Answer:
Rachel
Step-by-step explanation:
We need to measure how far (towards the left) are the students from the mean in<em> “standard deviations units”</em>.
That is to say, if t is the time the student ran the mile and s is the standard deviation of the class, we must find an x such that
mean - x*s = t
For Rachel we have
11 - x*3 = 8, so x = 1.
Rachel is <em>1 standard deviation far (to the left) from the mean</em> of her class
For Kenji we have
9 - x*2 = 8.5, so x = 0.25
Kenji is <em>0.25 standard deviations far (to the left) from the mean</em> of his class
For Nedda we have
7 - x*4 = 8, so x = 0.25
Nedda is also 0.25 standard deviations far (to the left) from the mean of his class.
As Rachel is the farthest from the mean of her class in term of standard deviations, Rachel is the fastest runner with respect to her class.

Using the probability concept, it is found that there is a 0.8456= 84.56% probability that client A lives to be 20 years old.
<h3 /><h3>What is probability?</h3>
A probability is the chances of happening of any event from the random variables. A probability is the number of desired outcomes divided by the number of total outcomes, that is:
In this problem:
Out of 100,000 clients, 84,560 lives to age 64, hence
Then:
There is a 0.8456= 84.56% probability that client A lives to be 30 years old.

Answer: 4*(-3x +0.6y - 12)
Step-by-step explanation:
-12x+2.4y-48
Factor out 4
4*((-12x/4)+(2.4/4)y-(48/4)
4*(-3x +0.6y - 12)
