kozerog [31]

The following data set is A population ⇒ answer A

Step-by-step explanation:

Lets revise the definition of each choice

1. A population, is a discrete group of people, animals or things that

can be identified by at least one common characteristic for the

purposes of data collection

2. A sample is just a part of a population

3. The parameter is a fixed measure which describes the target population

Parameter is a fixed and unknown numerical value

4. A statistic is a characteristic of a small part of the population

The statistic is a variable and known number which depend on the

sample of the population

∵ All of the teachers in Gwinnett County Public Schools fill out the

survey

∴ The data set is population

The following data set is A population

If y is inversely proportional to the square root of x and y=−70 when x=49, find y if x=2401.

Dahasolnce [82]

The value of y when x= 2401 is -10

<h3>How to determine the value of x?</h3>

An inverse variation is represented as:

$y = \frac{k}{\sqrt x}$

Where k is the proportionality constant

When y = -70, x = 49

So, we have:

$-70 = \frac{k}{\sqrt {49}}$

Take the square root of 49

$-70 = \frac{k}{7}$

Multiply through by 7

k = -490

Substitute k = -490 in $y = \frac{k}{\sqrt x}$

$y = -\frac{490}{\sqrt x}$

When x =2401, we have

$y = -\frac{490}{\sqrt {2401}}$

Evaluate the square root

$y = -\frac{490}{49}$

Divide

y = -10

Hence, the value of y when x= 2401 is -10
