Step-by-step explanation:
Look at the numbers from left to right as you compare them. This shows you which is greater.
Ex.) 1.85 and 4.33
Look at 1 and 4
4 is greater
The z-value that corresponds to a two-tailed 95% confidence interval is z = +/- 1.96. Then the bounds of the confidence interval can be determined as:
Lower bound = mean - z*SD/sqrt(n) = 20 - 1.96*2/sqrt(100) = 20 - 0.12 = 19.88 hours
Upper bound = mean + z*SD/sqrt(n) = 20 + 1.96*2/sqrt(100) = 20 + 0.12 = 20.12 hours
So the first choice is the correct answer: 19.88-20.12 hours
O = 2i - 1
o = output
2 i = twice the input
then -1 = one less
Answer:
<u>True:</u>
The solution is the product of two factors.
The second factor is itself the sum of three terms.
<u>False:</u>
The solution is the sum of two terms.
The coefficient is 3. (This one I'm confused about. There is no x/letter term, so there shouldn't be a coefficient in this problem at all.)
The second factor is the sum of two terms.
Answer:
5.4.
Step-by-step explanation:
If we divide 2 by 5 we get 0.4
So 5 and 2/5 = 5.4
