number each material and sort the items in order from lowest (1) to highest (7) Density
- chalk
- copper
- flour
- dry beans
- talcum powder
- wax
- wet sand
Answer: copper > chalk > flour > talcum powder > dry beans.
Explanation:
Density is the compactness of given object.
Basically, it is mass per volume.
copper has the most density
chalk has lesser density than copper.
flour has lesser density than copper and chalk.
talcum powder has lesser density than copper, chalk and flour.
dry beans have lesser density than copper, chalk, and flour.
So, it becomes,
copper > chalk > flour > talcum powder > dry beans.

We intend to estimate the average driving time of a group of commuters. From a previous study, we believe that the average time is 68 minutes with a standard deviation of 12 minutes. We want our 90 percent confidence interval to have a margin of error of no more than plus or minus 1 minutes. What is the smallest sample size that we should consider
Answer: The smallest sample size would be 392.
Explanation:
Since we have given that
Standard deviation = 12 minutes
Mean = 68 minutes
Margin of error = [tex]\pm 1[/tex]
At 90% confidence interval, z = 1.65
So, the smallest sample size that we should consider would be
[tex]n=(\dfrac{z\times \sigma}{ME})^2\\\\n=(\dfrac{1.65\times 12}{1})^2\\\\n=(19.8)^2\\\\n=392.04\\\\n=392[/tex]
Hence, the smallest sample size would be 392.

Answer:
96 full miles.
Explanation:
[tex]33=17.50+0.16m\\0.16m=15.5\\m=\frac{15.5}{0.16}\\m=96.875[/tex]
