The following are examples of different types of variables. which are continuous variables?
check all that apply.
a. temperature of a hot pizza.
b. telephone number.
c. number of votes for a candidate
d. speed of a race car
e. weight of an elephant

Step-by-step explanation:

A discrete variable is a variable whose value is obtained by counting, i.e. we can find a one to one correspondence with the set of natural numbers

But a continuous variable is a variable whose value is obtained by measuring infinitely continuous values example milk in a container. ... A discrete random variable X has a countable number of possible values

Hene we find that

a) Tempeature of  a hot pizza -- continuous(since between any two different temperatures there will be infinitely more temperatures)

B.  Telephone number. -- Discrete since countable

C. Number of votes for a candidate --Discrete since countable

D. Speed of a race car   -- Continuous (As speed can take decimals, etc.)

E. Weight of an elephant--(continuous)

a) 7x=7
