Describe the difference between plots that show a strong correlation and plots that show a weak correlation.

GalinKa [24]

The data points are a little closer for a weak correlation, and you can see that there is some sort of relationship between these factors.

Data points for a strong correlation are in close proximity to one another, making it possible to build a line by imitating their pattern.

A statistic called correlation gauges how much two variables change in connection to one another.

Correlation and diversification, the idea that certain types of risk can be reduced by investing in assets that are not connected, are closely related concepts.

Correlation cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.

A scatter plot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.

A piece of cardboard is 1 meter by 1/21/2 meter. A square is to be cut from each corner and the sides folded up to make an open-

12345 [234]

Answer:

The maximum dimensions of the box:

Length of the box = 0.788676 m

Breadth of the box = 0.288676 m

Step-by-step explanation:

Original piece of cardboard is a square with sides of length s.

Length of the card board = l = 1 m

Breadth of cardboard = b = 1/2 m = 0.5 m

Squares with sides of length x are cut out of each corner of a rectangular cardboard to form a box.

Now, length of the box = L = 1 - 2x

And breadth of the box = B = 0.5 - 2x

Height of the box ,H = x

Volume of the box ,V= L × B × H

$\frac{dV}{dx}=\frac{(1 -2x)(0.5-2x)x}{dx}$

$\frac{dV}{dx}=\frac{d(0.5x-3x^2+4x^3)}{dx}$

$\frac{dV}{dx}=0.5-6x+12x^2$

$\frac{dV}{dx}=O$

x = 0.394338 , 0.105662

$\frac{d^2V}{(dx)^2}=-6+24x$

When , $x=0.105662$ , $\frac{d^2V}{(dx)^2}$ (maxima)

The maximum dimensions of the box:

Length of the box = L = 1 - 2x = 1 - 2(0.105662) m = 0.788676 m

Breadth of the box = B = 0.5 - 2x = 0.5 - 2(0.105662) m = 0.288676 m
