Answer:
7.53 x 10²
Step-by-step explanation:
10² two time the 10 is 100
48 = 2*2*2*2*3
84 = 2*2*3*7
Looking for common factors we get the GCF to be 2*2*3 = 12
Its B

Step-by-step explanation:
Answer:
330
Step-by-step explanation:
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

What is the variance of the data?
</span> The variance of the data is 6.30, so the the correct option is D.
