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

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (9, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(9+2)^2+(3-3)^2}$
Add/Subtract: $d = \sqrt{(11)^2+(0)^2}$
Simplify: $d = \sqrt{(11)^2}$
Simplify: $d = 11$

A card is drawn from a well-shuffled deck of 52 cards. find the probability that the card is a red card or a 10.

harina [27]

Total number of cards = 52

Find total number of red card or a 10:

Total number of cards that are red = 26

Total number of cards that are 10 but not red = 2

Total number of cards that are red card or 10 = 26 + 2 = 28

P(red card or a 10) = 28/52 = 7/13

So, 3/4 + 1 2/3 + 3 1/2 =

3/4 + 2/3 + 1/2 = 1 11/12

1 + 3 = 4

4 + 1 11/12 = 5 11/12
