Answer:
Step-by-step explanation:
We have been given that the area (in square meters) of a circular algae colony with radius r meters is given by
. The radius
(in meters) after t minutes is given by
. We are asked to write the formula for the area
(in square meters) of the algae colony after t minutes.
This problem is based on composite functions, in which function represents radius of circle after t minutes.
To write the formula for the area (in square meters) of the algae colony after t minutes, we need to substitute
in area formula
.
Therefore, our required formula would be .
Using the uniform distribution, it is found that:
A,B) 0.3 of the time does it take longer than 27 minutes for Josh’s bag to arrive in baggage claim.
C) 20% of the time does Josh’s bag arrive in less than 22 minutes.
--------------------------
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
--------------------------
- In the graph, we have that the distribution is uniform between 20 and 30 minutes, thus
--------------------------
Itens a and b:
- Above 27 minutes, thus:
0.3 of the time does it take longer than 27 minutes for Josh’s bag to arrive in baggage claim.
--------------------------
Item c:
- Less than 22 minutes, thus:
0.2*100 = 20%
20% of the time does Josh’s bag arrive in less than 22 minutes.

Answer: 0.6767
Step-by-step explanation:
Given : Mean = errors per page
Let X be the number of errors in a particular page.
The formula to calculate the Poisson distribution is given by :_
Now, the probability that a randomly selected page does not need to be retyped is given by :-
Hence, the required probability :- 0.6767
