It is summation.
p.s. Excuse the scribble.
Step-by-step explanation:
This is a piece-wise function. The three intervals we need to worry about are [0, 1), [1,2], and [2,4].
Separate the functions into their pieces and draw out the individual graphs. Place them together onto the graph within their respective intervals.
Answer:
(-1, 5/2)

That is what I got
Answer:
D. With a p-value of 0.305, we do not have statistically significant evidence that the population mean distance traveled to class is different for men and women.
Step-by-step explanation:
What we are testing?
If the distance students travel to get from class is statistically different for men and women.
How we take the decision?
The significance level is the standard of 0.05.
If the p-value is greater than 0.05, there is no evidence that the distances are statistically different for the population.
If the p-value is less than 0.05, there is evidence that the distances are statistically different different for the population..
In this question:
p-value: 0.305 > 0.05, so there is no statistically significant evidence that the means are difference, and the correct answer is given by option d.
Find the gradient so (-5-3)/(2+1) =-8/3 input it in y=mx+c and also use the coordinates from the question
So it becomes
3=-8/3 (-1) + c
C=1/3
Y=-8/3 x+1/3
