Step-by-step explanation:
-4h + 22 + 6h -7
2h + 22 - 7
2h + 15
Check the picture below
notice, the run is half 35
recall slope = rise/run

Answer:
1,338.75 miles in 3.5 days.
Step-by-step explanation:
What I did was first, 765/2=382.5
Then I did 382.5x3.5=1338.75(rounded 1339 or 1340)
Hope this helps.
Answer:
There is a linear correlation between chest size and weight,0.8482
Step-by-step explanation:
Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.
the value of the linear correlation coefficient is r = 0.921.
i.e. there is a strong positive correlation from the value of r.

(Two tailed test at 5% level for correlation coefficient)
Test statistic t = 
p value <0.00001
Since p is less than 0.05 we reject H0
a) There is a linear correlation between chest size andweight
b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
