Answer:

-104/41

Step-by-step explanation:

f(8) = -13

g(8) = 41/8

f/g(8) = -13/1 / 41/8 = -(13×8) / (41×1) = -104 / 41

f/g(x) = (3-2x) / (1/x + 5) = (3-2x)/1 / ((1+5x)/x) =

= x×(3-2x) / (1+5x) = (3x - 2x²) / (1 + 5x)

for x=8 this gives the same result.

A baseball team is in second place with the wind to loss ratio of .535. what percent of the games played did the team win?

Vsevolod [243]

Answer:

34.85%

Step-by-step explanation:

Let w be the probability of winning, then probability of losing would be (1 - w)

We know the ratio of winning to losing is 0.535

w/(1 - w) = 0.535

w = 0.535 - 0.535w

1.535w = 0.535

w = 0.348534202

% of games won:

0.348534202 × 100

34.8534202%
