Math Problem Statement

Find the coordinates of r that represent the weighted average for the given set of points with the given weights: x has a weight of 3, y has a weight of 1.

Solution

To solve the problem of finding the weighted average of the points shown in the image:

Given:

  • Point xx has a weight of 3.
  • Point yy has a weight of 1.

In the weighted average formula for two points, the coordinates of the weighted average point rr are found using the following formula:

rx=w1x1+w2y1w1+w2r_x = \frac{w_1 \cdot x_1 + w_2 \cdot y_1}{w_1 + w_2} ry=w1x2+w2y2w1+w2r_y = \frac{w_1 \cdot x_2 + w_2 \cdot y_2}{w_1 + w_2}

Where:

  • w1w_1 and w2w_2 are the weights of points xx and yy, respectively.
  • x1x_1, x2x_2 are the coordinates of point xx.
  • y1y_1, y2y_2 are the coordinates of point yy.

Approach:

  1. Extract the coordinates of points xx and yy from the graph.
  2. Apply the weighted average formula to calculate the coordinates of point rr.

Let me take a closer look at the graph to extract the coordinates and calculate the weighted average.

from PIL import Image

Load the uploaded image to take a closer look at the coordinates

image_path = '/mnt/data/1725482438727pgxnbmaf.jpg'

Open the image

img = Image.open(image_path) img.show()The image is now open for closer inspection.

To proceed with calculating the weighted average, let's first identify the coordinates of points xx and yy based on the visual information from the graph. Once we have those coordinates, we can apply the formula to compute the weighted average.

Please provide the coordinates of points xx and yy, or I can estimate them based on the image.
