plug the givwn values in the equatiom y=mx+b

y = -2/9x -10

ANSWER: \(y = \frac{-2}{9} x - 10\)

EXPLANATION:

1. Know what the slope-intercept form is:

\(y = m x + b\)

where:

\(y = ycoordinate\\m = slope\\x = x coordinate\\b = y intercept\)

2. Plug in what you know

\(y = \frac{-2}{9} x + (-10)\)

+ and - is equal to - so

\(y = \frac{-2}{9} x - 10\)

Answer:

1. Coordinates of the other endpoint are (13, -10)

2. Coordinates of the other endpoint are: (8, 8)

Step-by-step explanation:

1. The endpoint (-9, 8) is located in the second quadrant. The midpoint (2, -1) is located in the fourth quadrant. That is to the right and down from the endpoint. Notice that the difference in the horizontal axis between the x-coordinates of the endpoint (-9, 8) and the midpoint (2, -1) is: | 2 - (-9) | = 11

And the difference in the vertical axis is: | -1 - 8 | = 9

So the midpoint is located 11 units to the right,and 9 units down from the endpoint. Then the other endpoint should be located also 11 units to the right, and 9 units down but from the midpoint. That is at: (2 + 11, -1 - 9) = (13, -10)

2. In this case, both, endpoint and midpoint are in the first quadrant, but notice that the midpoint is further away from the origin of coordinates.

The differences now are:

horizontal: 4 - 0 = 4

vertical: 5 - 2 = 3

and in both cases units are added to the endpoint coordinates to get to the midpoint coordinate values.

So to find the other endpoint we add 4 units to the x-value of the midpoint, and add 3 units to its y-value:

Other endpoint at : ( 4 + 4, 5 + 3) = (8, 8)

The integral we get: ∬dxyda = ∫[0,2] (x\((6-3x/2)^{2/2}\))dx

To evaluate the double integral ∬dxyda over the triangular region D with vertices (0,0), (2,0), and (0,6), we need to set up the integral in terms of x and y and determine the bounds of integration.

Since D is a triangular region, we can express it as follows:

0 ≤ x ≤ 2

0 ≤ y ≤ 6 - 3x/2

We need to integrate the function xy with respect to both x and y over the given bounds.

The double integral can be written as:

∬dxyda = ∫[0,2]∫[0,6 - 3x/2]xydydx

To evaluate this integral, we first integrate with respect to y and then with respect to x. The inner integral integrates xy with respect to y, giving \((xy^{2/2})\). Then, we integrate the resulting expression \((xy^{2/2})\) with respect to x over the bounds [0,2].

Evaluating this integral, we get:

∬dxyda = ∫[0,2] (x\((6-3x/2)^{2/2}\))dx

Simplifying and evaluating this integral will provide the final result.

The correct statement of function is the function is continuous.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

As, functions approach the same value as x approaches 0.

Now, -x² +4x +1 at x= 2 we get

= -4 + 8 +1 = 5

and, 1/2x + 3 = 1+3= 4

So, we reject the statement.

Now, as x increases without bound,

1/2x +3 increases with bound.

The regular price of a ticket to the baseball game was $18.50.

Mason bought 16 tickets to a baseball game and saved $5.75 per ticket with the group rate. He paid a total of $296.00 for the tickets. To find the regular price of a ticket, we can divide the total cost by the number of tickets:
$296.00 ÷ 16 = $18.50.
Therefore, the regular price of a ticket to the game was $18.50.
To explain further, let's consider the group rate savings. The group rate saved Mason $5.75 per ticket.

This means that if he had paid the regular price,

each ticket would have cost $18.50 + $5.75

= $24.25.

But with the group rate discount, he paid only $18.50 per ticket.
In conclusion, the regular price of a ticket to the baseball game was $18.50.

To find the probability of passing the true/false examination when the number of questions is n, we need to use binomial distribution. We need to plug in the values and calculate the probability of passing for a specific number of questions n

Let X be the number of correct answers the student gets. Since the probability of getting a correct answer is 0.50, we have X ~ Bin(n, 0.50).

To pass the exam, the student must answer at least 70% of the questions correctly. This means that X must be greater than or equal to 0.70n. We can write this as:

P(X >= 0.70n) = 1 - P(X < 0.70n)

Using the binomial distribution formula, we can find the probability of getting less than 0.70n correct answers:

P(X < 0.70n) = ∑(i=0 to 0.70n-1) (n choose i) * 0.50^i * 0.50^(n-i)

We can use a calculator or software to evaluate this sum. For example, if n = 50, we get:

P(X < 0.70n) = P(X < 35) = 0.0738

Therefore, the probability of passing the exam when the number of questions is 50 is:

P(X >= 0.70n) = 1 - P(X < 0.70n) = 1 - 0.0738 = 0.9262

So, the student has a 92.62% chance of passing the exam if there are 50 true/false questions and he answers them by tossing a coin.

To find the probability of passing the true/false examination with a 70% correct answer requirement, we will use the binomial probability formula. The binomial probability formula is:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

Where:
- P(X = k) is the probability of getting k correct answers out of n questions
- C(n, k) is the number of combinations of n items taken k at a time
- p is the probability of getting a correct answer (0.50 in this case)
- n is the number of questions
- k is the number of correct answers

Since we need to find the probability of passing when the number of questions is not specified, let's assume there are n questions. To pass the exam, the student must answer at least 70% of the questions correctly. Therefore, k must be greater than or equal to 0.7n.

The probability of passing the exam can be calculated by summing up the probabilities of getting at least 70% correct answers:

P(passing) = sum(P(X = k)) for k = ceil(0.7n) to n

Where ceil() is the ceiling function that rounds up to the nearest integer.

Now we need to plug in the values and calculate the probability of passing for a specific number of questions n. Please provide the number of questions on the examination to get the exact probability of passing.

The goals does the team score in total in the first 9 matches of the competition is 36 and  their mean number of goals after 10 matches is 3.9.  

Given that the mean number of goals a netball team scores per match in the first 9 matches of a competition is 4.

Thus the average of the goals in 9 matches is 4.

Total number of goals is = 9*4 = 36 goals .

Given that the team scores 3 goals in their next match .

Thus the total number of goals scored in 10 matches is 36 + 3 = 39 goals,

Required mean = Total goals / 10 matches .

∴ Required mean = 39/10 = 3.9 .

Therefore, the goals does the team score in total in the first 9 matches of the competition is 36 and  their mean number of goals after 10 matches is 3.9.

This means that if the average weight of the men in the elevator is more than 180 lbs, the elevator would be overloaded.

To determine the average weight beyond which the elevator would be considered overloaded, we can follow these steps:
Find the total weight limit for 33 occupants: 5940 lbs.

Divide the total weight limit by the number of occupants to find the average weight per person: 5940 / 33 = 180 lbs.
Now, we need to find the difference between the average weight per person (180 lbs) and the mean weight of the population (166 lbs): 180 - 166 = 14 lbs.
Since we have the difference and the standard deviation (26 lbs), we can now calculate the Z-score:

Z = (difference) / (standard deviation) = 14 / 26 ≈ 0.54.
The average weight beyond which the elevator would be considered overloaded is 180 lbs.

The corresponding Z-score for this weight is approximately 0.54.

Answer:

m = 1/2

Step-by-step explanation:

Use two points on the line given.

(0 , 2) & (-4 , 0)

You are solving for the slope. The slope formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-4 , 0)

(x₂ , y₂) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = (2 - 0)/(0 - (-4))

Simplify:

m = (2)/( 0 - (-4))

m = (2)/(0 + 4)

m = 2/4

Simplify the slope. Divide the common factor 2 from both the numerator and denominator:

m = (2/4)/(2/2) = 1/2

1/2 is your slope.

The system of linear equations represented in the graph has one solution.

Linear equations are equations that involve a single variable and can be written in the form ax + b = 0, where a and b are constants, and x is a variable. Linear equations are often used to describe physical processes and are used to solve many real-world problems. They can be used to solve for velocity, distance, time, force, and more.

The line that passes through the points (0,2) and (2,1) is a linear equation, which means that any two points on the line will define a single, unique line. Therefore, the only solution to the equation is the point of intersection of the two points, (1,1.5). This point is the only solution to the system of linear equations represented in the graph.

It is important to note that the linear equation in the graph is not a two-variable equation, but rather a one-variable equation. A two-variable equation would have two lines, which would result in two solutions. However, because only one line is present in the graph, the system of linear equations represented has one solution only.

The length vector is 1. So the sketch vector field f is given below. So the option a is correct.

In the given question, the vector field F by drawing a diagram like this figure.

The given vector field F is:

F(x, y) = (yi + xj)/√(x^2 + y^2)

We can write the vector field as:

F(x, y) = yi/√(x^2 + y^2) + xj/√(x^2 + y^2)

Here

F(x, y) = [y/√(x^2 + y^2)]^2 + [x/√(x^2 + y^2)]^2

F(x, y) = y^2/(x^2 + y^2) + x^2/(x^2 + y^2)

F(x, y) = (y^2+ x^2)/(x^2 + y^2)

F(x, y) = 1

F(0, y) = y/|y| = ±1

F(x, 0) = x/|x| = ±1

Answer:

25,600 and  33,113

Step-by-step explanation:

The computation of the number of students studied abroad in each country is shown below:

Let us assume second most popular host country be x

And the most popular be x + 7513

And, the total students is 58713

Now the equations are

x + x + 7513 = 58713

2x = 58713 - 7513

2x = 51,200

x = 25,600

So the number of students studied abroad is

= 25,600 + 7513

Answer:

The intercept of the line perpendicular to the line \(y = x + 1\) is 5.

Step-by-step explanation:

The line \(y = x + 1\) has a slope 1. By Analytic Geometry, the slope of the line perpendicular to the original line is determine by the following formula:

\(m_{\perp} = -\frac{1}{m}\) (1)

Where:

\(m\) - Slope of the original line.

\(m_{\perp}\) - Slope of the line perpendicular to the original line.

If we know that \(m = 1\), then the new slope is:

\(m_{\perp} = -\frac{1}{1}\)

\(m_{\perp} = -1\)

A line is defined by the following expression:

\(y = m\cdot x + b\) (2)

Where:

\(x\) - Independent variable.

\(y\) - Dependent variable.

\(m\) - Slope.

\(b\) - Intercept.

If we know that \((x,y) = (4,1)\) and \(m = -1\), then the intercept of the line perpendicular to the original line:

\(b = y - m\cdot x\)

\(b = 1+4\)

\(b = 5\)

The intercept of the line perpendicular to the line \(y = x + 1\) is 5.

Answer:To evaluate the exponential expression 6(4+2)² - 32, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, we simplify the expression inside the parentheses:

4 + 2 = 6

Next, we square the result:

6² = 36

Now, we substitute the squared result back into the expression:

6(36) - 32

Next, we perform the multiplication:

6 * 36 = 216

Finally, we subtract 32:

216 - 32 = 184

Therefore, the value of the given exponential expression 6(4+2)² - 32 is 184.
