Answer:

x = 18

Step-by-step explanation:

The angle vertically opposite (5x + 2) is also (5x + 2), then

(5x + 2) and (5x - 2) are same- side interior angles and sum to 180° , that is

5x + 2 + 5x - 2 = 180

10x = 180 ( divide both sides by 10 )

x = 18

For a standardized psychology examination intended for psychology majors, the historical data show that scores have a mean of 50

Volgvan

Answer:

$P(\bar X>530)=1-0.808=0.192$

Step-by-step explanation:

1) Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent the scores, and for this case we know the distribution for X is given by:

$X \sim N(\mu=505,\sigma=170)$
