The rate of change of stock XYZ for this particular week is 13.2%, which is option A.

We need to find the percentage change from the opening price to the closing price.

The percentage change is calculated as follows:

Percentage change = ((closing price - opening price) / opening price) x 100%

Plugging in the given values, we get:

Percentage change = (($10.12 - $8.94) / $8.94) x 100%

Percentage change = ($1.18 / $8.94) x 100%

Percentage change = 0.132 x 100%

Percentage change = 13.2%

Therefore, the rate of change of stock XYZ for this particular week is 13.2%, which is option A.

Answer:

Step-by-step explanation:

If the roots of p(x) are a, b, c, then it factors as ...

  p(x) = (x -a)(x -b)(x -c)

and the expanded form is ...

  p(x) = x^3 -(a+b+c)x^2 +(ac +b(a+c))x -abc

The requirement that the coefficients match the roots means we have three equations in three unknowns:

  a = -(a+b+c)

  b = ac +b(a+c)

  c = -abc

The attachment shows the solutions to these equations. The solutions are found by making the substitutions ...

This leaves us with two equations in two unknowns that can be graphed on a Cartesian plane. The graph of the second equation is a circle:

  x(1 -a -y) -ay = 0   ⇒   (x +1)^2 +y^2 = 1

The graph of the first equation is the union of the line y=0 and two hyperbolas. The points of intersection between this graph and the circle are ...

  (x, y) = (-2, 0), (-1, -1), (0, 0)   ⇒   (a, b, c) = (1, -2, 0), (1, -1, -1), (0, 0, 0)

The three polynomials that correspond to these values are shown above and in the attachment.

There is an irrational fourth solution to the requirement that the roots match the coefficients.

The main advantage of an independent measures design is that it reduces the risk of order or practice effects and minimizes the influence of individual differences between participant

An independent measures design, also known as a between-subjects design, is a type of research study in which different groups of participants are used for each condition being tested.

In other words, each participant is only exposed to one condition, and the data from each group is analyzed and compared to determine if there are any significant differences between the groups.

Answer:

x=9

Step-by-step explanation:

A rhombus is a quadrilateral in which all side lengths are the same. Therefore, the lengths of QR and RS are equivalent, and by extension, the expressions 6x-5 and 4x+13 are equivalent.

Set the two expressions as equivalent to each other, then solve.

6x-5=4x+13

6x=4x+18

The probability that 40 randomly selected buckets will provide enough coating to cover the tank is 0.5000 or 0.5000 (approx) or 0.5000

Given: The surface area of the tank is 80,000 square feet. The coating comes in five-gallon buckets. The area that the coating in one randomly selected bucket can cover varies, with a mean of 2000 square feet and a standard deviation of 100 square feet.

The probability that 40 randomly selected buckets will provide enough coating to cover the tank. (If it matters, you may assume that the selection of any given bucket is independent of the selection of any and all other buckets.)

The area covered by one bucket follows a normal distribution, with a mean of 2000 and a standard deviation of 100. So, the area covered by 40 buckets will follow a normal distribution with a mean μ = 2000 × 40 = 80,000 and a standard deviation σ = √(40 × 100) = 200.

The probability of the coating provided by 40 randomly selected buckets will be enough to cover the tank: P(Area covered by 40 buckets ≥ 80,000).

Z = (80,000 - 80,000) / 200 = 0.

P(Z > 0) = 0.5000 (using the standard normal table).

Therefore, the probability that 40 randomly selected buckets will provide enough coating to cover the tank is 0.5000 or 0.5000 (approx) or 0.5000 (rounded to four decimal places).

Step-by-step explanation:

Consider this question using algebra.

Let the number of candy bars eaten = \(x\)

We are told that Gilbert ate four more than three times the amount of candy bars he ate (pizza). This means that he ate three times the amount of candy bars, plus an extra four slices.

We can use these to form an expression, using our knowledge of \(x\) being the number of candy bars eaten and 10 being the number of pizza slices he ate:

\(3x+4=10\)

Now, we solve for \(x\) to find the number of candy bars he ate:

\(3x+4=10\\3x=6\\x=2\)

Therefore, he ate 2 candy bars.

a. The composition is given by: (f o g)(x) = 3/(x+3). b. The domain of (f o g)(x) is  (-∞, -3) U (-3, 0) U (0, +∞).

To find the composition (f o g)(x), we first need to find g(x) and then substitute it into f(x) wherever we see x. So, we have: g(x) = 3/x

Now, we substitute g(x) into f(x):

(f o g)(x) = f(g(x)) = f(3/x) = (3/x) / [(3/x) + 1] = 3/(x+3)

To find the domain of (f o g)(x), we need to determine the values of x for which (f o g)(x) is defined. We see that (f o g)(x) is defined as long as the denominator of (f o g)(x) is not equal to zero.

Thus, we set the denominator to zero and solve for x:

(x+3) ≠ 0

x ≠ -3

This means that (f o g)(x) is defined for all real numbers except -3. However, we also need to make sure that g(x) is defined for all x in the domain of (f o g)(x).

Since g(x) is not defined at x=0, we need to exclude that value from the domain as well. Therefore, the domain of (f o g)(x) is (-∞, -3) U (-3, 0) U (0, +∞).

The test statistic for randomly interviewed a class of 16 students is given by 1.5.

The population mean is given by = µ = 2

The mean of the sample of class of 16 students is given by = 2.3

Length of size of sample is given by = (n) = 16

Standard deviation is given by = (s) = 0.8

So the test statistic for the test with randomly interviewed a class of 16 students is given by

= (mean of sample - µ)/(s/√n)

= (2.3 - 2)/(0.8/√16)

= 0.3/(0.8/4)

focus on N and move on anti clockwise.

when N moves on anti clockwise about center from original to position A is 120°.

similarly, to X is 180°, to E is 240° and to H is 300°.

To write the system in the form ddt[xy]=p(t)[xy] f⃗ (t), we need to express the derivatives x′ and y′ in terms of xy. We can do this by multiplying the first equation by 8sin(t) and the second equation by 8x - 3cos(t):
8sin(t)x′ = 8sin(t)e^(3t)x - 72sin(t)ty
(8x - 3cos(t))y′ = 8tan(t)(8x - 3cos(t))y

Now we can add these two equations and simplify:
8sin(t)x′ + (8x - 3cos(t))y′ = 8sin(t)e^(3t)x - 72sin(t)ty + 8tan(t)(8x - 3cos(t))y
ddt[xy] = (8sin(t)e^(3t) - 72sin(t)t + 8tan(t)(8x - 3cos(t)))xy
So the system in the desired form is ddt[xy] = (8sin(t)e^(3t) - 72sin(t)t + 8tan(t)(8x - 3cos(t)))xy f⃗ (t).

The total area of the composite figure is approximately 120.99982329 square meters.

In a right triangle, the hypotenuse (the side across from the right angle) has a square length that is equal to the sum of the squares of the lengths of the other two sides. This is known as the Pythagorean theorem.

To find the side of the triangle with hypotenuse 10 and base 6 m, we can use the Pythagorean theorem.

x² + 6² = 10²

x² = 100 - 36

x² = 64

x = 8

The area of the triangle is given as:

Area of triangle = (base * height) / 2

Area of triangle = (6 * 8) / 2 = 24 square meters

The area of the rectangle is:

Area of rectangle = length * width = 12 * 8 = 96 square meters

The area of the semicircle can be found as:

Area of semicircle = (π * radius²) / 2

radius = diameter / 2 = 3 / 2 = 1.5 cm or radius = 0.015 meters

Now,

Area of semicircle = (π * 0.015²) / 2 ≈ 0.00017671 square meters

The area of the composite figure is:

Area = (Area of rectangle + Area of triangle) - Area of semicircle

= (96 + 24) - 0.00017671

≈ 120.99982329 square meters

Hence, the final area of the composite figure is approximately 120.99982329 square meters.
