The next number would be 160
Answer:
it's T it's not e because the middle bit is small
Answer:
M = 1.5
Step-by-step explanation:
First, apply the distributive property to the problem. For this, you will multiply 4 x m, then 4 x 3.
Now, your problem looks like
4m + 12 = 18
Next, you need to get the variable isolated. For this, you need to subtract 12 from both sides.
Now, your problem looks like
4m = 6
Next, you can divide both sides by the non-constant term, which is 4m, so divide by 4.
Now, your problem looks like
M = 1.5

Variance is given by s^2 = [summation (x - mean)^2] / n.
mean = (90 + 75 + 72 + 88 + 85) / 5 = 82
Variance = [(90 - 82)^2 + (75 - 82)^2 + (72 - 82)^2 + (88 - 82)^2 + (85 - 82)] / 5
= [8^2 + (-7)^2 + (-10)^2 + 6^2 + 3^2] / 5
= (64 + 49 + 100 + 36 + 9] / 5
= 258 / 5
Therefore, the value of the numerator of the calculation of the variance of the data set is 258.
