There is no definite formula for calculation of circumcenter of a triangle but a process for calculation of circumcenter has been described here.

What is circumcenter of a triangle?

Circumcenter of a triangle is the point of intersection of the perpendicular bisectors of every sides of the triangle.

Let the coordinate of A, B, C [tex]\Delta[/tex] ABC be ([tex]x_1, y_1[/tex]), [tex](x_2, y_2)[/tex] and [tex](x_3, y_3)[/tex] respectively and let the coordinate of circumcenter of [tex]\Delta ABC[/tex] is (x, y)

We need to find the length of AB, BC and AC

The length will be obtained in terms of x and y

On solving the equations, we will obtain the value of x and y

The value of x and y is the required coordinate of the circumcenter.

A continuación, se resume el centro, el radio y la longitud de cada intervalo:

Caso A: Centro: 5.5, Radio: 2.5, Longitud: 5

Caso B: Centro: - 1.5, Radio: 3.5, Longitud: 7

Caso C: Centro: 6, Radio: 6, Longitud: 12

Caso D: Centro: - 4.5, Radio: 4.5, Longitud: 9

En este problema tenemos cuatro casos de intervalos de números reales sobre una recta numérica. Los números reales representan un conjunto continuo, no discreto, lo cual significa que existe un número infinito de puntos dentro de la distribución lineal.

El centro es igual al punto medio del intervalo, el radio es la distancia entre el punto medio y cualesquiera de los extremos y la longitud es el doble del radio del intervalo.

Centro:

C = 0.5 · (m + M)

Radio

R = C - m

Longitud

L = 2 · R

Donde:

A continuación, determinamos el centro, el radio y la longitud de cada intervalo:

Caso A

C = 0.5 · (3 + 8) = 0.5 · 11 = 5.5

R = 5.5 - 3 = 2.5

L = 2 · 2.5 = 5

Caso B

C = 0.5 · [(- 5) + 2] = 0.5 · (- 3) = - 1.5

R = - 1.5 - (- 5) = - 1.5 + 5 = 3.5

L = 2 · 3.5 = 7

Caso C

C = 0.5 · (0 + 12) = 6

R = 6 - 0 = 6

L = 2 · 6 = 12

Caso D

C = 0.5 · [(- 9) + 0] = - 4.5

R = - 4.5 - (- 9) = 4.5

L = 2 · 4.5 = 9

Answer:

There are 13 small rooms and 9 large rooms reserved.

Step-by-step explanation:

First, we can make a system of equations. We can use s to represent the number of small rooms and l to represent the number of large rooms.

2 guests per small room added to 3 guests per large room equals 53 guests total, so 2s + 3l = 53.

The number of small rooms (s) plus the number of large rooms (l) equals the total number of rooms, so s + l = 22 or s = 22 - l.

We can substitute the first second equation into the first equation.

2 (22 - l) + 3l = 53

44 - 2l + 3l = 53

l = 9

So, the number of large rooms is 9. Then, to find the number of small rooms, we can substitute l into the second equation.

s = 22 - 9

s = 13

So, the number of small rooms is 13.

The 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481

How to calculate confidence interval?

First, calculate sample proportion by divide number people who favored candidate by number of sample. So:
[tex]\pi[/tex] = 450 / 1,000 = 0.45

Then we use the formula for confidence interval

[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n}}[/tex]

In which z is z score that has a p value of [tex]1 - \frac{\alpha }{2}[/tex]

For 95% confidence interval z is the value of Z that has a p value of [tex]1 - \frac{0.05}{2}[/tex] = 0.975, so z = 1.96

After we have [tex]\pi[/tex] value and z value then put it in the formula. So:

= 0.45 ± [tex]1.96\sqrt{\frac{0.45(1-0.45)}{1000} }[/tex]

= 0.45 ± 0.0308

= 0.419, 0.481

Thus, the 95% confidence interval for the true proportion of people who favored candidate a is 0.419, 0.481

No, Is it not possible that creating a Boxplot could show outliers but z-scores show no outlier. This is because Any z-score that is either higher than +3 or lower than -3 is viewed as an issue.

When you declare a data point to be an outlier and reject it, you are indicating that even if you have already observed the point, it is unlikely to happen again.

Z scores make it easier to determine whether a data value is larger or less than the mean and how far from the mean it is. The Z score precisely indicates the number of standard deviations a data point deviates from the mean.

So, Outliers can be highlighted using scatterplots, histograms, and boxplots. Asterisks or other symbols are displayed on the graph in boxplots to plainly show the presence of outliers in a dataset.

The interest rate for one month is 2.42% and the interest amount is $40 approximately.

Given,

The penalty APR rate = 28.99%

Balance amount = $1800

We have to find the interest for one month;

Here,

The APR of 28.99% is the yearly interest. To find the monthly rate:

= Rate / 12 months

= 28.99% / 12

= 2.42%

The amount owed is therefore;

= 1,800 x 2.42%

= $43.56

Angles 1 and 5 constitutes one of the pairs

Step-by-step explanation:

Since triangle P'Q'R' is the result of a transformation of triangle PQR, an algebraic representation which best describes this transformation is: C. (x, y) → (5x/2, 5y/2).

In Mathematics, a transformation can be defined as the movement of a point from its original (initial) position to a final (new) location. This ultimately implies that, when an object is transformed, all of its points would be transformed as well.

From the information provided above, we can logically deduce the following coordinates:

Therefore, the transformation rule is given by:

P (x, y)                      →               P' (x, y)

Point P = (-1, 1)      →  Point P' = ((5/2 × -1), (5/2 × 1)) = Point P' = (-5/2, 5/2).

A 25 bag sample had a mean of 399 grams and the variance is 400.

There is sufficient evidence at the 0.025 level that the bags are underfilled.

Sample size(n) = 25

sample Mean = 399

Sample Variance = 400

Standard Deviation = √Sample Variance

Standard Deviation = √400

Standard Deviation = 20

Population Mean = 400

So , the null and alternative hypothesis are

H0 : μ = 400

Ha : μ < 400

Using the sample t test statistic

t = (Population Mean - Sample Mean)/(Standard Deviation/Sample size)

t = (400 - 399)/(20/25)

Answer:

m∠1 = 88°

m∠2 = 42°

m∠3 = 113°

Step-by-step explanation:

All of the angles in a triangle add up to 180°. This knowledge can be used to find angle 3, which I will rename c to make writing an equation easier.

[tex]180=25+42+c\\180=67+c\\113=c[/tex]

Angle 3 is 113°

Two angles on either side of the intersection of two straight lines are equal, therefore angle 2, or b:

[tex]b=42[/tex]

Angle 2 is 42°

Now that two angles are known in the leftmost triangle, we can solve for the last one: Angle 1, or a:

[tex]180=50+42+a\\180=92+a\\88=a[/tex]

Angle 1 is 88°

The rate of the square increasing when the area is 16 cm² is 64 cm²/s. The result is obtained by using basic derivative rules.

The rate of a square increasing can be counted by the derivative of the area of the square as a function of time.

dA/dt = 2s ds/dt

Where s is side length.

If each side of a square is increasing at a rate of 8 cm/s, what is the rate of the square increasing when the area is 16 cm²?

We have the side of the square as the function of time.

ds/dt = 8 cm/s

When the area is 16 cm², the side length is

A = s²

16 = s²

s = √16

s = 4 cm

The rate of the square increasing is

dA/dt = 2s ds/dt

dA/dt = 2 × 4 × 8

dA/dt = 64 cm²/s

Hence, the rate of the square increasing when the area is 16 cm² is 64 cm²/s.

The values of x in the given equation are x = -9 and x = 3. The solution set is [-9, 3]

From the question, we are to determine the value of x in the given equation.

The given equation is

|x + 3|= 6

Then, we can write that

x + 3 = 6 and -(x + 3) = 6

Solving the first equation

x + 3 = 6

Subtract 3 from both sides of the equation

x + 3 - 3 = 6 - 3

x = 3

Solving the second equation

-(x + 3) = 6

-x - 3 = 6

Add 3 to both sides of the equation

-x - 3 + 3 = 6 + 3

-x = 9

Multiply both sides of the equation by -1

-1 × -x = -1 × 9

x = -9

Answer:

y = 15

z = 150

Step-by-step explanation:

90°, 2x°, and x and supplementary.

Using this knowledge, we can form the equation:

2x° + 90° + x° = 180°

and solve for x.

3x°+ 90° = 180°

3x° = 90°

x° = 30°

x = 30

x and z are same side interior angles. Therefore, they are supplementary.

Using this knowledge, we can form the equation:

x° + z° = 180°

30° + z° = 180°

z° = 150°

z = 150

z° and 2y° are supplementary.

Using this knowledge, we can form the equation:

z° + 2y° = 180°

150° + 2y° = 180°

2y° = 30°

y° = 15°

y = 15
