A prime polynomial is one that can only be divided by itself and 1. Let's check it option.
A. x³-bx²
This polynomial can be divided by itself, 1, x and x². So it can't be prime.
B. x²-4x-12
This polynomial represents the standard form of a second order polynomial. This means that it is a parabolla. A polynomial of this form can be divided by (x-a) where "a" is the value of its roots. So it can't be prime.
C. x+8xy³
This polynomial can be divided by x, 1 and itself, therefore it can't be a prime.
D. x²-b³
This polynomial can only be divided by 1 and itself. So this is the correct answer.
Yes they are prime if that's the question u just asked
Answer:
68.269%
Step-by-step explanation:
We start by calculating the z-scores of both numbers
Mathematically;
z-score = (x-mean)/SD
where x represents the raw score
For 82;
z-score = (82-87)/5 = -5/5 = -1
For 92;
z-score = (92-87)/5 = 5/5 = 1
So the probability we want to calculate would be;
P(-1 < x< 1)
We can use the standard normal distribution table to get this.
By using the distribution, P(-1<x<1) = 0.68269
By converting this to percentage, we have 68.269%
Answer:
Hello, Your answer is 1.02$
Step-by-step explanation:
First of all, let's calculate the total amount payed by Veena for her meal: t =9.25$ + 4.35$ =13.6$ The tax was 7.5%, which corresponds to a fraction of 7.5% =7.5/100 therefore, the amount of tax payed by Veena for her meal is tax = 7.5/100 . t = 7.5/100 (13.6$) =1.02$<em> Hope This Helps!</em>
Answer:
C) 20,000
Step-by-step explanation:
100,000 increase in 5 years
100,000÷5=20,000
=20,000 increase per year
