Answer:
The speed of the submarine is 15.429 miles per hour.
Step-by-step explanation:
Let suppose that both ships travel at constant velocities. As we know that both travel in opposite directions, it is supposed that cruise ship moves in +x direction, whereas submarine in -x direction. Kinematic equations for each sheep are described below:
Ship
Submarine
Where:
- Position of Diego Garcia island, measured in miles.
,
- Current positions of ship and submarine, measured in miles.
,
- Velocities of ship and submarine, measured in miles per hour.
- TIme, measured in hours.
If we know that ,
and
, then:
We clear now the velocity of submarine:
Speed of the submarine is the magnitude of its velocity, which is 15.429 miles per hour.
Answer:
the residual is 0.2032
Step-by-step explanation:
The regression line has been given as:
Y^ = 0.00753X-0.06759
The paired observation for X is (31, 0.369)
The value of X is the empathy score under subject 15 = 31
The value of the brain activity under subject 15 is 0.369
So we have y^ = 0.00753(31) - 0.06759
= 0.1658
Then the residual = y - y^
= 0.369 - 0.1658
= 0.2032
Therefore the residual is 0.2032
