B, because it says she has gone up 5 times Andre (a).
Answer: They would have to score an 88%
Step-by-step explanation:
1.) The mean of 84, 92, 83, and 78 is 337
2.) 337 divided by 4 is 84.25%
3.) If you add 88 to 337 and divide by 5, you get 85%
Answer: 43
Step-by-step explanation:
5-2+7x6-2
3+42-2
45-2
43
Value
Depreciation is defined as the reduction in value of an
asset over time. In this case, value reduction is due to wear and tear of an
equipment (bicycle).
a. The depreciation value would simply be the difference
in initial and salvage value divided by time in years.
Depreciation = (Initial value – Salvage value) / Number
of years
b. Substituting the given values into the equation where:
Initial value = $1200
Salvage value = $940
Number of years = 10 months = 10/12 years
Calculating:
Depreciation = ($1200 - $940) / (10/12 years)
Depreciation = $312 / year
or

To answer this item, we take the differential of the equation and equate to zero.
C(x) = 0.8x² - 256x + 25939
Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160.
Thus, the number of machine to be made in order to minimize the cost should be 160.
