Answer:  s​ = ​P​ ÷ 6

Step-by-step explanation:

The simplest, and by far most common, way of finding the length of a regular hexagon's sides is using the following formula: ​s​ = ​P​ ÷ 6, where ​P​ is the perimeter of the hexagon, and ​s​ is the length of any one of its sides.

Answer:

All the interior angles measure 120°. All the exterior angles measure 60°. Since all angles are equal in a regular hexagon, each angle is 120o and the sum of all the interior angles is 720o.

Answer:

x = 62

Step-by-step explanation:

Recall the properties of parallel lines with transversals. Vertical angles are congruent so the angle across from 118° is also 118°.

Recall the consecutive interior angles theorem. If two angles are on the same side of the transversal and are between the two parallel lines, then their measures add up to 180°. 180° - 118° = 62°.

Therefore, x = 62.

uhhhh

Answer:
b = 21°
c = 159°

Step-by-step explanation:

To solve for B we have to know that the opposite angle is the same. So 21° is the same as angle b.

To solve for C we have to know that a line adds up to 180°. So 21° plus c = 180

To find this we do 180 - 21 = 159.

I hope this helps you :D

Answer:

B = 21

C = 159

Step-by-step explanation:

As we are given 21 degrees as one of the angles, we can also notice that both lines are straight, so they are both adding up to an angle of 180 each.

To find C, we can use this equation:

C + 21 = 180

C = 180-21

C = 159

To find B, we can use this equation:

B + C = 180

Plug in C:

B + 159 = 180

B = 180-159

B = 21

Answer:

Step-by-step explanation:

A = πr^2

(153.86) = (3.14) r^2

Divide 3.14 on both sides.

49 = r^2

Square root both sides.

7 = r

D = 2r

D = 2(7)

D = 14

The diameter of the circle is 14 square meters.

Answer:

14 meters²

Step-by-step explanation:

Since the formula to find the diameter is d = 2r, we need to first find the radius, which can be r = square root of Aπ over π if we take the formula for the area of a circle and isolate the radius. After simplifying r = square root of 153.86π over π to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!

9.23 is greater than 9.15

9.23 > 9.15

The statements that are true regarding the measures of center and variability of these data sets include:

A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:

Mean, \bar{x} = ∑x/n

Where:

Based on the information provided, we have:

Mean of Yard Works = (7+9+7+12+5)/5

Mean of Yard Works = 8.

Mean of Grow Station = (9+11+6+12+7)/5

Mean of Grow Station = 9.

Range is the difference between the maximum and minimum numbers;

Range of Yard Works = 12 - 5

Range of Yard Works = 7.

Range of Grow Station = 12 - 6

Range of Grow Station = 6.

Mean absolute deviation is given by;

MAD = 1/n ∑|x - μ|

Where:

Mean absolute deviation of Yard Works = 2

Mean absolute deviation of Grow Station = 2.

Answer:

{6, 8, 10}

Step-by-step explanation:

n + 5 > 10

n > 5

Only numbers greater than 5 satisfy the inequality.

The answer is a set that only contains numbers greater than 5.

Answer: {6, 8, 10}

The values that satisfies the condition n+5>10 among {2,4,6,8,10} is

{6,8,10}

let  check the every value of {2,4,6,8,10} satisfies the condition n+5>10

let n=2

= n+5 = 2+5 = 7

7!>10  

so 2 does not satisfies the condition

let  n=4

 = 4+5 = 9

9!>10

lly 4 does not satisfies the condition

let n= 6

=n+5 = 6+5 = 11

11>10 satisfies the condition

let n= 8

=n+5 = 8+5 = 13

13>10 satisfies the condition

let n= 10

=n+5 = 10+5 = 15

15>10 satisfies the condition

only {6,8,10} satisfies the given condition

Answer:

The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}

The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.

Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.

Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.

Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.

Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.

Answer:

-1 ¹/₉

Step-by-step explanation:

Firstly, let:

x = -1.111...

This means:
10x = -11.111...

Then:

10x - x = -11.111... - (-1.111...)

9x = -11.111... + 1.111...

9x = -10

x = -¹⁰/₉

x = -(⁹/₉ + ¹/₉)

x = -1 ¹/₉

(2/3)*75 = $50
