Step-by-step explanation:
● A standard deck of cards has:
● 52 Cards in 13 values and 4 suits
● Suits are Spades, Clubs, Diamonds
and Hearts
● Each suit has 13 card values:
2-10, 3 “face cards” Jack, Queen, King (J, Q, K)
and and Ace (A)
Basic Card Probabilities
● If you draw a card at random, what is the
probability you get:
● A Spade? P(Spade)=13/52
● A Face card? P(Face Card)=12/52 (or simply 3/13)
● A Red Ace? P(Red Ace) = 2/52
Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
Im not sure tho sorry for your inconvenience
Answer:
Your slope is -1
Step-by-step explanation:
Find the change in x and the change in y and put it in change in y over change in x.
Δx = -1 - -2 = 1
Δy = -1 - 0 = -1
Slope = rise over run = Change in y over change in x = Δy/Δx = -1/1
Therefore the slope is -1/1 which is written as just -1
