D. f(x)= x*-9x^o+2x^2-4x+10

5 0

Answer:

Step-by-step explanation:

None of these are in standard form.  In standard form the powers of x are arranged in descending order, which is not the case here.  Also, all terms containing the same power of x (such as x - 4x - 9x) should be simplified into ONE term with ONE coefficient.

Which of the following p values will lead us to reject the null hypothesis if the level of significance equals .05?
V125BC [204]

Answer:

So then our significance level is \alpha=0.05 and we need to remember these two conditions:

1) If the p value p_v we have enough evidence to reject the null hypothesis at the significance level given

2) If the p value p_v \geq \alpha we have enough evidence to FAIL reject the null hypothesis at the significance level given

And baed on the options we see that the only possibility would be:

d. 0.015

Step-by-step explanation:

We want to know for which value we would REJECT the null hypothesis.

So then our significance level is \alpha=0.05 and we need to remember these two conditions:

1) If the p value p_v we have enough evidence to reject the null hypothesis at the significance level given

2) If the p value p_v \geq \alpha we have enough evidence to FAIL reject the null hypothesis at the significance level given

The circumference of a circle is 6 inches. What is the area of the circle?
Lubov Fominskaja [6]

Answer:

(B) 9π in²

Step-by-step explanation:

I’m going to assume that by 6 inches you meant 6π inches.

If the circumference of a circle is 6π inches, then it’s radius will be half of 6 (because the circumference of a circle is 2\pi r).

6\div2=3

So the radius is 3.

Now that we know the radius, we can find the area by using the equation \pi r^2.

\pi 3^2\\\pi9\\9\pi

Hope this helped!
