An engineer believes that there is a linear relationship between the thickness of an air filter and the amount of particulate ma

tter that gets through the filter; that is, less pollution should get through thicker filters. The engineer tests many filters of different thickness and fits a linear model. If a linear model is appropriate, what should be apparent in the residual plot

Answer:

If the model is appropiate, the residual of a linear regression model, when plotted in a scatter plot (residuals vs. independent variable), should be spread around 0, with no significant slope (slope = 0).

Step-by-step explanation:

The residual is defined as the difference between the observed and the predicted value.

If the model is appropiate, the residual of a linear regression model, when plotted in a scatter plot (residuals vs. independent variable), should be spread around 0, with no significant slope (slope = 0).

Solve the equation for x. 1 6 (2x − 12x) = 30 A) −12 B) −15 C) −18 D) −24
lubasha [3.4K]

\frac{1}{6}*(2x-12x) = 30

\frac{1}{6}*(-10x) = 30

\frac{-10}{6}x = 30

\frac{-5}{3}x = 30

\frac{5}{3}x = -30

x = -30/\frac{5}{3} = -30 * \frac{3}{5}

x = -18

the correct answer is C

Two spheres have volumes of 8,cm and 647 cmIf the surface area of the smaller sphere is 16 cm?, what is the surface
Olegator [25]

Answer:

361.7cm²

Step-by-step explanation:

Volume of sphere 1= 8cm³

=

Volume of sphere 2 = 647cm³

But volume of sphere = 4/3πr³

The radius of sphere 2

647 = 4/3πr³

((3*647)/4)/π= r³

5.36544 = r

Surface area = 4πr²

Surface area for the big sphere

= 4π5.36544²

= 361.7cm²
