Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.
Well, I would first make a table and then I would find the slope. That is my advice.
Answer:
Mean track length for this rock specimen is between 10.463 and 13.537
Step-by-step explanation:
99% confidence interval for the mean track length for rock specimen can be calculated using the formula:
M±
where
- M is the average track length (12 μm) in the report
- t is the two tailed t-score in 99% confidence interval (2.977)
- s is the standard deviation of track lengths in the report (2 μm)
- N is the total number of tracks (15)
putting these numbers in the formula, we get confidence interval in 99% confidence as:
12±
=12±1.537
Therefore, mean track length for this rock specimen is between 10.463 and 13.537
