Asurvey asked eight students about their scores on a history test and whether they studied for the test. the table shows the results of the survey. test scores studied did not study 88 34 90 67 86 80 96 59 which statements about the data sets are true? check all that apply. the mean absolute deviation for the group of students who studied is 12. the mean absolute deviation for the group of students who did not study is 13.5. the data for the group that studied are more spread out than the data for the group that did not study. the data for the group that did not study are more spread out than the data for the group that studied. the data for the group that studied are more clustered around the mean than the data for the group that did not study. the data for the group that did not study are more clustered around the mean than the data for the group that did study.

* The MAD for the people that did not study is 13.5

* The data for the group that did not study is more spread out then the data for the group that studied

* The data for the group that studied is more are more clustered around the mean then the data for the group that did not study.

Step-by-step explanation:

got it right on edge

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
