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

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
