The average performance rating of the employees at Company A is 6.5 on a scale from 1 to 10 (10 being highest). The standard deviation is 2.1 The average performance rating of the employees at Company C is 7.4. Company C has a standard deviation of 6.8. It would be better to hire a random employee from Company A. Question 2 options:

Answers

Answer 1
Answer:

The best choice based on the standardsdeviation will be to hire an employee from company A.

How to illustrate the information?

From the information given, the z value to company A will be:

= (6.5 - 5.5)/2.1

= 0.7142

The z value to company B will be:

= (7.4 - 5.5)/6.8

= 0.2794

Therefore, the best choice based on the standards deviation will be to hire an employee from company A since they've higher performance rating.

Mrs. Bergstedt teaches six classes. In her first period class she has 19 students, her third period she has 13 students, her fourth period 19 students, her fifth period 9 students, her sixth period 14 students, and her seventh period 15 students. What is her average class size, to the nearest tenth

Answers

19 + 13 + 19 + 9 + 14 + 15

19 + 13 = 32
32 + 19 = 51
51 + 9 = 60
60 + 14 = 74
74 + 15 = 89

89 / 6 (the number of classes she has)
= 14.8

What is the main reason that people are hesitant to use nuclear energy a. It produces radioactive waste. b. It uses large amounts of water. c. The ore used for nuclear energy must be mined. d. It is more damaging to natural habitats than the use of coal.

Answers

Nuclear energy is FEARED due to production of radioactive waste. Expose to radioactive waste have already taken place like Fu.kushima nuclear power station (March 2011) and more famously known; Chernobyl (April 1986). Nuclear waste is dangerous for over tens of thousands of years! For humans, radioactive waste breaks up our DNA. Either damaging our cells, or MUTATING them, which eventually lead to cancer and ever death.

The main reason that people are hesitant to use nuclear energy is It is more damaging to natural habitats than the use of coal.

What is nuclear energy?

Nuclear energy refers to the energy that is obtained from the nucleus of an atom. It is the energy that that can be obtained from a fusion or a fission reaction.

However, there are many uncertainties that surround the use of nuclear energy especially the posibility of a nuclear disaster. Hence, the main reason that people are hesitant to use nuclear energy is It is more damaging to natural habitats than the use of coal.
