PLEASEEEEEE HELPP ME IM BEGGING LITERALLY ANYONE

Answer 1

Answer: 34 hours (choice C)

Step-by-step explanation

I'll convert the dot plot to a frequency chart.

`\begin{array}c \cline{1-2}\text{Hours} & \text{Frequency}\\\cline{1-2}1.5 & 5\\\cline{1-2}2 & 2\\\cline{1-2}2.5 & 1\\\cline{1-2}3 & 3\\\cline{1-2}3.5 & 2\\\cline{1-2}4 & 1\\\cline{1-2}\end{array}`

Form a new column where we multiply each hour value with its corresponding frequency (example: 1.5*5 = 7.5)

`\begin{array}c \cline{1-3}\text{Hours} & \text{Frequency} & \text{Hours*Frequency}\\\cline{1-3}1.5 & 5 & 7.5\\\cline{1-3}2 & 2 & 4\\\cline{1-3}2.5 & 1 & 2.5\\\cline{1-3}3 & 3 & 9\\\cline{1-3}3.5 & 2 & 7\\\cline{1-3}4 & 1 & 4\\\cline{1-3}\end{array}`

Then add up everything in that new column to get the total number of hours.

7.5+4+2.5+9+7+4 = 34 hours is the final answer.
