Answer:
Average for zero: 51.1
Average for two: 76.3
Average for four: 87.4
Average for six: 103.3
Blank 1: 51.1
Blank 2: 76.3
Blank 3: 87.4
Blank 4: 103.3
Explanation:
The above answers gave the average of each of the set of numbers.
To calculate the average of a set of numbers, It is done by simply summing the numbers and then dividing the numbers by the total number of values in that set of numbers.
From the data given, zero, two, four and six all have their set of numbers. So, with those values, the average was calculated.
Answer:
The correct answer is option 'D':During ventricular systole, the left ventricle generates more than 120 mmHg
.
Explanation:
A blood pressure of 120 mm Hg means that during the ventricular systole the blood leaves the ventricles to the rest parts of the body the pressure that it exerts on the walls of the arteries equals pressure exerted by a column of 120 mm of mercury. At the peak flow the pressure should be just exceed 120mm Hg in order to initiate circulation. The excess pressure is needed as we need to overcome the resistance of the blood in the arteries that is at a pressure of 120 mmHg
