Choose the best explanation for why the graph shown is a line of best fit.
The graph shows a line of best fit because the points fit around the line.
The graph shows a line of best fit because there is a straight line.
The graph shows a line of best fit because the association is zero.
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Answers
Answer:
The graph shows a line of best fit because the points are plotted evenly above and below the line.
Step-by-step explanation:
The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have a line of best fit shown in the picture.
As we know if the slope of the line is positive then the correlation will be positive.
From the line of best fit:
Because the points are evenly spaced above and below the line, the graph displays a line of best fit.
Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Encik Ahmad builds a rectangular shaped garden
measuring 85 m long and 30 m wide. He divides the
garden into square plots to plant a variety of flowers.
Find the number of square plots that can be built if he
only wants three different square sizes.
Answers
Answer:he should build them 25x10
Step-by-step explanation:
Encik Ahmad can build 10 square plots with three different sizes.
What is Rectangle?Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.
Length of the rectangular plot = 85 m
Width of the rectangular plot = 30 m
We have to find the number of square plots Encik Ahmad can built of three different sizes.
For that first we take a 45 m length of the plot.
Divide it to three equal lengths. We get three lengths with each 15 m length.
Along the width also, divide into two equal width, each having a width of 15 m.
Each 15 m length, we will get two square plots.
Along 45 m length, we get 3 × 2 = 6 square plots.
The remaining rectangle has length 40 m and width 30 m.
Divide this length as 30 m and 10 m.
So we get a square of dimension 30 m.
Remaining is a rectangle whose remaining length is 10 m and width 30 m.
Along the width, divide into three equal widths, each 10 m.
So there we get three square plots with side length 10 m.
So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.
Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.

Sorry this got to you super late. At least others looking for the answer can find it.
The proof by S A S congruence rule is given below.
Given from fig, JK || LM.
And JK = LM
Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.
So, angle KJL = angle MLN........equation 1
Also given L is the midpoint of JN so, JL = NL.....equation 2
Now, in triangle JLK and triangle LNM
JK = LM (given)
angle KJL = angle MLN (from 1)
JL = NL (from 2)
So by S A S congruence rule, triangle JLK conguent triangle LNM proved.

The area of Canada is approximately 1×10^7 square kilometers, and the area of Mexico is approximately 2×10^6 square kilometers. The area of Canada is approximately how many times the area of Mexico?
Answers
Answer:
5 times
Step-by-step explanation:
Given that,
The area of Canada is approximately 1×10⁷ square kilometers, and the area of Mexico is approximately 2×10⁶ square kilometers.
We need to find the area of Canada is approximately how many times the area of Mexico.
Dividing both areas as follows :
[tex]\dfrac{A_c}{A_m}=\dfrac{10^7}{2\times 10^6}\\\\\dfrac{A_c}{A_m}=5\\\\A_c=5A_m[/tex]
So, the area of Canada is approximately 5 times the area of Mexico.

A small business borrows $50,000 to get started. Some of the money is borrowed at 9%, some at 7%, and some at 10% simple interest. The total of the annual interest they are charged is $4340, and the amount borrowed at 7% is two times the amount borrowed at 9%. Set up a system of equations to represent the situation, then find the amounts of money (x, y, and z) borrowed at each interest rate.
Answers
Answer: Amount borrowed at 9% = 9,428.57
Amount borrowed at 7% = $18,857.14
Amount borrowed at 10% = $ 21,714.29
Step-by-step explanation:
Formula for simple interest :
I = PRT,
P= Principal, R =rate , T= time
Let x = amount borrowed at 9%.
y = amount borrowed at 7%.
z = amount borrowed at 10%.
i.e. x+y+z= 50000 (i) [Given : amount invested = 50000]
Interest on x = x (0.09)(1) [as P=x, T=1 year, r= 0.09]
= 0.09x
Similarly
Interest on y = y(0.07)(1) = 0.07y
Interest on z = z(0.1)(1)=0.1z
Total interest = 0.09x+0.07y+0.1z = 4340 (ii)
Also, y=2x [given] (iii)
Put y=2x in (i) and (ii), we get
x+2x+z= 50000 ⇒ 3x+z=50000 (iv)
0.09x+0.07(2x)+0.1z=4340 ⇒ 0.09x+0.14x+0.1z=4340
⇒ 0.23x+0.1z=4340 (v)
Multiply 10 on both sides of (v)
2.3x+z=43400 (vi)
Eliminate (vi) from (v)
0.7x=6600
⇒ x= 9,428.57
From (iii), y= 2(9428.57) =18,857.14
From (vi),
2.3(9428.57)+z=43400
⇒ 21685.71+z=43400
⇒ z= 43400-21685.71
⇒ z=21714.29
Hence, Amount borrowed at 9% = 9,428.57
Amount borrowed at 7% = $18,857.14
Amount borrowed at 10% = $ 21,714.29

Answers
The side given is 110*, and the side underneath that is 90*. If you add it together, That's 200*. Due to the sum property of a quadrilateral, we know that the angles must add up to 360* in total. So, we can simplify it as following.
(2x) + (x+10) = 360-200
2x + (x+10) = 160
2x + x = 160-10
2x + x = 150
x = 50

X/2 = 24.
You can now multiply by 2.
X=48
what is the y and x intercept of 15x + 20y =1800?
Answers
Which means that the x intercept is 120 and the y intercept is 90.
20y = 1800
Divide by 20 on both sides
y = 90
15x = 1800
Divide 15 on both sides
x = 120
