Answer:
36
Step-by-step explanation:
The middle number 28 is the median.
The upper quartile is 'middle' number of the last 4 numbers.
So its the mean of 35 and 37 = 36 (answer)
A.)
Slope:-1/4
Y intercept: (0,13/4)
X intercepts:(13,0)
B.)
X intercepts:(3,0)
Y intercepts:(0,-3)
In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:
is a constant which helps to determine whether the parabola opens up or down. If 
, then the parabola opens downward and if 
, the parabola opens upwards
is the vertex of the parabola
By looking at the graph, we can first see that the graph opens downwards, meaning that . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.
The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:
The answer is a, 
.
5. Volume of sphere = 4/3 x pi xr ^3
Volume = 4/3 x 3.14 x 2^3 = 33.49 cubic feet.
6 . Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 2^2 x 3 = 37.68 cubic meters
