How would i go about answereing this question?

The mean temperature in new york one summer was 86 degrees. if the temperature on july 22 of that summer was 82.1 degrees, what was the deviation from the mean that day?

You would go about it by subtracting mean temperature from the July 22 temperature. That is what "deviation" means. In this cse, you will get a negative number because the temperature was below the summer average on that day.

so would i do this:

82.1 - 86 = -3.9

now that i have the -3.9 would that be the final answer to the question "what is the deviation from the mean that day?"

Yes, in degrees Fahrenheit

To find the deviation from the mean temperature on July 22, you need to calculate the difference between the mean temperature and the temperature on that day.

Step 1: Find the mean temperature

The mean temperature is given as 86 degrees. This is the average temperature for the entire summer in New York.

Step 2: Find the deviation

To find the deviation, subtract the temperature on July 22 from the mean temperature:

Deviation = Temperature on July 22 - Mean temperature

Deviation = 82.1 degrees - 86 degrees

Deviation = -3.9 degrees

The deviation from the mean temperature on July 22 is -3.9 degrees. Keep in mind that a negative deviation means that the temperature on that day was lower than the average temperature for the summer.
