Answer: 
Step-by-step explanation:
Since we have given that
A very large study showed that aspirin reduced the rate of heart attacks by 44%.
we claim that they have a drug that will be more effective than aspirin.
so, our hypothesis would be

So, it will be one tail test.
Hence, 
Answer:
C. 0.1
Step-by-step explanation:
The sum of the probabilities of all possible events must equal 1.
Since there is no probability of purchasing two vehicles ore more, the events are:
- Purchase a new vehicle (0.5)
- Purchase a used vehicle (0.4)
- Purchase no vehicle at all (x)
The probability of not purchasing a vehicle is:

The probability that you purchase no vehicle at all is: C. 0.1
Based on the calculations, Celine would earn a total of $65.00 assuming she delivered 10 packages.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variable.
<u>Given the following function:</u>
y = 20.00 + 0.45(x)
In this exercise, you're required to determine Celine's weekly earnings based on the number of packages she delivered. However, the number of packages delivered by Celine wasn't shown, thus, we would assume a value for the purpose of an explanation:
Assuming x = 10 packages.
Substituting the value of x into the function, we have:
y = 20.00 + 0.45(10)
y = 20.00 + 45
y = $65.00.

Step-by-step explanation:
Answer:
49°
Step-by-step explanation:
Since the angle measures of QPR and RPS add up to 88 degrees, you can set up an equation to solve for x and then RPS.
5x+34+8x+15=88
13x+49=88
13x=39
x=3
RPS=5x+34=5(3)+34=15+34=49°
Hope this helps!
