Answer:
Javier,16,12
Step-by-step explanation:
From the first bag, we can pull a 1,2 or 3. That would go on the first line of the tree diagram
From the 2nd bag, we can draw a 4,5, or 6. That goes on the the second line under each number
From the 3rd bag, we can draw a 7,8, or 9. That goes on the the third line under each number
Javier drew the correct tree diagram.
1,3,5,7,9 are odd numbers. We must have at least 2 of these numbers
1,4,7 2,5,7 3,4,7
1,4,9 2,5,9 3,4,9
1,5,7 3,5,7
1,5,8 3,5,8
1,5,9 3,5,9
1,6,7 3,6,7
1,6,9 3,6,9
There are 16 total where there are at least two odd numbers
Multiples of 4 are 4 and 8
We must have either a 4 or an 8 but not both
1,4,7 2,4,7 3,4,7
1,4,9 2,4,9 3,4,9
1,5,8 2,5,8 3,5,8
1,6,8 2,6,8 3,6,8
There are 12 outcomes

Answer:
14 s
Step-by-step explanation:
We notice that the expression that shows the distance above ground as a function of time, is in fact a quadratic expression (parabola) with negative leading coefficient (-16). this means that the graph of the projectile's distance from the ground is a parabola with branches pointing down, and therefore must have a maximum value at its vertex.
We can then used the formula for finding the horizontal position of the vertex in a quadratic function of the general form 
:
In our polynomial 
, the horizontal variable is the time (t), the value of 
is "-16", and 
is "440". Therefore, the time (horizontal variable) at which the projectile reaches the maximum height is:
So we can round this answer to the nearest integer giving us about 14 seconds.
