Step-by-step explanation:
Your table was hard to decipher, so I have recreated it here.

(a) In Grade 9, 53 students liked pop music.
FALSE. 53 % of the students liked pop music. We don't know how many students there were.
(b) In Grade 8, 60% of students liked heavy metal.
FALSE. 40 % of students liked heavy metal.
(c) In Grade 8, 10 students liked classical music.
FALSE. We don't know how many students there were.
(d) In Grade 9, 20% of students liked classical music.
TRUE. 0.20 means 20/100 or 20 %.
Add them and dividde by the number of numbers, which is 3.
112 + 109 + 115 = 336
336/3 = 112.
The average is 112.

Answer:
Volume = 175 cm³
Step-by-step explanation:
We can picture this image as a whole rectangular prism, with a part that has been cut out of it.
Step 1: Volume of original prism
We are going to solve the volume of the original prism, with the dimensions of 9, 7, and 5
Step 2: Volume of part cut out
We are solving the volume of that part that has been cut out ( missing space)
- V = 5 * (9-2) * (7-3)
- V = 5 * 7 * 4
- V = 140
Step 3: Total Volume
Now we just subtract the cutout part from the original volume
Volume = 175 cm³
Note, we could have also found the volume by splitting this shape into two prisms with dimensions (9 * 3 * 5) and (4 * 5 * 2). This way would also get us:
- V = (9 * 3 * 5) + (4 * 5 * 2)
- V = 135 + 40
- V = 175
