white balloons. It costs $3 to play the game. The player wins $0.50 for white, $2 for green, and $15 for red. What is the expected value you should earn per game?

If this is probability then the answer should be $.50 bacause you throw the dart until you hit 1 balloon there is 100 white balloons so there is a .75% chance to hit white, a .02% chance to hit red and a .22% chance to hit green. the most likely one to hit is white. so you would earn
$.50 per game

Answer:

y = -40

Step-by-step explanation:

|y/5+8| - 3 = -3

|y/5+8| = -3 + 3 = 0

y/5+8 = 0 or -0 but 0 and -0 are the same so there would be only 1 answer for this:

Subtract both side by 8

y/5 = -8

Times 5, we got:

y = -40

Hope this help you :3

bija089 [108]

9514 1404 393

Answer:

  3x +5y = -30

Step-by-step explanation:

The parallel line can have the same x- and y-coefficients. You can find the value of the new constant by using the given point for x and y:

  3x +5y = 3(-5) +5(-3) = -30

  3x +5y = -30

Solve this equation for y. <br> 3x - 5y = 12
Volgvan
-5y=12-3x (subtract 3x from both sides)
y = - 12-3x/5 (divide both sides by -5)
y = - 3(4-x)/5 (common term is 3)

Write an equation of the line that is perpendicular to the line y = 1 2 x + 8 that passes through the point (4,6)
Katen [24]

Answer:

\large\boxed{y=-2x+14}

Step-by-step explanation:

\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\============================\\\\\text{We have}\ y=\dfrac{1}{2}x+8\to m_1=\dfrac{1}{2}.\\\\\text{Therefore}\ m_2=-\dfrac{1}{\frac{1}{2}}=-2.\\\\\text{The equation of the searched line:}\ y=-2x+b.\\\\\text{The line passes through }(4,\ 6).

\text{Put thecoordinates of the point to the equation.}\ x=4,\ y=6:

6=-2(4)+b\\\\6=-8+b\qquad\text{add 8 to both sides}\\\\b=14
