Question
example
step by step
while standing on a moving walkway at an airport, you are carried forward
20 feet every 10 seconds for 1 minute.
enter a function that models this situation. determine a domain from the situation, graph the function,
and identify the range. use set notation for the domain and range.
part 1 out of 2
enter the function and identify the domain.
the walkway's rate of motion is
a function is d(t)=
t, where t is the time in seconds and d is the distance in feet.
the domain is {t | (select)

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
