Answer: 6.48
Step-by-step explanation:
Mean is 79.4, population size is 5
MAD formular is addition of variance point /population size
n∑∣xi−xˉ∣
Step-by-step explanation:
well, it is a combination of 2 shapes.
I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.
that would be
2x2 + 6x5 = 4 + 30 = 34 cm²
but you started a valid approach too.
you "sliced" off a narrow rectangle along the whole right side. 7x2.
and that leaves now a 4x(7-2) rectangle.
so,
7x2 + 4x5 = 14 + 20 = 34 cm²
yes, this was my answer.
how did this suddenly appear as your answer ?
Multiply 80 the way you would 100 to get the answer. 100 times .032 equals 3.2, therefore 80 times .032 equals the answer. (2.56)
Answer: The coordinates of point B are (19 , 20).
Step-by-step explanation:
The mid point (x,y) of line joining (a,b) and (c,d) is given by :-
(1)
Given : Point A is located at (3,6). The midpoint of line segment AB is point C(11,13).
Let the coordinates of point B are (a,b) m, the according to (1) , we have
Hence, the coordinates of point B are (19 , 20).
