When the function f(x) is equal to 2xn + ax2 - 6 is divided by (x-1), the reminder is -7 and when divided by (x+3), the reminder is 129. Calculate the value of "a" and "n" and hence write the polynomial function completely.
17 the larger of two number is divided by the smaller,the quotient and the reminder are 2 each. 17 5times the smaller number is divided by the larger,the quotient and the reminder are still 2 each. Find the two number.
Suppose the scores of students on an exam are normally distributed with a mean of 501 and a standard deviation of 72. Then approximately 99.7% of the exam scores lie between the integers and such that the mean is halfway between these …
