Answer:
a. The fuel efficiency (mpg) of an automobile is a continuous variable
b. The amount of rainfall at a particular location during the next year is a continuous variable
c. The distance that a person throws a baseball is a continuous variable
d. The number of questions asked during a 1-hr lecture is a discrete variable
e. The tension (in pounds per square inch) at which a tennis racket is strung is a continuous variable
f. The amount of water used by a household during a given month is a continuous variable
g. The number of traffic citations issued by the high- way patrol in a particular county on a given day is a discrete variable
Step-by-step explanation:
<em>Continuous </em>variables assign values in a range of infinitely many values, while <em>discrete</em> variables are countable.
<em>Continuous variables</em> in the above can assume real numbers and there are infinitely many real numbers between any two real numbers.
<em>Discrete variables </em>above can be counted in the given time interval.
1: (pi)5^2 = 78.54 then multiply that by 11 and you get 863.94
2: (pi)13^2= 530.93 then multiply that by 8 and you get 47247.44
3. (pi)18^2= 1017.88 then multiply that by 22 and you get 22393.36
I think the answer is the first one and the last one .
