Determine whether the quantitative variable is discrete or continuous. Volume of water in a reservoir Is the variable discrete or continuous? volume of water

The volume of water in a reservoir is a continuous variable.

Step-by-step explanation:

A discrete variable can assume only integer(countable) values. For example, 0, 1, 2,...

A continuous variable can assume decimal values. For example, 2.3

Volume of water in a reservoir

Is the variable discrete or continuous?

The volume can assume a decimal number, for example, 2.5cm³. So the volume of water in a reservoir is a continuous variable.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
