Answer:
z-score
Step-by-step explanation:
A z score which is also termed a standard score gives an idea about how far from the mean a data point is.
It is just as stated in the question a measure of how many standard deviations the data value lies from either below or above the mean.
Answer:
b = 12 = 20.78
c = 24
Step-by-step explanation:
The sides of a 30-60-90 triangle always have the same proportion to each other. The side opposite the 30 degree angle is x, the side opposite the 60 degree angle is x and the side opposite the 90 degree angle is 2x (this side is called the hypotenuse) .
Since we know the side opposite the 30 degree angle here is 12, then we know that the side opposite the 90 degree angle is 2 times the side opposite the 30 degree angle, c = 24 units (2 x 12).
Finally, the side opposite the 60 degree angle is 12 which equals 20.78 units.
