average mid-career salary of graduates, both in thousands of dollars. This model is accurate for annual tuition values between 10 thousand and 40 thousand dollars.
What is the slope of this linear model?
According to this model, what is the average salary for a graduate of a college or university where the annual tuition is $25,000?
$
The slope of the model is 0.83 and a graduate is expected to have an average salary of $20856
How to determine the slope of the model?The equation of the linear model is given as
y = 0.83x + 106
A linear equation is represented as
y = mx + c
Where m represents the slope
This means that when the equations y = mx + c and y = 0.83x + 106 are compared, we have:
m = 0.83
This means that the slope of the equation y = 0.83x + 106 is 0.83
Hence, the slope of the equation is 0.83
How to determine the average salary for a graduate?
Here, we have
Annual tuition = $25,000
This means that
x = 25,000
So, we have
y = 0.83 x 25000 + 106
Evaluate
y = 20856
Hence, the average salary for a graduate is $20856

The sum of two integers is 236. If one of the integers is-122, determine the other.
Answer: 114.
Step-by-step explanation: This would be an equation to set up. We have all three parts of the equation: The sum of the two numbers (236), one of the integers (122), and then an unknown number, (let's call it x). Since 236 is the total, 122 is one of the numbers, we need to look for the unknown number, x. Then we would set it up as 122+x=236. Subtract 122 to both sides, to get 114.

Hi, can you help me to solve this exercise please. If MK=6 ft, find the length “MKL to the nearest Tenth!
To find the arc length we need to know the angle subtended by the arc.
From the diagram we notice that angle MNK is of 180°.
We also notice that:
[tex]\begin{gathered} m\angle JNK+m\angle KNL=90 \\ 52+m\angle KNL=90 \\ m\angle KNL=90-52 \\ m\angle KNL=38 \end{gathered}[/tex]Then the angle subtended by the arc MKL is 218°.
Now that we know this we need to remember that the arc length is given by:
[tex]s=2\pi r(\frac{\theta}{360})[/tex]in this case the radius is 3 ft (The radius is half the diameter) then we have that:
[tex]\begin{gathered} s=2\pi(3)(\frac{218}{360}) \\ s=11.4 \end{gathered}[/tex]Therefore the arc length is 11.4 ft.

Given the pay rate and hours worked, determine the gross earnings, federal taxes (assuming 15% of gross earnings),
state taxes (assuming 5% of gross earnings), local taxes (assuming 2% of gross earnings), social security deduction
(assuming 7.65% of gross earnings), total deductions, and net pay.
pay rate= $8.50

Gross Earning is $323
Total deduction is $95.77 and Net pay is $227.23
In light of the hourly rate and salary (8.50, 38.0)
$8.50 an hour is the pay rate.
worked 38.0 hours in total.
38 hours total compensation (Gross Earning)=38×8.5 =$323
Now, we can see the total tax deduction.
Federal taxes (assumed to be 15% of gross income)
Therefore, Federal taxes = 0.15 x 323 = $48.45
State taxes (assuming 5% of gross earnings)
Therefore, State taxes = 0.05 x 323 = $16.15
Local taxes (assuming 2% of gross earnings)
Therefore, Local taxes = 0.02 x 323 = $6.46
Social security deduction (assuming 7.65% of gross earnings)
Therefore, Social security deduction = 0.0765 x 323 = $24.71
Total deduction = Federal taxes + State taxes + Local taxes + Social security deduction
Total deduction = 48.45+16.15+6.46+24.71 = $95.77
Net Pay = Gross Earning - Total deduction
Net Pay = $323 - $95.77 = $227.23
Thus, Gross Earning is $323, Total deduction is $95.77 and Net pay is $227.23

Devon owns a house cleaning company and has to give price quotes to potential customers. He figures out his price by assuming a $25 base charge and then adding $8 for each bathroom and $4 for each other room.
If he uses P to represent the price, B for bathroom, and R for other rooms, which of the following represents his price quote formula?
A P = 25 + 12(BR)
B P = 25 + 8B + 4R
C P = 25(4R + 8B)
D P = (4)(8)(R + B) + 25
Answer:
B P = 25 + 8B + 4R
Step-by-step explanation:
The price quote, P, will be equal to the total amount of charges. It’s given that there is a $25 base charge, so we can begin by writing the price quote as P = $25. To this base charge of $25, $8 per each bathroom, represented by the variable B, is added; our price quote is now P = $25 + $8B. Lastly, $4 per each other room, R, is added, and the actual price quote is P = $25 + $8B + $4R, or P = 25 + 8B + 4R.

What is a factor?The positive integers that can divide a number evenly are known as the factors in mathematics. Let's say we multiply two numbers to produce a result. The product's factors are the number that is multiplied. Each number has a self-referential element. There are several examples of factors in everyday life, such putting candies in a box, arranging numbers in a certain pattern, giving chocolates to kids, etc. We must apply the multiplication or division method in order to determine a number's factors.
The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.

PLEASE HELP- Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 25 gallons of fuel, the airplane weighs 2060 pounds. When carrying 45 gallons of fuel, it weights 2188 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?
The linear function which can be used to represent the situation is y = 6.4x + 1900 and airplane weight if it is carrying 60 gallons of fuel is 2,284 pounds
How to find linear functiony = mx + b
where,
x = the number of gallons and y = the weight of the aircraft in pounds.Now, we can use the two sets of data points given to us to first solve for the slope m as:
m = (2188 - 2060) / (45 - 25)
= 128 / 20
= 6.4
y - yo = m(x - xo)
y - 2060 = 6.4(x - 25)
y - 2060 = 6.4x - 160
y = 6.4x - 160 + 2060
y = 6.4x + 1900
if it is carrying 60 gallons of fuelx = 60
So,
y = 6.4x + 1900
y = 6.4(60) + 1900
y = 384 + 1900
y = 2,284 pounds
Therefore, the weight of the airplane if it is carrying 60 gallons of fuel is 2,284 pounds

Using it's concept, the probabilities are given as follows:
a) Both go off on schedule: 0.30 = 30%.
b) Both go off on schedule: 0.2 = 20%.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
From the text of the problem, the probability of A and not B is of 0.2, that is:
A x (1 - B) = 0.2.
We can multiply the probabilities as the events are independent.
In item a, the probability of neither is of 0.2, hence:
(1 - A) x (1 - B) = 0.2.
From the first equation, we have that:
A = 0.2/(1 - B).
From the second equation, we have that:
(1 - A) = 0.2/(1 - B).
Hence:
A = 1 - A
2A = 1
A = 0.5.
Then we can find B as follows:
(1 - A) x (1 - B) = 0.2.
1 - B = 0.2/0.5
1 - B = 0.4
B = 0.6.
The probability of both is:
A x B = 0.5 x 0.6 = 0.30 = 30%.
For item b, we consider that:
(1 - A) x B = 0.3.
We also have that:
A x (1 - B) = 0.2.
From the first equation:
B = 0.3/(1 - A).
Then, replacing on the second:
A x (1 - 0.3/(1 - A)) = 0.2
Which has a solution of:
A = 0.5, B = 0.4.
Hence the probability of both is:
0.4 x 0.5 = 0.2 = 20%.

1 pint = 2 cups
let cups of milk be x
1 pint of milk will give 2 cups
6 pints of milk will give x cups of milk
1 pint = 2cups
6 pints = x cups
Cross multiply
1 * x = 2 * 6
x = 12 cups
Therefore, Anna will need 12 cups of milk to produce a yoghurt.
