Answer:
[tex]l = 3.66[/tex]
Step-by-step explanation:
Given
[tex]r =1[/tex]
[tex]\theta = \frac{7\pi}{6}[/tex]
Required
The arc length (l)
This is calculated as:
[tex]l= r\theta[/tex]
So, we have:
[tex]l = 1 * \frac{7\pi}{6}[/tex]
[tex]l = \frac{7\pi}{6}[/tex]
So, we have:
[tex]l = \frac{7*3.14}{6}[/tex]
[tex]l = 3.66[/tex]
None of the options is correct

The sum of the interior angles of the 10-sided polygon on the left is °
Answer:
1440 it is right because
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°
= 1440°
Answer:
The answer is indeed 1440.
Step-by-step explanation:
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
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.

Determine the equation of the line parallel to the line y=34x+2
y=3/4x+2 that passes through the point (4, -3).
Answer:
y = 34x - 139 (y = 34x + 2)
y = [tex]\frac{3}{4}[/tex]x - 6 (y = 3/4x +2)
Step-by-step explanation:
(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
What is the slope of the line? PLEASE PLEASE HELP FAST!
Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line
m = [tex]\frac{2-0}{1-0}[/tex] = [tex]\frac{2}{1}[/tex] = 2

[tex]16\sqrt{3}\:\mathrm{units^2}[/tex]
Step-by-step explanation:
The area of an equilateral triangle with side length [tex]s[/tex] is equal to [tex]\frac{\sqrt{3}}{4}s^2[/tex]. Since the perimeter is 24 units and there are three equal sides to an equilateral triangle, each side is [tex]24\div 3=8[/tex] units.
Substituting in this value, we get:
[tex]\frac{\sqrt{3}}{4}8^2=\frac{64\sqrt{3}}{4}=\boxed{16\sqrt{3}}[/tex]

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
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.
