Economic mathematics; formative assessment; answer（经济数学基础形成性考核答案） If the series and the absolute convergence, then the series must absolutely converge.Y The series of series converges if and only if for each fixed satisfying condition y If the limit function of the continuous function column is discontinuous on the interval I, its function is listed in the interval I, and the convergence is not y If the convergence is uniform on the interval, the upper uniform convergence is y If the function has any order of derivatives, it exists so that it can be expanded into a Taylor series. N Function can be continuous, continuous must guide. N Extreme points must be included in the interior of the interval, the stationary point or the point where the derivative does not exist. Y The linear regression gives the estimated equation of y=38+2x. At this point, if the value of the future x is known to be 30, then we can predict that the estimate of Y is (). Ninety-eight The following relation is the square, length and area of the relation The variance of the sample variance is different from the variance in the numerical characteristics of the random variable, which is divided by the observation value to the mean, the distance and the square sum by the sample size by 1 instead of the direct by the sample size The main content of n is less than or equal to 30 for the sample below, without calculation of the average data packet is (). Direct addition (in investment practice) is evolved into the famous K line chart box diagram When the event A occurs simultaneously with B, the event C must occur, and the correct conclusion is (). PC greater than or equal to pa+pb-1 Statistics are based on (the) theory, which studies random phenomena based on the data obtained from experiments or observations, and makes reasonable estimates and judgments about the objective laws of the subjects. probability theory It is known that the probability of shooting at any one shot is 0,5, a continuous shootin
