Answer:
C) -1.255
Step-by-step explanation:
We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:
Residual value = Observed value - predicted value
Residual value = 26 - 27.255
Residual values = -1.255
The answer is -1.255 for residual value.
Answer:
215 cm³
8.6 cm
Step-by-step explanation:
given,
density = 10.2 g/cm³
mass = 2.193 kg = 2193g
a. Volume = mass / density
=2193 / 10.2
= 215 cm³
b. given that base area = 25cm²
volume = base area x thickness
thickness = volume / base area
= 215 / 25
= 8.6 cm
