David is building a play area for his kids. They are learning their shapes and he wants it to be an isosceles triangle with base b and height h. He is restricted to dimensions such that b + h = 25. What is the maximum area of the triangle?
A. A = 67.5

B. A = 86.125

C. A = 79.5

D. A = 78.125

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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
