Left to Right<u> </u>

<u>Algebra I</u>

Coordinates (x, y)

<u>Algebra II</u>

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (2, 1)

Point (6, 7)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(6 - 2)^2 + (7 - 1)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{4^2 + 6^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 36}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$

You draw a card from a deck. If you get a red card, you win nothing. If you get a spade, you win $5. For any club, you win

strojnjashka [21]

Answer:

Standard deviation = 0.547

Step-by-step explanation:

Given the data

$5 for spade

$10 for any club

$20 for an ace club

Lets assume Probability of getting these cards to be

0.5, 0.20 and 0.30

Therefore, mean would be

Summation (PX) = 5×0.5 + 10×0.2 +20×0.3

Summation (PX)/n= 10.5/35 = 0.3

Standard deviation = √0.3

Standard deviation = 0.547
