Categorize the following variables as being qualitative or quantitative: (relevant section):
FrozenT [24]

Answer:

1. Quantitative

2. Quantitative

3. Qualitative

4. Qualitative

5. Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

1. Rating of the quality of a movie on a 7-point scale

It assumes numerical values, for example, 1,2,3,...

So it is quantitative

2. Age

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

3. Country you were born in

Descriptive, such as Brazil, USA, Colombia, ...

So it is qualitative.

4. Favorite Color

Descriptive, such as black, brown, red, blue

So it is qualitative

5. Time to respond to a question

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

How to solve a quadratic equation when c=0
kherson [118]
Lets say we have a quadratic equation:

3x^2 + x + 0 = 0

Now, since if we add or subtract 0 from something, the original value stays the same, which means we can write the equation as 3x^2 + x = 0 and ignore the “+0”.

In these kinds of equations, you /can/ use the quadratic formula, but theres a much quicker way. If we factor 3x^2 + x, we get x(3x + 1) = 0. Here, x has two possible values — since the result of the multiplication is 0, that means that either one expression or the other must equal 0. In essence:

If x(3x+1) = 0 then x = 0 or 3x+1 = 0
One of the solutions is that x = 0. Lets find the other.

3x+1=0
3x= -1
x = -1/3

So x1 = 0 and x2 = -1/3. So basically you solve these equations using basic factorization. :)
