Mathematics: Euclidean distance can be used to calculate the dissimilarity between two observations. Let u = (25, $350) correspond to a 25-year-old customer that spent $350 at Store A in the previous fiscal year. Let v = (53, $420) correspond to a 53-year-old customer that spent $4,100 at Store A in the previous fiscal year. Calculate the dissimilarity between these two observations using Euclidean distance. a. 66.21 b. 88.57 c. 72.28 d. 75.39

Option D

75.39

Step-by-step explanation:

When provided with the co-ordinates (x, y) and(a, b) then the distance between them is given by $\sqrt {(x-a)^{2}+(y-b)^{2}}$

Since u = (25, $350) and v = (53, $420) then the Euclidean distance will be

$\sqrt {(53-25)^{2}+(350-420)^{2}}=75.3923073\approx 75.39$
