Answer:
The mean is 40.35 and the standard deviation is 0.13.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a certain type of olivine assembly, the silicon dioxide (SiO2) content (in weight percent) in a randomly chosen rock has mean 40.35 and standard deviation 0.4.
Sample of 10:
By the Central Limit Theorem, the mean is 40.35, and the standard deviation is 
The mean is 40.35 and the standard deviation is 0.13.
Answer:
29 seconds
Explanation
anchor dropped in to water at the rate = 2.5 m/s
so for one second = 2.5 m
so for 45 sec= 2.5 x 45 = 112.5 m
but it was already 40 m under water, so it have fallen from= 112.5-40= 72.5 m
so as we know the rate of falling was =2.5 m/s
so for 72.5 meter, it took = 72.5 /2.5= 29 sec
it took for anchor to get down to the water surface after it started dropping.
