Which polynomial is in standard form? 4xy+ 3x^3 5y - 2xy +4x^7y^92x+y^7+7y-8x²y^5– 12xy^25x^5 - 9x^2y^2 - 3xy^3 + 6y^57x^7y^2+5x^11y^5-3xy^2+2 asap plz

option 3 is the answer

Step-by-step explanation:

A polynomial  in two variables is said to be in standard form if exponent of one variable is keep decreasing  and another variable keep increasing

only option 3 follows it

As here exponent of x start from 5 and decreases up to 0

and exponent of y start from 0 and keep increasing up to 5

rest of the option do not follow this rule

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
