The box plot displays the number of push-ups completed by 9 students in a PE class.
A box plot uses a number line from 9 to 56 with tick marks every 2 units. The box extends from 20 to 42.5 on the number line. A line in the box is at 35. The lines outside the box end at 10 and 55. The graph is titled Push-Ups In PE and the line is labeled Number of Push-Ups.
Which of the following represents the value of the lower quartile of the data?
10
20
42.5
55
The lower quartile of the data set that is represented by the box plot described above is: B. 20.
How to Find the Lower Quartile from a Box Plot?The lower quartile, also known as the first quartile (Q1), is the value below which 25% of the data lies. In a box plot, it is represented by the bottom of the box.
According to the given information for the box plot, the box extends from 20 to 42.5 on the number line. Therefore, the lower end of the box represents the value of the first quartile (Q1).
Hence, the value of the lower quartile is 20. Therefore, the correct answer is: B. 20.

Step-by-step explanation:
because 1 1/2 x 2/3 = 2 1/4
Answer:
1 1/2 = 3/2
2 1/4 = 9/4
3/2 divided by 9/4 = 3/2 multiplied by 4/9 = 2/3
EXPLANATION : when we have 2 fractions and we have to divide them , we have to reverse the fraction that we are dividing by and multiply it. sometimes we can simplify the fractions , sometimes we can't. for example , with 3/2 multiplied by 4/9 we simplified 3 and 9 and the 2 and the 4 which left us with 1/1 ( 1 ) multiplied by 2/3 , which gave us the answer 2/3 .

Answer: dd 1 and 9
Step-by-step explanation:

When comparing the data, a measure of variability which should be used for both sets of data to determine the location with the most consistent temperature is: C. Range, because Sunny Town is skewed.
What is skewness?In Mathematics, skewness can be defined as a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.
By critically observing the box plot (box-and-whisker plot) which represent Sunny Town, we can logically deduce that it is skewed.
On the other hand (conversely), the box plot (box-and-whisker plot) for Desert Landing is symmetrical (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

The table below shows the change in price of a particular share on the stock market.
Daily share price changes
Day Daily change (In dollars)
1 +2.75
2 -4.375
3 +0.875
4 -2.5
Part A: By how did the price of the share change from the start of day 1 to the end of day 4?
Part B: At the end of day 4 the price of the share is $102.85. What was the price of the share at the start of day 1?
Answer:
Part-a: The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part-b: The price of the share at the start of day 1 was $106.10.
Step-by-step explanation:
Part A: To calculate the change in price from the start of day 1 to the end of day 4, we need to add up all the daily changes. The daily changes given are:
Day 1: +2.75
Day 2: -4.375
Day 3: +0.875
Day 4: -2.5
Adding these values together:
Change = 2.75 - 4.375 + 0.875 - 2.5 = -3.25
The price of the share decreased by $3.25 from the start of day 1 to the end of day 4.
Part B: To find the price of the share at the start of day 1, we need to subtract the total change from the given price at the end of day 4.
Price at the end of day 4 = $102.85
Total change = -3.25
Price at the start of day 1 = Price at the end of day 4 - Total change
= $102.85 - (-3.25)
= $102.85 + 3.25
= $106.10
Therefore, the price of the share at the start of day 1 was $106.10.

Answer my other questions and get brainliest!
Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).
Find the median and mean of the data set below:

Answer:
Mean: 24
Median: 26
Step-by-step explanation:
0, 8, 25, 26, 31, 33, 45
26 is in the middle so median = 26
Mean = (0 + 8 + 25 + 26 + 31 + 33 + 45) / 7 = 24

A crafts worker is knitting a circular rug that has a diameter of 86 inches. He would like to put trim around the outer edge of the rug. If 1 inch = 2.54 centimeters, how many centimeters of trim would he need? Use π = 3.14 and round to the nearest centimeter.
686 centimeters
343 centimeters
135 centimeters
106 centimeters
Answer:
686 centimeters
Step-by-step explanation:
d= 86 inches
d=2r
86 =2r
r=43
C = 2πr
C = 2(3.14)(43) =270.04 inches
1 inch = 2.54 centimeters
270.04 (2.54) = 685.9016 centimeters ≈686 centimeters
Which ordered pair is a solution to the system of linear equations?
x + 4y = 6
y = −4x − 6
A: (−2, −2)
B: (−2, 2)
C: (2, 2)
D: (2, −2)
Answer: B (-2, 2)
Step-by-step explanation:
You substitute the values of the variables into each equation to see if they are both true.
(-2) + 4(2) = 6
(-2) + 8 = 6
6 = 6
2 = -4(-2) - 6
2 = 8 - 6
2 = 2
When pulling in B to both equations, both are true!
So B is your answer.
Answer:
B: (-2, 2)
Step-by-step explanation:
We can solve this equation using substitution:
x+4y=6
4y=6-x
y=[tex]\frac{-x}{4}[/tex]+[tex]\frac{3}{2}[/tex]
y=-4x-6
So, since y equals both of these expressions, the expressions must be equal.
[tex]\frac{-x}{4}[/tex]+[tex]\frac{3}{2}[/tex] = -4x-6
[tex]\frac{15x}{4}[/tex]=[tex]\frac{-15}{2}[/tex]
x=[tex]\frac{-15}{2}[/tex]*[tex]\frac{4}{15}[/tex]=-2
y= -4x-6 = -4(-2) - 6 = 8-6 = 2
x=-2
y=2
The ordered pair is (-2, 2), which is choice B.
Hope this helps! :)
Since this is multiple choice, you can also plug in each ordered pair into the equations with the x and y values, but when it is open response, substitution is a good option.
A new physical therapy is being tested in an experimental setting to see if the new methods reduce the recovery time for patients who recently underwent surgery for a torn ACL, a ligament in your knee. To do this, the researchers in the study first performed intake on participants by observing their Body Mass Index (BMI) and had them take a survey to describe their diet and their exercise habits.
Then, the participants were split into three groups: the first group received no physical therapy, the second group received traditional physical therapy, and the third group received the new experimental physical therapy.
The group which receives no physical therapy would best be described as which of the following?
Explanatory Variable
Response Group
Control Group
Experimental Unit
Answer: The group which receives no physical therapy would best be described as the Control Group.
In an experimental study, the control group is a group of participants who do not receive the treatment being tested. They are used as a basis for comparison to evaluate the effectiveness of the treatment. In this case, the researchers are testing whether the new physical therapy reduces the recovery time for patients who underwent surgery for a torn ACL. The control group allows the researchers to compare the recovery time of patients who received no physical therapy to those who received either traditional or experimental physical therapy.
