Answer:

  (3, 1)

Step-by-step explanation:

We assume you want the solution to the system ...

  • 2x−3y=3
  • x=y+2

The second equation gives a nice expression for x, so we can use that in the first equation.

  2(y+2) -3y = 3 . . . . substitute for x in the first equation

  2y +4 -3y = 3 . . . . . eliminate parentheses

  -y = -1 . . . . . . . . . . . collect terms, subtract 4

  y = 1 . . . . . . . . . . . . multiply by -1

  x = 1 +2 = 3 . . . . . . substitute for y in the second equation

The solution is (x, y) = (3, 1).

Compute the probability of event E if the odds in favor of E are (A) StartFraction 20 Over 27 EndFraction (B) StartFraction 25 O
vovikov84 [41]

Answer:

A) 0.4255

B) 0.5813

C) 0.5588

D) 0.7241

Step-by-step explanation:

Assuming that the probability for each case is the same, we can calculate the  probability by dividing the number of favourable cases with the total amount of cases. You can find the total amount of cases by adding the favourable ones with the non favourable ones, so, the probability of each case would be:

A) 20/(27+20) = 20/47 = 0.4255

B) 25/(18+25) =  25/43 = 0.5813

C) 19/(15+19) = 19/34 = 0.5588

D) 21((8+21) = 21/29 = 0.7241
