A random sample of 10 subjects have weights with a standard deviation of 11.7485 kg. What is the variance of their weights? Be sure to include the appropriate units with the result. The variance of the sample data is
(Round to four decimal places as needed.)

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

a+b=c is your answer
