A school principal has to choose randomly among the six best students in each grade to be the school captain every month. For that purpose, she assigned each student a number. Then she rolled two dice numbered from 1 to 6 three times and selected the student whose number was repeated most often.

Which of the following best describes the method used by the principal?

It's an unfair method because each student will not post the same outcomes.
It's a fair method because each result is an equally likely possible outcome.
It's a fair method because it's a limited number of students.
It's an unfair method because two or more students could get the same results.

Step-by-step explanation: hope this helps

Answer 2

Answer:

B. It's a fair method because each result is an equally likely possible outcome.

Step-by-step-explanation :

According to the question , there are a total of 6 students to be selected by the principal.  

So, the principal chose to roll two dice numbered 1, 2, 3, 4, 5, 6 for the selected students and choose the one whose number is most repeated.

Since we have sis sides on a dice , 2 dice [tex]= 6\times6=36[/tex]

The  probability that a student will choose one number :[tex]\frac{1}{36}[/tex]

Thus, the selection of each student is given by the number

[tex]\frac{1}{36}[/tex]

So,each result is an equally likely possible outcome.

So, the principal choose a fair method.

Find all solutions to the equation $x^2 - 8x = -16$.

Answers

Answer:

x = 4

Step-by-step explanation:

x^2 - 8x = -16

Add 16 to both sides.

x^2  8x + 16 = 0

This may be the square of a binomial.

x^2 is the square of x

16 is the square of 4 and -4.

Let's check the middle term:

2ab = 2(x)(-4) = -8x

Yes, it is the square of a binomial.

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x - 4 = 0 or x - 4 = 0

x = 4 or x = 4

Answer: x = 4

She didnt mind cleaning, generally, but today she felt even more driven to scrub, sweep, and vacuum away the cloud of hurt feelings that seemed to have engulfed her. Her two older sisters Sadie and Rebecca, had barely helped clear the breakfast dishes before scrambling to get out the front door and taking off for the beach in Sadies car. 2 Annie understood why her older sisters left to hang out with kids their own age, singing along to the radio as they pulled out of the driveway, but it still stung a little. Today, though, Annie was especially frustrated because it was the first Saturday of the summerthe day they typically spent with Mom to celebrate another year of her teaching. Whats more, yesterday marked the end of Moms twentieth year as a teacher. While Annie had looked forward to celebrating together, Sadie and Rebecca had rushed off with their friends, but not before presenting gifts that made Annies seem childish. How does the authors choice to show Annies point of view affect the meaning of the excerpt? Select two options. by elaborating on why Annie dislikes the gift she chose by illustrating how inferior Annie feels to her two sisters by exhibiting how Annie did not plan ahead as her sisters had done by presenting Annies bitterness over how this day is being recognized by commenting on why Annie chose to clean the house instead of buying a gift PLEASE HELLPPP!!!!
