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:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours
