Answer:

For the first one the slope is 4

For the second one the slope is 0

Step-by-step explanation:

Subtract 4x from both sides of the equation

-y=6-4x

Multiply each step in -y=6-4x by -1

y=-6+4x

For slope intercept form y=mx+b or y=4x+6

Slope : 4

Y intercept is (0,6)

To find the x intercept substitute in 0 for y and solve for x. To find the y intercept substitute in 0 for x and solve for y

X intercept: (9/5, 0)

Y intercept: (0,-9)

Slope is 0 using the formula y=mx+b

Step-by-step explanation:

If g(x) = -5x - 4 and g(x) = 1 then -5x - 4 = 1.

Given this, we can now solve for x by adding 4 to both sides and then dividing both sides by -5 to isolate the value of x.

                                -5x-4=1

                            -5x-4+4=1+4

                                -5x=5

Problem to solve:

if the data is skewed or otherwise biased, the least squares line may not accurately represent the true relationship between the number of stories and building height.

The estimated height of a building with six stories would depend on the average height of each story, which can vary depending on the building's design and construction materials. However, a general rule of thumb is that each story in a building is typically between 10 and 14 feet in height, which would put a six-story building between 60 and 84 feet tall.

As for whether the least squares line gives an accurate estimate of height, that would depend on the data being used to generate the line. The least squares method is a statistical technique used to find the line of best fit for a set of data points, with the goal of minimizing the sum of the squared distances between each data point and the line.

If the data used to generate the line is representative of the population of buildings with six stories, then the least squares line should provide a reasonably accurate estimate of height. However, if the data is skewed or otherwise biased, the least squares line may not accurately represent the true relationship between the number of stories and building height. Therefore, it is important to carefully examine the data and consider potential biases before using the least squares method to make predictions.

Answer:

The total number of winners is 17.

Step-by-step explanation:

Let's assume that the number of winners is "x". Then the number of participants who did not win is "45 - x".

The amount of money awarded to the winners is 1000x rupees.

The amount of money awarded to the participants who did not win is 200(45 - x) rupees.

According to the question, the total amount of prize money distributed is 22600 rupees. So we can write:

\(\sf\implies 1000x + 200(45 - x) = 22600 \)

Simplifying this equation:

\(\sf\implies 1000x + 9000 - 200x = 22600 \)

\(\sf\implies 800x = 13600 \)

\(\sf\implies x = 17 \)

Therefore, the total number of winners is 17.

In order for a 22% probability that a gallon of gas costs less than 1.80, the standard deviation have to be 39.21 cents.

Given data,

The average retail price of gasoline (all types) for the first half of 2005 was 212.2 cents.

Round z-value calculations to two decimal places and final answer to the nearest cent.

Method First, we have to calculate the z-value of 1.80.

Mean = 212.2 cents Standard deviation = ?

Value = 180 cents

Z = (x - μ) / σ

where, x = 180

μ = 212.2

σ = standard deviation of price distribution

Z = (180 - 212.2) / σ0.22 = P(z < (180 - 212.2) / σ)From standard normal distribution table (attached),

P(z < 0.84) = 0.7995.0.22 = 0.7995(180 - 212.2) / σσ = (180 - 212.2) / (0.22 × 0.7995)σ = 39.21 cents

Hence, the standard deviation have to be 39.21 cents in order for a 22% probability that a gallon of gas costs less than 1.80.

The slope of the line is -294/25 and the y-intercept is -294/25.

To find the equation of the line through (7,6) that cuts off the least area from the first quadrant, we need to minimize the product of the x and y intercepts.

Let the x-intercept be a and the y-intercept be b. Then the equation of the line is:

y = (-b/a)x + b

The product of the intercepts is ab = b(-6/b) = -6.

To minimize this product, we need to find the values of a and b that satisfy the constraint that the line passes through (7,6).

Substituting y = 6 and x = 7 in the equation of the line, we get:

6 = (-b/a)7 + b

Solving for b, we get:

b = 42/(a+7)

Substituting this value of b in the equation ab = -6, we get:

a(42/(a+7)) = -6

Simplifying, we get:

42a = -6(a+7)

48a = -42

a = -7/8

Substituting this value of a in the equation b = 42/(a+7), we get:

b = 294/25

Therefore, the equation of the line is:

y = (-294/25)x - 294/25

The slope of the line is -294/25 and the y-intercept is -294/25.

The equation in standard form of the line passing through the points (2, -3) and (4, 2) is 5x - 2y = 16.

To find the equation of a line in standard form, we need to determine the slope of the line and one point on the line. Given the points (2, -3) and (4, 2), we can calculate the slope using the formula:

slope (m) = \(\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)

Using the coordinates (2, -3) and (4, 2), the slope is calculated as follows:

m = \(\frac{2-(-3)}{4-2}\) = 5/2

Now that we have the slope, we can choose one of the points, let's say (2, -3), and use the point-slope form to find the equation of the line:

y - y1 = m(x - x1)

Plugging in the values, we have:

y - (-3) = \(\frac{5}{2} (x-2)\)

y + 3 = \(\frac{5}{2} (x-2)\)

Expanding and rearranging the equation, we get:

2y + 6 = 5x - 10

5x - 2y = 16

Therefore, the equation in standard form of the line passing through the points (2, -3) and (4, 2) is 5x - 2y = 16.

We can say that the sampling plan leads to non-response bias; because the customers who did not participate in the survey would have provided significantly different answers.

Non-response is a description of non-observation appear in most surveys, that means failure to provide a measurement on one or more research variables for one or more elements chosen for the survey.

Non-response bias happens when participants in the survey are unable or unwilling to respond to a survey question or even the whole survey. Reasons for non-response may vary from person to person. To be considered a disposition of bias, a source of error has to be systematic in nature. Non-response bias is not an anomaly to this rule.

There are 30 different combinations of two members who can be selected to serve on the spring formal committee.

Permutation is the arrangement of elements in a specific order. In this scenario, the elements are the six members of the student council, and the order in which they are arranged is important.

To find the number of permutations, we use the formula nPk, where n is the number of elements and k is the number of elements we want to arrange.

In this case, n = 6 and k = 2,

so we have

=> 6P2 = 6!/(6-2)!

=> 6!/(4!) = 6 x 5/1 = 30.

Relational databases are heavily based on the mathematical concept of: Set Theory. The correct option is (A).

Relational databases are based on the principles of set theory, which deals with sets of elements and their relationships with each other. In a relational database, data is organized into tables, with each table representing a set of related data.

The tables are then related to each other through the use of keys, which allow for the establishment of relationships between different sets of data. The principles of set theory also govern the use of operations such as union, intersection, and difference, which can be used to manipulate the data in the tables.

Therefore, the mathematical concept of set theory is a fundamental part of the design and use of relational databases.

In order to find the measures in the circle shown, recall that according to the inscribed angle theorem, the measure of intercepted arc is equal to the central angle, but is twice the measure of the inscribed angle.

1. m<PSQ = m<PAQ

Substitute:

m<PSQ = 130°

2. Find m<PBQ:

m<PBQ = 1/2(m(PQ) + m(RS)) [based on the angles of intersecting chords theorem]

Substitute:

m<PBQ = 1/2(130 + 2(35))

m<PBQ = 100°

m<AQS = 180 - [m<BAQ + m<PBQ]

Substitute:

m<AQS = 180 - [(180 - 130) + 100]

m<AQS = 30°

3. m(QR) = m<QAR

Substitute:

m(QR) = 100°

If you want to plot these by hand, it is convenient to write them in slope-intercept form:

  y = -2x +3 . . . . . subtract 2x from both sides of the first equation

  y = x . . . . . . . . . add y to both sides of the second equation

These tell you the first line goes through (0, 3) with a slope of -2. The second line goes through the origin with a slope of +1.

The solution is ...

  (x, y) = (1, 1)

_____

Additional comment

Slope-intercept form is not the only convenient form for graphing the equation of a line. The first equation, for example, is given in standard form, which makes it easy to see the x-intercept is 3/2, and the y-intercept is 3. Sometimes plotting points with a fractional coordinate can be problematical, so we choose to put that equation into a different form.

The second equation quite clearly tells us y=x, so we know that line goes through points that have the same x- and y-coordinates.

The probability that a student who has an A is a male is 60%.

To find the probability that a student who has an A is a male, we need to calculate the ratio of the number of male students with an A to the total number of students with an A.

Given that there are 19 students in total, and 6 of them are female, we can determine that there are 19 - 6 = 13 male students. Out of these male students, 7 do not have an A. Therefore, the number of male students with an A is 13 - 7 = 6.

Now, we know that there are 10 students in total who have an A. Therefore, the probability that a student with an A is a male can be calculated as the ratio of the number of male students with an A to the total number of students with an A:

Probability = Number of male students with an A / Total number of students with an A

Probability = 6 / 10
