Answer:
As shown in picture:
A(-4, 1)
Z(-2, 3)
P(3, -4)
The length of AZ is calculated by:
L = sqrt((-4 - -2)^2 + (1 - 3)^2) = 2.83
The length of AP is calculated by:
L = sqrt((3 - -4)^2 + (-4 - 1)^2) = 8.60
THe length of ZP is calculated by:
L = sqrt((3 - -2)^2 + (-4 - 3)^2) = 8.60
=>Perimeter of triangle AZP is calculated by:
P = AZ + AP + ZP = 2.83 + 8.60 + 8.60 = 20.3
Hope this helps!

Answer:
B
Step-by-step explanation:
y=x you can imagine by drawing graph
I'd say the bottom answer is the best answer
The equation in slope-intercept form is:
Further explanation:
The standard slope-intercept form is:
Given equation is:
In order to bring the equation in slope-intercept form we have to isolate y on left hand side of equation
So,
<u>Adding 2x on both sides</u>
<u>Dividing both sides by 3</u>
<u>Simplifying</u>
The equation in slope-intercept form is:

The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.
Given:
Random number=10
mean of x=2
population=125
mean of p=2.7
Using this formula
Sampling error=x− μ
Where:
x= sample mean=2
μ=population mean=2.7
Let plug in the formula
Sampling error=2-2.7
Sampling error=-0.7
Inconclusion the sampling error is A.-0.7.
