The variance (σ^2) is the square of the differences between the mean and each data.
The problem says that the program reports a mean of 31.5 and a standard deviation of 2.5, so you have to elevate the standar deviation to the power 2:
σ^2 = (2.5)^2
σ^2 = 6.30
<span>
What is the variance of the data?
</span> The variance of the data is 6.30, so the the correct option is D.
Answer:
2.6×10^2
3.6×10^2
Step-by-step explanation:
2.5×103=257.5
257.5= 2.575 × 10^2
257.5= 2.6 × 10^2 ( rounding off)
3.442×104= 357.968
3.442×104= 3.57968 × 10^2
3.442×104= 3.6 × 10^2 (rounding off)

Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line
m = 
= 
= 2
