Answer 2

Answer:

21

Step-by-step explanation:

We are given that the mean of 13 ,15, 19 ,23, x and 29 is 20.

So, $Average = \frac{\text{Sum of all observations}}{\text{Total no. of observations}}$

$20 = \frac{13+15+19+23+x+29}{6}$

$20 \times 6 =13+15+19+23+x+29$

$120 =13+15+19+23+x+29$

$120 =99+x$

$120 -99=x$

$21=x$

Hence the value of x is 21
