. My number is below sea level.
.
If
you increase my number by 100, it is above sea level.
.
If you decrease my number by 25 it is less than -80.
• My number is divisible by 5.
• My number increased by 5 is -70.

This is an impossible question. This is because it is less than -80 but when you add the 5 it is -70 therefore it must be -75. But it saying it is below -80 therefore this is an impossible question

Step-by-step explanation:

The median for the first class is 80 as which means that most students got an 80 on their semester. For the first class, the lowest grade recieved was a 58 and the highest score was an 89. The first class's first quartile was 62 and the third quartile was an 86. Against the first class' scores, the second class had a 56 as the lowest received score and the highest was an 96. The first quartile was an 62 and the third quartile was a 89. The second class however got around an 74 as the average.

DO NOT COPY EXACTLY, JUST CHANGE THE WORDING AS YOU GO AND THIS IS JUST THE INFO PARTS.

Otherwise, Good day to u!   :)
