20%

Step-by-step explanation:

Probability of ordering large

= 5/(8 + 12 + 5) = 5/25 = 1/5

= 1/5 *100 = 20%

5%

Step-by-step explanation:

Total outcome is 100

Favorable outcome is 5

The probability that a customer ordered a large cold drink is

= = 5%

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
