Answer:
(3,11)
Step-by-step explanation:
we find the vertex of
which is going to be (x,0)
and we add 11 (movement upward) so the vertex is (x,11)
vertex of g(x)
it is going to be when g(x)=0
and that only happens when x=3
so vertex (3,0)
so vertex of f(x)
(3,11)

Answer: 2.5% of people have an IQ over 126.
Step-by-step explanation:
Given: The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13.
126 = 100 + 2(13) = Mean +2 ( standard deviation)
To find : % of people have an IQ over 126.
i.e. % of people have an IQ over Mean +2 ( standard deviation).
According to the standard deviation rule,
95% of data fall within two standard deviations.
Now, 100% - 95% = 5%
and Half of 5% is 2.5%.
So 2.5% of the data lies below 2 standard deviations of mean and 2.5% of the data lies above 2 standard deviations of mean .
i.e. 2.5% of people have an IQ over 126.
