juin [17]

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:

$z=\frac{ x-\mu}{\sigma}$

Given the following parameters

$\sigma = 3.5\\x = 26in$

If 10 percent of salmon are longer than 30 inches, then:

P(x>30) = 0.1

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.

$z=\frac{x-\mu}{\sigma}\\-1.285=\frac{26-\mu}{3.5}\\-1.285 \times 3.5 = 26 - \mu\\ -4.4975 = 26 - \mu\\\mu = 26 + 4.4975\\\mu = 30.4975\\\mu \approx 30in$

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

ankoles [38]

There are different kinds of angles. The statement that will accurately correct the two-column proof is that the definition of angle on a straight line.

<h3>What is straight angle? </h3>

This is an angle whose sides sit in opposite directions from the vertex usually in the same straight line and is said to be equals two right angles.

Two angles are known to be supplementary when their measures if sum up reaches 180 degrees.

Conclusively, Looking at the angle, m∠ZRY = 180°, this is because angle ZRY is a straight angle and it is not a supplementary angle.

Therefore option A is the correct answer (Image attached)
