Answer:

47 Ducks and  7 piglets.

Step-by-step explanation:

Lets try 27 of each to start

Ducks Piglets  Total legs

27        27          54 + 108 = 162.  Too many

30        24          60 + 96  =  156   Too many. Increase the ducks by 10:

40        14           80 + 56  =   136.  

50          4          100 + 16  = 116 This < 122 so ducks between 40 and 50..

45           9          90 + 36 = 126  Too high so increase  ducks:

46           8          92 + 32 = 124  Close.

47           7           94 + 28 = 122.

WINSTONCH [101]

Answer:

122785 employees.

Step-by-step explanation:

Let the total number of employees be X

Given the following data;

Number of employees = 29100

Percentage = 23.7%

To find the total number of employees;

23.7/100 * X = 29100

Cross-multiplying, we have;

23.7X = 29100 * 100

23.7X = 2910000

X = 2910000/23.7

X = 122784.81 ≈ 122785 employees

Answer:

Explained below.

Step-by-step explanation:

The human resource department at a certain company wants to conduct a survey regarding worker morale. The department has an alphabetical list of all 4,502 employees at the company and wants to conduct a systematic sample of size 50.

Systematic sampling is a kind of probability sampling method in which individuals from a larger population are nominated according to a random initial point and a static, periodic interval.

(a)

A sample of size 50.

Then the value of <em>k</em> will be: k=\frac{4502}{50}=90.04\approx 50

Thus, the value of <em>k</em> is 90.

(b)

Label the employees from 1 to 4502.

And select every 90th employee.

So, the individuals who will be administered the survey are:

90th, 180th, 270th,...

First, substitute 9 for x in 7x-3: 7(9)-3 = 60. Rewrite the problem as:
