Probability of people liking comedy movies = 1/6
Hence,
If total number of people are 90, then the number of people liking comedy movies = 90/6 = 15
If total number of people are 180, then the number of people liking comedy movies = 180/6 = 30
If total number of people are 270, then the number of people liking comedy movies = 270/6 = 45
If total number of people are 360, then the number of people liking comedy movies = 360/6 = 60
Let the x-axis represent the total number of people and,
The y-axis represent the number of people liking comedy films.
The function will be :-
f(x) = x/6 , where x is the total number of people.
The graph is attached.
The answer is: 45 .
________________________________
3/5 * 75 = 3/5 * 75/1 ;
The "5" cancels to a "1"; and the "75" cancels to a "15" ;
since "75÷5 = 15" ; and since "5÷5 =1" .
So, rewrite the problem:
3/1 = 15/1 = 45/1 = 45.

Other method:
___________________________
3/5 * 75 = 6/10 * 75 = 0.6 * 75 = 45.0 = 45 .

We are to find the graph which best represents the given function:
f (x) = 5 (2)^-x
To be able to solve this, let us write the function of each graph mathematically
and select the correct one.
Graph A:
function f of x equals 5 multiplied by 2 to the power of negative x =>
f (x) = 5 (2)^-x
Graph B:
function f of x equals 5 multiplied by 2 to the power of x => f (x) = 5
(2)^x
Graph C:
function f of x equals 10 to the power of x => f (x) = 10^x
Graph D:
function f of x equals 10 to the power of negative x => f (x) = 10^-x
Therefore based on the mathematical interpretations above, only Graph A is
similar to the given function. Hence the correct answer is:
Graph A
Answer: 6.3
Step-by-step explanation:
The formula for geometric mean is given as :
G.m =
Therefore , the geometric mean between 4 and 10 will be :
G.m =
=
= 2
= 6.3
