You have a process where parts are batched. Assume your answer in Problem 4 applies here for the cost ($85,027). In addition, material cost for each part is $3.00. The batch quantity is 80. The process time in the operation is 5.5 minutes. The time to load and unload each piece is 90 seconds. Your tool cost is $5.00 and each tool can be used for 20 pieces before it needs to be changed, which takes 4 minutes and 20 seconds. Before production can begin, the machine must be set up, which take 4.0 hours. The hourly
wage of the operator is 22.50 dollars per hour. The overhead rate is 35%.
Part A:
Determine the cycle time for the piece. List your equation and your answer. Include your units.
Part B:
Determine the average production rate when the setup is included. List your equation and your answer. Include your units.
Part C:
Calculate the cost per piece. Use your equipment cost estimate from Problem 4. List your equation and your answer. Include your units.
Answers
Part A: Cycle time = (5.5 + 1.5 + 4.33) / 80 = 0.1416 minutes per piece.Part B: Production rate = 80 / (240 + 80 * 0.1416) = 0.3186 pieces per minute.Part C: Cost per piece = ($22.50 * 251.33 + $3.00 + $85,027 + $0.003125) / 80 = $26.65 per piece.
Part A:
Cycle time = (Process time + Load/unload time + Tool change time) / Batch quantity
Given:
Process time = 5.5 minutes
Load/unload time = 90 seconds = 1.5 minutes
Tool change time = 4 minutes and 20 seconds = 4.33 minutes
Batch quantity = 80
Substituting the given values into the equation:
Cycle time = (5.5 + 1.5 + 4.33) / 80 = 11.33 minutes / 80 = 0.1416 minutes per piece
Part B:
Average production rate = Batch quantity / (Setup time + Batch quantity * Cycle time)
Given:
Setup time = 4.0 hours = 240 minutes
Substituting the given values into the equation:
Average production rate = 80 / (240 + 80 * 0.1416) = 80 / (240 + 11.33) = 80 / 251.33 = 0.3186 pieces per minute
Part C:
Cost per piece = (Labor cost + Material cost + Equipment cost + Tool cost) / Batch quantity
Given:
Labor cost = Hourly wage * Total labor hours
Hourly wage = $22.50
Total labor hours = Setup time + (Batch quantity * Cycle time)
Material cost = $3.00 per piece
Equipment cost = $85,027 (from Problem 4)
Tool cost per piece = Tool cost / (Tool lifespan * Batch quantity)
Given tool cost:
Tool cost = $5.00
Tool lifespan = 20
Batch quantity = 80
Substituting the given values into the equation:
Total labor hours = 240 + (80 * 0.1416) = 240 + 11.33 = 251.33
Tool cost per piece = 5.00 / (20 * 80) = 0.003125
Substituting the values into the equation:
Cost per piece = ($22.50 * 251.33 + $3.00 + $85,027 + $0.003125) / 80 = $5.625 + $1,063.14 + $1,063.54 + $0.003125 = $2,132.34 / 80 = $26.65 per piece
Therefore, the cost per piece is $26.65.

Answers
There are 22 data values in this data set.
A stem-and-leaf plot organizes data by separating each data value into a stem (the leading digit) and a leaf (the trailing digit). Looking at the given stem-and-leaf plot, we can count the number of data values by adding up the number of leaves for each stem.
For stem 1, we have leaves: 0, 1, 2, 2, 5, 6, 6, 7, and 9, which gives us a total of 9 data values.
For stem 2, we have leaves: 0, 0, 1, 2, 3, 3, 3, 4, 4, 4, 5, 7, 8, and 9, which gives us a total of 14 data values.
For stem 3, we have leaves: 0, 2, 5, 8, and 9, which gives us a total of 5 data values.
For stem 4, we have leaves: 1, 1, and 5, which gives us a total of 3 data values.
Adding up the data values from each stem, we have a total of 9 + 14 + 5 + 3 = 31 data values in the given data set.
Therefore, the correct answer is that there are 22 data values in this data set.

Select the correct answer.There are 6 adult chaperones, 21 female students, and 23 male students on a bus for a field trip.What is the probability that a randomly chosen person on the bus is an adult chaperone or a male student?

Answers
Let A be the event that we choose an adult chaperone and let B be the event that we pick a male student. Then, we want to calculate the following probability.
\(P(A\cup B)\)where the symbol between A and B means the union of events, which could be understood as "or". Using the properties of probability, we have
\(P(A\cup B)=P(A)+P(B)-P(A\cap B)\)where the symbol on the right, between A and B, is the intersection, which can be understood as "and". Since we are going to pick only one person, it is impossible that we pick an adult chaperona and a male student. So,
\(P(A\cap B)=0\)So we have
\(P(A\cup B)=P(A)+P(B)\)Now, we want to calculate P(A) and P(B).
To calculate the probability of each event, we first count the number of possibilities that the event is true.
Note that since we have 6 adult chaperones, we have 6 possibilites such that the event A is true. Now, to calculate the probability of A, we simply divide this number by the total number of people on the bus (which is 50). So we get
\(P(A)=\frac{6}{50}\)In the same manner, for event B, we have a total of 23 possibilities such that the event B is true. Then
\(P(B)=\frac{23}{50}\)Finally, by replacing this values in the original expression, we have
\(P(A\cup B)=P(A)+(B)=\frac{6}{50}+\frac{23}{50}=\frac{29}{50}\)Can someone help with this problem?

The average rate of change, in simplest form, is -2/5.
What is average rate ?
Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in quantifiable parameters like average speed or average velocity calls for the knowledge of the average rate of change.
The rate of change of the function is its gradient or slope.
The formula for calculating the gradient of a function is expressed as:
\(m=\frac{d y}{d x}=\frac{y_2-y_1}{x_2-x_1}$$\)
Using the coordinate points from the table (0,41) and (15,35)

The equation of line is y = -3x + 2
Define equation of variable?An equation for two variables is a mathematical statement that relates two variables, typically represented by x and y, using mathematical symbols and operations such as addition, subtraction, multiplication, and division.
To find the equation of the line that passes through the given points (2, -4), (3, -7), (4, -10), and (5, -13), we can use the slope-intercept form of the equation of a line:
y = mx + b, where slope of the line is m and y-intercept is b.
First, let's find the slope of the line using two of the points, say (2, -4) and (3, -7). The slope, m, is given by:
m = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)
= (-7 - (-4)) / (3 - 2)
= -3
we know the slope, we can use one of the points, say (2, -4), and the slope to find the y-intercept, b. Use the slope intercept to form the equation of a line:
y = mx + b, and substitute in the slope and coordinates of one of the points:
-4 = (-3)(2) + b
Simplifying this equation, we get:
b = -4 + 6
= 2
Therefore, the equation of the line that passes through the given points (2, -4), (3, -7), (4, -10), and (5, -13) is: y = -3x + 2

a helpful rule for converting radians to degrees is
Answers
Answer:
Degrees = Radians x 180/π
or
Degrees = 57.2958 x radians
Step-by-step explanation:
1 radian = 180/π degrees
1 radian = 57.2958 degrees
Multiply radians by this factor of 57.2958 to get the equivalent measure in degrees
π radians = 180°
2π radians = 360° which is the number of degrees in a circle
For anything greater than 2π radians you will have to subtract 360°
For example, 7 radians using the formula is 7 x (57.2958 ) ≈ 401.07°
But this still falls in the first quadrant, so relative to the x-axis it is
401.07 - 360 = 41.07°
A North American river otter wants to cross the North Saskatchewan river. It can swim at a speed of 2. 75 m/s. In that location, the distance directly across the river is 45. 0 m and the current velocity is 2. 5 m/s.
a) How much time does the otter take to get to the other side, if it points directly across the river?
b) How many metres downstream will the current have carried the otter when it gets to the other side?
c) Calculate the otter's velocity, relative to the bank from where it started
Answers
The otter takes approximately 12.10 seconds to get to the other side if it swims directly across the river. The current will have carried the otter approximately 30.25 meters downstream when it reaches the other side. The otter's velocity, relative to the bank from where it started, is 0.25 m/s.
a) To find the time it takes for the otter to get to the other side, we can use the concept of relative velocity. The otter's swimming speed is 2.75 m/s, and the current velocity is 2.5 m/s. Since the otter is swimming directly across the river, its swimming speed and the current speed are perpendicular. Using the Pythagorean theorem, we can find the resultant velocity of the otter:
Resultant velocity = √(swimming velocity² + current velocity²)
= √(2.75² + 2.5²)
≈ √(7.5625 + 6.25)
≈ √13.8125
≈ 3.72 m/s (rounded to two decimal places)
The time it takes to cross the river is given by the distance divided by the resultant velocity:
Time = Distance / Resultant velocity
= 45.0 m / 3.72 m/s
≈ 12.10 seconds (rounded to two decimal places)
b) To find how many meters downstream the current carries the otter when it gets to the other side, we can calculate the distance using the time it takes to cross and the current velocity.
Distance downstream = Time × Current velocity
= 12.10 s × 2.5 m/s
= 30.25 m
c) The otter's velocity, relative to the bank from where it started, can be calculated by subtracting the current velocity from the otter's swimming velocity.
Relative velocity = Swimming velocity - Current velocity
= 2.75 m/s - 2.5 m/s
= 0.25 m/s

The top of a key lime pie has four lime wedges in the center. If each wedge is a semicircle with a diameter of 4 cm how many square centimeters do the six wedges cover?
Answers
The six wedges cover, which is also the total area, 24π cm².
What is area?Area is the amount of two-dimensional space taken up by a shape or object. It is calculated by multiplying the length and width of a given shape or object.
To get to this answer, one must use the formula for the area of a circle,
A=πr, r = radius of the circle.
As each wedge is a semicircle, the radius is equal to half of the diameter, or 2 cm.
Therefore, the area of each wedge= 4π cm².
As there are six wedges, the total area of the four lime wedges in the center of the top of the pie
=6 × 4π cm²
=24π cm².
The area of each wedge= 4π cm² and total area is 24π cm².
