Answer:

Well to start we use the distance formula

Step-by-step explanation:

The distance formula is $\sqrt{(x_{2} -x_{1})^{2}+ (y_{2} -y_{1})^{2 }$

It's very simple you just plug in the coordinates.

The first coordinates is the x1 and y1 and the second coordinates is x2 and y2.

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

Dan had forty-three dimes and forty-one nickels in his bank. His dad borrowed nineteen nickels from Dan.

41-19 is 22 so he has 22 nickels. The amount of dimes is put in there to distract you. Just ignore those! :)
