Well, a rational decimal is like a simple 3.1 or 4.5. It just cuts off easily. Another example would be a repeating decimal like 3.333333...


An irrational decimal is like 3.1415682983523576294875 with no pattern or cutoff point.


Sorry if I am wrong.

Rolling a 6-sided die and counting the number of each outcome that occurs is a bionomial random variable. True or False? Which o
il63 [147K]

Answer:

False.

Step-by-step explanation:

This is NOT an example of a binomial random variable, because a binomial random variable can only have TWO possible outcomes: success or failure. In the case of rolling a die, there are SIX possible outcomes: 1, 2, 3, 4, 5, or 6.

So, rolling a 6-sided die and counting the number of each outcome that occurs is NOT a binomial random variable.

Hope this helps!

If 25% of n is 18, then what is 125% of n?<br><br> SHOW ALL WORK!!!!!!!!!!!!
Lorico [155]
25 % = 18
50% = 36
75 % = 54
100 % = 72 

25% x 72 = 18 therefore n = 72 
125% x 72 = 90

Therefore 125% of n is 90
