Answer:
C: Irrational
Explanation:
the reason i chose C because when you add a rational and irrational number together you still get a repeating number which is irrational.
For Example: Take a rational number 5 and Pi
if you ad those together 5+3.1415... you still get a repeating decimal, and repeating decimals are also irrational numbers.
Hope this helps :D
A random variable can be either discrete or continuous. It is discrete it can assume only a finite number of values, or a countable infinity of values at most.
It is continuous if it can assume values in an interval, or in general, an uncountable infinity of values.
That being said, we have:
Option A is a discrete random variable, because the number of heads in 5 throws can be 0, 1, 2, 3, 4 or 5. So, we have finitely many possible values.
Option B is a discrete random variable, because the number you roll on a die is either1, 2, 3, 4, 5 or 6. So, we have finitely many possible values.
Option C is a discrete random variable, because if there are n students in a class, the number of boys is an integer between 0 and n. So, we have finitely many possible values.
Option D is finally a continuous random variable, because the height of a 10-year-old can be any number (in a suitable range of course).
Answer:
a-n=1
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
n + 3 = 11
n = 8
Divide 4 on both sides, x=6.4/4 which is 1.6
