Triangles RDO and RHC are similar, so you have
.. RO:RC = RD:RH
.. RO:(RD +CD) = RD:(RO +OH)
.. 6:(4 +CD) = 4:(6 +4) . . . . . . . fill in numbers
.. 6*10 = 4(4 +CD) . . . . . . . . . . product of means = product of extremes
.. 15 = 4 +CD
.. CD = 11

Find the residual if you know the actual number is 3 and the predicted value is 1.6

IgorC [24]

Answer:

The correct option is A.

Step-by-step explanation:

The difference between actual value and predicted value is called residual.

Formula of residual is

$e=y-\hat{y}$

Where, y is observed value or actual value and $\hat{y}$ is predicted value.

$e=3-1.6$

$e=1.4$

The value of residual is 1.4 and option A is correct.
