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:

26

Step-by-step explanation:

28+34+41+23+45+18+21/7=196/7=26

Answer 2

Answer:

The required answer is $1$.

Step-by-step explanation:

Concept:

In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. The average of the provided observations is the mean of a set of observations. We divide the sum of the observations by the total number of observations to determine the mean.

Given:

The mean of counts $28, 34, 41, 23, 45, 18, 21 = x$

To find:

We have to find the value of $&2-\log _{x}^{2}-\log _{x}^{3}-\log _{x}^{5}$.

Solution:

The value of $x$ is,

Apply mean formula,

$&x=\frac{28+34+41+23+45+18+21}{7}\\=\frac{210}{7}\\=30 \\&2-\log _{x}^{2}-\log _{x}^{3}-\log _{x}^{5}=2-\log _{x}(30) \\2-\log _{30}^{30}=2-1\\=1$

Hence, the required value is $1$.
