Answer:
The answer is 18,019 days.
Step-by-step explanation:
Answer:
a) 0.4121
b) $588
Step-by-step explanation:
Mean μ = $633
Standard deviation σ = $45.
Required:
a. If $646 is budgeted for next week, what is the probability that the actual costs will exceed the budgeted amount?
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
For x = $646
z = 646 - 633/45
z = 0.22222
Probability value from Z-Table:
P(x<646) = 0.58793
P(x>646) = 1 - P(x<646) = 0.41207
≈ 0.4121
b. How much should be budgeted for weekly repairs, cleaning, and maintenance so that the probability that the budgeted amount will be exceeded in a given week is only 0.16? (Round your answer to the nearest dollar.)
Converting 0.16 to percentage = 0.16 × 100% = 16%
The z score of 16%
= -0.994
We are to find x
Using z score formula
z = (x-μ)/σ
-0.994 = x - 633/45
Cross Multiply
-0.994 × 45 = x - 633
-44.73 = x - 633
x = -44.73 + 633
x = $588.27
Approximately to the nearest dollar, the amount should be budgeted for weekly repairs, cleaning, and maintenance so that the probability that the budgeted amount will be exceeded in a given week is only 0.16
is $588
Bottom Side Surface Area:
(24 inches + 24 inches + 24 inches) * (30 inches)
= 72 inches * 30 inches
= 2160 inches squared
--------
Top Side Surface Area:
24 inches * 30 inches
= 720 inches squared
--------
Length of the diagonal (D) which needs to be measured:
*Use Pythaogras's theorem...
24^2 + 10^2 = D^2
D=√(24^2+10^2)
D=26 inches
------------
Measure the surface area of the two ramps:
26 inches * 30 inches * 2
= 1560 inches squared
-----------
Total surface area:
2160 inches squared + 720 inches squared + 1560 inches squared
= 4440 inches squared
---------
Answer:
4440 square inches
To answer the question above, directly substitute the given price which is $100 to all the x's of the given equation,
C = 0.765x + 0.06 (0.765x)
C = (0.765) ($100) + 0.06 (0.765) ($100) = 81.09
Thus, Chris would have to pay only $81.09.
