Answer:
a. m<CBA = m<DBA because of the definition of an angle bisector (angle bisector cuts the angle in half) We are also told that segment BD and Segment BC are congruent.
We don't know if segment AC and AD are congruent so we can't say those angles (the other two) are congruent.
b. point A and B will stay fixed because they are colinear to segment AB (on the same line)
c. Those two are needed because If those are true we can prove that they are congruent by SAS (Side Angle Side)
d. the reflection an prove that the lines and angles are congruent.
Answer:
Below.
Step-by-step explanation:
This transformation is described by (x,y)---> (y,x).
G(4,1) ---> G'(1,4)
H(5,-4) ---> H'(-4,5)
I(2, -8) ----> I'(-8,2).
A coefficient is the number that goes with the letter such as 6x were 6 is the coefficient.
Answer:
circle=2 dots hexagon=12 dots
Step-by-step explaination
Take a look at the left hand side of the mobile you can see that 3 circles = 2 circles and two dots. Then subract two circles from either side of mobile. Then you get 1 circle = 2 dots.
Next, if you want to find out how many dots a hexagon is equal to then convert each circle into dots and you get 1 hexagon = 12 dots
The answer is 1 circle = 2 dots 1 hexagon = 12 dots
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Practice throws(X) : 4 10 6 15 0 7 11
Free throws(Y) : 8 23 9 34 5 11 27
Using the online linear regression calculator :
ŷ = 2.1559X + 0.3912
2.1559 = slope
0.3912 = intercept
X = independent variable ; y = dependent variable
The Coefficient of determination (R²) = 0.9506² = 0.9036
Quadratic model : y = 0.0961x²+0.7138x+3.8031
Coefficient of determination(R²) = 0.9739² = 0.9485
Exponential model:
a*b^x
Coefficient of determination (R²) = 0.9753² = 0.9512
The exponential model fits the data best.
