I'm taking this pre-test right now. I think the answer is "No, because sides JM and KL have different slopes from sides AD and BC."
After looking closely, it looks like JM and KL are slightly steeper lines than AD and BC.
Infinitely many ways!
Suppose you have the fraction 2/d.
<span>Pick </span>any<span> pair of integers a and b where b ≠ 0.</span>
Then 2b-ad is and integer, as is bd so that (2b - ad)/bd is a fraction.
Consider the fractions a/b and (2b - ad)/bd
<span>Their sum is </span>
a/b + (2b-ad)/bd = ad/bd + (2b-ad)/bd = 2b/bd = 2/d - as required.
<span>Since a and b were chosen arbitrarily, there are infinitely many possible answers to the question.</span>
Answer:
Step-by-step explanation:
Answer: -0.6
Step-by-step explanation:
Given : The number choices to a question : 5
Let we have no idea what the right answer is, so you pick one of the choices at random.
The probability that the answer is correct : 
Then , the probability of the answer is not correct : 
Then , the expected value of the number of points you get :-
Hence, the expected value of the number of points you get = -0.6
