Answer:
Option (1)
Step-by-step explanation:
If a polynomial is given in the form of f(x) = ax³ + bx² + c
By rational root theorem rational roots of the given polynomial will be,
x =
Given polynomial in the question is,
f(x) = 66x⁴- 2x³ + 11x²+ 35
Possible rational roots will be,
x =
Therefore, Option (1) will be the answer.
Answer:
Step-by-step explanation:
Given that taxi Fares are normally distributed with a mean fare of $22.27 and a standard deviation of $2.20.
For a random single taxi std deviation is 2.20
But for a sample of size 10, std deviation would be
This would be less than the 2.20
Because std devition is less for sample we get a big z score for the sample than the single.
As positive values of z increase we find that probability would decrease since normal curve is bell shaped.
So single taxi fare would have higher probability than sample.
B) Here >24.
By the same argument we have z value less for single taxi hence the probability for more than that would be less than that of sample size 10
Answer:
We are given an expression and we are told to simplify it using distribution or multiplying it out.
Therefore, our final answer is
