The box plot shows the number of jumping jacks completed in a workout class by the class members. A box plot uses a number line from 14 to 54, with tick marks every one unit. The box extends from 26 to 49 on the number line. A line in the box is at 40. The lines outside the box end at 15 and 52. The graph is Jumping Jacks Completed, and the line is labeled Number of Jumping Jacks. Which of the following lists the range and IQR for this data? The range is 23, and the IQR is 37. The range is 40, and the IQR is 37. The range is 40, and the IQR is 23. The range is 37, and the IQR is 23.
Answers
- Range: The range is the difference between the maximum and minimum values in a data set.
- IQR: The IQR is the range of the middle 50% of the data values. It is calculated by finding the difference between the third quartile (Q3) and the first quartile (Q1).
In the given box plot:
- The lines outside the box represent the minimum and maximum values.
- The box represents the middle 50% of the data, with the line inside the box representing the median (or second quartile, Q2).
- The distance between the lower whisker and the bottom edge of the box represents the first quartile (Q1), and the distance between the upper whisker and the top edge of the box represents the third quartile (Q3).
Based on the information provided in the box plot, we can determine the range and IQR as follows:
- The minimum value is represented by the lower whisker, which ends at 15.
- The maximum value is represented by the upper whisker, which ends at 52.
- Q1 is located at the bottom edge of the box, which is 26.
- Q3 is located at the top edge of the box, which is 49.
Now we can calculate the range and IQR:
- Range: maximum value - minimum value = 52 - 15 = 37
- IQR: Q3 - Q1 = 49 - 26 = 23
Therefore, the correct statement is:
The range is 37, and the IQR is 23.
Answer:
The range is 37, and the IQR is 23.
Step-by-step explanation:
A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.
Five-number summaryMinimum value is at the end of the left whisker.Lower quartile (Q₁) is the left side of the box.Median (Q₂) is the vertical line inside the box.Upper quartile (Q₃) is the right side of the boxMaximum value is at the end of the right whisker.From the given information, the five-number summary of the Jumping Jacks box plot is:
Minimum = 15Lower quartile (Q₁) = 26Median (Q₂) = 40Upper quartile (Q₃) = 49Maximum = 52RangeThe range is the difference between the maximum and minimum values. Therefore, the range for the data is:
\(\sf Range = 52 - 15 = \boxed{\sf 37}\)
Interquartile range (IQR)The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:
\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)
SummaryThe range is 37, and the IQR is 23.

Segment AB has point A located at (5, 4). If the distance from A to B is 7 units, which of the following could be used to calculate the coordinates for point B? (5 points)
a- 7 = square root of the quantity of x plus 4 all squared plus y plus 5 all squared
b- 7 = square root of the quantity of x plus 5 all squared plus y plus 4 all squared
c- 7 = square root of the quantity of x minus 4 all squared plus y minus 5 all squared
d- 7 = square root of the quantity of x minus 5 all squared plus y minus 4 all squared
Answers
Answer: (-2, 4)
Step-by-step explanation: The right coordinate for point B with 7 units as distance is (-2,4). To arrive at the answer, the distance formula is used. The solution for the problem is:
7= √[(-2-5)² + (4-4)²)
Finding the coordinates for point B will be done through the square root of the quantity of x minus 5 all squared plus y minus 4 all squared so option (D) will be correct.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given a point A(5,4) and another point B (x,y).
Distance between A to B = 7 units.
To find the distance between any two the following formula is used.
\(\sqrt{(x_{2} - x_{1} )^{2} + {(y_{2} - y_{1} )^{2}\) hence, it is clear that option (D) will be correct.

Senora Cruz asks her student Molly to determine the formula for finding the area of the parallelogram and the rectangle. Molly says the formulas are the same. Is she correct?why or why not?
Answers
She is correct in a way that a parallelogram can be made into rectangle.
What is Parallelogram?Parallelogram is a type of polygon with four sides, four angles and four vertices. It is a type of Quadrilateral.
Opposite sides are parallel, and the opposite sides and opposite angles are equal.
Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.
The difference between a rectangle and a parallelogram is that all the angles are not right angles in parallelogram.
Area of a rectangle = Length × Width
That is the product of two opposite side lengths.
If a parallelogram is taken, then, it can be made into a rectangle by joining perpendicular from the endpoint of longer side to the opposite side and taking the resulting triangle to other side.
Then it becomes a rectangle where length is the base length of parallelogram and width is the height of the parallelogram.
Hence Molly is correct in a way that a parallelogram can be made into rectangle.

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units

Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

A cylindrical container has a height
of 14 inches and radius of 3.2 inches.
It is filled with pasta, but there is
1.5 inches of space left at the top.
How many cubic inches of pasta are
in the container?
Answers
Answer:
80 cubic inchesStep-by-step explanation:
Please look at the picture below also as you read the answer!
1.
To find the cubic inches of pasta, first, let's find the diameter.
If the radius (always half of the diameter) is 3.2, then what's the diameter?
3.2+3.2=6.4
So, the diameter is 6.4 inches
2.
Find how much height is the pasta at
The container is 14 inches high, but the past is only filled till the top leaving 1.5 inches of space, what can we do to find out how much height is the pasta filled till?
14-1.5=12.5
So, the height till what the pasta is filled till is 12.5
3.
The formula for finding this...
V=BxH
V=Volume
B=Base
H=Height
4.
Applying the formula
BxH=?
Base = 6.4 inches
Height = 12.5 inches
6.4x12.5=?
64x125=8000
=80.00
(after removing 2 zeros in the back, because the original number was having decimal)
So, hence, the volume of our awesome cylinder of pasta is 80 Cubic Inches!
The pasta in the container is 80 Cubic Inches in volume.Learn more:
