Question

the curiosity rover on the surface of mars recently measured a daily low temperature of -65.19°c
part a
what is the implied range of the actual temperature?
exactly -65.19°c
between -65.18°c and -65.20°c
between -65.191°c and -65.189°c
between -65.1°c and -65.2°c

Explanation:

Step1: Determine the precision of the measurement

The measured temperature is -65.19°C. The last digit (9) is in the hundredths place.

Step2: Calculate the range

The uncertainty for a measurement with two decimal places is ±0.005°C.
Lower bound: -65.19 - 0.005 = -65.195°C (approx -65.19°C when considering significant figures for the options).
Upper bound: -65.19+ 0.005 = -65.185°C (approx -65.20°C when considering significant figures for the options).

Answer:

between -65.18°C and -65.20°C
