The best answer would be D
Because Rotational symmetry is a symmetric shape that can be rotated but appear the same.
Answer:
A
Step-by-step explanation:
F test is a statistical method used to determine which models best fits the population from which the sample is derived. It is a ratio of two variances. Variance measure the rate of dispersion
The formula for calculating f-test = explained variance / unexplained variance
There are two hypothesis in an f test :
1. the null hypothesis - all slope coefficient are equal to zero
the alternative hypothesis : at least one of the slope coefficient is not equal to zero
You would divide a side of the larger rectangle by the smaller rectangle and it would give an answer of 1.5. To check if your correct times your answer by one of the sides on the smaller triangle
Answer:
x-intercept = 10
y-intercept = -8
Step-by-step explanation:
To identify the y-intercept, we will need to format the equation in the form 
. We can start by subtracting 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
The 
is representative of the y-intercept in .
Identify in the equation :
Therefore, our y-intercept is -8.
To solve for the x-intercept, replace the in the equation with a zero:
Add 
to both sides of the equation:
You can go ahead and divide 
by to get rid of the fraction:
Divide both sides of the equation by the coefficient of 
, which is 
:
Therefore, our x-intercept is 10.
Since the 90% is 63. divide it by 9. then you would get value of 7. then multiple it by 10.
which is equal to 70. so 100% is 70.
