This pentagon can be split into three triangles, so the total for this pentagon is 540°. Add up all angles to equal 540°.
x= unknown angle
90° + 107° + 144° + 138° + x= 540°
479 + x= 540
subtract 479 from both sides
x= 61
CHECK:
90 + 107 + 144 + 138 + 61= 540
540= 540
ANSWER: x= 61°
Hope this helps! :)
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.
