So the 5th position has an index of 4. } System.out.println("This is the value at position 5: " + valueAt5thPosition); // return the integer value found at position 5 of the array... return valueAt5thPosition; ▾ Description A MathVector object will be passed to your method. Return the 5th element inside of that object. If you look in the file MathVector.java you'll see there is a way to extract the value of one element in the array contained inside a MathVector object: *Returns the element at the specified index. * @param index the index of the element to return * @return the element at the specified index */ public int at(int index) { return array[index]; } use it like myObject.at(4); to get the 4th element. You did similar operations (with a different syntax) with Matlab. What to reproduce this on your own machine? Here are some important files: preLabC.java (fill this in) • MathVector.java (the class with all the methods that the student should explore) • MyTest.java (the JUnit testing file. Student can use this on their own computer if they wish)

Include a formula in the last column on the third row to calculate 75% of the Cost. The formula is =0.75*b3. You do not need to select a number format. Include a formula in the next two rows of the same column, adjusting the row reference as necessary.

Add formulas to complete the table of hours used. In cell B17, create a nested formula with the IF and SUM functions that check if the total number of hours worked in week 1 (cells B9:F9) is equal to 0. If it is, the cell should display nothing (indicated with two quote marks: ""). Otherwise, the cell should display the total number of hours worked in week 1. Copy the formula from cell B17 to fill the range B18:B20

How would you create that chart up top with the destination,reg price, reduced and sales price using that same flight_sales text file?

Create lookup functions to complete the summary section. In cell I6, create a formula using the VLOOKUP function to display the number of hours worked in the selected week. Look up the week number in cell I5 in the range A17:G20, and return the value in the 2nd column. Use absolute references for cell I5 and the range A17:G20.

The APPT_DTTM column stores the date and time of an appointment. Which of the following expressions would return TRUE for all appointments on January 1, 2018, and FALSE for all other appointments? SELECT ONE OF THE FOLLOWING A. APPT_DTTM >= '1 JAN 2018' AND APPT_DTTM < '2 JAN 2018' B. APPT_DTTM = '1 JAN 2018' C. APPT_DTTM > '31 DEC 2017' AND APPT_DTTM <= '1 JAN 2018' D. APPT_DTTM > '31 DEC 2017' AND APPT_DTTM < '2 JAN 2018' Choose one correct answer and what is output of remaining queries with proper explanation

Please help me with the syntax to create a table in Snowflake.

Excel date fields have the date to the right of the decimal point, and time to the left of the decimal point. True False

Update the validateForm() function to verify the phone number is exactly 10 characters long. Display "Phone number is invalid" in the console log if the phone number does not meet the requirements. Use the preventDefault() function to avoid submitting the form when the input is invalid.
