Question

se considera fractile ordinale X. calculati (X:y)².​

Answer 1

Răspuns:

Explicație pas cu pas:

x= 2/3 * 4/3 - 1/5 *5/18

x= 8/9 -1/18

x= 16/18 - 1/18

x= 15/18

x= 5/6

y = 3/8*3/1 + 1/5 *15/4

y= 9/8 +3/4

y= 9/8 +6/8

y= 15/8

(x : y)² = (5/6 * 8/15)²

(x : y)² = (20/9)²

(x : y)² = 400/81
