Question

The mean of 1,3,5,7,9,x is 5 calculate the value of x

Answer 1

$\underline{\large\bf{\mathfrak{Hello!}}}$

$Mean \: of \: 1,3,5,7,9,x \: is \: 5. \\ \\ mean = \frac{sum \: of \: all \: the \: numbers}{total \: number} \\ \\ 5 = \frac{1 + 3 + 5 + 7 + 9 + x}{6} \\ \\ = > 1 + 3 + 5 + 7 + 9 + x = 30 \\ \\ = > 25 + x = 30 \\ \\ = > x = 30 - 25 \\ \\ = > x = 5$

$\boxed{ x = 5}$

Answer 2

Answer:

Step-by-step explanation:

Mean = sum of observation/No. of observation

Mean = 3+5+7+9+x/5

5 = 24+x/5

5*5 = 24+x

25 = 24+x

x = 25-24

x = 1
