Tekan-Tekan Sdn. Bhd. has order for 200 Model AS-120 calculator for delivery on day 200. The calculator consists of three parts. Components 2 and 3 form subassembly 1 . Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Answers
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

A firm requires an investment of $36,000 and borrows $12,000 at 9%. If the return on equity is 20%, what is the firm's pretax WACC? Select one: a. 8.2% b. 19.6% c. 16.3% d. 22.9%
Answers
First, let's calculate the after-tax cost of debt:
After-tax cost of debt = pre-tax cost of debt x (1 - tax rate)
Since the tax rate is not given in the question, we will assume it to be 30% (a common corporate tax rate).
After-tax cost of debt = 9% x (1 - 0.3) = 6.3%
Next, we need to find the cost of equity. The cost of equity can be calculated using the Capital Asset Pricing Model (CAPM):
Cost of equity = Risk-free rate + Beta x Market risk premium
The risk-free rate is typically the yield on a long-term government bond, which is not given in the question. Let's assume it to be 3%.
The beta is also not given in the question. Let's assume it to be 1.2, which is a typical beta for a moderately risky stock.
The market risk premium is the excess return that investors expect to receive for holding a risky asset. Let's assume it to be 8%.
Cost of equity = 3% + 1.2 x 8% = 12.6%
Now we can calculate the WACC as follows:
WACC = (Equity / Total capital) x Cost of equity + (Debt / Total capital) x After-tax cost of debt
Total capital = Equity + Debt = $36,000 + $12,000 = $48,000
Equity / Total capital = $36,000 / $48,000 = 0.75
Debt / Total capital = $12,000 / $48,000 = 0.25
WACC = 0.75 x 12.6% + 0.25 x 6.3% = 9.9%
Therefore, the firm's pretax WACC is 9.9%. None of the given answer options matches this result, so the correct answer is not provided.

How can you solve a linear system (Ax=b) using inverse matrices?
Answers
To solve for x, we just need to compute the inverse of A (if it exists) and multiply it by b. If A is invertible, then this method will give us the unique solution to the linear system Ax=b.
To solve a linear system of the form Ax=b using inverse matrices, we can first find the inverse of matrix A (if it exists) and then multiply both sides of the equation by \(A^-1\), giving us:
\(A^-1Ax = A^-1b\)
Since\(A^-1A\) is the identity matrix I, we can simplify the left-hand side to just x:
\(x = A^-1b\)
However, it's worth noting that computing the inverse of a matrix can be computationally expensive, particularly for large matrices.
So, while using inverse matrices can be a useful technique for solving small systems, it may not be the most efficient approach for larger systems. In those cases, other techniques such as Gaussian elimination or LU decomposition may be more appropriate.

what's the probability you don't roll doubles on your first roll, then roll doubles on your second roll?
Answers
We have a 1/6 chance of rolling doubles on the first roll. The odds of rolling a double on the second turn but not the first are (5/6) x (1/6) = 5/36.
So we have a total of 36 outcomes over here. So we have 36 possibilities, and if we simplify this, 6/36 is 1/6. So the chance of rolling doubles on two six-sided dice numbered 1 to 6 is 1/6.
The odds of rolling a double on the second turn but not the first are (5/6) x (1/6) = 5/36.

For what value of k, the following system of equations kx+2y=3, 3x+6y=10 has a unique solution ?
Answers
The given system of equations to have a Unique solution, the value of k must be any real number except 1 (k ≠ 1).
The value of k for which the given system of equations has a unique solution, we can use the concept of determinants. The system of equations is as follows:
kx + 2y = 3 -- (1)
3x + 6y = 10 -- (2)
To have a unique solution, the determinant of the coefficients of x and y must not be zero.
The determinant of the coefficient matrix for the system is:
D = | k 2 |
| 3 6 |
By calculating the determinant, we have:
D = (k * 6) - (2 * 3)
D = 6k - 6
For the system to have a unique solution, the determinant D must not equal zero.
6k - 6 ≠ 0
Simplifying the inequality:
6k ≠ 6
Dividing both sides by 6:
k ≠ 1
Therefore, for the given system of equations to have a unique solution, the value of k must be any real number except 1 (k ≠ 1).
In other words, if k is not equal to 1, the system of equations will have a unique solution. If k is equal to 1, the system will either have infinitely many solutions or no solution.

you are interested in estimating the the mean age of the citizens living in your community. in order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. if you want your sample estimate to be within 3 years of the actual mean with a confidence level of 97%, how many citizens should be included in your sample? assume that the standard deviation of the ages of all the citizens in this community is 22 years.
Answers
To ensure that the sample estimate of the mean age is within 3 years of the actual mean with a confidence level of 97%, approximately 547 citizens should be included in the sample.
To determine the sample size, we can use the formula for the margin of error in a confidence interval:
Margin of Error = Z * (Standard Deviation / √n)
Where Z represents the critical value corresponding to the desired confidence level. For a 97% confidence level, the critical value Z is approximately 2.17. The standard deviation is given as 22 years.
Rearranging the formula to solve for the sample size, we have:
n = (Z^2 * Standard Deviation^2) / Margin of Error^2
Plugging in the values, we get:
n = (2.17^2 * 22^2) / 3^2 ≈ 546.93
Since we can't have a fraction of a citizen, we round up to the nearest whole number. Therefore, a sample size of approximately 547 citizens should be included to estimate the mean age of the community with a margin of error of 3 years and a confidence level of 97%.

The speed of sound is approximately 720 miles per hour at sea level. At this rate, how many feet does it travel in 20 seconds? Use 1 mile=5280 feet.
Answers
Answer: 21120 feet.
Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.
The distance travelled by sound in 20 seconds is 21120 feet.
What is speed?In unit time the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 720 miles per hour.
According to given condition,
1 hour = 720 miles
Since, 1 hour = 60 minutes
60 minutes = 720 miles
1 minute = 12 miles.
1 minute = 60 seconds
60 second = 12 miles
1 second = 12 / 60 = 1/5 miles
20 second = 20 / 5 = 4 miles
According to given condition,
1 mile = 5280 feet
Therefore,
20 second = 5280 x 4 = 21120 feet
The distance travelled in 20 seconds is 21120 feet.
