It's B.

If 0<x<1, then it's also the case that 0<x^2<1, because multiplying any number x by a number (in this case, also x) between 0 and 1 scales that number down.

It's not C, because 2^2=4\neq3.

It's not D, because 3^2=9\neq3.

Answer:

Step-by-step explanation:

Let the yellow cubes be x

according to the question ,

blue cubes r twice of yellow

green is 4 times of blue

yellow = x

blue = 2x

green-8x

Ratio:

Use the given information to find the indicated probability. a and b are mutually exclusive. p(a) = .8, p(b) = .1. find p((a ∪ b

alexgriva [62]

If $A$ and $B$ are mutually exclusive, then

$\mathbb P(A\cup B)=\mathbb P(A)+\mathbb P(B)=0.8+0.1=0.9$

Then $\mathbb P((A\cup B)')=1-\mathbb P(A\cup B)=0.1$ .

cylinder has radius 2.5 cm and lateral area 20π cm2.20π cm2. 20 pi . cm squared , . What is the surface area of the cylinder in

uysha [10]

$\bf \textit{lateral area of a cylinder}\\\\
LA=2\pi rh\qquad 
\begin{cases}
r=radius\\
h=height\\ -----\\
LA=20\pi \\
r=2.5
\end{cases}\implies 20\pi =2\pi \cdot 2.5h
\\\\\\
\cfrac{20\pi }{2\cdot 2.5\pi }=h\implies \boxed{4=h}\\\\
-------------------------------\\\\
\textit{total surface area of a cylinder}\\\\
SA=2\pi r(h+r)\implies SA=2\pi \cdot 2.5(4+2.5)$

A line is an undefined term because it. . contains an infinite number of points. . can be used to create other geometric shapes.

Veseljchak [2.6K]

The correct answer is statement number 3. A line is an undefined term because it describes something that does not have width or depth. However, lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.
