Answer:

a standard crd deck has 52 cars so

the probability of getting red is 0.5 since 2 of the 4 faces are red. The probability for getting a king is 1/13 since there are 13 different card values.

Note:

52 cards in a deck

26 red cards in a deck

4 kings in a deck

Let’s set:

P(A) = drawing a red card
P(B) = drawing a king card

P(A or B) = drawing a red or a king card

P(A and B) drawing a red AND a king card

Formula:
P(A or B) = P(A) + P(B) - (A and B)

Solve:
P(A and B) = 26/52 • 4/52 = 1/26

P(A or B) = 26/52 + 4/52 - 1/26 = 7/13

Your answer is 7/13.

(I hope I’m correct)

The equation of a line is y= -1/2x - 2. What is the equation of the line that is perpendicular to the first line and passes thro

Fed [463]

If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
