Mark True/False for functional dependencies of the following table R(A, B, C, D, E), where we assume that it is the intent of the designer that exactly this set of rows should list in the table. A B C D E a1 b1 c1 d1 e1 a2 b2 c2 d2 e2 a1 b1 c1 d1 e2 a2 b2 c3 d4 e2 (a) A --> B (b) B --> A (c) C--> A (d) D --> A (e) CD --> B
The data on the table follow an exponential model y-aebx, Fill in the blanks 0.4 800 [a1] [b1] [c1] [d1] 0.8 975 [a2] [b2] [c2] [d2] 1.2 1500 [a3] b3] [c3] [d3] 1.6 1950 [a4] b4] [c4] [d4] 2 2900 [a5 [b5] [c5] [d5 2.3 3600 [a6] [b6] [c6] [d6] Sum [a b c7] [d7] The average value of w is [e1] The average value of z is [e2] a1- [e3] a0- [e4] а» [e5] b- [e6]
Assume that in A1, A2, A3, and A4 you have the values of 1, 2, 3, and 4, respectively. In B1, C1, and D1, have the letters a, b, and c, respectively. In B2, C2, and D2 you have the letters of d, e, and f, respectively. In B3, C3, and D3 you have the letters of g, h, and i, respectively. What will the command of =VLOOKUP(3,A1:D4,3) return? Group of answer choices h c a g i
MATLAB: Do the following with the provided .m file (b) Now on the MATLAB prompt, let us create any two 3 × 3 matrices and you can do the following: X=magic(3); Y=magic(3); X*Y matrixMultiplication3by3(X,Y) (c) Now write a new function in MATLAB called matrixMultiplication that can multiply any two n × n matrix. You can safely assume that we will not test your program with matrices that do not have their inner dimensions matched up CODE: function [C] = matrixMultiplicationFor3by3(A,B)...
2. a. To be eligible for a company bonus, an employee must earn a yearly sales commission over $10,000 or more and have added at least 50 new sales accounts in that same year. In a spreadsheet, the employees’ names are listed in column A, their commissions are entered in column B, and the total number of new sales accounts are entered in column C. Write an IF statement in cell D2 for the employee in row 2 to be...

Can someone fix my coding please it's a calendar some days are placed wrong. I just want the Main menu to display first and second option and four option to end the program properly. Please remove option number 3 Find the number of days between 2 selected dates and the code that belongs to this function. #include<stdio.h> void days(int,int,int,int,int,int); int month(int,int); int mon[12]={31,28,31,30,31,30,31,31,30,31,30,31}; #define TRUE 1 #define FALSE 0 int days_in_month[]={0,31,28,31,30,31,30,31,31,30,31,30,31}; char *months[]= { " ", "\n\n\nJanuary", "\n\n\nFebruary", "\n\n\nMarch", "\n\n\nApril",...

1. Show that Corr(aX + b, cY + d) = Corr(X, Y) using the definition of correlation in page 249, and finding each component first. Correlatiorn DEFINITION The correlation coefficient of X and Y, denoted by Corr(X, Y), or ρχ.r, or just ρ, is defined by Ox-GY
