Answer:
4th row will result in the greatest mean.
Step-by-step explanation:
We are asked to find the row with greatest mean from our given rows.
We will use formula , where,
,
,
Let us find mean of each row using above formula.
Therefore, mean of 1st row is 2.8.
Therefore, mean of 2nd row is 3.
Therefore, mean of 3rd row is 3.2.
Therefore, mean of 4th row is 4.2.
Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
Answer:
<em>Graphs in the figure below</em>
Step-by-step explanation:
<u>Graphs</u>
We are given the functions:
f(x)=3x-1
g(x)=f(x+1)
The graph of f can be drawn by calculating some points. For x={-1,0,1,2}
We calculate y:
y=3*(-1)-1 = -4. Ordered pair: (-1,-4)
y=3*(0)-1 = -1. Ordered pair: (0,-1)
y=3*(1)-1 = 2. Ordered pair: (1,2)
y=3*(2)-1 = 5. Ordered pair: (2,5)
The graph of g is similar to the graph of f, but the x-coordinates are shifted left by one unit:
Ordered pair: (-2,-4)
Ordered pair: (-1,-1)
Ordered pair: (0,2)
Ordered pair: (1,5)
Both graphs are shown in the image provided
