Answer:
<u>12 ways</u>
Step-by-step explanation:
The different ways to choose which three hamsters to put in the red cage.
At first , she must choose one of the two of the hamsters, Felix and Oscar, because they do not get along and cannot be in the same cage.
So, the number of ways to choose one of them = 2
Then she will choose 2 from the remaining 4 hamsters (order does not matter)
The number of ways to choose 2 from 4 = 4C2 = 6
So, the total number of ways = 2 * 6 = 12
Answer:
85 miles.
Step-by-step explanation:
Lets begin by figuring out the number of miles in 4 inches. Since every 2 inches make 40 miles, we can figure out that there are 80 miles in 4 inches. To figure out that .125 part, we multiply 40 by .125, to get 5. We can add 80 plus 5 to get our grand total of 85 miles.

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
