answer:

chris: -1.1315.

karen: -1.6038.

step-by-step explanation:

the z-score = (x - m) / d       where m = the mean, d = the standard deviation and x is the individual score.

chris: z-score = (185.13 - 185.52) / 0.327

= -1.1315.

karen: z-score = (110.13 - 110.3) / 0.106

= -1.6038.

a dilation is a type of transformation that enlarges or reduces a figure by a scale factor,

in the dilation about origin by a scale factor k,

the coordinates of the transformed figure can be get by the following rule,

here k = 4,

thus, the dilation rule will be,
