Найди дисперсию числового ряда \( 4 ; 9 ;-5 ;-18 \). Заполни пропуски, во всех ячейках округление выполняй до сотых. 1. Среднее арифметическое ряда: \( \frac{(4+9+(-5)+(-18))}{4}=\square \) 2. Квадрат отклонения каждого числа: \( (4-(-2,5))^{2}=42,25 \); \( (9-(-2,5))^{2}=\square \) \( (-5-(-2,5))^{2}=\square \) \( (-18-(-2,5))^{2}=240,25 \). 3. дисперсия: \( \frac{(42,25+132,25+6,25+240,25)}{4}=\square \)
