For this case, we have the following equation:

\frac {3} {4} x = 9

We must find a number that when multiplied on both sides of the equation, as a result:

x = 12

So, if we multiply 9 * \frac {4} {3} = 12

Now, the left side must also be multiplied by \frac {4} {3}so as not to alter the equation:

\frac {3} {4} x * \frac {4} {3} = x

Finally we havex = 12

Thus, the number is \frac {4} {3}

Option C

Answer:

C. 4/3

Step-by-step explanation:

The original equation is [3/4]x = 9

To solve for x, you have to multiply both sides by 4/3

[4/3] ×[3/4]x = 9×[4/3]

x = 36/3 = 12

Answer: C. 4/3

In finance the notion of expected value is used to analyze investments for which the investor has an estimate of the chances ass
blagie [28]

Answer:

Step-by-step explanation:

The expected return is given as

Expected Return = SUM (Return i x Probability i). i=1,2,3.....

First investment

Probability of 0.7, it returns 60cents per dollars

Second investment

Probably of 0.3, it loses 20cents per dollar.

Expected return=(0.7×60)-(0.3×20)

Excepted return= 42-6

Excepted return=36cents

To dollars, 1cents is 0.01dollars

Then, 36cents = 0.36dollars

Expected return=$0.36
