Answer:

13/4096

Step-by-step explanation:

There are 12 ways the player can make 11 shots and miss one shot, and there is 1 way the player can make all shots, so there is a total of 13 ways that the player makes at least 11 out of 12 free throws.

The total number of possibilities for the free throws is 2^12 = 4096

Therefore, the probability that the player makes at least 11 out of 12 free throws is 13/4096

Without using a calculator, the trigonometric expressions simplify to:

1. sin^(-1)(sin(θ/6)) = θ/6

2. cos^(-1)(cos(5/4)) = 5/4

3. tan^(-1)(tan(5/6)) = 5/6.

To compute the trigonometric expressions without using a calculator, we can make use of the properties and relationships between trigonometric functions.

1. sin^(-1)(sin(θ/6)):

Since sin^(-1)(sin(x)) = x for -π/2 ≤ x ≤ π/2, we have sin^(-1)(sin(θ/6)) = θ/6.

2. cos^(-1)(cos(5/4)):

Similarly, cos^(-1)(cos(x)) = x for 0 ≤ x ≤ π. Therefore, cos^(-1)(cos(5/4)) = 5/4.

3. tan^(-1)(tan(5/6)):

tan^(-1)(tan(x)) = x for -π/2 < x < π/2. Thus, tan^(-1)(tan(5/6)) = 5/6.

Hence, without using a calculator, we find that:

sin^(-1)(sin(θ/6)) = θ/6,

cos^(-1)(cos(5/4)) = 5/4,

tan^(-1)(tan(5/6)) = 5/6.

Answer:

A. y=4x+1

steps-by-step explanation

The coordinates of the point on the unit circle at the angle of -45 degrees are (-√2/2, -√2/2). The angle of -45 degrees is measured clockwise from the positive x-axis, which means it is in the fourth quadrant of the unit circle.

To find the x-coordinate of the point on the unit circle at this angle, we use the cosine function: cos(-45) = √2/2. Since the point is in the fourth quadrant, the x-coordinate is negative, so we have x = -√2/2.

To find the y-coordinate, we use the sine function: sin(-45) = -√2/2. Again, since the point is in the fourth quadrant, the y-coordinate is also negative, so we have y = -√2/2.

Therefore, the coordinates of the point on the unit circle at the angle of -45 degrees are (-√2/2, -√2/2).

Let the amount deposited be x. It is assumed we are talking about simple interest.

After 4 years the interest amount is:

95% of this amount is Rs 4940:

Mrs Majhi deposited Rs 20000.

Mrs. Majhi deposited Rs 20000 in her bank account. This was calculated by first finding the total interest (before tax) and then using the formula for simple interest to determine the principal amount.

The question is based on the concepts of Simple Interest and taxation. We know that Mrs Majhi received Rs 4940 as net interest after 4 years and this amount is 95% of the total interest (since 5% was paid as income tax). The total interest can be calculated as (4940 / 95) * 100 = Rs 5200.

The rate of interest is given as 6.5% per annum. Thus, the money deposited (Principal) by her can be calculated using the formula for simple interest (I = PRT/100), where P is the Principal, R is the rate of interest, and T is the time. Re-arranged to calculate the Principal (P), it becomes P = I / (R*T) = 5200 / (6.5*4) = Rs 20000.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold.

Isaac has a 1/40 chance of winning the raffle, or a 2.5% chance. This indicates that he has a 2.5% probability of having his ticket chosen out of the 40 tickets that were sold. This is because there is only one raffle winner and it is impossible to predict which ticket will be picked.

It's also crucial to remember that his odds of winning are entirely independent of those of any other ticket holder; nobody else's ticket will affect the outcome of the raffle. As a result, Isaac has the same chance of winning as any other ticket holder. It's also vital to remember that regardless of how many tickets are sold, the likelihood of winning stays the same. Therefore, regardless of how many raffle tickets are sold, there is a 2.5% chance of winning.

The weighted average cost of capital (WACC) for company C is 6.63%.

The weighted average cost of capital (WACC) is a financial metric that represents the average rate of return a company must earn on its investments to satisfy its shareholders and creditors. It takes into account the proportion of debt and equity in a company's capital structure and the respective costs associated with each.

To calculate WACC, we need to consider the cost of debt and the cost of equity. The cost of debt is the interest rate a company pays on its debt, adjusted for taxes. In this case, the pre-tax cost of debt is 2% and the tax rate is 24%. Therefore, the after-tax cost of debt is calculated as (1 - Tax Rate) multiplied by the pre-tax cost of debt, resulting in 1.52%.

The cost of equity represents the return required by equity investors to compensate for the risk associated with owning the company's stock. Here, the cost of equity for company C is 6%.

The debt represents 10% of the total capital, while the equity represents the remaining 90%. To calculate the weighted average cost of capital (WACC), we multiply the cost of debt by the proportion of debt in the capital structure and add it to the cost of equity multiplied by the proportion of equity.

WACC = (Proportion of Debt * Cost of Debt) + (Proportion of Equity * Cost of Equity)

In this case, the calculation is as follows:

WACC = (0.10 * 1.52%) + (0.90 * 6%) = 0.152% + 5.4% = 6.552%

Therefore, the weighted average cost of capital (WACC) for company C is approximately 6.63%.

Step-by-step explanation:

After 15 years the population would be 176,000.

To find this answer, we simply find out what 4% of 110,000 is.

You can do this by entering in your calculator 110,000-96% (the remaining percentage) and that would give you a total of 4,400.

Next you need to multiply 4,400 by 15, which would give you a total answer of 66,000.

Lastly we add the numbers: 110,000 + 66,000 = 176,000

Scott's analysis of the impact of trade deficits on American jobs fails to consider the macroeconomic effects of trade deficits on domestic employment.

Irwin argues that Scott's analysis is incomplete as it ignores the long-term impact of trade deficits on employment. Scott's analysis is limited to looking at the short-term effect of trade deficits on the number of jobs lost or gained in certain industries.

He argues that trade deficits do not necessarily lead to a net loss of jobs in the economy, as the money saved by consumers through lower prices can be spent elsewhere, creating new jobs in other sectors.

However, Irwin argues that this analysis misses the bigger picture. Irwin suggests that trade deficits can lead to a long-term decline in the manufacturing sector, which can have significant negative consequences for domestic employment. Trade deficits can lead to a decrease in demand for domestically produced goods, as foreign competitors offer lower-priced alternatives. This can lead to a reduction in domestic production and employment in the affected industries.

Furthermore, Irwin argues that trade deficits can have a negative impact on the economy as a whole. Trade deficits can lead to a decrease in the value of the dollar, which can increase inflation and reduce consumer purchasing power. This, in turn, can lead to a decrease in demand for goods and services, which can negatively impact employment across multiple sectors.

In conclusion, Scott's analysis of the impact of trade deficits on American jobs is incomplete, as it fails to consider the long-term macroeconomic effects of trade deficits on domestic employment. Irwin argues that a full accounting of the impact of trade deficits on American jobs must take into account the potential negative consequences on the manufacturing sector and the economy as a whole.

Al plantear un sistema de ecuaciones lineales, encontramos que el número de obreros que contrató el ingeniero civil fue 50.

Para encontrar el número de obreros que el ingeniero contrató debemos plantear un sistema de ecuaciones lineales de dos ecuaciones con dos incógnitas, tal como sigue:

\( M - 1400*x = -8000 \)   (1)

\( M - 1200*x = 2000 \)   (2)

En donde:

M: es la incógnita igual al monto de dinero del ingeniero

x: es la incógnita igual al número de obreros

De la ecuación (1) tenemos:

\( M = 1400*x - 8000 \)   (3)

Podemos encontrar el valor de x (número de obreros), introduciendo la ecuación (3) en la ec (2):

\( 1400*x - 8000 - 1200*x = 2000 \)

\( 200*x = 10000 \)

\( x = 50 \)

El monto de dinero inicial del ingeniero sería entonces (ec 3):

\( M = 1400*50 - 8000 = 62000 \)

Por lo tanto, el número de obreros que contrató el ingeniero es 50.

The estimated current total cost for the installed and insulated tank is $12,065.73.

The first step is to calculate the surface area of the tank. The surface area of a cylinder is calculated as follows:

surface_area = 2 * pi * r * h + 2 * pi * r^2

where:

r is the radius of the cylinder

h is the height of the cylinder

In this case, the radius of the cylinder is 1 meter (half of the diameter) and the height of the cylinder is 1 meter. So the surface area of the tank is:

surface_area = 2 * pi * 1 * 1 + 2 * pi * 1^2 = 6.283185307179586

The insulation will add a thickness of 0.05 meters to the surface area of the tank, so the total surface area of the insulated tank is:

surface_area = 6.283185307179586 + 2 * pi * 1 * 0.05 = 6.806032934459293

The cost of the insulation is $40 per square meter and the cost of labor is $95 per square meter, so the total cost of the insulation and labor is:

cost = 6.806032934459293 * (40 + 95) = $1,165.73

The original cost of the tank was $10,900, so the total cost of the insulated tank is:

cost = 10900 + 1165.73 = $12,065.73

Therefore, the estimated current total cost for the installed and insulated tank is $12,065.73.

EXPLANATION

If the measure of ∠2= x+78 and the other ∠=40 degrees, by definition we know that sum of interior angles of a triangle is equal to 180 degrees.

Furthermore, we have two congruent legs, so this is an Isosceles triangle with two congruent angles (with the same measure).

Thus,

180 = 40 + 2* m∠2

Substituting m∠2 by the equation as follows:

180 = 40 + 2(x + 78)

Subtracting -40 to both sides:

180 - 40 = 2(x+78)

Simplifying:

140 = 2(x+78)

Dividing both sides by 2:

140/2 = x + 78

Simplifying:

70 = x + 78

Subtracting -78 to both sides:

70 - 78 = x

Simplifying:

-8 = x

Switching:

x = -8
