Need the answer and work to number 3 ASAP test is timed

5

We use the Pythagorean Theorem

a(2) + b(2) = c(2)

We know c = 13, and a = 12

So,

12(2) + b(2) = 13(2)

144 + b(2) = 169

Move 144 over the = sign

b(2) = 169 - 144

b(2) = 25

Square root of 25 = 5

5 is your base!

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

happy to
