It is not periodic. A periodic dataset is a dataset that repeats the same pattern over time.
If you add all the numbers on the right together you get -35 then you divide by 5 which gives you the average of -7*F
Answer:
jhvghvhgvvvvvvvvvvvvvvvvvvvv
Step-by-step explanation:
The value would be zero (0) bcuz if all ends up being 0 no matter how many zeros then yes it would be 0 as the value
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.
Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.
_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
R + J = total speed
R - J = difference speed
Adding these two equations, we have
2R = (total speed + difference speed)
R = (total speed + difference speed)2 . . . . . as computed above
