Answer:
Step-by-step explanation:
Since your population are the students in math class, you can use the z-score formula 
in order to comparing the two math test scores. Where 
is the mean for the class, 
is the standars deviation and x is Mary score.
For the first test 
, so ,
.
For the second test 
, so ,
Mary do better in the second test, relative to the rest of the class (because 
, it means the second score is nearer to the mean score of the class than the first one )
solution,
slope(m) = y2-y1/ x2-x1
= 4+7/1+3
=11/4
I hope this is correct, the formula can be wrong so pls double check if u have formula.
8 s -11 s + 6= - 3 s + 6=
= 3( - s +2)
12/6 can be written as 2 because 6 can go into 12 two times.
Answer:
The Proof for 
is below.
Step-by-step explanation:
To Prove:
Proof:
We know law of indices
Therefore,
Step 1: Applying law of indices
Step 2: Taking common 
we get
Step 3: 
so add 5 + 1 we get
Step 4: Cancel 6 from both denominator and numerator we get
...That is Divisible by 6 Proved
