Devon exercised the same amount of time each day for 5

days last week. his exercise included walking and swimming.

each day he exercised, he walked for 10 minutes. he

exercised for a total of 225 minutes last week. what is the

number of minutes devon swam each of the 5 days last

week? and show how!

He spent 35 minutes swimming each day.

Step-by-step explanation:

10x5=50

The multiply by 5 is the numbers of days.

225-50=175

(The 50 minutes subtracted is the time Devon walked)

175 divided by 5 = 35

He spent 35 minutes swimming

Confirm/Check    

35 times 5 =175

( Again, The multiply by 5 is the 5 days.)

175+50= 225

Therefore, He swam 35 minutes each day and walked 10 minutes each day.

He swam 175 minutes in total and walked 50 minutes in total

Hoped This Helped!

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! )

$9.41
