Can I have brainliest. I need it. I friend requested you. Folooow my questions and answer them for lots of points <333
The answer is z score of 2.00 is most desirable because it is 2.00 standard deviations beyond the mean and would agree to the highest of the five diverse likely test scores. In addition, the number of standard deviations that a given value x is above or below the mean is the z score or as called as standardized value. The negative z score agrees to an x value less than the mean while a positive z score agrees to an x value larger than the mean. The more negative the z score the more the x value is under the mean and the further positive the z score the more the x value is below the mean.

Hello!
Angles 3 and 1 are vertical angles, and angles 2 and 4 are vertical angles. Vertical angles are congruent by definition, so angle 3 is congruent to angle 1, and angle 2 is congruent to angle 4.
The adjacent angles are supplementary (they add to equal 180 degrees) so you can set up an equation to solve for x.
180 = 2x + x
180 = 3x
60 = x
x = 60
To find the measure if each angle, plug in x as needed.
Angle 4 = x
Angle 4 = 60 degrees
Angle 2 = angle 4
Angle 2 = 60 degrees
Angle 3 = 2x
Angle 3 = 2(60)
Angle 3 = 120
Angle 1 = angle 3
Angle 1 = 120
I hope this helps you.
