Answer:
It is an unusual result contradicting the national survey.
Step-by-step explanation:
National survey showed 44% of college students who drink.
The professor's survey showed that 96/244 = 39% drink.
The professor's survey deviated from the national survey is 5% (44% - 39%) representing about 0.25% (5% squared) variance.
Standard deviation is the spread of a set of numbers from their mean. In other words, it measures how far an observed value is from the mean. It can be calculated by getting the square root of the variance.
The equation for working out the slope of a linear line is: 
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do 
, which is just 
when simplified.

The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Carson is going on a work trip. He will get reimbursed for his expenses for driving his own car.
He will get a flat rate of 30, plus $1.25 per mile (m) he drives.
The equation formed;
R = 30 + 1.25m
The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.
