Answer:

I disagree.

Step-by-step explanation:

An integer is a whole number ranging from -2,147,483,648 to 2,147,483,647.

A ratio of two integers with -4 could be -4/1, so -4 is a rational number.

<h3>Answer:</h3>

I agree.

<h3>Solution:</h3>

Every single integer can be written as a fraction.
Please remember that the set of integers includes negative numbers, zero, and positive numbers.
In this case, we have a negative number (the minus sign in front of the number tells us it is negative).
So, how can we write an integer as a fraction?
Every integer can be written as a fraction with a denominator of 1.
Therefore, the answer is:
-4/1
So, is 4 rational? Yes, because it can be written as a fraction.

Hope it helps.

Answer:

Step-by-step explanation:

From the given question,

a). m∠WAX = 60°

If m(arc WX) = 100°

Then by theorem,

Angle formed between the chords in a circle, measures the half of the sum of intercepted arcs.

m(∠WAX) = $\frac{1}{2}(\text{arc WX + arcYZ})$

60° = $\frac{1}{2}(100+\text{arcYZ})$

120 = 100 + arc YZ

120 - 100 = arc YZ

m(arc YZ) = 20°

b). m(arc WX + arc YZ) = 2(60°)

m(arc WX + arc YZ) = 120°

Answer:

arc AB = 3.14 in

Step-by-step explanation:

circumference of full circle = π2r = (3.14)(2)(6) = 37.68 in

arc AB = (30°/360°)(37.68) = 3.14 in

2. A teacher asked his class of 20 students, "What is your age? Their responses are shown in the dot plot below.

Karolina [17]

Answer:

Yes, average does represent the centre of this data.

Average = 15.9

Step-by-step explanation:

As this question is not complete and not correctly written. Let's try to find an answer for this question.

Total number of Students = 20 = n

and we are given this data:

14, 15, 17, 18, 16.

which is just five entries and total number of students are 20. 15 entries are missing in this questions. So, let's add our own values into this question.

New set of entries for 20 students.

1. 14

2. 15

3. 17

4. 18

5. 16

6. 19

7. 17

8. 16

9. 17

10. 17

11. 15

12. 20

13. 14

14. 17

15. 18

16. 19

17. 13

18. 20

19. 17

20. 16

So, let's calculate the average of these numbers.

Average = Sum of all entries/ Total number of entries.

Average = 318/20

Average = 15.9

So, the average age of all the students of class is 15.9.

Let's calculate median:

For median , data must be arranged in a order from least to greatest number. Median is a number from that data which is at half way. In case of odd numbers, it is easy to identify median because there is only one number. and in case of even numbers, median is the average of the two middle numbers. So, here we have even numbers and median is the average of two middle numbers = 17 + 17/2 = 17

Median = 17

Yes, average does represent the centre of this data.
