Ans The first answer.
Step-by-step explanation:
(0,-1)
Answer:
Step-by-step explanation:
eq. of a circle is (x-h)²+(y-k)²=r²
where center=(h,k)
and radius=r
so (x+2)²+(y+5)²=4²
= -2(1/3x)
=-2/3x
you multiply the bracket first and then times -2.
Answer:
The strong linear relationships are:
r = 0.95
r=-0.83
Step-by-step explanation:
When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.
Therefore r = 0.95 suggest strong linear relationships.
Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.
I hope it helps you!
Answer:
11:54pm
Step-by-step explanation:
Key details in the Question:
- Starting at 11:00 pm a bus makes a stop every 27 minutes.
- starting at 11:00pm a taxi makes a stop every 18 minutes.
The task is to find the time in which both the bus and taxi would make a stop.
Since the taxi has the shorter duration for a stop, we would use it as the basis for our calculations.
During the first taxi stop - 11:18pm
The Bus has not yet made its stop.
During the second taxi stop - 11:36pm
The Bus has made it's first stop (11:27pm) but is currently on the road.
During the third taxi stop - 11:54pm
The Bus would also be making it's second stop
