It could be a parallelogram because they too, have 2 sides that have one value and another two sides with a different value. a rhombus would work too.
Answer:
17.85
Step-by-step explanation:
it would be $5.95 per tree times that by 5 you get $17.85
The answer is the last choice 2 1/2
20 000 * 0.08(8%)= 1600
1600 * 20(years) = 32 000
Therefore you would have $32 000 after 20 years
It is given the probability that a dancer like ballet is 0.35
So, P(B) = 0.35
It is given the probability that a dancer like tap is 0.45
So, P(T)= 0.45
The probability that he likes both ballet and tap is 0.30
So, 
the probability that the dancer likes ballet if we know she likes tap. This is the case of conditional probability.
So, 

= 0.666
= 0.67
Therefore, the probability that the dancer likes ballet if we know she likes tap is 0.67.
Option 3 is the correct answer.
