Answer:

$\frac{bd}{(a + c)} = \frac{3 \times ( - 4)}{ (- 2) + ( - 12)} = \frac{( - 12)}{( - 14)} = \frac{6}{7} \\$

<h3>6/7 is the right answer.</h3>

Find the value of x that makes this equation true, just write a number for your answer. Use / for writing fractions

Tcecarenko [31]

Answer:

1/15

Step-by-step explanation:

The first thing to do is to change both denominators so that they're the same. In this case, that would be 15.

Then, whatever you do to the denominator, you must also do to the numerator.

$\frac{9}{15}$ + x = $\frac{10}{15}$

X = 1/15

Answer:

Expected value of the game: -$0.421

Expected loss in 1000 games: $421

Step-by-step explanation:

There are two possible outcomes for the event:

- There is a 1 in 38 chance of winning $280

- There is a 37 in 38 chance of losing $8

The expected value for a single game is:

$E(X) = \frac{1}{38}*\$280-\frac{37}{38}*\$8\\E(X)=-\$0.421$

The expected value of the game is -$0.421

In 1,000 plays, the expected loss is:

$L = 1,000*-\$0.421\\L=-\$421$

You would expect to lose $421.

Write the equation of the line that passes through the points (2,−8) and (1,7). Put your answer in fully reduced point-slope for

ValentinkaMS [17]

Point-slope form of equation is: $y - 7 = -15(x-1)$

Step-by-step explanation:

Given points are:

(2,-8) and (1,7)

First of all we have to calculate the slope of the line

so,

$m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{7-(-8)}{1-2}\\=\frac{7+8}{-1}\\=\frac{15}{-1}\\= -15$

Point-slope form is given by:

$y-y_1 = m(x-x_1)$

Putting the value of slope

$y-y_1 = -15(x-x_1)$

We can put any one of two given points in the equation to find the final form of point-slope form

Putting (1,7) in the equation

$y - 7 = -15(x-1)$

Hence, point-slope form of equation is: $y - 7 = -15(x-1)$

Reducing and simplifying

$y - 7 = -15(x-1)\\y-7 = -15x+15\\y-7+7 =-15x+15-7\\y = -15x+8\\15x+y = 8$

Which expression gives the distance between the points (2,4) and (5,3)?

love history [14]

Answer: $\sqrt{10}$

Step-by-step explanation:

$d = \sqrt{(x_{2}-x_1)^2 + (y_{2}-y_1)^2 } \\x_2 = 5\\x_1 = 2\\y_2 = 3\\y_1 = 4\\\\\\d = \sqrt{(5-2)^2 + (3-4)^2 } \\\\d = \sqrt{3^2 + 1^2}\\d = \sqrt{10}$
