The 6:00 a.m. temperatures for four consecutive days in the town of Lincoln were -12.1 C, -7.8 C, -14.3 C, and 7.2 °C. What was the average 6:00 am temperature for the four days?

Answer 1

See explanation.

Add up all of the numbers in the set, then divide the total by the total number of measured values to find the average (mean) value of the numbers.

#bar(x)=(x_1+x_2+...+x_n)/n#

Here it is:

n = 4

#bar(x)=(-12.1+(-7.8)+(-14.3)+7.2)/4#

#bar(x)=-27/4#

#bar(x)=-6.75#

Answer: The average temperature is #bar(x)=-6.75#
