What are seconds used for?
To know how long something/someone takes to do something.
Convert 10 micrometers to millimeters. Show your work.
0010 micrometers = 0.01 millimeter
Find the standard deviation of 26cm, 20cm, 14cm, 18cm, 22cm. Show your work.
(26+20+14+18+22)/5=20 mean
26-20 20-20 14-20 18-20 22-20 variation
6^2+0^2+6^2+2^2+2^2=80 80/5=16 sqrt(16)=4 Standard deviation
What goes on the x-axis?
Independent variable
What goes on the y-axis?
Dependent variable
Define Qualitative observation
It describes the characteristics of an object.
Explain the difference between mass and weight.
Mass is the amount of matter in an object, weight is based on gravity.
Define Quantitative observation
It involves the same characteristics of an object but it has measurement or count.
