Simonne predicted that she would sell 99 picture frames. She actually sold 88 picture frames. 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 Picture frames 99 88 a b b a = StartFraction 11 over 99 EndFraction; b = 11.1 percent a = StartFraction 11 over 88 EndFraction; b = 12.5 percent a = StartFraction 88 over 99 EndFraction; b = 88.9 percent a = StartFraction 11 over 11 EndFraction; b = 100 percent

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
