According to the article "modeling and predicting the effects of submerged arc weldment process parameters on weldment characteristics and shape profiles" (j. of engr. manuf., 2012: 1230-1240), the submerged arc welding (saw) process is commonly used for joining thick plates and pipes. the heat affected zone (haz), a band created within the base metal during welding, was of particular interest to the investigators. here are observations on depth (mm) of the haz both when the current setting was high and when it was lower. non-high 1.04 1.15 1.23 1.69 1.92 1.98 2.36 2.49 2.72 1.37 1.43 1.57 1.71 1.94 2.06 2.55 2.64 2.82 high 1.55 2.02 2.02 2.05 2.35 a. construct a comparative boxplot and comment on b. is it reasonable to use the two-sample t test to test 2.57 2.93 2.94 2.97 interesting features. hypotheses about the difference between true aver- age haz depths for the two conditions? does it appear that true average haz depth is larger for the higher current condition than for the lower condition? carry out a test of appropriate hypotheses using a significance level of.01.

step-by-step explanation: the declaration of the rights of man and of the citizen (french: déclaration des droits de l'homme et du citoyen de 1789), set by france's national constituent assembly in 1789, is a human civil rights document from the french revolution.[1]

the declaration was drafted by the abbé sieyès and the marquis de lafayette, in consultation with thomas jefferson.[2] influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. it became the basis for a nation of free individuals protected equally by the law. it is included in the beginning of the constitutions of both the fourth french republic (1946) and fifth republic (1958) and is still current. inspired by the enlightenment philosophers, the declaration was a core statement of the values of the french revolution and had a major impact on the development of freedom and democracy in europe and worldwide.[3]

the 1789 declaration, together with the 1215 magna carta, the 1689 english bill of rights (1689), the 1776 united states declaration of independence, and the 1789 united states bill of rights, inspired in large part the 1948 united nations universal declaration of human rights

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
