Answer:

  no

Step-by-step explanation:

The ratios of the two shortest sides are different:

  3/2 ≠ 5/4

so the quadrilaterals cannot be similar.

What conclusion can be made when r, the correlation coefficient between two variables, is 0?
IgorLugansk [536]
The correlation coefficient between two variables, r, is always going to be between -1 and 1.

- If the correlation coefficient is 0, means that there is no strong correlation relationship in one direction or the other direction. 
- If the correlation coefficient is -1, means that these two variables move in opposite directions.
- If the correlation coefficient is 1, means that these two variables move in the same direction.

the cost of circular mirrors is directly proportional to the square of the diameter. a circular mirror with a diameter of 60cm c
defon
When 'y' is directly proportional to 'x', we express this by

y = kx

where 'k' is the constant, which we need to work out first

Cost of circular mirrors = (k) (diameter)²
50 = k(60)²
50 ÷ 3600 = k 

the proportional formula is

y = (1/72)x²

The cost of the mirror when diameter = 90cm

y = (1/72) (90)²
y = 112.5

Answer: $112.50
