This gives us a dendrogram with three levels, where the first level has two clusters {{7,10},{20,28}} and {35}, the second level has two clusters {{7,10,20,28},35}, and the third level has only one cluster {{7,10,20,28,35}}.

What is a sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

To perform hierarchical clustering using single linkage, we start by treating each point as its own cluster, and then iteratively merge the two closest clusters until only one cluster remains. We use the single linkage method, which defines the distance between two clusters as the minimum distance between any two points in the clusters.

First, we calculate the pairwise distances between each point:

  7    10   20   28   35

7   -    3    13   21   28

10  3    -    10   18   25

20  13   10   -    8    15

28  21   18   8    -    7

35  28   25   15   7    -

Next, we find the two closest points/clusters and merge them:

  7,10  20   28   35

7,10  -    10   18   25

20    10   -    8    15

28    18   8    -    7

35    25   15   7    -

The closest points/clusters are 7 and 10, so we merge them to form a new cluster {7,10}.

  7,10  20,28  35

7,10  -    18     25

20,28 18   -      7

35    25   7      -

The closest points/clusters are now {20,28} and 35, so we merge them to form a new cluster {{20,28},35}.

 7,10  {20,28,35}

7,10  -    7

{20,28,35} 7    -

The closest points/clusters are now {7,10} and {{20,28},35}, so we merge them to form a new cluster {{{7,10},{20,28}},35}.

Hence, This gives us a dendrogram with three levels, where the first level has two clusters {{7,10},{20,28}} and {35}, the second level has two clusters {{7,10,20,28},35}, and the third level has only one cluster {{7,10,20,28,35}}.

The dendrogram can be visualized as in the attached image.

Step-by-step explanation:

The paper clip costs $0.05 and the folder Costs $1.00 more, which is $1.05. Together, they add up to the total of $1.10.

Let's solve this problem step by step:

Let's assume the cost of the paper clip is x dollars.

According to the information given, the folder costs $1.00 more than the paper clip, so the cost of the folder would be (x + $1.00).

The total cost of the folder and the paper clip is $1.10, so we can write the equation:

x + (x + $1.00) = $1.10

Combining like terms, we have:

2x + $1.00 = $1.10

Subtracting $1.00 from both sides of the equation, we get:

2x = $0.10

Dividing both sides by 2, we find the value of x:

x = $0.10 / 2

x = $0.05

Therefore, the paper clip costs $0.05.

In summary, the paper clip costs $0.05 and the folder costs $1.00 more, which is $1.05. Together, they add up to the total of $1.10.

Answer:

6 units

Step-by-step explanation:

since the y- coordinates of both points are 7 then the horizontal distance between the points is the absolute value of the difference in the x- coordinates , that is

d = | 9 - 3 | = | 6 | = 6 units , or

d = | 3 - 9 | = | - 6 | = 6 units

Answer:

The argument of the logarithmic function should be greater than zero.

Thus, for y = log(-x + 3) - 1 to be real-valued, we need:

-x + 3 > 0

or

x < 3

So, the domain of the function is all real numbers less than 3.

To find the range, let's consider the behavior of the logarithmic function.

As x approaches 3 from the left, the argument of the logarithm approaches zero from the negative side, which means the logarithm approaches negative infinity.

As x approaches negative infinity, the argument of the logarithm becomes very large and negative, which means the logarithm approaches negative infinity.

Therefore, the range of the function y = log(-x + 3) - 1 is all real numbers.

The volume of the pyramid is approximately 574,533.33 cubic meters.

To find the volume of a pyramid, you use the formula: V = (1/3) × base area × height, where B is the area of the base and h is the height of the pyramid.

Given that the side length of the square base is 140 m and the height is 91 m.

Since the base of the pyramid is a square with a side length of 140 m, we can find its area by multiplying the side lengths: B = 140m x 140m = 19,600 square meters.
By calculating this expression, you'll find the volume of the pyramid.

Now we can plug in the values for B and h into the formula: V = (1/3)(19,600 square meters)(91 meters) = 574,533.33 cubic meters.

Step-by-step explanation:

According to the general equation for conditional probability, the conditional probability of event A given event B is calculated as

P(A|B) = 24/49

Given that P(A∩B) = 3/7 and P(B) = 7/8, we can substitute these values into the equation:

P(A|B) = (3/7) / (7/8)

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:

P(A|B) = (3/7) * (8/7)

Simplifying the expression, we have:

P(A|B) = 24/49

Therefore, the probability of event A given event B is 24/49.

We need 0.75 litres of paint to cover a 15m2 wall, assuming the paint has a coverage of 20m2 per litre.

To cover a 15m2 wall with a paint that has a coverage of 20m2 per litre, we need 0.75 litres of paint.

We can find this by dividing the area to be covered (15m2) by the coverage of the paint per litre (20m2/litre):

15m2 ÷ 20m2/litre = 0.75 litres

Therefore, we need 0.75 litres of paint to cover a 15m2 wall, assuming the paint has a coverage of 20m2 per litre.

The mean and median number of hours Rashawn spend in listening to music is 5.7 hours and 6 hours, under the condition that there were 6 days in which Rashawn listened to music.

Now to evaluate the mean number of hours Rashawn listened to music for the 6 days, we have  to sum up all the hours and divide by the number of days.

Then, total number of hours Rashawn heard music for 6 days is

= 6 + 5 + 5 + 6 + 5 + 7

= 34 hours

Mean  = Total number of hours / Number of days

= 34 / 6

= 5.7 hours

Now,

For evaluating  the median number of hours Rashawn heard  music in the interval of  6 days

We have to set the number in the order of smallest to largest

Answer:

254 cm² (to 3 s.f.)

Step-by-step explanation:

Area of shaded region

= area of large circle -area of smaller circle

\(\boxed{area \: of \: circle = \pi {r}^{2} }\)

Radius of large circle= 15cm

Radius of smaller circle= 12cm

Area of shaded region

= π(15²) -π(12²)

The measure of the angles are: K, L, C, N, O G = -3/4, 65, 8 40.4, 89 and 44 respectively

To determine K

9x + 2 = 23 + 5x -1

9x -5x = -1 +2

4x = -3Making x the subject we have

x= -3/4

To find the value of L

Let angle L be x

x + 65 = 130

x=130-65

That is x = 65

To find the m<C

4x + 7 = 3x + 15

Collecting like terms

4x - 3x = 15-7

Making x the subject of the relation we have

x=8

To find the m<N

7x + 6x - 1 = 90

13x = 89

x=89/13

x= 6.9

Substitute x = 6.9 in 6x -1

6(6.9) -1

m<L = 40.4

To find the m<O

5x - 11 = 4x +9

5x-4x = 9 +11

x=20

By substitution in 4x +9 we have

4(20) +9

80+9

m<S = 89

In parallelogram ABCD, ∠b = 55°; ∠d = 55. So, the correct answer is (a).

We know that opposite angles of a parallelogram are congruent. In another words, opposite angles of  parallelogram are equal. Therefore, we equate the angle B and angle D to each other and solve.

angle B = angle D

2n + 15 = 3n - 15

n = 30

The value of n is 30.

Now we can find the measures of angles B and D:

angle B = 2n + 15 = 2(30) + 15 = 75 degrees

angle D = 3n - 15 = 3(30) - 15 = 75 degrees

. The quadratic approximation of the function f(x) = (1 + x)^k at x = 0 using Taylor's formula with n = 2 is Q(x) = 1 + kx + (k(k-1)/2)\(x^{2}\)

To find the quadratic approximation, we need to use Taylor's formula with n = 2. The formula for the quadratic approximation Q(x) is given by:

Q(x) = f(0) + f'(0)x + (1/2)f''(0)\(x^{2}\)

Since f(x) =\((1 + x)^{k}\), we first find the derivatives of f(x) up to the second order. Taking the derivatives, we have:

f'(x) = k\((1 + x)^{k-1}\)

f''(x) = k(k-1)\((1 + x)^{k-2}\)

Now, we substitute these derivatives into the quadratic approximation formula:

Q(x) = f(0) + f'(0)x + (1/2)f''(0)\(x^{2}\)

At x = 0, we have:

Q(0) = f(0) + f'(0)(0) + (1/2)×0
