Question

The teacher measured the length of each rope that the student submitted, they are 2 ft, 1.8 ft, 1.75, 2 ft, 1.5 ft and 2 ft. What will be the average length of all the ropes

Answer 1

Step-by-step explanation:

$Average = \frac{ sum \: of \: all \: Obsrvations}{ number \: of \: observations }$

$average = \frac{2 + 1.8 + 1.75 + 2 + 1.5 + 2}{6} \\ = \frac{11.05}{6} = 1.84166 = 1.842ft.$

Answer 2

Answer:

The average length of all ropes is 1.841ft

Step-by-step explanation:

The given lengths of ropes submitted to the teacher by the students are 2ft,1.8ft,1

.75ft,2ft,1.5ft and 2ft respectively.

To find the average length of ropes,we use the relation as given below

$Average=\frac{Sum\:of \: observations}{No.\:of \: observations}$

Here No.of observations=6

And the sum of observations is

$2 + 1.8 + 1.75 + 2 + 1.5 + 2 \\ = 11.05$

Hence,substituting these values in the above relation,we get the average as

$average = \frac{11.05}{6} = 1.841 \: ft$

Therefore,The average length of all ropes is 1.841ft
