In this question, some of the data is missing so its a complete question and the solution can be defined as follows:
By given question, calculating equations are:
Putting the equation (c) value in the equation (a) to calculate value:
Putting equation (c) and (d) value into equation (b):
Putting m value into equation (c) and equation (d) to calculate its value:
Calculating the s value:
Calculating the r value:
So, the final value of "m, s, and r" are "900, 1800, and 5800".

Answer:
0.01 is the difference between the 2006 study and the sampe which is negligible hence why we can't say the proportion of Americans who are afraid to fly has increased.
Step-by-step explanation:
In 2006, the proportion of Americans afraid to fly is 0.10.
Then a random sample of 1300 Americans results in 143 indication that they are afraid to fly.
The proportion for this random sample is:
0.11 is the proportion of Americans afraid to fly based on the random sample.
This proportion is not necessarily evidence that the proportion of Americans who are afraid to fly has increased because the difference between the proportion of the sample and the 2006 study is negligible.
The difference is:
and 0.01 is negligible.

Answer:
y=5/2x+2
Step-by-step explanation:
To get the slope,
(-5-0) /(0-2)=-5/-2=5/2
Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.
