Answer:
Step-by-step explanation:
Find attached the first sum.
x denotes horizontal and y denotes vertical
When the value of x is positive, it moves to right side and when x is negative, it moves left sides 'x unit'
When the value of y is positive, it moves to up side and when y is negative, it moves down sides 'y unit'
Answer:
6
Step-by-step explanation:
The outlier is 67.
The mean with the outlier is: 115
(112+ 118 + 120 +67 + 128 + 119 + 121 + 124 + 126) ÷ 9
The mean without he outlier is: 121
(112+ 118 + 120 + 128 + 119 + 121 + 124 + 126) ÷ 8
So, 121 - 115 = 6
Answer: 6
Step-by-step explanation: [▲x4]+[6x3]=6[4+3
6[4+3=42 so if [6x3]=18 then [▲x4] needs to be 24 (24+18=42) ▲=6 as 6x4=24+18=42 (6[4+3)!
Answer:
A: (-2,2) B: (-4,2) C: (-6,4) D: (-4,6) E: (-2,6)
the rule is whenever you are doing a 90 degree rotation, the coordinates go from (x,y) to (-y,x)
