Answer:

the y intercept is where is starts (up and down) slope is how much you run up, or down and how much you run

Step-by-step explanation:

For example the third croses at 5 thats the y-intercept. Know notice how you go up once and run two blocks for the slope. So the slope is 1/2x.

Answer for #3 y=1/2x+5

Note. Anytime you are running down the slope will be negative. If the line points up then its positive.

Answers should be in this form: 1) positive 2. negative 3. positive 4. negative 5. positive 6. negative

Answer:

1. slope = 4 over 2(2), y int = -8

2. slope = 2 over 3 , y int = 2

3. slope = 3 over 6(1/2), y int = 5

4. slope = 1 over 3, y int = -3

5. slope = 3 over 3(1) ,y int = 0

6. slope = 2 over 3 ,y int = -4

Step-by-step explanation:

The numbers in the () is the simplified slope version if there is no () it cannot be simplified

A group consists of 6 men and 5 women. Five people are selected to attend a conference. In how many ways can 5 people be selecte

Answer:

462

1.2%

Step-by-step explanation:

Since the questions are combinations, we must apply the combination formula, which is as follows:

n C r = (n!) / (r! (n-r)!)

Because there are 6 men and 5 women, there are a total of 11 people.

Thus:

n = 11

In the first question in how many ways can 5 people be selected from this group of 11, r = 5.

Replacing in the formula:

11 C 5 = (11!) / (5! * (11-5)!)

11 C 5 = (11!) / (5! * 6!)

11 C 5 = 462

In the second question, in how many ways can 5 men be selected from the 6 men, here n = 6 and r = 5, replacing we are left with:

6 C 5 = (6!) / (5! * (6-5)!)

6 C 5 = (6!) / (5! * 1!)

6 C 5 = 6

In the last question of what is the probability that the selected group is all men, we have that it is the combination of the two previous questions. Since the total would be part A it would be the total of the combinations of choosing 5 of 11 people and part B of the 6 men that there are the combinations of choosing 5.

Divide the two values from parts A and B to get ...

(result from part B) / (result from part A) = (# of ways to pick 5 men) / (# of ways to pick 5 people)

(result from part B) / (result from part A) = 6/462

(result from part B) / (result from part A) = 0.012

In other words, the probability is 1.2%
