AI Thread Summary
To determine the value of 'x', the masses of the rocks collected by Emily and Ashli need to be clearly defined. The mean mass of Ashli's rocks is 0.2 kilograms greater than that of Emily's, but the specific masses are not provided. Without knowing the individual masses or the total mass of either collection, calculating 'x' is impossible. Additional data regarding the rocks' weights is essential for solving the problem. Clarifying this missing information is crucial for finding the value of 'x'.

Emily and Ashli each collected six rocks, and the masses of the rocks
are shown in the table below. The mean of the masses of the rocks
Ashli collected is 0.2 kilogram greater than the mean of the masses
of the rocks Emily collected. What is the value of ‘x’ ?

I have moved your post to its own thread, as this is a better fit than in an announcement regarding the anniversary of our founding. ;)

It seems some information is missing...

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
