From the graph, we can see that the graph has bumps on (0,25) and (5.1, -7) coordinates.
The higher point is (0,25) and lower one is at (5.1, -7).
We need to find to find the interval of the local minimum and value of local minimum.
<em>From the graph, we can see that graph has local minimum is -7 in the interval [4,7].</em>
Therefore, correct option is 4th option.
<h3>Over the interval [4,7], the local minimum is -7.</h3>
Answer:
- 4+1=5
Step-by-step explanation:
over the y axis is square root
Answer:
II. The sum of the residuals is always 0.
Step-by-step explanation:
A least squares regression line is a standard technique in regression analysis used to make the vertical distance obtained from the data points running to the regression line to become very minimal or as small as possible.
For any least-squares regression line, the sum of the residuals is always zero.
Basically, residuals are used to measure or determine whether or not the line of regression is a good fit or match for the data by subtracting the difference between them i.e the predicted y value and the actual y value, for the x value respectively.
Hence, the statement about residuals which is true for the least-squares regression line is that the sum of the residuals is always zero (0).
Answer:
an = 63(-1/3)^(n-1)
Step-by-step explanation:
This is a geometric sequence with first term 63 and common ratio -1/3.
The equation for the nth term is
an = 63(-1/3)^(n-1).
Answer: B
Step-by-step explanation: Hope this help :D
