Answer:
A.
mean=82.286
Rounded to the tenths place would be= 82.3
Step-by-step explanation:
The Mean is found by adding all of the values together
Then dividing it by how many values there are.
In this instance, all the values added up equal 576
576 now will be divided by how many temperatures are recorded.
576/7=82.286
82.286 Rounded to nearest tenth=82.3
