If both variables tend to deviate in the same direction (both go above their means or below their means at the same time), then the covariance will be positive.

What Is Covariance?

The direction of the link between the returns on two assets is measured by covariance. Asset returns move together when the covariance is positive, and inversely when the covariance is negative.

It is calculated by analyzing at-return surprises (standard deviations from the expected return) or multiplying the correlation between the two random variables by the standard deviation of each variable.

Types of Covariance:-

This link is determined by a covariance value, either positive or negative.

Covariance Calculated:-

Covariance = Σ[tex][ ( Return_{abc} - Average_{abc} ) * ( Return_{abc} - Average_{abc} ) ][/tex]÷ [ Sample Size - 1 ].

Therefore, the both variables tend to deviate in the same direction, then the covariance will be positive.

One definition of a parabola includes a line and a point (the focus) (the directrix). The directrix is not the main focus. The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.

Given a horizontal parabola centered on the origin opens to the left,

The probability of all 6 locations being in water is 0.9994.

The probability of a single location being in water is 0.71. When finding the probability of 6 locations all being in water, we can use the binomial probability formula:

where n is the number of trials, x is the number of successes, p is the probability of success, and q is the probability of failure.

Plugging in the values, we get:

P(x=6) = (6!/(6!(6-6)!)(0.71^6)(0.29^(6-6))

Step-by-step explanation:

The dimensions of the paint, obtained by factoring the polynomial function for the area of the tray, 42·x + 135·x + 108 are as follows;

(a) The width of the tray = 6·x + 9

(b) Area of the square paint compartment is 9 in²

(c) The width of the edges is 12 inches

The factors of a polynomial are other polynomials of lesser degree, that when multiplied together, produces the polynomial which is factored.

The area of the paint tray = 42·x² + 135·x + 108 in²

The dimensions of the square paint compartment are the same

Space along the edge of the tray = 2 × space between the squares

(a) The length of the tray obtained from the diagram in the question = 7·x + 12 inches

Using an online tool, we get;

42·x² + 135·x + 108 = 3·(2·x + 3)·(7·x + 12)

The area of a rectangle = Length × Width

Therefore, the width of the tray = The area ÷ The length

Width = (42·x² + 135·x + 108)/(7·x + 12) = 3·(2·x + 3)

(b) Let s represent the side length of each square paint compartment, we get;

Width of four compartments + 3 spaces between compartments = (7·x + 12) - 2 × 2·x

Width of four compartments + 3 spaces between compartments = 4·s + 3·x

4·s + 3·x = (7·x + 12) - 2 × 2·x = 3·x + 12

4·s = 3·x + 12 - 3·x = 12

s = 12/4 = 3

s = 3

The side length of each square = 3 inches

The area of each square paint compartment = s²

s² = 3² = 9

(c) Where the width = 45 inches, we get;

3·(2·x + 3) = 45

2·x + 3 = 45/3 = 15

2·x + 3 = 15

2·x = 15 - 3 = 12

x = 12/2 = 6

x = 6

An equation is a mathematical statement that asserts the equality of two expressions. It typically consists of two parts, separated by an equals sign (=). For example, the equation 2x + 3 = 7 is a statement that the expression 2x + 3 is equal to the expression 7. The expressions on either side of the equals sign are often referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation. Equations can be used to model and describe a wide range of real-world situations, including physical phenomena, financial models, and scientific relationships. Equations can be simple or complex, involving one or more variables and a variety of mathematical operations. Equations can be solved to find the value of the variable(s) that make the equation true.
