I would tell her that her prediction is inaccurate because it isn’t guaranteed that the coin will land on both sides an equal amount of times. It’s possible that the coin could land heads up more often than it could land tails up or the other way around.
The answer to the questions
We can use the formula: y = cx to solve.
c is the scale factor to x.
So, we just need to multiply.
4.5 * 4 = 18cm.

Answer:
4
Step-by-step explanation:
Given that:
Number of beads used to make 4 bracelets = 16
Number of bracelets made = ![y](https://tex.z-dn.net/?f=y)
Number of beads used = ![x](https://tex.z-dn.net/?f=x)
To find:
The constant of proportionality = ?
Solution:
Number of bracelets made is proportional to Number of beads.
i.e.
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
OR
![y=k\times x](https://tex.z-dn.net/?f=y%3Dk%5Ctimes%20x)
Where
is the constant of proportionality.
We are given that:
when ![x = 12, y = 4](https://tex.z-dn.net/?f=x%20%3D%2012%2C%20y%20%3D%204)
Putting the values in the above equation:
![4 = k \times 16\\\Rightarrow \bold{k = 4}](https://tex.z-dn.net/?f=4%20%3D%20k%20%5Ctimes%2016%5C%5C%5CRightarrow%20%5Cbold%7Bk%20%3D%204%7D)
Therefore, the constant of proportionality is <em>4</em>.
