the final temperature was -2 F, and that reflects a drop of 13 units, so
-2------0------------------------------------------------------+11.
6 ft= 6x12in= 72 in.
8 ft= 8x12in= 96 in.
12ft=12x12in=144 in
25ft=25x12in=300 in
50ft=50x12in=600 in
72 in, 96 in, 96 in, 144 in, 300 in, 300 in, 600 in
Mean= (72+96+96+144+300+300+600)÷7
1608÷7 = 229.7 inches
Median=middle value in set = 144 inches
Mode= value(s) tha occur most often = 96 inches and 300 inches
Range=difference of largest and smallest values in set = 600-72= 528
Choice A
Answer:
<u>Part 1</u>
<u>Sideways or "horizontal" parabola</u> with a horizontal axis of symmetry.
<u>Part 2</u>
The vertex is the turning point: (-3, 1)
<u>Part 3</u>
Vertex form of a horizontal parabola:
where:
- (h, k) is the vertex
- a is some constant
If a > 0 the parabola opens to the right.
If a < 0 the parabola opens to the left.
Point on the curve: (-1, 2)
Substituting the vertex and the found point into the formula and solving for a:



<u>Part 4</u>
Equation for the given parabola in vertex form:

Equation in standard form:

Interval simply represent the set of numbers containing all numbers between any two numbers.
The representations of
are
and 
From the question, we have:
![(-\infty, -6]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-6%5D)
The above representation is in interval notation.
The interpretation is that;
The highest number in the interval is -6
The equivalent using set notation is:

The equivalent using inequalities is:
