Answer:
Her average is 75
Step-by-step explanation:
To be able to find the average of a group of numbers you must add them all then divide them by how many numbers that there are.
Step 1: Add all the values
Step 2: Divide
Step 3: Check your work
Step 4: Celebrate
You got the correct answer, now be proud of yourself.
The correct answer is D.
As you can see, the exponential function grows by doubling the previous output with each increment of the input: start with 1, you double it to get 2, then you double it to get 4, 8 and so on.
On the other hand, the linear function adds 7 with each step. This means that the exponential function will eventually reach and pass the linear one, and will definitely be grater from that point on. In fact, if we continue the table, we get
and you can see how the exponential growth is much faster than the linear one.
