2020-2021 Algebra 1 Unit 3 Assessment 1 of 121 of 12 Items
Feature
A new educational social website called ConnectMath and ConnectScience is being adopted by BCPS. Part of reviewing the site for adoption involved analyzing the site’s member statistics.

ConnectMath: The number of visitors increased by 3 each week.

ConnectScience: The number of visitors doubled each week.

Question 2
POSSIBLE POINTS: 2
Part B

Based on the data for the first four weeks, Leo claimed that the number of visitors to each website can be modeled as a linear function of the number of weeks online. For each website, decide if Leo’s claim is correct. If it is correct, explain why. If it is not correct, explain why and describe a more appropriate model.

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! )

50-38=12
