Given that variance of a data set is:
Variance=σ²
the standard deviation is the square root of the variance:
thus
standard deviation= √(variance)
variance,σ²=104.04
thus
std deviation=√σ²=√104.04
thus
σ=10.2
Answer:
Step-by-step explanation:
pythagorean theorum: a^2 + b^2 = c^2
40 x40 = 1600
30 x 30=900
1600+900= 2500
Square root of 2500 =50
