Step-by-step explanation:

In the provided problem of collection survay data the researchers use the Cluster Analysis data analysis techniques.

Cluster analysis is a statistical technique for processing data. It works by organizing items into groups or clusters based on how closely related they are.

Cluster analysis, similar to reduced-space analysis (factor analysis), deals with data matrices in which the variables have not been previously split into reference and prediction subsets. The goal of cluster analysis is to find similar groups of subjects. Here, “similarity” between each pair of subjects means a global measure of the entire set of traits.

The most common use of cluster analysis is classification. Subjects are divided into groups such that each subject is more similar to other subjects within that group than subjects outside the group.

Cluster analysis used in following areas

In the context of market research, this can be used to identify categories such as age ranges, income ranges, urban, rural, or suburban locations.

Marketing can use cluster analysis for audience segmentation to target different customer groups with the most relevant messages.

Answer: $28.89

Step-by-step explanation: 2% of 1,444.50 is $28.89

Heidi earned $30 in commission.

The amount of money that the store made from Heidi's sales is equal to $720.

In this exercise, you're required to determine the amount of money earned by the salesperson as commission based on the price at which she sold a jewelry.

Mathematically, the amount of commission earned on the sales of a product can be calculated by using this mathematical expression:

Commission = Percent commission × Sales price

Given the following data:

Percent commission = 4%

Sales price = $750.

Substituting the given parameters into the formula, we have;

Commission = 4/100 × 750

Commission = 0.04 × 750

Commission = $30.

Next, we would determine the amount of money that the store made from her sales:

Sales = $750 - $30.

The equation to represent the situation is y = 15 + 30x.

The number of hours Sophia used for the guitar training after paying 75 dollars is 2 hours.

Sophia takes guitar lessons at home every Sunday. Her instructor charges $15 to cover home visit costs, and $30 per hour of training. One Sunday, Sophia's mother pays the instructor $75 for the guitar lessons.

The equation that can be used to represent the given situation is as follows:

let

x = number of hours used for the training

y = total cost

Therefore,

y = 15 + 30x

Now, Sophia's mother spent 75 dollars for her daughters training. Let's find the hours Sophia used.

Therefore,

75 = 15 + 30x

75 - 15 = 30x

60 = 30x

Perimeter of Rectangle could be considered as one of the important formulae of the rectangle. It is the total distance covered by the rectangle around its outside. A rectangle is a quadrilateral that has two pairs of parallel sides equal and all the four angles at the vertices are right angles.

The formula of perimeter of a rectangle is given as

P = 2(L + W)

But the width the rectangle is 6 feet more than half it's length.

W = 6 + 1/2L

If the perimeter is 313 times the length;

P = 2(L + W)

P = 2(L + 6 + 1/2L)

But P = 313L

313L = 2(L + 6 + 1/2L)

313L = 2L + 12 + L

313L = 3L + 12

310L = 12

L = 12 / 310

L = 0.039 ft

The length of rectangle is 0.039ft

The width of the rectangle is 6 + 1/2(0.039) = 6.0195ft

The perimeter of the rectangle = 2(L + w)

Perimeter = 2 (0.039 + 6.0195)

Perimeter = 12.117ft

The area of the rectangle is L * w

A = L * W = 0.039 * 6.0195

A = 0.234ft^2

The equation which is correct is :

n + q = 104

Since we have given that:

Number of nickels and quarters = 104

Total amount from them = $22

Let the number of nickels be 'n'

Let the quarters be 'q'

So, the equation will be

n + q = 104           -------------------------------------------- (1)

Since we know that

value of nickels = 0.05 dollars

Value of quarters = 0.25 dollars

So, the equation will be

0.05n + 0.25q = $22       ------------------------------------ (2)

So, there are two system of linear equation can be used to find the number of nickels and the number of quarters. i.e.

n + q = 104

0.05n + 0.25q = $22

Using elimination we can find the value of n and q :

0.05( n + q =104 )

⇒0.05n+0.05q=5.2-----------(3)

Now, from equation (2) and (3), we get,

0.05 n + 0.05q = 5.2

0.05 n + 0.25q = 22

(-)       (-)           (-)

------------------------------------

0          + 0.2q = 16.8

q = 16.8 ÷ 0.2

q = 84

Putting the value of q = 84 in equation (1),

   n + q = 104

2nd box:  [tex]\boldsymbol{90}[/tex]

3rd box:  [tex]\boldsymbol{\text{m}\angle 2 = \text{m}\angle 3}[/tex]

===============================================

Explanation:

Complementary angles form a corner. Note that "complementary" and "corner" both start with "C" to help remember the rule.

By "corner", I refer to a 90 degree angle.

Since [tex]\angle 1\text{ and } \angle 2[/tex] are complementary, we know that [tex]\text{m}\angle 1+\text{m}\angle 2 = 90[/tex] simply by the definition of what it means to be complementary.

---------------

Through similar logic, [tex]\angle 1\text{ and } \angle 3[/tex] are complementary which means [tex]\text{m}\angle 1+\text{m}\angle3 = 90[/tex]

We can then equate the left hand sides (LHS) of both equations since both LHS expressions equal 90. This is an example of the substitution property in action.

That's how we end up with [tex]\text{m}\angle 1+\text{m}\angle 2 = \text{m}\angle 1+\text{m}\angle 3[/tex]

After this point, subtract [tex]\text{m}\angle1[/tex] from both sides to cancel them out. We'll be left with [tex]\text{m}\angle 2 = \text{m}\angle 3[/tex], which concludes with [tex]\angle 2 \cong \angle 3[/tex] to show the two angles are congruent.

According to the Pythagoras theorem, the value of ED is 8.4 cm

Pythagoras theorem:

Pythagoras theorem defines that the right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Given,

A, B, C, D, E, F, G and H form a cuboid.

AB = 6.7cm, BC = 2.3cm, and CG = 8.1cm.

Now, we need to find the value of Ed and round off it into 1 decimal place.

Here we have the cuboid with the edges named as A, B, C, D, E, F, G and H.

Now, we have to use the value of BC and CG to find the value of hypotenuse of BG.

Because, BG and ED are opposite to each other.

Which means both have the same hypotenuse value.

So, according to the Pythagoras theorem,

=> BG² = BC² + CG²

=> BG² = (2.3)² + (8.1)²

=> BG² = 5.29 + 65.61

=> BG² = 70.9

So, the value of BG is 8.42.

Therefore, the value of ED is 8.4 When we round off this into one decimal place.

it is a parallelogram.

that means both pairs of opposite sides are parallel and the sides of each pair are equally long.

the sum of all internal angles is 360°.

the opposing angles are equal.

and therefore neighboring angles are complementary angles (or a linear pair) : together they have 180°.

so,

76 = 4x - 8

84 = 4x

x = 21

-3z + 8 + 76 = 180

-3z + 84 = 180

-3z = 96

z = -32

-3z + 8 = -6y - 10

The standard deviation of the monthly amount charged is 346.41

Step 1: Identify the values of a and b, where [a , b] is the interval over which the continuous uniform distribution is defined.

Since it takes between 300 and 1500 minutes to be seated at the restaurant, we have:

a = 300

b = 1500

Step 2: Calculate the variance using the formula Var(x) = [tex]\frac{(b-a)^{2} }{12}[/tex]

Using the formula for the variance and the values identified in step 1

(a = 300 , b = 1500), we have:

Var(x) = [tex]\frac{(b-a)^{2} }{12}[/tex]

         = [tex]\frac{(1500 - 300)^{2} }{12}[/tex]
