Y = m x + b

b = 2/5

0 = m * 3 + 2/5

-3 m = 2/5

m = - 2/5 : 3 = -2/15

The slope intercept form of the linear equation:

**y = -2/15 x + 2/5 **

The **expected value **of the game is the **mean value **of the game

The **expected value **of the game is $1

<h3>How to determine the expected value?</h3>

There are 13 spades in a deck of card of 52

So, the **probability **of **selecting **a spade is:

P(Spade) = 13/52

Simplify

P(Spade) = 1/4

Winning = $7

The **probability** of not **selecting **a spade is:

P(Not spade) = 1 - 1/4

Simplify

P(Not spade) = 3/4

Lose = $1

The expected value of the game is:

This gives

Simplify

Evaluate

Hence, the **expected value **of the game is $1

-98 is answer
If -98 is divided by 7
-98/7 = -14
We get -14
Which is 6 less than -8
As, -8 - 6 = -14

Simple,

120 divide it by 3 to get your length.

Thus, it covers 140 ft of the wall.

A regular hexagon has 6 equal sides and all the inner angles are the same. Since we know that a hexagon has 6 equal sides and we know one side is 6ft we can find the fence with out the side walk by multiplying 6 x 6 = 36ft of fence. The question at hand is how much fenceing would be needed if each side will be 2ft longer. This means we take the 6ft we know and add 2ft to the 6f, which would give us 8ft of fence for one side. Now we take 8ft and times it by the number of side a hexagon has, which is 6. So 8 * 6 = 48ft of fence
