Which of the following describes the function x4 − 3?
2 answers:
Answer:
Option D
Step-by-step explanation:
We have given that function:
We can see this through graph attached that the coordinate of planes on the left and right moves upward.
By the definition of degree of the polynomial state that highest degree of x is the degree of polynomial i.e. 4 which is even which implies that the degree of the function is even.
The above statement implies that the degree of the function is even, so the ends of the graph continue in the same direction. As the leading coefficient is positive, the left side of the graph continues up the coordinate plane and the right side also continues upward.
therefore, option D is correct

And we can find this probability with this difference and using the normal standard table:
Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
