There is no real shortcut in learning integration formulas. You should take time learning and understanding how the formulas are derived until you are familiar with the formulas and you can easily recall the formulas. Hope this answers the question.

<span>6=2+u then u = 6 - 2 = 4
(-16)=(-9)-w then w = 16 - 9 = 7
8=r+4 then r = 8 - 4 = 4
v+(-3)=(-10) then v = -10 + 3 = -7
9=j+7 then j = 9-7 = 2
(-14)=r-6 then r = -14 +6 = -8
(-2)-k=4 then k = -2 -4 = -6
(-10)=n-8 then n = -10 + 8 = -2
(-9)=s+(-4) then s = -9 + 4 = -5
(-4)-s=0 then s = -4</span>

In the game of​ roulette, a player can place a ​$9 bet on the number 11, and have a 1/38 probability of winning. If the metal ba
damaskus [11]

Answer:

1. What is the expected value of the game to the​ player?

Expected value= -$0.47368

2. If you played the game 1000​ times, how much would you expect to​ lose?

Expected value= -$473.68

Step-by-step explanation:

1. What is the expected value of the game to the​ player?

Expected value can tell how much you will gain/lose every time you do the game. To find the expected value you need to multiply every value with its chance to occur. There are two types of events here, winning and losing. You have 1/38 chance of winning $315 and 37/38 chance of losing $9.  

The expected value will be:

expected value= 1/38 * $315 + 37/38*(-$9) = $8.2894 - $8.7631

expected value= -$0.47368

You are expected to lose $0.47368 every time you play

2. If you played the game 1000​ times, how much would you expect to​ lose?

Expected value calculated for each roll. If you want to know how much you gain/lose by multiple rolls, you just need to multiply the expected value with the number of rolls. The game has negative expected value so you are expected to lose money instead of gaining money. The money you expected to lose will be:

number of roll * expected value

1000 timer * -$0.47368/time= -$473.68

You are expected to lose $473.68 if you play the game 1000 times.

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).
harina [27]

The equation of line is:

y=-\frac{1}{2}x+6

Further explanation:

Given

y = 2x + 2

Comparing it with standard form:

y=mx+b

Let m1 be the slope of given line

m_1=2

We know that product of slopes of two perpendicular lines is -1

Let m2 be the slope of second line

m_1.m_2=-1\\2*m_2= -1\\m_2 = -\frac{1}{2}

Putting the value of m2 in standard form

y=-\frac{1}{2}x+b

To find the value of b, putting (6,3) in equation

3=-\frac{1}{2}(6)+b\\3=-3+b\\3+3=b\\b=6

Putting the values of b and m, we get

y=-\frac{1}{2}x+6

The equation of line is:

y=-\frac{1}{2}x+6
