Find the measure of one exterior angle of each regular polygon. Round to the nearest tenth if necessary
Answers
Answer:
40 degrees
Step-by-step explanation:
360/9=40
The solution is 40°
The measure of one exterior angle of a nonagon is is given by the equation A = 360°/9 and the measure of A is 40°
What is the sum of an exterior angle of a polygon?
The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. The sum of an interior angle and its corresponding exterior angle is always 180 degrees since they lie on the same straight line
Sum of exterior angles of a polygon = 360°
Measure of each exterior angle = 360° / N
where N is the number of sides
Given data ,
Let the measure of each exterior angle be = A
Let the number of sides of the polygon be = N
Now , the polygon is a nonagon
So , the number of sides N = 9
Now , The sum of exterior angles of a polygon is 360°
So ,
The measure of each exterior angle is given by the equation 360° / N where N is the number of sides
Substitute the value for N in the equation , we get
The measure of each exterior angle = 360°/9
The measure of each exterior angle = 40°
Therefore , the value of A is 40°
Hence , the measure of each exterior angle is 40°

According to a recent survey, 81 percent of adults in a certain state have graduated from high school. If 15 adults from the state are selected at random, what is the probability that 5 of them have not graduated from high school?
Answers
Answer:
0.090401
Step-by-step explanation:
Given that:
Probability of graduate = 81% = 0.81
P( not graduate) = p = (1 - 0.81) = 0.19
1 - p = 0.81
Using binomial distribution :
P(x = x) = nCx * p^x * 1-p^(n-x)
n = 15 ; x =5
P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)
P(x = 5) = 15C5 * 0.19^5 * 0.81^10
P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801
P(x = 5) = 0.090401
Answer:

We want to find the zeros of this polynomial:

Plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answers
Answer:
How do you find the zeros of a polynomial graphically?
Step-by-step explanation:
If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.

Using trigonometric ratios we know that:

To find the height, we will use sine.

Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary
This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.
You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other

Betsy buys three lamps and two end tables and pays $520. Her friend Tina buys two lamps
and RETURNS an end table and only pays $20. What do the lamps and end tables cost?
Answers
9514 1404 393
Answer:
lamp: $80end table: $140Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.

It takes Zion three times as long to paint a room as it does Sanjay. How long does it take each person by
himself if they can paint the room together in 30 minutes?
Answers
Answer:
It takes Sanjay 40 minutes and Zion 120 minutes
Step-by-step explanation:
If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes
Painting together, they spent 30 minutes
1/x + 1/3x = 1/30
4/3x = 1/30
4 * 30 = 3x * 1
120 = 3x
x = 120/3
x = 40 minutes
3x = 3 * 40 = 120 minutes
