Answer:
![0.14\ lb/in^{3}](https://tex.z-dn.net/?f=0.14%5C%20lb%2Fin%5E%7B3%7D)
Explanation:
Density is defined as mass ler unit volume, expressed as
![\rho=\frac {m}{v}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%20%7Bm%7D%7Bv%7D)
Where m is mass,
is density and v is the volume. For a sphere, volume is given as
![v=\frac {4\pi r^{3}}{3}](https://tex.z-dn.net/?f=v%3D%5Cfrac%20%7B4%5Cpi%20r%5E%7B3%7D%7D%7B3%7D)
Replacing this into the formula of density then
![\rho=\frac {m}{\frac {4\pi r^{3}}{3}}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%20%7Bm%7D%7B%5Cfrac%20%7B4%5Cpi%20r%5E%7B3%7D%7D%7B3%7D%7D)
Given diameter of 2.24 in then the radius is 1.12 in. Substituting 0.82 lb for m then
![\rho=\frac {0.82}{\frac {4\pi 1.12^{3}}{3}}=0.13932044952427\approx 0.14 lb/in^{3}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%20%7B0.82%7D%7B%5Cfrac%20%7B4%5Cpi%201.12%5E%7B3%7D%7D%7B3%7D%7D%3D0.13932044952427%5Capprox%200.14%20lb%2Fin%5E%7B3%7D)
The true statement about the dot plot is 1 has 4 and 0 dots.
Explanation:
- after creating a Bar chart 4 is the right answer.
- The highest among st all the other plots is 1 but 4 shows 3.
- Taking an average from all the data points 3 comes to the right answer.
- Median the central Mid-point is 3.
- Mode also comes to 3.
- It is skewed on the right due to the 1st one.
- Skewed shows the data point either increasing or in decreasing.
- There a to Bi- histograms which has two ups and downs.
- The true statement has to be as Mean=Median=Mode is 3.
