In a statistics course a linear regression equation was computed to predict the final exam score from the score on the first test. The equation of the least-square regression line was
y=10+0.9x
where y represents the final exam score and x is the score on the first exam.
Suppose Joe scores a 98 on the first exam. What would be the predicted value of his score on the final exam?

Can this be computed using elementary functions?
Filed Under Mathematics | Comments Off
I need to find
integral( x^2*cos(x^2) dx).
I tried IBP and still need to be able to do sin(x^2) to get that to work, so I think this one is “can not be computed in terms of elem. functions” and I would need to approximate. Is that correct or is there a way to compute?

Notice that 8.9 is close to a real number whose square root can be computed easily?
Filed Under Mathematics | Comments Off
Use this observation and the linear approximation to estimate (8.9)1/2. (Give your answer correct to at least four decimal places.)
please show me how to solve this step by step
thank you!

How can values of the function f(x) = √(x+2) - √x be computed accurately when x is large?
Filed Under Mathematics | Comments Off
This is from numerical methods. The answer I thought I logically guessed was that if x is large, it won’t make a significant difference on f(x) whether it’s rationalized or not. What do you think?

How were the logarithmic tables computed for the first time by Napier?
Filed Under Mathematics | 2 Comments
As 10 to the power of 2 is equal to 100,there fore logarithm of 100 to the base 10 is equal 2.In the same analysis log 3 to the base 10 is 0.4771 as per log tables.Now how this figure of 0.4771 was discovered by Napier.Similarly,how the figures for log of other numbers were calculated/discovered by Napier.
