the distribution of lengths of salmon from a certain river is approximately normal with standard deviation 3.5 inches. if 10 per
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.

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expense
djverab [1.8K]

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

Nigerian publisher has estimated that 500,000 to 600,000 people in Africa want an anthology that includes all the works of Wole
Illusion [34]

The correct answer to this open question is the following.

Although the question is incomplete because it does not include excerpts, paragraphs, or statements, we can say the following.

The renewed interest in Wole Soyinka's works could be because he used irony and some humor to criticize social problems in Nigeria, as well as a serious criticism of Nigerian government officials, putting emphasis on military dictators.

Soyinka is a Nigerian writer that has always been interested in the social condition of the people of Nigeria under tough political and economic times. He has written many essays, poems, even plays that have exhibited in his country. That is why so many people in Africa want an anthology that includes all the works of Wole Soyinka.
