Answer:

The probability of getting one ten from the deck of 52 cards is 4/52, since there are four tens in the deck. After one ten is drawn, there are only 51 cards remaining in the deck.

Step-by-step explanation:

The probability of getting four kings from the remaining 51 cards is (4/51) * (3/50) * (2/49) * (1/48), since there are four kings left in the deck after the ten is drawn, and the probability of drawing a king decreases with each card drawn.

Therefore, the probability of getting one ten and four kings is:

(4/52) * (4/51) * (3/50) * (2/49) * (1/48)

= 0.0000026

This is an extremely low probability, since the chances of getting this specific combination of cards is very low.

The function for the value of the account after t years is: [tex]V(t) = 5900 * (1 + 0.056/365)^{(365*t)[/tex]and the percentage of growth per year is 5.74%.

A percentage is a way of expressing a quantity as a fraction of 100. It is often used to compare two quantities or to express a part of a whole.

In mathematics, a function is a rule that assigns to each element in one set (called the domain) exactly one element in another set (called the range).

The formula for calculating the value of the account after t years is:

[tex]V(t) = 5900 * (1 + 0.056/365)^{(365*t)[/tex]

where 0.056 is the annual interest rate (APR), divided by 100 to convert it to a decimal, and 365 is the number of days in a year.

To find the annual percentage yield (APY), we can use the formula:

[tex]APY = (1 + APR/n)^{n - 1[/tex]

where n is the number of times the interest is compounded per year. In this case, the interest is compounded daily, so n = 365.

[tex]APY = (1 + 0.056/365)^{365 - 1} = 0.0574\ or\ 5.74%[/tex]

Therefore, the function for the value of the account after t years is:

[tex]V(t) = 5900 * (1 + 0.056/365)^{(365*t)[/tex]

Answer:

Centre = (3, 5)

Radius = [tex]\sqrt{131}[/tex]

Step-by-step explanation:

Given equation of a circle:

[tex]-6x + x^2 = 97 + 10y - y^2[/tex]

To find the centre and radius of the given equation of a circle, rewrite it in standard form.

[tex]\boxed{\begin{minipage}{6.3cm}\underline{Equation of a Circle - Standard Form}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the centre. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

First, rearrange the equation so that the terms in x and y are on the left side and the constant is on the right side:

[tex]x^2 - 6x + y^2 - 10y = 97[/tex]

Complete the square for the x and y terms by adding the square of half the coefficient of the term in x and y to both sides:

[tex]\implies x^2 - 6x +\left(\dfrac{-6}{2}\right)^2+ y^2 - 10y +\left(\dfrac{-10}{2}\right)^2= 97+\left(\dfrac{-6}{2}\right)^2+\left(\dfrac{-10}{2}\right)^2[/tex]

Simplify:

[tex]\implies x^2 - 6x +\left(-3\right)^2+ y^2 - 10y +\left(-5\right)^2= 97+\left(-3\right)^2+\left(-5\right)^2[/tex]

[tex]\implies x^2 - 6x +9+ y^2 - 10y +25= 97+9+25[/tex]

[tex]\implies x^2 - 6x +9+ y^2 - 10y +25= 131[/tex]

Now we have created two perfect square trinomials on the left side of the equation:

[tex]\implies (x^2 - 6x +9)+ (y^2 - 10y +25)= 131[/tex]

Factor the perfect square trinomials:

[tex]\implies (x-3)^2+ (y-5)^2= 131[/tex]

If we compare this equation with the standard form, we see that the centre of the circle is (3, 5) and its radius is the square root of 131.

Therefore:

The area of one of the bases of the pentagonal prism is approximately 172.96 square units.

What is Area ?

Area is a measure of the amount of space inside a two-dimensional shape, such as a square, rectangle, triangle, circle, or any other shape that has a length and a width. It is usually measured in square units, such as square inches, square feet, or square meters.

To find the area of one of the bases of the pentagonal prism, we need to use the formula for the volume of a pentagonal prism, which is:

V = (1÷2)Ph,

where V is the volume, P is the perimeter of the base, h is the height of the prism.

Since we know that the height of the prism is 13.4 units and the volume is 321.6 , we can solve for the perimeter of the base:

V = (1÷2)Ph

321.6 = (1÷2)P(13.4)

P = 48

The perimeter of the base is 48 units.

To find the area of one of the bases, we can use the formula for the area of a regular pentagon, which is:

A = (5÷4) [tex]s^{2}[/tex]* tan(π÷5)

where A is the area of the pentagon and s is the length of a side.

Since the pentagon is regular, all sides have the same length. Let's call this length "x".

The perimeter of the pentagon is 48 units, so we have:

5x = 48

x = 9.6

Now we can use the formula for the area of a regular pentagon to find the area of one of the bases:

A = (5÷4)[tex]x^{2}[/tex] * tan(π÷5)

A = (5÷4)(9.6*9.6) * tan(π÷5)

A ≈ 172.96

Therefore, the area of one of the bases of the pentagonal prism is approximately 172.96 square units.

Answer:

The given expression is divisible by both 30 and 37

Step-by-step explanation:

First, let's consider the expression (36^5-6^9). We can factor out 6^5 from both terms to get:

(36^5-6^9) = 6^5(6^10-36^3)

Next, let's consider the expression (38^9-38^8). We can factor out 38^8 from both terms to get:

(38^9-38^8) = 38^8(38-1)

Now, we can substitute these factorizations back into the original expression:

(36^5-6^9)(38^9-38^8) = 6^5(6^10-36^3)38^8(38-1)

To show that this expression is divisible by 30, we need to show that it is divisible by both 2 and 3. We can see that 6^5 is divisible by both 2 and 3, so the entire expression is divisible by 2 and 3, and hence divisible by 30.

To show that this expression is divisible by 37, we can use Fermat's Little Theorem, which states that if p is a prime number and a is any integer not divisible by p, then a^(p-1) is congruent to 1 mod p. In this case, p=37 and a=6, so we can write:

6^36 ≡ 1 (mod 37)

Multiplying both sides by 6^10 gives:

6^46 ≡ 6^10 (mod 37)

We can use this congruence to simplify the expression we are interested in:

(36^5-6^9)(38^9-38^8) ≡ (6^10-6^9)(1-38^-1) (mod 37)

Simplifying this expression further gives:

(6^10-6^9)(1-38^-1) ≡ 0 (mod 37)

Therefore, the expression (36^5-6^9)(38^9-38^8) is divisible by both 30 and 37.

We have shown that the sum of the elements in G is equal to zero, as required.

An abelian group, also known as a commutative group in mathematics, is a set of elements where the outcome of applying the group operation on two elements of the set does not depend on the order in which the elements are written. The group operation is hence commutative. The integers and real numbers both form abelian groups when addition is used as an operation, and the idea of an abelian group can be seen as a generalisation of these cases.

We can prove this statement using the fact that the sum of the elements in an abelian group is always equal to zero.

Since G is a finite abelian group, every element ai in G has an inverse, denoted by -ai. Furthermore, since G is abelian, the order in which we add the elements does not matter. Therefore, we can rearrange the terms in the sum a1 + a2 + ... + an so that all of the terms are paired with their inverse:

a1 + a2 + ... + an = (a1 + (-a1)) + (a2 + (-a2)) + ... + (an + (-an))

Since n is odd, we have an odd number of elements in G, which means that we have an odd number of pairs of the form ai + (-ai). Therefore, there is exactly one element in the sum that is not paired with its inverse, which is either ai or -ai for some i.

Without loss of generality, suppose that ai is the element that is not paired with its inverse. Then, we have:

a1 + a2 + ... + ai + ... + an = (a1 + (-a1)) + (a2 + (-a2)) + ... + (ai + (-ai)) + ... + (an + (-an))

= 0 + 0 + ... + 0 + ai + (-ai) + ... + 0

= ai - ai

= 0

Therefore, we have shown that the sum of the elements in G is equal to zero, as required.

What is area of the square?

Side × Side

Given, the area of the painting, which is 360 square inches, and we know that the side of the square is (3x + 2) inches. So we can set up an equation,

(3x + 2)² = 360

Expanding the left side,

9x²+ 12x + 4 = 360

Subtracting 360 from both sides,

9x² + 12x - 356 = 0

Now we can use the quadratic formula to solve for x,

[tex]x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]

In this case, a = 9, b = 12, and c = -356. Plugging these values into the formula, we get:

[tex]x = \frac{ - 12 \pm \sqrt{ {12}^{2} - 4 \times 9} }{2 \times 9} \\ = \frac{ - 12 \pm \sqrt{144 - 36} }{18} [/tex]

By solving,we will get [tex]x = - \frac{7}{3} \: or \: \frac{20}{3} [/tex]

The range would grow by 12 if the data included a second person who is 46 years old.

The difference between the data set's maximum and smallest values is known as the range.

In the given data set, the minimum value is 15 and the maximum value is 34. So, the range is:

Range = maximum value - minimum value

Range = 34 - 15

Range = 19

If we add another age of 46 to the data set, then the new maximum value would be 46 and the new range would be:

New range = new maximum value - minimum value

New range = 46 - 15

Answer:

the circumcenter of triangle ABC is the point (3, 7/3).

Step-by-step explanation:

To find the circumcenter of triangle ABC, we need to find the intersection point of the perpendicular bisectors of its sides.

First, let's find the midpoint and slope of each side of the triangle:

Side AB: midpoint = (0,1), slope = undefined (vertical line)

Side AC: midpoint = (3,2), slope = -1/3

Side BC: midpoint = (3,-1/2), slope = 3/2

Next, we need to find the equations of the perpendicular bisectors of each side. The perpendicular bisector of a segment is the line that passes through its midpoint and is perpendicular to the segment.

Perpendicular bisector of AB: x = 0 (it is a vertical line passing through the midpoint of AB)

Perpendicular bisector of AC: passes through the midpoint (3,2) and has a slope of the negative reciprocal of AC's slope, which is 3

Therefore, the equation of the perpendicular bisector of AC is y - 2 = -1/3 (x - 3), which simplifies to y = -x/3 + 8/3

Perpendicular bisector of BC: passes through the midpoint (3,-1/2) and has a slope of the negative reciprocal of BC's slope, which is -2/3

Therefore, the equation of the perpendicular bisector of BC is y + 1/2 = -2/3 (x - 3), which simplifies to y = -2x/3 + 7/2

Now we need to find the intersection point of any two of these perpendicular bisectors. We can choose any two, but it is usually easier to choose the ones that have equations in slope-intercept form, which are the perpendicular bisectors of AC and BC.

Solving the system of equations y = -x/3 + 8/3 and y = -2x/3 + 7/2, we get x = 3 and y = 7/3.

Therefore, the circumcenter of triangle ABC is the point (3, 7/3).
