Getting value from statistical data – future jobs for mathematicians!

February20

In 2009, Hal Varian, Chief Economist at Google and emeritus professor at the University of California, predicted, “I keep saying the sexy job in the next ten years will be statisticians…The ability to take data – to be able to understand it, to process it, to extract value from it, to visualise it, to communicate […]

Mathematics helps design wind turbines

November11

Mathematics contributes in many ways to the process of converting wind power into usable energy. For example, mathematical weather models are used to find suitable locations for wind farms, while other models specify how to place individual turbines within a farm. Finally, Mathematics (through the use of fluid dynamics) describes air flow and drag around […]

Mathematician Terry Speed wins prestigious award

October31

Earlier this week, Mathematician Terry Speed was declared the overall winner of the $300,000 Australian Prime Minister’s Prize. Mr Speed’s statistical expertise has been used in several high-profile court cases, including that of O.J.Simpson in the USA. Part of this Court Case work involved calculating the odds of a chance DNA match, verses a real match […]

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)?]
