- In the language R: Which of the following statements is NOT correct about picking colors for your figures? Select one: The scale_fill_manual() function allows us to define different gradient colors for lower or higher numerical values We should pick a graded color scheme for an ordered categorical variable (e.g., level of education) We should pick distinct colors for an unordered categorical variable (e.g., country, gender…) We should pick colors based on their ability to express the data we are plottingTask 2: The formula for the area, A, of a triangle with sides of length a, b, and c is V[s(s – a)(s – b)(s – c)] A = Where (a + b + c) s = Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of s and [s(s - a)(s - b)(s - c)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A = -1. The value of A should be returned by the function. Test the function by passing various data to it and verifying the returned value.Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
- 6. When the key is a string, a conversion of this key into an integer is required. There are three options on how the string is converted into an integer.

HINT: Option #2 use the base-27 integer (26 alphabets and a space).how would i make a javascript function as follows myChoice( items ) This function accepts a list of items as input and creates a function that returns a randomly-chosen item. After choosing a random item, that same item will be always be returned, regardless of the functions input, with one exception. If the first input is the string 'rechoose', then a new random item will be chosen and therafter returned. Examples var a = myChoice( [1, "a", 3, false] ); a( 3, 12 ) => 3 // a random value. Your code may differ. a( 51, -2) => 3 a( "happy", false ) => 3 a( [1,2,3]) => 3 a( 'rechoose') => false // a random value. Your code may differ. a( a, a ) => falseAnswer the given question with a proper explanation and step-by-step solution.
