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.

1418
Step-by-step explanation:
g= 440+990-2(440)(990) cos 164
g=193600+980100-2
g=193600+980100+837451.1895
g= 2011151.1895 Square root and round
Answer:
The correct option is A.
Step-by-step explanation:
The difference between actual value and predicted value is called residual.
Formula of residual is
Where, y is observed value or actual value and is predicted value.
The value of residual is 1.4 and option A is correct.
