Step-by-step explanation:
Answer: (1.64,4.01)
Step-by-step explanation:
The confidence interval for the population variance is given by :-
Given : n= 69 ;
Significance level :
Using Chi-square distribution table ,
[by using chi-square distribution table]
Now, the 95% confidence interval for the standard deviation of the height of students at UH is given by :-
Hence, the 99% confidence interval for the population variance of the weights of all axles in this factory is (1.64,4.01).
<span>If 43% of adults say cashews are their favorite kind of nut, then if you ask 12 adults the result should be: 12 adults x 43%= 5.16 adults.
If you round the result, you will get 5 of 12 adults saying that cashews are their favorite nut. Then the right option would be </span><span>(b) at least four</span>
One way to do this problem is to determine the common difference. If the 5th and 8th terms are -9 and -21, we can do this by subtracting -9 from -21:
-21-(-9) = -12. The 5th and 8th terms are not consecutive, so we have to think in terms of (8-5), or 3, times the common difference to get from -9 to -21.
Note that -12 divided by 3 is -4. Thus, the common difference is -4.
Check: -9 - 4 = -13; -13 - 4 = -17; -17 - 4 = -21 (which is correct).
We know that the 5th term is -9. To find the 4th term, work backwards: subtract (-4) from -9, which produces -9+4=-5.
The fourth term is -5. Subtracting -4 from this (which is the same as adding 4 to this -5) produces the third term; it is -1. Can you now find the 2nd and 1st terms using the same approach?
100 and 101
the two integers are n and n+1. this means that 2n+1=201. n=100 and n+1=101
