Answer:

5/12

Step-by-step explanation:

total number of marble is 12 total number of blu is 5

Answer:

12.5%

Step-by-step explanation:

you have 7 reds of 14 total.

the 1st marble has 7 of 14 probability of being red

the 2nd has 6 of 13 of being red

the 3rd has 5 of 12 of being red

multiplying this out you have:

(7/14)*(6/13)*(5/12)=210/2184

THAT will condense down to 5/52 or 9.615%

this does assume not placing the balls back in between draws

if you do put them back in between draws you would have 7 of 14 chance each draw

that would give you by multiplying out

(7/14)*(7/14)*(7/14)=343/2744

that condenses to 1 of 8 or 12.5%

Median of weight of the bags of potatoes if a 60-pound bag was included in the list is 28 pounds.

How to find median?

If the number of observations is odd, the number in the middle of the list is the median. This can be found by taking the value of the (n+1)/2 -th term, where n is the number of observations.

Else, if the number of observations is even, then the median is the simple average of the middle two numbers.

According to the given question:

List of weights for 6 bags of potatoes is 21, 28, 32, 25, 40, 24.

Median weight of the bags of potatoes is 26.5 pounds.

If a 60-pound bag was included in the list, the new list will be

21, 28, 32, 25, 40, 24, 60

Arranging the list in ascending/descending order

21, 24, 25, 28, 32, 40, 60

Now, the number of terms is odd

        ∴ Median = (n+1)/2 th term

                         = (7+1)/2 th term

                         = 8/2 th term

                         = 4 th term

                         = 28 pounds

Hence Median of weight of the bags of potatoes if a 60-pound bag was included in the list is 28 pounds.

.

The system of equations given by kx + 9y = 1 will have a unique solution for all values of k except k = 0.

To determine the values of k for which the system has a unique solution, we need to consider the coefficient of the x-variable, which is k. For a unique solution, the coefficient k should not be equal to zero.

If k = 0, the equation becomes 0x + 9y = 1, which simplifies to 9y = 1. This equation represents a line parallel to the x-axis, and any value of y will satisfy it. Therefore, there is no unique solution in this case.

For all values of k that are not equal to zero, the system will have a unique solution because the x-variable will have a non-zero coefficient, allowing us to uniquely determine its value based on the given equation.

Hence, the correct answer is (A) All k ≠ 0.

The dimensions that minimize the cost are x ≈ 13.42 ft and y ≈ 33.58 ft.

We are given that;

Brick wall costing= $30

Area= 450ft^2

Now,

To find the critical points, we take the derivative of C and set it equal to zero:

C’ = 50 - 9000/x2 C’ = 0 50 - 9000/x2 = 0 9000/x2 = 50 x2 = 9000/50 x2 = 180 x = ±√180 x ≈ ±13.42

Since x must be positive, we only consider x ≈ 13.42 as a critical point. To check if this is a minimum or maximum, we can use the first derivative test or the second derivative test. Using the second derivative test, we find:

C’’ = 18000/x3

Since x ≈ 13.42 is positive, C’’ > 0 at this point, which means C has a local minimum at x ≈ 13.42.

To find the absolute minimum, we also need to evaluate C at the endpoints of its domain:

C(0) = undefined C(450) = 50(450) + 20(1) = 22520

So, C has an absolute minimum at x ≈ 13.42 with a value of:

C(13.42) ≈ 50(13.42) + 20(33.58) ≈ $1,337

To find the dimensions of the garden that minimize the cost, we use y = 450/x and plug in x ≈ 13.42:

y ≈ 450/13.42 y ≈ 33.58

Therefore, by area the answer will be x ≈ 13.42 ft and y ≈ 33.58 ft.

According the question The approximate probability that more than 200 out of 500 people will be against increasing taxes is approximately 0.0114 or 1.14%.

Given:

- Sample size (n) = 500

- Probability of being against increasing taxes (p) = 0.35

- Probability of being in favor of increasing taxes (q) = 1 - p = 0.65

Mean (μ) and standard deviation (σ) of the binomial distribution:

\(\[\mu = n \cdot p = 500 \cdot 0.35 = 175\]\)

\(\[\sigma = \sqrt{n \cdot p \cdot q} \approx \sqrt{500 \cdot 0.35 \cdot 0.65} \approx 10.95\]\)

To find the probability of more than 200 people being against increasing taxes, we can use the normal approximation to the binomial distribution. Let's calculate the Z-score:

\(\[Z = \frac{{X - \mu}}{{\sigma}} = \frac{{200 - 175}}{{10.95}} \approx 2.28\]\)

Using a standard normal distribution table or calculator, we find that the probability of \(Z > 2.28\) is approximately 0.0114.

Therefore, the approximate probability that more than 200 out of 500 people will be against increasing taxes is approximately 0.0114 or 1.14%.

Data set (ii) because it has two entries that are far from the mean. the deviations from the mean are smaller,

The sample standard deviation measures the dispersion or spread of data points in a data set. To determine which data set has the greatest sample standard deviation, we need to consider the distribution of values relative to the mean.

In data set (ii), which has two entries that are far from the mean, the presence of these outliers can significantly increase the sample standard deviation. Outliers are data points that deviate significantly from the majority of the data, and their inclusion in a data set can inflate the standard deviation.

This is because the standard deviation calculates the average distance between each data point and the mean, and outliers contribute to larger distances.

Data set (i), on the other hand, having more entries that are close to the mean, suggests a more concentrated or clustered distribution of values.

When data points are closer to the mean, the deviations from the mean are smaller, resulting in a smaller standard deviation compared to a data set with outliers.

Data set (iii), with more entries that are farther away from the mean, may also have a higher sample standard deviation. However, without specific information about the magnitude of these deviations and the overall distribution of values,

we cannot definitively conclude that data set (iii) has the greatest standard deviation. Therefore, based on the information provided, the data set (ii) with two entries that are far from the mean is likely to have the greatest sample standard deviation.

The ratio of dividends to the average number of common shares outstanding is known as the dividend yield. It is a measure of the return on an investment in the form of dividends received relative to the number of shares held.

To calculate the dividend yield, you need to divide the annual dividends per share by the average number of common shares outstanding during a specific period. The annual dividends per share can be obtained by dividing the total dividends paid by the number of outstanding shares. The average number of common shares outstanding can be calculated by adding the beginning and ending shares outstanding and dividing by 2.

For example, let's say a company paid total dividends of $10,000 and had 1,000 common shares outstanding at the beginning of the year and 1,500 shares at the end. The average number of common shares outstanding would be (1,000 + 1,500) / 2 = 1,250. If the annual dividends per share is $2, the dividend yield would be $2 / 1,250 = 0.0016 or 0.16%.

In summary, the ratio of dividends to the average number of common shares outstanding is the dividend yield, which measures the return on an investment in terms of dividends received per share held.

The region is bounded by the x-axis x=0, x=2pi*/3 and y= 3sin(x/2)   is pi/3.

To find the area of region r, we first need to sketch the region on the x-y plane. From the given information, we know that the region is bounded by the x-axis, the line x=0, the line x=2pi/3, and the curve y=3sin(x/2). To sketch the curve, we can start by noting that sin(x/2) is a periodic function with period 2pi. This means that the curve will repeat itself every 2pi units on the x-axis. We can also note that sin(x/2) is non-negative for x in the interval [0, 2pi], which means that the curve will lie above the x-axis in this interval. To sketch the curve in the interval [0, 2pi/3], we can use the fact that sin(x/2) is increasing on this interval. This means that the curve will start at the point (0,0) and increase until it reaches its maximum value of 3sin(pi/6) = 3/2 at x=pi/3. The curve will then decrease until it reaches the x-axis at x=2pi/3.
Using this information, we can sketch the region r as a triangle with base 2pi/3 and height 3/2. The area of this triangle is given by:
area = 1/2 * base * height = 1/2 * (2pi/3) * (3/2) = pi/3
