Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years
If a defibrillator manufacturer claims that its device terminates ventricular fibrillation on the first shock 95% of the time, you should: recognize that this does not mean it will save more lives.
<h3>Defibrillator </h3>
The purpose of defibrillators is to restore a normal heartbeat by shocking or sending an electric pulse to the heart. They are employed to stop or treat irregular heartbeats that are too slow or too fast, or arrhythmia. Defibrillators can also restart the heart's rhythm if it stops suddenly. Defibrillators operate differently depending on the type. People who are having cardiac arrest can be saved by using automated external defibrillators (AEDs), which are increasingly commonplace in many public areas. These gadgets can be used in an emergency by unskilled witnesses. People who have a high risk of developing a life-threatening arrhythmia may benefit from using other defibrillators to avoid sudden death.
