Answer:
$0.067
Step-by-step explanation:
Total cost of 16 bags = $12.80
weight in 1 bag = 12 ounce
weight in 16 bag = 16 * weight in 1 bag
weight in 16 bag = 16* 12 ounce = 192 ounce
Thus,
192 ounce cost = Total cost of 16 bags= $12.80
cost of 182 ounce = $12.80
to find cost of 1 ounce , we divide both side by 182
cost of 1 ounce = 12.80/192 = $0.067
Thus,
the unit cost per ounce is $0.067
Answer:
ŷ = -0.18363X + 19.71681
-0.9685
Step-by-step explanation:
Given the data:
Mileage, x: 22 14 18 30 8 24
Price, y: 16 17 17 14 18 15
Using the online regression calculator :
The regression equation obtained is :
ŷ = -0.18363X + 19.71681
Where ;
y = predicted variable
- 0.18363 = slope or gradient
X = predictor variable
19.71681 = intercept
The correlation Coefficient R = -0.9685
This signifies a strong negative relationship between the x and y variable.
