The answer should be 4.

First, simplify  to 4. Your problem should look like: 4 x 1. 
Second, multiply. 4 x 1 = 4 so that is your answer.

Also, 
to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like: .

scoray [572]

The two events are independent of each other.

According to the question during a game of roulette, a wheel is spun and a ball drops randomly into one of the wheel's numbered compartments. The ball can drop in any one of the wheel's numbered compartments , there is no restriction on it.

Now,  the process is repeated with another random spin. when the process is repeated the ball can drop in any one of the wheel's numbered compartments , there is no restriction on it. As the first spin  does not affect the second spin, we can conclude that these two events are  completely independent of each other.

sesenic [268]
Brief review of proportionality relationships:

When two quantities a,b are \textbf{directly} proportional, that means any change in a manifests a \textbf{direct} change (think "in the same direction") in b.

Silly example: "The more I eat, the fatter I get." Here the amount one eats is directly proportional to one's body weight.

This change isn't always one-for-one, so we introduce a constant k to account for any scaling that occurs on either variables behalf. In general, though, we can write a directly proportional relationship as a=kb.

Now, when a,b are \textbf{inversely} proportional, then a change in a manifests a change in b in the \textbf{inverse} (opposite) direction.

Silly example: "The more I eat, the less thin I get."

This time we write the relation as ab=k.

To get back to your problem: To say that the rate of change of y(x) is inversely proportional to \sqrt y is to say that there is some constant k such that

\sqrt y\dfrac{\mathrm dy}{\mathrm dx}=k

This is a separable ODE:

y^{1/2}\,\mathrm dy=k\,\mathrm dx
\displaystyle\int y^{1/2}\,\mathrm dy=\int k\,\mathrm dx
\dfrac23y^{3/2}+C_y=kx+C_x
\dfrac23y^{3/2}=kx+C
y^{3/2}=\dfrac{3k}2x+C
y=\left(\dfrac{3k}2x+C\right)^{2/3}

avanturin [10]
(2,5 x 10^-10)(7 x 10^-6) = (2.5 x 7) x 10^(-10 - 6) = 17.5 x 10^-16 = 1.75 x 10^-15
