The stem and leaf plot here shows the current sale prices
katrin2010 [14]

Answer:

Symmetric

Step-by-step explanation:

In the stem and leaf plot above which represents the current sale prices of houses in dollars, we can observe the shape of the distribution seem like that of a bell shape. Most of the data values are concentrated towards the center compared to the concentration at both extremes.

This implies that most of the current sales price is centered close to the median price of roughly 49/50 dollars.

Therefore, the distribution of housing price can be described as roughly symmetric.

What is the rate of change of the area of a circle with respect to the radius when the radius is r=3
gizmo_the_mogwai [7]

Now the formula for the area of a circle is: πr². So we take 3 and just put it into the equation. π·3²=28.27. This is the area of the circle. Now the rate of change I think would just be the difference between the radius and the area of the circle so 28.27-3=25.27.

Mrac [35]

If the sides of the triangle are given. Then Wendell can make a triangular garden using pieces D, E, and F.

<h3>What is the construction of the triangle?</h3>

The process of making a triangle is known as the construction of the triangle.

Wendell makes a triangular garden using pieces D, E, and F.

Where D, E, and F may be a side of the triangle or angle of the triangle.

To make a triangle we need at least one side of the triangle.

If all the angles of the triangle is given then we can not make a triangle because the side of the triangle is unknown.
