"Linearity of Expectation" I asked this question before few minutes and someone answered me with this phrase, but I searched in youtube and could not understand the relationship, maybe he did not understand the question correctly, so I will ask again, sorry

the answer is 100 because the mean of the sampling distribution is the same as the mean of the population.

even if I would say zscore = (meanOfTheSample - meanOfThePopulation) / SE >> zscore = (meanOfTheSample / 100) / 10, this is wrong as well because I do not know the meanOfTheSample

I've been trying to solve this equation for a few hours, changing variables, using logarithms. I tried calculating it in Wolfram Alpha but for some reason it doesn't show the exact value and only shows a decimal approximation. How can I find the exact value of x?

Wolfram alpha might have used a method like newton-rhapson method, it's possible you cannot find the answer analytically
