Find the circumcenter of the triangle.

Answer:

25 median. 29 mean.

Step-by-step explanation:

7, 16, 18, 25, 43, 47, 47

25 is the middle number when ordered by value, so 25 is the median

7 + 47 + 43 + 47 + 25 + 16 + 18 = 203

203 / 7 (amount of numbers in the set) = 29

The cost of labor per hour is $125.

The equation that can be used to solve for the cost of labor per hour is a linear equation. A linear equation is an equation that has a single variable that is raised to the power of one.

The form of the linear equation is:

Total cost = cost of the parts + (cost per hour x total hours worked)

$585.25 = $54 + (4.25 x d)

$585.25 = $54 + 4.25d

In order to determine the value of x, take the following steps:

Combine similar terms:

$585.25 - $54 = 4.25d

Add similar terms

$531.25 = 4.25d

Divide both sides of the equation by 4.24

d = 531.25 / 4.25

d = 125

Answer: The formula for the mathematical function that takes as input an RGB color vector ⟨r,g,b⟩ and yields as output the RGB color vector that is the unique shade of gray whose total amount of light (r+g+b) is equal to that of the input is:

(r+g+b)/3, (r+g+b)/3, (r+g+b)/3

Step-by-step explanation: RGB color space is a way to represent colors digitally, where each color is represented by a combination of red, green, and blue values ranging from 0 to 255. To obtain a unique shade of gray whose total amount of light (r+g+b) is equal to that of the input color, we have to set all three color channels to the average value of the red, green and blue values.

To calculate this average value we use the formula: (r+g+b)/3

So the output of the function is ⟨(r+g+b)/3, (r+g+b)/3, (r+g+b)/3⟩ which is the unique shade of gray whose total amount of light is equal to that of the input color.

Note: This is one way to convert color to gray, other methods exist like using luminosity or other weights to RGB channels.

If Just before Henderson Laboratories opened for business. The totals that would appear in the firm’s fundamental accounting equation is $96,875

Using this formula

Assets = Liabilities + Owner’s Equity

Total Owners Equity = Assets - Liabilities

Where:

Assets:

Assets = Laboratory Equipment + Laboratory supplies+ Cash

Assets=$75,000 + $6,200 + $39,900

Asset= $121,100

Liabilities:

Liabilities= Loan Payable+ Accounts Payable

Liabilities = $14,500 + $9,725

Liabilities= $24,225

Let plug in the formula

Total Owners Equity = Assets - Liabilities

Total Owners Equity =$121,100 - $24,225

The total height of the building would be nh + 30.

Option (B) is correct.

What is a simplification in mathematics?

In mathematics, simplification refers to the process of making an expression or equation simpler or easier to understand or work with. This can involve combining like terms, removing unnecessary terms or factors, or rearranging the order of the terms.

The building's total height in feet is represented by the sum of the height of each floor plus the height of the spire.

So if the height of each floor is h, and there are n floors in the building and the building's spire is 30 feet, the total height of the building is:

= n * h + 30

=nh + 30

This is because the height of each floor is h, and there are n floors, so the total height of the floors is n * h. Adding the height of the spire, 30 feet, to the total height of the floors gives nh + 30.

Hence, the total height of the building would be nh + 30.

What is a perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. The perimeter of a shape is obtained by adding up the length of all the sides and edges of the shape. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

Now, let's assume a geometric system of a square and a parallelogram having the same base and equivalent side of the square " a ".

Therefore, the respective two parallel sides of the Parallelogram will also be equal to " a ".

Now, let's rotate the one of the parallel lines with angle Φ clockwise then, the side lengths which aren't equal and parallel to the first set will get increased and it's incremental rate will be responsible for the increase in perimeter of the figures aslike , perimeter is the sum of the sides of the figure.

Now let's rotate alternate side length at maximum at angle θ , aslike it should touch the square at diagonally opposite angles ,

Now, let's calculate perimeters of both the figures -

Square of side length " a " = a + a + a + a = 4a

Parallelogram of two base side length " a " and two parallel set lines of length √2a

= a + a + √2a + √2a

Answer:

Step-by-step explanation:

The problem can be solved by using the information provided to set up a system of equations and then solving for the unknown variable, which in this case is the fixed charge.

Let x be the fixed charge.

We know that the total cost of the 11-mile trip is the fixed charge plus the charge for the distance covered, so we can write the equation:

x + 11y = 88 (1)

We also know that the total cost of the 16-mile trip is the fixed charge plus the charge for the distance covered, so we can write the equation:

x + 16y = 108 (2)

Where y is the cost per mile

We can solve for y by subtracting equation (1) from equation (2), so:

16y - 11y = 108 - 88

5y = 20

y = 4

Now we know that cost per mile is 4$, we can substitute it in equation (1)

x + 11(4) = 88

x = 24

Now we know the fixed charge is 24$ and cost per mile is 4$, we can calculate the fare for 6 miles

24 + 6(4) = $48

Therefore, Linus would have to pay $48 to travel 6 miles.

Answer: The probability that a waitress will refuse to serve alcoholic beverages to only three minors if she randomly checks the IDs of five students from among ten students of which four are not of legal age is 0.288 or 28.8%.

Step-by-step explanation:

he probability of a waitress refusing to serve alcoholic beverages to only three minors if she randomly checks the IDs of five students can be calculated using the binomial probability formula.

The binomial probability formula is: P(x) = (n choose x) * p^x * (1-p)^(n-x)

Where:

x = the number of successful outcomes (in this case, the number of minors refused service)

n = the total number of trials (in this case, the number of IDs checked)

p = the probability of a successful outcome in a single trial (in this case, the probability that a randomly chosen student is a minor)

In this case:

x = 3 (the number of minors refused service)

n = 5 (the number of IDs checked)

p = 4/10 (the probability that a randomly chosen student is a minor)

So, the probability of a waitress refusing to serve alcoholic beverages to only three minors if she randomly checks the IDs of five students can be calculated as:

P(3) = (5 choose 3) * (4/10)^3 * (6/10)^2 = (10/3) * (0.16) * (0.36) = 0.288

Therefore, the probability of a waitress refusing to serve alcoholic beverages to only three minors if she randomly checks the IDs of five students is 0.288 or 28.8%.

It's worth noting that this problem assumes that the waitress randomly chooses the 5 students, if the waitress doesn't pick them randomly the result may be different.

Answer:

Step-by-step explanation:

An identity is an equality that is always true. An equation is an equality that is (only necessarily) conditionally true.

That is to say that for any real value inputted into a variable in an identity, an equality will result, whereas only certain values for a variable in an equation will necessarily result in an equality.

If the given equation is an identity, it should result in an equality no matter what the input for k is. So, to prove that it isn't an identity, we simply have to find one value for k that results in an inequality. To do so, we can simply plug in 0 for k and simplify.

[tex]k - 4 = 4 + k[/tex]

[tex]0 - 4 \stackrel{?}{=} 4 + 0[/tex]

[tex]-4 \ne 4[/tex]

We have found one value for k that results in an inequality. Thus, this equation is not an identity.

The regression equation, given the line of best fit and the points on the line, would be F ( x ) = 30x + 685

To find the regression equation, you first need to find two points on the line on the graph. Those two lines would be ( 3, 775) and ( 4 , 805).

The next step would be to find the slope of the line :

= ( Y₂ - Y ₁ ) / ( X ₂ - X  ₁ )

= ( 805 - 775 ) / ( 4 - 3 )

= 30 / 1

= 30

Then use the points to find the y - intercept :

y =  mx + y- intercept

775 = 30 ( 3 ) + y - intercept

y - intercept = 775 - 90
