20miles increased by 30%=new mileage added
20x.3= 6
6 miles more than his previous distance so...
6+20= 26

Anything times 1 = the same number so 696969x1=696969

Answer:
If 4 fish are randomly selected, what is the probability that the mean weight will be between 9.6 and 15.6 lb? Round your answer to four decimal places.
The relevant rules of exponents are
.. (t^a)^b = t^(a·b)
.. t^a·t^b = t^(a+b)
You have
.. (t^-4)^-9·t^2
.. = t^((-4)*(-9) +2)
.. = t^38 . . . . . . . . . . . selection C
