The triangle ABC is an isosceles triangle because AB = BC = √73

From the question, we have the following parameters that can be used in our computation:

A(0, 0), B(3, 8), and C(6,0).

An isosceles triangle is any triangle that has two of its sides to be equal

So, we start by calculating the lengths of the sides using the distance equation represented as follows

distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Substitute the known values in the above equation, so, we have the following representation

AB = √[(0 - 3)² + (0 - 8)²]

AB = √73

AC = √[(0 - 6)² + (0 - 0)²]

AC = 6

BC = √[(3 - 6)² + (8 - 0)²]

BC = √73

Because AB = BC = √73, then the triangle is an isosceles triangle

Mindy needs to place the painting at 2.125 feet away from each side of the wall.

The horizontal distance of two side of a wall is defined as width and the vertical distance is called length of wall.

We need to place the paint at an equal distance from each side of wall (horizontal distance).

suppose Mindy will place the paint at x feet away from each side of wall.

for both side she counts 2x feet

width of wall =12.25 feet

width of painting= 8 feet

now, 8+ 2x = 12.25

   2x= 4.25

  x=2.125 feet

hence, Mindy will place the paint at 2.125 feet away from each side horizontally.

It takes 5 years for the population to decrease to 46785 from the current population of 48500 of a small city whose population is decreasing by an average of 325 people per year.

It is given that,

Current population = 48500 people

Rate of decrease = 325 per year

Number of years = x

decreased population after x years  = 46785

Then, the equation is

46785 = 48500 - 325x

On simplifying the obtained equation, we get

46785 = 48500 - 325x

⇒ 325x = 48500 - 46785 = 1625

⇒ x = 1625/325 = 5 years

So, the people become 46785 after 5 years.

In order for mn to be even, m must be even or n must be an even number.

The relationship between two propositions when the subject and predicate of one are respectively the negation of the predicate and the negation of the subject of the other.

Suppose that the statement “m is even or n is even” is not true. Then both m and n are supposed to be odd. Let’s see if the product of two odd numbers is an even or an odd number:

Let n and m be equal to 2a +1  and 2b + 1 respectively, then their product is:

                 (2a +1) (2b + 1) = 4ab + 2a + 2b + 1

                                       = 2(2ab +a + b) + 1

This shows that the expression 2(2ab +a + b) + 1  is of the form 2n +1,  thus the product is odd. If the product of odd numbers is odd, then mn is not true to be even. Therefore, in order for mn to be even, m must be even or n must be an even number.

Step-by-step explanation:

similar objects have the same angles (and as second attribute of the relation there is one common scale factor between the sides of one object to the other).

the naming gives us the first clue about the correct orientation of both objects when establishing the similarity relation :

VWXYZ and

EDCGF

the letters on to of each other corresponds to each other.

formally is actually not really a requirement.

and for that reason we also get Y = 135° and G = 135°.

in combination with the longer and shorter side sequences we know that Y corresponds to G.

and that makes Z correspond with F, and so

Z = F = 117°.

The quadratic model using regression for the given time(seconds) and height (feet) is given by y = 1.287x + 3.602.

Ball will be at 3.28feet when time is equal to 0.43seconds

As given in the question,

From the given time (seconds) and height(feet):

let x be the time and y be the height,

from the table consider two points get the equation of line:

( 0.01, 1.88) and (0.11 , 3.05)

(y - 1.88)/ (x - 0.01) = (3.05 - 1.88)/ (0.11- 0.01)

⇒ y= 11.7x -1.763

Using regression model calculator,

Quadratic model of the data is given by:

y = 1.287x + 3.602

When y = 3.28feet

Then 3.28 = 11.7x - 1.763

⇒x = 0.43seconds

Therefore, the quadratic model of the data using regression is given by y = 1.287x + 3.602 and ball will be at height 3.28feet when time is 0.43seconds.

The wingspan of the model airplane is 16cm having a scale factor of 1:75.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

Given, the original airplane wingspan is 12 meter.

The scale factor given is 1:75

Let us consider the wingspan of the model plane to be 'l'

Thus, model wingspan/original wingspan = 1/75

⇒ l/12 = 1/75

⇒ l = 12/75

(b) The mean number of components out of 3 that fail, E[X] is 0.45.

(c) The var(X) is 0.3825.

(d) The probability that the entire system is successful, is 0.9966.

(e) The probability that the system fails is 0.0034.

(a) In the given question we have to write out a probability function for the random variable X.

Let X denote number of component out of 3 that fail. SO the random variable X can take 0, 1, 2 and 3.

Here the components act independently and that they equivalent in the sense that all 3 of them have an 85% success rate.

So the failure rate, 1-0.85 = 0.15

Thus X follows binomial distribution with parameters n=3 and p=0.15.

The probability function for the random variable X is

P(X = x) = [tex]^{3}C_{x}(0.15)^x(0.85)^{3-x}[/tex] at X=0,1,2 and 3 otherwise it is 0.

(b) Now we have to find E[X], the mean number of components out of 3 that fail.

E[X] = np

E[X] = 3*0.15

E[X] = 0.45

(c) Now we have to find the var(X).

var(X) = np(1-p)

var(X) = 3*0.15p(1-0.15)

var(X) = 0.3825

(d) Now we have to find the probability that the entire system is successful.

P(at least one component will work) = 1-P(All the component fail)

P(at least one component will work) = 1-P(X = 3)

P(at least one component will work) = 1-[tex]^3C_{3}(0.15)^3(0.85)^{3-3}[/tex]

P(at least one component will work) = 1-0.0034

P(at least one component will work) = 0.9966

(e) Now we have to find the probability that the system fails.

P(All the component fail) = P(X = 3)

P(All the component fail) = [tex]^3C_{3}(0.15)^3(0.85)^{3-3}[/tex]

The measurement of all the angles in the given geometrical image are mentioned below.

Given is a figure as shown in the image.

We can write the following equations -

∠1 + ∠2 + (8x - 8)° + (3x + 17)° = 360°

and

(8x - 8)° = (3x + 17)°                               {Vertically opposite angles}

8x - 3x = 17 + 8

5x = 25

x = 5

So -

8x - 8 = 8 x 5 - 8 = 32°

3x + 17 = 3 x 5 + 17 = 32°

So -

∠1 + ∠2 + (2 x 32) = 360°

2∠1 + 64 = 360

2∠1 = 296

∠1 = 148° = ∠2                                   {Vertically opposite angles}

∠6 = ∠1 = 148°

∠3 = 32°

∠5 = (180 - 148) = 32°

∠4 = 148°

∠6 = 148°

∠5 = 32°

Now -

(4y + 44) + (6y + 46) = 180°

10y + 90 = 180

10y = 90

y = 9

So -

(4y + 44) = 4 x 9 + 44 = 36 + 44 = 80

∠8 = 80°

Now -

6y + 46 = 6 x 9 + 46 = 100°

∠10 = 100°

∠11 = 80°

∠7 = ∠10 = 100°

∠7 = 100°

∠11 = ∠12 = 80°

∠12 = 80°

The millimetres of each solution needed are 80 millimetres and 50 millimetres, respectively

From the question, we have the following parameters that can be used in our computation:

Volume needed  = 130mL

Proportion = 59%

Available proportions = 44% and 83%

Represent the type of solutions with x and y

So, we have the following system of equations:

x  + y = 130

0.44x + 0.83y = 59% * 130

So, we have

x  + y = 130

0.44x + 0.83y = 76.7

Make x the subject in x  + y = 130

x = 130 - y

Substitute x = 130 - y in 0.44x + 0.83y = 76.7

0.44(130 - y) + 0.83y = 76.7

So, we have

57.2 - 0.44y + 0.83y = 76.7

Evaluate the like terms

0.39y = 19.5

Divide both sides by 0.39

y = 50

Substitute y = 50 in x = 130 - y

x = 130 - 50

The correlation coefficient of -0.98 suggests a negative association between the two predictor variables.

Correlation coefficients measure the strength of a linear relationship between two variables, x and y. A value less than zero denotes a negative relationship.

The correlation coefficient can have values ranging from -1.0 to 1.0. In other words, the numbers must be larger than or less than 1.0. A correlation of -1.0 indicates that there is a perfect negative connection, whereas a correlation of 1.0 indicates that there is a perfect positive correlation.

A positive link is represented by a correlation coefficient greater than zero. The connection is negative if the value is less than zero. A value of 0 indicates that there is no association between the two variables.

Before analysing the correlation, the covariance of the two variables in question must be evaluated. Electronic commerce refers to the sale of electronic items. The correlation coefficient is computed by dividing the covariance by the product of the two variables' standard deviations.
