People in the U.S spend 18.8 billion dollars in 2009.
<h3>What is substituting ?</h3>
Substituting in mathematics is putting a specific value in an independent variable to observe a system.
According to the given data
Statins is the top selling drug in US to keep cholesterol in check.
The equation of the sales (S) of statin in billons of dollars x years after is
S - 1.3x = 4.5
The year difference is (2009 - 1998) = 11 years or x = 11
Putting the value of x in the given equation
S - 1.3(11) = 4.5
S = 4.5 + 14.3
S= 18.8
∴ The number of sales of statin is $18.8 billions.

Answer:
9/25
Step-by-step explanation:
I used to struggle on these too, but I'll exaplain the best I can. Firstly, we know that 3 people don't have a cat or a dog, so what we do is we minus that from 25. This becomes 22. Now, we have to add the amount of people who have a cat to the amount of people who have a dog, and then minus it from 22, because that is the amount of people without double ups in the class with at least either one of the pets given. So, 16+15=31. Now, we do 31-22, which is equal to 9. Therefore, 9/25 people, (because the question asked out of random in the class), have a cat and a dog. This is because the double up are the extra amount of people who had more than one pet. Hopefully this was helpful. I'm sorry if it is not as probability is a hard topic to explain.

Answer:
Step-by-step explanation:
Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.
- (0,2) maps onto (0,6).
- (0,4) maps onto (0,12).
- (3,2) maps onto (9,6).
- (3,4) maps onto (9,12).
Therefore, the answers are the second option and the sixth option.
