Answer:

A. The explanatory variable is the number of items viewed. This explanatory variable is quantitative.

Step-by-step explanation:

The variable that we can change is called the Explanatory Variable.

The Response variable depends upon the explanatory variable, as we change the value of the explanatory variable the value of the response variable is also get changed.

When the data is in the form of numeric, it is called quantitative.

When the data is not in the numeric form, it is called qualitative.

Here, we have to determine which web page design is better and it depends on the number of the item viewed by a visitor to that site.

Thus, the Explanatory variable is the "number of items viewed".

and the number of items viewed is numeric data, so it is quantitative.

Hence, option (A) is correct.

Is x ^ 2 + y ^ 2 = 6 a function?
oee [108]

Answer:

not a function

Step-by-step explanation:

for example

In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.

For x2+y2=9

XXXXif (for example) x=0

XXXXthere are two values for y (namely +3 and −3) which satisfy the equation

and therefore the equation is not a function.

How do You do solving system of equations by solving for a variable
In-s [12.5K]
Well, you have to do it with the substitution method now it's not easy, it takes some time to get used to it. I'm not really sure how to explain it but if you go on Khan Academy it will show you how to do it.

In 2010, the population of Kingsford was 8000. By 2014 the population had increased by 15% and 2/5 of the population was age 12
Anastasy [175]
<h2>Hello!</h2>

The answer is: The population age 12 or under was 3680.

<h2>Why?</h2>

If in 2010 the population of Kignsford was 8000, and by 2014 the population had increased by 15% we need to calculate the total population and then, calculate how many people was age 12 or under.

We must remember that we cannot work with percentage values, so, to make 15% a real number, we need to divide it by 100:

15(Percentage)=\frac{15}{100}=0.15

So,

Calculating the population by 2014, we have:

Population_{2014}=Population_{2010}+ Population_{2010}*0.15

Then, substituting we have:

Population_{2014}=8000+ 8000*0.15=9200

Now, calculating the population that was age 12 or under, knowing that it was 2/5 of the total population, we have:

Population=TotalPopulation*\frac{2}{5}\\\\Population=9200*\frac{2}{5}=3680

So, the population age 12 or under was 3680.

Have a nice day!
