Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²
Answer:
types of reading instruction - independent variable
reading comprehension of students - dependent variable
Explanation:
When it comes to the "experimentation" of a study, there are factors or variables that are being considered. These are <em>"independent variable</em>" and <em>"dependent variable."</em>
Independent variable refers to the variable that is being controlled. This affects the dependent variable. The influence of the independent variable on the dependent variable is <u>very important.</u>
So, in the situation above, the independent variable is the "types of reading instruction for a school year" while the dependent variable is the "reading comprehension" of the students.
<em>This means that the reading comprehension of the students will largely depend on the types of reading material.</em>
Thus, this explains the answer.
