Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
Answer:
$20196
Step-by-step explanation:
12 × 9 × 6 = 648 cubic feet ( volume of slab )
3 feet to a yard
So 648 ÷ 3 = 216
Multiply this by 1.1 to add an extra 10%
237.6 Cubic Yards Needed
$85 × 237.6 = $ 20196
