Many states have fishing regulations that require anglers to throw back caught fish if they do not meet length requirements. For the red drum species, a caught fish must be thrown back if it is not between 21 and 28 inches long. The lengths of the red drum species of fish have an approximately Normal distribution, with a mean length of 24 inches and a standard deviation of 1.4 inches. What proportion of red drum fish must be thrown back?

 0.01827

Step-by-step explanation:

Given: The lengths of the red drum species of fish have an approximately Normal distribution, with a mean length of 24 inches and a standard deviation of 1.4 inches.

Let x=  length of the red drum species of fish

The probability that length is not between 21 and 28 inches long :

Hence, the proportion of red drum fish must be thrown back = 0.01827

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
