Step-by-step explanation:
an exponential function of the form
y = a
to find a and b use ordered pairs from the table
using (0, 0.5 ) , then
0.5 = a [
= 1 ] , then
a = 0.5
so y = 0.5
using (1, 2 ) , then
2 = 0.5 = 0.5b ( divide both sides by 0.5 )
4 = b
then exponential function represented by the table is
y = 0.5

Step-by-step explanation:
Let X be the IQ
IQ is normally distributed with a mean of 100 and a standard deviation of 15.
a) the probability that this person has an IQ greater than 95
=
=62.93%
b) the probability that this person has an IQ less than 125
=4.75%
c) Sample size =500
No of people = 0.2486(500) =124.3
d)
No of persons = 0.0047(500) = 2.35
