Question

if the mean of the data 6,8,10,3,7 and m is 7, then find the value of m.​

Answer 1

Answer:

8  PLEASE MARK ME THE  BRAINLIEST.

Step-by-step explanation:

Mean = sum of observations/frequency

6+8+10+3+7+m /6= 7

34+m/6 =7

34+m = 42

m=8

Answer 2

$\huge\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{...}}$

$\longrightarrow \boxed{\sf Mean = \frac{sum \: of \: number}{total \: number}} \\ \\\longrightarrow \sf 7 = \frac{6 + 8 + 10 + 3 + 7 + m}{6} \\ \\\longrightarrow \sf 7 \times 6 = 34 +m \\ \\\longrightarrow \sf m = 42 - 34 \\ \\ \longrightarrow \boxed{\sf m = 8}$
