i dont know. Im sorry about that.
4 red, 3 blue, 3 yellow ....total = 10
P(red) = 4/10 reduces to 2/5
without replacement
P(blue) = 3/9 reduces to 1/3
without replacement
P(red) = 3/8
P( all this happens) = 2/5 * 1/3 * 3/8 = 6 / 120 reduces to 1/20 <=
Answer:Total units would be: 3+4 = 7. value of 1 unit = 28/7 = 4. ratio would be 3(4) & 4(4) = 12 & 16
Step-by-step explanation:
Answer:
, 
Step-by-step explanation:
you use the quadratic equation: (-b ± 
) ÷ 2a
in this case, a = 5, b = 5, c = 8
inside the radical will be -135, hence using 135i where 'i' equals -1
