Answer:
70.5
Step-by-step explanation:
Set of Data (Prioritized):
31, 43, 47, 58, 63, 68, <u>69, 72,</u> 77, 84, 84, 84, 94, 97
To find the median:
(69 + 72) ÷ 2
= 70.5
Therefore, the median is equal to 70.5.
It will take 5 stages to reach the surface.
-225/50=4.5 or what times 4.5 equals -225
Then the problem says to round up so 4.5 becomes 5.
2x + 2(x - 3) = 54
