D.The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cots at No Ruff Stuff Animal Hospital is

Answer:
C. 5 times the MAD
Step-by-step explanation:
The difference between the mean cost to treat dogs at No Ruff Stuff Animal Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is about 5 times the MAD. This is a large difference.
The correct option is C.
What is the mean?In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).
Given:
The mean cost to treat dogs at No Ruff Stuff Animal Hospital is $224.65.
And MAD = $20.52
The mean cost to treat cats at No Ruff Stuff Animal Hospital is $124.84.
And MAD = 19.75.
The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is,
= 224.65 - 124.84.
= 99.81
= 5 x 19.75
Therefore, the difference is 5 times MAD.

On a quiz there are four multiple-choice questions worth 3 points each and two true/false questions
worth 1 point each. Each multiple-choice question has five possible choices. If a student randomly
guesses on each question, what is the expected value of the student's score on the test?
a 1.8
b 5.4
c 3.4.
d 2.8
Answer:
C. 3.4
Step-by-step explanation:
We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.
Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.
Expected value, denoted by E(x), has the formula:
E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct
E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.
The answer is thus C.

How to find the function which was used to make 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.
Hence, the equation of this graph would be (x − 5)^2 = -8(y + 4).
So option D is correct.

The volume of the trapezoidal prism comes to be 312 cubic units.
What is the volume of a prism?The volume of a prism is the product of the base area and its height.
So, the volume of the given prism = area of trapezoidal base * height
Area of the trapezoidal base = 0.5 * (sum of parallel sides) * distance between parallel sides.
Area of the trapezoidal base =0.5 * (8+5) * 4
Area of the trapezoidal base =26 square unit
So, the volume of the given prism = 26*12 = 312 cubic units.
Hence, the volume of the trapezoidal prism comes to be 312 cubic units.

The function f left parenthesis x right parenthesis equals 3.5 square root of x plus 38 models the percentage of U.S. women in the labor force, f left parenthesis x right parenthesis , x years after 1960. Use this formula to solve the following questions.
US women in Labor ForceAccording to the model above, approximately what percentage of women will be a part of the work force in 1996? Does the given bar graph verify this result? Explain why or why not. Use complete sentences and proper labels to answer.
Answer:
59% of women will be a part of the work force in 1996
According to the bars, the percentage was in the range of 57.5 - 60.2. This verify the previous result.

What is an
equation of the line that passes through the points (-3,8) and (4,1)?
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5
Samantha is solving the following system of equations using the method of substitution: 3x + 2y = 11 - x + y = 3 The following are Samantha's first two steps. y= x + 3 3x + 2(x+3) =11 HINT: Solve the bottom equation for x and then plug that value back into the first equation to solve for y. Arrange the steps below to match the order you used to do this.
Place each of the remaining steps in the appropriate order to finish solving the system of equations.
1 5x =5
2 (1,4)
3 y=4
4 x=1
5 3x + 2x + 6 = 11
6 5x + 6 = 11
7 y= 1 + 3
Which ordered pair is the solution to the system of linear equations displayed on the graph below?
HINT: The solution is the point where the two lines intersect. What is the x coordinate and y coordinate at that point of intersection?
A:[tex](0,-\frac{3}{2} )[/tex]
B:[tex](-\frac{3}{2},0)[/tex]
C:[tex](0,\frac{3}{2}[/tex]
Which of the following inequalities can be represented by the graph below?
HINT: Can you find the equation for the boundary line? What is its y-intercept? What is its slope? Note that the region above the line is shaded.
A:[tex]y\geq2x-2[/tex]
B:[tex]y\geq \frac{1}{2}x-2[/tex]
C:[tex]y\geq \frac{1}{2}x +2[/tex]
Answer:
According to the numbers provided, the sequence is:
5, 6, 1, 4, 7, 3, 2
Solution of the two lines intersecting in the graph is answer B
The inequality that represents the graph is that of answer A
Step-by-step explanation:
First problem:
This is the sequence to solve for "x" once the substitution was made;
[tex]3x +2\,(x+3)=11\\3x+2x+6=11\\5x+6=11\\5x=11-6\\5x=5\\x=1\\[/tex]
Now that we know x, we use its value (1) in the substitution equation in order to find "y" and complete the ordered pair:
[tex]y=x+3\\y=1+3\\y=4[/tex]
Then the solution pair (x, y) is: (1, 4)
Therefore, according to the numbers provided in the list of possible steps, the order is:
5, 6, 1, 4, 7, 3, 2
Second problem:
The solution to the system is where the two lines two lines intersect: "the point -1.5 on the x axis. Notice that -1.5 can be written in fraction form as -3/2, this is the x-coordinate of the intersection point. The y-coordinate is y-0 since the point is on the x-axis. Therefore the point is (-3/2, 0) which is given by answer B).
Third problem: The boundary line seems to go through the points: (-4, -10) and (0, -2), so we can calculate the slope via the equation:
[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-2-(-10)}{0-(-4)}\\slope=\frac{8}{4}\\slope=2[/tex]
since the line's y-intercept is (0, -2), then the equation of the boundary line in slope-intercept is:
[tex]y=2x-2[/tex]
Since the shaded region includes the boundary line and the zone above it (with y-values larger than or equal to those point in the line), we can say that the inequality that represents this graph is:
[tex]y\geq 2x-2[/tex]

The perimeter of a rectangle is 34 units its width is 6.5 Units
Write an equation to determine the length(l) of the rectangle.
Answer: Length=10.5
Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)
-2L -2L (There is a line going down at the equal sign.
34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)
-34 -34
-2L=-21 (Divide both sides by -2) (Cancel out the -2's)
/-2 /-2
L = 10.5

Problem:

Step-by-step explanation:
The full area of half of a circle is equal to 180 degrees. To find the missing value of both A's you must take the full degrees of 180 and subtract 144 from 180. Next you have to take the remaining number and divide it by two because both of the missing value's are equivalent.
