Answer:

AC = 18, EB = 5 Step-by-step explanation:In a rhombus, AE = CE, and DE = BE. However, AE or AC ≠ DE or BE.

If IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, what is the mean IQ score after the sco
lianna [129]

Answer:

\mu = 0 , \sigma=1

Step-by-step explanation:

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".  

Solution to the problem

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

X \sim N(100,15)  

Where \mu=100 and \sigma=15

If we standardize the variable with the z score given by:

Z= \frac{x -\mu}{\sigma}

We got a normal standard distribution with parameters Z\sim N (0,1)

\mu = 0 , \sigma=1
