Answer:
Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=
S=
S=
S=
7 is the amount of data units given in the problem.
120/7=17.1428571429
=4.1403933560541
Nearest hundredth=4.14
I've attached an image showing the coordinates of Ship A and Ship B.
Answer:
distressed vessel is located at (1, 1.5)
Step-by-step explanation:
From the image attached, we can see that;
Coordinate of ship A is (3, 4)
Coordinate of ship B is (1, 1)
Now, we are told that Ship A receives a distress signal from the southwest, and ship B receives a distress from the same vessel from the north.
This means that the distressed ship is somewhere in between ship A & B.
To solve this, we will extend the arrow line from Ship A in that same SW direction and we will do the same for ship B in the same North direction. Their point of intersection is where the distressed ship is located.
Now, if we do that, we will see that they will intersect at the point; (1, 1.5)
Thus,distressed vessel is located at (1, 1.5)
