There are 26 red cards and 26 black cards in a standard deck.

So, the probability of selecting a red card is 1/2.

There are 2 black queen in a standard deck : the queen of spades and the queen of clubs.

So, the probability of selecting a black queen is 2/52, or 1/26.

There are 4 of the 4 cards in a standard deck : 4 of spades, 4 of clubs, 4 of diamonds and 4 of hearts.

And, there are 12 face cards : jack, queen, king, each has spades, clubs, diamonds and hearts.

So, the probability of selecting a 4 or a face card is 16/52, or 4/13.

The probability of them all happening at the same time is : 4/13 x 1/26 x 1/2 = 4/676, or 1/169.

Determine if the following lines are parallel (never intersect), perpendicular (intersect at a 90 degree angle), intersecting (i

mihalych1998 [28]

Answer:

These lines are perpendicular.

Step-by-step explanation:

Put both equations in the slope intercept form of a line.

y = -6x - 8 This is already in the slope intercept form for a line

-x + 6y = 12 Add x to both sides of the equation

6y = x + 12 Divide through the whole equation by 6

y = 1/6x +2

Now we compare the two slopes of -6 and 1/6. They are negative reciprocals of each other. That means that the line are perpendicular.
