1. Put the numbers in order from smallest to largest, e.g. 2, 6, 12, 18, etc.
Range:
To work out the range take the biggest number and the smallest number and subtract them from each other… e.g. 18-2=16 so the range is 16
Mean:
Add all the numbers together and divide by how many of them there is, e.g. 2+6+12+18=38/4=9.5 so the mean is 9.5
Median:
Again make sure the numbers are in order from smallest to biggest, start crossing out the first number then the last number then the second then the second to last until you get the middle number, e.g.-2-, 6, 12, -18- …. Since I have two numbers in the middle to find the median you have to find the number in between them, if it’s easy to spot like 5, 6 would be 5.5 you can just find it by looking but if there’s a large difference like the 6, 12 in my made up sequence just add the 2 number together and divide by 2 e.g. 6+12=18/2= 9 so the median is 9
(If there’s only one number it’s just that one number)
Mode:
Mode is the number that occurs the most, for example 2, 6, 12, 18 hasn’t got a mode but if it was 2, 6, 6, 12, 12, 12, 18
The mode would be 12 because there’s the most of it, 3 while only two 6s, one 2 and one 18.
Hope this helps! I would’ve done the answers for you but I couldn’t see the whole sequence. Good luck! :)
here's the solution,

height = 1.25 ft (approximate)
Given that:
5π/3
=5/3×180
=240°
This is in the Quadrant III
The value of cot 5π/3 will be given by:
cost θ=1/tan θ
thus
tan θ
=tan 5π/3
=tan 240
=tan (240-180)
=tan 60
using an equilateral triangle with lengths 2 units
then
tan 60=√3/1
tan 60=√3
hence
tan 240=√3
×=167
180-12=168
× and 13 are linear pair so together they equal 180
Answer:
Mr. Sato needs 9 more magnets.
Step-by-step explanation:
The 24 students will form 12 pairs. The total number of magnets needed is 12*3 = 36. Mr. Sato gave out 9*3=27 magnets already and so he will need 36 - 27 = 9 more magnets.
