What is the standard deviation of the data? A statistics student gave a survey to students which
asked how many first cousins they have. The data from
the first nine responses are shown below.
0 2.38 first cousins
0 2.52 first cousins
6, 2, 7, 8, 8, 8, 5, 10, 10
O 5.65 first gausins
SARE
6.36 first cousins

just keep asking questions until you have a better understanding.

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

the answer that is correct is false
