What is the distance between point A and point B?what is the ordered pair for each of the points plotted above?
Alekssandra [29.7K]

Answer:

A: (0,0), B: (3, -4), 5 units

Step-by-step explanation:

A: (0,0), B: (3, -4)

To find the distance, use the distance formula. Square-root((0-3)^2+(0-(-4))^2) ---> Square-root((-3)^2 + 4^2) ---> Square-root(9+16) ---> Square-root(25) ---> 5units.

Uh can someone please help? please get it right and try to explain how
Anestetic [448]

Answer:

From least likely to most likely:

Colorado Bronze wins

I Am Pat wins

Good Legs Lance wins

Step-by-step explanation:

Converting all probabilities to the same type may be easier to visualize and see the chances. Let's convert each chance to percentage:

P(I Am Pat wins) = 3/10 = <u>30%</u>

P(Good Legs Lance wins) = 0.6 = <u>60%</u>

P(Colorado Bronze wins) = 10%= <u>10%</u>

Thus, the desired order is:

Colorado Bronze wins

I Am Pat wins

Good Legs Lance wins
