Answer:
Step-by-step explanation:
The homework grade, to the nearest integer, for a student with a test grade of 68 is 69.
Step-by-step explanation:
The general form of the linear regression equation is:
Here,
y = dependent variable = test grade
x = independent variable = homework grade
a = intercept
b = slope
1. BC is 1+3=4 (units)
2. AD is 3+5= 8 (units)
3. Draw the altitude CH from point C, as shown in the figure.
4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.
5.



6. AB=CD=4.47 because the trapezoid is isosceles.
7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)
I do not know exactly what you are trying to ask, but yes. Any time that the slope is greater than 0, the graph will increase in a positive direction.
