The central sleep apnea is a condition, in which the person rapidly stops and starts breathing during the sleep.

<span>Roughly 5.6 years would be added to the average lifespan of the U.S. population. The test's lifespan increased from 719 to 770, or by 1.071. Multiplying the average lifespan by this amount would equal 84.609.</span>
exact form : c= 38/15
decimal form : c= 2.53333333333
mixed number form: c= 2 8/15
mark brainliest :)
