Answer:
1) the number of hours of TV watched
2) quantitative
3) Mean or Median
Completed details of Question
Additional details to the question are as below
1) Identify the variable measured on each student.
2) Is the variable categorical or quantitative?
3) Identify two statistics that the student could use to summarize the variable.
a) Mean or Median
b) Mean or Proportions
c) Mean or Mode
d) Median or Mode.
Explanation to the answer:
1) The variable measured on each student is the number of hours of TV watched
2) The variable is the amount of time, therefore it is quantitative.
3) Quantitative data can be used compare the exact size and extent of difference in two quantities. Therefore, the two statistics that the student could use to summarize the variables would be Mean or Median. Mean will be the average time and Median will be the middle when the amount of time is ordered from least to greatest.

Might not be answer but.
Step-by-step explanation:
Parallel lines are coplanar lines (in the same plane) that never intersect (never cross each other). The slope of a line measures its steepness (or its angle from the horizontal). Lines that are parallel have the same steepness (or the same angle from the horizontal).
Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
