Kristin wants to ask the managers of the fast food restaurants in a large city “how do you retain employees? ” what condition must be true to justify surveying only a sample of the managers instead of surveying the entire population of managers? a. the population is small b. the population is diverse c. population is not the target of the survey question d. population is expensive and time consuming to survey

Option (D) is the correct answer.

Explanation:

Population includes number of people present in a region, state, or country.

So, when a survey is conducted including entire population then a lot of time gets consumed because asking questions of the survey to each and every individual very time consuming.

Also, it is very expensive as going to different places for the survey will require to pay the expenses on your own.

When a smaller group of people is surveyed like the managers in the given situation then neither it is expensive nor time consuming.

Therefore, we can conclude that the condition population is expensive and time consuming to survey, must be true to justify surveying only a sample of the managers instead of surveying the entire population of managers.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
