Options :
(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x
Answer:
C.) ŷ = 2.79X + 55.8
Step-by-step explanation:
Given the data:
cost (x): 9 2 3 4 2 5 9 10
Number of products sold: 85 52 55 68 57 86 83 73
Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below
ŷ = 2.79X + 55.8
With y being the predicted or dependent variable
Slope or gradient of the line = 2.79
X = the independent variable
55.8 = the intercept.
Answer:
Thus, a product that normally costs $4 with a 70 percent discount will cost you $1.20, and you saved $2.80. You can also calculate how much you save by simply moving the period in 70.00 percent two spaces to the left, and then multiply the result by $4 as follows: $4 x . 70 = $2.80 savings.
