254个偏旁部首,280个独体字,组合起来有多少个汉字?

B

实验测得254个被试进行情感诱发的EMG信号,选出有效激发情感的EMG信号降噪处理后,提取其以下7个统计特征：均值、中值、标准差、最小值、最大值、最小值比率、最大值比率,同时做一次差分和二次差分也提取以上7个统计特征,得到时域的21个统计特征；针对EMG信号的特点,然后根据式（1）采用具有正交性、紧支性的Daubechies5小波作为基函数,对降噪后的EMG信号做5层分解,提取小波分解每一层细节系数的21个统计特征,这样总共可以得到126个原始特征.
Experiment measured 254 were tested for emotion-induced EMG signal,elected and effective noise reduction to stimulate feelings of EMG signal processing,extracting the following seven statistical features:mean,median,standard deviation,minimum,maximum,minimum value ratio,the maximum rate at the same time do a difference and second difference is also more than 7 extract statistical features,are the 21 time-domain statistical features; for the EMG signal characteristics,and then according to equation (1) using a orthogonality compactly supported wavelet as the base of Daubechies5 function of the noise after the EMG signal with 5-layer decomposition,extracting the details of each level of wavelet decomposition coefficients of 21 statistical features,so that you can get a total of 126 original features.

很高兴为您
8月15日起客户实际需要的Licenses总数254个,目前开通的Licenses总数是291个,多了37个User Licenses,需要减少,请处理.
The licenses actually needed by the clients is 254 on Aug.15.Currently the total number of opened licenses is 291,37 user licenses more than those of required which need reducing.Please help handle this issue.
PS：之前已提交了两个Order,订单号为：*****,要求减少Licenses,均未被处理,请核实
PS:The previously presented two orders with No.**** are required to cut down the licenses,which hasn't been processed.Please check it.

选b,15个,人数分别是
9,11,12,13,14,15,16,17,18,19,20,21,22,23,24

我个人认为答案是B15.原因可能在于对“不小于20”的理解,“不小于20”那么包括20,因为20不小于20,所以9,11这两个数是符合要求的.因而符合条件的人数为：9,11,12,13,14,15,16,17,18,19,20,21,22,23,24
这15个数的和正好是254,而且从题目中要求单位个数最多,15个多于14个.个人认为正确答案为15,参考答案是错的.大家觉得呢?

3道题都用两种方法解么 还是各选1种方法
