Afootball team has 5 freshman, 8 sophmores, 11 juniors, and 16 seniors. if two are chosen at random to participate in the coin toss, what the probability that both players chosen will be seniors

probability is

Step-by-step explanation:

A football team has 5 freshman, 8 sophmores, 11 juniors and 16 seniors.

total players = 5 + 8 + 11 + 16 = 40 players.

The probability that first player chosen to participate in the coin toss  will be seniors ( ) =

The probability that second player chosen will be seniors ( ) =

P = ×

P =

The probability that both players chosen will be seniors is

i would go with the first one

step-by-step explanation:

hope this

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
