200 – (74 + (720/9) + 44 + 16 x (4 + 6 – 8 x 2) - (42/2) + 70) – 2
200 – (74 + 80 + 44 + 16 x (-6) - 21 + 70) – 2
200 – (74 + 80 + 44 - 96 - 21 + 70) – 2
200 – 151 – 2

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:
C. Angles X and Z are supplementary
Step-by-step explanation:
A: This is true because in Angle Y, a right angle is shown. A right angle is worth 90°.
B: This is true because X, Y, and Z are supplementary (add to 180), and given that Angle Y is 90 degrees, 180 - 90. Thus, they're complementary.
C: This is false and the correct answer choice because Angle Y exists too. Angle X and Z, added together, would make 90 degrees, not 180.
D: This is true because Angles Y and Z are right next to each other, and that's what adjacent means.
Therefore, the answer is C.

Answer:
I think it's
2 HgO (s) → 2 Hg (l) + O2 (g)
Step-by-step explanation:
This is an oxidation-reduction (redox) reaction:
2 HgII + 4 e- → 2 Hg0
(reduction)
2 O-II - 4 e- → 2 O0
(oxidation)
