Answer:
125.60
Step-by-step explanation:
the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).
hope that makes sense!!
Answer:
The exponential form of this would be (7x)^3/2
Step-by-step explanation:
The square root symbol is the same as writing raised to the 1/2. So we can rewrite the equation as:
[(7x)^1/2]^3
Then we can multiply the two exponents in this case giving us
(7x)^3/2
Answer:
$6,000
Step-by-step explanation:
The mean value of a sample is assumed to be the same as the mean of the population. The mean of a uniformly distributed variable between 0 and 160 is:

If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:

The mean aggregate maintenance cost is $6,000.
Either I've made a miscalculation... or none of these are correct...
1.7 in it's simplest form is 17/10.
So... neither A, B, C, or D is correct.
The correct answer is 43. hope i helped:)
