Step-by-step explanation:
all work is pictured and shown
X=11 because it looks as if the x is half of the y
The data set is roughly periodic, you can see the data that follows a pattern. For example, data point 1 is (1, 102), the 5 is (5, 98) and 9 is (9, 100).
Every 4 periods, the values resemble each other.
The same can be shown with the point (2, 76) and the point (6, 74) and (10, 75).
Therefore, it can be concluded that the period is 4 and the amplitude approximately 25.
Finally, the correct option is the third.
Period 4 and approximate amplitude of 25
Answer:
200(1.10) to the 20 power.=$1345.499 rounded to nearest 10th is $1345.4
Step-by-step explanation: you start with $200 times 1.10 which represents one 10%. you will then set up the formula to the 20th power to shorten your steps which represents the 20 weeks the 10 % would be added. and your answer would be $1345.4 if you rounded it to the nearest 10th.
