Stella predicted that she would sell 56 sculptures. She actually sold 30 sculptures. What are the values of a and b in the table below? Round to the nearest tenth if necessary. Percent Error Item Approximate value Exact value Error Absolute error Ratio Percent error Sculptures 56 30 a b a = StartFraction 26 over 56 EndFraction; b = 46.4 percent a = StartFraction 30 over 56 EndFraction; b = 53.6 percent a = StartFraction 26 over 30 EndFraction; b = 86.7 percent a = StartFraction 26 over 26 EndFraction; b = 100 percent

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
