The inequality that describes the possible values of the expression is:

<h3>What is the lower bound of values of the expression?</h3>
The expression is given by:

To find the lower bound, we try to see when the expression is negative, hence:


Applying cross multiplication and simplifying the 3's, we have that:

From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
<h3>What is the upper bound of values of the expression?</h3>
The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Then:

Hence the bounds are:

A. 40%of 30=12 senior class members.
B. 60% of the class were not senior class members
For this case, the gravitational force is given by:
F = m * g
Where,
m: mass of the object
g: acceleration due to gravity
Substituting values we have:
F = (100) * (9.8)
F = 980 N
Answer:
The gravitational force that is pulling the object to the center of the Earth is:
F = 980 N
Answer:
D
