Answer:

  • absolute error: 0.4 kg
  • relative error: 6.1%

Step-by-step explanation:

The absolute error is the difference between the estimate and the actual weight:

  7.0 kg -6.6 kg = 0.4 kg . . . . absolute error

__

The relative error is the ratio of the absolute error to the actual weight:

  (0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error

2. 5x

3. 6\frac{7}{x}

4. 4x-2x+15

5. (6+x)^2

Step-by-step explanation:

To write expressions remember these key words:

  • a number is a variable like x
  • sum is +
  • difference and subtracted is -
  • quotient is ÷
  • product is ×
  • reciprocal means flip like \frac{1}{9}---> \frac{9}{1}
  • square is an exponent of 2 like x^2

1. x+4x

2. 5x

3. 6\frac{7}{x}

Remember a quotient would be \frac{x}{7}but the reciprocal is \frac{7}{x}.

4. 4x-2x+15

5. (6+x)^2

Homogeneous means similar, it can be observed on the graph as well that the data for the year 2009 is less variant
