The perimeter of the hexagon is 180 ft.

The area of the hexagon is 2338.3 ft

The perimeter of the polygon can be found as follows:

The polygon is a regular hexagon.

Therefore,

perimeter of the hexagon = 30 × 6 = 180 ft

Area of the hexagon = 3√3 / 2 × s²

The coordinates of B is (-2, 3).

In geometry, translation is the movement of a point or shape from one position to another.

Here, The translation from ΔABC to ΔA'B'C' is (x, y) → (x + a, y + b)

Now, given coordinate

A ≡ (5, 1)      ⇒       A' ≡ (6, -2)

                             A' ≡ (1+5, 1 - 3)

                      On comparing this coordinate with translation coordinate

                       (x + a, y + b), we get

                          a = 1 and b = -3

Now translation coordinates is (x + 1, y - 3),

Now, Another coordinate;

B' ≡ (-1, 0)                   and the coordinate of B ≡ (x, y)

B' ≡ (-2+1, 3-3)

On comparing this coordinate with translation coordinate (x + 1, y - 3), we get

x = -2 and y = 3

Thus, the coordinates of B is (-2, 3).

The standard deviation is 3.807.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

Given:

variance= 14.5

standard deviation = √variance

                               = √14.5

The dimensions of the circular cylinder of maximum volume inscribed in  sphere is r = 20.4 cm , h = 28.86 cm.

A sphere is a three dimensional round shaped figure , It has no vertices and the distance form the centre to any point on the sphere is same.

It is given that

A right circular cylinder is inscribed in a sphere

The circular cylinder has the maximum volume

Radius of the sphere is 25 cm.

Dimensions of the cylinder = ?

As it is a right cylinder.

The Pythagoras theorem can be applied

r² + (h/2)² = 25²

r² = 625 - h²/4

volume of the cylinder

=  πh(625 - h²/4)

= π(625 h - h³/4)

As the volume is maximum ,

so the derivative of the expression = 0

π(625 - 3h²/4) = 0

so h =  50 /√ 3

so r² = 625 - 2500 / (3 *4 )

r = 20.4 cm

h = 28.86 cm

Therefore the dimensions of the circular cylinder of maximum volume inscribed in a sphere is r = 20.4 cm , h = 28.86 cm.

The amount or the strength of force is called its magnitude.

Step-by-step explanation:

The amount or the strength of force is named magnitude.

Force is that the push or pull on an object with mass that causes it to alter its velocity. Force is an external agent capable of adjusting the state of rest or motion of a selected body. it's a magnitude and a direction.

The term which is true is magnitude. The magnitude of a force is expressed within the SI unit of force called Newton. 1 Newton is that the force which might make an object of 1 kilogram mass to  at a speed of 1 meter per second. Magnitude is essentially the most extent of size and also the direction of an object. Magnitude is employed as a typical think about vector and scalar quantities. Magnitude of earthquake is measured by Richter scale.

Answer:

[tex]\huge\boxed{\sf y = -2x - 3}[/tex]

Step-by-step explanation:

m = -2

y = mx + c

(x,y) = (-5,7)

So, x = -5, y = 7

To find c, Put the values of x, y and m in the slope-intercept form.

7 = (-2)(-5) + c

7 = 10 + c

7 - 10 = c

-3 = c

c = -3

Now, put the values of m and c in the slope intercept form.

y = -2x - 3

A) The number of cards that are in a complete deck of Set is; 81

B) The number of unique sets are; 36

a) We are given;

Number of shapes = 1, 2 or 3

Colour = Red, Purple or Green

Shape = Oval, Diamond or Squiggle

Shading = Hollow, Shaded or Striped

Now, since a set is formed by all 3 cards, then we can say that;

Number of cards in a complete deck of set = 3⁴ = 81 cards

(b) Let us first find all sets = 3² * 4 * 3 = 108.

Thus;

Unique sets = 108/3

= 36 unique sets.

(c) There are 3 ways to choose the number of the cards from the given order.  

For the second one, there 2 choices, and then there is only 1 choice.  Thus; Number of ways to choose the numbers = 3 * 2 * 1 = 6.  

For the other attributes;

Number of ways = 6 * 6 * 24 *6 ways.

Now, since the order of cards doesn't matter in a set, then the number of sets where all three cards are the same for exactly 0 attributes is;

(6 * 6 * 24 *6)/3! = 864 sets

(d) If all the colors are the same, then;

Number of sets = 6 * 24 * 6/3! = 144 sets.  

If all the numbers are the same, then there are 144 sets which is also same for shapes and shading. Thus;

The number of sets where all three cards are the same for exactly 1 attribute is; 4 * 144 = 576

(e) There are C(4, 2) = 6 ways of choosing two attributes.  

For each of the two attributes, there are 3 options.  

For the other two attributes, there are 3 ways of assigning the choices. Thus, number of sets = 6*3*3*3*3 = 486 sets.

(f) There are C(4,3) = 4 ways of choosing which attributes are the same.  There are 3*3*4 = 36 ways to assign which is which for each of these three attributes, and there are 4 ways to assign the choices for the fourth attribute. Thus;

The number of sets where all three cards are the same for exactly 3 attributes = 4*36*4 = 576 sets.

Answer:

The third answer is correct.

Step-by-step explanation:

Answer:

y = 20°

x = 35°

Explanation:

Equation's:

   1) 2y + x + 105° = 180°

   2) 3x + x + 2y = 180°

Make y subject in equation 2

3x + x + 2y = 180

4x + 2y = 180

2y = 180 - 4x

y = 90 - 2x

Insert this into equation 1

2(90 - 2x) + x + 105° = 180°

180 - 4x + x + 105 = 180

-3x = -105

x = 35°

Find value of y

y = 90 - 2x

y = 90 - 2(35)

y = 20°

Step-by-step explanation:

Using the normal distribution, it is found that there is a 0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for this problem are given as follows:

[tex]\mu = 23.8, \sigma = 6, n = 20, s = \frac{6}{\sqrt{20}} = 1.3416[/tex]

The probability that 20 customers will wait an average of less than 21 minutes to be seated is the p-value of Z when X = 21, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{21 - 23.8}{6}[/tex]

Z = -0.47

Z = -0.47 has a p-value of 0.3192.

0.3192 = 31.92% probability that 20 customers will wait an average of less than 21 minutes to be seated.
