For equations that model direct variation, they are of the form y = kx, where k is the constant of proportionality.
So, for there to be a constant of proportionality of 1/2, the equation should be y = 1/2 x.
This is the same as y = 3/6 x (since 1/2 = 3/6), so the answer is C.
Answer:
36¢ per pound
Step-by-step explanation:
In 1995, the price per pound was ...
($24.7 million)/(15 million lb) = $1.6467/lb
In 2000, the price per pound was ...
($31,297,583)/(15,616,728 lb) = $2.0041/lb
The difference was ...
$2.0041 -1.6467 = $0.3574 ≈ 36¢ . . . per pound
_____
In a calculation such as this, you want to keep enough significant digits so that you can appropriately round the final answer. Here, the result would be different if intermediate values were rounded to whole cents.
Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.
