Identify the means-to-mad ratio of the two data sets, expressed as a decimal.

data set mean mean absolute deviation (mad)
1 4.3 1
2 4.9 1.2

Data set      Mean         MAD
1                    4.3               1
2                    4.9               1.2

The means-to-MAD ratio is simply presenting the Mean and MAD in a fraction form wherein the Mean is the numerator and the MAD is the denominator and simplifying the fraction.

Data Set 1: 4.3/1 = 4.3
Data Set 2: 4.9/1.2 = 4.08

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
