Answer:
subtract 27 from 85
Step-by-step explanation:
85
-27
———
58
7 cannot be subtracted from 5 so borrow a 10 to make it 7 subtracted from 15 and then the 8 tens becomes 7 tens so 7-2=5
58+27=85 to check your work
Cylinder Volume = PI * radius ^2 * height
52 = PI * radius ^2 * 4
radius ^2 = 52 / (PI * 4)
radius ^2 = 52 / 12.5663706144
radius ^ 2 = 4.1380285204
radius = 2.0342144726
OR a good approximation of the radius is 2 inches
Answer:
85
Step-by-step explanation:
A z-score of 1.25 means that the actual exam score is 1.25 standard deviations above the mean, and therefore the exam score we are looking for is: mean + 1.25 * SD = 75 + 1.25 * 8 = 85
