PLEASE SHOW YOUR WORK!!
Frazer spent some time building a wall with 650 bricks in. On the first day, he managed to lay 243. He got more and more tired each day and only managed to lay 2/3 of the number of as the day before. How many days did it take him to build the wall?

Captain Salamander is also building a wall with 650 bricks in it. On the first day, he manages to lay 180 bricks. He also gets tired each day and lays 22 fewer bricks than the day before. Who builds the wall before.
You can make a chart with 6 days, Frazer bricks layed, Frazer total number, Captain bricks layed, captain total number.

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
