Complete question;
<em>The distribution of lengths of salmon from a certain river is approximately normal with a standard deviation of 3.5 inches. If 10 percent of salmon are longer than 30 inches, which of the following is closest to the mean of the distribution? 26 inches A 28 inches B 30 inches C 33 inches D 34 inches</em>
Option B is correct. The value that is closest to the mean of the distribution is 30inches.
The formula for calculating the z-score is expressed as:

Given the following parameters

If 10 percent of salmon are longer than 30 inches, then:
Using the z table to get the value corresponding to the mean area 0.1.
- The required z-score will be -1.285
Substitute the resulting parameters into the formula to get the mean of the distribution.

Hence the value that is closest to the mean of the distribution is 30inches.

Answer:
-45, 1, 4, 5, 9
Explanation:
The first argument value, -5, is less than -1, so the first section of the function definition is used. f(-5) = 9(-5) = -45.
The 2nd to 5th argument values are in the interval [-1, 3], so the second section of the function definition is used.
The last argument value, 6, is greater than 3, so the last section of the function definition is used. f(6) = (6 -3)^2 = 9.
Function values are shown in the table attached.
