By analyzing the data and the interquartile ranges on the graphs, we will conclude that the correct option is A.
Which graph represents the data?The data is:
{10, 8, 50, 15, 10, 25, 20, 5, 12, 15, 20, 15, 25, 18, 20}
You can see that the minimum is 5, and the maximum is 50.
Now, if we analyze our data by ordering it from lowest to largest, we get:
{5, 8, 10, 10, 12, 15, 15, 15, 18, 20, 20, 20, 20, 25, 25, 50}
There are 16 numbers, so each interquartile has 4 elements. If you see the last interquartile (last 4 digits) you can see that it starts with a 20.
The graph where the last interquartile starts at 20, is the first graph, so the correct option is A.

I really need help please, any Expert willing to help me out? I don’t understand on #2, for a,b, and c.
Answers
Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.

In preparation for the upcoming school year, a teacher looks at raw test scores on the statewide standardized test for the students in her class. Instead of looking at the scores relative to the norms in the state, the teacher wants to understand the scores relative to the students who will be in the class. To do so, she decides to convert the test scores into z-scores relative to the mean and standard deviation of the students in the class. The mean test score in her upcoming class is 202, and the standard deviation is 38.2.
The following are the scores for some (not all) of her students. Complete the table using the dropdown menus.
Student Test Score z-score
A 126 1.25
B 98
C 97 -0.26
D 88
E 66 -1.88
F 95
G 111 0.47

For z = 2.00, test score = ______.
For z - -2.00, test score = ______.

E 66 -1.88
F 95 -2.801
G 111 0.47
H 105 -2.539
B)For z = 2.00, test score =278.4
For z - -2.00, test score =125.6
Step-by-step explanation:
Student Test Score z-score
A 126 1.25

F 95
G 111 0.47
H 105
Mean = [tex]\mu = 202[/tex]
Standard deviation = [tex]\sigma = 38.2[/tex]
For Student B
x= 98
[tex]Z=\frac{x-\mu}{\sigma}=\frac{98-202}{38.2}=-2.722[/tex]
For Student D
x= 88
[tex]Z=\frac{x-\mu}{\sigma}=\frac{88-202}{38.2}=-2.984[/tex]
For Student F
x= 95
[tex]Z=\frac{x-\mu}{\sigma}=\frac{95-202}{38.2}=-2.8010[/tex]
For Student H
x= 105
[tex]Z=\frac{x-\mu}{\sigma}=\frac{105-202}{38.2}=-2.539[/tex]
Now we are supposed to find test scores :
For z = 2.00
[tex]Z=\frac{x-\mu}{\sigma}\\2=\frac{x-202}{38.2}\\(2 \times 38.2)+202=x\\278.4=x[/tex]
For z = -2.00
[tex]Z=\frac{x-\mu}{\sigma}\\-2=\frac{x-202}{38.2}\\(-2 \times 38.2)+202=x\\125.6=x[/tex]
Hence ,For z = 2.00, test score =278.4
For z - -2.00, test score =125.6

9+8 divided by (-4)-12
Answers
Answer:
-1 1/16 if mixed number. If you want decimal form: -1.0625
Step-by-step explanation:
Your question was this:
9+8/(-4)-12
I want you first to get rid of the -4-12 and be done with it so here are the steps:
Rule: If negative subtract a negative, that shall be an addition problem with the larger number's symbol.
In this case, we need to add 4 and 12 together and include the negative symbol in front of the answer.
That shall be -16
Our Question now:
9+8/-16
So do 9+8 which is 17.
Our question now:
17/-16
Your answer is an improper fraction so you could change it to a mixed number or you could simply divide 17 and -16 to get a negative decimal.
Here are the possible answers:
Mixed Number: -1 1/16
Decimal Form: -1.0625
divide 8 and -4 to get -2

Which of the following is the best first step to convert the following equation to slope
intercept form?
2-4y =-12
Answers
Answer: y=7/2 in decimal form 3.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2-4*y-(-12)=0
Pull out like factors :
14 - 4y = -2 • (2y - 7)
Solve : 2y-7 = 0
Add 7 to both sides of the equation :
2y = 7
Divide both sides of the equation by 2:
y = 7/2 = 3.500
Jasmine is riding on a carousal. She is sitting 9.5 feet from the center and it takes 20 seconds to
complete a rotation. What is Jasmine's linear speed (rounded to the nearest tenth)?
Answers
Answer:
2.983 ft/sec
Step-by-step explanation:
Given that
Distance between center and Jasmine riding on a carousal = 9.5 feet
Time taken to complete one rotation = 20 seconds
To find:
Jasmine's linear speed = ?
Solution:
Number of revolutions per minute = [tex]\frac{60}{20} = 3[/tex]
Formula for linear speed is given as:
[tex]v=\dfrac{2\pi}{60}\cdot r\cdot RPM[/tex]
Where [tex]r[/tex] is the radius of circular path and
[tex]RPM[/tex] is the number of revolutions per minute.
[tex]v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}[/tex]
Therefore, the linear speed is 2.983 ft/sec.

Answers
Answer:
Closet #1.
Step-by-step explanation:
Closet #1 is 4x5x8, right? so, 4x5=20, and 20x8=160 feet. Closet #2 is 6x3x8, and 6x3 is 18. That's already less than 20 even before we multiply by 8. So, the answer to your question is Closet #1.
Answer:
Answer: The first closet is larger.
Step-by-step explanation:
Closet #1
V = l × w × h
V = 4 ft. × 5 ft. × 8 ft.
V = 160 cu. ft.
Closet #2
V = l × w × h
V = 6 ft. × 3 ft. × 8 ft.
V = 144 cu. ft.
Compare the size of the closets
160 cu. ft. > 144 cu. ft.
Answer: The first closet is larger.
