1.what is the volume of the small cone in terms of pi

svp [43]

Step-by-step explanation:

Step 1: Find the radius of the big cone

$\frac{radius_1}{height_1} = \frac{radius_2}{height_2}$

$\frac{2}{5}=\frac{x}{10}$

$2(10)=5(x)$

$20/ 5=5x / 5$

$4=x$

Step 2: Find the volume of the small cone

$V = \frac{\pi*r^2*h} {3}$

$V = \frac{\pi * 2^2 * 5}{3}$

$V = \frac{20\pi}{3}\ units^3$ ← Volume of Small Cone

Step 3: Find the volume of the large cone

$V = \frac{\pi*r^2*h} {3}$

$V=\frac{\pi*4^2*10}{3}$

$V = \frac{160\pi}{3}\ units^3$ ← Volume of Large Cone

Which of the following is true about multi-collinearity? Group of answer choices The P-value reduces significantly, leading to r

julsineya [31]

Answer:

It is measured using a measure called variance inflation factor (VIF).

Step-by-step explanation:

This is the statement that is true about multi-collinearity. Multi-collinearity is a situation that can sometimes arise when dealing with a multiple regression model. Multicollinearity refers to the occurrence of high intercorrelations among various independent variables. This can often lead to results that are skewed or misleading. The main way in which multi-collinearity can be measured is by using the variance inflation factor (IVF). This allows us to quantify the severity of multi-collinearity.
