43. If L is the midpoint of KN and MP, which
method can be used to prove the triangles are
congruent?
M
K
A. Side-Side-Side
B. Side-Angle-Side
C. Angle-Side-Angle
D. Angle-Angle-Side
Answer:
Side-Angle-Side
Step-by-step explanation:
See attachment for figures
Given
Midpoint L
Lines KN and MP
Required
Which method proves the congruency of the triangles
Since L is the midpoint, then the following relationship exists:
KL = NLML = PLThis implies that two sides of both triangles are equal
Also, because KN is a transversal of MP and vice versa, then angles KLM and PLN are equal
Conclusively, 2 corresponding sides and 1 corresponding angle have been proven to be equal.
Hence, the method that prove that the triangles are equal is Side-Angle-Side (SAS)

is the number 27 prime composite or neither
Answer:
Composite
Step-by-step explanation:
3 x 9= 27
So 27 have more than 2 factors making it a composite number
Hello there!
:)
27 is composite
Its factors are 1, 3, 9 and 27.
Keep in mind that if a number has more than 2 factors (3 or more), then the number is composite.

solved using long division
Whats the slope of the line?
Answer:
-2/4
Step-by-step explanation:
using the rise over run method, you can count how many units up you have to go to get from one point and how many units over. To go from one point on the graph to another, you have to go up 2 units and left 4 units. It is a negative slope since you have to go to the left.
Answer: y= negative 1 over 2 minus 7

Step-by-step explanation:
...............i think
Answer:
63/10 would be a simplified fraction
Step-by-step explanation:
You convert 6.30 to a mixed number by placing the numbers right of the decimal over 10, reduce the fraction, then convert it to ana improper fraction by multiplying the denominatior by the whole number and adding the numerator to get a new numerator. You then place this over the original denominator

Complete the table below for the equation y = x^2 + 2x - 1. Then, graph the equation on the provided graph grid.
Answer:
y = x^2 + 2x - 1
x = -4
y = -4^2 + 2(-4) - 1
y = 16 + (-8) - 1
y = 7
x = -3
y = -3^2 + 2(-3) - 1
y= 9 + (-6) - 1
y = 2
x = -2
y = -2^2 + 2(-2) - 1
y = 4 + (-4) - 1
y = -1
x = -1
y = -1^2 + 2(-1) - 1
y = 1 + (-2) - 1
y = -2
x = 0
y = 0^2 + 2(0) - 1
y = 0 + 0 - 1
y = -1
x = 1
y = 1^2 + 2(1) -1
y = 1 + 2 -1
y = 2
x = 2
y = 2^2 + 2(2) - 1
y = 4 + 4 - 1
y = 7
The data is given as follow. xi 2 6 9 13 20 yi 7 18 9 26 23 The estimated regression equation for these data is = 7.6 + .9x. Compute SSE, SST, and SSR (to 1 decimal). SSE SST SSR What percentage of the total sum of squares can be accounted for by the estimated regression equation (to 1 decimal)? % What is the value of the sample correlation coefficient (to 3 decimals)? Check My Work
Answer:
SSE = 127.3
SST= 281.2
SSR = 153.9
R² = 0.5473
% = 54.73%
r= +0.7398
Step-by-step explanation:
xi yi Y^ (Yi-Y^)² (Yi-Y`)²
2 7 7.6 + 0.9(2) (7-9.4)² (7-16.6)²
= 9.4 = 5.76 92.16
6 18 7.6 + 0.9(6) (18-13)² (18-16.6)²
= 13 =25 1.96
9 9 7.6 + 0.9(9) (9-15.7)² (18-16.6)²
= 15.7 =44.89 57.76
13 26 7.6 + 0.9(13) (26-19.3)² (18-16.6)²
= 19.3 = 44.89 88.36
20 23 7.6 + 0.9(20) (23-25.6)² (18-16.6)²
= 25.6 = 6.76 40.96
∑50 83 83 127.3 281.2
Y~= ∑yi/n= 83/5= 16.6
SSE = ∑ (Yi-Y^)² = 127.3
SST= ∑(Yi-Y`)²=281.2
SST = SSR + SSE
SSR = SST- SSE
= 281.2- 127.3= 153.9
Co -efficient of determination= R² = SSR/ SST= 153.9/ 281.2= 0.5473
The regression equation is explained by 54.73 % of the total sum of squares.
The linear correlation coefficient is the square root of the co -efficient of determination
r= ±√r²= √0.5473= +0.7398
We only consider the positive value for the linear correlation coefficient to be positive.

Write the equation of the ellipse with center at the origin, a vertex at (5,0), and focus at (-4,0)
Answer:
a
just did the quick check
The equation of the ellipse with a center at the origin, a vertex at (5,0), and a focus at (-4,0) is x²/5² + y²/3² = 1.
What is an ellipse?The collection of all points on an XY-plane whose distance from two fixed points (referred to as foci) adds up to a constant value is an ellipse if we speak in terms of locus.
Ellipse has two foci or focal points.
Directrixes are used to describing fixed distances.
The ellipse's eccentricity ranges from 0 to 1.
The sum of the individual distances between the two focus points of an ellipse is constant.
An ellipse has a center, a major axis, and a minor axis.
Given, An ellipse with a center at the origin, a vertex at (5,0), and a focus at (-4,0).
We know the equation of an ellipse is x²/a² + y²/b² = 1.
We also know that c² = a² - b².
(-4)² = 5² - b².
b² = 25 - 16.
b² = 9.
b = 3.
So, the equation of the given ellipse is x²/5² + y²/3² = 1.

Can someone help me solve this expression?
Answer:
2x-12
Step-by-step explanation:
First you distribute the -2 to the x and +3
this will make you expression be:
4x-6-2x-6
you then do -6+-6
this will make your expression be:
4x-12-2x
After you get this you have to combine like terms. the like terms in the expression are the two with x being you variable. 4x and -2x.
Once you have combined like terms your solution should be:
