Six students measure the acceleration (in meters per second per second) of an object in free fall. the measured values are: 10.56, 9.52, 9.73, 9.80, 9.78, 10.91.the students want to state that the absolute deviation of each measured value xfrom the mean is at most d. find the value of d.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
