Um not sure but thanks for asking:)
Answer:
11/7
Step-by-step explanation:
22/7 divided by 2 = 22/7 multiplyed by 1/2 = 22/14 = 11/7
I don't really know what the second sentence means, so plz tell me, but here 22/7 minus 2/3 is 52/21
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
Answer:
your estimate would be $86.22
Step-by-step explanation:
V=length times width times height
wait, we need it in yards
3ft=1yard
so height=1
v=45 times 30 times 1
v=1350 cubic yards
1 cubic yard=201.974 gallons
so times both sides by 1350
272664.9 gallons
per every 5000 gallons of water we have 1 of chlorine
so 272664.9/5000=54.53298
so we need about 54.5 gallons or 55 gallons of cholrine
