Answer:
Confidence Interval in 95% confidence level for the quality rating is (6.06,7.46)
Step-by-step explanation:
Confidence Interval can be calculated using the formula M±ME where
- M is the mean of the sample
- ME is the margin of error in a given confidence level
Using the sample obtained from 50 business travelers we get
- Mean of the sample is 6.76
- standard deviation of the sample is 2.526
Margin of error (ME) around the mean using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- s is the standard deviation of the sample (2.526)
- N is the sample size (50)
Using the numbers in the formula we get:
ME=
≈ 0.70
Then the confidence interval becomes 6.76±0.70

Answer:
y = 1 · 5^x
Step-by-step explanation:
Use the given values in the given formula and solve for 'a' and 'b'.
y = a·b^x
5 = a·b^1 . . . . . . for (x, y) = (1, 5)
125 = a·b^3 . . . . for (x, y) = (3, 125)
Divide the second equation by the first:
125/5 = (a·b^3)/(a·b^1)
25 = b^2 . . . simplify
5 = b . . . . . . . take the square root
Substituting into the first equation, we can find 'a':
5 = a·5
1 = a . . . . . . . divide by 5
Written in the given form, the equation is ...
y = 1 · 5^x
Hello,
The answer should be "8=m".
Reason:
Since it takes 8 minutes to run 1 mile put that first:
8
Since how 8min equal 1 mile you put equal
8=
Since how it could be more miles but m
8=m

The Degree<span>
(for a polynomial with one variable, like </span>
x<span>
) is the largest exponent of that variable.Let's check each terms :
</span>

<span> has degree of 4 (x is an exponent of 1, y has 2, z is an exponent of 1. So 1+2+1 = 4).
</span>

has a degree of 5 (z has an exponent of 5).

has degree 6 ( y has 2 and z has 4. So 2+4=6).
<span>
Now that we have checked each terms, we know that
t</span><span>
he largest degree is 6, so the polynomial has a degree of 6.</span><span>
In short, your answer be 6.
Hope this helps !
