Step-by-step explanation:
Let X the random variable that represent the length of time student of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
We can solve the problem using the z score formula given by:
If we apply this formula to our probability we got this:
And we can find this probability on this way:
And using the normal standard distribution table or excel and we got:
Given:
Total number of tickets = 600
Cost of adult ticket = $6.00
Cost of student ticket = $4.00
Total sales = $2900.00
To find:
The number of tickets of each type.
Solution:
Let the number of adult tickets be x and number of student tickets be y.
According to the question,
...(i)
...(ii)
Multiply equation (i) by 4 and subtract the result from (ii),
Divide both sides of 2.
Put x=250 in (i).
Therefore, number of adult tickets is 250 and number of student tickets is 350.
