Given:
12 inches in 1 foot
number of inches in 2.5 feet
2.5 feet * 12 inches/1foot = 2.5 * 12 inches = 30 inches
1 foot + 1 foot + 0.5 foot = 2.5 feet
12 inches + 12 inches + 6 inches = 30 inches
12 inches : 1 foot = x : 2.5 feet
12 inches * 2.5 feet = x*1foot
30 inches * feet = x * foot
30 inches = x
        
             
        
        
        
Answer:
Step-by-step explanation:
hello :
the n-ieme term is : An=A1×r^(n-1)
A1 the first term       r : the common ratio
in this exercice : A1 =5       r = 125/-25=-25/5 = - 5         n = 9
A9=5×(-5)^(9-1) = 5×5^8 = 5^9     because :   ((-5)^(8)= 5^8)

The given graph shows the relationship between the social media posts and grade point average of different students in Brent's class. 
From the given graph, we can say that the grade point average of students decrease with increase in number of their social media posts.  
Since grade point average decreases approximately linearly with increase in use of social media posts, It is Strong negative correlation.
Hence, option D is correct i.e. Strong Negative Correlation.
