The correct answer is:
0.01$ (c)
Step-by-step explanation:
Standard deviation is a measure of how spread out numbers are from the mean value. The formula for standard deviation is given by:
Variance is a measure of the squared differences from the mean.
Variance is simply the square of the standard deviation. It is mathematically shown as:
Now in our example,
Stabnard deviation = $0.10
Variance = (standard deviation)²
Variance = (0.10)²
Variance = $0.01
Length = x
width = y
y = 16
x = 2y
x = 2(16)
x = 32
perimeter = 2x + 2y
= 2(32) + 2(16)
= 64 + 32
= 96
