Allegiant airlines charges a mean base fare of $88. in addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. these additional charges average $37 per passenger. suppose a random sample of 50 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 $39

a. allegiant airline reports a population mean base fare of $89 and a population mean additional fare of $39 per person. 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)?

depending on others is critical to survival. my source is apex!

step-by-step explanation:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
