The function f(x) = cos(2πx) for x ∈ [0,1] is approximated by a polynomial pn interpolating f at n + 1 points xi. How should n be chosen so that the error max 0≤x≤1|f(x)−pn(x)|≤ 10−8 (i) if the points xi are equally spaced?

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
