Answer:
42
Step-by-step explanation:
im pretty sure I got this right I did it in my head
Answer:
m 5 = 42
Step-by-step explanation:
A line is 180 degrees. m 4 = 138 degrees. 180 - 138 = 42 degrees. this makes m 1 = 42 degrees and m 5 is equal to m 1.
What is the slope of the line? y+3= -4(x+7)
Answer:
Slope = -8.000/2.000 = -4.000
x-intercept = -31/4 = -7.75000
y-intercept = -31/1 = -31.00000
Step-by-step explanation:
1: Graph of a Straight Line
2: Calculate the Y-Intercept
3: Calculate the X-Intercept
4: Calculate the Slope
5: Geometric figure: Straight Line
Answer: Slope = -8.000/2.000 = -4.000

Which best describes the type of association shown in this scatter plot?
•no association
•non-linear association
•positive linear association
•negative linear association
Answer:
Negative linear association/correlation.
Step-by-step explanation:
The type of association that is shown in the scatter plot is negative linear association since it declining at a steady rate with a few outliers. It resembles a line going downwards or sloping downwards.
The best describes the type of association shown in this scatter plot is,
⇒ negative linear association
We have to given that,
A scatter plot is shown in figure.
Since, this scatter plot declining at a steady rate with a few outliers.

The equation of this graph would be (x − 5)^2 = -8(y + 4). So option D is correct.
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.

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

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.

The given bar graph shows the percentage of U.S. women in the labor force from 1960 through 2010. 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.
Step-by-step explanation:
In the figure attached, the bar graph is shown.
f(x) = 3.5√x + 38
where f(x) models the percentage of U.S. women in the labor force x years after 1960. In 1996, x = 1996 - 1960 = 36. Replacing it into the equation:
f(36) = 3.5√36 + 38 = 59%
If f(1)=1 and f(n)=5f(n−1)+5 then find the value of (4).

Step-by-step explanation:
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.

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 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
