Shawna found out there are 4 yellow pencils for every blue pencil. write an equation for this situation. complete the table to show how many yellow pencils if there are 5,7, 9,11 or 13 blue pencils.

Step-by-step explanation:

Let f(x) be number of yellow pencils and x be number of blue pencils.

We have been given that Shawna found out there are 4 yellow pencils for every blue pencil. We can represent this information in an equation as:

Therefore, our desired equation will be: .

Now let find number of yellow pencils for the given number of blue pencils by substituting the number of blue pencils in our equation as:

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
