Answer:

1. The independent variable is a and the dependent variable is m

2. The domain is discrete

Step-by-step explanation:

let us explain the difference between discrete or continuous domains

Discrete domain: It is a set of input values that consists of only certain numbers in an interval.

Continuous domain: It is a set of input values that consists of all numbers in an interval.

In the question

m = 3a, where

m is the amount of money m in dollars

Each customer can buy a maximum of three apps

1.

∵ m is depended on the value of 3a

∴ m is the dependent variable ⇒ (output)

∴ a is the independent variable ⇒ (input)

∴ The independent variable is a and the dependent variable is m

2.

∵ The domain the input values

∴ Each customer can buy a maximum of three apps

→ That means it is a certain numbers

∴ The domain is discrete

Which ratio is bigger 12:10 or 18:14
aev [14]

Ratios are the same as fractions.

12:10 = 12/10

18:14 = 18/14

Divide.

12/10 = 1.2

18/14 = 1.2857

1.2857 > 1.2 ∴ 18/14 is greater

-------------------------------------------------------------------------------------------------------------------

18/14 is your answer
