the polygons are similar but not necessarily drawn to scale, find the value of x

The correct answer is (d) The price must be replaced with a relative price, and the marginal values must be replaced with the corresponding Marginal Rates of Substitution.

When the value of a public good cannot be expressed in monetary terms, the Samuelson condition still holds, but some modifications are required. In this case, the per-unit price (p) used in the Samuelson condition needs to be replaced with a relative price, which represents the trade-off between the public good and other goods or services. Additionally, the marginal values (MV) of the public good need to be replaced with the Marginal Rates of Substitution (MRS), which measure the rate at which one person is willing to substitute the public good for another good.

Therefore, to determine the efficient level of the public good, the modified Samuelson condition uses a relative price and the corresponding Marginal Rates of Substitution.

The adult male foot length of 25.9 cm is below the lower limit of 26.18 cm. Therefore, based on the range rule of thumb, the foot length of 25.9 cm is significantly low.

The range rule of thumb is a rough guideline for identifying significant values based on the standard deviation. According to this rule, a value is considered significantly low or significantly high if it falls outside the range of ±2 standard deviations from the mean.

Given the foot length data for adult males:

Mean (μ) = 28.44 cm

Standard Deviation (σ) = 1.13 cm

To determine the range for significantly low or significantly high values, we calculate:

Lower Limit = Mean - (2 × Standard Deviation)

Upper Limit = Mean + (2 × Standard Deviation)

Lower Limit = 28.44 - (2 × 1.13)

Upper Limit = 28.44 + (2 × 1.13)

Lower Limit = 28.44 - 2.26

Upper Limit = 28.44 + 2.26

Lower Limit ≈ 26.18 cm

Upper Limit ≈ 30.70 cm

According to the range rule of thumb, any foot length below 26.18 cm or above 30.70 cm would be considered significantly low or significantly high, respectively.

The adult male foot length of 25.9 cm is below the lower limit of 26.18 cm. Therefore, based on the range rule of thumb, the foot length of 25.9 cm is significantly low.

To make each table identical, we need to find the greatest common divisor (GCD) of 8 and 12, which will give us the maximum number of people that can be seated at each table.

We can find the GCD using the Euclidean algorithm:

12 = 8 × 1 + 4

8 = 4 × 2 + 0

Since the remainder is 0, the GCD of 8 and 12 is 4.

Therefore, the event planner can set up tables with 4 people at each table (2 adults and 2 children).

There are a total of 20 people (8 adults + 12 children), so the number of tables needed is:

20 ÷ 4 = 5

Thus, the greatest number of tables the planner can set up is 5.

Answer:

80

Step-by-step explanation:

First move like terms to one side:

x/2=25+15

Notice that the sign (+ or -) changes when we switch it to the opposite side

x/2=40

Multiply both sides by 2...

x=80

Answer:

x = 80

Step-by-step explanation:

\(\frac{x}{2}\) - 15 = 25 ( add 15 to both sides )

\(\frac{x}{2}\) = 40 ( multiply both sides by 2 to clear the fraction )

x = 40 × 2 = 80

The function f(x) = 4x³ - 51x² + 210x - 12 is concave downward on the interval (4.462, ∞).

To determine the intervals on which the function is concave downward, we need to analyze the second derivative of the function. The second derivative provides information about the concavity of the function.

First, let's find the second derivative of f(x). Taking the derivative of f(x) with respect to x, we get:

f'(x) = 12x² - 102x + 210

Now, taking the derivative of f'(x), we find the second derivative:

f''(x) = 24x - 102

To find the intervals of concavity, we need to find where f''(x) < 0.

Setting f''(x) < 0 and solving for x, we have:

24x - 102 < 0

Simplifying the inequality, we find:

24x < 102

Dividing by 24, we obtain:

x < 4.25

Therefore, the function is concave downward for x values less than 4.25. However, we also need to consider the domain of the function. The function f(x) = 4x³ - 51x² + 210x - 12 is defined for all real numbers. Thus, the interval on which the function is concave downward is (4.25, ∞).

Answer:

a is -2,1        b is -3,3        c is -1,3

Step-by-step explanation:

The other root of the given quadratic equation is a = ± 3/√2.

Given that, x=2 and x²+ax+12=0.

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.

Now, put x=2 in x²+ax+12=0 and find the value of a.

That is, 2²+2a+12=0

⇒4+12+2a=0

⇒16+2a=0

⇒2a=-16

⇒a=-8

So, the value of a is -8.

Put (0, 6) and (4, 6) in the function y=2x²+bx+c and find the value of b and c.

That is, 6=2(0)²+b(0)+c

⇒ c=6

6=2(4)²+b(4)+c

⇒ 6 = 32+4b+c

⇒ -26 = 4b + 6

⇒ 4b = -32

⇒ b = -8

So, the value of b is -8 and the value of c is 6.

Put x=a (root) in the equation 2x + x/a -9 = 0 and find the other root.

That is, 2a²+a/a -9 = 0

⇒ 2a² - 9 = 0

⇒ a²=9/2

⇒ a = ± 3/√2

Therefore, the other root of the given quadratic equation is a = ± 3/√2.

-x/100 = 0.999999...

Since the decimal 0.999999... is equal to 1, we can rewrite the equation as:

-x/100 = 1

Multiplying both sides by -100, we get:

x = -100

Therefore, -99.9999... is equal to the fraction -100.

(c) To convert 0.09090909... to a fraction, let x = 0.09090909....

Then, multiplying both sides by 100, we get:

100x = 9.090909...

The probability that A and B are in the same car is 1/1050.

If a group of 12 people is going to a concert on a Saturday night, and the group is taking three cars, each with four people, there is a possibility that the person A and B may be in the same car.

To determine the probability that A and B are in the same car, we need to determine how many ways the group of 12 people can be distributed among the three cars.

Since there are three cars, there are three different possibilities for where A and B can be located, i.e., in Car 1, Car 2, or Car 3.

There are three possible cars for A and B, and there are 2 people left to distribute among the other cars.

There are 10 ways to choose two people from the remaining 10, which means that there are 10 ways to place A and B into the same car.

After A and B have been placed in a car, the remaining 10 people can be placed in the other two cars.

The number of ways to distribute the 10 people into two cars with four and six people respectively is the same as the number of ways to choose four people from the 10 to be in the first car, or:10!/(4!6!) = 210.

Therefore, there are a total of 3 * 10 * 210 = 6300 different ways to distribute the group among the three cars.

Since there are 3 cars and 4 people in each car, there are a total of 3 * 2 * 1 = 6 ways to choose two people in the same car.

The probability that A and B are in the same car is therefore: P(A and B in same car) = 6/6300 = 1/1050.

The height of the pile is increasing at a rate of 16.72 feet per minute. To solve this problem, we need to use the volume formula for a right circular cone: V=pi/3 r²h. We know that the volume is 20 cubic feet per minute, the height is 14 feet and the radius of the base is 14 feet. So we can calculate the rate of change of the height by rearranging the formula to give v/(pi/3r²). So for our example, v/(pi/3*14²)=20/(pi/3*14²)=20/(3.14*196)=20/613.44=16.72 feet per minute.

To determine the mean and standard deviation from a histogram in MATLAB, you can use hist" function then "the mean" function then std" function.

1. Use the "hist" function to create the histogram.

2. Use the "mean" function to calculate the mean of the data.

3. Use the "std" function to calculate the standard deviation of the data.

1. Use the "hist" function to create the histogram. For example, "hist(x)" will create a histogram of the data in the vector "x".
2. Use the "mean" function to calculate the mean of the data. For example, "mean(x)" will return the mean of the data in the vector "x".
3. Use the "std" function to calculate the standard deviation of the data. For example, "std(x)" will return the standard deviation of the data in the vector "x".
So, if you have a vector "x" containing the data you want to analyze, you can use the following code to determine the mean and standard deviation:
hist(x);
mean_x = mean(x);
std_x = std(x);

This will create a histogram of the data, and calculate the mean and standard deviation. You can then use these values to further analyze the data.

The probability that a bridge hand will have exactly 2 queens is 0.45%.

To find the probability of getting a bridge hand with exactly 2 queens, we need to use the binomial probability formula. The formula is:

P(exactly k successes) = (n choose k) * p^k * (1-p)^(n-k)

Where:

n is the total number of trials

k is the number of successes in the trials

p is the probability of success in a single trial

In this case, the total number of trials is 13 (since a bridge hand consists of 13 cards), and the number of successes we want is 2 (since we want exactly 2 queens). The probability of success in a single trial is the probability of drawing a queen, which is 4/52 (since there are 4 queens in a deck of 52 cards).

Plugging these values into the formula, we get:

P(exactly 2 queens) = (13 choose 2) * (4/52)² * (48/52)¹¹

= (78) * (1/169) * (4/13)¹¹

= (4/169) * (4/13)¹¹

This simplifies to:

P(exactly 2 queens) = (4/169) * (4/13)¹¹

= (4/169) * (4/169)¹¹

= (4/169)¹²

The final probability is approximately 0.0045 or 0.45%. This means that the probability of getting a bridge hand with exactly 2 queens is quite low.
