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:
137°
Step-by-step explanation:
All angles in a triangle add up to 180° always.
Now imagine the two smaller shapes as a bigger triangle, CED. The measure of angle CED is 89°, and CDE is 48°. Do the math, and angle DCE is 43°.
But notice how the corresponding sides of the two smaller shapes are congruent. (CX=XE, and DY=YE) Meaning, the measure of angle C is equal to the measure of angle YXE.
We're almost there. CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180. 180-43 = 137°.
2 x - y = 2
- x + 5 y = 3 / *2
----------------------
2 x - y = 2
+
- 2 x + 10 y = 6
-----------------------
9 y = 8, y = 8/9
2 x - 8/9 = 2
2 x = 2 + 8 /9
2 x = 26/9
x = 13/9
( x, y ) = ( 13/9, 8/9 )
