Question

If the mean of 28, 34, 41, 23, 45, 18, 21 is 'X',
then the value of
2 - log 2 – log.,3 – log., 5 is​

Answer 1

Answer:

1

Step-by-step explanation:

Mean = 28 + 34 +41 +23 + 45 +18 + 21 /7

= 210/7 = 30

Therefore, 2 - logx 2 - logx 3 - logx 5

= 2 - logx (2×3×5)

= 2 - logx (30)

= 2 - log30 (30)

= 2 - 1 ( log30 (30) = 1 )

= 1
