Answer:
(0, 3 ), (5, 0), (10, -3), (15, -6)
Step-by-step explanation:
3x − 5y = 15
-5y = 3x + 15
y = [tex]-\frac{3}{5} x + 3[/tex]
Point 1: (0, 3 )
y = -3/5(0) + 3
y = 0 + 3
y = 3
Validate:
3 = -3/5(0) + 3
3 = 3
Point 2: (5, 0)
y = -3/5(5) + 3
y = -3 + 3
y = 0
Validate:
0 = -3/5(5) + 3
0 = 0
Point 3: (10, -3)
y = -3/5(10) + 3
y = -6 + 3
y = -3
Validate:
-3 = -3/5(10) + 3
-3 = -3
Point 4: (15, -6)
y = -3/5(15) + 3
y = -9 + 3
y = -6
Validate:
-6 = -3/5(15) + 3
-6 = -6
Answer: For this problem, you cannot go over 10! so remember guys you can graph it however you want for example if you wanted to you could do -3/5(-2) + 3 for the first point but you would have to solve it. the next one would be maybe -3/5(-1) + 3 if you wanted to go up by plus one REMEMBER this is your OWN graph so do whichever number order you want it doesn't matter you can increase by 1 or 2 or 3 but the final point shouldn't be over ten or you will get the problem wrong. Good Luck I hope I get an A and I hope you guys get A's as well. Do ur absolute best on this
Allison can sew three scarves in 75 minutes. How many scarves can she sew in four hours?
Answer:
2.4
Step-by-step explanation:
75/3=25.
So she can do 1 scarf in 25mins
60/25=2.4
she can do 2.4 scarfs in one hour
Answer:
9.6 or 9 whole scarves
Step-by-step explanation:
You have to change the 4 hours into 240 minutes.
You can set it up as a proportion.
[tex]\frac{3}{75}[/tex] and [tex]\frac{x}{240}[/tex]
Then you need to set it up as:
75 x = 240 · 3
Then you get:
75 x = 720
Now you set it up as:
x = 720 ÷ 75
When you divide you get 9.6.
So, X = 9.6.
Allison can sew 9 whole scarves in four hours. The answer could also be 9.6 scarves. Not sure which one you need.

Imagine that owners of lemons are willing to sell for $2500 and owners of plums are willing to sell for $5000. Imagine that purchasers are willing to pay up to $2700 for a lemon and up to $6000 for a plum. Assume that sellers know what kind of car they have, but buyers can't tell. All buyers know is that one third of all used cars are lemons.
What is the maximum price that the buyers would be willing to pay for a car. (upto two decimal places)
The maximum price that buyers would be willing to pay for a car is $4900.
The maximum price that buyers would be willing to pay for a car can be determined by considering the expected value of the car. Since one third of all used cars are lemons, buyers would expect that there is a one-third chance of purchasing a lemon and a two-thirds chance of purchasing a plum.
Based on this information, we can calculate the expected value by considering the prices of lemons and plums and their respective probabilities.
The expected value is calculated as follows:
Expected value = (Probability of getting a lemon * Maximum price for a lemon) + (Probability of getting a plum * Maximum price for a plum)
In this case, the probability of getting a lemon is 1/3 and the probability of getting a plum is 2/3. The maximum price for a lemon is $2700 and the maximum price for a plum is $6000. Substituting these values into the formula, we can calculate the expected value:
Expected value = (1/3 * $2700) + (2/3 * $6000)
Simplifying the equation, we get:
Expected value = $900 + $4000
Expected value = $4900
Therefore, the maximum price that buyers would be willing to pay for a car is $4900. This price takes into account the probabilities of getting a lemon or a plum and the respective maximum prices buyers are willing to pay for each type of car. Buyers would consider this price as the maximum they are willing to pay, as it represents the expected value of the car considering the lemon-plum distribution and their respective preferences and valuations.

(PowerToys) PowerToys Inc. produces a small remote-controlled toy truck on a conveyor belt with nine stations. Each station has, under the current process layout, one worker assigned to it. Stations and processing times are summarized in the following table: a. What is the bottleneck in this process? b. What is the capacity, in toy trucks per hour, of the assembly line? c. What is the direct labor cost for the toy truck with the current process if each worker receives $15 /hour, expressed in dollars per toy truck? d. What would be the direct labor cost for the toy truck if work would be organized in a work cell, that is, one worker performs all tasks? Assume that the processing times would remain unchanged (i.e., there are no specialization gains). e. What is the utilization of the worker in station 2 ? Because of a drastically reduced forecast, the plant management has decided to cut staffing from nine to six workers per shift. Assume that (i) the nine tasks in the preceding table cannot be divided; (ii) the nine tasks are assigned to the six workers in the most efficient way possible; and (iii) if one worker is in charge of two tasks, the tasks have to be adjacent (i.e., one worker cannot work on tasks 1 and 3 ). f. How would you assign the nine tasks to the six workers? g. What is the new capacity of the line (in toy trucks per hour)?
The bottleneck in the process is Station 5, with a processing time of 8 minutes. The capacity of the assembly line is approximately 1.76 toy trucks per hour.
a. The bottleneck in this process is the station with the longest processing time. In this case, Station 5 has the longest processing time of 8 minutes. The bottleneck is the station that limits the overall capacity of the assembly line because it takes the longest time to complete its task.
b. To calculate the capacity of the assembly line, we need to determine the cycle time, which is the time it takes for one complete cycle of the assembly line. The cycle time is equal to the sum of the processing times at each station. In this case:
Cycle time = 1 + 2 + 3 + 4 + 8 + 6 + 5 + 3 + 2 = 34 minutes
To calculate the capacity in toy trucks per hour, we need to convert the cycle time from minutes to hours:
Capacity = 60 minutes / 34 minutes = 1.76 toy trucks per hour
c. The direct labor cost for the toy truck with the current process can be calculated by multiplying the number of workers assigned to each station by their hourly wage, and then dividing it by the number of toy trucks produced per hour. Since there is one worker per station and each worker receives $15 per hour, the direct labor cost per toy truck can be calculated as follows:
Direct labor cost = (Number of workers × Hourly wage) / Capacity
= (9 workers × $15/hour) / 1.76 toy trucks per hour
≈ $80.68 per toy truck
d. If the work were organized in a work cell, with one worker performing all tasks, the direct labor cost would remain the same. Each worker would still receive $15 per hour, regardless of the number of tasks they perform. There would be no specialization gains in this scenario, so the direct labor cost per toy truck would still be approximately $80.68.
e. To determine the utilization of the worker in station 2, we need to compare the processing time at that station to the cycle time of the assembly line. The processing time at station 2 is 2 minutes, and the cycle time is calculated as 34 minutes (as mentioned in point b).
Utilization = Processing time at station 2 / Cycle time
= 2 minutes / 34 minutes
≈ 0.059 or 5.9%
This means that the worker in station 2 is only utilized for about 5.9% of the cycle time, indicating that they spend most of their time waiting for the other stations to complete their tasks.
f. With the reduced staffing from nine to six workers per shift, the tasks should be assigned to the six workers in the most efficient way possible. One possible assignment could be as follows:
Worker 1: Stations 1 and 2
Worker 2: Stations 3 and 4
Worker 3: Stations 5 and 6
Worker 4: Stations 7 and 8
Worker 5: Station 9
Worker 6: No assigned task (idle)
g. To calculate the new capacity of the line with six workers, we need to determine the total processing time for the new assignment. The total processing time would be the sum of the processing times at each station assigned to a worker:
Total processing time = 1 + 2 + 6 + 5 + 3 + 2 = 19 minutes
The new capacity of the line would be the reciprocal of the total processing time:
Capacity = 60 minutes / 19 minutes = 3.16 toy trucks per hour
