We have an urn with 3 green and 4 yellow balls. We choose 2 balls randomly without replacement. Let A be the event that we have
Nana76 [90]

Answer:

Step-by-step explanation:

Urn has 3 green and 4 yellow

we choose 2 balls randomly

so samples  space for this selection is

\left [ \left ( Y,G\right ),\left ( G,Y\right ),\left ( G,G\right ),\left ( Y,Y\right )\right ]

Event A is choosing differently colored ball form sample space

P(A)=Probability of event (G,Y)+Probability of event (Y,G)

=\frac{^3C_1\times ^4C_1}{7\times 6}+\frac{^4C_1\times ^3C_1}{7\times 6}

=\frac{4}{7}

Determine whether the following equation defines y as a function of x.
Aleks04 [339]

Answer:

The equation can define y as a function of x and it also can define x as a function of y.

Step-by-step explanation:

A relation is a function if and only if each value in the domain is mapped into only one value in the range.

So, if we have:

f(x₀) = A

and, for the same input x₀:

f(x₀) = B

Then this is not a function, because it is mapping the element x₀ into two different outputs.

Now we want to see it:

x + y = 27

defines y as a function of x.

if we isolate y, we get:

y = f(x) = 27 - x

Now, this is a linear equation, so for each value of x we will find an unique correspondent value of y, so yes, this is a function.

Now we also want to check if:

x +  y = 27

defines x as a function of y.

So now we need to isolate x to get:

x = f(y) = 27 - y

Again, this is a linear equation, there are no values of y such that f(y) has two different values. Then this is a function.

Which figure has an order 3 rotational symmetry? right triangle equilateral triangle regular hexagon right trapezoid
kvv77 [185]

Answer:- Equilateral triangle has an order 3 rotational symmetry.


Explanation:-

In geometry, a figure has rotational symmetry if it moves onto itself under rotation about an angle at center of rotation.


The order of rotational symmetry is the number of times the shape moves onto itself throughout a rotation of 360°.

An equilateral triangle has all its sides equal with equal interior angle of 60°.

It moves onto itself three times throughout a rotation of 360°.

⇒Equilateral triangle has an order 3 rotational symmetry.
