M(x)=4x+15;m(x)=7

Answer?

M=0

Step-by-step explanation:

(M)=4M+15(M)=7

We move all terms to the left:

(M)-(4M+15(M))=0

We add all the numbers together, and all the variables

M-(+19M)=0

We get rid of parentheses

M-19M=0

We add all the numbers together, and all the variables

-18M=0

M=0/-18

M=0

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
