Answer:the bottom is 24 and the left is -12
Step-by-step explanation:
Answer:
y-1=0
Step-by-step explanation:
I'm going to write into y=mx+b form first.
m is the slope and b is the y-intercept.
First step is to find the slope.
To find the slope given two points you can use m=(y2-y1)/(x2-x1).
Instead, I like to line up the points and subtract vertically. Then put 2nd difference on top of 1st difference.
Let's do that:
(-2,1)
- (2,1)
--------
-4, 0
The slope is 0/-4=0. That means the line is horizontal and is of the form y=a number.
If you look at the points, you see the y-coordinate doesn't change. The y-coordinate is always 1. So the equation for the line is y=1.
If we subtract 1 on both sides we get y-1=0.
So general form is Ax+By+C=0 which is why I decide to move the one on the other side of the equation.
If I had noticed earlier that the y-coordinates were the same I would have stopped and say y=whatever y-coordinate I seen. However, I really didn't take notice of that until after I found the slope.
Part A
If 4 candidates were to be selected regardless of gender, that means that 4 candidates is to be selected from 12.
The number of possible selections of 4 candidates from 12 is given by
Therefore, the number of <span>selections of 4 candidates regardless of gender is 495.
Part B:
</span>
<span>If 4 candidates were to be selected such that 2 women must be selected, that means that 2 men candidates is to be selected from 8 and 2 women candidates is to be selected from 4.
The number of possible selections of </span><span>2 men candidates from 8 and 2 women candidates from 4 is given by
</span><span>
Therefore, the number of selections of 4 candidates </span><span>such that 2 women must be selected is 168.</span>
Part 3:
If 4 candidates were to be selected such that at least 2 women must be
selected, that means that 2 men candidates is to be selected from 8 and 2
women candidates is to be selected from 4 or 1 man candidates is to be selected from 8 and 3
women candidates is to be selected from 4 of <span>no man candidates is to be selected from 8 and 4
women candidates is to be selected from 4.
The number of possible selections of </span>2 men candidates from 8 and 2 women candidates from 4 of <span>1 man candidates from 8 and 3
women candidates from 4 of no man candidates from 8 and 4
women candidates from 4 is given by
</span><span>
Therefore, the number of selections of 4 candidates </span><span>such that at least 2 women must be
selected is 201.</span>
The answer is 114 because 1.5 x 2=3 3.2 x 5 =16 19 x 6=114
