Answer:
x= 2
or it's 0
Step-by-step explanation:
2.8 x
----- = ---- = (2.8)(17.4)=27.52(x)
27.52 17.4
49=27.52(x)
--------------
(27.52) (27.52)
2=x
or:
2.8/27.52= x/1.74
2.8(1.74)=27.52(x)
5=27.52(x)
0=x
Answer:
Area = l × w , where l is length and w is width of the room.
Step-by-step explanation:
Length of the room is given to be l units
Width of the room is given to be w units.
The shape of the room is given to be rectangle.
Also, it is given that the area of the rectangle can be calculated by multiplying its length and the width.
So, in order to calculate the area of the rectangle shaped room we multiply the given length of the room l and the given width of the room w.
Hence, The area of the room is given by :
Area = l × w , where l is length and w is width of the room.

Mean diameter = 44, which is in the 40 - 44 cm group
Step-by-step explanation:
Given the data:
Diameter (cm) - mid point(X) - frequency(F) - - FX
35-39 - - - - 37 - - - - 8 - - 296
40-44 - - - 42 - - - 10 - - - 420
45-49 - - - 47 - - - 13 - - - 611
50-54 - - - 52 - - - 3 - - - 156
55-59 - - - 57 - - - 1 - - - 57
Mean of grouped data:
Sum of (F × X) / sum of F
1540 / 35 = 44
