The radius of a quarter circle is 2 yards. What is the quarter circle's perimeter?

A graph of each function is shown in the image attached below.

The number of commercials (x) is equal to 7 commercials while the number of movies (y) is equal to 2 movies.

In order to graphically solve the system of equations, we would write two (2) equations that models the situation by assigning variables to the number of commercials and number of movies respectively, and then translate the word problem into algebraic equation as follows:

Since Victoria would earn $40 every time one of her songs is played in a commercial and $140 every time one of her songs is played in a movie, an equation which models it is;

40x + 140y = 560

Additionally, Victoria earned a total of $560 in royalties on 9 commercials and movies;

x + y = 9

Next, we would use an online graphing calculator to plot the above system of equations with a point of intersection at (7, 2) as shown in the image attached below.

The approximate number of packets containing blades with no defective is :  9802

We are given the probability of defect per blade = 1/500 = 0.002

The general formula for Poisson distribution is;

Pₓ (k) = (x^k)/k × e⁻ˣ

Where;

k = The number of defective blades in a packet.

For a packet of 10 blades the mean number of defect is;

x = 0.002 × 10

x = 0.02

When there is no defective in a consignment, then it means k = 0

Thus;

Pₓ(0) = (0.02⁰ / 0!) × e^(-0.02) = 0.980199

Answer:

y = 1/3x

Step-by-step explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

The slope = rise/run

Let's pick 2 points (0,0) (3,1), we see the y increase by 1 and the x increase by 3, so the slope is

m = 1/3

The y-intercept is located at (0,0)

So, our equation is

y = 1/3x

The equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.

Here,

To find the equation of the line passing through the points (0, 3) and (-5, 0), we can use the slope-intercept form and the slope formula:

m = (y2 - y1) / (x2 - x1) = (0 - 3) / (-5 - 0) = -3/5

where (x1, y1) = (0, 3) and (x2, y2) = (-5, 0) are the coordinates of the given points.

Now we can substitute the value of m and the coordinates of one of the points into the equation of the line to find the value of b:

y = mx + b

3 = (-3/5)*0 + b

b = 3

So the equation of the line passing through the points (0, 3) and (-5, 0) is:

y = -3/5 x + 3

We can also convert the equation to point-slope form as :

y - y1 = m(x - x1)

y - 3 = (-3/5)(x - 0)

y - 3 = -3/5 x

y = -3/5 x + 3

Hence, the equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3

The length of the midsegment of 28. is 17 units and 29. is 27 units.

A line drawn by joining the midpoints of any two of the triangle's sides is known as the midsegment. All three sides of a triangle can be divided in half, with the midpoint being the point that is equally spaced from either vertex, regardless of whether the triangle is a right triangle, isosceles triangle, or sometimes an equilateral triangle.

If the slope and sides are same then we can cut the midsegment ad paste it such that it becomes an rectangle.

28. Now the length of the rectangle = n + 12 + n + 12 = 4n + 6 + 2n - 2

⇒ 2n + 24 = 6n +4

⇒ 20 = 4n

⇒ n = 20/4

⇒ n = 5

Length of midsegment = 5 + 12

                                       =  17 units

29. Now the length of the rectangle = 2n+ 11 + 2n+ 11 = 5n - 2 + n + 8

⇒ 4n + 22 = 6n + 6

⇒ 16  = 2n

⇒ n = 16/2

⇒ n = 8

Length of midsegment = 2(8) + 11

= 0.5

Favourable outcomes for event B = 6 = { (1,1),(2,2),(3,3),(4,4), (4,1) (4,2) (4,3), (5,5),(6,6)}

ii) So, Probability that first roll is equal to the second, P(B) = 6/36 = 0.166

Favourable outcomes for event C = 15 = { (2,1),(3,2),(3,1),(4,1),(5,1) (5,2) (5,3) (5,4),(6,1) (6,2) (6,3) (6,4) (6,5) (6,4), (6,5)}

Doing moves to keep an equation balanced is a powerful part of solving equations, but thinking about what the structure of an equation tells us about the solutions is just as iimportant

Sometimes it’s possible to look at the structure of an equation and tell if it has infinitely many solutions or no solutions. For example, look at

2(12x + 18) + 6 = 18x + 6(x + 7)

Using the distributive property on the left and right sides, we get

24x + 36 + 6 = 18x + 6x + 42

From here, collecting like terms gives us

24x + 42 = 24x + 42

Since the left and right sides of the equation are the same, we know that this equation is true for any value of x without doing any more moves!

Similarly, we can sometimes use structure to tell if an equation has no solutions. For example, look at

6(6x + 5) = 12(3x + 2) + 12

If we think about each move as we go, we can stop when we realize there is no solution

1/6 · 6(6x + 5) = 1/6 · (12(3x + 2) + 12) Multiply each side by 1/6

6x + 5 = 2(3x + 2) + 2 Distribute 1/6 on the right side.

6x + 5 = 6x + 4 + 2 Distribute 2 on the right side.

The last move makes it clear that the constant terms on each side, 5 and 4 + 2, are not the same. Since adding 5 to an amount is always less than adding 4 + 2 to that same amount, we know there are no solutions.

The matrix is given as

2 1 -1

3 2 -3

3 1 -2

To find the eigenvalues and eigenvectors of a matrix A, we need to solve the following equation:

Av = λv

where v is the eigenvector and λ is the eigenvalue.

So, we have

(2 1 -1) (x) = λ (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

We can find the eigenvalues by solving the characteristic equation which is det(A-λI) = 0.

The characteristic equation for the above matrix is

(2-λ)((-λ-2)(-λ+1) - 2) - 3(1)(-λ+1) + 3(1)(-λ-2) = 0

Solving the above equation we get λ = -1,1,3

Now we can find the eigenvectors for each eigenvalue.

For λ = -1

(2 1 -1) (x) = -1 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = -1, y = 2 and z = 2. So the eigenvector is [-1,2,2].

For λ = 1

(2 1 -1) (x) = 1 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = 1, y = -1 and z = -1. So the eigenvector is [1,-1,-1].

For λ = 3

(2 1 -1) (x) = 3 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = 1, y = 1 and z = 1. So the eigenvector is [1,1,1].

To add 2 1/2 + 4/5 using a number line, we can start by marking off the whole numbers along the number line. Then, we can divide each whole number into equal parts to represent the fractions. For example, if we divide each whole number into fifths, we can mark off 2 1/5, 2 2/5, 2 3/5, etc.

After the above, the next thing is that we can find the point on the number line that represents 2 1/2 by starting at 2 and moving 1/5 of the way to the right. Similarly, we can find the point that represents 4/5 by starting at 4 and moving 1/5 of the way to the right.

Finally, to add the two numbers, we can simply move from the point that represents 2 1/2 to the point that represents 4/5. The final point we reach will be the sum of 2 1/2 + 4/5. In this example, the final point will be 3 3/10.

Therefore, 2 1/2 + 4/5 will be 3 3/10.

The numeric values of each function at x = 3 are given as follows:

f(3) = 50.

g(3) = 10.

The division is given as follows: f(3)/g(3) = 5.

The space of f(x)/g(x) is given as all genuine values with the exception of x = - 7, as the function g(x), which is the denominator of the division, expects a worth of 0 at x = - 7.

To track down the numeric worth of a function or of articulation, we supplant each example of the variable in the function or in the articulation with the worth at which we need to track down the numeric worth.

Subsequently, the numeric values are found to supplant the solitary example of x by 3 in each function, as follows:

f(3) = 5(3) + 35 = 15 + 35 = 50.

g(3) = 3 + 7 = 10.

Subsequently, the division is given as follows:

(f/g)(3) = f(3)/g(3) = 50/10 = 5.

The value of -0.6675 for the correlation coefficient of X and Y indicates that there is a negative correlation between the two variables.

The correlation coefficient, denoted as p, is a measure of the linear relationship between two random variables X and Y. It is defined as the ratio of the covariance of X and Y to the product of their standard deviations:

p = cov(X,Y) / (stdDev(X) × stdDev(Y))

To compute the correlation coefficient, we need to first calculate the covariance and the standard deviations of X and Y.

Since the marginals pdfs of X and Y are the same, we know that the expected value (mean) of X is equal to the expected value of Y, which is denoted as Mu x = Mu y = A.

The expected value of XY is given as E(XY) = 2/5.

The covariance of X and Y is defined as E((X-Mu x )(Y-Mu y )), which simplifies to E(XY) - Mu x × Mu y

Substituting the given values, we have:

cov(X,Y) = E(XY) - Mu x × Mu y = 2/5 - A²

To calculate the standard deviation of X and Y, we need to calculate the variance first. The variance of X is defined as E(X²) - (Mu x )²,

which can be easily calculated by replacing x with y in fx(x) and applying the same formula.

The standard deviation is the square root of the variance, so we have:

stdDev(X) = √(variance(X)) = √(E(X²) - (Mu x )²)

stdDev(Y) = √(variance(Y)) = √(E(Y²) - (Mu y )²) = √(E(X²) - (Mu x )²)

Now we can substitute these values into the formula for p:

p = cov(X,Y) / (stdDev(X) × stdDev(Y)) = (2/5 - A²) / (√(E(X²) - (Mu x )²) × √(E(X²) - (Mu x )²)).
