A 5. The scores on a recent statistics test are given below. Does this table describe a relative
frequency distribution? Why or why not?

C

Step-by-step explanation:

The scores in a recent statistics test are given in the frequency distribution below.

\begin[gathered]Vefti\begin[array]

[clcc)$Scores&$Frequency\\-&-10-60&4\\61

70&101171-808 121181-90841191-10&5\\&

\\$Total&35\end{array\rightend gathered]

The relative frequency is calculated in the table below.

\begin[gathered) Meft\begin[array] [clclc]$Scores&$Frequency&$Relative Frequency\l—-&-&V0-6084&\dfrac{4) (35)\times 100-14.29%&-&--

(35)\times 100 11.43\% 61-70&10&\dfrac{10]

{35}\times 100=28.5771-808 12&\cifrac{12} (35)\times 190–34 29 %) 81-9084&\dfrag|4)

(35)\times 100=1143 %||| |91-1085&\dfrac|5)

$Total&35&100\end(array) right/end[gathered]

Therefore, the relative frequency table is that in Option C.

1. 3.4/4

2. 0.8/7

3. 0.5 x 3

4. 0.9 x 6

5. 10.8

6. 2.35

7. 0.567

8. 9.35

9. 0.02

10. 0.06

11. 0.16

12. 0.42

13. 0.63

14. 5.6

15. 8.1

16. 9.9

17. 0.28

18. 0.48

20. 0.49

21. 0.45

22. 0.72

23. 0.9

24. 0.88

25. 0.75

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
