Question

find the mean of 2.4,4.5,5.2,7.1,9.3​

Answer 1

Answer:

Give

the numbers are 2.4,4.5,5.2,7.1 and 9.3

The mean can be calculated as below

Mean = Sum of numbers / Number of numbers

= (2.4+4.5+5.2+7.1+9.3)/5

we get,

= 28.5/5

=5.7

Answer 2

Answer:

4.2

Step-by-step explanation:

the above series is an individual series i.e. (X)

hence we have to find out direct arithmetic mean.

first - (add all the numbers in the series )

i.e 2+4+4+5+5+2+7+1+9+3 = 42 (sum total of X)

then do simple average ,

therefore = sum total of X/ n

{ here 'n' is the number of items , which is 10 in this question}

so, by the above formula - 42/10 = 4.2 as your mean
