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

Answer:
Value of given expression is 6434.5532 and number of significant figures is 8.
Step-by-step explanation:
The given expression is
We need to find the value of given expression.
On simplifying the parentheses we get
On multiplication we get
Therefore, the value of given expression is 6434.5532 and number of significant figures is 8.
The correct simplification of 8x2(5x 2x2 − 3) is
- Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
- Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
- Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.
The correct simplification of 8x2(5x 2x2 − 3).
Rearranging the above expression in descending order of power, we get:
The correct simplification of 8x2(5x 2x2 − 3) is
