Can you pleas me solve this assignment?

The correct answer for the question that is being presented above is this one: "1,903.73."

Solution:
(1) Multiply the percent favored to the Number surveyed
0.60 * 2700 = 1,620
0.55 * 1900 = 1,045
0.40 * 1000 = 400

So the total is 3,065

(2) Get the weighted mean:
Add the total percent favored = 0.66 + 0.55 + 0.41 = 1.61
Weighted mean = 3,065 / 1.61 = 1,903.73

48 in.

Step-by-step explanation:

We know that the dimensions are 144 by 96.

144  = 96(quotient) + remainder,

144 = 96(1) + 48

Solution: side of largest square = 48
