Allegiant airlines charges a mean base fare of $89. in addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. these additional charges average $35 per passenger. suppose a random sample of 60 passengers is taken to determine the total cost of their flight on allegiant airlines. the population standard deviation of total flight cost is known to be $37. use z-table. a. what is the population mean cost per flight? $ b. what is the probability the sample mean will be within $10 of the population mean cost per flight (to 4 decimals)? c. what is the probability the sample mean will be within $5 of the population mean cost per flight (to 4 decimals)?

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

is there a question here?
