Which statement below correctly depicts the expected value of a fair game?
E(X) = 0
E(X) = 1
E(X) > 0
E(X) >1

Answers

Answer 1

Answer:

e(x)=0 will be  your answer

Step-by-step explanation:

First of all it is important to know about the fair game.  A game is said to be fair if it has equal chances of winning for both the parties.

In Statistical terms, this can be said as expected value =0

If E(X) = 1 where X is from the player, then organizer of the game would have more chances of losing.

Similarly if E(X)>0where X is from the player, then organizer of the game would have more chances of losing.

Also if E(X)>1, where X is from the player, then organizer of the game would have more chances of losing.

Hence a fair game is one where

Which piece of information below will not help you prove that triangles ABC and DEF are congruent using ASA?

Answers

Answer:

A) [tex]AC=DF[/tex]

Step-by-step explanation:

Given

See attachment for triangles ABC and DEF

Options

A) [tex]AC=DF[/tex]

B) [tex]AB=DE[/tex]

C) [tex]\angle B=\angle E[/tex]

D) [tex]\angle A=\angle D[/tex]

Required

Which does not prove the congruence of ABC and DEF using ASA?

From the attachment, we have the following:

[tex]\angle A = \angle D[/tex] --- Angle

[tex]AB = DE[/tex] --- Side

[tex]\angle B = \angle E[/tex] ---- Angle

The ASA theorem means that 1 side of both triangles are equal.

By comparing the listed parameter to the options, we can see that options B, C and D prove that both triangles are congruent by ASA.

However, option A [tex]AC=DF[/tex] cannot be used because that will mean that two sides of both triangles are equal. This does not support the ASA theorem

Find two points and slope !

Answers

Answer:

slope = 1

two points: (0,-6) and (6,0)

Step-by-step explanation:

Figuring out the slope:

Since we have the two points, we would need to use the slope formula of:

(y2-y1)/(x2-x1)

So it would be (-6 - 0) divided by (0 - 6) = -6/-6 = 1

slope is 1

Answer:

1 - Copy and complete this table for y = 2x

x = -3 | y = -6

x = -2 | y = -4

x = -1 | y = -2

x = 0 | y = 0

x = 1 | y = 2

x = 2 | y = 4

x = 3 | y = 6

2 - Copy and complete this table for y = 2x - 3

x = -2 | y = -7

x = -1 | y = -5

x = 0 | y = -3

x = 1 | y = -1

x = 2 | y = 1

x = 3 | y = 3

x = 4 | y = 5

x = 5 | y = 7

y=2x

The way to solve this is plugging in your above x value in for x into the equation y=2x and solving for y.

Example:

y=2x

^You want to find x=-3

y= 2(-3)

y= -6

how do you simplify 1 1/8 x 3 2/3 someone please help me!

Answers

Answer:

4 1/8

Step-by-step explanation:

1 1/8 x 3 2/3 = ?

9/8 x 11/3 = 99/24

99/24 = 4 1/8

Answer:

1. find the least common denominator for the left-hand side fraction. This brings you to 8/8x + 3x/8x = 1/2

2. Add the numerator on the left-hand side of this equation, (8+3x)/8x = 1/2

3. Multiply both sides by 2, that will lead you to (8+3x)/4x =1/1

4. Multiply both sides by 4x, we get 8+3x=4x

5. Finally, subtracting 3x from both sides simplifies the equation to x=8. Note that this is as simple as this expression can get so you can not go any further, therefore 1/x+3/8=1/2 simplifies to x=8.
