Question

Marcus bought pumpkins that weigh 8 lb, 11 lb, 23 lb, and 15 lb. What is the mean weight of his pumpkins? Round to the nearest tenth if needed.

Answer 1

The mean is the average of the numbers

to  found  the mean  of n  articles  we  add  the  values  of  all the articles   and divide it by  the number of articles .

Here we are given  Articles as  pumpkins

The value of an  article is it's  weight

the number of Articles  = number of pumpkins = 4

Let us start finding mean  of the weight of the pumpkins

(8   +   11  +  23   + 15  ) divide by 4

( 57 ) divide by  4  = 14.25  

To round to  nearest tenth first we make it :  14.3    ( 5 was >=5 ) so we removed  5 and add 1 in 2

Now it is  14    ( because  3 is  <  5  so we removed it without  any change in the digit left to it )

Now it is 10 ( as 4 is also <5 so we remove  it without any change inthe digit left to it )

Answer : 10
