Wow ! I didn't know the numbers when I read the question,
but with that much riding on it, I had to go look them up and
learn something. You probably could have done the same thing
and saved yourself some money, but it's too late for that. It's all
mine now, as soon as I finish writing this answer.
In the normal distribution, 68.27% of the values lie within one
standard deviation of the mean, 95.45% lie within two standard
deviations, and 99.73% lie with three standard deviations.
Within one sigma: 68.27% of 20,000 = 13,654
13,654 light bulbs will last between 190 days and 270 days.
Within two sigma: 95.34% of 20,000 = 19,068
19,068 light bulbs will last between 150 days and 310 days.
Here's the one you asked for:
Within three sigma: 99.73% of 20,000 = 19,946
19,946 light bulbs will last between 110 days and 350 days.
Only 54 light bulbs will burn out in less than 110 days
OR keep going more than 350 days.
OK. Now you owe me.
Answer:
The statement is correct as we will simplify the ratio of adults to children and will come down this.
25 children / 15 adults
both are multiple of 15 and will be divided to come down to 5 / 3
therefore it can be said that there were 5 children for every 3 adults.
There are 52 cards in a standard deck so that would be the whole in the part/whole equation so
i... There are 13 spade cards and then 3 other aces since there are 4 suits of cards so 16/52 or about 0.30769 or 30.8% rounded
ii....There are 2 reds of each card in a standard deck along with 2 blacks so there would be 2 red kings which would be a 2/52 chance or about 0.0384 or 3.8% rounded
iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded
iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded
I think you can solve it by doing this:
10(10,000+0.06)= Final Balance
6 months + 6 months = 1 year
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
She has to pay twice a year
Now that we know that just multiply 2 by 5 and you get 10. 10(10,000+0.06)= Final Balance
So it should be 100000.6
Not sure if that's right so ask someone to check
