Answer:
For 10 tosses we have that E(X)=10
Therefore E(i)= 1/10 +2/10 +3/10....10/10
This implies that 40/10=E(i)
Therefore E(10) =40/10
= 4.
Answer:
A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). It can be written as a fraction in which the the top number (numerator) is divided by the bottom number (denominator). ... Pi (π) is irrational since it cannot be written as a fraction.
Step-by-step explanation:
14*15 is 210 which his the entire area. now divide 210/20 you get 10.5 so you will need at least 11 bags
So you would do,
18 gallons of water divided by 0.5 gallons of water
if you did that correctly you should have gotten... 36 jugs
