Answer 1

`Total = 23(1)/(4)` cups

Explanation:

Incomplete question.

See attachment for line plot

Required

Total cups drank in 10 days

The number of x at the top of each dataset represent the frequency (i.e. number of cups) drank on that day.

To get the total, we simply multiply this frequency by the accompanying dataset.

So, we have:

`Total = 2 * 1(1)/(2) + 1 * 1(3)/(4) + 2 * 2 + 2 * 2(3)/(4) + 3 * 3`

Express fractions as improper fraction

`Total = 2 * (3)/(2) + 1 * (7)/(4) + 2 * 2 + 2 * (11)/(4) + 3 * 3`

Evaluate each product

`Total = 3 + (7)/(4) + 4 + (11)/(2) + 9`

Take LCM

`Total = (12+ 7+16+22+36)/(4)`

`Total = (93)/(4)`

`Total = 23(1)/(4)`
