FAQs

What is the formula P 2W 2L? ›

The perimeter of a square field is given by the equation P = 2l + 2w, where P represents the perimeter, l represents the length of the field, and w represents the width of the field.

Expert-Verified Answer

The given equation p = 2l + 2w represents the perimeter of a rectangle where p is the perimeter, l is the length, and w is the width. To find an equivalent equation, we can simplify it by dividing both sides by 2. This gives us the equivalent equation p/2 = l + w.

Answer and Explanation:

Solving P = 2L + 2W for L gives L = P − 2 W 2 . In general, to solve an equation for a variable, we can use the following rules to manipulate the equation without changing its truth value. We can add or subtract the same number or term from both sides.

The equation P=2(L+W) gives the perimeter P of a rectangle, where L is the length and W is the width.

The P-value formula is short for probability value. P-value defines the probability of getting a result that is either the same or more extreme than the other actual observations. The P-value represents the probability of occurrence of the given event.

Profit and Loss Formulas

The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.

In mathematics, the perimeter of a rectangle is the distance around the rectangle. If we know that a rectangle has a length of l units and a width of w units, then we can find the perimeter, P, of the rectangle using the formula P = 2 l + 2 w .

To write equation of a line in two-point form, simply substitute the coordinates of the given two points in the equation ( y − y 2 ) = y 2 − y 1 x 2 − x 1 ( x − x 2 ) . Example: Find the equation of a line passing through the points and . Substitute the values in ( y − y 2 ) = y 2 − y 1 x 2 − x 1 ( x − x 2 ) .

P = power W = work ∆t = elapsed time Power is the amount of work done per unit time (i.e., power is the rate at which work is done).

The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). The p-value for: a lower-tailed test is specified by: p-value = P(TS ts | H ₀ is true) = cdf(ts)

What is variable formula? ›

A variable is a quantity that may be changed according to the mathematical problem. The generic letters which are used in many algebraic expressions and equations are x, y, z. In other words, a variable is a symbol for a number where the value is not known. For example, x + 5 = 10. Here “x” is a variable.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

Answer and Explanation:

P = 2 w + 2 l.

To calculate the length and width of a rectangle first, calculate the value of width 'w' by using the area of rectangle formula that is, 'w = A/l'. Then substitute the value of width in the formula of the perimeter of a rectangle and simplify the value of length 'l', that is, P = 2 (l + A/I).

P-value means probability value, which tells you the probability of achieving the result under a certain hypothesis. Since it is a probability, its value ranges between 0 and 1, and it cannot exceed 1.

P = power W = work ∆t = elapsed time Power is the amount of work done per unit time (i.e., power is the rate at which work is done).

Pythagorean theorem formula is: a² + b² = c² , where “a” and “b” represent the lengths of the two shorter sides of the right triangle and “c” represents the “hypotenuse.”

The Energy expended to do work in unit time is termed as Power. It is represented as P. Power Formula is articulated as, P = E t. P = W t.

The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test). The p-value for: a lower-tailed test is specified by: p-value = P(TS ts | H ₀ is true) = cdf(ts)
