Will give 5 stars to first correct answer! Thanks!

What is the equation of this line? o y = -1/4x o y = – 4x o y = 1/4x O y = 4x

Kitty [74]

Answer:

Step-by-step explanation:

Look at the line. See where it attaches at one point and look where it attaches to another, for example, in this expression, it attaches to (0,0) and (4,-1). Then do rise over run, or y over x. This means to do this- y2 - y1 divided by x2 - x1. First, do -1 - 0. Its a double negative, so it becomes positive, thus making it 1 - 0, which is still 1. Then do 4 - 0, which is still 4. Divide 1 by 4, turn it to a fraction, and boom, you've got 1/4x.

Hope this helps!!!!![?][?][?]

A hotel wants to know if there's a relationship between gender and the way customers make room reservations. A manager takes a r

padilas [110]

Answer:

Step-by-step explanation:

Here,

H_o: The way of reservation is independent of gender.

H_a: The way of reservation is not independent of gender.

We use a chi square test because we can calculate the expected frequencies for this chart.

Doing an Expected Value Chart,

33.7625 9.7125 30.525

39.2375 11.2875 35.475

Using chi^2 = Sum[(O - E)^2/E],

chi^2 = 4.482385929

With df = (a - 1)(b - 1), where a and b are the number of categories of each variable,

a = 3

b = 2

df = 2

Thus, the critical value is

significance level = 0.05

chi^2(critical) = 5.991464547

Also, the p value is

P = 0.106331579

Thus, comparing chi^2 and chi^2(critical) [or, p and significance level], we FAIL TO REJECT THE NULL HYPOTHESIS.

Thus, there is no significant evidence that the way of reservation is dependent of gender. [CONCLUSION]

2) The triangles are similar. Find the similarity ratio of the first triangle to the 1 point

USPshnik [31]

Given:

Triangles FRI and DAY are similar.

To find:

Similarity ratio

Solution:

If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.

Here, FR and DA are corresponding sides.

$$\Rightarrow \frac{FR}{DA} =\frac{4}{6}$

Cancel the common factors of 4 and 6, we get

$$\Rightarrow \frac{FR}{DA} =\frac{2}{3}$

⇒ FR : DA = 2 : 3

⇒ ΔFRI : ΔDAY = 2 : 3

Similarity ratio of the first triangle to the second triangle is 2 : 3.

Evaluate the expression. Choose the best answer. <img src="https://tex.z-dn.net/?f=8%5EP4" id="TexFormu

Morgarella [4.7K]

N P r = (n!)/((n-r)!)
8 P 4 = (8!)/((8-4)!)
8 P 4 = (8!)/(4!)
8 P 4 = (8*7*6*5*4!)/(4!)
8 P 4 = 8*7*6*5
8 P 4 = 1680

The final answer is 1680
