Answer:
0.0319
Step-by-step explanation:
To approximate this probability, we shall be using the Bernoulli approximation of the Binomial distribution.
Let p = probability of selecting a reference book = 65% = 0.65
Let q = probability of selecting other books= 1-p = 1-0.65 = 0.35
Now, we want to find the probability that all of these 8 books to be re-shelved are reference book.
We set up the probability as follows;
P(X = 8) = 8C8 •p^8•q^0
P(X = 8) = 1 * (0.65)^8 * (0.35)^0
P(X = 8) = 0.031864481289 which is 0.0319 to 4 decimal places

An arithmetic sequence can be expressed as explicitly or recursively
The explicit formula of the sequence is 
<h3>How to determine the explicit formula</h3>
The recursive formula is given as:
Substitute 2 for n in
This gives
Calculate the common difference (d)
The explicit formula is then calculated as:
This gives
Expand
Hence, the explicit formula of the sequence is

All you have to do is the price multiplied by the amount of kg. BUT make sure that they are both in the same units, in this case they are both in kilograms. So you do 7.25x20=$145
