The mean increases when the outlier is removed
Answer:
Step-by-step explanation:
(a - b)² = a² + 2ab + b²
Area of square frame =side²
= (2b - 1)²
= (2b)² - 2*2b * 1 + 1²
= 4b² - 4b + 1
20 minutes because 9/9 is simplified to 1 as 5/5 is simplified to 1
Answer:
x=-9, y=5. (-9, 5).
Step-by-step explanation:
x-3y=-24
5x+8y=-5
--------------
x=-24+3y
5(-24+3y)+8y=-5
-120+15y+8y=-5
-120+23y=-5
23y=-5-(-120)
23y=-5+120
23y=115
y=115/23
y=5
x-3(5)=-24
x-15=-24
x=-24+15
x=-9
