The slope of a linear regression is the rate of change of the line of the best fit
- The interpretation of the slope is that the wait time per staff is 1.62 minutes
- The slope value is realistic
The linear regression is given as:
y = -1.62x + 18
Where
- y represents the wait time
- x represents the number of staff
Using the above representations, the slope means that the wait time per staff is 1.62 minutes
Also, the slope value is realistic because time can be measured in decimals

Answer:
170
Step-by-step explanation:
A heptagon's internal angles add up to 900 degrees.
So:
(2x-13)+(3x-8)+(2x-3)+(2x-7)+(3x-1)+(2x+11)+(2x+9) = 900
16x - 12 = 900
16x = 912
x = 912/16
x = 57
So:
3x - 1 = 3 * 57 -1 = 170
Answer:
Domain: set of possible input values (x-values)
Range: set of output values (y-values)
The range for the function 
is:
(5, 8) is the vertex of the line
Because |x - 5| is absolute (so always positive) and it is multiplied by -2,
-2|x - 5| will always be negative unless x = 5 (when it will be zero). Therefore, the max y-value is 8.
However, your question actually asked what the function is when x = -5:
Answer: e) a pie graph showing the percentages of the whole
