PLSSS I REALLY NEED HELP!!!!

netineya [11]

Angle 1 = 115°.

Because angle 4 = 65°, we know that the angle on the other side on 4 (with no number on it) must equal 180° when added to 65°. This is because they are supplementary angles, meaning that they add up to 180°. So if you do 180°-65°, you should get 115°, which is the measure of that angle.

Since the lines are parallel, that means that angle 1 and the angle outside of 4 must be equal, which means that angle 1 = 115°.

Hope this helps!

The State Education Department requires local school districts to keep these records on all students: age, race or ethnicity, da

IgorC [24]

Answer:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level

Step-by-step explanation:

A Categorical variable is a non numerical variable, and usually is defined as "a variable that allows to assign categories but we cannot clearly order the variables".

If a variable is not Categorical can be ordinal or or numerical.

Ordinal when we can create a order from the data. And numerical when is not categorical or ordinal.

1.Reading Test Score

False, usually the scores are quantitative or numerical variable since are measured on units..

2.Race or Ethnicity

True, is categorical variable since we don't have an order for this.

3.Disabilities or Special Needs

True, we can consider this variable as categorical since we don't have an order and can't be expressed in numerical terms.

4.Age

False, is a quantitative variable or numerical

5.Mathematics Test Score

False the scores represnt a numerical variable.

6. Days Absent

False, that can be considered as quantitative if we count the days absent

7.Current Grade Level

True. That can be considered a categorical variable since we can't express this variable with numbers.

So then the correct choices are:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level

Write the augmented matrix of the system of equations given below. (10 points)

Nat2105 [25]

The augmented matrix of the system of equations is $\left[\begin{array}{ccc}-2&2&-1\\-3&-1&1\\-1&3&-2\end{array}\right] \left[\begin{array}{c}13&7\\0\end{array}\right]$

<h3>How to determine the augmented matrix?</h3>

The system of equations is given as:

-2x + 2y - z = 13

-3x - y + z = 7

-x + 3y - 2z = 0

Remove the variables x, y and z

-2 2 -1 13

-3 -1 1 7

-1 3 -2 0

Express as matrix

$\left[\begin{array}{ccc}-2&2&-1\\-3&-1&1\\-1&3&-2\end{array}\right] \left[\begin{array}{c}13&7\\0\end{array}\right]$

Hence, the augmented matrix of the system of equations is $\left[\begin{array}{ccc}-2&2&-1\\-3&-1&1\\-1&3&-2\end{array}\right] \left[\begin{array}{c}13&7\\0\end{array}\right]$
