one hundred units of part a are to be processed on a work center. the setup time is 2 hours and the run time per piece is 10 minutes. the total standard time will be
The total standard time required to processed for one hundred units as per given setup and run time is equal to 1120minutes.
As given in the question,
Number of units to be processed = One hundred units
Conversion used:
1 hour = 60 minutes
Time required for setup = 2 hours
= 2 ( 60) minutes)
= 120 minutes
Run time per piece = 10 minutes
⇒ Run time required for 100 units = 100 × 10
= 1000 minutes
Total standard time for 100 units is equal to
= Run time for 100 units + set time
= 1000 + 120
= 1120 minutes
Therefore, the total standard time required to processed 100 units is equal to 1120 minutes.

Dominic solves the equation 3(x - 5) + 2x = 0 for x using the steps below. drag and drop the correct values to make his work and answer correct
Answer:
x = 3
Step-by-step explanation:
First, distribute the 3.
3(x - 5) + 2x = 0
3x - 15 + 2x = 0
Next, combine the x's.
(3x + 2x) - 15 = 0
5x - 15 = 0
Then, add 15 to both sides.
5x = 15
Finally, divide by 5 on both sides.
x = 3
In a math class with 28 students, a test was given the same day that an assignment
was due. There were 20 students who passed the test and 19 students who completed
the assignment. There were 16 students who passed the test and also completed the
assignment. What is the probability that a student passed the test given that they
completed the homework?
The phrase "given that they completed the homework" indicates that we're only looking at the students who completed the homework. We're ignoring those students who didn't complete the homework.
Of the 19 students who completed the homework, 16 of those passed the test.
This gives us the fraction 16/19 which is about 0.842105263157895 or about 84.2%.
That's your probability that a student passed the test given that they completed the homework.
Solve the system of linear equations by elimination.
4x + 3y = -5
-x+3y=-10
solution:
Answer:
x=1, y=-3
Step-by-step explanation:
We first see there is a 3y in both equations. We can completely eliminate the y term by subtracting the equations.[tex](4x+3y=-5)-(-x+3y=-10)[/tex]. This gives us (4x--x)=(-5--10), which is 5x = 5. So, x = 1.
Now we can plug this value in to solve for y. Let's plug it in to [tex]-x+3y=-10[/tex]. We get [tex]-1 + 3y=-10[/tex], so 3y = -9 and y = -3. Hope this helps!

Answer:
A. Linear
B. Non-linear
C. Linear
Step-by-step explanation:
A linear line has a consistent slope either going down (negative) or going up (positive.)
A. The x values are increasing by a constant rate of 1, and the y values are decreasing at a constant rate of 1. Therefore it is a linear relation.
B. The x values are increasing by a constant rate of 1, but the y-value repeats itself twice in the second and third column. Therefore it does not have a consistent slope and is not a linear relation.
C. The x values are increasing by a constant rate of 1, and the y- values increase by a constant rate of 2 except in column 4 making it a non-linear relation.
Sir Ronald Fisher's F-distribution is used in many statistical tests. Which one of the following uses the F-distribution for their test statistic?
a. To compare several population means simultaneously
b. Comparison of samples to see if they came from populations with the same proportions.
c. Test of two samples to see if they are from populations with the same median
The one which uses Sir Ronald Fisher's F-distribution for the test statistic is to compare several population means simultaneously.
What is the F-distribution?The F-distribution was developed by Sir Ronald Fisher to study the behavior of two variances from random samples taken from two independent normal populations. The F-distribution allows us to use a F statistic to compare two populations.
The F-distribution is also known as a right-skewed distribution used commonly in another statistical test called an Analysis of Variance (ANOVA). For ANOVA tests we can use the F-distribution to check whether the variance among the means of two populations significantly differ. The F-distribution can also be used in regression analysis to compare the fit of different models.

In a tsunami, the wave speeds (in meters per second) can be modeled by s(d)=√9.8d, where d is the depth (in meters) of the water. Estimate the depth of the water when the wave speed is 200 meters per second
The depth of the water when the wave speed is 200 meters per second is 4081.63m
What is Speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
Given,
In a tsunami, the wave speeds (in meters per second) can be modeled by s(d)=√9.8d,
Where d is the depth
We need to find the depth when speed is 200 meters per second
s(d)=√9.8d,
200=√9.8d,
Square on both sides
40000=9.8d
Now divide both sides by 9.8
d=4081.63m

Step-by-step explanation:
the average of a list of 4 numbers is 92.0 . a new list of 4 numbers has the same first 3 numbers as the original list, but the fourth number in the original list is 40 , and the fourth number in the new list is 48 . what is the average of this new list of numbers?
The average of the new list of 4 numbers is 94.
If the average of the original list of 4 numbers is 90, then the sum of these 4 numbers is:
4 x 90 = 360
If the 4th number in the original list is 80, then the sum of the first 3 numbers in the original list is:
360 - 80 = 280
If the first 3 numbers in the new list are the same as in the original list then the sum of these new first 3 numbers is also:
280
If the 4th number in the new list is 96 then the sum of the 4 numbers in the new list is:
280 + 96 = 376
Therefore, the average of the new list of 4 numbers is:
376 / 4 = 94

Answer:
• Area of parallelogram = 270 in.²
• Area of square = 225 in.²
• Area of composite figure = 495 in.²
Step-by-step explanation:
We are given a composite figure made up of a parallelogram and a square and told to find its area.
To do this, we are told first to find the area of the parallelogram. The formula for the area of a parallelogram is:
[tex]\boxed{\mathrm{Area \ of \ parallelogram = base \times height}}[/tex].
From the figure, we can see that, for the parallelogram, height = 18 in. and base = 15 in. (since opposite sides of a parallelogram are equal).
Using this information, we can calculate the area of the parallelogram:
Area = base × height
= 15 in. × 18 in.
= 270 in.²
Next, we have to find the area of the square using the formula:
[tex]\boxed{\mathrm{Area \ of \ square = side \times side}}[/tex].
From the figure, we can see that the length of a side of the square is 15 in.
Therefore, using the formula above, we can calculate the area of the square:
Area = side × side
= 15 in. × 15 in.
= 225 in.²
Now that we know the respective areas of the two shapes that make up the composite shape, we simply have to add the areas together:
Area of composite figure = 270 in² + 225 in²
= 495 in.²
