Answer:
Hi
Explanation:
2ab∛(4³*3ab²)-5∛(3³*3)
=8ab∛(3ab²)-15∛(3)
=8ab∛(3ab²)-15∛(3a³ab³b²)
=8ab∛(3ab²)-15ab∛(3ab²)
=-7ab∛(3ab²).
Answer:
(a) 31 , 54
(b) 48
Explanation:
- Data set : 13 13 13 20 26 29 31 33 34 34 35 35 36 37 38 41 41 41 45 45 47 47 48 52 54 56 56 62 67 82
- Part a requires you to find second decile and 8th decile
- For second decile there are 30 elements for second decile:
(a) Locator: 0.2*30 = 6
Round up to 7
20% decile = 31
Locator: 0.8*30 = 24
Round up to 25
80% decile = 54
(b) To determine 67th percentile
Locator : 0.67^30 = 20.1
Round up to 22
67% percentile = 48
What’s the question though
