Answer:
79.1
Step-by-step explanation:
Given that :
Mean, μ = 62
Standard deviation, σ = 5.7
The value, x that is +3 standard deviations from the mean :
x = μ + 3(σ)
x = 62 + 3(5.7)
x = 62 + 17.1
x = 79.1
Answer: Kim is 16 and Alan is 20
Kim => x
Alan => y
Kim is 4/5 as old as Alan =>
In four years, she will be 5/6 as old as he will be =>
Solving the system we obtain x=16 and y=20
