## Zombie Maths 2: Direct Proportion

December 13, 2011## Zombie Maths 4: Simultaneous Equations

December 13, 2011### We know the Zombie walking speed = 0.6 m/sec or 2.3 kph, rounding off.

### We know Zombie hand speed = 5 m/sec or 18 kph

### Kid walking speed is about 5 kph

### That is 5000 m

### in 60 x 60 = 3600 sec

### or , rounding off, 1.4 m/sec

.

## ……………………….y = k t

.

## ……………………….y = distance km

.

## ……………………….k = speed kph

.

## ……………………….t = time hr

# Will a Zombie catch you?

# Will a Zombie Arm catch you?

### Look at the speeds. A Zombie cannot catch you … no problem.

### BUT

### The Zombie Hand is faster than you. If it started 5km away from you, how long would it take to catch you?

### We will write two equations.

### Zombie hand Equation :

## y = 18 t – 5 ………… Eqn 1

### NB: The Zombie Hand starts 5 km away from you.

### The kid equation:

## y = 5 t ………………. Eqn 2

# How far did you walk?

### y = 5 t

### y = 5 x 0.38

### y = 1.9 km

# ARRRRRRGGGGHHHH!

## Zombie Maths 5: Trigonometry

December 13, 2011### Zombies are dumb.

### A Zombie starts walking toward your house from 10 km away.

### He walks in a straight line, but he is 5 degrees off target.

### How far away from your house will he end up away from your house?

# ZOMBIE LIKE PYTHAGORAS TOO!!!

# WORK OUT HOW FAR ZOMBIE WALK.

# The High -pot-in-use!

# Everyone must know the HIGH-POT-IN-USE!

## Zombie Maths 8: Percentages

December 13, 2011## There are 7 billion people on earth but

## BUT 54% of humans can’t swim …

## ……………. 46% can!

.

.

## Number of people who can swim is 3.22 billion.

## Zombies don’t have to swim

## … They can’t drown!!!!

## They can breathe under water

## or

## just play at the beach.

## Zombie Maths 11: Probability

December 13, 2011# Shark attack

### What is the probability of being attacked by a shark while walking around the earth?

### According to National Geographic 70 people are attacked by sharks each year.

### 70 people are attacked by sharks each year and 3.22 Billion people can swim (see above).

### .

### We will assume they swim in the sea.

### The probability is 70 in 3.22 billion or

### 1 in (3.22/70) billion = 1 in .046 billion

### or

## 1 in 46,000,000

# What is the probability of

# Zombie being eaten by a shark?

### But Zombie spends 1.42 years in water when walking around the earth. He is more likely to be gobbled up.

.

# BUT the probability is soooooo low ZOMBIE will be OK

# and

# she might even eat a SHARK!

## Zombie Maths 12: Mean, Median and Mode

December 13, 2011### Zombies don’t bleed but Hollywood keeps splattering Zombies in FAKE BLOOD in movies. So every Zombie must know the cost of FAKE BLOOD.

### So much FAKE BLOOD seems to be sold in America we have to use American volumes:

### 1 US fl oz = 29.6 ml

### 1 US pint = 16 US fl oz = 473 ml

### 1 US gallon = 8 US pints = 3785 ml = 3.79 litres

### These are approx values as manufacturers round off conversions from fl oz to ml.

### Mathspig found 3 types of fake blood out there but Halloween Blood, Stage Blood and Movie Blood.

### .

### Halloween Blood can be found @ Party City

* Mathspig used more accurate volume conversions than shown on products.
