Answer:
The 85% confidence interval for the mean is between 5.5 and 5.7 fast food meals consumed per week.
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 .
So it is z with a pvalue of , so
Now, find 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. So it is 5.6 - 0.08 = 5.52 = 5.5.
The upper end of the interval is the sample mean added to M. So it is 5.6 + 0.08 = 5.7.
The 85% confidence interval for the mean is between 5.5 and 5.7 fast food meals consumed per week.
For f (x):
The domain of the function is given by the values of x that satisfy the following inequality:
x> 2
Equivalently:
(2, inf)
For g (x):
g (x) = sqrt (2x-4)
The domain of the function is:
2x - 4> = 0
Clearing x we have:
2x> = 4
x> = 4/2
x> = 2
Equivalently:
[2, inf)
Answer:
The domain of the functions is not the same because the function g (x) includes the value of x = 2 in its domain.
The graph of f (x) does not include the value of x = 2 in its domain.
Answer:
<h2>a) 120 ways</h2><h2>b) 6 unique ways</h2>
Step-by-step explanation:
The question will be solved using the permutation formula since are arranging. <u>Permutation deals with arrangement.</u>
If there we are to arrange n objects taking 'r' at a time, this can be done in nPr ways.
a) If you therefore have 6 reindeer, Prancer, Rudy, Balthazar, Quentin, Jebediah, and Lancer, and you want to have 3 fly your sleigh. Since they are in a single file line, This can be done in 6P3 number of ways.
b) The number of unique ways to arrange the letters in the word DEN is 3! ways since there are only 3 letters in the word.
3! = 3*2*1
3! = 6ways
2000 is the correct answer hope this helps! :D
