Mustafa, heloise, and gia have written more than a combined total of 2 2 2222 articles for the school newspaper. heloise has written 1 4 4 1 ? start fraction, 1, divided by, 4, end fraction as many articles as mustafa has. gia has written 3 2 2 3 ? start fraction, 3, divided by, 2, end fraction as many articles as mustafa has. write an inequality to determine the number of articles, m mm, mustafa could have written for the school newspaper.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

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
