The data set shows the high temperatures during a week in august:

sunday monday tuesday wednesday thursday friday saturday
103 101 99 100 89 99 98

when calculating the average high temperature for the week, mrs. ortiz said that thursday's data should be excluded because a cold front moved through that day.

evaluate this claim by selecting the statement that best reflects why the reasoning is either correct or flawed. (1 point)

a)the reasoning is flawed. even though thursday's temperature is an outlier, it occurred during that week and there is no reason to exclude it.

b)the reasoning is flawed. thursday's temperature is not an outlier.

c)the reasoning is correct. thursday's temperature is an outlier, and excluding it will lower the mean.

d)the reasoning is correct. thursday's temperature is not an outlier, but it should be excluded because it was the coolest day of the week

For problems 7–10, state a reasonable domain for the problem statement, find the inverse function f –1(x), and identify the independent and dependent quantities of the inverse. 7. gary is jogging. the total distance he has traveled, in miles, can be estimated using the function f(x) = 9x, where x is his jogging time in hours. 8. camryn sells computers. she earns commission for her computer sales plus a fixed wage for each day she works. her daily earnings, in dollars, can be estimated using the function f(x) = 0.15x + 50, where x represents her computer sales in dollars. 9. the distance a motorboat travels, in meters, can be estimated using the equation f(x) = 1.9x2, wherexisthetimeinseconds,for0≤x≤10. 10. a rock band is selling tickets to a concert at a theater. the band earns money for each ticket sold, but has to pay some of the earnings to the theater. the total money earned by the band can be estimated using the function f(x) = 7.5x – 300, where x is the number of tickets sold.
