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

Answer:
Y = -0.3587+0.09118X
92 %
Step-by-step explanation:
Using technology to fit the data between the variables, test score and hours of sleep; we obtain the linear model :
Ŷ = -0.3587+0.09118X
Where, x = test score ; y = hours of sleep
To obtain the test score of a student who sleep foe 8 hours using the model :
Y = 8
Ŷ = -0.3587+0.09118X
8 = -0.3587+0.09118X
8 + 0.3587 =0.09118X
8.3587 = 0.09118X
X = 8.3587 / 0.09118
X = 91.672515
X = 92 ( approximately)
