A mathematics professor created a test that was supposed to be mostly easy except for two challenging problems. The scores of th
e students are shown in the dot below what was the most common score
1 answer:
Answer:
The most common score is 89.
Step-by-step explanation:
The dot plot is attached to this question with frequency on the y-axis and the test scores on the x-axis.
From the image attached for the dot plot, the dot bar with the highest frequency is the one with a score of 89. Therefore, 89 is the most common score as it has the highest frequency.
Hope this helps!

Answer:
Mass of the cat = 16800kg
Step-by-step explanation:
The volume of the box = its length * its breath * its height- 4m × 3m × 2m = 24
The standard density of water is 1000 Kg/
By Archimedes principle, the mass of a body floating body is equivalent to the mass of the volume liquid displaced
in this case we have
Mass of water displaced = Density of the water × Volume of the water displaced = 1000 Kg/ × 24
= 24000kg
The mass of the box = Box density × Box volume = 24 × 300kg/
= 7200 kg Hence the mass of water displaced = mass of the foating box + mass of th cat
24000kg = mass of cat +7200kg
mass of cat = 24000kg - 7200kg = 16800kg
