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

We got a normal standard distribution with parameters 

Answer:
5
Step-by-step explanation:
none of the above are true
1. intersect at x=45
so y=sqrt(2)
2. y=cscx period is doubled y=tanx
3. not the same
4. no local maximum of y=secx
minimum point of y=sinx is -1
so none of the above are true
