Suppose someone gives you 6 to 1 odds that you cannot roll two even numbers with the roll of two fair dice. This means you win 6 dollars if you succeed and lose 1 dollar if you fail. What is the expected value of this game to you. What can you expect if you play 200 times

Answers

Answer:

0.75 ;

150

Step-by-step explanation:

Probability of rolling two even numbers :

{1, 2, 3, 4, 5, 6}

P(even) = 3 / 6 = 1/2

From a roll of 2 dice :

P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25

P(not even) = 1 - 1/4 = 3/4

X : ____ 6 _______ - 1

P(x) ____ 0.25 ____ 0.75

Expected value :

Σx*p(x) = (6*0.25) + (-1 * 0.75)

= 1.50 - 0.75

= 0.75

If 200 games are played :, n = 200

Expected value * n

0.75 * 200

= 150

now plug -3 into y=mx+b

y=-3(x)+b

choose any point and plug it into the equation, I am using (3,1)

Raymond's bake shop sold 26 1/2 cupcakes on Saturday on Friday the bake shop sold 19 3/4 dozen cupcakes what is the approximate percent increase in cupcake sales from Friday to Saturday

Answers

Answer: 34.18%  

Step-by-step explanation:

Given: On Saturday, Number of cupcakes sold = [tex]26\dfrac12[/tex] dozens

= [tex]\dfrac{53}{2}[/tex] dozens

[tex]=\dfrac{53}{2}\times12[/tex]    [  1 dozen = 12 items]

[tex]=53\times6\\\\=318[/tex]

On Friday, Number of cupcakes sold = [tex]19\dfrac34[/tex] dozens

= [tex]\dfrac{79}{4}[/tex] dozens

[tex]=\dfrac{79}{4}\times12[/tex]    [  1 dozen = 12 items]

[tex]=79\times3\\\\=237[/tex]

Increase in cupcakes = 318-237=81

Percent increase in cupcakes sales from Friday to Saturday = [tex]\dfrac{81}{237}\times100[/tex]

= 34.18%   (approx)

The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%

When x=3, y=9

When at the function at x=4, it is the largest so y=46

if zaeirr has 10 dogs and lamarr has 2 dogs how many more dogs does zaeirr have than lamarr?

Answers

Answer: 8

Step-by-step explanation:

For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.

10 subtracted by 2 is equal to the number 8.

The answer to our question is 8.

10-2 = 8

So Zaeirr has 8 more dogs

What is the solution to the system of equations below?
2x + 5y = 32

Answers

Answer:

x = 16 -5/2y

Step-by-step explanation:

2x + 5y = 32

2x = 32 -5y

/2 /2

x = 16 -5/2y

Answer:

y= 2x/5 + 6.4

Step-by-step explanation:

divide both sides by 2x

5y = 2x + 32

divide both sides by 5

y = 2x/5 + 6.4

follow same step to solve for x except first divide by 5y instead of 2x

Find the value of X express each answer as a decimal rounded to the nearest tenth.

Answers

Answer:

x = 15.6

Step-by-step explanation:

use the pythagorean theorem:

a² + b² = c²

a = 9

b = x

c = 18

(9)² + x² = (18)²

81 + x² = 324                    subtract 81 from both sides

x² = 243                            take the square root of both sides

x = √243

x = 15.6
