Answer 1

⚘GIVEN:

• Scores : 35,30,45,60,63,55
• no. of innings = 6

⚘FIND:

• Mean scores = ?

⚘SOLUTION:

we know, that

$\bold{mean = \frac{ ∑_x }{n} }$

where,

• $\bold{∑_x}$ = sum of all scores
• n = Total no. of innings

put these values in formula if mean we got

$\bold{ \to mean = \frac{ ∑_x }{n} }$

$\bold{ \to mean = \frac{ 35 + 30 + 45 + 60 + 63 + 55}{6} }$

$\bold{ \to mean = \frac{ 288}{6} }$

$\bold{ \to mean = \frac{ \cancel{ 288}}{ \cancel6} }$

$\bold{ \to mean = 48 }$

Hence, mean score is 48.
