Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together.
The second one is almost a straight line so it would be very close to 1. I would say 0.97
The closer the data is to a straight line the closer the r value is to 1 or negative 1.
Hope this helps.
The perimeter would be 3/8+3/8+4/5+4/5= 2.35 or 2 7/20 square foot.
I hope this helps.
YOU'RE WELCOME :D
Answer:
7
Step-by-step explanation:
I took the k12 quiz
55 degrees
The supplementary angle is 55 because 180-125=55
Then subtract the interior angles 180-75-55=55
