Answer: The relative frequency of column A in group 1=
The relative frequency of column B in group 1=
The relative frequency of column A in group 2=
The relative frequency of column B in group 2=
Step-by-step explanation:
The relative frequency is the ration of each frequency by the total value in particular group.
For group 1 : Total =102+34=136
The relative frequency of column A in group 1=
The relative frequency of column B in group 1=
For group 2 : Total =18+14=32
The relative frequency of column A in group 2=
The relative frequency of column B in group 2=
Answer:
which number to solve, it kinda seem difficult
Answer: x = 3
Step-by-step explanation:
x+5 = 3x-1
+1 +1
x+6 = 3x
-x -x
6 = 2x
/2 /2
3 = x
That arrow helps a lot.
One
Scale factor = 21/14 = (3*7)/(2*7) = 3/2 the sevens cancel out.
Two
Scale factor = 24/18 = (6 *4) / (6 * 3) The 6s cancel out
Scale factor = 4/3
Answer:They bisect each other at right angle (angle 90)
