Answer:
x=-19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x+18+6x+9=7x+8
9x+27=7x+8
9x+27-7x=8
2x+27=8
2x=8-27
2x=-19
x=-19/2

Answer:
The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is__3.5%___ which is___significant_(at α=0.05)_ so there _is_ sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles.
Step-by-step explanation:
Correlation coefficient shows the relation between the <em>weights</em><em></em> and <em>highway fuel consumption amounts</em> of seven types of automobile.
P-value states <em>the significance</em> of this relationship. If the p-value is lower than a <em>significance level</em> (for example 0.05) then the relation is said to be significant.
