1.If the mean and the standard deviation of the data 3,5,7,a,b3, 5, 7, a, b3,5,7,a,b are 555 and 222 respectively, then aaa and bbb are the roots of the equation:a.x2−10x+18=0x^2 - 10x + 18 = 0x2−10x+18=0b.2x2−20x+19=02x^2 - 20x + 19 = 02x2−20x+19=0c.x2−10x+19=0x^2 - 10x + 19 = 0x2−10x+19=0d.x2−20x+18=0x^2 - 20x + 18 = 0x2−20x+18=0Login to continueOnly logged in users canattempt or see the solution.
