Question

The "normal" high temperature for a June day in Albemarle is $82^\circ$ (degrees Fahrenheit). Last year, the first ten days of June were unusually hot, with highs of $84^\circ,$ $88^\circ,$ $91^\circ,$ $92^\circ,$ $96^\circ,$ $94^\circ,$ $89^\circ,$ $78^\circ,$ $87^\circ,$ and $81^\circ$. How many degrees above normal was the average high for that 10-day period?

Answer 1

6° F

Explanation:

To get average of 10 days highs, we need to add all and divide by 10.

Average =
`(84+88+91+92+96+94+89+78+87+81)/(10)\\=(880)/(10)\\=88`

And, the normal high temp is given as 82.

How much higher is 88 than 82??

It is 88 - 82 = 6°F above
