Step-by-step explanation:
<em>The question is incomplete, as the required data to answer the question are missing.</em>
<em>However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.</em>
<em>Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data</em>
<em>Then, make comparison</em>
<em />
To do this, I will use the following assumed datasets.
IQR is calculated as:
is of the upper half
is of the lower half
For Joe, we have:
The median is then calculated as:
For, the lower half:
So:
For the upper half:
So:
When the same process is applied to Sam's data,
Assume that:
<em>Hence, the IQR is 47 points less for Joe's data than Sam's</em>
Answer:
i dont know mabey some one else knows
It's an upside (-) down parabola. The axis of symmetry is the x coordinate of the vertex.
you can easily find this using formula: x= -b/2a
for parabola: ax² + b + c = 0
x = -16 ÷ 2(-4)
x = 2
Answer C
Answer:
I am not sure but i think it is x=-2 or y=-3 it is one of them.
