Question

are
1. The weights of some people of a colony
45 kg, 25 kg, 82 kg, 35 kg, 55 kg,
60 kg, 32 kg, 37 kg, 80 kg and 21 kg.

these weights.​

Answer 1

$\huge\mathcal\colorbox{golden}{{\color{black}{★ANSWER★}}}$

GIVEN ÷

WEIGHT OF STUDENTS ARE

45,25,82,35,55,60,32,37,80,21

${\huge{\rm{\underbrace{Explanation\checkmark}}}}$

ARITHMETIC MEANS=TOTAl SUM OF NO.÷TOTAL NO.OF STUDENTS

=45+25+82+35+55+60+32+37+80+21/10

=472/10

=47.2

SO, ARITHMETIC IS 47.2

RANGE IS THE HIGHEST NO.-SMALLEST NO.

SO HIGHEST NO.IS=82

SMALLEST NO.=82-21

=61

SO,RANGE IS. 61

Answer 2

GIVEN =

WEIGHT OF STUDENTS ARE

45,25,82,35,55,60,32,37,80,21

ARITHMETIC MEANS=TOTAl SUM OF NO.÷TOTAL NO.OF STUDENTS

=45+25+82+35+55+60+32+37+80+21/10

=472/10

=47.2

SO, ARITHMETIC IS 47.2

RANGE IS THE HIGHEST NO.-SMALLEST NO.

SO HIGHEST NO.IS=82

SMALLEST NO.=82-21

=61

SO,RANGE IS. 61
