What is the simple interest of 570, 2%, 4 years

45.6

Step-by-step explanation:

For simple interest, just multiply all of them together

note that 2% = 0.02

570(0.02)(4) = 45.6

simple interest is 45.6

oh and if you need the equation, it is p(r)t, or principle x rate x time

hope this helps

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
