Answer: Not unusual.
Step-by-step explanation:
We know that the z-scores lower than -1.96 or higher than 1.96 are considered as unusual.
Given : Sample size : n= 65
Sample mean = 
Standard deviation : 
Formula for z-score : 
At x= 213
Since , -1.96< 0.17 <1.96
It means the probability of a sample mean being greater than 213 is not unusual.

Answer:
<h3>48 feet</h3>
Step-by-step explanation:
First we need to get the total minutes used by the submarine from 10:57 A.M to 11:03 A.M. The total minutes used within the specified period of time is 6 minutes.
If its depth then changed at a rate of 8 feet per minute, the submarine depth after 6 minutes will be expressed as shown;
8 feet = 1minute
x feet = 6 minutes
cross multiply;
x * 1 = 8 * 6
x = 48 feet
Hence the submarine depth at 11.03AM is 48 feet
9/27 is equivalent to 2/27
