Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite. When working with the graph of y = f (x), replace x with -x. Reflection in y = x: When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places.

Positive Correlation - data is increasingNegative Correlation - data is decreasingNo Correlation - data is scatteredStep-by-step explanation:
According to the given graph, we see that our data is increasing. Therefore, there will be a positive relationship in the graph.
∴ Answers C and D are eliminated.
We also see that we can draw a best line of fit in the graph. Since we can approximate this data using a linear line, our answer choice would be B.

A box-and-whisker plot. The number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 17. A line divides the box at 15.
Answer:
its C
Step-by-step explanation:
The box plot which correctly displays the data set with the given values is A. The number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.
What is Box Plot?Box plot, which is also known as box and whisker plot, is a method of graphically representing the measures like minimum, maximum and the quartiles of the data set.
Here three box and whiskers plots are given.
We have to find the box plot where,
Maximum point = 24
Minimum point = 3
Median = 15
Upper quartile = 19
Lower quartile = 6
Here the range of the whiskers depicts the maximum and minimum point.
So, the whisker must range from 3 to 24.
The range of the box depicts the quartile range.
So box must range from 6 to 19.
A line will be dividing in between which depicts the median.
So the line must be at 15.
Hence the correct plot is the number line goes from 0 to 25. The whiskers range from 3 to 24, and the box ranges from 6 to 19. A line divides the box at 15.

This trapezoid represents the base of a right prism that has a surface area of 2112 square feet.
What is the height of the prism?
Enter your answer in the box.
ft
The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter (h=3/p ft).
The surface area of the right prism is 2112 sq feet.
The length of two parallel sides of the trapezoid is 31 feet and 13 feet and the height is 16 feet.
What is the surface area of the right prism?If the side edges of a prism are perpendicular to its ends or the base, it is called a right prism.
The surface area of the right prism is 2×base area+ perimeter×height
area of base or trapezoid = [tex]\rm \frac{1}{2} \times (sum \: of \: parallel \: sides) \times h[/tex]
[tex]\rm \frac{1}{2} \times (13+31) \times 16\\=352\: ft^{2}[/tex]
The surface area of the right prism = 2B ×Ph

S = 15.47 units
Step-by-step explanation:
First, convert the degree angle into radians:
68° × (π/180) = 1.19 rad = theta
The arc length S is given by
S = r × theta
= (13 units)(1.19 rad)
= 15.47 units
Answer:
15.43
Step-by-step explanation:
The formula = angle / 360 × circumference
= angle / 360 × pi diameter
= 68 / 360 × pi × 13 + 13
= 68 / 360 × pi × 26
= 17 / 19 × pi × 26
= 221 / 45 pi

Step 2: Subtract the equations.
[tex]4x-4y=52[/tex]

[tex]\underline{4x+2y=10}[/tex]
[tex]-6y=42[/tex]
[tex]\begin{bmatrix}4x+2y=10\\ -6y=42\end{bmatrix}[/tex]
Step 3: Solve -6y=42
[tex]y=-7[/tex]
For 4x+2y=10 plug in y=-7
[tex]4x+2(-7)=10[/tex]
Simplify.
[tex]4x-14=10\\4x-14+14=10+14\\4x=24\\x=6[/tex]

Given m||n, find the value of x.
kt
(7-10)
(6x-5)°
Answer:
15
Step-by-step explanation:
So, leets look at the graph.
We can see that the lines being solved for tecnically make up 180 degrees.
This is because the value of the angles on line m are equal to the value of the angles on line n.
So, we know that the total line, 180 degrees, is 7x-10, and 6x-5.
Lets combine these two equations, and subtract them from 180 degrees to solve for x:
7x-1+6x-5
=
13x-15
Now to solve for x:
13x-15=180
Add 15 to both sides to get 13x alone:
13x=195
Then divide both sides by 13 to get x alone:
x=15
So our value of x is 15!
Hope this helps! :)

Measure of Arc JM = 160°
Step-by-step explanation:
We know that the sum of the measures of the angles within a circle all add up to 360°, so we can say:
(53) + (79) + (68) + (Arc JM) = 360
200 + Arc JM = 360
Arc JM = 360 - 200
Arc JM = 160

Answer:
mJM = 360 - (53 + 79 + 68)
mJM = 360 - 200
mJM = 160º

A laundry basket contains 8 white t-shirts and 6 black t-shirts. What is the probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back?
Answer:
30/182 = 15/91.
Step-by-step explanation:
PROBABILITY: the likelihood of an event.
There are a total of 14 shirts in the basket.
Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.
The probability of picking a black shirt is 6 in 14, or 6/14.
The probability of picking a white shirt is 8 in 14, or 8/14.
WITHOUT REPLACING: This means that you take one without putting it back. (There will be one less).
6/14 × 5/13 = 30/182.
30/182 = 15/91.
The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back is 15/ 91.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
There are a total 14 shirts in the basket.
Out of the total of 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.
The probability of picking a black shirt = 6/14.
The probability of picking a white shirt = 8/14.
The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back
= 6/14 × 5/13
= 30/182.
= 15/91.
