    Hey Kevin, if ure serious about your confession, I advise counting your knuckles and the spaces between them, every knuckle is 31 days, every 30 days is a gap between a knuckle, and u count knuckles on both hands

    For those who are interested in the knuckle method and don't know it basically put both yoyr fists out. (Ignore your thumbs)
    Now u have 4 knuckles of each hand, start from the left:
    First knuckle- Jan = 31 days
    the dip inbetween your knuckles(idk what its called😭) -feb = suppose to be 30 days but its feb so 28 days
    3rd knuckle- March = 31 days
    the dip- April = 30 days
    4th knuckle- May = 31 days
    Now the other fist,also count from the left (ignore thumb)
    1st knuckle- June = 31 days
    dip- July = 30 days
    2nd knuckle- August = 31 days
    dip- September = 30 days
    3rd knuckle- October = 31 days
    dip- November = 30 days
    last knuckle- December = 31 days
    To summarize it every knuckle represents 31 days and the dip in between your knuckles represent 30 days
    Hope that helps🫡 (also you kevin😭)

    Thirty days has September, April, June and November. All the rest have 31 except for February alone. This month has 28 and 29 in each leap year. This is a little nursery rhyme I learnt to remember.

    • @urgalNalz

    @hypertext8863 2 роки тому +3

    isn't the answer to 1.1.1 3 because the number three is also outside one standard deviation of 25?

    • @kevinmathscience
      @kevinmathscience  2 роки тому +2

      Just be careful. I nearly got caught out there as well. They only want it where it is one standard deviation GREATER than the mean. They only want us to look at the upper part.
