Math Algorithm Used to Find Missing Persons

November8

Lord Lucan and a pensioner in Australia have been matched as “the same individual” by a facial recognition expert who unmasked the Skripal poisoners and Jamal Khashoggi’s killers. Professor Hassan Ugail believes his world-leading AI photo analysis technology may have cracked Britain’s most infamous murder mystery as a matter of “science and mathematical fact”. Professor […]

Play it Forward, Rugby Style

May7

Rugby can be a complex game, but there is one rule clearly understood by all: you cannot pass the ball forward. Though the concept might sound simple, it can be difficult to officiate. When it comes to marginal calls, referees can get assistance from a Television Match Official, a secondary referee who reviews video footage, […]

Algorithms are not Al-ways right!

August24

Philip is among 300,000 pupils in England, Wales and Northern Ireland who woke on August 13 to critically important A-level exam results. These exams were cancelled this year due to the pandemic. Student marks were instead determined by an algorithm, which was chosen by the government’s exam regulator. The model drew on a collection of data […]

Machine Learning – More Mathemagic!

March24

“When your bank calls to ask about a suspiciously large purchase made on your credit card at a strange time, it’s unlikely that a kindly member of staff has personally been combing through your account. Instead, it’s more likely that a machine has learned what sort of behaviours to associate with criminal activity – and […]

Future job? Don’t bank on it!

June16

  Squeezed by low interest rates, shrinking trading revenue, and nimbler technology-based competitors, banks are preparing for the day that machines made by men and women take over more of what used to be the sole province of humans: knowledge work. The human brain is a wondrous machine, but it isn’t changing. The pace of […]

New Algorithm to predict Tsunamis

May28

Scientists at the Australian National University have a plan to improve tsunami warning systems around the globe: they’ve built an algorithm. Using data from monitors in the ocean and modeling what a tsunami looked like when it was birthed, the team of researchers can better predict how big it is, where it’s going, and who’s […]

Echo..echo..echo

June24

“A snap of a finger, a handful of scattered microphones and a computer algorithm are all it takes to create an accurate three-dimensional map of a room, say Swiss and US researchers. The method, described recently in the US journal the Proceedings of the National Academy of Sciences, measured the distance between echoes to create maps of […]

Hidden Rabbit? Clue: check the trees

How long for the stadium to fill? 45 minutes.

Where are you? the North Pole

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Popular Math Problems Answers: 1, 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Number of different nets to make a cube is eleven – see this link

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
