She needs 27 crates to make 7 steps. It makes more sense if you draw it out for yourself.

Answer:

2x + 2x+2 = 3x + 1

4x + 2 = 3x + 1

Subtract 3x from both sides

4x - 3x + 2 = 3x - 3x + 1

x + 2 = 1

Subtract 2 from both sides

x + 2 - 2 = 1 - 2

x = -1

Hope this helped!!!

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
