Solution :
a). The required linear regression model is
Price = 
b). The
for the variable "Age of part" is 0.0000
Since the
is less than 0.05, so it is significant to the model.
The p-value for the variable "Number of bidders" is 0.1940
Since
is not less than
, so it is significant to the model.
c). We cannot say that model is significant because variable " the number of bidders" is not significant.
But as both variables have positive coefficient so as the variable increases the price received for the item also increased.
Answer:
x = 6
Step-by-step explanation:
Let x = first number
x+4x = 30
5x = 30
Divide by 5
5x/5 =30/5
x = 6
Answer:
