Alright Fabian, here's the deal.
First you need to solve the inequality for k. To do this, you have to
a) distribute the -(3k + 4)
b) collect like terms: -k - 3k
c) move the term with k to the left (optional but it's a habit)
d) divide both sides by the coefficient. Check out picture for details.
Answer: The required probability is 0.25.
Step-by-step explanation:
Since we have given that
Radius of the dartboard = 4 in
Area of the dartboard is given by

Radius of the shaded region = 2 in
Area of shaded region is given by

So, the probability that the dart lands in the shaded circular region is given by

Hence, the required probability is 0.25.
For number 7 the answer should be 20%. 10 is 50% and the other 6 is 30%.
