Mathematics

Answer:

3/(n + 3)

Step-by-step explanation:

The given probability that Sara wins a raffle draw, P = n/(n + 3)

Given that the sum of all probabilities is 1, we get

The probability that Sara does not win, Q = 1 - P

Therefore;

Q = 1 - n/(n + 3) = (n + 3) - n/((n + 3) = 3/(n + 3)

The probability that Sara does not win, Q = 3/(n + 3)

Function A is represented by the equation y = 6x - 1.
Nezavi [6.7K]

Answer:

The function graphed is f(x) = 3x + 1

See that the y=intercept is at (0,1). That's where the +1 comes from.  

Note that the graph goes up 3 spaces every time it goes 1 to the right.  3/1 = 3 is the slope.

The answer to 12 is C.

The answer to 13 is B.  Neither is a function.  For a function of x to exist, for every x, there must be only one y.  In both tables, there's a number for x that gives two different y's.
