What is the area of a rectangle with vertices at (2, 3), (7, 3), (7, 10), and (2, 10)?

Ainat [17]

Given:
x   y
2   3
7   3
7 10
2 10

It is easier to graph these vertices to avoid confusion.

Length: basis is the y-values : 10 - 3 = 7 units
Width: basis is the x-values: 7-2 = 5 units

Area = Length * Width
A = 7 units * 5 units
A = 35 units² Choice D.

The dot plot shows the ages of students, in years, on a basketball team.Each dot represents 1 student.Age (yr)nd the mean (round

Sever21 [200]

As given by the question

There are given that the dot plots that show the ages of students.

Now,

As obtained from the dot plot:

$x=11,\text{ 11, 11, 12, 12, 12, 13, 13, 13, 13, 14, 14, 15, 15}$

Now,

The mean of the given data is:

$\text{Mean}=\frac{Addition\text{ of the total given data}}{\text{Total number of data}}$

So,

$\begin{gathered} \text{Mean}=\frac{Addition\text{ of the total given data}}{\text{Total number of data}} \\ \text{Mean}=\frac{11+11+11+12+12+12+13+13+13+13+14+14+15+15}{14} \end{gathered}$

Then,

$\begin{gathered} \text{Mean}=\frac{179}{14} \\ \text{Mean}=12.8\text{ years} \end{gathered}$

And,

The mode of the given data is:

The mode is defined for the most frequently occurring value

So,

$\begin{gathered} \text{Mode}=\text{most frequently occurring value} \\ \text{Mode}=13 \end{gathered}$

Hence, the value of the mean is 12.8 and the mode is 13.
