Answer:
A
Step-by-step explanation:
The mean/average is the sum of all the numbers divided by the number of numbers.
It is given that mean is 4.5 points. <em>At this point, it means that there might be students scoring less than 4.5 and students scoring greater than 4.5 BUT the average comes to be 4.5</em>.
BUT SINCE IT IS GIVEN THAT EACH STUDENT SCORED THE SAME, the only way that this can be true is when EVERY STUDENT SCORES 4.5. This way, the AVERAGE/MEAN will be 4.5
Hence, the correct answer is A.
P = 2( l + w)
Length: 2y
Width: y - 4
P= 22 inches
2(2y) + 2(y - 4) = 22
4y + 2y - 8 = 22
4y + 2y = 6y and add (-8) on both sides of the equation to equal: 6y = 30
Divide 6 from both sides of the equation and you get: y = 5
Check:
4(5) + 2(5) - 8 = 22
20 + 10 - 8 = 22
30 - 8 = 22 ✅
Common ratio means the multiplier applied to a previous year to get the next year's value.
For example, production was 1000 units this year, the common ratio is 1.62, so next year production is 1.62*1000=1620, with an increase of 620 units over preceding year of 1000.
So the percentage change is 620/1000 = 0.62 = 62%.

To find the average, divide change in weight by change in weeks.
(149-134)/(8-13)
You should get a negative number, because he loses weight.
