4A = E , A=E/4-----(1)
B/4=E , B=4E-------(2)
C+4=E, C=E-4------(3)
D-4=E, D=E+4------(4)
Substitute all values in 5th equation,
A+B+C+D=100 = E/4 + 4E + E-4+ E+4 =100
E/4 + 6E = 100
25E = 400
E=16 ANS....
Answer:
a) 10.6; 48.7; within
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 29.6
Standard deviation = 6.35
"According to the Empirical Rule, the ages of nearly all lead actresses will be between______________and_____________ years.
Nearly all(99.7%) will be within 3 standard deviations from the mean.
So from 29.6 - 3*6.35 = 10.6 years to 29.6 + 3*6.35 = 48.7 years.
Anna was 11-years old, so she was within this range.
So the correct answer is
a) 10.6; 48.7; within
