To check if the binomial is a factor, we take it in the form of x – c = 0 and then x = c, then substitute the value of c into x on the polynomial equation. It is only a factor when the value of f(x) = 0

a. x – 1

x = 1

Substitute x = 1 into the equation.

f(x) = 1^3 + 3 * 1^2 – 25 * 1 – 75

f(x) = -96

(not a factor)

b. x – 3

x = 3

Substitute x = 3 into the equation.

f(x) = 3^3 + 3 * 3^2 – 25 * 3 – 75

f(x) = -96

(not a factor)

c. x + 3

x = -3

Substitute x = 3 into the equation.

f(x) = (-3)^3 + 3 * (-3)^2 – 25 * (-3) – 75

f(x) = 0

(a factor)

d. x - 5

x = 5

Substitute x = 3 into the equation.

f(x) = 5^3 + 3 * 5^2 – 25 * 5 – 75

f(x) = 0

(a factor)

e. x + 5

x = - 5

Substitute x = 3 into the equation.

f(x) = (-5)^3 + 3 * (-5)^2 – 25 * (-5) – 75

f(x) = 0

(a factor)

1. Input

wel

Answer:

The equilibrium point represents the raising or lowering the price in response to changes in the supply or demand.

If the price of a good is above equilibrium, this means that the quantity of the good supplied exceeds the quantity of the good demanded.

If the quantity is below the equilibrium point, it will create a shortage. because the quantity supplied is less than quantity demanded.

Suppose that at a state college, a random sample of 41 students is drawn, and each of the 41 students in the sample is asked to

Answer:

The confidence interval for 90% confidence would be narrower than the 95% confidence

Step-by-step explanation:

From the question we are told that

The sample size is n = 41

For a 95% confidence the level of significance is $\alpha = [100 - 95]\% = 0.05$ and

the critical value of $\frac{\alpha }{2}$ is $Z_{\frac{\alpha }{2} } =Z_{\frac{0.05 }{2} }= 1.96$

For a 90% confidence the level of significance is $\alpha = [100 - 90]\% = 0.10$ and

the critical value of $\frac{\alpha }{2}$ is $Z_{\frac{\alpha }{2} } =Z_{\frac{0.10 }{2} }= 1.645$

So we see with decreasing confidence level the critical value decrease

Now the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }$

given that other values are constant and only $Z_{\frac{\alpha }{2} }$ is varying we have that

$E\ \ \alpha \ \ Z_{\frac{\alpha }{2} }$

Hence for reducing confidence level the margin of error will be reducing

The confidence interval is mathematically represented as

$\= x - E < \mu < \= x + E$

Now looking at the above formula and information that we have deduced so far we can infer that as the confidence level reduces , the critical value reduces, the margin of error reduces and the confidence interval becomes narrower
