what is the probability of selecting a red marble followed by a blue marble if you replace the marble in between drawing. a box
vredina [299]
Basically, choosing one red marble out of everything is 3 / 10 because there are 3 chances of picking the red marble and 10 marbles overall. Picking one blue marble would be 6 / 10, or 3 / 5. You would multiply these two probabilities together because they are independent of each other:

(3 / 10)*(3 / 5) = 9 / 50

The probability is 9 / 50.

What is the minimum value of the objective function C = 4x + 9y?
Elodia [21]

Answer:-24

explain how you know:

Since xy = 4, we have y=4/x. Substituting in (1) we get f(x) = 4x+(36/x) …….(2)

Differentiating we get f ' (x) = 4 - (36/x^2)…..(2)

For maxima or minima, f ‘ (x) = 0

=> 4 - (36/x^2) =0 => (4x^2 - 36)/x^2 = 0 which gives x= +/- 3

Differentiating (2), f ‘’ (x) = 72/x^3

When x= +3 , f ‘’ (x) is clearly +ve. Therefore f(x) at (2) gives minima and the minimum value is 24.

When x= -3, f ‘’ (x) is -ve. Therefore, f(x) has maxima at x= -3. The maximum value is -24.

Note: You may be surprised to observe that the minima is more than the maxima. This is due to the fact that the function is discontinuous at x= 0, the graph of f(x) comprising of two branches, one in the first quadrant giving the minima (= +24) and another in the third quadrant that gives maxima (= -24)

V=a^3
216=a^3
now by taking cubert on both sides
cuberoot(216)=cuberoot(a^3)
a=6
