Probability =
(number of ways it can come out the way you want)
divided by
(total number of ways it can come out).
Total number of ways to draw a marble = 30 (marbles in the bag).
Number of ways it can succeed = 15 (number of red or green ones)
Probability = 15/30 = 1/2 = 50% .
Answer:
it would be A:55%
Step-by-step explanation
For percent, to make it easier try to turn it into a 100.
20x5=100
do the same to the 9.
9x5=45.
Now subtract 45 from 100.
100-45=55.
There was a discount of 55%.
Answer:
1/4
Step-by-step explanation:
The orange shape is 3 units tall and 4 units wide. The black shape is 12 units tall and 16 units wide. The scale factor is ...
orange/black = 3/12 = 4/16 = 1/4

Step-by-step explanation:
y'=dy/dx=d/dx(4x³+3x²-2x+9)
=(3*4x^(3-1)+2*3x^(2-1)-2*1x^(1-1)+9*0
y'=12x²+6x-2
2x = 48, 3x = 72, 4x = 96, 6x = 144
2x + 3x + 4x + 6x = 360
15x = 360
x = 24
2x = 2(24) = 48
3x = 3(24) = 72
4x = 4(24) = 96
6x = 6(24) = 144
