Kara, sammy, liz, and mark each took many samples from the same population of students. the number of students in each of their samples is shown below. the sample means of which person likely showed the least variability. person taking the sample: kara sammy liz mark # of students in each sample: 14 83 46 65 a. mark b. sammy c. kara d. liz

B. Sammy

Step-by-step explanation:

Kara, Sammy, Liz and Mark each took many samples from the same population of students. But the number of students in the Sammy's sample  is largest, hence their mean will have lest variation.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
