Answer:

5.94

Step-by-step explanation:

To find the mean, you need to add the numbers and divide it by however many numbers you have.

4.7 + 4.2 + 8.2 + 9.5 + 3.1 = 29.7

There are 5 numbers, so divide the sum by 5

29.7/5 = 5.94

List all the pairs of integers with a product of 36. then find the pair whose sum is 20

RoseWind [281]

This is an excellent practice for the solution of quadratic equations.

1*36=36 => (1,36)
2*18=36 => (2,18)
3*12=36 => (3,12)
4*9=36 => (4,9)
6*6=36 => (6,6)
9*4=36 => (9,4)
12*3=36 => (12,3)
18*2=36 => (18,2)
36*1=36 => (36,1)

We can see that the sum decreases until the two factors are close (or equal) and then increases again.

The pair of integers with a sum of 20 is therefore (2,18) or (18,2).
