The correlation coefficient is calculated by the given formula
Here we have to find correlation coefficient for three ordered pairs, so n=3
Substituting all the values in the above formula,
r= -0.24
(9x8) divided (2+10)
72 divided 12
=6
1 5/6 + 1/2
= 11/6 + 3/6
= 14/6 answer
Volume of water
=6600 l=6600×0.001m³=6.6m³
▶Considering only inner volume
Let,
x↪ thickness of bottom of cuboid
Then,
↪h=3.5-x
{to get inner height of cuboid}
↪ b=1.2m-2×10cm=1.2m-0.2m=1m
{to get inner breadth of cuboid we must subtract it from 2×thickness of wall }
↪ l=2.4m-2×10cm=2.4m-0.2m=2.2m
{to get inner length of cuboid we must subtract it from 2×thickness of wall }
❇Since
↪inner volume=volume of water
↪ l×b×h=6.6
↪ 2.2×1×(3.5-x)=6.6
↪ 3.5-x=6.6/2.2
↪ x=3.5-3
↪ x=0.5m➡required thickness
There are many different arrangements of data that include rows and columns. I've listed some below:
-Table
-Matrix
-Array
Hope this helps!! :)
