... between 32 and 37.
Answer:
The correct option is 3.
Step-by-step explanation:
From the given box plot it is clear that
1. The left end point of the line is 27. So, the minimum value of the data is 27.
2. The left end of the box is 32. It means the first quartile of the data is 32.
3. The line inside the box represents the median. So the median of the data is 36.
4. The right end of the box is 37. It means the third quartile of the data is 37.
5. The right end point of the line is 40. So, the maximum value of the data is 40.
It means the box part of the box plot contains all the values between 32 and 37.
Therefore the correct option is 3.
I thought of a number, added 4 5/7 to it, and got the number equal to the original one times 12. What was the original number?
Answer:
[tex]\frac{3}{7}[/tex]
Step-by-step explanation:
The number you thought of and original number = x
The number you thought of and added [tex]4\frac{5}{7}[/tex] and got the number equal to the original on times 12
[tex]x +4\frac{5}{7} = 12x[/tex]
Convert [tex]4\frac{5}{7}[/tex] to an improper fraction so it will be easier to work with.
[tex]x +\frac{33}{7} = 12x[/tex]
[tex]\frac{33}{7} = 12x - x[/tex]
[tex]\frac{33}{7} = 11x [/tex]
[tex]\frac{\frac{33}{7}}{11} = \frac{11x}{11} [/tex]
[tex]\frac{33}{7} * \frac{1}{11} = x [/tex]
[tex]\frac{3}{7} = x [/tex]
[tex]x = \frac{3}{7}[/tex]
The original number that the student thought of in the problem can be found by solving the algebraic equation x + 4 5/7 = 12x. After converting the mixed fraction to an improper fraction and simplifying, the original number is 33/77.
Explanation:The original question is a kind of algebra problem. Let's denote the original number as x, according to the student's description, it follows this formula: x + 4 5/7 = 12x. To solve this equation, you need to collect terms involving x on one side. This gives you 11x = 4 5/7.
Next, convert 4 5/7 to an improper fraction. That gives you 33/7. So, your equation now is 11x = 33/7. Finally, solve for x by dividing both sides of the equation by 11, x = 33/77. This is your original number.

What is the slope of the line that passes through the points (−4,0) and (2, 0)? Write your answer in simplest form.
since both points have a y- coordinate of zero, this is a horizontal line parallel to the x- axis
hence slope = 0
We want to find the slope of a line given that we know two points on the line.
We will see that the slope of the line is 0.
Generally, if we know that a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of that line is given by:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we know that the line passes through (-4, 0) and (2, 0) then the slope will be:
[tex]a = \frac{0 - 0}{2 - (-4)} = 0[/tex]
The slope is equal to zero, meaning that this is a horizontal line (as you can see in the points, the y-component does not change).

Nayan Patel purchases a compact vehicle with an MSRP of $17,980.00, including the destination charge and title fee. He selects a 4-way power front passenger seat, which costs 8 times the amount of remote keyless entry. The total cost of the compact vehicle, including a 7.2% sales tax, is $20,000.00. Find the cost of the remote keyless entry.
A $676.71
B $150.38
C $601.53
D $75.19
Answer:
$75.19
Step-by-step explanation:
Let 'x' be the cost of remote keyless entry.
And [tex]8x[/tex] be the cost of 4-way power front passenger seat.
Total cost = destination charge + title fee + taxes
So we have the equation:
[tex]20,000 = (17,980+x+8x)+0.072(17,980+x+8x)[/tex]
Now solving for 'x', we get:
[tex]20,000 = (17,980+9x)+0.072(17,980+9x)[/tex]
[tex]20,000=17,980+9x+1294.56+0.648x[/tex]
[tex]20,000=19274.56+9.648x[/tex]
[tex]725.44=9.648x[/tex]
[tex]x=\frac{725.44}{9.648} =75.19[/tex]

Each student needs 35 craft sricks for an art project. The art teacher has 7,140 craft sticks. How many students can get craft stick from teacher?
What number can i use to estimate the quotient?
Explain how to check the answer to a division problem.
Solution.
Answer:
204 students
just do 7140/35= 204
Step-by-step explanation:
Number of students who can get craft sticks are 204 .
To determine how many students can get craft sticks from the teacher, we need to divide the total number of craft sticks by the number of craft sticks each student needs.
Step-by-Step Solution
The total number of craft sticks is 7,140.
Each student needs 35 craft sticks.
To find out how many students can get the craft sticks, divide the total number of craft sticks by the number of craft sticks each student needs:
7,140 ÷ 35 = 204
Therefore, 204 students can get craft sticks from the teacher.
Estimation and Checking
To estimate the quotient, you can round the numbers to make the division easier. For example, round 7,140 to 7,000 and 35 to 30:
7,000 ÷ 30 ≈ 233.33
This estimation tells us that our division answer is reasonable, falling close to this rounded solution.
To check the division, multiply the quotient by the divisor and see if you get the original dividend:
204 × 35 = 7,140
Since the result matches the original number of craft sticks, the answer is verified as correct.
Figure ABCD is a parallelogram with point C (3, −2). Figure ABCD is rotated 90° counterclockwise to form figure A′B′C′D′. What coordinate would be the output for point C'?
C' (2, −3)
C' (−2, 3)
C' (2, 3)
C'(2, 3 )
under a counterclockwise rotation about the origin
a point (x, y ) → (- y, x ) hence
C(3, - 2 ) → C'(2, 3 )
Answer:
C' (2, 3)
Step-by-step explanation:
Remember that when you are rotating something 90 degrees and counter clockwise you just need to interchange the X and Y values, and change the value of the new X to a negative position because it woul be located in the second quarter:
(x,y) rotated 90º counter clockwise= (-y,x)
(3,-2)=(-(y),x)=(-(-2),(3)=(2,3)
So the answer would be C' (2, 3)

Since it's Wednesday, Buy for Less gives a 5% discount for purchases. The items in Rhonda's cart total $53.75. She needs to know the cost of the items with the discount. So, she multiplies 5% times $53.75 and subtracts the amount from $53.75. Which expression would give Rhonda the same result in one step? A) .90(53.75) B) .95(53.75) C) 1.05(53.75) D) 53.75 - .05(53.75)
she needs to count how much 90% is so
85.00 times 90%
or 8500 times 0.9
Answer:
B) .95(53.75)
Step-by-step explanation:
5% is equal to 0.05. So the following expressions are equivalent.
5% × 53.75 = 0.05 × 53.75
To find the final price, she first takes the 5% and then subtracts the amount from 53.75. That is,
53.75 - 5% × 53.75 = 53.75 - 0.05 × 53.75
We can take out the common factor 53.75
53.75 . (1 - 0.05) = 53.75 . 0.95 = 0.95 . 53.75 = 0.95 (53.75)
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner Mila, swam 2/3 of Logan's distance in 1/4 of an hour. What is Logan's average swimming speed?
The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) Of course "per" means "divided by".
speed = distance/time
speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h
Logan's average speed is 2.25 kilometers per hour.

A ) x =1 and x =-6
B ) x = -1 and x=6
C ) x= -7
D ) x = 2 and x = 3
E ) x = -6 and x = -7
Answer:
B) x = -1 and x = 6
Step-by-step explanation:
The values that must be excluded from the domain are the values for which f(x) is undefined. Those values are the ones that make the denominator be zero.
We can find the zeros of the denominator by factoring.
... x² -5x -6 = (x +1)(x -6)
The product is zero when either factor is zero, so when x=-1 or x=6.

y = 4
Hey there!!
We have:
... (2y+1.6)/0.8 = 30/2.5
... (2y+1.6)/0.8 = 12
Multiplying 0.8 on both sides.
... (2y+1.6) = 12×0.8
... 2y+1.6 = 9.6
Subtracting 1.6 on both sides:
... 2y = 9.6-1.6
... 2y = 8
Dividing by 2 on both sides:
... y = 8/2
... y = 4
Hence, the required answer is 4.

Jerrica is selling calendars to raise money for a community group she belongs to. A basic calendar sells for $10 and a deluxe calendar sells for $15. The number of deluxe calendars Jerrica sells must be greater than or equal to 3 times the number of basic calendars she sells. She has at most 72 calendars to sell. The number of basic calendars sold is represented by x and the number of deluxe calendars sold is represented by y. What is the maximum revenue she can make?
A. $810
B. $990
C. $1080
D. $1296
The correct answer is option B.
Let the basic calendars be = x
Let the deluxe calendars be = y
Total calendars are = 72 , so equation becomes:
[tex]x+y=72[/tex] .............(1)
Cost of 1 basic calendar = $10
So, cost of all basic calendars will be = 10x
Cost if 1 deluxe calendar = $15
So, cost of all deluxe calendars = 15y
As given, the number of deluxe calendars must be greater than or equal to 3 times the number of basic calendars, the equation becomes
y=3x ...............(2)
Putting the value of y from (2) in (1)
[tex]x+y=72[/tex]
[tex]x+3x=72[/tex]
[tex]4x=72[/tex]
x=18
As, y=3x
y=[tex]3\times18=54[/tex]
So we have 18 basic calendars and 54 deluxe calendars.
Cost of 18 basic calendars will be= [tex]18\times10=180[/tex]
Cost of 54 deluxe calendars will be = [tex]54\times15=810[/tex]
So total amount is = $990
Hence, the maximum revenue is $990.

Find the average rate of change of f ( x ) = -2x^2 + 4x + 2 as X varies from 1.2 to 3.8
Here we need to find the average rate of change of [tex]f(x)[/tex].
Now,
[tex]f(x)=-2x^2+4x+2[/tex]
Let us find out the value of [tex]f(x)[/tex] at the point [tex]x=1.2[/tex].
Plugging [tex]x=1.2[/tex] in the equation we get:
[tex]f(1.2)=-2(1.2)^2+4(1.2)+2=-2\times 1.44+4.8+2=-2.88+4.8+2=3.92[/tex]
So,
[tex]f(1.2)=3.92[/tex]
Now calculating the value of [tex]f(x)[/tex] at [tex]x=3.8[/tex].
[tex]f(3.8)=-2(3.8)^2+4(3.8)+2=-2(14.44)+15.2+2=-28.88+15.2+2=-11.68[/tex]
So,
[tex]f(3.8)=-11.68[/tex]
Now that we have the values of the function at two distinct points, we can find the average by using the formula given below:
[tex]Avg= \frac{sum}{n}[/tex], where 'n' represents the number of values and that is two in our case and sum represents the sum of the values of the function.
Therefore,
[tex]Avg= \frac{3.92+(-11.68)}{2} =\frac{-7.76}{2} =-3.88[/tex]
So, the average rate of change of the function [tex]f(x)[/tex] from 1.2 to 3.8 is [tex]-3.88[/tex].

Therefore, 13b) No.
We regroup the tens place because the sum of the digits in the ones place is upto to 10.
And 13c) Yes.
We add the regrouped hundred as we regrouped the ones place.
Therefore,
13 D) Yes.
The constraints of a problem are listed below. What are the vertices of the feasible region?
Answer:
The vertices are (0,0), (3,0), (1.5,2) and (0,2.5)
Step-by-step explanation:
We are given the constraints of the problem as,
[tex]4x+3y\leq 12[/tex]
[tex]2x+6y\leq 15[/tex]
[tex]x\geq 0[/tex]
[tex]y\geq 0[/tex]
Using 'Zero Test', which states 'If after substituting (0,0) in the inequalities the result is true, the solution region is towards the origin and if the result is false, the solution region is away from the origin'
So, after plotting the graph, we see that,
The end-points of the feasible region are given by,
(0,0), (3,0), (1.5,2) and (0,2.5)
Answer:
A (0, 0), (0, 2.5), (1.5, 2), (3, 0)
