Answer:
1992.38
Step-by-step explanation:
The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.
Sum:
1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56
Divide:
There are 12 numbers, so divide 23908.56 by 12:
23908.56 / 12 = 1992.38
The average is thus 1992.38.

D) is the answer i already done that question
Radius is half of diameter.
Circumference can be found using the equation C=2(pi)r or C=(pi)d.
r=radius, d=diameter
(pi) is about 3.14 or 22/7
Subtract the 18 from the 78 then multiply both sides by -1, then divide by 5.
