Answer: 5 + 11n = 13n
Explanation:
1) Cost of n visits for a student that is a member
a) Frequent visitor program fee: $5
b) cost of n tickets at $11 each: $11n
c) total cost: $5 + $11n
2) Cost of n visits for a non-member student
a) $13n
3) Equal cost condition:
5 + 11n = 13n ← answer
That is the equation requested, which you can solve to find the number of visits for which the costs are equal:
5 = 13n - 11n
5 = 2n
5/2 = n
2.5 = n
Therefore, 3 visits in a year justifiy the cost of being a member.
If function is 'F' the the inverse would be F^-1 or 'F to the power of negative one.'
Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So,
So, we can apply normal approximation.
Mean = 20
Standard deviation =
Since
So, Probability that fewer than 30 but a packet after testing a free sample is given by
Hence, our required probability is 0.99338.
Answer:
1 hour 54 minutes
Step-by-step explanation:
1 hour and 9 minutes + 45 minutes gives your answer. However, since 45+9=54, this is convenient, since now we don't need to carry. Thus, 1 hour and 54 min is your answer.
Hope this helps!
Answer:
y=3/10;X=-7/10
Step-by-step explanation:
put y=x+1 into where you find y.
solve for X which is -7/10
and put -7/10 into the second equation and solve for y. which is also =3/10
