While shopping at the mall, Jonathan saw two toys he wanted to buy. The toys originally cost $15.95 and $11.65,
but they were on sale for off the regular price.

Jonathan paid for the toys with a $20 bill. Which expression can be used to determine how much change Jonathan received?

20-1/3(15.95+11.65)

20-((15.95+11.65)-1/3(15.95+11.65 ))

((15.95+11.65)-1/3(15.95+11.65))- 20

1/3(15.95+11.65)-20

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position

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

Hi i’m not sure how to do question 20 if u could explain how to do it that’d b great
