The constant of variation is: -10
Step-by-step explanation:
The inverse proportion between y and x is given by:
y ∝ 1/x
When the proportionality symbol is removed, the proportionality consatnt is introduced
So
![y = \frac{k}{x}\\k = xy](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bk%7D%7Bx%7D%5C%5Ck%20%3D%20xy)
Putting the values of x and y
x = -2
y = 5
![k = -2 * 5\\k = -10](https://tex.z-dn.net/?f=k%20%3D%20-2%20%2A%205%5C%5Ck%20%3D%20-10)
Hence,
The constant of variation is: -10

Answer:
There would be an 83.3% chance (0.83 chance) that the die would not land on 5.
Step-by-step explanation:
Use the probability formula:
(desired events over total events)
- There are 5 desired events. (The events that the die would not land on five)
- There are 6 total events.
![\frac{desired}{total} =\frac{5}{6}= 0.8333333](https://tex.z-dn.net/?f=%5Cfrac%7Bdesired%7D%7Btotal%7D%20%3D%5Cfrac%7B5%7D%7B6%7D%3D%200.8333333)
Rounded to two decimal places, there would be a 0.83 chance that the die would not land on 5.
I think that the correct answer would be : x/5 - y = 10
I hope that this helps you !
