Answer:
First, we have two marbles, and i guess that each one has the same probability of being picked at random (actually they have different densities, so one may have a larger probability than the other).
The possible outcomes are:
S G
S S
G S
G G
Now, suppose that we want to find the probability of the S G outcome.
In the first selection, we want to pick the silver marble, with a probability of ps,
In the second selection, we want to pick the gold marble, with a probability pg
As the events are independent, the joint probability will be equal to the product of the probabilities for each selection:
P = ps*pg
Now, if both marbles have the same probability of being picked, then:
ps = 0.5
pg = 0.5
P = 0.5*0.5 = 0.25
And this will be the same for each outcome.
Answer:
235.71cm^2
Step-by-step explanation:
Volume of cone = 1/3 pie r^2 h
1/3*22/7*5*5*9
= 235.71cm^2
Solve for x by simplifying both sides of the equation, then isolate the variable.
x=-2b/3a+d^4/3a
Answer:
18.8 miles.
Step-by-step explanation:
(b)(h)/2 = A.
In this circumstance, you are solving for h.
Isolate h.
h = 2 x A/b
Now, substitute 102.46 for A and 10.9 for b.
h = 2 x 102.46/10.9 = 2 x 9.4 = 18.8.
h = 18.8mi.
I guess its 3.5x (edited) .....
