What is the coefficient of x^2y^3 in the expansion of (2x+y)^5

Answers

Answer:

Step-by-step explanation:

A P E X

We figure out the coefficient of x^2y^3 by figuring out the coefficients in both (x+y)^4 and (x+2y)^4.

Using the binomial theorem, the coefficient of x^2y^3 on the first expansion is

(4 choose 3)x^2y^3=6x^2y^3,

and the coefficient of x^2y^3 on the second expansion is

(4 choose 3)x^2(2y)^3=6x^2(4y^2)=24x^2y^3.

Thus, the coefficient in the sum of these two expansions is 6+24=30.

The sum of two numbers is 50. the greater number is four less than five times the lesser number. Find the numbers

Answers

The required two numbers are 9 and 41.

What is the equation?

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

Let x be the lesser number, and y be the greater number.

From the question, we know that:

x + y = 50 (Equation 1: The sum of the two numbers is 50)

y = 5x - 4 (Equation 2: The greater number is four less than five times the lesser number.)

The equation is to solve for one of the variables, and then substitute that value into the other equation to find the other variable.

Then, two numbers are x = 9 and y = 41.

What is the correlation coefficient of y=0.48x+75.2

Answers

a correlation coefficient shows how linear a set of data is, so for any points that comply with the given equation, the correlation coefficient will be one, that is, the correlation is completely linear, because the given equation is alinear one, there is a linear correlation of x and y. Indeed, the equation is a line equation in general form.
