Answer:
How long the ball was in the air
Step-by-step explanation:
3.5 seconds is the amount of time that the ball's height starts from 0 meters and ends to 0 meters.
We determine the minimum and maximum scores that Juan needs to get in order to be within the strict average range. We let x be his score.
minimum:
74 = (82 + x) / 2
The value of x from the equation is equal to 66.
maximum:
80 = (82 + x )/2
The value of x from the equation is equal to 78.
Hence, Juan's score should fall between 66 and 78, inclusive.
Answer: <em> 66 ≤ x ≤ 78</em>
