The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders

irina1246 [14]

Using the data presented in the problem, you are asked to predict the probability that future customers will cancel their preorders. To find the probability, you have to divide the number of people who cancelled their preorders by the total number of people who preordered.

35 people / 140 people = .25 or 25% probability that the future customers will cancel their preorders.

How do I do rate of change???

Bad White [126]

Answer:

12

Step-by-step explanation:

For our problem since we only in 10 am:

I'm going to let x=4 represent the time 10:04 am

which means I'm going to let x=17 represent 10:17am.

So when x=4, y=23 miles and when x=17,y=179 miles.

You have two points.

You can use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

Or just line the points up vertically and subtract them vertically, then put 2nd difference over first difference. Like this:

( 17 , 179)

-( 4 , 23)

-----------------------

13 156

So the slope is 156/13=12 miles/hour.
