Step-by-step explanation:
Given that a contractor records the areas, in square feet, of several houses in a neighborhood to determine data about the neighborhood.
Let X1, X2,...Xn be the data set
We find mean of this by the formula sum/n
Mean =
Now variance is calculated as sum of squares of deviations of each entry from this mean.
Var(x) =
Standard deviation = square root of variance
Thus first mean, then variance then sd deviation is calculated.
Answer:
Well a number is (x) {unknown}
Its 17 more
So x+17=85
Now solve
subtract 17 on both sides
x=68
So the number is 68
