Answer: The methods that are fair include __A, B and C__ because __D__ is flawed due to increased chances of winning based on one's skill, ___F___ is flawed due to poor randomization, and ___E___ is flawed due to unequal probabilities of winning and losing.
Step-by-step explanation:
Answer:
y = 2x - 10
Step-by-step explanation:
Slope-intercept form is...
y = mx + b
To get the slope, you have to use the formula...
(y2 - y1) / (x2 - x1)
In this case,
y2 = 2
y1 = 10
x2 = 6
x1 = 10
So...
(2 - 10) / (6 - 10)
= -8 / -4 = 2
Therefore, slope is 2
y = 2x + b
Using any of the two x and y value provided, input the values in the equation
(I'm going to use 6,2)
2 = 2(6) + b
2 = 12 + b
b = -12 + 2
b = -10
Put this all together...
y = 2x - 10
Hope this helps :)
Let me know if there are any mistakes!!
D) (-2,3)
-2 is the x-value
3 is the y-value
If you look at the graph on the x-axis (horizontal line) the numbers are increasing and decreasing by 1.
Since the point of intersection (big blue dot) is on the left side of 0, it falls directly at the -2 mark
As for the y-axis (vertical lines) the numbers also increase and decrease by 1. The point of intersection falls above 0 at +3
Therefore your point of intersection is (-2,3)
to get the equation of any straight line, we simply need two points off of it, so let's use the points in the picture below.
now, if we use the last point from the table, namely (x , 17), we can see that x = x and y = 17, so let's plug those in the equation
![(17)-5=2(x-1)\implies 12=2x-2\implies 14=2x\implies \cfrac{14}{2}=x\implies 7=x \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (7~~,~~17)~\hfill](https://tex.z-dn.net/?f=%2817%29-5%3D2%28x-1%29%5Cimplies%2012%3D2x-2%5Cimplies%2014%3D2x%5Cimplies%20%5Ccfrac%7B14%7D%7B2%7D%3Dx%5Cimplies%207%3Dx%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%287~~%2C~~17%29~%5Chfill)
A) the standard of error would be that all the apartment costs would have a plus/minus of $80 so therefore the data received would be inaccurate.
