algol13

Answer:

After factorizing the given expression we get the value as x(3x-1).

Step-by-step explanation:

Given:

3x^2-x

We need to factorize the given expression using GCF.

Solution:

3x^2-x

Now GCF means Greatest common factor.

From the given 2 numbers we need to find the greatest common factor.

3\times x\times x- 1 \times x

In the given expression GCF is 'x'.

Hence we can say that;

x(3x-1)

Hence After factorizing the given expression we get the value as x(3x-1).

The options for the first blank are 45, 240, 270, and 315
Schach [20]

Answer:

The solutions are <u>270°</u> and <u>450°</u>.

Step-by-step explanation:

Given:

cos\frac{x}{2} =\frac{\sqrt{2} }{2}.

So, the second and third quadrant angle to be calculated.

cos\frac{x}{2}=135

=x=270°.

And, cos\frac{x}{2}=225

=x=450°

Therefore, the solutions are <u>270°</u> and <u>450°</u>.

What is the coefficient of determination for two variables that have perfect positive linear correlation or perfect negative lin
Aloiza [94]

Answer:

r^2 = 1

Step-by-step explanation:

The computation of the  coefficient of determination for the two variables is shown below:

here the perfect positive linear correlation is r = 1

And, the negative linear correlation is r = -1

Based on this, the coefficient of determination is equivalent to the linear correlation coefficient square

r^2 = (\pm)^2 \\\\ = 1

This above describes that variation that lies between the variables as explained by the linear regression line
