Step-by-step explanation:

El plano de coordenadas se desarrolló hace cientos de años y fue refinado por el matemático Francés René Descartes. En su honor, se le conoce también como sistema de coordenadas Cartesianas. El plano de coordenadas puede usarse para graficar puntos y rectas.

Step-by-step explanation:

Decagon is a 10-sided polygon.

Formula to find the sum of interior angles of a n-sided polygon is  

=  (n - 2) ⋅ 180°

By using the formula,  sum of the interior angles of the given decagon (10-sided polygon) is  

=  (10 - 2) ⋅ 180°

=  8 ⋅ 180°

A school administrator claims that 85% of the students at his large school plan to attend college after graduation. The statistics teacher at this school selects a random sample of 50 students from this school and finds that 76% of them plan to attend college after graduation. The administrator would like to know if the data provide convincing evidence that the true proportion of all students from this school who plan to attend college after graduation is less than 85%. What are the values of the test statistic and P-value for this test?

Find the z-table here.

z = –1.78, P-value = 0. 0375
z = –1.78, P-value = 0. 0750
z = 1.78, P-value = 0.0375
z = 1.78, P-value = 0. 0750

Answers

Answer:

The first where z = -1.78 and p-value = 0.0375 would be the correct answer

Hope it helps

Using the z-distribution, it is found that the test statistic and the p-value of the test are given as follows:

z = –1.78, P-value = 0.0375.

What are the hypothesis tested?

At the null hypothesis, it is tested if the proportion is of 85%, that is:

[tex]H_0: p = 0.85[/tex]

At the alternative hypothesis, it is tested if it is less than that, hence:

[tex]H_1: p < 0.85[/tex].

What are the test statistic and the p-value?

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.

In this problem, we have that the parameters are given as follows:

[tex]n = 50, \overline{p} = 0.76, p = 0.85[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.76 - 0.85}{\sqrt{\frac{0.85(0.15)}{50}}}[/tex]

z = -1.78.

Using a z-distribution calculator, considering that we have a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.0375.

matthew lives 6 miles east of the school drew lives 8 miles north of the school. what is the shortest distance between the two houses? A. Two miles b. 10 miles c. 100 miles d. 4 miles

Answers

Answer:

Step-by-step explanation:

2miles

The required shortest between the two houses is given as 10 miles. Option B is correct.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.

Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.

Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,

x = √[8² + 6²]
x = √[100]
x = 10 miles

Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.

Answers

Answer:

1200

Step-by-step explanation:

Step 1 convert pounds to ounces

1 pound = 16 ounces

So to convert pounds to ounces we multiply by 16

1500 * 16 = 24000

So there are 24000 ounces in 1500 pounds

Step 2 Find how many 20 ounce containers he can fill.

To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20

So answer = 24000/20

24000 / 20 = 1200

Therefore he can fill 1200 20 - ounce containers
