Answer 1

The 3-day moving average for today's high temperature in St. Louis, calculated from the daily highs of the past three days (95°, 88°, and 95°), is 92.7° degrees when rounded to one decimal place.

Step-by-step explanation:

To calculate today's high temperature in St. Louis using a 3-day moving average, we take the daily high temperatures for the past three days and calculate the mean (average) of these temperatures. For the last three days provided, the temperatures were 95°, 88°, and 95° (yesterday).

The 3-day moving average is:

(95 + 88 + 95) / 3 = 278 / 3 = 92.6667

When rounded to one decimal place, today's high temperature using the 3-day moving average is 92.7° degrees.
