3 points 13. A sports bag contains 3 tennis balls, 4 baseballs, and 8 golf balls. Each
is equally likely to be chosen. Which of the following models could be used
to simulate this situation?
O flipping a coin fifteen times
spinning a spinner with three equal sections
O choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles
rolling a number cube labeled one through six fifteen times

I dont know completely but I think chosing from marbles

I tried...

Step-by-step explanation:

I eliminated the rest of the answer

choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles

Step-by-step explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
