Capitolo 2, Problema 7a
On a typical day, Sandra may encounter several situations involving measurement. State the name and type of measurement indicated by the units in each of the following:
a. The clotting time for a blood sample is 15 s.
Guida verificata passo dopo passo1
Identify the unit provided in the problem. In this case, the unit is 's', which stands for seconds.
Determine the type of measurement associated with the unit. Seconds are a unit of time, so the measurement is related to time.
State the name of the measurement. The problem specifies 'clotting time,' which refers to the duration it takes for a blood sample to clot.
Combine the type and name of the measurement. The type is 'time,' and the name is 'clotting time.'
Conclude that the measurement indicated by the unit 's' is the clotting time of the blood sample, which is a measurement of time.
