Kevin works as a part-time vendor selling wallets for $20 each and hats for $15 each. He needs to earn a minimum of $450 per week to cover his expenses. The inequality that represents this situation is graphed here, where x is the number of wallets sold and y is the number of hats sold.

20x + 15y ≥ 450

Determine which points are valid solutions and which are invalid, and then drag them to the correct location on the table.

Valid is (32,12) , (6,36) , (20,20)

Invalid is (-4,40) , (36,-8), (15,22.5)

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
