78% of all statistics are made up.

Huh? Looks like a simple joke to me...
Thanks from Joppy

Math Focus: Yet to find out.
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.

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

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.?

Your teacher wants YOUR explanation, not ours...

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 $\sqrt3$.
