 <span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333..... 
the good explanation of your answer is that 0.999999....is equal to 1 
we can prove it by the following way: 
let x=0.9999.... 
then 10x = 9.999999..... 
subtract we will get 10x - x = 9.9999....- 0.99999...... 
which gives us 9x = 9 and therefore x =1 
i hope this will help u with your confusion.......  :)</span><span>

Answer:

draw a number line from 66 to 81

make your minimum 67

lower quartile should be on 70

the median on 77

upper quartile and maximum on 80

(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)

You can search up "box plot" and go on images to see what i mean

(copy and pasted from your last post!)

Step-by-step explanation:

I can probably help on part 4 and send a sketch but I currently can't use my phone to send a pic and I am currently on my desktop :'(
