Answer:
There is a 3/5 chance of the first ball being white, and a 3/10 chance the second one is black.
Step-by-step explanation:
There are 5 balls, of which 3 are white, so you have a 3/5 chance of the first one being white. Then you have 2 white and 2 black balls. There is a 2/4 chance of picking a black ball. Multiply 3/5 and 2/4 to get 6/20, or 3/10 for choosing a white ball then a black ball.
Answer:
y= (-3x+8)/4
x = (-4 +8)/3
Step-by-step explanation:
3x + 4y = 8
-3x -3x
4y = -3x +8 divide ALL by 4
y= (-3x+8)/4
3x + 4y = 8
-4y -4y
3x = -4 +8 divide ALL by 3
x = (-4 +8)/3
The roots are-4 and 7y=x² - 3x - 28<span>The roots are
-9 and 2</span>x² = 18 - 7xThe roots are-4,and 2y = x² + 2x -8The roots are-8 and 10x² - 2x - 6 = 74<span>The roots are
-15 and-1</span>x² + 15 = - 16xThe roots are-5 and 9y=x² - 4x - 45<span>The roots are
4 and 14</span>x² - x + 56 = 17x<span>The roots are
2 and 27</span>x² - 29x = - 54
