The standard deviation of the weights for the 10 adults is approximately 3.36 kg.

To determine the standard deviation of the weights for the 10 adults, you can follow these steps:

Calculate the mean of the weights:

Mean = (72 + 78 + 76 + 86 + 77 + 77 + 80 + 77 + 82 + 80) / 10 = 787 / 10 = 78.7 kg

Calculate the deviation of each weight from the mean:

Deviation = Weight - Mean

For example, the deviation for the first weight (72 kg) is 72 - 78.7 = -6.7 kg.

Square each deviation:

Square of Deviation = Deviation^2

For example, the square of the deviation for the first weight is (-6.7)^2 = 44.89 kg^2.

Calculate the variance:

Variance = (Sum of the squares of deviations) / (Number of data points)

Variance = (44.89 + 2.89 + 1.69 + 49.69 + 0.09 + 0.09 + 1.69 + 0.09 + 9.69 + 1.69) / 10

= 113.1 / 10

= 11.31 kg^2

Take the square root of the variance to get the standard deviation:

Standard Deviation = √(Variance) = √(11.31) ≈ 3.36 kg

Answer:length 16 cm breath 6 cm

Step-by-step explanation:

Let's assume the breadth of the rectangle is "x" cm.

According to the given information, the length of the rectangle exceeds twice its breadth by 4 cm. So, the length can be expressed as 2x + 4 cm.

The perimeter of a rectangle is given by the formula: Perimeter = 2(length + breadth).

Substituting the values we have, the perimeter of the rectangle is:

44 cm = 2((2x + 4) + x)

Now, we can solve this equation to find the value of x:

44 cm = 2(3x + 4)

44 cm = 6x + 8

6x = 44 - 8

6x = 36

x = 36/6

x = 6

So, the breadth of the rectangle is 6 cm.

To find the length, we substitute the value of x back into the expression for length:

Length = 2x + 4

Length = 2(6) + 4

Length = 12 + 4

Length = 16 cm

Therefore, the length of the rectangle is 16 cm and the breadth is 6 cm.

Alright, let's take this step by step.

First, let's understand what an ordinary annuity is. An ordinary annuity is a series of equal payments made at the end of consecutive periods over a fixed length of time. For example, if you save $100 every year for 5 years, that’s an ordinary annuity.

Now, let’s understand the formula to calculate the future value (FV) of an ordinary annuity:

FV = P x ((1 + r)^n - 1) / r

Where:

- FV is the future value of the annuity.

- P is the payment per period (how much you save each time).

- r is the interest rate per period (in decimal form).

- n is the number of periods (how many times you save).

Let’s solve each part:

a) $500 per year for 6 years at 8%.

P = 500, r = 8% = 0.08, n = 6

FV = 500 x ((1 + 0.08)^6 - 1) / 0.08

  ≈ 500 x (1.59385 - 1) / 0.08

  ≈ 500 x (0.59385) / 0.08

  ≈ 500 x 7.4231

  ≈ 3701.55

So, the future value of $500 per year for 6 years at 8% is about $3,701.55.

b) $250 per year for 3 years at 4%.

P = 250, r = 4% = 0.04, n = 3

FV = 250 x ((1 + 0.04)^3 - 1) / 0.04

  ≈ 250 x (1.12486 - 1) / 0.04

  ≈ 250 x (0.12486) / 0.04

  ≈ 250 x 3.1215

  ≈ 780.38

So, the future value of $250 per year for 3 years at 4% is about $780.38.

c) $1,000 per year for 2 years at 0%.

P = 1000, r = 0% = 0.00, n = 2

FV = 1000 x ((1 + 0.00)^2 - 1) / 0.00

  = 1000 x (1 - 1) / 0.00

  = 1000 x 0

  = 0

Wait, something went wrong, because we know that if we save $1000 for 2 years with no interest, we should have $2000. This is a special case, where we just sum the contributions because there's no interest:

FV = 1000 x 2

   = 2000

So, the future value of $1,000 per year for 2 years at 0% is $2,000.

An annuity due is similar to an ordinary annuity, but the payments are made at the beginning of each period instead of the end. To convert the future value of an ordinary annuity to an annuity due, you can use the following formula:

FV of Annuity Due = FV of Ordinary Annuity x (1 + r)

a) Reworked

FV of Annuity Due = 3701.55 x (1 + 0.08)

                 ≈ 3701

.55 x 1.08

                 ≈ 3997.67

b) Reworked

FV of Annuity Due = 780.38 x (1 + 0.04)

                 ≈ 780.38 x 1.04

                 ≈ 810.80

c) Reworked

FV of Annuity Due = 2000 x (1 + 0.00)

                 = 2000 x 1

                 = 2000 (This doesn't change because there's no interest).

And there you have it! The future values for both ordinary annuities and annuities due!

The diameter of the circle is approximately 8.50 yards and the radius is approximately 4.25 yards.

To find the diameter and radius of a circle when given the circumference, we can use the formulas:
Circumference = 2πr
Diameter = 2r
Given that the circumference is C = 26.7 yd, we can substitute this value into the circumference formula:
26.7 = 2πr
To find the radius, we need to isolate it on one side of the equation. Dividing both sides of the equation by 2π, we get:
r = 26.7 / (2π)
Now we can calculate the value of r using a calculator:
r ≈ 4.25 yd (rounded to the nearest hundredth)
To find the diameter, we can multiply the radius by 2:
Diameter = 2 * 4.25 ≈ 8.50 yd (rounded to the nearest hundredth)

The new ratio of the siblings' share of sweets is 19:28:25. Thus, option A is correct..

Initially, the siblings shared the 42 chocolate sweets according to the ratio 3:6:5.

To find the total number of parts in the ratio, we add the individual ratios: 3 + 6 + 5 = 14 parts.

To determine the share of each sibling, we divide the total number of sweets (42) into 14 parts:

Trust's share = (3/14) * 42 = 9 sweets

Hardlife's share = (6/14) * 42 = 18 sweets

Innocent's share = (5/14) * 42 = 15 sweets

Now, their father buys an additional 30 chocolate sweets and gives 10 to each sibling. This means that each sibling's share increases by 10.

Trust's new share = 9 + 10 = 19 sweets

Hardlife's new share = 18 + 10 = 28 sweets

Innocent's new share = 15 + 10 = 25 sweets

The minimal possible value of ||Ax - b|| is 0.

To find the minimal possible value of ||Ax - b|| for x ∈ R², we need to minimize the distance between the vector Ax and b.

Given A = 5 and b = 3, the expression ||Ax - b|| represents the Euclidean norm (also known as the 2-norm or the length) of the vector Ax - b.

We can calculate this value as follows:

Ax = [5x₁, 5x₂] (where x = [x₁, x₂])

Ax - b = [5x₁, 5x₂] - [3, 3] = [5x₁ - 3, 5x₂ - 3]

||Ax - b|| = sqrt((5x₁ - 3)² + (5x₂ - 3)²)

To find the minimal possible value of ||Ax - b||, we need to find the values of x₁ and x₂ that minimize the expression inside the square root.

Since we want to minimize the square root expression, we can minimize its square instead:

f(x₁, x₂) = (5x₁ - 3)² + (5x₂ - 3)²

To find the minimum, we can take partial derivatives concerning x₁ and x₂ and set them equal to zero:

∂f/∂x₁ = 10(5x₁ - 3) = 0

∂f/∂x₂ = 10(5x₂ - 3) = 0

Solving these equations gives:

5x₁ - 3 = 0 --> 5x₁ = 3 --> x₁ = 3/5

5x₂ - 3 = 0 --> 5x₂ = 3 --> x₂ = 3/5

Therefore, the values of x₁ and x₂ that minimize the expression ||Ax - b|| are x₁ = 3/5 and x₂ = 3/5.

Substituting these values back into the expression, we get:

||Ax - b|| = sqrt((5(3/5) - 3)² + (5(3/5) - 3)²)

= sqrt((3 - 3)² + (3 - 3)²)

= sqrt(0 + 0)

= 0

Hence, the minimal possible value of ||Ax - b|| is 0.

Answer:

P(rolling a 3) = 1/6

The 1 goes in the green box.

If a and b are congruent modulo m, they will also be congruent modulo cm, implying that their difference is divisible by both m and cm.

When two numbers, a and b, are congruent modulo m (denoted as a ≡ b (mod m)), it means that the difference between a and b is divisible by m. In other words, (a - b) is a multiple of m.

To prove that if a ≡ b (mod m), then a ≡ b (mod cm), we need to show that the difference between a and b is also divisible by cm.

Since a ≡ b (mod m), we can express this congruence as (a - b) = km, where k is an integer. Now, we need to prove that (a - b) is also divisible by cm.

To do this, we can rewrite (a - b) as (a - b) = (km)(c). Since k and c are both integers, their product (km)(c) is also an integer. Therefore, (a - b) is divisible by cm, which can be expressed as a ≡ b (mod cm).

In simpler terms, if the difference between a and b is divisible by m, it will also be divisible by cm because m is a factor of cm. This demonstrates that if a ≡ b (mod m), then a ≡ b (mod cm).

The given function is y = 3cos(-θ/3). The period of the given function is 6π, its range is [-3,3] and the amplitude of 3.

The period of a cosine function is determined by the coefficient of θ. In this case, the coefficient is -1/3. The period, denoted as T, can be found by taking the absolute value of the coefficient and calculating the reciprocal: T = |2π/(-1/3)| = 6π. Therefore, the period of the function is 6π.

The range of a cosine function is the set of all possible y-values it can take. Since the coefficient of the cosine function is 3, the amplitude of the function is |3| = 3. The range of the function y = 3cos(-θ/3) is [-3, 3], meaning the function's values will oscillate between -3 and 3.

- The period of a cosine function is the length of one complete cycle or oscillation. In this case, the function has a period of 6π, indicating that it will complete one full oscillation over an interval of 6π units.

- The range of the function y = 3cos(-θ/3) is [-3, 3] because the amplitude is 3. The amplitude determines the vertical stretch or compression of the function. It represents the maximum displacement from the average value, which in this case is 0. Therefore, the graph of the function will oscillate between -3 and 3 on the y-axis.

In summary, the given function y = 3cos(-θ/3) has a period of 6π, a range of [-3, 3], and an amplitude of 3.

The function has a relative minimum at (2, 2, 0) and a saddle point at (0, 0, 8).

The function f(x, y) = x³ - 6xy + y³ + 8 is given, and we need to determine the relative extrema and saddle points of this function.

To find the relative extrema and saddle points, we need to calculate the partial derivatives of the function with respect to x and y. Let's denote the partial derivative with respect to x as f_x and the partial derivative with respect to y as f_y.

1. Calculate f_x:
To find f_x, we differentiate f(x, y) with respect to x while treating y as a constant.

f_x = d/dx(x³ - 6xy + y³ + 8)
    = 3x² - 6y

2. Calculate f_y:
To find f_y, we differentiate f(x, y) with respect to y while treating x as a constant.

f_y = d/dy(x³ - 6xy + y³ + 8)
    = -6x + 3y²

3. Set f_x and f_y equal to zero to find critical points:
To find the critical points, we need to set both f_x and f_y equal to zero and solve for x and y.

Setting f_x = 3x² - 6y = 0, we get 3x² = 6y, which gives us x² = 2y.

Setting f_y = -6x + 3y² = 0, we get -6x = -3y², which gives us x = (1/2)y².

Solving the system of equations x² = 2y and x = (1/2)y², we find two critical points: (0, 0) and (2, 2).

4. Classify the critical points:
To determine the nature of the critical points, we can use the second partial derivatives test. This involves calculating the second partial derivatives f_xx, f_yy, and f_xy.

f_xx = d²/dx²(3x² - 6y) = 6
f_yy = d²/dy²(-6x + 3y²) = 6y
f_xy = d²/dxdy(3x² - 6y) = 0

At the critical point (0, 0):
f_xx = 6, f_yy = 0, and f_xy = 0.
Since f_xx > 0 and f_xx * f_yy - f_xy² = 0 * 0 - 0² = 0, the second partial derivatives test is inconclusive.

At the critical point (2, 2):
f_xx = 6, f_yy = 12, and f_xy = 0.
Since f_xx > 0 and f_xx * f_yy - f_xy² = 6 * 12 - 0² = 72 > 0, the second partial derivatives test confirms that (2, 2) is a relative minimum.

Therefore, the relative minimum is (2, 2, 0).

To determine if there are any saddle points, we need to examine the behavior of the function around the critical points.

At (0, 0), we have f(0, 0) = 8. This means that (0, 0, 8) is a relative minimum.

At (2, 2), we have f(2, 2) = 0. This means that (2, 2, 0) is a saddle point.

In conclusion, the function f(x, y) = x³ - 6xy + y³ + 8 has a relative minimum at (2, 2, 0) and a saddle point at (0, 0, 8).

The trend in a time series refers to the long-term movement or direction of the data. It represents the underlying pattern or growth rate over an extended period. For example, if we analyze the sales data of a company over several years, we might observe a steady increase in sales, indicating a positive trend. On the other hand, if the data shows a decline over time, it indicates a negative trend.

Seasonality in a time series refers to the repetitive pattern or fluctuations that occur within a fixed time period, typically a year. These patterns are usually influenced by natural or calendar factors such as weather, holidays, or cultural events. For instance, if we analyze the monthly ice cream sales data, we might observe higher sales during the summer months and lower sales during the winter months due to the seasonal demand for ice cream.

Cyclical patterns in a time series represent the fluctuations that occur over a medium-term period, typically spanning several years. These patterns are often related to economic or business cycles. For example, the housing market may experience periods of expansion and contraction due to factors such as interest rates, employment rates, or consumer confidence. These cyclical fluctuations can have an impact on various industries, including real estate and construction.

It's important to note that the distinction between seasonal and cyclical patterns can sometimes be blurred, as both involve repeated patterns. However, the key difference lies in the duration of the pattern. Seasonal patterns occur within a fixed time period, while cyclical patterns occur over a medium-term period.

In summary, the trend represents the long-term movement or direction of the data, while seasonality and cyclical patterns refer to shorter-term repetitive fluctuations. Understanding these components is essential for analyzing and forecasting time series data.

Answer:

m = 7, -8

Step-by-step explanation:

√(56-m) = m

To remove the radical on the left side of the equation, square both sides of the equation.

[tex]\sqrt{(56-m)}[/tex]² = m²

Simplify each side of the equation.

56 - m = m²

Now we solve for m

56 - m = m²

56 - m - m² = 0

We factor

- (m - 7) (m + 8) = 0

m - 7 = 0

m = 7

m + 8 = 0

m = -8

So, the answer is m = 7, -8

Answer:

√(56 - m) = m

Square both sides to clear the radical.

56 - m = m²

Add m to both sides, then subtract 56 from both sides.

m² + m - 56 = 0

Factor this quadratic equation.

(m - 7)(m + 8) = 0

Set each factor equal to zero, and solve for m.

m - 7 = 0 or m + 8 = 0

m = 7 or m = -8

Check each possible solution.

√(56 - 7) = 7--->√49 = 7 (true)

√(56 - (-8)) = -8--->√64 = -8 (false)

-8 is an extraneous solution, so the only solution of the given equation is 7.

The price of the bond is $1,043.98 (rounded to 2 decimal places).

To calculate the price of a five-year bond that has a coupon rate of 7.0% paid annually and a current market rate of 4.50%, we need to use the formula for the present value of a bond. A bond's value is the present value of all future cash flows that the bond is expected to produce. Here's how to calculate it:

Present value = Coupon payment / (1 + r)^1 + Coupon payment / (1 + r)^2 + ... + Coupon payment + Face value / (1 + r)^n

where r is the current market rate, n is the number of years, and the face value is the amount that will be paid at maturity. Since the coupon rate is 7.0% and the face value is usually $1,000, the coupon payment per year is $70 ($1,000 x 7.0%).

Here's how to calculate the bond's value:

Present value = [tex]$\frac{\$70 }{(1 + 0.045)^1} + \frac{\$70}{(1 + 0.045)^2 }+ \frac{\$70}{ (1 + 0.045)^3} + \frac{\$70}{ (1 + 0.045)^4 }+ \frac{\$70}{(1 + 0.045)^5} + \frac{\$1,000}{ (1 + 0.045)^5}[/tex]

For λ = 2:

(A - 2I)v = 0

|0 0 0| |x| |0|

|0 0 0| |y| = |0|

|0 0 1| |z| |0|

This implies that z = 0, and x and y can be any real numbers. An eigenvector corresponding to λ = 2 is v1 = (x, y, 0), where x and y are real numbers.

For λ = 3:

(A - 3I)v = 0

|-1 0 0| |x| |0|

|0 -1 0| |y| = |0|

|0 0 0| |z| |0|

This implies that x = 0, y = 0, and z can be any real number. An eigenvector corresponding to λ = 3 is v2 = (0, 0, z), where z is a real number.

Now, we need to normalize the eigenvectors to obtain an orthonormal basis.

A possible orthonormal basis for A is {v1/||v1||, v2/||v2||}, where ||v1|| and ||v2|| are the norms of the respective eigenvectors.

Finally, we can construct the diagonal matrix D using the eigenvalues on the diagonal in the same order as the orthonormal basis vectors. Thus, D = diag(2, 2, 3).

(b) Without the specific value for A^2, we cannot determine the diagonal matrix equivalent to A or find an orthonormal basis for diagonalization. The diagonal matrix would depend on the specific eigenvalues and eigenvectors of A^2. Therefore, we do not have enough information to provide the diagonal matrix or the orthonormal basis in this case.

Answer:

A straight line.

Step-by-step explanation:

[tex]3y = -2x + 12[/tex] on a coordinate plane is a line having slope [tex]\frac{-2}{3}[/tex] and y-intercept  [tex](0,4)[/tex] .

Firstly we try to find the slope-intercept form: [tex]y = mx+c[/tex]

m = slope

c = y-intercept

We have,   [tex]3y = -2x + 12[/tex]

=> [tex]y = \frac{-2x+12}{3}[/tex]

=> [tex]y = \frac{-2}{3} x +\frac{12}{3}[/tex]

=> [tex]y = \frac{-2}{3} x +4[/tex]

Hence, by the slope-intercept form, we have

m = slope = [tex]\frac{-2}{3}[/tex]

c = y-intercept = [tex]4[/tex]

Now we pick two points to define a line: say [tex]x = 0[/tex] and [tex]x=3[/tex]

When  [tex]x = 0[/tex] we have [tex]y=4[/tex]

When  [tex]x = 3[/tex] we have [tex]y=2[/tex]

Hence,  [tex]3y = -2x + 12[/tex] on a coordinate plane is a line having slope [tex]\frac{-2}{3}[/tex] and y-intercept  [tex](0,4)[/tex] .

By using a half-angle identity we find that the exact value of tan 15° is 2 - √3.

This can be found using the half-angle identity for the tangent, which states that tan(θ/2) = (1 - cos θ)/(sin θ). In this case, θ = 15°, so tan(15°/2) = (1 - cos 15°)/(sin 15°).

The half-angle identity for the tangent can be derived from the angle addition formula for the tangent. The angle addition formula states that tan(α + β) = (tan α + tan β)/(1 - tan α tan β). If we set α = β = θ/2, then we get the half-angle identity for a tangent: tan(θ/2) = (1 - cos θ)/(sin θ)

To find the exact value of tan 15°, we need to evaluate the expression (1 - cos 15°)/(sin 15°). The cosine of 15° can be found using the double-angle formula for cosine, which states that cos 2θ = 2 cos² θ - 1. In this case, θ = 15°, so cos 15° = 2 cos² 7.5° - 1.

The sine of 15° can be found using the Pythagorean identity, which states that sin² θ + cos² θ = 1. In this case, θ = 15°, so sin 15° = √(1 - cos² 15°).

Substituting these values into the expression for tan 15°, we get:

tan 15° = (1 - cos 15°)/(sin 15°) = (1 - 2 cos² 7.5° + 1)/(√(1 - cos² 15°)) = (2 - 2 cos² 7.5°)/(√(1 - cos² 15°))

The value of cos 7.5° can be found using the calculator. Once we have this value, we can evaluate the expression for tan 15°. The exact value of the given expression tan 15° is 2 - √3.
