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

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=83°, and RS = 7 feet. Find the length of SQ to the nearest tenth of a foot.
Simora [160]

Answer:

x ~0.9

Step-by-step explanation:

To solve for (x) in the given right triangle, use the trigonometric ratios, which are the following,

sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}

Each of the sides of a triangle is named with respect to the given angle. In this problem, one is given the side opposite to the given angle, and the side adjacent to it. Use the ratio of tangent (tan) to solve for the unknown side.

tan(83)=\frac{7}{x}

Manipulate the equation so that it is solved for (x),

x=\frac{7}{tan(83)}

x ~ 0.859

How is a recursive sequence different from an arithmetic or geometric sequence?
Andre45 [30]
 <span>An arithmetic or geometric is a recursive sequence, because you can write it in terms of the previous term adding or multiplying some constant respectively. A recursive sequence however, is not always arithmetic or geometric.</span>

Evolution the expression when a=–3 and x=3 5a–x
Dafna11 [192]

It's a good idea to get into the habit of using <u>parentheses</u> when substituting numbers in for variables.

Since <em>a = -3</em> and <em>x = 3</em>, 5a - x is 5(-3) - (3).

5(-3) is -15 and we have (-15) - 3 which simplifies to -18.
