Answer:
x = 28
Step-by-step explanation:
It gives you the value of the midsegment, which is 16. So you need to set up the equation as:
x + 4 = 2 × 16
You're multiplying 16 (the midsegment) by 2, because the it is <em>half</em> of x + 4, and you need to be able to set both parts of the equation equal to each other.
x + 4 = 32
Then, subtract 4 from both sides:
x + 4 = 32
-4 -4
_________
This gives you the answer of:
x = 28
It is a positive-slope parabola with vertex of (0,16) "concave up"

Answer:
Mean Absolute Deviation = 2.4
Step-by-step explanation:
Find you have to find the mean (average):
3 + 5 + 7 + 9 + 11 = 35
35 / 5 = 7
Mean = 7
The mean absolute deviation is the mean (average) of the distance from the other numbers (absolute means that if the number is negative it turns into a positive):
3 - 7 = 4
5 - 7 = 2
7 - 7 = 0
9 - 7 = 2
11 - 7 = 4
Now we have to find the mean of this numbers:
4 + 2 + 0 + 2 + 4 = 12
12 / 5 = 2.4
Mean Absolute Deviation = 2.4
