Please help me answer this asap thank you Two parallel chords of a circle, MN and PQ have lengths 12 cm and 16 cm. If the diameter of the circle is

Use the normal approximation to the binomial distribution to answer this question. fifteen percent of all students at a large university are absent on mondays. if a random sample of 12 names is called on a monday, what is the probability that four students are absent?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
