Answer:
m = 6,9
Step-by-step explanation:
We are given that
is a solution to given differential equation.
First we 3evaluate the value of:

Putting these value in the above differential equation, we get,





Thus, for m = 9,6 , the function
is a solution of given differential equation.
Step-by-step explanation:
How many pages can Rick write in 8 hours

Answer: 0.547
Step-by-step explanation:
As per given , we have
Population mean = 
Population standard deviation= 
Sample size : n= 36
We assume that number of apps used per month by smartphone owners is normally distributed.
Let
be the sample mean.
Formula : 
The probability that the sample mean is between 19.5 and 20.5 :-

[using standard normal distribution table for z]
Hence, the required probability = 0.547
