Natural numbers are strictly only plain numbers like no percents or integers, such as 1, 2, 3, 4, 5, 6 etc. Natural numbers are whole numbers and positive, so 0 would not be considered natural since it is not positive or negative

Rational numbers are numbers like 1, -100, .33, -10000, 2.4, etc it can be ALMOST anything, rational numbers fit every category but one IRRATIONAL

Irrational numbers are numbers like pie (3.145.......) it goes on forever and ever if the number never stops and repeats its called a repeating decimal, (HUGE TIP, IF YOU CAN MAKE IT A FRACTION IS IS ALMOST ALWAYS RATIONAL)

Answer: y = -3/5x - 6

Step-by-step explanation:

There are a few equations that can be used for this, but the simplest one would be y = mx + b

We are given:

y = -3

m = -3/5 (slope)

x = -5

b = ?

Our equation is this, we are solving for b

==> -3 = -3/5 ( -5) + b

==> -3 = -3/5 ( -5) + b ( multiply the brackets)

==> -3 = 3 + b ( subtract 3 to both sides)

==> -6 = b

Now we can make the desired equation in slope intercept form;

y = -3/5x - 6

Hope this helped! Have a great day :D

Answer:

Let men = m

let women = w

Seven times number of men = 7m

5 more than 7 times the number of men = 7m + 5

w = 7m + 5

w - 5 = 7m + 5 - 5

w - 5 = 7m

\(m = (\frac{w - 5}{7} )\)

If two methods agree perfectly in a method comparison study, the slope equals 1.0 and the y-intercept equals 0.0. Therefore, option (b) is the correct answer.

In a method comparison study, the goal is to compare the agreement between two different measurement methods or instruments. The relationship between the measurements obtained from the two methods can be described by a linear equation of the form y = mx + b, where y represents the measurements from one method, x represents the measurements from the other method, m represents the slope, and b represents the y-intercept.

When the two methods agree perfectly, it means that there is a one-to-one relationship between the measurements obtained from each method. In other words, for every x value, the corresponding y value is the same. This indicates that the slope of the line connecting the measurements is 1.0, reflecting a direct proportional relationship.

Additionally, when the two methods agree perfectly, there is no systematic difference or offset between the measurements. This means that the line connecting the measurements intersects the y-axis at 0.0, indicating that the y-intercept is 0.0.

Therefore, in a perfect agreement scenario, the slope equals 1.0 and the y-intercept equals 0.0, which corresponds to option (b).

Step-by-step explanation:

Both descriptive and inferential statistics are important branches of statistics and serve different purposes. Descriptive statistics is used to describe and summarize data, while inferential statistics is used to make predictions and draw conclusions about a population based on a sample of the data.

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It helps in making informed decisions based on the data and provides insights into the data. There are two main branches of statistics: descriptive statistics and inferential statistics.

Descriptive statistics is used to describe and summarize the data. It involves collecting, organizing, analyzing, and interpreting data in a meaningful way. Descriptive statistics help to present the data in a way that is easy to understand and interpret. It includes measures such as mean, median, mode, and standard deviation. For example, if we have a data set of heights of students in a class, we can use descriptive statistics to find the average height of students, which will give us a better understanding of the data.Inferential statistics, on the other hand, involves making inferences and predictions about a population based on a sample of the data. It helps in drawing conclusions and making decisions about a population based on a sample. Inferential statistics uses statistical models and hypothesis testing to make predictions and draw conclusions about the population. For example, if we have a sample of 100 students from a class of 1000 students and we want to know the average height of all the students in the class, we can use inferential statistics to make an estimate based on the sample data.

========================================================

Explanation:

The given table looks like this

\(\begin{array}{|c|c|} \cline{1-2}\text{number of rolls} & \text{number of people}\\\cline{1-2}1 & \\\cline{1-2}6 & 3\\\cline{1-2}10 & \\\cline{1-2}16 & \\\cline{1-2}25 & \\\cline{1-2}n & \\\cline{1-2}\end{array}\)

Focus on the row that has two values in it.

x = number of rolls = 6

y = number of people 3

k = constant of proportionality

y = kx

k = y/x = 3/6 = 0.5

The constant of proportionality is k = 0.5 which gives the direct variation equation of y = 0.5x

If x = 1, then y = 0.5*1 = 0.5 meaning that 1 roll feeds 0.5 people. This means we need 2 rolls to feed one person.

If x = 10, then y = 0.5x = 0.5*10 = 5 people can be fed with those 10 rolls. This process is continued until we finish filling out the table.

Step-by-step explanation:

Answer:

Equilateral Acute Triangle

Step-by-step explanation:

The side labeled "a" is made the longer side. These are the two congruent sides. So a > b.

We are told that the longer side is 6.3, so a = 6.3, meaning that

2a+b = 15.7

2(6.3)+b = 15.7

12.6+b = 15.7

b = 15.7-12.6

b = 3.1

The triangle has sides of: 6.3, 6.3, 3.1

The perimeter is 6.3+6.3+3.1 = 15.7

To calculate the discharge through the circular channel, we can use Manning's equation, which relates the flow rate (Q) to the channel properties and flow conditions. Manning's equation is given by:

Q = (1/n) * A * R^(2/3) * S^(1/2)

where:

Q is the discharge (flow rate)

n is Manning's coefficient (0.014 in this case)

A is the cross-sectional area of the channel

R is the hydraulic radius of the channel

S is the slope of the channel bed

First, let's calculate the cross-sectional area (A) of the circular channel. The diameter of the channel is given as 6m, so the radius (r) is half of that, which is 3m. Therefore, the area can be calculated as:

A = π * r^2 = π * (3m)^2 = 9π m^2

Next, let's calculate the hydraulic radius (R) of the channel. For a circular channel, the hydraulic radius is equal to half of the diameter, which is:

R = r = 3m

Now, we can calculate the slope (S) of the channel bed. The given slope is 1 in 600, which means for every 600 units of horizontal distance, there is a 1-unit change in vertical distance. Therefore, the slope can be expressed as:

S = 1/600

Finally, we can substitute these values into Manning's equation to calculate the discharge (Q):

Q = (1/0.014) * (9π m^2) * (3m)^(2/3) * (1/600)^(1/2)

Using a calculator, the discharge can be evaluated to get the final result.

The probability that the mean length of the sample rods would be less than 164. 56 millimeters is 0.8790

We need to standardize the sample mean using the formula:

z = (x - μ) / (σ / √(n))

Where:

x = sample mean

μ = population mean

σ = population standard deviation

n = sample size

In our case, x = 164.56 millimeters, μ = 164 millimeters, σ = √(121) = 11 millimeters, and n = 287. Plugging these values into the formula, we get:

z = (164.56 - 164) / (11 / √(287)) = 1.170

Now we need to find the probability that the standardized sample mean is less than 1.170. We can use a standard normal distribution table or a calculator to find this probability. The area under the standard normal curve to the left of 1.170 is 0.8790.

Therefore, the probability that the mean length of the sample rods is less than 164.56 millimeters is 0.8790, rounded to four decimal places.

The probability of an individual buying the product given they have seen the ad is 0.10. The probability of an individual buying the product given they have not seen the ad is 0.05. Therefore, the probability of an individual having seen the ad given they have bought the product is 0.83, rounded to 3 decimal places.

The probability of an individual buying the product given they have seen the ad is 0.10, which means that 10% of individuals who have seen the ad will buy the product. The probability of an individual buying the product given they have not seen the ad is 0.05, which means that 5% of individuals who have not seen the ad will buy the product. Therefore, the probability of an individual having seen the ad given they have bought the product is the ratio of the two. This can be expressed as the probability of an individual having seen the ad given they have bought the product divided by the probability of an individual having not seen the ad given they have bought the product. This can be calculated as (0.80/0.10) / (1-0.80/0.05) = 0.83, rounded to 3 decimal places. This implies that there is an 83% probability that an individual has seen the ad if they have bought the product. This is because 80% of people have seen the television ads for the product, and only 10% of those who have seen the ad buy the product, whereas only 5% of those who have not seen the ad buy the product.

The equation of the circle with center (4, 9) and radius 4 is (x - 4)^2 + (y - 9)^2 = 16.

The general equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

In this case, the given center is (4, 9) and the radius is 4. Plugging these values into the equation, we have:

(x - 4)^2 + (y - 9)^2 = 4^2

Simplifying, we get:

(x - 4)^2 + (y - 9)^2 = 16

Therefore, the equation of the circle with center (4, 9) and radius 4 is (x - 4)^2 + (y - 9)^2 = 16.
