The procedure of standardization transforms individual scores to standard scores for which we know the percentiles (if the data are normally distributed).

Standardization does this by transforming individual scores from different normal distributions to a common normal distribution with a known mean, standard deviation, and percentiles.

A standardized score is the number of standard deviations an observation or data point is above or below the mean.

The standard score of the random variable X is:

$Z=\frac{X-\mu}{\sigma}$

These standard scores are also known as z-scores and they follow a Standard normal distribution, i.e. N (0, 1).

It is provided that the height of a successful basketball player is 196 cm.

The standard value of this height is, z = 3.02.

The z-score of 3.02 implies that the player's height is 3.02 standard deviations above the mean.

Given angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

Whitepunk [10]

Answer:

y = 3

Step-by-step explanation:

*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.

5y + 10 = 28 - y

*Add y to both sides.

6y + 10 = 28

*Subtract 10 from both sides.

6y = 18

*Divide both sides by 6.

y = 3
