Answer:
Look at picture attached
Step-by-step explanation:
I have created the graph on DESMOS. I recommend you use that website as it helps a lot with visualizing graphs :)
Edit: The second attachment shows the point you can plot.
Rather than solve the entire problem for you, I'll give you some hints to help you get started:
1. The amplitude of your sinusoidal graph is |3|, or just 3.
2. Because of that, your graph begins at the point (0,3).
3. Because this is the cosine function, your graph descends from (0,3) to y=3 and then begins to ascend (back to y=3).
4. The coefficient of x is "one half pi," or pi/2. Call this "b".
5. The period of your function is 2pi/b. Here, b=pi/2.
Dividing, [2pi]/[pi/2] = 4.
6. Mark your horizontal axis as follows: x=0, 4, 8, 12, 16, ...
7 Draw one cycle of the cosine function with amplitude 3. It must begin at (0,3) and end at (4,3) (which covers one period).
8. Draw another cycle or two, beginning at (4,3) and ending at (8,3), and so on.
Answer:
• (a)1320.5 thousand per year
,
• (b)f(x)=1320.5x+10602
,
• (c)f(7)=19846 thousand
Explanation:
Sales in the year 2009 = 10,602 thousand
Sales in the year 2013 = 15,884 thousand.
(a)Average rate of change (slope) from 2009 to 2013.
(b)If x is the number of years since 2009 and f(x) is the number of vehicles sold
When x=0, f(x)=10,602 thousand
The slope-intercept form of the equation of a line is: y=mx+b
The equation of the line through these two points is:
(c)Number of vehicles sold in 2016.
2016-2009=7
Therefore, when x=7
The number of vehicles sold, f(x) will be:
The value of minimum usual value is,
The value of maximum usual value is,
Given the values of the parameters of Binomial Distribution are,
Total number of trials (n) = 1490
probability of success in one trial is (p) = 2/5
The probability of failure in on trial is given by,
For Binomial distribution we know that,
Mean
and Standard Deviation
Now, calculating the required measurement we get,
The minimum usual value is given by,
Mean -2 Standard Deviation
The maximum usual value is given by,
Mean + 2 Standard Deviation
Hence the minimum and maximum usual values are -119.2 and 1311.2 respectively.
