Answer:
(c) 118/V100 11.8
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size can be approximated to a normal distribution with mean
and standard deviation 
In this problem, we have that:

So

So the correct answer is:
(c) 118/V100 11.8
Answer: x = 4/5
<u>Step-by-step explanation:</u>

Answer:
see below
Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9

Ok, great to have you! I will finally answer your question.
This seems to be a system of equations. I solve most of mine on Desmos.
Let us write two equations to model this:


We get the graph. Note the intersection at (26,33).
That means that route X is 26 miles long,and route Y is 33 miles long!.
Hope this helps.
Answer:
Step-by-step explanation:
f(x) = |2x−1|+3, reflected over the y-axis becomes
g(x) = |-2x−1|+3
We needed the point (0.5, 3) to go to the other side of the y-axis to get the point (-0.5, 3).
