Answer:
b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost
Step-by-step explanation:
The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.
If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
Answer: I believe it is D

Answer:
5 cents
Step-by-step explanation:
Let m = cost per message
450m + 12.5 = 35 subtract 12.5 from both sides
450m = 35-12.5
450m = 22.5 divide both sides by 450
m = 22.5/450
m = .05
The cost is $.05 per message ... 5 cents
