Answer:

A constant is a defined value often portrayed as a number.

A variable is a value that can change and is often represented as a letter.

Step-by-step explanation:

For example:

In the equation ? = 10x + 3y + 17

10, 3, and 17 are all constants.

X and Y are both variables.

To reiterate, constants are known values that can NOT change while variables are unknown values that can change!

Voting age

Levart [38]

Answer:

$\frac{17}{64}\approx 0.27$

Step-by-step explanation:

We have been given a table to voters and their ages. We are asked to find the probability that a voter is younger than 45.

Voting age Voters

17-29 9

30-44 8

45-64 32

65+ 15

We can see from our given table that age of 17 (9+8) voters is between 17 to 44 years.

To find the probability that a voter is younger than 45, we will divide 17 by total number of voters.

$\text{Total voters}=9+8+32+15=64$

$\text{Probability that a voter is younger than 45}=\frac{17}{64}$

$\text{Probability that a voter is younger than 45}=0.265625$

$\text{Probability that a voter is younger than 45}\approx 0.27$

Therefore, the probability that a voter is younger than 45 is 0.27.
