What is the sst for the data set (1,5), (2,9), (4,10)

14

Step-by-step explanation:

SST = ∑ ( y − ȳ ) ² (ȳ = pronounced y bar is the mean of y values)

ȳ = (5+9+10)/3 = 24/3 = 8

∑ ( y − ȳ ) ² =  ( 5 − 8 ) ² +  ( 9 − 8 ) ² +  ( 10 − 8 ) ²

=  (  − 3 ) ² +  (  1 ) ² +  ( 2 ) ²

= 9 + 1 + 4

= 14

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
