Jane has several legal documents to type. Jane completes an average of 7 documents per 15 minutes. Her completion of one documen
t is independent of any other one.
a) Let N be the number of documents Jane completes between 9:00am and 10:00am. What are the distribution, parameter(s), and support of N?
b) Determine the probability that Jane completes 30 documents between 9:00am and 10:00am.
c) What is the probability that Jane completes 58 documents between 2:00pm and 4:00pm.
d) Determine the probability that Jane completes 30 documents between 9:00am and 10:00am and 40 documents between 1:00pm and 2:30pm.
e) What is the standard deviation for the number of documents Jane will complete between 3:00pm and 5:45pm?
f) If Jane is paid at a rate of 1 dollar and 25 cents per document how much can she expect to make for a day in which she has 6 and a half hours of straight typing?

Answer:
one large box equals 15.75<em>kg</em>
one small box equals 13.75<em>kg</em>
Step-by-step explanation:
First, identify your variables:
Let "l" represent the weight of one large box.
Let"s" represent the weight of one small box.
Then, stack the two equations on top of each other:
Next, multiply the first equation by 3 so we can use elimination of the "s" variable to find the "l" variable first:
Now, subtract the two equations to cancel out the s-variable and find the l-variable:
Then, substitute your l-variable in the original first equation to find the s-variable:
With all the information that is collected, you find that one large box weighs 15.75<em>kg</em> and one small box weighs 13.75<em>kg</em>.
