Fine the measure of the angle formed by the radius and the side of a regular dodecagon.

Mathematics

Elden [556K]3 years ago

Answer:

Option D.75°

Step-by-step explanation:

we know that

The sum of the interior angles of a regular dodecagon is equal to

S=(n-2)*180

where

n is the number of sides

In this problem

n=12 sides

substitute

S=(12-2)*180

S=1,800\°

Find the measure of each interior angle

Divide the sum of the interior angles by the number of sides

1,800\°/12=150\°

The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle

therefore

150\°/2=75\°

I hope this helps you



f (x)=(x+2)^3/2


f'(x)=3/2. (x+2)^3/2-1


f'(x)=3/2 (x+2)^1/2

Prove that there is only one circle determined by three noncollinear points
tensa zangetsu [6.8K]

Answer:

O lies on the perpendicular bisector of AB. ... Then, O' will lie on the perpendicular bisector PQ and RS. We know that, two lines cannot intersect at more than one point, So O' must coincide with O. Hence, there is one and only one circle passing through three non collinear points

A researcher was testing the number of popcorn kernels that popped out of a mini bag of 100 kernels after being cooked for the s
Lelechka [254]

Answer:

The percentage of the bag that should have popped 96 kernels or more is 2.1%.

Step-by-step explanation:

The random variable <em>X</em> can be defined as the number of popcorn kernels that popped out of a mini bag.

The mean is, <em>μ</em> = 72 and the standard deviation is, <em>σ</em> = 12.

Assume that the population of the number of popcorn kernels that popped out of a mini bag follows a Normal distribution.

Compute the probability that a bag popped 96 kernels or more as follows:

Apply continuity correction:

P( X\geq 96)=P( X>96+0.50)

                 =P( X>96.50)\\=P(\frac{X-\mu}{\sigma}>\frac{96.50-72}{12})\\=P(Z>2.04)\\=1-P(Z

*Use a <em>z</em>-table.

The probability that a bag popped 96 kernels or more is 0.021.

The percentage is, 0.021 × 100 = 2.1%.

Thus, the percentage of the bag that should have popped 96 kernels or more is 2.1%.

What value of x is in the solution set of 9(2x + 1) &lt; 9x - 18?
Alex17521 [72]

Answer:

b. -3

Step-by-step explanation:

9(2x+1) < 9x-18

(distribute the 9)

18x+9 <9x-18

(subtract 9 from both sides)

18x<9x-27

(subtract 9x from both sides)

9x<-27

(divide both sides by 9)

x<-3
