Tonya runs 8 kilometres in 60 minutes. At a rate how long would it take her to run 2 kilometers
2 answers:
Answer: 15 minutes
Step-by-step explanation:
Given : Tonya runs 8 kilometres in 60 minutes.
We know that the rate of distance covered with respect to time is given by :-
Rate of distance covered with respect to time for Tony=kilometers per minute
Let t be the time taken by her to run 2 kilometers.
Then, Rate of distance covered with respect to time =
If rate remains the same, then we have
Hence, it would take 15 minutes to run 2 kilometers.

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.
