Answer 2

Answer:The value of x is 1.6.

Step-by-step explanation:

Given:The numbers 2 , 3 , 5 and x have an average mean equal to 4.

To find:We have to find the value of x.

Explanation:

Step 1:We know the formula for calculating mean can be given by,

        Mean(M) = Sum of observations/Total number of observations

Step 2:It is given that the numbers 2 , 3 , 5 and x have an average mean equal to 4.

Step 3: Substituting the value on mean formula we get,

⇒                     $4 = \frac{(2 + 3 + 5 + x) }{4}$

⇒               $4$ × $4 = 10x$

⇒                   $16 = 10x$

⇒                   $\frac{16}{10} = x$

⇒                  $1.6 = x$

∴ The value of x is 1.6.

Definition of Mean:Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Mean = (Sum of all the observations/Total number of observations)

Mean Formula:The basic formula to calculate the mean is calculated based on the given data set. Each term in the data set is considered while evaluating the mean. The formula for mean is given by the ratio of the sum of all the observations and the total number of observations. Hence, we can say;

Mean = Sum of the Given Observations/Total number of Observations

To calculate the arithmetic mean of a set of observations we must first add up (sum) all of the data values (x) and then divide the result by the number of values (n). Since ∑ is the symbol used to indicate that values are to be summed (see Sigma Notation) we obtain the following formula for the mean (x̄):

⇒                      x̄=∑ x/n
