Answer:
-0.125
Step-by-step explanation:
The answer to this question would be yes
composite function J[P(W)=J(1/3w+4) represent paintings Jeremy completes in a year .
this equation means number of paintings= weeks(rate)
The function P takes a number of weeks as an argument and returns the number of paintings.
The function J takes some argument (unspecified) and returns a number of weeks per year.
The composite function that will give the number of paintings per year will be P(weeks per year) = P(J(y)).
P(J(y)) = 1/3·J(y) +4 .
Looking at the units of the input and output of each of the functions is called "units analysis."

Answer:
And using the cumulative distribution function we got:
The probability that preparation is within 2 minutes of the mean time is 0.134
Step-by-step explanation:
For this case we define the following random variable X= (minutes) for a lab assistant to prepare the equipment for a certain experiment , and the distribution for X is given by:
The cumulative distribution function is given by:
The expected value is given by:
And we want to find the following probability:
And we can find this probability on this way:
And using the cumulative distribution function we got:
The probability that preparation is within 2 minutes of the mean time is 0.134
