We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]

If you solve d = rt for t, you have t = d/r. If we have values for d and r we will fill them into that equation and divide.

. Setting that up so the meters cancel as they should looks like this:

lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours. The t value then is 11.3 hours.
For this data set:
mean = 1.75
standard dev. = 5.6252 or 5.63
HI umm.. I can see the thing that you need help with sorry not trying to be rude but what do you need help with?
