Answer:
y= -1/4
y= -0.25
Step-by-step explanation:
5/6y+1= -1/2y+1/4
<em>Subtract 1 from both sides</em>
5/6y= -1/2y-3/4
<em>Add 1/2y to both sides</em>
1 1/3y= -3/4
<em>Divide both sides by 1/3</em>
y= -1/4
y= -0.25
Answer:
1 - 1/10
Step-by-step explanation:
As strange as it may seem, the easiest way to answer this question is to calculate the probability of selecting an elephant first and then to subtract this probability from 1:
Adding up the Numbers of animals, we get 12+4+3+11, or 30. The probability of selecting an elephant is thus 3/30, or 1/10.
Thus, the probability of NOT selecting an elephant is 1 - 1/10 (Answer A).
