Answer:
11/19
Step-by-step explanation:
Firstly, we need to know the total number of instructors. This is equal to 7+5+4+3 = 19 instructors.
The probability of selecting a science instructor is 4/19
The probability of selecting a math instructor is 7/19
The probability of selecting either a science or a maths instructor is 4/19 + 7/19 = 11/19
Answer:
![y=\frac{96}{x}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B96%7D%7Bx%7D)
Step-by-step explanation:
So when x and y, vary inversely, it means that the product of x and y will remain constant such that:
. This means that the function can be defined as
by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation:
, which can be defined as ![y=\frac{96}{x}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B96%7D%7Bx%7D)
