Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
The answer is
8x^4-10x^3-3x^2
Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours

Step-by-step explanation:
Answer:
x + 4/3x^3
Step-by-step explanation:
y=1/2x^2-2/3x^-2
dy/dx=1/2(2x)-2/3(-2x^-3)
=x+4/3 x^-3
=x+4/3x^3
