Component of V
From the question, we understand that V is in standard position.
This implies that V starts at the origin (0,0) and ends at (a,b)
So, vector V is:
This gives:
Answer:
The function that best models the given data is;
B. h(t) = -6.73·t² + 14.19·t + 0.83
Step-by-step explanation:
The data in the given table is presented as follows
Where;
Time, t(s) is the independent variable
Height, h(m) is the dependent variable
Therefore, we have;
When t = 0, h = 1.0
From the given functions, we have the following table of the result of the function generated with Microsoft Excel
By comparison, the function that nest models the given data is the function 'B', given as follows;
h(t) = -6.73·t² + 14.19·t + 0.83.
Answer:
The question is incomplete, but the step-by-step procedures are given to solve the question.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 2.575.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M.
The upper end of the interval is the sample mean added to M.
The 99% confidence interval for the population mean amount of beverage in 16-ounce beverage cans is (lower end, upper end).
