Step-by-step explanation:
RULER
measurements taken by ruler can be limited due to absolute errors, zero error and uncertainties.
1.) If the end of the ruler is worn out giving rise to a zero error
2.) The calibration of the ruler may give rise to another systematic error if the makings are incorrect.
3.) If the object to be measured is not on the same level as graduated surface of the ruler, the angle at which the scale is viewed will affect the result. This is known as parallax error.
SCALE
Systematic error can occur in a scale when the scale is wrongly calibrated.
Also, reading a scale from different angles introduces a variable parallax error.
random uncertainty could be a parallax error caused by taking readings from different angles. This can be reduced by the use of a mirror behind the scale and viewing normally.
To find the average, divide change in weight by change in weeks.
(149-134)/(8-13)
You should get a negative number, because he loses weight.
