Answer:
The number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his mean (58)
Step-by-step explanation:
A normal random variable with mean Mu = 58 and standard deviation sd = 11 is standardized with the transformation (z-score):
Z = (X - Mu) / sd = (X - 58) / 11
For a value of 74 for X, Z = (74 - 58) / 11 = 1.4545 > 0.
The z-score when X = 74 is 1.4545 > 0
This means that the number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his average (58)
A (b-c)=d
ab-ac=d
ab-d=a.c
Divide both sides by a
Your answer = ab-d/a
Answer choice C
Answer:
on squaring complete term
x + 81 = 784
x = 784 - 81
x = 703
Step-by-step explanation:
6a=p
