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
I think we have found them and cared for them I don't think it's right b/c I guessed.
Answer:
D if car's length is 180 and not 108
Step-by-step explanation:
Truck is 75% longer than the car implies that the length of the truck is 175% (100+75 = 175) of the length of the car.
175/100 × 108
= 189 inches
None of the above
If we take the car's length to be 180 inches, then
175/100 × 180 = 315 inches
