5to the negative third power rewritten with a positive exponent

C). 30

Step-by-step explanation:

First we arrange the data in ascending order

Week 1= 24,27,31,34,36,41,45

Week 2= 16, 18,20,25,31,34,38

To calculate for the mean

Let's find the mean of first week separate, the mean if second week separate, then add it up and divide by two.

Let's call first week1 mean "mean 1"

Let's call first week2 mean "mean 2"

Mean 1 = (24+27+31+34+36+41+45)/7

= 338/7

= 34

Mean 2= (16+18+20+25+31+34+38)/7

= 182/7

= 26

Total mean =( 34+26)/2

= 60/2
