What is the theoretical probability a fair coin will land on tails?

Harman [31]

There are two sides in a coin so the chance of getting tails is 1/2, which would be 0.5.

I'm not sure tho.

A circle with circumference 6 has an are with a 20° central angle.

Marysya12 [62]

Answer:

AHH! Geometry!

Thanks!

The arc has a length of 1/3

Step-by-step explanation:

So you first start off with this:

$\frac{20}{360}$

This is because a circle is 360 degrees, and we are talking about a 20 degree arc.

Simplifying, we get $\frac{1}{18}$

So then, you multiply the circumference with this "factor"

$\frac{1}{18} *6=\frac{6}{18}=\frac{1}{3}$

Hope this helps!

P.S. Stay Safe during quarantine!

Answer: $y^2$

Reason:

A square root represents an exponent of 1/2

So $\sqrt{y} = y^{1/2}$

Raising that to the fourth power gets us this,

$(\sqrt{y})^4 = (y^{1/2})^4\\\\
(\sqrt{y})^4 = y^{(1/2)*4}\\\\
(\sqrt{y})^4 = y^{2}\\\\$

----------------

Edit: Here's an alternative route

$(\sqrt{y})^4 = (\sqrt{y})*(\sqrt{y})*(\sqrt{y})*(\sqrt{y})\\\\
(\sqrt{y})^4 = (\sqrt{y})^2*(\sqrt{y})^2\\\\
(\sqrt{y})^4 = y*y\\\\
(\sqrt{y})^4 = y^2\\\\$

The first line is possible because raising anything to the 4th power is the same as having 4 copies of it multiplied out (eg: 3^4 = 3*3*3*3 = 81).

Then in the second line, I collected the terms into pairs

By line 3, the square root and squaring exponent cancel each other out. This only works if y is not negative.
