Answer:
Continuous random variables: c and e
Discrete random variables: a, b, d
Step-by-step explanation:
We have to identify whether the random variable is discrete or continuous.
- A discrete variable is a variable whose value is obtained by counting.
- A continuous random variable X takes all values in a given interval of numbers.
- Thus, a continuous variable can have values in decimals but a discrete random variable cannot take values in decimals.
a. The number of statistics students now reading a book.
Discrete random variable since number of students cannot take decimal values.
b. The number of textbook authors now sitting at a computer.
Discrete random variable since number of textbooks cannot be expressed in decimals but counted.
c. The exact time it takes to evaluate 27 plus 72.
It is a continuous random variable as it may take all values within an interval of time.
d. The number of free dash throw attempts before the first shot is made.
It is a discrete random variable since the number of throws can always be whole number.
e. The time it takes to fly from City Upper A to City Upper B.
Time is a continuous random variable.
Answer:
2i-/3
Step-by-step explanation:
This question involves imaginary numbers and simplifying radicals.
Interior and exterior angle<span> formulas: The </span>sum of the measures<span> of the interior </span>angles<span>of a </span>polygon<span> with n sides is (n – 2)180. The </span>measure<span> of each interior </span>angle<span> of an equiangular n-gon is. If you count one </span>exterior angle<span> at each vertex, the </span>sum of the measures of the exterior angles<span> of a </span>polygon<span> is always 360°. Hope this helps ^^</span>
