What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15
Answers
28, 40, 43, 43, 45, 50, 50
Total number of values = 7
Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:
1st Half = 28, 40, 43
2nd Half = 45, 50, 50
Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.
IQR or the Inter Quartile Range is the difference of Q3 and Q1.
So, IQR= Q3 – Q1 = 50 – 40 = 10
Thus, IQR for the given data is 10
The interquartile range(IQR) of the data set is:
10
Step-by-step explanation:The data points according to the stem and leaf plot are as follows:
28 40 43 43 45 50 50
We know that the median of the data is the central tendency of the data and always lie in the middle of the data.
Here looking at the data we have:
Median= 43
Similarly the lower set of data is:
28 40 43
Hence, the first quartile or the lower quartile i.e. [tex]Q_1[/tex] is the median of the lower set of data.
Hence,
[tex]Q_1=40[/tex]
Similarly, the upper set of data is:
45 50 50
Hence, the upper quartile or the third quartile i.e. [tex]Q_3[/tex] is the median of the upper set of data.
Hence,
[tex]Q_3=50[/tex]
The interquartile range(IQR) is calculated as:
[tex]IQR=Q_3-Q_1\\\\IQR=50-40\\\\IQR=10[/tex]

If you take a certain number 2.5 times then add 1.75 and divide the result by 0.8, you’ll get 37.5. What was the original number?
Answers
Answer:
The original number is 11.3
Step-by-step explanation:
Let the number is x and then we form the equation to solve it for the value of x.
1- Number is multiplied by 2.5 then it becomes = 2.5x
2- Then we add 1.75 to the expression then new expression will be = 2.5x + 1.75
3- We divide the result by 0.8 then expression will be = [tex]\frac{2.5x + 1.75}{0.8}[/tex]
4- Now the final expression is equal to 37.5 so the equation will be
[tex]\frac{2.5x + 1.75}{0.8}[/tex] = 37.5
Now we multiply 0.8 in both the sides of the equation
[tex]\frac{2.5x + 1.75}{0.8}[/tex]×0.8 = 37.5×0.8
2.5x + 1.75 = 30
2.5x = 30 - 1.75
2.5x = 28.25
x = 28.25/2.5 = 11.3

The first pentagon is dilated to form the second pentagon. Drag and drop the answer to correctly complete the statement. The scale factor is . A pentagon with a side length of 4. An arrow points to a larger pentagon with a side length of 5
Answers
4x/4 = 5/4
x = 1.25
The scale factor is 1.25.
Final answer:
To find the scale factor for the dilation of a pentagon from a side length of 4 to a side length of 5, divide the new dimension by the original dimension, resulting in a scale factor of 1.25.
Explanation:
The question asks about finding the scale factor used to dilate a pentagon from a side length of 4 to a side length of 5. To find the scale factor, we compare the new dimension to the original dimension. In this case, the side length of the second pentagon is 5, and the side length of the first pentagon is 4. To find the scale factor, we divide the new dimension by the original dimension, which is 5/4. Hence, the scale factor is 1.25.
To clarify, the scale factor is determined by dividing the new dimension (5) by the original dimension (4), yielding 5/4. Therefore, the scale factor is indeed 1.25. This indicates that each side of the pentagon has been multiplied by 1.25 to achieve the dilation from a side length of 4 to a side length of 5.
Maggie and her friend visit a beach that has a shoreline 2 2/5 kilometers long. They walk along 2/3 of it. How many kilometers of the beach shoreline do they walk?
Answers
If we want to find 2/3 of 2 2/5, we can multiply the fractions together.
[tex] \frac{2}{3} * 2 \frac{2}{5} [/tex]
= [tex] \frac{24}{15} [/tex]
= [tex] \frac{8}{5} [/tex]
= [tex]1 \frac{3}{5} [/tex]
This means that Maggie and her friend have walked [tex] 1 \frac{3}{5} [/tex] kilometers of the beach shoreline.
To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along. Maggie and her friend walk 8/5 kilometers of the beach shoreline.
Explanation:To find out how many kilometers of the beach shoreline Maggie and her friend walk, we need to multiply the length of the shoreline by the fraction they walk along.
First, we need to convert the mixed number 2 2/5 to an improper fraction. We can do this by multiplying the whole number (2) by the denominator (5) and adding the result to the numerator (2), then putting the new numerator over the denominator. So, 2 2/5 is equal to (2 * 5 + 2) / 5 = 12/5.
Next, we can multiply the length of the shoreline (2 2/5) by the fraction they walk along (2/3). Multiply the whole number and numerator separately, then add the products and put the result over the denominator.
So, (12/5) * (2/3) = (12 * 2) / (5 * 3) = 24/15 = 8/5.
Maggie and her friend walk 8/5 kilometers of the beach shoreline.

Final answer:
Louise has walked 9 miles after completing 3/4 of her 12-mile fundraising walk. Thus, option b is correct.
Explanation:
The student's question asks how many miles Louise has walked if she has completed 3/4 of her 12-mile fundraising walk. To find the distance walked, multiply the total distance by the fraction completed. So, Louise has walked 3/4 of 12 miles, which is calculated as follows:
Multiply 3/4 by 12.
3/4 * 12 = 9.
Thus, Louise has walked 9 miles.

Formulate a system of equations to represent this situation, with f = the amount of money that Frank spent and r = the amount of money that Rachel spent. Frank and Rachel spent a total of $15.75. If Rachel spends twice as much money as Frank, how much money did they each spend?
A)
B)
C)
D)
Answers
Rachel and Frank spends $10.5 and $5.25 respectively.
It is given to us that
f is the amount of money that Frank spent and
r is the amount of money that Rachel spent.
Frank and Rachel together spent a total of $15.75.
Rachel spends twice as compare to Frank
The equation that represents this situation:
1. f + r = $15.75
2. r = 2f
Substituting r = 2f in equation 1.
f + r = 15.75
f + 2f = 15.75
3f = 15.75
f = 5.25
Substituting f = 5.25 in equation 2.
r = 2f
r = 2(5.25)
r = 10.5
Thus, Rachel spends $10.5 and Frank spends $5.25.
