Question

63,66,69,x,x+2,76,89,103 The following data is arranged in ascending order of magnitude. If the median is 71 find x

Answer 1

Answer:

70

Step-by-step explanation:

the total number of terms in the given data is 8.

since it is even

the median can be calculated by adding the middle two numbers and dividing by 2.

so,

${x + (x + 2)} \div 2 = 71 \\ 2x + 2 = 142 \\ 2x = 140 \\ x = 70$

Answer 2

Answer:

the total number of terms in the given data is 8.

since it is even

the median can be calculated by adding the middle two numbers and dividing by 2.

so,

\begin{gathered}{x + (x + 2)} \div 2 = 71 \\ 2x + 2 = 142 \\ 2x = 140 \\ x = 70\end{gathered}

x+(x+2)÷2=71

2x+2=142

2x=140

x=70
