The teacher made progress in standardizing the test scores from the beginning of the year to the end. The MAD tells us this because the difference in the teachers scores from the mean is less at the end. The Mean Absolute Deviation is a measure of variability, and the smaller the number, the less variability there is in the answers. So, in this example there are more scores closer to the average than when they first graded the essays.
Answer: 1.029 tons/m³
Step-by-step explanation:
Density of sea water may varies for different temperature but at 25°C the density of sea water is taken as 1029 kg/m³.
Density of sea water is 1029 kg/m³
1 tons=1000 kg
1 kg=0.001 tons
Density of sea water=1029×0.001 tons/m³
=1.029 tons/m³
hence the density will be 1.029 tons/m³
2 goes into both evenly. That would be one of the main ones.
