X=39 you take 39 and 102 and add them which is 141 then subtract that from 180
#9 the sum of two angles is 90 degrees, creating a right angle.
#10 the sum of the two angles is 180 because the form a supplementary angle
Ok so this is what my friends told me. The mean mean the average, median means middle, mode means the value that occurs often and range is the difference between the largest and smallest values. i hope this helps any
a. "The newer car is more expensive" is false. The leftmost graph is a graph of cost versus time; you can see that as you increase in age, the cost lowers (point B to point A).
b. "The slower car is larger" is true. Middle graph is the relevant one. You can see that as cruising speed increases, the size decreases. Point A is the larger car than point B
c. We have to use multiple graphs. We see that car A is the larger car from the middle graph but car A is older than car B from the left graph. So no, the larger car is newer is false.
d. A is the cheapter car and it carries more capacity. True
