Answer:
so it would be (7x-4)+(5x+8) = 160
x=13
Answer:
Answer: The mean increases by 3
Step-by-step explanation:
The original data set is
{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}
The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.
The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77
If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80
So in summary so far
old mean = M = 77
new mean = N = 80
The difference in values is N-M = 80-77 = 3
So that's why the mean increases by 3
Answer:
Step-by-step explanation:
Based on the exponent rule, subtract the exponent with the numerator and the denominator.
So, subtract 3 and -8
3-(-8)
3+8
11

Answer:
2
Step-by-step explanation:
The slope given two points is found by
m= (y2-y1)/(x2-x1)
= (2 - -6)/(2 - -2)
=(2+6)/(2+2)
=8/4
