Solve by multiplication method 30m + 44n = 1040m + 55n = 13♊♊♊♊♊♊♊♊♊♊♊ |
|
Answer» Answer: m = 1/5 , n = 1/11 Step-by-step explanation: (30M + 44n = 10)4 = 120m + 176n = 40 ----(1) (40m + 55n = 13)3 = 120m + 165n = 39 ----(2) (1)-(2) = 11n = 1 => n = 1/11 30m = 10-44×1/11 = 10-4 =6 m = 6/30 = 1/5 |

( 4.)Out of 10 students, who appeared in a test,three secured less than 30 marks and 3secured more than 75 marks. The markssecured by the remaining 4 students are 35,48, 66 and 40. Find the median score of thewhole group. |
|
Answer» There is a MISTAKE in this question. The total students are 10 but the marks are given only of 9 students. So, I am SOLVING this question assuming that the students are 9. Let the marks of those students who scored less than 35 marks be a, b, C and marks of the students who scored more than 70 marks be x, y, z. The ascending order of the marks = a, b, c, 39, 43, 51, x, y, z Now, Median = (n + 1)/2 = (9 + 1)/2 10/2 = 5 so, 5th OBSERVATION is 43. So, the median score of the whole group is 43 marks. |

Show that the points (4, 2,), (7, 5) and (9, 7) do not form a triangle |
|
Answer» Answer: Step-by-step EXPLANATION: Let A(4, 2), B(7,5) and C(9,7) be the given points......... By using Distance formula, AB = √[(7-4)2 + (5-2)2] => √[(3)2 + (3)2] => √(9 + 9) =>√18 => 3√2........... BC = √[(9-7)2 + (7-5)2] => √[(2)2 + (2)2] => √(4 + 4) => √8 => 2√2......... AC = √[(9-4)2 + (7-2)2] => √[(5)2 + (5)2] => √(25 + 25) => √50 => 5√2....... 3√2 + 2√2 = 5√2 AB + BC = AC. If any three points form a triangle, the sum of any two sides MUST be greater than the third side.... But here they are collinear points....... So, they dont form a triangle. Hence, proved! |
