Statistics
Today we learnt about statistics using mean median and mode. Mean stands for average, to find the mean you have to add all your numbers and divide the answer you got with how much numbers are there. Median is just like the middle and mode the most occurring number so like the number that appeasers the most.
This is the data room 7 and I worked on.

Measurement task for Friday 5 March 2021
Please make a copy of this document and save it to your maths folder
Try to solve the problems independently.
You may use diagrams to explain your thinking.
We will discuss as a group what strategies you used to solve the problems
WALT: use multiplicative and/or additive strategies to solve measurement problems.
A student measures her height with a 30 cm long ruler.
She finds that she is four and a half rulers high. How tall is
she in cm? 30cmx4=120cm ½ of 30cm=15cm 120cm+15cm=135cm
A student is told that they are 1.45 m tall. How tall is this in cm? 145cm
If it takes 3 hours to drive 210 km, what was the average speed of the journey?
210 divided by 3=70kph
A class of 28 is split into small groups. How big can those groups be?
Factors of 28 1 2 4 7 14
A car, travelling at an average speed of 70 km/ph is in a journey of 210 km.
How long will the journey take? 70x3=210km so it will take 3 hours to get there.
A long distance swimmer takes 80 strokes to swim 100 metres.
He wants to swim across Lake Taupo, a distance of 4200 metres.
a. How many strokes will it take for him to swim across the lake?
b. If he can swim at a rate of 60 strokes per minute, how many
minutes could he swim across the lake in?
c. Can he expect to beat the 2015 champion swimmer who
crossed the lake in a time of 51 minutes and 48 seconds?
No because he did it in 56 minutes and the swimmer did it in 51 minutes.

Maths
One third of the animals in the barn are chickens. The rest are pigs.
There are 20 legs in all.
How many pigs are there? There are four pigs.
If ⅓ are chickens then ⅔ are pigs. Each chicken has two legs and each pig has four legs.
I have three dogs of different ages.
If I add their ages together I get 15.
If I multiply their ages together I get 45.
How old are my dogs? The dogs ages are 1, 5, and 9
Because 1+5+9=15 and 9x5x1=45
Niko and Kaia buy their father a card for Fathers’ Day.
The card costs $5.90. Niko puts
in 40c more than Kaia.
How much do they each contribute
to the card?
Half of $5.90 is $2.95 Niko put 40c more
so Niko payed $3.15 and Kaia payed $2.75
I think that you’ll find a pattern in the numbers below.
8 x 8 + 13 =77
88 x 8 + 13 =717
888 x 8 + 13 =7117
8888 x 8 + 13 =71117
88888 x 8 + 13 =711117
Does the pattern extend indefinitely?
Yes Because 88888888888x8+13=
711111111117
