To calculate the mean absolute deviation of 1,2,3,4,5,6,7 , we start by finding the mean; (1+2+3+4+5+6+7) =28/7 = 4 . Next, we determine the absolute differences of each data point from the mean (x-μ) = -3,-2,-1,0,1,2,3 . The absolute values are 3,2,1,0,1,2,3 . Now we compute the mean of these absolute differences, 3+2+1+0+1+2+3 = 12 = 12/7 = 1.7143 . Thus, the mean is 4, and the Mean absolute deviation comes out to be 1.7143
Within geometry, exterior angles are defined as those angles formed between any side of a polygon and the extension of an adjacent side, as demonstrated in the diagram.
Observing the figure, angles 2 and 3 arise from a side of the triangle and a line extended from the following side. Likewise, angles 5 and 6 are created similarly. Thus, these four angles are classified as exterior angles.
If he initially had 150 to spend on 3 pairs of pants and was left with 30 afterward, the equation would be 3x + 30 = 150. If you're interested in figuring out the price per pair, it comes out to $40
