Teri and Lee are playing a game that consists of consists of spinning a spinner with eight equal spaces numbered 1 through 8, and then flipping two coins at the same time.
Terri wins 10 points if the spin is greater than 5 and the coins are different (one head and one tail).
Lee wins 15 points if the spin is an even number and the coins are both tails.
Is the game is fair or unfair? Why?

A.The game is not fair, because Terri’s expected value is 10(4/8)(2/4)=2.5 and Lee’s expected value is 15(4/8)(1/4)=1.875.
B.The game is fair, because Terri’s expected value is 10(3/8)(2/4)=1.875 and Lee’s expected value is 15(4/8)(1/4)=1.875.
C.The game is not fair, because Terri’s expected value is 10(38)(13)=1.25 and Lee’s expected value is 15(4/8)(1/3)=2.5.

c + 301 = 270

Step-by-step explanation:

c = -31

Answer:

AC=22

Step-by-step explanation:

The measure of the Length of AC is; 35

We are given;

ac = 5x

ab = 12

bc = 3x + 2

ab + bc = ac

Thus;

12 + 3x + 2 = 5x

14 + 3x = 5x

Subtract 3x from both sides to get;

5x - 3x = 14

2x = 14

x = 14/2

x = 7

ac = 35

Answer:

y = 5/2x - 5

Step-by-step explanation:

Step 1: Write equation

5x - 2y = 10

Step 2: Solve for x

Answer:

y = (5/2)x - 5

Step-by-step explanation:

5x-2y = 10

Subtract 5x from both sides

-2y = 10 - 5x

Rearrange

-2y = -5x + 10

divide both sides by -2 to isolate y

y = (5x/2) + (10/-2)

y = (5/2)x - 5

=====================================================

Explanation:

The given angle is ∅ = 300. This x value is between 270 and 360, so we're in quadrant IV (the southeast quadrant)

The rule to get the reference angle y for this quadrant is

Ф = 360-∅

This tells us the angle made with the positive x axis

Ф = 360-∅

Ф = 360-300

Ф = 60

A 60 degree angle forms with the positive x axis as shown in the diagram below.

Answer:

60n-30

Step-by-step explanation:

you would do 15 * 4n

that would give you 60. since 15 *4 is 60 and then you would just put the n

15*2 equals 30. You would make it a negative 30 since it is a negative 2.

then you would combine them and get the answer

60n-30

Answer:

  9/5

Step-by-step explanation:

The slope between the two points can be found by ...

  m = (y2 -y1)/(x2 -x1)

  m = (-16-2)/(-10-0) = -18/-10

  m = 9/5

The slope of the line is 9/5. Perhaps this is a match to choice A.

Answer: 9/5

m = (y2 -y1)/(x2 -x1)

 m = (-16-2)/(-10-0) = -18/-10

 m = 9/5

16 inches by 32 inches or 1 1/3 feet by 2 2/3 feet

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

x is the cost of the drawing tablet

x+ 3.95 = 6.94  correct

The second equation add the total cost plus the cost of the drawing tablet  and sets it equal to the cost of the pencils.  This is not correct

6.94+x = 3.95   incorrect

Answer:

1. x=38.25

2. -7.8

3. the second option

Step-by-step explanation:

1. x+7.05=45.3

(move the constant to the right)

x=45.3-7.05

(calculate)

x= 38.25

(answer)

2.

(you subtract -4.3 by 3.5)

3.

(you can't use $6.94 + x = $3.95 because $6.94 is your total overall so you can only use that as your end result)
