusoidal function.

The period of the function is basically the length from one wave crest to the next crest. We can take any 2 subsequent crests.

Lets take our first crest to be at 3π

The next one will be at 7π, as we can see

So, the length from one crest to the next is the period, which is:

7π - 3π

= 4π

Third answer choice is right, 4π is the period.
