Answer:
- Jon - Andrea = 1/10
- Callie - Jon = 3/10
Step-by-step explanation:
In terms of tenths, the distances each hiked are ...
- Andrea — 4/10
- Jon — 5/10
- Callie — 8/10
Then the differences of interest are ...
Jon - Andrea = 5/10 -4/10 = 1/10
Callie - Jon = 8/10 - 5/10 = 3/10
__
Jon hiked 1/10 of the trail more than Andrea.
Callie hiked 3/10 of the trail more than Jon.

Answer:
60
Step-by-step explanation:
Let x represent the number of members last summer. Then 90% more is 1.9x. We are told this is 114, so we have ...
1.9x = 114
x = 114/1.9 = 60
There were 60 members last summer.
The antiderivate of 5x is 5x^2 / 2 .
By using a scatter plot we can get the relationship of two variables or correlation.
There will be two types of correlation.
If the data of the plot show a positive slope of the estimated line then it will be a positive correlation.
Now a correlation value lie between 0 to 1 if it is very close to 0 like 0.1 , 0.2 then we can say the correlation is weak psitively correlated. and if it will be close to 1 like 0.8 or 0.9 then the correlation will be strong.
Similarly if slope of the estimated line will be negative then it will be a negative correlation.
From the above scatter plot notice that it has a negative slope and we can draw a fair estimate line on this scatter plot. So, there is strong negative correlation.
Hence the correct choice is -0.8.
