Hope this helped
We see a right triangle here.
Use the Pythagorean Theorem:
a^2+b^2=c^2
a & b=legs
c=hypotenuse
a^2+15^2=20^2
a^2+225=400
a^2=175
a=13.2287565553
a=13.2
The missing side is 13.2cm
The probabillity can be found by using binomial probability formular considering that the event is discrete in nature and there are two possiple outcomes.
Im pretty sure it would be product
Y = 7.25x
Where x = hours.
You can get this by dividing the amount by the amount of hours in each pair.
