Answer:
Choice D. Total surface area = 8 + 8 + 4 + 4 + 2 + 2
Step-by-step explanation:
You want surface area of this rectangular prism
If you notice there are 6 faces of this prism
two faces with area 1*2 = 2
two faces with area 4*1 = 4
two faces with area 4*2 = 8
Total surface area = 8 + 8 + 4 + 4 + 2 + 2
The answer is the fourth option: rises 4 and then falls 14
One number is 6 and the other is 17. 6 x 2 is 12. 12 + 5 is 17. 17 + 6 is 23.
Answer:
data from minimum to maximum :
76 76 78 80 80 80 82 82 83 85 85 85 88 88 110
n= 15 , so the median is X8 = 82 minutes
mean =
(76+76+78+80+80+ 80 +82+ 82+ 83+ 85+ 85+ 85 +88 +88+ 110) / 15 = (1,258)/15 = 83.87 minutes
in order to get higher standard its better use mean as a typical value.
