Earth’s orbital speed around the Sun is closest to OC) 850 mi/h
Explanation:
The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.
A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat.
We need to find how many liters would that be.
We know that, 1 litre = 1000 milliliters
1 mL = 0.001 L
To convert 80 mL to litres, we can do it as follows :
80 mL = (80 × 0.001) LL
= 0.08 L
Hence, he stroke volume of a person is 0.08 L/beat.

Answer:
The correct answer is option D. "Null hypothesis".
Explanation:
Null hypothesis is characterized by stating that there is no difference between the specified populations, which is the opposite of the alternative hypothesis that states that there is a difference between the populations. Since the hypothesis included in the question states that "There will be no difference in the number of adverse events...", it is concluded that is an example of null hypothesis.
