This question seems to have way too much information and be more confusing then it needs to be. When it comes down to it the only important information is that
<span>>The store manager decides to charge a weekly fee of $6
></span><span>Books to students for $2 per book
And the question is
></span><span>This
is a decision (fair or unfair) for the students as they will pay (more
than,the same as, less than) they would pay to rent four books.
Answer:
(I think) the decision is fair for the students as they will pay less than they would pay to rent four books.

1/10 the value of 237 means we must multiply 1/10 by 237
1/10 * 237 = 23.7
Hope this helps!
Answer:
3/10 liter
Step-by-step explanation:
Assuming your description means that 4/3 liters of punch includes 2/5 liters of water, then the fraction of punch that is water is ...
(2/5)/(4/3) = (2/5)(3/4) = 3/10
3/10 of a liter of water is used in each liter of punch.
Answer:
a) P = 0.039
b) The expected number of days is 10 days.
Step-by-step explanation:
The most appropiate distribution to use in this case is the geometric distribution, in order to calculate the probability of a success after k failure trials.
The probability of success, as each of the 10 products are assumed to have fair probabilities, is:

Then, the probability that our product is not selected any given day is:

a) The probability that exactly this product is selected exactly 10 days from now is the probability that is not selected (probbility q) for the next 9 days and selected (probability p) at the 10th day:

b) The expected number of days is calculated as:

You can divide the two values A = diameter of bacterium B = diameter of virus A/B = (10^(-6))/(10^(-7)) A/B = 10^(-6-(-7)) A/B = 10^(-6+7) A/B = 10^(1) A/B = 10 Since the ratio of the two diameters is 10, this means that the diameter of the bacterium is 10 times greater than that of the virus.
