Two data sets contain an equal number of values. The double box and whisker plot represents the values in the data set. Compare the data sets using measures of center and variation.
Answers
Answer with explanation:
From the box and whisker plot of seventh grade we have:
The minimum value =6
First quartile or lower quartile i.e. = 14
Median or second quartile i.e. = 18
Third quartile or upper quartile i.e. =22
and maximum value = 26
From the box and whisker plot of eighth grade we have:
The minimum value =22
First quartile or lower quartile i.e. = 26
Median or second quartile i.e. = 30
Third quartile or upper quartile i.e. = 34
and maximum value = 38
a)
The overlap of the two sets of data is as follows.
The upper quartile or third quartile of seventh grade is same as the minimum value of the data of eighth grade.
And the maximum value of seventh grade is same as the lower quartile of eighth grade.
b)
IQR is calculated as the difference of the Upper quartile and the lower quartile
i.e.
so, IQR of seventh grade is:
22-14=8
IQR of seventh grade=8
IQR of eighth grade is:
34-26=8
Hence, IQR of eighth grade=8
c)
The difference of the median of the two data sets is:
30-18=12
Hence, the difference of median is: 12
d)
As the IQR of both the sets is same i.e. 8.
Hence, the number that must be multiplied by IQR so that it is equal to the difference between the medians of the two sets is:
Hence, the number is : 1.5

The difference between three times a number and the sum of twelve squared plus ninety-two equals five hundred fourteen.
Answers
Answer:
Number = 250
Step-by-step explanation:
Let x = "a number"
Difference means subtraction:
3x - (12^2 + 92) = 514
3x = "three times a number"
12^2 + 92 = "the sum of twelve squared and ninety two"
Solve from there.

A triangle has two sides that are 4 in. And 10 in. What could be the length of the third side of the triangle? Select all that apply.
Answers
Answer:
see explanation
Step-by-step explanation:
Given 2 sides of a triangle then the range of the third side x is
difference of 2 sides < x < sun of 2 sides , that is
10 - 4 < x < 10 + 4
6 < x < 14
Thus the third side can be 7, 8, 9, 10, 11, 12, 13

x = 3.33
y = -2
Step-by-step explanation:
x(4) + 7 = 20
4x +7-7 = 20-7

x = 3.33
(y+7)(4) = 20
y+7 = 20/4
y+7 = 5

At 7:00 am, the temperature was -4℉. At 9:00 am, it was 8° warmer. What was the temperature at 9:00 am? *
Answers
4℉.
What we know about Degrees is that there is a Positive type and a negative type.
(i.e: 30℉ is positive and -30℉ is negative.)
If the temperature was -4℉ at 7AM, then it is negative. If it goes up by an amount that is more than 4 then that negative will go up to a positive temperature. In this case: At 9AM it was 8° warmer.
Warmer is a keyword. If it is warmer by an amount, Negative temperatures will go up to a positive and positive temperature will just go up. If it gets cooler, negative temperatures will go down further and positive temperatures will go down to a negative.
So lets work out this problem with our newfound knowledge.
-4° F at 7AM
8° warmer at 9AM
-4 + 8 = 4.
The temperature was 4° at 9AM.

A local bakery sells cupcakes for $3.50 each. The fixed monthly cost totals $275 which includes rent, utilities, and wages. Each cupcake costs the bakery 0.90 to make.
Answers
Answer: 110 cupcakes
Step-by-step explanation:
Assuming this question is asking for the breakeven point, you can find that by using the formula:
= Fixed cost / Contribution margin
Contribution margin = Sales price - variable cost (amount to make one cupcake)
= 3.50 - 0.90
= $2.60
Breakeven point = 275 / 2.60
= 109.77
= 110 cupcakes
