Answer:
Step-by-step explanation:
Hello!
The Interquartile range (IQR) is a measurement of dispersion, it is the "distance" between the third quartile and the first quartile.
IQR = Q₃ - Q₁
Data 4, 5, 7, 8, 8, 9, 10, 12 (ordered from least to greatest)
n= 8
The first quantile separates the bottom 25% from the top 75%
First, you calculate the position of the quartile:
Position Q₁= (n+1)/4= (8+1)/4= 2.25
4, 5, 7, 8, 8, 9, 10, 12
The 1st quartile is between the 2nd and 3rd observation, so the next step is to calculate the average between the two observations to get the value of the quartile:
Q₁= (5+7)/2= 6
The third quantile separates the bottom 75% from the top 25%
First, you calculate the position of the quartile:
Position Q₃= (n+1)*(3/4)= (8+1)*(3/4)= 6.75
4, 5, 7, 8, 8, 9, 10, 12
The 3rd quartile is between the 6th and 7th observation, so the next step is to calculate the average between the two observations to get the value of the quartile:
Q₃= (9+10)/2= 9.5
IQR = Q₃ - Q₁= 9.5-6= 3.5
The correct answer is A.

what is the range of the function shown in the graph?
a. -♾ < y < 5
b. -♾ < y < ♾
c. -♾ < y < -5
d. -5 < y < ♾
Answer:
-♾ < y < 5
Step-by-step explanation:
Range is set of all possible values for Y.
To know the range of value from graph one needs to see points on axis beyond which the curve does not move.
Alternatively, we can say range is the value of y which is limiting the movement of curve beyond those limits.
Here we can see that upper point on curve is constrained at midpoint of 4 and 6 which is point 5.
Thus, upper limit is 5
which can be written as
y<5
___________________________________
For lower limit , it
Since , the at lower end curve is extended till the end of graph and the end of graph represents infinity. Also, this infinity is on the negative side of y .
Then lower end is -♾ .
which can be written as
y> -♾
Also we can see that graph is continuous one as there is no break in the curve between 5 and -♾.
Thus range of curve is from minus infinity to 5
which can be expressed as
-♾ < y < 5

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. Which equation explains the relationship between segment AB and segment A double prime B double prime?
Complete question:
Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. Which equation explains the relationship between segment AB and segment A double prime B double prime?
A) segment a double prime b double prime = segment ab over 2
B) segment ab = segment a double prime b double prime over 2
C) segment ab over segment a double prime b double prime = one half
D) segment a double prime b double prime over segment ab = 2
Answer:
A) segment a double prime b double prime = segment ab over 2.
It can be rewritten as:
[tex] A"B" = \frac{AB}{2} [/tex]
Step-by-step explanation:
Here, we are given triangle A″B″C which was formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin.
We know segment A"B" equals segment AB multiplied by the scale factor.
A"B" = AB * s.f.
Since we are given a scale factor of ½
Therefore,
[tex] A"B" = AB * \frac{1}{2} [/tex]
[tex] A"B" = \frac{AB}{2} [/tex]
The equation that explains the relationship between segment AB and segment A"B" is
[tex] A"B" = \frac{AB}{2} [/tex]
Option A is correct

Find the volume of a right circular cone that has a height of 14.3 ft and a base with a diameter of 17.2 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
Volume of the given cone is 1107.6 cubic feet.
Step-by-step explanation:
Formula to get the volume of a right circular cone is,
V = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r = radius of the circular base
h = height of the cone
Now we put the values in the given formula
Volume = [tex]\frac{1}{3}\pi (8.6)^2(14.3)[/tex] [ radius = [tex]\frac{17.2}{2}=8.6[/tex] ]
= [tex]\frac{1057.628\pi }{3}[/tex]
= 1107.55
≈ 1107.6 cubic feet
Therefore, volume of the given cone is 1107.6 cubic feet.

Two sides of a right triangle have the lengths 4 and 5. What is the product of the possible lengths of the third side? Express the product as a decimal rounded to the nearest tenth.
Answer:
19.2
Step-by-step explanation:
1st Case:
4 and 5 are legs of the right triangle.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+5^2=x^2
16+25=x^2
41=x^2
x=√41
√41 is about 6.4
x=6.4
2nd Case
5 is the hypotenuse of the right triangle and 4 is the legs.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+x^2=5^2
16+x^2=25
x^2=9
x=3
Final Step
We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2

To the nearest cent, how much interest will she earn in 2 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
10.50 is the interest
Step-by-step explanation:
B = p(1 + r)^t
P = 50
r = .10
t = 2
B = 50(1 + .1)^2
= 50(1.1)^2
= 50(1.21)
= 60.5
But we want to know the interest and this is the balance
60.5- 50 = 10.5

Elaine and Sandy both like lemonade Elaine has a 16 tablesspoon box of lemonade Sandy has an 18 tablespoon box of lemonade mix he likes his lemoade stronger and uses 3 tablespoons of mix for each glass of lemonade who will run out of mix first Elaine or Sandy
Answer: Sandy.
Step-by-step explanation:
Elaine has 16 tablespoons of lemonade, and uses 2 per glass.
then she can make 16/2 = 8 glasses of lemonade.
Sandy has 18 tablespoons of lemonade, and she uses 3 per glass,
then she can make 18/3 = 6 glasses of lemonade.
Then Sandy can make less glasses of lemonade than Elaine, this means that Sandy runs out of mixt first.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8.50. The auditorium can hold at most 79 people. The drama club must make no less than $460 from ticket sales to cover the show's costs. If 53 student tickets were sold, determine the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses.
Answer:
79 people can only be in this so we have 53 kids so 53 * 4 = 212
Step-by-step explanation:
However, there is 53 kids to find how many adults you will have to do 79 - 53 which that = 26 so 26 adults were there. so 26 * 8.50 = 221.
To fine how much money they earn you will just have to add them up so
$212 + $ 221 = $433 so they didn't really earn the amount of money they really want which is $ 460.
Thus the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses is 29 tickets.
Given,
The drama club is selling tickets to their play to raise money for the show's
expenses.
Each student ticket sells for $4 and each adult ticket sells for $8.50.
The auditorium can hold at most 79 people.
The drama club must make no less than $460 from ticket sales to cover
the show's costs.
If 53 student tickets were sold, determine the minimum number of adult
tickets that the drama club must sell in order to meet the show's expenses.
How to find the number of items from a total cost where each item cost is the same?We will divide the total cost by the cost of each item.
Example:
Cost of each item = $3
Total cost = $9
Number of items = $9 / $3 = 2
We have,
Student ticket:
Cost of each ticket = $4
Number of tickets sold = 53
Total sell from student tickets sold = 53 x $4 = $212
Adult ticket:
Cost of each ticket = $8.50
Number of adult tickets sold = M
Total sell of adult tickets sold = M x $8.50
Total number of people the auditorium can hold = 79
Minimum amount to make from ticket sales = $460
The remaining amount that needs to sale from adult tickets:
= $460 - $212
= $248
The number of adult tickets sold:
M = $248 / $8.50 = 29
Thus the minimum number of adult tickets that the drama club must sell in order to meet the show's expenses is 29 tickets.

The Math Club had a car wash to raise money for a competition. The members charged $10 for each car they washed. What is the independent variable in this relationship?
Answer:
The dependent variable for this case is the amount of money charged and the independent variable would be the number of cars washed.
And the reason why is because the dependnet variable is the variable of interest (money earned) and the independent the variable that controls the amount of money earned
