78% of all statistics are made up.

Huh? Looks like a simple joke to me...

Some numbers within the first expression are hardly readable.. Unless there's a clearer copy of it somewhere, I doubt it has any meaning.

If enlarged, it's just readable, but seems to evaluate to a value greater than 100%.

Unfortunately, some of those expressions are too blurred to read. The first is a sum of powers of 2, but I cannot read the powers. 5!= 5(4)(3)(2)(1) = 120. The last term in the numerator is a power of 7, but again I cannot read the power. In the denominator, the limit, as x goes to 0 of $\displaystyle \frac{\sin(x)}{x}$ is "1" and $\displaystyle i^4$ is also "1". $\displaystyle \cos\left(\frac{3\pi}{4}\right) = \frac{\sqrt{2}}{2}$. The last is $\displaystyle \frac{\sqrt{3}}{2}$ which is about 0.8660. I strongly suspect that this is not supposed to be equal to any specific number but just an arbitrary combination of math symbols. Last edited by skipjack; February 28th, 2017 at 04:03 AM.

How did you get 78% I have been given this question in math to know what it means and have to explain it.

Newbie Joined: Feb 2017 From: Michigan Posts: 17 Thanks: 0  There is a picture of this online. My teacher bought a shirt that has this on it and we have to solve it to get points. Can someone explain what it means in detail please.?

I think the expression inside the cube root is as shown below: $$\dfrac{\left(\displaystyle \sum_{n = 1}^{15}e^{\large\ln n}\right)\Bigg({\Large5!}\Bigg) {\Bigg(}{\Large7}^{{\Large\ln}_{ \large7}\large120}{\Bigg)}}{\displaystyle \left(\lim_{x \to 0}\frac{\sin x}{x}\right){\bigg(}i^{\large4}{\bigg)} \left(\cos \frac{3\pi}{4}\right) \left(\frac{2}{\sqrt2}\right)}$$ which would make the original expression evaluate to 120%. (The expression uses $\log_7$, but that means the same as the $\ln_7$ given above.) However, the $\sqrt2$ is hard to read and might be $\sqrt3$.
