Answer:

1

Step-by-step explanation:

A coin only has two outcomes. Meaning that she has a 50/50 chance of landing on each side. So, 50% of 20 is 10. According to the theoretical  probabilty, the coin would have landed on heads 10 times and tails 10 times. So, for that to be true Maria would have had to land on tails one more time.

What is the inverse of the function f(x) = 2x + 1? h(x) = 1/2x - 1/2
sweet-ann [11.9K]

Answer:

h(x) = x/2 - 1/2

Step-by-step explanation:

Here's the procedure for finding the inverse function algebraically:

1.  Replace the label 'f(x)' with the label 'y:'  y = 2x + 1

2. Interchange x and y:  x = 2y + 1

3.  Solve the resulting equation for y:  2y = x - 1, or y = (1/2)(x - 1) or y = x/2 - 1/2

This result corresponds to the 1st given possible answer choice.

The desired inverse function is h(x) = x/2 - 1/2
