Solve for m.
m - 5= √49
a. m=2
b. m=7
c. m=12
d. m=35

C

Step-by-step explanation:

The square root of 49 equals 7

This equation can be rewritten as m-5=7

m-5=7

1) add 5 to both sides:

m=12

Nothing else can be done so m=12 is your final answer (c)

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
