IF you are dilating about the origin, which you didn't exactly state, the new coordinates are A' (1/5, 1), B' (2/5, 1/5), C' (0, 4/5). Dilation is all about distance, so you have to move the new coordinates to whatever the scale factor is times the x and y distance. For example, A is at (1, 5), so 1/5 of 1 is 1/5, and 1/5 of 5 is 1, hence your new coordinate for A. It is a fifth of the distance from the origin as its preimage is.
Answer:
2 - 79 years is the mean and 82 years is the median.
Step-by-step explanation:
In a given skewed to the left graph, to be able to distinguish between the two measures of center for this expectancy study, the mean is relatively smaller than the median in a skewed left distribution curve.
In this study, The two measures of center for the life expectancy of US males born in the 2018 are 79 years and 82 years. Thus, 79 years is the mean and 82 years is the median.
