Answer:
Step-by-step explanation:
The total number of ways of selecting 3 gems of any kind without replacement is 35 * 34 * 33 = 39270
Now selecting 2 gems from 25 is 25C2
25 C 2 = 25 * 24/2 = 300
Selecting one good gem is 10
Total selection = 300 * 10 = 3000
P(gems) = 3000 / 39270
P(gems) = 300/3927
P(gems) = 100/1309
1) + $12, since it is a profit
2) -1440 ft, since it is below the sea level
3) - 22°F, since it is below

Answer
t = 3n
Step-by-step explanation:
n and t are proportional so you know they will be on the opposite ends of the equal sign. Then you know that the items are purchased at the constant price of $3. That means you do the number of items times 3 to get the total cost.
Answer:
C. 54,000 m^2
Step-by-step explanation:
2 sides + 2 more sides
2(150x100) + 2(150x80)
30000 + 24000
54000m^2
