Which polynomials are in standard form?
Pavlova-9 [17]

Answer:

3z - 1

-5p^{5} + 2p^{2} -3p + 1

Step-by-step explanation:

In a standard form of a polynomial, the value in the power of the variable reduces from left to right.

Therefore, 3z - 1 polynomial is in standard form since the z term comes to the left of the constant term.

Again, -5p^{5} + 2p^{2} -3p + 1 polynomial is also in standard form since the power of p reduces from left to right. (Answer)

A standard six-sided number cube is rolled. Find the probability of the given event. 1. an even number or a one
RSB [31]

1) probability of getting an even number or one: 2/3

2)probability of getting six or a number less than 3: 1/2

3)probability of getting even number or a number greater than five: 1/2

4)probability of getting an odd number or number divisible by 3: 2/3

Step-by-step explanation:

Sample space = {1,2,3,4,5,6}

Total number of possible outcome = 6

1) probability of getting an even number or one:

Sample space = {1,2,4,6}

P= 4/6

= 2/3

2) probability of getting six or a number less than 3:

Sample space = {1,2,6}

P= 3/6

= 1/2

3) probability of getting even number or a number greater than five:

Sample space= {2,4,6}

P= 3/6

= 1/2

4) probability of getting an odd number or number divisible by 3:

Sample space= {1,3,5,6}

P= 4/6

= 2/3
