Situation: A 14 gram sample of a substance that's used
to preserve fruit and vegetables has a k-value
of 0.1095.
Find the substance's half-life, in days.
Round your answer to the nearest tenth.
Enter the correct answer.
DONE
N = Noe-kt
No = initial mass (at time t = 0)
N= mass at timet
k= a positive constant that depends on the
substance itself and on the units used to
measure time
t = time, in days

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction

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
