d. 80 g, 28 g, 110 g, 84 g

Answer 1

Answer:

a. 7,9,5,3,1    average = 5

b. 33,12,0,50,34,15 average 24  

c. 42 cm,17 cm, 44 cm, 32 cm, 30  cm average  33

d. 80 g, 28 g, 110 g, 84 g   average  75.5

Step-by-step explanation:

Finding average of the given data

             average  = sum of elements ÷ number of elements

  a) 7, 9, 5, 3, 1

           $\frac{7+ 9+5+3+1}{5}$ =  $\frac{25}{5}$ = 5

  b) 33, 12, 0, 50, 34, 15

           $\frac{33+12+0+50+34+15}{6}$  =$\frac{144}{6}$ =24

  c)  42 cm,17 cm,44 cm,32 cm,30 cm

                  $\frac{42+ 17+ 44+32+30}{5}$ = 33

  d) 80 g, 28 g, 110 g, 84 g

                    $\frac{80 + 28+110+84}{4}$ = 75.5
