question a company determines the mean and standard deviation of the number of sick days taken by its employees in one year. which of the following is the best description of the standard deviation?

Answers

Answer 1

A company determines the mean and standard deviation of approximately the mean distance between the number of sick days taken and the mean number of sick days taken by all employees.

What is standard deviation?

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Think about the following data: 2, 1, 3, 2, 4. The average and the total square of the observations' departures from the mean will be 2.4 and 5.2, respectively. This means that (5.2/5) = 1.01 will be the standard deviation.

Answers

In the given figure we see the sketch of a pavement serviceability curve, label the axes, and indicate initial and terminal serviceability.

To fulfill the requirements of the Road Test, rather ordinary terms were given specific definitions as follows:

Present Serviceability: the ability of a specific section of pavement to serve highspeed, high-volume, mixed (truck and automobile) traffic in its existing condition. (Note that the definition applies to the existing condition that is, on the date of rating not to the assumed condition the next day or at any future or past date.)

This definition applies to the Road Test and can apply to any primary highway system, the system would easily be modified for use with city streets, farm roads, etc. Obviously, serviceability must be defined relative to the intended use of the road.

A wave with a wavelength of 3 m travels with a frequency of 450 Hz. What is its speed?

Answers

The speed of the wave is 1500m/s

What is the speed of a wave?

The speed of a wave is determined by its wavelength and frequency. It is measured in meter per seconds. It is calculated from the expression speed= frequency ×wavelenghth. For example, if a wave has a wavelength of 5m and a frequency of 500 Hz , it's velocity is 500×5 =2500m/s

Similarly, the wave in question is of wavelength 3m and frequency 450 Hz , therefore it's speed will be calculated as ;

speed = frequency × wavelength

speed = 450×3= 1500m/s.

therefore the speed of the wave is 1500m/s.
