The problem describes a function that expresses the concentration of an antibiotic in mg/dl vs time in hours as:

We need to find the first value of t such that

It means that

Operating with the inequality

Rearranging and dividing by 2, we have a polynomial inequality:

Factoring

There are two possible values for t, both valids because they are positive

We need to find the first value, i.e.

Now for the graphic method, we plot the graph for the function and a horizontal line at c=4 to find the values of t.
The graph is shown in the image provided below. We can see both values where the funcion and C=4 intersect. Both values coincide with the previously analitically found values
The same way you add and subtract any pair of fractions. You need to make sure the denominators are equal. Once they are equal, you can add or subtract the numerators and place the result over the common denominators.
The trick is to realize what your choices are.
if m or n or both are divisible by 5, then 2mn will be divisible by 5
I don't know if you know about x mod(5), but in that case there can only be 4 possibilities for m and n
m mod (5) = +/- 2 or m mod(5) = +/- 1
In the first case m^2 = 4 mod(5) and in the second case m^2 = 1 mod(5) N has the same considerations.
If m and n have the same modular results (both are [say] 2 ) then m^2 - n^2 which be 0
If they are different, then (m^2 + n^2) mod 5 = 0

Answer:
3/10
Step-by-step explanation:
so 1/5 probability
3 is the frequency so
10 times spun
3/10 is the answer
