John is interested in purchasing a multi-office building containing five offices. the current owner provides the following probability distribution indicating the probability that the given number of offices will be leased each year. number of lease offices 0 1 2 3 4 5 probability 5/18 1/4 1/9 1/18 2/9 1/12 if each yearly lease is $12,000, how much could john expect to collect in yearly leases for the whole building in a given year? (in dollars)
a) e(x) = $23,353.33
b) e(x) = $23,333.33
c) e(x) = $23,273.33
d) e(x) = $23,263.33
e) e(x) = $23,423.33
f) none of the above.
1. by definition, scientific notation has the following form:
a is a number between 1 and 10 but does not include 10.
b an integer.
2. when you multiply 3.25 by 7.8 the result is 25.35 and when you multiply by , you obtain , but to write ree thsult in scientific notation, the decimal point must be after the first digit. therefore, you must move the decimal point one place to the left. so, the exponent changes from 9 to 10:
i think this question needs more information.
to figure out 110% of the students who walk, we need to know how many students walked to school.

because we find the ratio of 4: 12 which is 1: 3 60 divided by 3 is 20 and so its 20 pages an hour
