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.
I believe the answer is 16/9
180 - 46 - 24 = 110
d+ 80 = 110
d = 30
answer
d = 30
Answer:
Step-by-step explanation:
First, write an equation. 55x+40=190.
X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The +40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.
55x+40=190
55x=150
x=2.72727272...
So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
