Question
In R, which function is used to view the first few rows
of a dataset?Solution
head(dataset) shows the first rows in R.
I. 2y² - 3y – 14 = 0
II. 3x² - 7x + 4 = 0
Solve the given two equations and answer the two questions that follow as per the instructions given below.
I. (1/4) + 7.5p(-2) = 3.62...
I. p2 - 19p + 88 = 0Â Â
II. q2 - 48q + 576 = 0
If x2Â - 3x - 18 = 0 and y2Â + 9y + 18 = 0, which of the following is true?
I. 3x2 - 14x + 15 = 0
II. 15y2 - 34 y + 15 = 0
I. 3p² - 14p + 15 = 0
II. 15q² - 34q + 15 = 0
I. 63x2 + 148x + 77 = 0
II. 21y2 + 89y + 88 = 0
Find the value of 'x' and 'y' in the following equation:
8x - 3y = 58
5x + 2y = 106
If x² + 2x + 9 = (x – 2) (x – 3), then the resultant equation is:
I. x2 – 13x + 36 = 0
II. 3y2 – 29y + 18 = 0
