Answer:
Width of river = 0.25 mile
As length of river is not given , but it is given that campsite is located 1 mile east upstream, So length of river = 1 mile
Speed of mine in river while going upstream = 3 miles per hour
Speed of current as going Upstream = 1 miles per hour
Now Reduced speed of mine = Speed of mine in river while going upstream - Speed of current as going Upstream
= 3 - 1
= 2 miles per hour
1. There are two ways to reach campsite
(a) either walk 1 mile from starting point in east direction and then swim 0.25 mile in North direction to reach campsite.
Or
(b) From the starting point Considering a right triangle having, base=1 mile and altitude = 0.25 mile, then finding the length of hypotenuse using formula =
=
=√1.0625
=1.03078(approx)
⇒ you must walk a distance of 1 mile in the east direction and then swim 0.25 mile north direction to reach directly at campsite.[shown in the diagram]
Answer: substancially lower / more to the left
If the data is skewed to the left the mean will be moved more to the left so it will decrease. The mean is greatly changed by the skew of the data
Say x=5.764---
Then 1000x=5764.764---
Then 1000x-x = 5759
So 999x = 5759
So x=5759/999
I don't see how b can be 0 in this case... what does that mean? You would never divide by 0 and live to tell about it, right?

Read it carefully as it may look confusing with the symbols.
Answer: 2.625
Step-by-step explanation:
All you have to do is divide 5 by 8 which gives you .625 and then you put the 2 in front of the decimal amd you get your answer.
