we know that
<u>The correlation coefficient</u> is a number between 
and 
that represent the linear dependence of two variables or sets of data
Using the function CORREL in a excel tool, calculate the correlation coefficient (r)
see the attached table
the correlation coefficient for the data in the table is equal to 
therefore
<u>the answer is</u>
Two trapezoid are similar
so it has some scale factor
look longer base of a big trap is 8 mi,and longer base of shorter trap is 4mi.
so that is half of big trapezoid.
so little trapezoid base should be 1 as big trap's shorter base is 2mi<span />
Answer:
the triangle is not right angled traingle
Step-by-step explanation:
For a right angle triangle
+ 
= 
where a is the base , b is the height and c is the hypotenuse
taking a= 6 b = 14 and c = 15
hence 
+
= 
36+196 = 232 which is not equal to 225
therefore the triangle is not right angled traingle
