Answer:
Second Option

Step-by-step explanation:
To simplify the expression you must multiply the numerator and the denominator of the fraction by the conjugate of the denominator.
If you have an expression of the form
then its conjugate will be 
The result of that multiplication will be

Therefore we have the expression

By multiplying by the conjugate of the denominator we have

Answer:
greater than 1
Step-by-step explanation:
its greater because 1.01 is greater than 1

where

is the CDF for

.
By symmetry of the distribution, you then have
the two integers 87 between is 86 87 89
X = 20
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20
