The ratio is 4:5 girls to boys
To answer this question you will need to calculate the mean for each of the Shifts and then compare those means to the mean of all the data given. I have attached a picture of the means for each shift and the population mean (all the data).
Shift 1 is the closest to the population mean. It is 37.4, and the population mean is 35.9.

I'd like to assume that the triangle is a right triangle and you solve for x so...
133 + c = 180 (supplementary property to find one angle of triangle)
c = 47
x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43
Therefore, x is 43 degrees
Answer:
The answer to your question is below.
Step-by-step explanation:
14.- Use proportions to solve these problems.

14(x + 6) = 10(x + 9)
14x + 84 = 10x + 90
14x - 10x = 90 - 84
4x = 6
x = 6/4
x = 3/2
15.- 
10(x - 1) = 8(x + 2)
10x - 10 = 8x + 16
10x - 8x = 16 + 10
2x = 26
x = 26 / 2
x = 13
16.- 
5(x + 1) = 9(10/3)
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25 / 5
x = 5
