What conclusion can be determined from the dot plot below? A. The median of the data set is 3. B. The mean of the data set is 3.

RSB [31]

Given:

Consider the below figure attached with this question.

To find:

The conclusion that can be determined from the dot plot.

Solution:

The number of dots in the dot plot is 15. So, the number of observations is 15 and option D is correct.

The data set represented by the dot plot is:

2, 2, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6

Number of observations is 15, which is an odd number. So, the median of the data set is:

$Median=\dfrac{15+1}{2}\text{th term}$

$Median=\dfrac{16}{2}\text{th term}$

$Median=8\text{th term}$

$Median=4$

The median of the data set is 4. So, option A is incorrect.

Mean of the data set is:

$Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

$Mean=\dfrac{2+2+3+3+3+4+4+4+4+4+5+5+5+6+6}{15}$

$Mean=\dfrac{60}{15}$

$Mean=4$

The mean of the data set is 4. So, option B is incorrect.

The range of the data set is:

$Range = Maximum - Minimum$

$Range = 6-2$

$Range = 4$

The range of the data set is 4. So, option C is incorrect.

Therefore, the correct option is D.

Answer:Compare the constants of the two variables.

changed at the same rate, or by the same factor, then they are directly proportional. For example, since the x-coordinates changed by a factor of 2 while the y-coordinates also changed by a factor of 2, the two variables are directly proportional.

Which question can be represented by the equation ? × 1/8 = 3.

Lana71 [14]

Answer:

"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "

Step-by-step explanation:

Modeling of Reality

Sometimes we have a real situation and we want to provide a mathematical model to explain it. But what if we have the model and need to imagine what the situation could be? It calls for our imagination and tries to figure out such a problem, given the answer

We can see a question mark multiplying the fraction 1/8 to produce a result of 3. This is a common proportion problem. This is my approach

"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "

If we solved this question, we have to replace the ? for 24 and say Peter sold 24 pencils and made 24(1/8)=$3
