Step-by-step explanation:

Total marbles = 7+8+6 = 21

7 Red

8 Green

6 Blue

Probability of choosing Red = 7/21

Probability of choosing Green = 8/21

Probability of choosing Blue = 6/21

Probability of choosing Green or Blue = 8/21 + 6/21 = 14/21

Suppose xy=4 and dy/dt=-2. Find dx/dt when x=-3
nirvana33 [79]
Dy/dx = dy/dt  *   dt/dx

xy = 4

y + x(dy/dx) = 0      by implicit differentiation. 

x(dy/dx) = -y

dy/dx = -y/x

<span>dy/dx = dy/dt  *   dt/dx             dy/dt = -2
</span>
<span>-y/x = -2 *   dt/dx
</span>
y/(2x) = dt/dx

dt/dx =  y/(2x)

dx/dt = 2x/y
  
When x = -3,   xy = 4,  y = 4/x = 4/-3 = -4/3

dx/dt = 2*-3/(-4/3) = -6 *-3/4 = 18/4 = 9/2 = 4.5

dx/dt = 4.5
