7 1/15 to the nearest whole would be 7. 3 4/5 to the nearest whole would be 4.
7 – 4 = 3
The ball will hit the ground at 0.125 seconds
<h3>
Quadratic function</h3>
The equation of the function is a quadratic function, and the function is given as:

When the ball hits the ground, the value of h is 0.
So, the equation of the function becomes

Subtract 2t from both sides of the equation

Divide both sides by -2t

Divide both sides by 8

Hence, the ball will hit the ground at 0.125 seconds

Answer:
The correct answer to the following question will be "60 students".
Step-by-step explanation:
Marta will be taking a sampling frame from some kind of 600 student group.
Mean,
N = 60
Although the sampling method could perhaps consist of the following components 10% of the population,
⇒ 
⇒ 
In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.
