Final answer:
To calculate the total temperature change over a 5-day period with a daily change of -3.2°F, you multiply -3.2°F by 5, resulting in a total change of -16°F.
Step-by-step explanation:
The question asks for the total temperature change over a 5-day period given that the mean temperature change per day is −3.2°F. To find the total change, you multiply the daily change by the number of days. Since the change is negative, it indicates that the temperature is decreasing each day.
Total change = Daily change × Number of days
Total change = -3.2°F/day × 5 days
Total change = -16°F
The total temperature change over the 5-day period is -16°F.
