Depends on the type of drug test and how often you smoke. If it's a urine test, typically a month or so if you're a frequent user. A hair test can go up to 3 months back unless you have 18" of hair which then can go back 180-360 days. If you shave your head, they're then required to take body hair or a blood test. I'm unsure how long a blood test dates back.
1). Trim your data prior to analysis, making it easier to focus on analysis.
2). Never perform analysis on the master
copy of your data.
3). Base your hypothesis in theory, not on a hunch (or on the data).
4). Accept that you may not find "significance".
5). Check assumptions BEFORE you analyze your data.
6). Carefully select your analysis.
Answer:
2.5 g/
Explanation:
The problem is asking for "density," so we have to know its formula first before we can solve.
Density (ρ) =
We know the mass of the cube (21.6g) but we don't know its volume. Let's check out the formula for volume.
Volume = length x width x height
Let's substitute the values.
Volume = 1.2 cm x 2.4 cm x 3 cm = 8.64
Now that we have the volume, we can already solve for the density of the cube.
Density = = 2.5 g/
