Answer:
a) The mean of the data set is $33,691.13 and can be calculated by finding the average of the sum of the eight salaries.
b) The five number of the data set is {27,274; 30,421; 32,941.5; 35,682; 44,166} and can be calculated by finding the minimum, maximum, median, and interquartile range values.
c) The standard deviation of the data set is 4773.50 and can be calculated by finding the square root of the average of the sum of the differences from the mean squared.
One possible answer is 120°
Answer:
76.5
Step-by-step explanation:
if the area is 76.5^2, then all you have to do is take the square root, and it is 76.5
We have to see how many times 130 fits into 1494.23:

So now we have to multiply this by the amount of time needed for 130 meters:
11.4940*1=11.4940.
So the answer is 11.4940 minutes.
180 degrees in a triangle. so 180-90-31=59
