Mmmmm....that's kind of a lot of stuff....

 

First one     ...    A) f(x) = 51.89x + 1137.5

 

Second ....   C) f(x) = 0.058x + 1.88; during the year 2020

 

Third  .....  C)  y = -292x + 2221; r = -0.98; predicted value at age 9  =  -292(9) + 2221  = -$407

 

Fourth...   B)  y = 2.8x + 15.1; r = 0.92;  2.8(8) + 15.1  = 37.5   (in 1000s)

 

Last One ... The approximate equation is

 

y = 12.7236x + 262.9

 

The budget will be   12.7 (11) + 262.9   = 402. 5

 

"A" seems closest
