The amount of water decreases 
pints in 12 weeks.
Solution:
The amount of water decreases in 7 weeks = 
pints
The amount of water decreases each week is same.
Let us first change the mixed fraction into improper fraction.
pints = 
pints
The amount of water decreases in 1 week
So, the amount of water decreases in 1 week is 
pints.
The amount of water decreases in 12 week
pints
Hence the amount of water decreases pints in 12 weeks.
Answer:
Bias is the difference between the average prediction of our model and the correct value which we are trying to predict and variance is the variability of model prediction for a given data p[oint or a value which tells us the spread of our data the variance perform very well on training data but has high error rates on test data on the other hand if our model has small training sets then it's going to have smaller variance & & high bias and its contribute more to the overall error than bias. If our model is too simple and has very few parameters then it may have high bias and low variable. As the model go this is conceptually trivial and is much simpler than what people commonly envision when they think of modelling but it helps us to clearly illustrate the difference bewteen bias & variance.
Answer:
Assume you will invest fixed amount x at the starting of each month
S(12): (1.00625x)*(1.00625^(12)-1)/(1.00625-1) = 2000
x=160
you will invest fixed amount 160 at the starting of each month and get 2000 at the end of the year ,which compounded 7.5% monthly.
how much will you have invested at the end of the first year ?
160*12=1920
You would look at number after the thousandths place to go up or down 72,000.
The answer is 6.63 Hope this helps!
