Nikos earned money over the summer mowing lawns over the 12 weeks of summer vacation he mowed a total of 132 lawns he mowed the same number of lawns each week at what rate

Nikos mowed 11 lawns each week.

Step-by-step explanation:

Let x represent number of lawn mowed per week.

We have been given that Nikos earned money over the summer mowing lawns over the 12 weeks of summer vacation, so lawns mowed in 12 weeks would be .

We are also told that Nikos mowed a total of 132 lawns, so we will equate lawns mowed in 12 weeks by 132 and solve for x as:

Now, we will divide both sides by 12 as:

Therefore, Nikos mowed 11 lawns each week.

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! )

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
