Mean is average
so we have 4 numbers
sum them then divide by 4
(32+31+37+44)=144
divide by 4
144/4=36
answer is C

Answer:
see attached
Step-by-step explanation:
We're not quite sure what the question is.
It appears you may be interested in the names of the groups of 3 digits. Each such group is called a "period." Each period is named for the place value of its right-most digit.
The period just to the left of the decimal point is the "ones" period. To the left of that is the "thousands" period, and to its left is the "millions" period.
When writing the name of a number, the name of the three digits within a period is given, followed by the period name (if it is greater than "ones"). This continues left to right, until you get to the decimal point. For example, the number shown is ...
eight hundred sixty-two thousand seven hundred ninety-four
Let:
x = the middle integer
Then the 3 consecutive integers are:
x - 1, x, x + 1
The product of the first and the third integer:
(x - 1)*(x + 1) = x^2 - 1
is equal to:
3 more than 3 times the second integer:
3x + 3
So:
x^2 - 1 = 3x + 3
Solve:
x^2 - 3x - 4 = 0
(x-4)(x+1) = 0
x = -1 and 4
Since x is the middle integer, we have two sets of solutions:
3,4,5 and -2,-1,0
