7. International travel is usually more expensive than domestic travel. A recent survey found that the average per-person cost of a 12-day international
vacation is $1,755. This includes transportation, food, lodging, and
entertainment.
a. If the data are normally distributed with standard deviation $390, find the
percentage of vacationers who spent less than $1,200 per day. Round to the
nearest hundredth of a percent.
b. Find the per-day expense for one of these travelers who had a z-score of
-2.1.
c. If the data are normally distributed with standard deviation $490 instead of
$390, would the answer to question 7b become lower or higher?

what graph

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

none.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
