The rate of change is the slope.

First, find any two points on the line.

For my example, I will use (5, 3) and (10, 9)

Then, subtract the second point's y-value from the first point's. This is your numerator.

9-3=6

Next, do the same for the x-values. This will be your denominator.

10-5=5

Now we put it together and get a slope of 6/5, or 1 1/5.

In conclusion, the slope of my example points, (5, 3) and (10, 9), is 1 1/5.

This question is impossible to solve without knowing how long the car was driving for!

What I think you may mean is how far did the car go in one hour.

I can help you there.

The car travels 7 km in 4 hours. If we divide both sides by 4, we get 7/4, or 1.75 km, per 1 hour.

No, these questions are not the same.

Let us assume that 150 people were surveyed, and the results were that 80 are young, 70 are old, 72 drink diet cola, and 78 do not.

So, out of the people that drink diet cola, let's say only 54 out of the 72 are young....

And so out of the people that are young, those 54 out of the 80 young people drink diet cola.

This means that the hypothetical probability for a person being young, given that they drink diet cola, is 54/72, while the probability for a person drinking diet cola, given that they are young, is 54/80.

These probabilities are different, and while rarely the questions can result in the same answers, they are definitely not the same, and usually do not lead to the same probability.

Erm...

Pi is equal to approximately 3.14, but it is an irrational number.

Here are the digits I remember:

3 1/3

OR

Nice job!

1. 40-8=32 b***s given away

32/2 per friend=16 friends

2. $12-$4=$8 after minigolf

$8*2=$16 at beginning

3. 2 pieces*4 children=8 pieces

8 pieces + 10 for herself = 18 pieces

4. 400-244=156

156/2=78 years old

5. 36-16 bought=16 after sold

16*2=32 at beginning

6. 472-4 students in cars=468 in buses

468/9 buses=52 students a bus

7. 17*2=34 hats on Wednesday

34-5 bought on Tuesday=29 on Monday

8. Well, then question says that the club contributed 4. If you want to know how many slices, then...

4 pies*5 slices=20 slices

Ok. Cool. Let me do them.
