7. because you would put the number set into order from least to greatest first, ti would look like this: 2,3,4,5,9,10,12,12. then go to the middle, crossing one from each side off at one time. Then you get 5 and 9 in the middle. Then the middle between 5 and 9 is seven, you can check this by: 5+9=14, then 14/2= 7.
Your median is 7.
Answer:
C
Step-by-step explanation:
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
The living room is rectangular. We would find the area by applying the formula for calculating the area of a rectangle which is expressed as
Area = length x width
From the information given,
internal length = 5.2
internal width = 2.95
Thus,
internal area of the living room = 5.2 x 2.95
internal area of the living room = 15.34 m^2
