Answer:
standard deck has 52 cards. probability of king is 4/52 and probability of a queen is 4/52, so 4/52 + 4/52 = 8/52=2/13
Step-by-step explanation:
Answer:
y = - 
x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (4, - 3)
m = 
= 
= - , thus
y = - x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (- 2, 0 ), then
0 = 1 + b ⇒ b = 0 - 1 = - 1
y = - x - 1 ← in slope- intercept form
The answer is D
because any number to the right will be greater than the left
Answer:
A.
exponential
Step-by-step explanation:
Exponential is best suited here because life span gradually increases from b to a over the years continuously. Whenever there is a continuous steady increase, exponential function is more suitable.
Logrithamic function will not suit because rate of change of log is 1/x and if x population is very large this will be almost equal to 0 which is not correct.
But exponential say a^x rate of increase= a^x log a and when a is small this will represent a slow steady state of increase.
Step function will not suit as step functions are discontinuous at every integral value, but the population function is a continuous function.
Absolute value function is suitable only for functions symmetrical about a particular value of x or y
But here there is no symmetry but steady increase. Hence exponential is the best suitable graph.
