Step-by-step explanation:
Note: The data in the question are merged. The data are therefore sorted and the whole question is represented before answering the question. Please, see the attached pdf file for the sorted data and the represented question.
The explanation of the answer is now given as follows:
Marginal cost refers to the cost incurred in order to produce one more unit of a product.
Therefore, marginal cost is the change in the total cost that is caused by a one-unit increase in the quantity of a commodity that is produced.
From the table in the question, the marginal cost at q = 108 can be calculated as follows:
Change in total quantity at 180 cases = 108 - Number of cases immediately before 108 = 180 - 104 = 4
Change in total cost at 180 cases = Total cost at 108 cases - Total cost immediately before 108 cases = 1990 - 1920 = 70
Marginal cost at 108 cases = Change in total cost at 180 cases / Change in total quantity at 180 cases = 70 / 4 = 17.50 per case
Therefore, the correct option is c) $17.50/case.
The common ratio in a geometric series is 0.50.50, point, 5 and the first term is 256.

Answer:
504
Step-by-step explanation:
I think the correct question is like:The common ratio in a geometric series is 0.50 ( point 5) and the first term is 256.
Find the sum of the first 6 terms in the series.
If it's right, then
Sₙ = (a₁ × (1 - rⁿ)) / (1 - r)
S₆ = (256 × ( 1 - 0.5⁶)) / (1 - 0.5)
= (256 × 0.984375) / 0.5
= 504

find the length of segment AB
Answer:
AB = 10.77 units
Step-by-step explanation:
If the extreme ends of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2, y_2)[/tex].
Then the length of the segment joining these extreme ends will be,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
If the extreme ends of the line segment AB are A(-3, 1) and (7, 5).
Measure of AB = [tex]\sqrt{(7+3)^2+(5-1)^2}[/tex]
AB = [tex]\sqrt{100+16}[/tex]
AB = [tex]\sqrt{116}[/tex]
AB = 10.77 units
Therefore, length of the segment AB will be 10.77 units.
The area of a rectangular piece of land J is 220 square metres.Its width is 12.5.what is the perimeter of the land ?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ {60.2 \: m}}}}}}[/tex]
Step-by-step explanation:
Given,
Area of rectangular piece of land ( l ) = 220 m²
Width ( w ) = 12.5 m
Finding length of the rectangular piece of land
[tex] \boxed{ \sf{area \: of \: rectangle = l \times w}}[/tex]
plug the values
⇒[tex] \sf{220 = l \times 12.5}[/tex]
Swap the sides of the equation
⇒[tex] \sf{12.5 \: l = 220}[/tex]
Divide both sides of the equation by 12.5
⇒[tex] \sf{ \frac{12.5 \: l}{12.5} = \frac{220}{12.5} }[/tex]
Calculate
⇒[tex] \sf{l = 17.6 \: m}[/tex]
Length of rectangular piece of land ( l )= 17.6 m
Finding perimeter of rectangular piece of land
[tex] \boxed{ \sf{perimeter \: of \: rectangle = 2(l + b)}}[/tex]
plug the values of length and breadth
⇒[tex] \sf{2(17.6 + 12.5) }[/tex]
Add the numbers
⇒[tex] \sf{2 \times 30.1}[/tex]
Multiply the numbers
⇒[tex] \sf{60.2 \: m}[/tex]
Therefore, Perimeter of rectangular piece of land is 60.2 m

Enter the correct value so that each expression is a perfect square trinomial
Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3). [tex]x^{2}+\frac{1}{2}x+a^2[/tex]
[tex]x^{2}+2(\frac{1}{4})x+a^2[/tex]
To make this expression a perfect square,
a² = [tex](\frac{1}{4})^2[/tex]
[tex]x^{2}+2(\frac{1}{4})x+(\frac{1}{4})^2[/tex] = [tex](x+\frac{1}{4})^2[/tex]
Therefore, the missing number will be [tex]\frac{1}{16}[/tex].

The revenue, in dollars, of a company that produces video game systems can be modeled by the expression 5x2 + 2x – 80. The cost, in dollars, of producing the video game systems can be modeled by 5x2 – x + 100, where x is the number of video game systems sold. If profit is the difference between the revenue and the cost, what expression represents the profit?
Answer: 3x-180
Step-by-step explanation:
Given: Expression for Revenue = [tex]5x^2 + 2x - 80[/tex]
Expression for Cost = [tex]5x^2- x + 100[/tex]
If profit is the difference between the revenue and the cost then the expression for profit will be:
Profit = Revenue - cost
[tex]=5x^2 + 2x - 80-(5x^2- x + 100)\\\\=5x^2 + 2x - 80-5x^2+x-100\ \ [\text{Multiply ' - ' sign inside the bracket}]\\\\=2x+x-80-100\\\\=3x-180[/tex]
Hence, the expression represents the profit is 3x-180 .

We are trying to come up with a regression model that predicts university GPA. Is high school GPA a significant predictor for university GPA?
Answer:
No.
Step-by-step explanation:
High school GPA is not a significant predictor of University GPA.
The Grade Point Average obtained at the end of high school education has almost nothing (in my opinion, it has nothing to do with) to do with grades that the scholar will obtain in college. Many scholars find it difficult adjusting to the social and academic life demands of tertiary institution.
A good predictor for university Grade Point Average would be:
The CGPA (Cumulative Grade Point Average) obtained by the student(s) in each year/session/level/part in the university.
This will be a significant predictor for university GPA.

To find:
How to transform the graph of f.
Total reimbursement for a trip of 95 miles?
Solution:
[tex]f(x) = 0.45m +5[/tex] can also be written as:
[tex]y = 0.45m +5[/tex]
It is nothing but slope intercept form, comparing with [tex]Y = M X+ C[/tex]
M is the slope and C is the y intercept.
Slope of the graph is 0.45.
Y intercept is 5.
After change in the function, first of all add $5.
[tex]0.45m + 5+5 = 0.45m+10[/tex]
Now, multiply with 1.25
Resulting function becomes:
[tex]f(x) =1.25\times (0.45m+10)\\\Rightarrow f(x) =0.5625m+12.5[/tex]
Kindly refer to the attached image for the graph of the two functions.
Now, the slope becomes 0.5625 and y intercept becomes 12.5. This is the transformation.
To find the reimbursement for a trip of 95 miles:
Put m = 95
[tex]f(95) =0.5625\times 95+12.5 = \bold{\$65.9375 }[/tex]
Find the interval in which f(x)=sinx−cosx is increasing or decreasing?
Answer:
There is no short answer.
Step-by-step explanation:
To find to intervals which f(x) increases or decreases, we first need to find it's derivative.
[tex]f(x) = sinx - cosx\\f'(x) = cosx - (-sinx) = cosx + sinx[/tex]
The function is increasing when it's value is > 0 and decreasing when it's value is < 0.
If we take a look at this graph, cosx+sinx is positive when they are both positive or when cosx is greater then sinx on the negative part.

Answer/Step-by-step explanation:
Given:
Data set for sandwich calories=> 242, 290, 290, 280, 390, 350
Mean: the mean is given as sum of all values in the data set ÷ total no. of data set given
[tex] \frac{242 + 290 + 290 + 280 + 390 + 350}{6} = \frac{1,842}{6} = 307 [/tex]
Mean Absolute Value:
Step 1: find the absolute value of the difference between each value and the mean
|242 - 307| = 65
|290 - 307| = 17
|290 - 307| = 17
|280 - 307| = 27
|390 - 307| = 83
|350 - 307| = 43
Step 2: find the sum of all values gotten in step 1
65 + 17 + 17 + 27 + 83 + 43 = 252
Step 3: divide the result you get in step 2 by 6 to get the M.A.D
[tex] M.A.D = \frac{252}{6} = 42 [/tex]
The Mean Absolute Value represents or gives us an idea how spread the data set for the number of sandwich calories are.
Thus, averagely, the number of calories of sandwich at the restaurant are far from the mean caloric value by 42 calories.

Which of these pairs of functions are inverse functions?
Answer:
see below
Step-by-step explanation:
You can attack this several ways. One is to work through f(g(x)) in each case and see if the result is x.
Another is to use a graphing calculator to evaluate y=f(g(x)) to see if the result is the line y=x.
Yet another way to work this is to pick a convenient value for x and evaluate f(g(x)) or g(f(x)). Here, we'll show this last case.
A: f(1) = 2^0 +1 = 2; g(2) = log2(2-1) -1 = -1 . . . . g(f(1)) = -1, not 1 ⇒ not inverses
B: f(2) = 1/2(ln(1) -1) = -1/2; g(-1/2) = 2e^(0) = 2 . . . g(f(2)) = 2 ⇒ inverses
C: f(e) = 4ln(e^2)/e^2 = 8/e^2; g(8/e^2) = e^1 = e . . . g(f(e)) = e ⇒ inverses
D: f(10) = 10^0-10 = -9; g(-9) = log(1) -10 = -10 . . . g(f(10)) = -10, not 10
⇒ not inverses

A painter rented a wallpaper steamer at 9 a.m. and returned it at 4 p.m. He paid a total of $28.84. What was the rental cost per hour?
Greetings,
I hope you and your family are staying safe and healthy!
Answer: $4.12 per hour
Step-by-step explanation:
So, 9am to 4pm is 7 hours
Why? Because you go from 10am, 11am, 12pm, 1pm, 2pm, 3pm, and 4pm.
So now all we have to do is to divide the amount he paid by the number of hours.
Like this:
[tex]\frac{28.84}{7} = 4.12[/tex]

Answer:
[tex] y = 178.3 ft [/tex]
Step-by-step explanation:
y is opposite to the reference angle, 27°.
350 ft is adjacent to the reference angle, therefore:
[tex] tan(27) = \frac{y}{350} [/tex]
Multiply both sides by 350
[tex] tan(27)*350 = \frac{y}{350}*350 [/tex]

PRACTICE ANOTHER Calculate the standard deviation σ of X for the probability distribution. (Round your answer to two decimal places.) σ = (No Response) 1.00
Complete Question
The complete question is shown on the first uploaded image
Answer:
The standard deviation is [tex]\sigma = 1.17[/tex]
Step-by-step explanation:
From the question we are told that
The data is
x 1 2 3 4
P(X = x) 0.2 0.2 0.2 0.4
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ \sum x^2 P(x) - (\sum x P(x))^2 }[/tex]
Here [tex]x^2 = 1^2 \ \ 2^2 \ \ 3 ^2 \ \ 4^2[/tex]
=> [tex]x^2 = 1 \ \ 4 \ \ 9\ 16 \[/tex]
[tex]\sum x^2 * P(x) = (1 * 0.2) + (4 * 0.2 ) + (9 * 0.2 ) + (16 * 0.2 )[/tex]
[tex]\sum x^2 * P(x) = 9.4[/tex]
[tex]\sum x P(x) = (1 *0.2) + (2*0.2) + (3 * 0.2) + (4 * 0.2)[/tex]
[tex]\sum x P(x) = 2.8[/tex]
So
[tex]\sigma = \sqrt{ 9.2 - (2.8)^2 }[/tex]
[tex]\sigma = 1.17[/tex]

The value of the flow rate in cubic feet per hour is 0.04.
What is the rate of flow?The rate of the flow of the fluid is defined as the volume of the fluid flowing through the cross-section per unit of time. The unit of the flow rate is cubic feet per hour or cubic meter per hour etc.
Given that water flows through a pipe at a rate of 6300 liters every 8.5 months. Then the flow rate in cubic feet per hour will be calculated as below:-
1 litre = 0.0353 cubic feet
6300 litres = 6300 x 0.0353
6300 litres = 222.4 cubic feet
1 month = 730 hours
8.5 months = 6205 hours
The rate of flow in cubic per hour will be:-
Rate of flow = 222.4 / 6205 = 0.04 cubic feet per hour
Therefore, the value of the flow rate in cubic feet per hour is 0.04.
