Step-by-step explanation:

Marked down 25% means it is now worth 75% of original value.

0.75*39.59 = $29.69

please give thanks by clicking the heart buton :) happy holidays

Answer:

$29.70

Step-by-step explanation:

$39.59 / 4 = 9.8975.  Round up to 9.90

$39.59 - $9.90 = $29.69

Answer:

[tex]t _{critical} = 1.760[/tex]

t = 2.2450

d. 0.264

Step-by-step explanation:

The null hypothesis is:

[tex]H_o: \mu_1 - \mu_2 = 0[/tex]

Alternative hypothesis;

[tex]H_a : \mu_1 - \mu_2 > 0\\[/tex]

The pooled variance t-Test would have been determined if the population variance are the same.

[tex]S_p^2 = \dfrac{(n_1-1)S_1^2+(n_2-1)S^2_2}{(n_1-1)+(n_2-1)}[/tex]

[tex]S_p^2 = \dfrac{(8-1)2.507^2+(8-1)2.8282^2}{(8-1)+(8-1)}[/tex]

[tex]S_p^2 = 7.14[/tex]

The t-test statistics can be computed as:

[tex]t= \dfrac{(x_1-x_2)-(\mu_1 - \mu_2)}{\sqrt{Sp^2 ( \dfrac{1}{n} +\dfrac{1}{n_2})}}[/tex]

[tex]t= \dfrac{(9-6)-0}{\sqrt{7.14 ( \dfrac{1}{8} +\dfrac{1}{8})}}[/tex]

[tex]t= \dfrac{3}{1.336}[/tex]

t = 2.2450

Degree of freedom [tex]df = (n_1 -1) + ( n_2 +1 )[/tex]

df = (8-1)+(8-1)

df = 7 + 7

df = 14

At df = 14 and ∝ = 0.05;

[tex]t _{critical} = 1.760[/tex]

Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.

Conclusion: We reject [tex]H_o[/tex] and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.

To calculate r²

The percentage of the variance is;

[tex]r^2 = \dfrac{t^2}{t^2 + df}[/tex]

[tex]r^2 = \dfrac{2.2450^2}{2.2450^2 + 14}[/tex]

[tex]r^2 = \dfrac{5.040025}{5.040025+ 14}[/tex]

[tex]r^2 = 0.2647[/tex]

4. x=

Answer:

1.)111

2.)69

3.)60

4.)60

5.)51

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

From the question we have

[tex]m = \frac{5 - 2}{1 - 2} = - \frac{3}{1} = - 3 \\ [/tex]

We have the final answer as

Step-by-step explanation:

= 1.15 / 10⁵

115/10000000

0.0000115

is the correct answer

We can find a formula for nth term of the given sequence as follows:

1, 5, 12, 22, 35

The 1st differences between terms:

4, 7, 10, 13

The 2nd differences :

3, 3, 3

Since it takes two rounds of differences to arrive at a constant difference between terms, the nth term will be a 2nd degree polynomial of the form: [tex]a n^2 + b n + c[/tex], where c is a constant. The coefficients a, b, and the constant c can be found.

We can form the following 3 equations with 3 unknowns a, b, c:

[tex]1 = a\cdot1^2 + b\cdot1 + c\\5 = \cdot2^2 + b\cdot2 + c\\12 = a\cdot3^2 + b\cdot3 + c[/tex]

Solving for a, b, c, we get:

a = 3/2, b = -1/2, c = 0

Therefore, the nth term of the given sequence is:

[tex]\boxed{ a_n = \dfrac{3}{2}n^2- \dfrac{1}{2} n}[/tex]

Explanation

What is my perfect crime? I break into Tiffany's at midnight. Do I go for the vault? No, I go for the chandelier. It's priceless. As I'm taking it down, a woman catches me. She tells me to stop. It's her father's business. She's Tiffany. I say no. We make love all night. In the morning, the cops come and I escape in one of their uniforms. I tell her to meet me in Mexico, but I go to Canada. I don't trust her. Besides, I like the cold. Thirty years later, I get a postcard. I have a son and he's the chief of police. This is where the story gets interesting. I tell Tiffany to meet me in Paris by the Trocadero. She's been waiting for me all these years. She's never taken another lover. I don't care. I don't show up. I go to Berlin. That's where I stashed the chandelier.

Answer:

False

Step-by-step explanation:

2x + y = 0

Try (1, -2)

2(1) + (-2) = 0

2 + (-2) = 0

0 = 0

The solution works on the first equation.

-x + 2y = 5

-(1) + 2(-2) = 5

-1 - 4 = 5

-5 = 5

The solution does not work in the second equation.

Answer:

The table in blue

Step-by-step explanation:

Answer:

x=65, y=60

Step-by-step explanation:

x=65--->corrosponding angles with the triangle

x+y+55=180--->linear pair

(65)+y+55=180

y=60

Answer:

x=65 y=60

Step-by-step explanation:

Well, divide the hypotenuse between two triangles added onto the square root of the divisions between Mars and Pluto and we can derive the positive neutrons of the seventeenth quadratic of the Einstein constant equation.

or, know that x=65 due to it being on a parallel line to it, then due to their being 360 degrees around a point, 65+65+55+55=240, 360-240=120, then divide that by two to get it at y.
