Answer:
A. y = 3 cos (1/2) x.
Step-by-step explanation:
The y-intercept is 3 so it will contain 3 cos x (because y = cos x passes through (0, 1).
The graph of 3 cos x has been stretched horizontally by a factor 2 ( 3 cos x would pass through (π/2, 0) whereas the given graph passes through (π, 0).
So the equation is 3 cos(1/2) x
Answer:
7
Step-by-step explanation: it intersects on the y-axis

Definitions/How to Find It</u></h2>
Mean - The average of all of the numbers. Add up all of the numbers then divide it by the total number of numbers.
Median - The middle number of them all. Put the numbers in order from least to greatest and find the one in the middle.
Mode - The number that appears the most.
Range - The difference between the highest and lowest numbers Subtract the lowest number from the highest number.

Mean = 56.6
Median = 53
Mode = 41, 43, 63
Range = 56
