Answer:
Given in the information set as
26, 34, 38, 49, 65, 76, 81
Sum = 369
No of entries = 7
Mean =52.71
When 1213 is included
New sum = 1582
No of entries =8
The new mean will be 197.75
Thus mean will be increased by 145.04
Answer:
1st angle = 30
2nd angle = 60
3rd angle = 90
Step-by-step explanation:
- let ,1st angle be x , 2nd angle be 2x and 3rd angle be 3x
- x+2x +3x =180
- 6X =180
- x =180/6
- x =30
For example, y = k/x; when x = 3 => k = 3y; when y = 9 => k = 27 and x = 27/9 = 3;
The answer is 3!
Cross multiply 3x-5 with 4 and 4x + 1 with 2
Which it would give you 12x-20=8x+2 then solve for x
