Answer:
y = 2.4
Step-by-step explanation:
first distribute into the parenthesis' -
2(y-3) = 1.2 -y
2y - 6 = 1.2 - y
+y +y
3y -6 = 1.2
+6 +6
3y = 7.2
/3 /3
y = 2.4

Answer:
see attached for a graph
x = 0.5 when y = 1
Step-by-step explanation:
The graph has a y-intercept of -1, which is halfway between 0 and -2. It goes up 4 units (2 vertical grid spaces) for 1 unit to the right (1 horizontal grid space). It seems to cross y = 1 at about x = 1/2.
x = 1/2 when y = 1.
Answer:
Step-by-step explanation:
We need to simplify
We collect LCM to get;
Therefore:
Also we need to simplify:
We collect LCM to get;
Therefore
Answer: The mean increases by 3
-----------------------------------------------------------
-----------------------------------------------------------
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
