P $= 0.40$ and n $= 6$

Probability that none of the graduate gets job

this means that x = 0

P (x = 0) $= ^6C_0 * (0.40)^0 * (0.60)^6$

P (x = 0) $= 0.0467$

A cylinder has a volume of 1200 meters cubed. What is the volume of a cone with the same radius and height? A. 400 m3 B. 900 m3

drek231 [11]

Hey there!

The volume of a cone is always 1/3 of that of a cylinder with the same except dimensions. You multiply the base by the height and then divide by three!

This means that if the cylinder has a volume of 1200 meters cubed, you simply divide by three, giving you 400 meters cubed !

The answer is A. 400 m³.

Fraction or decimal form round all the way!

Answer:

Solving the given expression $x+\frac{1}{2}-x=\frac{1}{2}$ we get 0=0

Step-by-step explanation:

We need to solve the expression: $x+\frac{1}{2}-x=\frac{1}{2}$

Solving the expression:

We will use simple maths rules to solve the expression

$x+\frac{1}{2}-x=\frac{1}{2}$

Subtracting 1/2 on both sides and simplify

$x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0$

Solving the given expression $x+\frac{1}{2}-x=\frac{1}{2}$ we get 0=0

So, the expression is true for all values of x. there will be infinite solutions to the system.
