Answer:
Step-by-step explanation:
Since the amplitude of the cosine function is 2, I would put the multiply it by 2. There is no phase shift
The period is 1/2, so it would be 4pi
Plug them in into y=Acos(Bx), y=2cos(4pix)
Can someone help me with my homework I really don’t get it:(

Answer:
69
70.5
84
Step-by-step explanation:
Firstly, we need to sort this list of numbers in order to perform calculations on it.
To find the mean we must add up and divide by the amount of numbers there are.
To find the median we must find the number in the middle of the set.
As there are two numbers in the middle positions, 69 and 72.
We must take the average of these two numbers to determine the middle.
The most is the most common number, which is 84.
