Answer:

107 pages.

Step-by-step explanation:

100 - 47 - 28 = 25% are on Physics.

Number of pages on physics = 0.25 * 428

= 107.

Answer:

There are 107 pages devoted to physics.

Step-by-step explanation:

The number of pages on bio is 0.47(428) = 201 (rounded up from 201.16);

the number of pages for on chem is 0.28(428) = 120 (rounded up from 119.84), and so the total number of pages devoted to bio and chem is

201 + 120, or 321.

Subtracting this subtotal from the book's 428 pages yields 107.

There are 107 pages devoted to physics.

The probability that Aaron selects a terrier, given Rebecka selects a poodle, is 1/3.

To find the probability that Aaron selects a terrier, given Rebecka selects a poodle, we need to use conditional probability.

First, we need to find the probability that Rebecka selects a poodle. Since there are four poodles out of seven puppies total, the probability that Rebecka selects a poodle is 4/7.

Next, we need to find the probability that Aaron selects a terrier, given that Rebecka has already selected a poodle. Now there are only three poodles and two terriers left in the store, so the probability that Aaron selects a terrier is 2/6 (or simplified, 1/3).

Putting it all together, we can use the formula for conditional probability:

P(Aaron selects a terrier | Rebecka selects a poodle) = P(Aaron selects a terrier and Rebecka selects a poodle) / P(Rebecka selects a poodle)

Since we know that Rebecka selects a poodle, the numerator is just the probability that Aaron selects a terrier given that there are three puppies left in the store. So:

P(Aaron selects a terrier and Rebecka selects a poodle) = (1/3) * (4/7) = 4/21

And we already calculated that P(Rebecka selects a poodle) = 4/7. So:

P(Aaron selects a terrier | Rebecka selects a poodle) = (4/21) / (4/7) = 1/3

Therefore, the probability that Aaron selects a terrier, given Rebecka selects a poodle, is 1/3.

Answer:

\(x=-2\)

Step-by-step explanation:

Lets solve for x.

\(7x-12=4(x-9)-9x\)

Apply the distributive property in \(4(x-9)\).

\(7x-12=4x-36-9x\)

Subtract \(9x\) from \(4x\).

\(7x-12=-5x-36\)

Subtract \(7x\) from both sides of the equation.

\(-12=-5x-36-7x\)

Subtract \(7x\) from \(-5x\).

\(-12=-12x-36\)

Add 36 to both sides of the equation.

\(24=-12x\)

\(-12x=24\)

Divide both sides of the equation by -12.

The major branch of statistics that deals with making inferences about a population based on a sample is called inferential statistics.

In this scenario, you collected data from a sample of eight classmates and calculated the average score to be 65.

Based on this sample, you made an inference about the entire class, stating that the average test score for the whole class was less than 70. This inference is an example of using inferential statistics. Inferential statistics allows us to draw conclusions and make predictions about a larger population based on a smaller sample.

By using statistical techniques and assumptions, we can estimate parameters, such as the population mean, using sample statistics. This helps us make informed decisions and generalizations about a population when it is not feasible or practical to collect data from the entire population.

Therefore, the measure of the central angle whose radii define the given arc is approximately 83.077 degrees.

The length of an arc on a circle is given by the formula:

Arc Length = (Central Angle / 360°) * Circumference

In this case, we know the arc length is 6π centimeters, and the radius of the circle is 13 centimeters. The circumference of the circle can be calculated using the formula:

Circumference = 2π * Radius

Substituting the radius value, we get:

Circumference = 2π * 13

= 26π

Now we can use the arc length formula to find the central angle:

6π = (Central Angle / 360°) * 26π

Dividing both sides of the equation by 26π:

6π / 26π = Central Angle / 360°

Simplifying:

6 / 26 = Central Angle / 360°

Cross-multiplying:

360° * 6 = 26 * Central Angle

2160° = 26 * Central Angle

Dividing both sides by 26:

2160° / 26 = Central Angle

Step-by-step explanation:

If rp is 0.27ra, then a moon's orbital eccentricity is 0.57. Thus, option (a) is the correct answer.

Though the moon does not move around andra in a perfect ellipse, here, we assume that the moon's orbit is in the shape of an ellipse, we know that:

\(e = \frac{ra - rp}{ra + rp}\) ... (i)

where e ⇒ eccentricity of the ellipse

ra ⇒ apoapsis i.e., the longest distance between the moon and its planet

rp ⇒ periapsis i.e., the shortest distance between the moon and its planet

From the question, we know

rp = 0.27 ra

Putting this value in equation (i) we get:

\(e = \frac{ra-0.27ra}{ra+0.27ra}\\\)

\(e=\frac{0.73ra}{1.27ra}\)

e = 0.57

Hence, if rp is 0.27 of ra, the moon's orbital eccentricity is 0.57.

Let's break down the expression for Tony's combined total earnings step by step.

First, we consider Tony's earnings as a tutor. He earns $11 per hour as a tutor, so the amount he earns from tutoring is given by the product of his hourly rate ($11) and the number of hours he worked as a tutor (t). This can be represented as $11t.

Next, we consider Tony's earnings as a waiter. He earns $13 per hour as a waiter, so the amount he earns from waiting tables is given by the product of his hourly rate ($13) and the number of hours he worked as a waiter. Since Tony worked a total of 106 hours this month and spent t hours as a tutor, he must have worked (106 - t) hours as a waiter. This can be represented as $13(106 - t).

To calculate Tony's combined total earnings for the month, we add the amount he earned as a tutor ($11t) to the amount he earned as a waiter ($13(106 - t)). This yields the expression:

Earnings = $11t + $13(106 - t)

This expression represents the total dollar amount Tony earned this month, considering the number of hours he worked as a tutor (t) and waiter (106 - t).

For incompressible flow in a horizontal pipe of constant diameter and without fittings or valves, the pressure is a linear function of pipe length.

Linear function:A linear function can be defined as a function that shows a constant rate of change between input values (x) and output values (y). When we plot the graph of a linear function, it shows a straight line. The standard form of a linear function is y = mx + b, where m is the slope and b is the y-intercept.

Pressure:Pressure is defined as the force exerted per unit area. Pressure is a scalar quantity. It can be measured in units such as pascals, bars, pounds per square inch, etc.

Now let's consider the given statement for incompressible flow in a horizontal pipe of constant diameter and without fittings or valves to prove that pressure is a linear function of pipe length.

In a horizontal pipe of constant diameter, the following assumptions are made:No valves and fittings are presentFluid is incompressibleFriction is negligibleThe fluid flow is steady-state and laminarAt two points P1 and P2 along the horizontal pipe, let us assume that the fluid pressure and velocity are P1, V1 and P2, V2, respectively.

The pressure drop between the two points is given byΔP = P1 - P2The flow rate of the fluid through the pipe is given by the equation,Q = (A1V1) = (A2V2)

where, A is the cross-sectional area of the pipe.

Substituting V1 = Q/A1 and V2 = Q/A2 in ΔP = P1 - P2, we getΔP = P1 - P2 = 32μQL / πd4,

where μ is the viscosity of the fluid, L is the length of the pipe, d is the diameter of the pipe.

The above equation is called the Hagen-Poiseuille equation. It shows that pressure drop (ΔP) is proportional to the length of the pipe (L) when the other parameters such as flow rate (Q), viscosity (μ), and diameter (d) of the pipe are constant.

Thus, it can be concluded that the pressure is a linear function of pipe length.

We are given the function f(x) = x^2 - 87x - 4 and need to determine the intervals of increasing and decreasing, find the local maximum and minimum values, identify the intervals of concavity, and determine the inflection points.

To find the intervals of increasing and decreasing, we need to examine the first derivative of the function. Taking the derivative of f(x) gives f'(x) = 2x - 87. Setting f'(x) = 0, we find x = 43.5, which divides the real number line into two intervals. For x < 43.5, f'(x) < 0, indicating that f(x) is decreasing, and for x > 43.5, f'(x) > 0, indicating that f(x) is increasing. To find the local maximum and minimum values, we can analyze the critical points. In this case, the critical point is x = 43.5. By plugging this value into the original function, we can find the corresponding y-value, which represents the local minimum. To identify the intervals of concavity and inflection points, we need to examine the second derivative of the function. Taking the derivative of f'(x) = 2x - 87 gives f''(x) = 2, which is a constant. Since the second derivative is always positive, the function is concave up for all values of x.

The coordinates of X that partitions XY in the ratio 5 to 4 include the following: X (-1.6, -7).

In this scenario, line ratio would be used to determine the coordinates of the point X on the directed line segment AB that partitions the segment into a ratio of 5 to 4.

In Mathematics and Geometry, line ratio can be used to determine the coordinates of X and this is modeled by this mathematical equation:

M(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

By substituting the given parameters into the formula for line ratio, we have;

M(x, y) = [(5(2) + 4(-6))/(5 + 4)],  [(5(-11) + 4(-2))/(5 + 4)]

M(x, y) = [(10 - 24)/(9)],  [(-55 - 8)/9]

Step-by-step explanation:

Te plus/minus sign in front of the square root indicates that there are two possible values for \( \cos(2x) \), depending on whether \( \cos(x) \) is positive or negative.

To find the value of \( \cos(2x) \) when given \( \cot(x) = \frac{11}{28} \), we can use trigonometric identities and algebraic methods.

First, let's recall some trigonometric identities that will be helpful in this problem:

1. \( \cot(x) = \frac{1}{\tan(x)} \)

2. \( \cos(2x) = 1 - 2\sin^2(x) \)

3. \( \sin^2(x) + \cos^2(x) = 1 \)

Given that \( \cot(x) = \frac{11}{28} \), we can rewrite it as \( \frac{1}{\tan(x)} = \frac{11}{28} \).

To find \( \tan(x) \), we can take the reciprocal of both sides:

\[ \tan(x) = \frac{28}{11} \]

Next, using the identity \( \sin^2(x) + \cos^2(x) = 1 \), we can find \( \cos^2(x) \):

\[ \cos^2(x) = 1 - \sin^2(x) \]

Since we know \( \tan(x) = \frac{28}{11} \), we can substitute it into the equation above:

\[ \cos^2(x) = 1 - \left(\frac{1}{1 + \tan^2(x)}\right)^2 \]

Simplifying further:

\[ \cos^2(x) = 1 - \left(\frac{1}{1 + \left(\frac{28}{11}\right)^2}\right)^2 \]

Taking the square root of both sides:

\[ \cos(x) = \pm \sqrt{1 - \left(\frac{1}{1 + \left(\frac{28}{11}\right)^2}\right)^2} \]

Finally, to find \( \cos(2x) \), we substitute the value of \( \cos(x) \) into the identity \( \cos(2x) = 1 - 2\sin^2(x) \):

\[ \cos(2x) = 1 - 2\left(\pm \sqrt{1 - \left(\frac{1}{1 + \left(\frac{28}{11}\right)^2}\right)^2}\right)^2 \]

Simplifying and calculating the value using a calculator will give you the accurate answer to four decimal places.
