Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0

Answer:
Step-by-step explanation:
The following angles are equivalent:
Q = U = 45°
R = T = W = 225°
S = V = 90°
X = 135°
Reflection, any rigid transformation, or any uniform dilation will not change the measures of the angles. That is, U = U', for example.
So, the true angle statements are ...
Answer:
y = 107°
Step-by-step explanation:
As you can see from the markings on the triangle, this is an isosceles triangle (two sides are congruent).
An isosceles triangle has the base angles congruent too.
So at this point,
34 = x - 5
Solve for x,
34 = x - 5
x = 34 + 5
x = 39
Now, the total angle measure of triangle is 180°.
There are two angles ready to solve for y.
34 + 39 + y = 180
73 + y = 180
y = 180 - 73
y = 107°
