a contracter purchases 7 dozen pair of padded work glovs for $103.32. he incorrectly calculates the unit price at $14.76 what error did th contractor make
Answer:
The contractor made an error in calculating the unit price of the padded work gloves.
Step-by-step explanation:
To find the unit price of an item, we need to divide the total cost of the item by the number of units purchased. In this case, the contractor purchased 7 dozen pair of padded work gloves, which is equal to 7 x 12 = 84 pair of gloves. Therefore, the unit price of the padded work gloves is $103.32 / 84 pair = $1.23 per pair.
The contractor incorrectly calculated the unit price as $14.76, which is an error of $14.76 - $1.23 = $13.53. This error occurred because the contractor did not correctly take into account the number of units purchased when calculating the unit price.
Hope this helps:)

Calculate the residuals for your scatterplot in step 2d.
In statistics, a residual is defined as the difference between the predicted value of an outcome variable and the observed value of that variable. Residuals are used to evaluate how well a regression model fits the data.In order to calculate the residuals for a scatterplot, follow these steps:
Step 1: Plot the data on a scatterplot.
Step 2: Perform a regression analysis on the data to find the equation of the regression line. This equation should take the form y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.
Step 3: Using the equation of the regression line, calculate the predicted value of y for each data point in the scatterplot.
Step 4: Subtract each predicted value of y from the actual value of y for each data point in the scatterplot. This difference is the residual for that data point.
Step 5: Plot the residuals on a new scatterplot. The x-axis of this scatterplot should be the independent variable, and the y-axis should be the residual values.
Step6: This scatterplot is called a residual plot.Residuals are useful for identifying patterns in data that the regression model fails to capture. If the residuals are randomly scattered around the horizontal axis, then the regression model is a good fit for the data. If there are clear patterns in the residual plot, then the regression model may not be a good fit for the data and further analysis is required.

: What would be another way to calculate total interest rather than just adding up the individual interest amounts?
Answer:
Step-by-step explanation:
At the end of the loan/investment, you can take the accumulated value and subtract that from the principle/PV to get the total interest
The total interest earned can be determined by subtracting the principal from the future value of the loan.
There are two types of interests : simple interest and compound interest.
Compound interest is a type of interest in which the principal and interest already accumulated also earn an interest. While for simple interest it is only the principal that earns interest.
For example, if a loan of $4000 earns 10% interest compounded yearly, the future value of the the amount in 5 years is:
$4000 x (1.1)^5 = 6442.04
The interest earned over the 5 years can be determined by subtracting the cost of the loan from the future value of the investment
Interest = 6442.04 - $4000 = $2442.04
Another example, if a loan of $4000 earns 10% simple interest, the interest of the loan after 5 years is:
$4000 x 0.1 x 5 = $2000

How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
We are given that;
The point at (60, 55)
Now,
This means that customers who enter the special discount code can save $5 on this particular item.
In general, the point (x, y) on the graph represents an item with an original price of x dollars that is being sold at a sale price of y dollars. The graph is showing how the sale price of items changes as the original price increases.

10 workers can finish the job in 15 days. For the first 5 days, only 6 workers worked on the job. Then for the next 3 days 2 more workers joined them. To finish the job, 4 more workers joined
them. After how many days was the whole job done?
A. 8days
B. 12days
C. 16days
D. 18days
Answer:
C. 16 days
Step-by-step explanation:
Let´s say each worker does 1 ¨work¨, for each day, in order to complete the job in 15 days. That´s a total of 150 work.
If only 6 workers worked for the first 5 days, then we only do 30 by Day 5.
2 more workers join, so they do 8 work each day, 24 work in 3 days, 54 work by Day 8.
4 more workers join to complete the job, so we now do 12 work each day.
150 - 54 = 96
96 work is left to do, which would be done in 8 days by 12 workers.
8 days + 8 days = 16 days

-) Find the equation of the line that passes through (1,0) and (3,6).
The equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.
To find the equation of a line passing through two points, we can use the slope-intercept form of a linear equation: y = mx + b, where m is the slope of the line and b is the y-intercept.
Given points:
Point 1: (1, 0)
Point 2: (3, 6)
Step 1: Calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates:
m = (6 - 0) / (3 - 1)
m = 6 / 2
m = 3
Step 2: Substitute one of the given points and the slope into the equation y = mx + b to find the y-intercept (b).
Using Point 1 (1, 0):
0 = 3(1) + b
0 = 3 + b
b = -3
Step 3: Write the equation of the line using the slope (m) and the y-intercept (b):
y = 3x - 3
Therefore, the equation of the line that passes through the points (1, 0) and (3, 6) is y = 3x - 3.
This equation represents a line with a slope of 3, indicating that for every increase of 1 unit in the x-coordinate, the y-coordinate increases by 3 units. The y-intercept of -3 means that the line crosses the y-axis at the point (0, -3). By substituting any x-value into the equation, we can determine the corresponding y-value on the line.
Hence, the equation of the line passing through (1, 0) and (3, 6) is y = 3x - 3.

So, the mean number of points is 26 points
Jody's team scored 21, 25, 36, 16 and 32 points at the last five football games. What is the mean number of points Jody's team scored ?
Solution:-To find the mean, first of all we have to add up all the given points and then divide by how many number of points there are. So, there are total 5 points. Hence, we have to divide all the given points by 5.
So, Mean = \( \bf \frac{21 \: + \: 25 \: + \: 36 \: + \: 16 \: + \: 32}{5} \)

Hi there!
This is an example of supplementary angles, angles that sum up to 180° (they form a straight line).
Summing these two angles up equals 180°, so:
180° = (10x - 20)° + (6x + 8)°
We can drop the ° sign for ease of solving.
180 = 10x - 20 + 6x + 8
Combine like terms:
180 = (10x + 6x) - (20 + 8)
180 = 16x - 12
Add 12 to both sides:
192 = 16x
Divide both sides by 16:
192/16 = 16x/16
x = 12°

Given that the area immersed in the gap is changing as the coil enters the gap, what is the correct expression of Faraday's Law for this situation? That is, find the induced voltage as a function of the velocity of the glider, v, the flux density inside the magnetic gap, B, and other quantities you can measure from the video.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The induced emf is \(\epsilon = B * l * v\)
Step-by-step explanation:
Now assume that the coil is shaped as a rectangle with length \(l\) and width b
This implies that the area of the coil is \(A= l * b\)
Now when it enter into the uniform magnetic field the magnetic flux due to its movement as stated in the question is mathematically represented as
\(\phi = BA\)
=> \(\phi = B (l* b )\)
Now the induced emf is mathematically represented as
\(\epsilon = \frac{d\phi}{dt}\)
=> \(\epsilon = B * l [\frac{db}{dt} ]\)
The \(l\) is constant because as it glides to and from the magnetic field it is displaced along the horizontal plane while along the vertical plane it is constant
Here \(\frac{db}{dt} = v\)
Where is the velocity the glide (i.e the coil)
So
\(\epsilon = B * l * v\)
Based on the information given, it should be noted that the induced emf will be e = Blv.
According to Farday's law, the magnitude of the emf that's induced in a circuit will be proportional to the rate of change of the magnetic flux.
In this case, since the coil is rectangular shaped, the area will be the length multiplied by the width. When it enters the uniform magnetic field, the magnetic flux will be:
= B(l × b)
The induced emf will now be:
= B × l × v
= Blv
In conclusion, induced emf will be e = Blv.
