Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for difference between two means is:
Given:
Confidence level = 80%
*Use a <em>t</em>-table for the critical value.
Compute the 80% confidence interval for difference between two means as follows:
Thus, the 80% confidence interval for difference between two means is (0.85, 1.55).

Answer: So if you want to find the total cost (c) for a certain number of months (m) and it costs $35 per month, you just need to multiply the number of months by the cost per month. So
35m=c
If you want to see the units cancel
($35/month)(months)=$
The months will cancel out, and you will be left with total dollars.
Not sure about the second part of your question, but if you wanted to figure out how much it would cost to be a member for 6 months, you would just plug in 6 for m.
35(6)=c
c=210
So $210
Step-by-step explanation:
The speed of a bus that travels 250 km in 2 hours is 145 because you have to divide 250 km and 2 hours which gives 145.
