The line below are parallel. If the green line has a slope of -1/2, what is the slope of the red line?
2 answers:
Answer: B.
Step-by-step explanation:
In the given picture, we have two lines area parallel, one is red and other is green.
We know that the slopes of parallel lines are equal.
Therefore, if the green line has a slope of then ,the slope of red line will also be
because they are parallel.
Hence, B is the correct option.

Answer:
The probability that the first card is a Heart and the second card is a Spade is 0.064.
Step-by-step explanation:
A standard deck of 52 cards is shuffled and two cards are drawn without replacement.
The denominations of the cards are as follows:
Spades (S) = 13
Hearts (H) = 13
Diamonds (D) = 13
Clubs (C) = 13
Compute the probability of selecting a Heart first as follows:
Compute the probability of selecting a Spade second as follows:
Since the two cards are selected without replacement the second draw is independent of the other.
Then the probability that the first card is a Heart and the second card is a Spade is:
Thus, the probability that the first card is a Heart and the second card is a Spade is 0.064.
