No association because the dots are just scattered all over the graph
Negative association would be when the dots are going toward downwards
Positive association would be when the dots are going toward upwards
Answer:
x - y = 0
Step-by-step explanation:
General form of equation of straight line is
ax + by = c
that is we have to keep terms containing x and y on LHS and term independent of x and y on RHS.
given
x = y
there, no term independent of x and y
now we have to bring y one RHS
for that we subtract y from LHS and RHS
x - y = y -y
=> x - y = 0
Thus, option x - y = 0 is the correct answer.
Answer: (b) 48 cm
==========================================================
Explanation:
Divide the perimeter of the square over 4 to get the side length s.
s = P/4
s = 48/4
s = 12
The side length of the square is 12 cm. This leads to an area of...
A = s^2
A = 12^2
A = 144
The area of the square is 144 square cm.
The rectangle is 4 cm^2 less than the square's area, so we know the rectangle has area 144-4 = 140 cm^2.
If the length of the rectangle is 14 cm, then the width must be
W = A/L
W = 140/14
W = 10
This is a 14 cm by 10 cm rectangle (note how 14*10 = 140)
The last step is to compute the perimeter of the rectangle
P = 2(L+W)
P = 2(14+10)
P = 2*24
P = 48
You can use the formula P = 2L+2W, but it's effectively the same thing.
The perimeter of the rectangle is 48 cm.
