The following scatter plot represents the relationship between a person's weight and the number of calories the person burns in one minute of jump roping. using the line of best fit, about how many calories per minute could you expect a 75-pound person to burn while jump roping?

5
5.5
6
7

About 6

Step-by-step explanation:

Look at the 75 pound point, right between 100 and 50. Then go up until that point reaches the red line, and there's your answer!

-50/3

step-by-step explanation:

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
