Whats 7xy+ x³-3y³-5x²y² in standard form?

Standard form of the polynomial is or .

Degree of the polynomial is 4.

Solution:

Given polynomial:

To write this polynomial in standard form:

Case 1:

Standard form of the polynomial is writing x from highest power to lowest power.

Therefore, standard form of the polynomial is

Case 2:

Standard form of the polynomial is writing y from highest power to lowest power.

Therefore, standard form of the polynomial is

Degree of the polynomial:

The highest power of in the polynomial is the degree of the polynomial.

Here, the highest power is 2 + 2 = 4.

Hence the degree of the polynomial is 4.

answer: x

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
