Answer:
Step-by-step explanation:
hey there!!!
we know already that the area of a triangle is given as
where b= base
and h= heigth
Given that the height is 5 times more than twice it base
let h= 2b+5
Now we substitute h=2b+5 in the area of the triangle
=3.1*10^3
=3.1*10*10*10
=3.1*1000
=3100
<u>Answer- </u>D. There is a strong negative association between the variables
<u>Solution-</u>
Properties of Correlation Coefficient
1- Its value ranges between -1 and 1.
2- The greater the absolute value of correlation coefficient, the stronger is the linear relationship.
3- The weakest linear relationship is indicated by a correlation coefficient equal to 0.
4- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
5- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
As the given correlation coefficient is -0.98 (-ve), whose absolute value is 0.98 (closer to 1)
So there is a strong negative association between the variables.
