Answer:
Using High and Low Method
Cost Miles
$
High 1,250 4,000
Low <u>(970) </u> <u>(3,000)</u>
<u> 280 </u> <u>1,000</u>
Variable cost per mile = $2,800/1,000
=$0.28 per mile
Explanation:
In this question, there is need to obtain the difference with the highest cost and lowest cost. We also need to calculate the difference between the highest miles and lowest miles. Finally, we will divide the difference in cost by the difference in miles in order to determine the variable cost per mile.
Answer:
Unitary cost= $38.2
Explanation:
Giving the following information:
Direct materials $9.40 per unit
Direct labor $19.40 per unit
Variable overhead $ 9.40 per unit
<u>The variable costing method incorporates all variable production costs (direct material, direct labor, and variable overhead) to calculate the unitary cost.</u>
UNitary cost= 9.4 + 19.4 + 9.4
Unitary cost= $38.2
Answer and Explanation:
As per the data given in the question,
Sum of the all mean value = 151
Average of the mean value = 151 ÷ 15 = 10.067
Similarly, Sum of the all given range = 151
Average of given range value = 151÷ 15 = 10.067
Control charts for the mean and the range, using the original 15 samples :
Upper control limit(UCL) - Lower control limit(LCL) for X bar is
= 10.067 + A2 × R bar
= 10.067 + (0.223 × 10.067)
= 12.31
LCL - UCL for X bar is
= 10.067 - A2 × R bar
= 10.067 -(0.223 × 10.067)
= 7.82
Set up the R-chart by specifying the center line and three-sigma control limits below :
UCLr = D4 × r
= 1.653 × 10.07
= 16.65
r = 10.067
= 10.07
LCLr = D3 × r
= 0.347 ×10.07
= 3.49
Let x be the number of children
Let y be the number of adults
Equation 1: x + y = 9
Equation 2: y = 9 - x
210x + 315y = 2205
210x + 315 (9-x) = 2205
210x + 2835 - 315x = 2205
2835 - 2205 = 315x - 210x
630 = 105x
630/105 = 105x/105
6 = x
There are 6 numbers of children.
To get the y, use the Equation 2: y = 9 - 6 ---> y = 3
Therefore there are 3 adults on the trip.

The probability that the mean price for a sample of 30 federal income tax returns is within $16 of the population mean is:
= 56%
Explanation:
a) Data and Calculations:
Population mean (preparation fee for 2017 federal income tax returns) = $273
Population standard deviation of preparation fees = $100
Mean price for a sample of 30 federal income tax returns = $257 (which is within $16 of the population mean)
z = (x-μ)/σ
z = standard score
x = observed value
μ = mean of the sample
σ = standard deviation of the sample
Z = ($273 - $257)/$100
= 0.16
Using the z-table
P = 0.5636
