a bird of species a when diving can travel four times as fast as a bird of species b top speed if the total speeds of these two

weeeeeb [17]

X will be the speed of species b and 4x will be the speed of species a:

x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h

If species b has a speed of 36 m/h, the speed of species a is 4 times that:

4 x 36 = 144 m/h.

Answer:

$\boxed {\bf A~=~36~m/h~and~B~=~144~m/h}$

Hope it helped,

Happy homework/ study/ exam!

Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couple

yulyashka [42]

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

Please check the attachment for the table, it will aid you in understanding the solution
