The given equation 3x + 7y = 11 is equal to (1,-2).

The given equation is 3x + 7y = 11.

To find the solution of the equation, we need to consider the given options:

(6,-1)(1,-2)(0,4)

Now substitute each value of x and y in the given equation, we get,

If x = 6 and y = -13(3 × 6) + (7 × -1) = 18 - 7 = 11 ≠ 11

If x = 1 and y = -2(3 × 1) + (7 × -2) = 3 - 14 = -11 ≠ 11

If x = 0 and y = 4(3 × 0) + (7 × 4) = 0 + 28 = 28 ≠ 11

Therefore, the given equation 3x + 7y = 11 is equal to (1,-2).

Based on the mean and standard deviation of men's heights at that time, the tallest living man had a more extreme height compared to the shortest living man.

The question asks which of the two men, the tallest living man or the shortest living man at that time, had a height that was more extreme.

To determine this, we need to compare their heights to the mean and standard deviation of men's heights at that time.

The mean height of men at that time was 177.71 cm, and the standard deviation was 6.03 cm.

The tallest living man had a height of 237 cm, which is 59.29 cm above the mean (237 - 177.71 = 59.29).

The shortest living man had a height of 139.5 cm, which is 38.21 cm below the mean (177.71 - 139.5 = 38.21).

To determine which height is more extreme, we can compare the distance from each height to the mean.

The distance from the tallest man's height to the mean is 59.29 cm, while the distance from the shortest man's height to the mean is 38.21 cm.

Since the distance from the tallest man's height to the mean is greater than the distance from the shortest man's height to the mean,  we can conclude that the tallest living man had the height that was more extreme.

In summary, based on the mean and standard deviation of men's heights at that time, the tallest living man had a more extreme height compared to the shortest living man.

From the given information provided, emily and john should drink 56.7 cups of water for 42 hours hiking.

If hikers should drink 2.7 cups of water for every 2 hours of hiking, then we can use a proportion to find how much water Emily and John should drink over their 42-hour hike:

2.7 cups / 2 hours = x cups / 42 hours

To solve for x, we can cross-multiply:

2.7 cups × 42 hours = 2 hours × x cups

113.4 cups = 2x

Finally, we can divide both sides of the equation by 2 to solve for x:

x = 56.7 cups

Therefore, Emily and John should drink a total of 56.7 cups of water during their 42-hour hike.

This expression represents the probability of a policyholder filing more than one claim during the three-year period under the given assumption.

Given that P(n) represents the probability that the policyholder files n claims during the three-year period, we want to find the probability that a policyholder files more than one claim. In other words, we need to calculate the probability of a policyholder filing 2 or more claims.

Since probabilities of all possible outcomes must sum up to 1, we can write:
P(0) + P(1) + P(2) + P(3) + ... = 1

We are looking for the probability of filing more than one claim, which can be written as:
P(2) + P(3) + P(4) + ...

We can calculate this by subtracting the probabilities of filing 0 or 1 claim from the total probability (1):
Probability of filing more than one claim = 1 - P(0) - P(1)

Since the problem doesn't provide specific values for P(0) and P(1), the final answer is:
Probability of filing more than one claim = 1 - P(0) - P(1)

Angles p and q are complementary, which means that their sum is equal to 90 degrees. Let's assume the size of angle q is x degrees. Since p is four times the size of q, we can write the equation p = 4q.

To find the size of q, we need to substitute the value of p in terms of q into the equation for the sum of the angles: p + q = 90.

Substituting 4q for p, we get:

4q + q = 90

Combining like terms:

5q = 90

To solve for q, we divide both sides of the equation by 5:

q = 90/5

Simplifying:

q = 18

Therefore, the size of angle q is 18 degrees.

when angles p and q are complementary and p is four times the size of q, the size of angle q is 18 degrees.

The area of the surface formed by revolving the polar equation r = 2 cos θ over the interval 0 ≤ θ ≤ π/2 about the polar axis is 2π.

To find the area, we first need to express the polar equation in terms of Cartesian coordinates.

Using the formula x = r cos θ and y = r sin θ, we get x = 2cosθ cosθ and y = 2cosθ sinθ.

Next, we find the partial derivatives of x and y with respect to θ, which are -2sinθcosθ and 2cos²θ - 2sin²θ, respectively.

Using the formula for the surface area of a surface of revolution, which is given by A = ∫2πf(θ)√[r² + (f'(θ))²]dθ, we

substitute the values we have obtained into the formula to get A = ∫0^π/2 2π|sinθ|√[4cos²θ]dθ.

Simplifying this expression and integrating, we get A = 2π. Therefore, the area of the surface formed by revolving the polar equation r = 2 cos θ over the interval 0 ≤ θ ≤ π/2 about the polar axis is 2π.

Answer:

Answer: x = 33, y = 81..........

You can see that the two lateral and vertical sides of the quadrilateral are congruent respectively, meaning that ∠3x = ∠(2x+33).

You also know that 3x + y = 180° since they're supplementary.

To solve for x, just solve the equation I wrote above:

3x = (2x+33)    (subtract 2x from both sides, and that automatically gives you

x = 33               the value)

To solve for y, plug it into the second equation I provided:

3(33) + y = 180

99 + y = 180

y = 81

∴ x = 33, y = 81

For a taxable income of $1,80,900, the effective tax rate is 21.11%.

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

The correct option regarding the amount of coins is given as follows:

c 4 nickels, 10 dimes, 4 quarters

The amounts are obtained by a system of equations, for which the variables are given as follows:

Amy has 18 coins consisting of nickels, dimes, and quarters, hence:

x + y + z = 18.

She has the same amount of nickels as quarters, hence:

x = z.

Thus:

2x + y = 18

y = 18 - 2x.

She has a total of $2.20 worth of coins, hence:

0.05x + 0.1y + 0.25z = 2.2

0.3x + 0.1y = 2.2

Since y = 18 - 2x, the value of x is obtained as follows:

0.3x + 0.1(18 - 2x) = 2.2

0.1x = 0.4

x = 0.4/0.1

The quadratic function with the given features is defined as follows:

y = 0.86x² - 5.86x + 5.

The standard definition of a quadratic function is given as follows:

y = ax² + bx + c.

When x = 0, y = 5, hence the coefficient c is given as follows:

c = 5.

Hence:

y = ax² + bx + 5.

When x = 1, y = 0, hence:

a + b + 5 = 0

a + b = -5.

The discriminant is given as follows:

D = b² - 4ac.

Hence:

D = b² - 20a

The minimum value is of -4, hence:

-D/4a = -5

(b² - 20a)/4a = -5

b² - 20a = 20a

b² = 40a

Since a = -5 - b, we have that the value of b is obtained as follows:

b² = 40(-5 - b)

b² + 40b + 200 = 0.

b = -5.86.

Hence the value of a is of:

a = -5 + 5.86

a = 0.86.
