Answer:
C) p(x) has a zero between x=2 and x=4
Step-by-step explanation:
For a polynomial p(x), means that, when p(x) is divided by , the remainder is .
This is called the remainder theorem
Therefore , means that when p(x) is divided and is 1 and respectively.
Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain on where i.e there is a zero between and
Therefore the correct answer is C
let's x represent a number
8-x = 4
Answer: 5
95 times
Probability of rolling a 5 =1/6
So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times
