Answer:
A. $66,000
Step-by-step explanation:
The relationship between sales data (in $1,000s) and advertising data (in $100s) is:
If if advertising is $3,000, then x =$30, and the point estimate for sales (in thousands of dollars) is:
Converting it to dollars, the point estimate for sales is:
Answer:
Between -2 and 0
Step-by-step explanation:
Step-by-step explanation:
AB = DC = 40 - 2x
AD = BC = 30 - 2x
there is not more explanation possible, I think.
we cut off from each side 2 pieces of x cm. so, AB, DC, AD, BC are the the remaining lengths.
the volume of the box is ground area times height (x is the length of the remaining flaps after the cut, so, when folding up these flaps/sides, they will be x cm high).
Volume = y = AB×AD×x
=> y = (40-2x)×(30-2x)×x = (1200 - 60x - 80x + 4x²)×x =
= (1200 - 140x + 4x²)×x = 4x³ - 140x² + 1200x
The answer will be 11.9988.
