Answer:
Option A
Step-by-step explanation:
Given that A linear model is given for the data in the table: y=1.25x+2.
Let us write observed values for each x and also the predicted values as per equation.
x            2     3        4      8    10      16    20    24    Total
y((O)      3      4        7     12   16      22   28    30
y(P)     4.5   5.75      7     12   14.5   22   27    32
DEv    1.5    1.75      0       0     1.5     0      1       2     7 75
where y(0) represents observed y or y in the table given
y(P) gives values of y predicted as per the equation 1.25x+2
Dev represents the absolute difference
Hence answer is option 
A.7.75
 
        
             
        
        
        
Answer:
Step-by-step explanation:

Answer:
37
Step-by-step explanation:
f(x)=2x²−x+9
f(4)= 2(4)²-4+9
= 32-4+9
= 37
