There are eight balls in an urn. They are identical except for color. Five are red, two are blue, and one is yellow. You are to draw a ball from the urn, note its color, and set it aside. Then you are to draw another ball from the urn and note its color. Let P(x, y) be the probability of choosing an x-colored ball on the first draw and a y-colored ball on the second draw. Compute the probability for each outcome of the experiment. (Enter your answers as fractions.)P(R, R) =P(R, B) =P(R, Y) =P(B, R) =P(B, B) =P(B, Y) =P(Y, R) =P(Y, B) =

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
