Question

How many students scored at least an 8 on the quiz?

Answer 1

Answer: 11 (choice C)

====================================================

Step-by-step explanation:

Count the number of x's that are over the 8, 9 and 10

• There are 6 x's over the "8"
• There are 3 x's over the "9"
• There are 2 x's over the "10"

That's a total of 6+3+2 = 11 x's

This means 11 students scored at least an 8, i.e. they got 8 or better.

Answer 2

The number of students who scored at least 8 in a quiz means,the total number of students that scored 8 marks and above

The number of students that scored 8 marks from the dot plots is

`=6`

The number of students that scored 9 marks from the dot plot is

`=3`

The number of students that scored 10 marks from the dot plot is

`=2`

Therefore,

The number of students who scored at least 8 in a quiz will be

`\begin{gathered} =6+3+2 \\ =11 \end{gathered}`

Hence,

The final answer is OPTION C
