The number of regular seasons wins for 10 football teams in a given season are bellow. Determine the range, mean, variance, and standard deviation of 2,10,15,3,12,7,13,6,3,10

Step-by-step explanation:

Range is calculated by the highest value in a given data set - lowest value

Given the data set above, the highest value is 15, while the lowest value is 2

To calculate range, we insert the values into the formula:

Range = 15 - 2 = 13

2) To calculate mean, we sum the total of all values in the data set and divide by the number of values

Mean = 2+ 10 +15+ 3+12+7+13+6+3+10/10

= 83/10 = 8.3

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
