Answer 1

PROVIDED:-

• calculate the mean for the five even natural numbers.

ANSWER:-

$\huge{\bold\blue{⇝}}$ 6

$\color{pink}\bold\star\underline\mathcal{EXPLAINATION}\star$

${\bold\green{FORMULA:-}}$

mean = $\frac{Sum \: Of \: Observation}{Number \: Of \: Observation}$

• Five even natural numbers = 2, 4, 6, 8, 10.

• Sum of observation = 2+ 4+ 6+ 8+ 10 = 30

• Number of observation = 5

∴ Mean = $\frac{Sum \: Of \: Observation}{Number \: Of \: Observation}$

Mean = $\frac{30}{5}$

$\huge{\bold\blue{⇝}}$ Mean = 6

${\bold\blue{ADDITIONAL- INFORMATION}}$

ARITHMETIC MEAN:-

arithmetic mean of a group of observations is defined as,

mean = $\frac{Sum \: Of \: Observation}{Number \: Of \: Observation}$

And,

${\bold\green{FORMULA:-}}$ to find sum of observations if mean and number of observations are given.

Sum of observations = mean × no. of observations.

RANGE:-

the difference between the highest and the lowest observations is called the range of the given data or observations.

${\bold\green{FORMULA}}$ to find Range:-

Range = Highest value – lowest value.
