Answer: The correct options are
(d) 720.
(a) 336.
(c) 132.
(a) 5040.
Step-by-step explanation: The calculations are as follows:
(1) The number of ways in which six books be arranged on one shelf is given by
So, the total number of ways is 720.
Option (d) is CORRECT.
(2) Given that there are 8 girls competing in an ice-skating competition.
So, the number of ways in which they can finish in first, second, and third place is given by
Thus, the total number of ways is 336.
Option (a) is CORRECT.
(3) The number of ways in which a president and vice president can be selected from a class of 12 is given by
Thus, the total number of ways is 132.
Option (c) is CORRECT.
(4) The number of ways in which 7 students can line up for a class picture is given by
Thus, the required number of ways is 5040.
Option (a) is CORRECT.
Answer:
Both the students were correct.
Step-by-step explanation:
Given : The polynomial is -
To find : Who correctly grouped the terms to factor.
Lucas group the polynomial -
Now, we solve the Lucas polynomial
Erick group the polynomial -
Now, we solve the Erick polynomial
The factors of Lucas and Erick are same.
Each grouping leads to the same result.
Therefore, Both students are correct.
Answer:
Sample Response: Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.
What did you include in your response? Check all that apply.
Polynomials can be grouped differently to factor.
Each way results in common binomials.
Each can be factored as a product of prime polynomials.
Step-by-step explanation:
is it rational or irrational
