Step-by-step explanation:
Answer:
Following are the solution to the given choices:
Step-by-step explanation:
Using chebyshev's theorem
:

In point a)



In point b)

In point c)

In point d)
using standard normal variate

F(x)=x⁴-1
f'(x)=4x³
Newton’s Method: x[n+1]=x[n]-f(x[n])/f'(x[n]); x[n+1]=x[n]-(x[n]⁴-1)/4x[n]³
x₁=3.00390625
x₂=2.26215...
x₃=1.7182...
X'=X-(X⁴-1)/4X³=X-X/4+1/4X³ is a symbolic way of writing the recursive formula, where X' represents the next iteration.
When X'≈X, -X/4+1/4X³≈0; so X/4≈1/4X³; X≈1/X³, so X⁴≈1 and X⁴-1≈0. But this is f(x)≈0. Hence Newton’s Method converges to a solution.
The rate of change is x[n+1]-x[n]=-(x[n]⁴-1)/4x[n]³=x[n]/4-1/4x[n]³ or symbolically -X/4+1/4X³.
Note that the method converges to one solution. A different x₀ will possibly converge to the solution x=-1.
Answer:

Step-by-step explanation:
Let's find our C value for the quadratic equation.

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

Now, lets form the left side as a binomial squared.

Let's square both sides now:

Now, we subtract 3 from both sides to isolate the variable, X:

This means that the answers are:

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
i think its -3
hope its right and helpful
if it is then mark brainlyist
