Next time please indicate which problem you want to work on.

One example of an equation with variables present on both sides is

y-b = m(x-a). Given the slope of a line and one point (a,b) through which the line passes, you can come up with an equation of the line.

Or, given the numeric value of y-b and that of x-a, you could obtain the slope of the line thru the points (x,y) and (a,b).

If you draw a card with a value of four or less from a standard deck of cards I will pay you $43 if not you pay me $10. Step 1.

The expected value of the game is its average earnings

The expected value of a round is $2.23
The expected value when the game is played 755 times is $1683.65

<h3>How to determine the expected value of a round</h3>

There are 12 cards with a value of 4 or less.

So, the probability of selecting a card with a value of 4 or less is:

$P(x \le 4) = \frac{12}{52}$

The probability of selecting a card with a value more than 4 is the complement of the above probability.

So, we have:

$P(x > 4) = 1 - \frac{12}{52}$

$P(x > 4) = \frac{40}{52}$

The expected value is then calculated as:

$E(x) = \frac{12}{52} * 43 - \frac{40}{52} * 10$

Evaluate

$E(x) = \frac{12* 43 - 40 * 10}{52}$

$E(x) = \frac{116}{52}$

Simplify

$E(x) = 2.23$

Hence, the expected value of a round is $2.23

<h3>The expected value when the game is played 755 times</h3>

In (a), we have:

$E(x) = 2.23$

In probability, we have:

$E(nx) = n * E(x)$

So, we have:

$E(755x) = 755 * 2.23$

$E(755x) = 1683.65$

Hence, the expected value when the game is played 755 times is $1683.65

What’s five and one-half less than 3 times a number ?

notka56 [123]

The equation is 3n - 5 1/2. 5 1/2 = 5.5

3n - 5.5

n could equal 1 so, 3 x 1 - 5.5 = -2.5

3n - 5 1/2 = -2.5
