Select a setting so that each point will lie within the viewing window, (-11,5),(0,-4),(0,-7)
Ksivusya [100]

Answer:

Each given point will lie within the viewing window, Xmin=-12, Xmax=1, Xscl=1, Ymin=-8, Ymax=6, Yscl=1.

Step-by-step explanation:

The given points are (-11,5),(0,-4),(0,-7).

Here, the minimum values of x is -11 and maximum value of x is 0.

It means Xmin must be less than -11 and Xmax must be greater than 0.  

The minimum values of y is -7 and maximum value of y is 5.

It means Ymin must be less than -7 and Ymax must be greater than 5.  

Therefore, each given point will lie within the viewing window

Xmin=-12

Xmax=1

Xscl=1

Ymin=-8

Ymax=6

Yscl=1

vodomira [7]

Answer:

5/ 19 ≈ 0.26 = 26%

Step-by-step explanation:

given: student is female. there is a 100% chance that the student is female

probability we want = (favorable outcomes) / (total outcomes)

total outcomes = 19 because there are 19 female students and the student must be female

favorable outcomes = 19 - 14 = 5 females who do not have an A in the class

probability = 5/ 19 ≈ 0.26 = 26%

Tema [17]

Answer:

The answer to your question is 191

Step-by-step explanation:

Data

Total number of students = 464

Students in a band = 89

Students in sports = 215

Students in both activities = 31

Students do not practice any activity = ?

Process

1.- Subtract 31 from the students in a band and students in a sport

        89 - 31 = 58

       215 - 31 = 184

2.- Add the previous results anfd the number of students that practice both activities

         58 + 184 + 31 = 273

3.- Subtract 273 from the total number of students

         464 - 273 = 191

4.- Conclusion

191 students are not involved in any activity.

Barney is eight years older than Nemo. In seven years the sum of their ages will be 46. How old is Barney now?.
olga55 [171]
Let's represent Nemo's age with an n.

Barney is 8 years older so his age is nemo's plus 8. That is, Barney's age is n + 8

In seven years they will each be the age they are now plus 7. So, Nemo will be n + 7 and Barney will be n + 8 + 7. If the sum of their ages will be 46 we know that when we add these expressions we should get 46, so let's set the sum to 46 and solve for n.

n + 7 + n + 8 + 7 = 46
2n + 22 = 46
2n = 46 - 22
2n = 24
n = 12

That means that Nemo's age is 12.
Since Barney is 8 years older his age is 12 + 8 = 20.

To check our work we see that in 7 years Nemo will be 12 + 7 = 19 and Barney will be 20 + 7 = 27. Together that is 19 +27 = 46 as expected.
