Answer:
24
Step-by-step explanation:
The rounded numbers are ...
13 7/10 = 13.7 ⇒ 14
10 1/8 = 10.125 ⇒ 10
The sum of the rounded numbers is 14 +10 = 24.
The estimate of the sum is 24.
Total amount of tennis balls:
5 green tennis balls + 2 yellow tennis balls + 6 red tennis balls + 8 blue tennis balls = 21 tennis balls.
The problem says that Tony removes 4 tennis balls without replacement, so:
Let's call Event A= yellow, green, blue, green
P(A) = (2/21)(5/20)(8/19)(4/18)
P(A) = 2.23x10^-3
P(A) = 0.00223
P(A) = 0.223%
There is a formula for this, I attached an image
The final equation is (x-5)^2 + (y+4)^2 = 10^2.
Hopefully this'll help you!
