Harlamova29_29 [7]

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±\frac{t*s}{\sqrt{N}} 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±\frac{2.977*2}{\sqrt{15}} =12±1.537

Therefore, mean track length for this rock specimen is between 10.463 and 13.537

Trevor took one of his friends out to lunch. The lunches cost $248.40 and he paid 12.5% sales tax. If Trevor left a 15% tip on t
bixtya [17]
He paid ...

-- The cost of the lunches      (100%  =  1.00 of it)    

-- 15% of the cost as a tip    (15%  =  0.15 of it)

-- 12% of the cost as sales tax  (12%  =  0.12 of it)

Total that he paid = (1.00 + 0.15 + 0.12)  =  1.27 of $248.40

                                                           =      $315.47   .

Trevor is one generous guy !
