If the perimeter of a large square is 20cm longer than that of a small square, the difference in area is 35cm2 What is the length of each side of the two squares?
The perimeter of large square is 20cm longer than that of small square
Then, the side length of large square is 20 / 4 = 5cm longer than that of small square
If the side length of a small square is x cm, the side length of a large square is x + 5 cm
(x+5)²-x²=35
10x+25=35
x=1
x+5=6
The side length of small square is 1 cm, and that of large square is 6 cm

Parameter estimation problem: let the population obey the uniform distribution of θ - 1 / 2 to θ + 1 / 2, x1, X2 Xn is the sample from the population, and the sample mean is x average Let the population obey the uniform distribution from θ - 1 / 2 to θ + 1 / 2, x1, X2 Xn is the sample from the population. The mean value of sample X and (x (1) + X (n)) / 2 are unbiased estimates of θ. Which is more effective? The key is how to find the variance of (x (1) + X (n)) / 2. X (1) represents the minimum value of n samples, and X (n) represents the maximum value of n samples
