In a statistical data, the difference between mode and mean is k times the difference between median and mean, then what is the value of k?

Correct Answer - 4.25

Correct Answer - माध्य = 39 , बहुलक = 15 , माध्यक = 15 , नहीं

Correct Answer - बहुलक = 14, माध्यक = 14

Correct Answer - (i) 0.28 (ii) 0.4 (iii) 0.32

3 median =2mean + mode 3(33) = 2(27) + mode 99 = 54 + mode Mode = 99 - 54 Mode =45 [ option C ]

Given that \(\vec a, \vec b\) and \(\vec c\)are unit vectors. i.e., |\(\vec a\)| = |\(\vec b\)|  = |\(\vec c\)| = 1 And \(\vec a\) + \(\vec b\) + \(\vec c\) = \(\vec 0\) Then \((\vec a+\vec b+\vec c).(\vec a+\vec b+\vec c)=\vec 0.\vec...

Correct option is (C) 10 Number of observations is n = 6 (even) \(\therefore\) Median = Average of \(\frac n2th\) observation and \((\frac n2+1)^{th}\) observation \(=\frac{9+x}2\) \(\therefore\) \(\frac{9+x}2\) = 9.5    \((\because\) Median = 9.5 (given)) \(\Rightarrow\) 9+x = 9.5 \(\times\) 2 = 19 \(\Rightarrow\) x = 19 -...

Correct option is (B) 26 Observations after multiplied by 2 are 10, 12, 16, 20, 24, 28, 28, 30, 32, 40 Median \(=\frac12(5^{th}+6^{th})\) observations \(=\frac12(24+28)\) = 26 \(\therefore\) Median of new data is 26.

Correct answer is (ii) Median
