Let's say the numbers are "a" and "b"
hmm say "a" is the smaller, and "b" the greater
so "b" is "4 more than 5 times" "a"
so... 5 times "a" is 5*a or 5a
4 more than "that", will be "that" + 4
or
5a + 4
so.. whatever "a" is, "b" is 5a+4
now, their sum is 22, as opposed to "zz" hehe
so

solve for "a", to see what the smaller one is
what's "b"? well, b = 5a + 4
F(b)-F(a)/b-a
A=10 B= -2
F(a) =4 F(b)=17
17-4/-2-10
13/-12
Yea I have no proof to do that much cause
Answer:
C. The normal distribution can be used because the original population has a normal distribution.
Step-by-step explanation:
When the original population has a normal distribution, we can use the normal distribution to solve the exercise.
In this problem, we have that:
The original population are the adult females.
The problem states that:
The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of
7.8 cm.
So the correct answer is
C. The normal distribution can be used because the original population has a normal distribution.
