First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Is this what you’re talking about

Answer:
$1.5 and $8.75
Step-by-step explanation:
Given data
let tables be x and chairs be y
The total cost to rent 3 chairs and 2 tables is $22
so
3x+2y=22----------1
The total cost to rent 5 chairs and 6 tables is $60
so
5x+6y=60---------2
the system of equation is
3x+2y=22----------1X 6
5x+6y=60---------2X 2
18x+12y= 132
- 10x+12y=120
8x+0y= 12
8x= 12
divide both sides by 8
x= 12/8
x=$1.5
put x= 1.5 in 2
5(1.5)+6y=60---------2
7.5+6y=60
6y=60-7.5
6y=52.5
divide both sides by 6
y= 52.5/6
y=$8.75
