Answer:

I think it's C.

After answering the question provided, we can predict that the result will be as in the triangle by Pythagorean theorem = [tex]\sqrt{12^2 - 4^2}[/tex] => N = [tex]\sqrt{144 - 16}[/tex] => n = [tex]\sqrt{132}[/tex]

A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.

by Pythagorean theorem

n = [tex]\sqrt{12^2 - 4^2}[/tex]

N = [tex]\sqrt{144 - 16}[/tex]

n = [tex]\sqrt{132}[/tex]

Answer:

n = 10

Step-by-step explanation:

n is the altitude of the right triangle.

Apply the right triangle altitude theorem/geometric mean theorem to find n.

Which is:

h = √(xy)

Where,

h = n =?

x = 5

y = 20

Plug in the value into the equation

n = √(20*5)

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

The cube root function , has no domain restrictions. The domain of the cube root function is all real numbers, or ℝ .

The domain of a function is the complete set of possible values of the independent variable.

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero.

The number under a square root sign must be positive in this section.

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Domain: (- ∞ , ∞) , {x | x ∈ [tex]\mathbb{R}[/tex]}

Hence, The domain of the cube root function is all real numbers, or ℝ .

Answer:

The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.

Step-by-step explanation:

A machine, when working properly, produces 5% or less defective items.

This means that the null hypothesis is:

[tex]H_0: p \leq 0.05[/tex]

Test if the percentage of defective items produced by this machine is greater than 5%.

This means that the alternate hypothesis is:

[tex]H_a: p > 0.05[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.05 is tested at the null hypothesis:

This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]

A random sample of 300 items taken from the production line contained 27 defective items.

This means that [tex]n = 300, X = \frac{27}{300} = 0.09[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.09 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{300}}}[/tex]

[tex]z = 3.18[/tex]

Pvalue of the test:

Testing if the mean is greater than a value, which means that the pvalue of the test is 1 subtracted by the pvalue of Z = 3.18, which is the probability of a finding a sample proportion of 0.09 or higher.

Looking at the Z-table, Z = 3.18 has a pvalue of 0.9993

1 - 0.9993 = 0.0007

The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.

Answer:

z + 15

Step-by-step explanation:

In this example, it's not an equation (it doesn't "equal" anything), just an expression. We cannot combine z with the actual numbers. It is a variable, so it could be combined with other terms including z, like if it said 2z + z + 5 x 3.

The only thing you can do with your expression is "combine like terms" by multiplying 5 and 3 to get 15.

Find the Reference Angle (17pi)/10

17π1017π10

Since the angle 17π/ 10 is in the fourth quadrant, subtract 17π/10 from2π.

2π−17π/10

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Angles are considered to be in standard position if the initial side is on the positive x-axis and the vertex at the (0,0) point of the Cartesian plane. All angles generated that share the same terminal side are coterminal angles. These are angles that have differences of multiples of 360n or n2pi where n is an integer.

A coterminal angle is found by simply adding or subtracting 360 and its multiples.

The coterminal angles of 20 degrees for example are 20 + 360 = 380 or 20 - 360 = -340. This may continue by adding or subtracting 360 each time.

To get coterminal angles, you simply have to add or subtract 2[tex]\pi[/tex].

According to this problem,

We are looking for a coterminal angle that is between 0 to 2[tex]\pi[/tex], so we will add [tex]2\pi \ to \ \frac{-17\pi }{10}[/tex].

= [tex]\frac{-17\pi }{10} +\frac{20\pi }{10}[/tex]

= [tex]\frac{-17\pi +20\pi }{10}[/tex]

= [tex]\frac{3\pi }{10}[/tex]

Hence,

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].
