65 % is bigger than 16/25
2. You simplified parenthesis on both sides
3. Subtracted 14 from -25 on right side
6. Divided each side by 9
Answer:
1/9 use inverse.
Step-by-step explanation:
this is because you can use inversem since the word "of" indicates multiplication divide 1/27 and 1/3 and you get 1/3
Here is dependence between scores and x-values:

where
is the mean,
is standard deviation and i changes from 1 to 2.
1. When i=1,
then

2. When i=2,
then

Now solve the system of equations:


Subtract first equation from the second:

Then

Answer: the mean is 62, the standard deviation is 20.
