Classify the random variables below according to whether they are discrete or continuous.

(a) the time it takes to fly from city upper a to city upper b.
(b) the time it takes for a light bulb to burn out.
(c) the number of people with blood type upper a in a random sample of 42 people.
(d) the amount of snowfall.
(e) the number of points scored during a basketball game.

a) Continuous

b) Continuous

c) Discrete

d) Continuous

e) Discrete

Step-by-step explanation:

Discrete variable

Discrete variables are numerical variables that have a countable number of values between any two values. A discrete variable is always numerical. For example, the number of people with blood type Upper A in a random sample of 42 people.

Continuous variable

Continuous variables are numerical variables that have an infinite number of values between any two values. A continuous variable can be numeric or date / time. For example, the time it takes to fly from City Upper A to City Upper B.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
