Using sampling concepts, it is found that the most representative sample of the population of interest is given by:
50 randomly selected employees at the company.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which has to involve all groups in the population.
In this problem, all employees have to be considered, no matter their department or experience on the company, hence the most representative sample of the population of interest is given by:
50 randomly selected employees at the company.

When you're drawing an inequality on a number line there are a few things to focus on:
- Whether your variable is greater than or less than the number
- Whether it can be equal to the number or not
If it can be equal to the number your first dot will be filled in, if not it will be hollow
When it's less than it means you're moving to the left on your number line, if it's greater than you move right

Answers
Answer:
The GCF is 3.

If y varies jointly as x and z when x = 5, y = 80, and z = 8, what is y when x = 16 and z = 2?
Type your answer
Answers
Hey there!
Let's make an equation
⇒y = (a)(x)(z)
y = 80x = 5z = 8⇒ 80 = a(5)(8)
⇒ 80 = a(40)
⇒ 80 = 40a
Divide both sides by 40
⇒40a/40 = 80/40
⇒a = 80/40
Therefore, a = 2
Let's substitute into first equation
⇒y = (2)(16)(2)
y = 64
So, y = 64

Determine whether one figure is a dilation of the other. Complete the justification.
Quadrilateral DEFG has side lengths of 16 m, 32 m, 28 m, and 12 m. Quadrilateral D'E'F'G' has side lengths of 44 m, 88 m, 77 m, and 33 m.
The figure D' E' F' G' (is/is not) a dilation of the figure D E F G. Thr ratios of the lengths of the corresponding sides (are not/are) equal.
Answers
Answer:
is a dilation
Step-by-step explanation:
One of the triangles will be a dilation of the other if corresponding sides have the same ratio. When given a series of side lengths, there are a couple of ways you can determine if the ratios are the same.
compute the ratio of the side of one figure to the corresponding side of the other figureput corresponding side lengths in order around the figure, and remove any common factor from their values.Sometimes the latter approach is easier.
__
DEFG ratios are 16 : 32 : 28 : 12 = 4 : 8 : 7 : 3 . . . . . . remove a factor of 4
D'E'F'G' ratios are 44 : 88 : 77 : 33 = 4 : 8 : 7 : 3 . . . . remove a factor of 11
The figure D'E'F'G' is a dilation of the figure DEFG. The ratios of the lengths of the corresponding sides are equal.
Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,000 feet wide .If astin's replica has a width of 60 centimeters, what is the height of his empire state building replica rounded to the nearest centimeter?
Answers
Answer: 14cm
Step-by-step explanation:
From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide
We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet
= 60:6000
= 1:100
Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:
= 1423/100
= 14.23cm
= 14cm approximately

Step-by-step explanation:
The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.
3(p − 4) = 3p + 3 × (-4) = 3p - 12
His attempt is
3(p - 4) = 3p - 4
He did multiply 3 by p, but h did not multiply 3 by -4.
