Answer:
a. 20h + 8
Step-by-step explanation:
-2(-7h-4) + 6h = 14h + 8 + 6h = 20h + 8
The answer is $362.5
Here is why:
17.625 x 100 = 1762.5 (what was purchased)
21.25 x 100 = 2125 (what it was worth when sold)
2125 - 1726.5 = 362.5 (profit)

Answer:
437+36x≥500
Step-by-step explanation:
At x miles per day, Santiago will walk 36x miles in 36 days. He wants the total of that distance and the 437 miles he's already walked to be at least 500:
36x +437 ≥ 500 . . . . . . . matches the 3rd choice
We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
