Answer:
3/4
Step-by-step explanation:
The mean of a data set is synonymous with the average. To find the mean, add up all the values in the data set and then divide by the number of elements.
From the table, there is 12 values. Thus, add up all the 12 values and then divide by 12:

Simplify:

Reduce:

Therefore, the mean of the data set is 3/4.
For the data set, this means that the average person guesses the temperature too high by about 3/4°F.
(Note: the symbol of x with a bar over it denotes the mean of a set)
18.5 hours
To solve this problem, you first need to figure out the average amount of money per hour the worker earns.
That would be the base salary plus the average tips per hour. So
$6 + $12 = $18
Then to figure out how many hours the worker needs to work, divide the goal by the hourly earnings. So
$333 / $18 = 18.5 hours.
Therefore on average, it will take 18.5 hours to earn $333, assuming a
base salary of $6/hour and an average of $12 in tips per hour.
