Answer:
(A)
Step-by-step explanation:
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.
Answer:
46.85
Step-by-step explanation:
let the number be n then doubling it is 2n and
2n + 4 = 97.7 ( subtract 4 from both sides )
2n = 93.7 ( divide both sides by 2 )
n = 46.85
