We know that that the number of tickets bought by a person for a movie, follows a distribution with the mean µ = 3.7 and standard deviation σ = 1.5. Suppose that few hours before the start of the movie, there are 100 people waiting to buy tickets. If only 350 tickets remain, what is the probability that all 100 people will be able to buy the tickets they want? (15 points)

answer:

what is your question that you ask

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
