Question

The mean of 1,2,x,3 and 4 is 2. Calculate the value of x

Answer 1

Answer:

0

Step-by-step explanation:

we know that

sum of observation / number of observation = mean

therefore

\begin{gathered} \frac{1 + 2 + x + 3 + 4}{5} = 2 \\ 10 + x = 10 \\ x = 0\end{gathered}51+2+x+3+4=210+x=10x=0

Answer 2

Step-by-step explanation:

mean = 1+2+×+3+4/ 2

2= 10 +x /2

2×2 = 10+ x

4 -10 = x

x= -6
