Answer:
-1/3
Step-by-step explanation:
y = 3x+7
This is in the form y = mx+b
The slope is m so it is equal to 3
Perpendicular lines have slopes that are negative reciprocals
m perpendicular = - (1/3)
Answer:B

More card math! Easy!!
Exactly 1/4 of a 52-card deck of cards is clubs. Another 1/4 spades, another 1/4 is hearts, and the final 1/4 is diamonds. To find what one fourth of 52is, you can divide 52 by 4. That equals 13. So there are 13 clubs in the entire deck of cards. If you are trying <em>not </em>to get a club, you have to find the remainder of the cards without those 13. 52 - 13 = 39. This means that you have 39/52 odds of <em>not </em>getting a club. Simplified you get 3/4.
I did it the long way. A shorter was is to see that, obviously, one whole minus one fourth is three fourths.
[0,1] could not be used to represent a probability.
