Question

Mathematics: Asurvey asked eight students about their scores on a history test and whether they studied for the test. 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

Begin by writing the formula;

y=abˣ
y=25(0.75)ˣ

Now calculate vertical height for one way, y=25(0.75)ˣ using sum of geometric series

S=a₁(1-rⁿ)/1-r
S=25(1-0.75¹⁰)/(1-0.75)
S=94.368 m (in one direction).

Multiply by 2 since you also need to consider the distance travelled when going down; 94.3+94.3=188.737 m

Since 25 is not initially accounted in this sum;

188.737+25=213.737 m

Hope I helped :)
