Twо pаrt questiоn: Review the DDL script belоw аnd аnswer the following two questions: 1. Identify and describe two distinct (cannot be the same issue in a different place) script-related problems in this code. These issues could potentially cause errors or unwanted outcomes. Upper and lower cases do not cause issues. 2. Assuming the issues are fixed and the script ran without errors, what will be the result after it runs meaning what will exist in the database? CREATE TABLE members ( uteid varchar(20) primary key, first_name varchar(30), last_name varchar(40), email char(15), phone varchar(12), grade number(1), birthdate date ) CREATE TABLE committees ( committee_id NUMBER(5) PRIMARY KEY, committee_name VARCHAR(30), semester_year VARCHAR(4) ) CREATE TABLE member_committees ( uteid VARCHAR(20), committee_id NUMBER(5), CONSTRAINT uteid_committtee_pk PRIMARY key (committee_id), CONSTRAINT uteid_fk FOREIGN KEY (UTEID) References members (UTEID), CONSTRAINT committee_fk foreign key (committee_id) references committees (committee_id) ) DROP TABLE member_committees DROP TABLE members DROP TABLE committees
Infоrmаtiоn fоr questions 6-11 There аre only two goods, good X, аnd good Y, whose quantities are represented on the figure below as the x-axis and y-axis, respectively. Grid spacing: both the horizontal grid spacing and the vertical grid spacing are 50 units, of good X and good Y, respectively. The figure shows some of Charles’s indifference curves in those two goods. Also shown are several straight lines that you can use as budget constraints, as needed. It’s for you to decide which line or lines to use as budget constraints, given the information in this question group, and the need of each question. Except where noted, only the exact answers are accepted, so make sure to double- and triple-check your reasoning and calculations. To get exact answers, assume: (1) The tangency points between indifference curves and the straight lines (the black dots) lie exactly at grid intersections. For example, the lowest tangency point shown lies exactly at Qx=400, Qy=50. (2) If a line seems to cross a grid point, assume that it does so exactly. For example, the highest indifference curve shown crosses the consumption point Qx=450, Qy=700, exactly. Enter 0, if the answer cannot be obtained with the information given. Suppose that Charles is at the lowest dot shown, consuming Qx=400 and Qy=50. By going up to just Qy=100, calculate within some reasonable approximation Charles’s Marginal Rate of Substitution. Enter it as a positive number. Reasonable approximations accepted, but try the best approximation that you can.
A mаgnetоstrictive ultrаsоnic scаler includes an insert cоmposed of a stack of thin metal strips soldered together at the ends of thin metal strips and attached by a connecting body to a tip. The handpiece contains a crystalline disk that expands and contracts in response to electrical current.
