Answer: Let's call the total amount of grass that Austin collected "G" in kilograms. We know that he collected 30 9/10 kilograms, which can be written as a mixed number or an improper fraction:

30 9/10 = 309/10

So, we have:

G = 309/10

We also know that 2/3 of the grass he collected was blue grass. So, let's call the amount of blue grass "B" in kilograms. We can set up an equation based on the information given:

B = (2/3)G

Substituting G = 309/10, we get:

B = (2/3)(309/10)

B = 206/5

B = 41 1/5

Therefore, the total amount of blue grass Austin collected was 41 1/5 kilograms.

The probability that the vehicle Bob chooses is new or is a car is [tex]\frac{31}{37}[/tex]

To determine the probability that the vehicle Bob chooses is new or is a car at Bob's Auto Plaza, follow these steps:

1. Calculate the total number of vehicles:
  15 new cars + 7 used cars + 9 new trucks + 6 used trucks = 37 vehicles

2. Calculate the number of new vehicles:
  15 new cars + 9 new trucks = 24 new vehicles

3. Calculate the number of cars (both new and used):
  15 new cars + 7 used cars = 22 cars

4. Since we have already counted the new cars in both categories, we need to subtract the number of new cars once to avoid double counting:
  24 new vehicles + 22 cars - 15 new cars = 31 vehicles that are either new or cars

5. Finally, calculate the probability:
  Probability = (number of vehicles that are new or cars) / (total number of vehicles)
  [tex]Probability = \frac{31}{37}[/tex]

So, the probability that the vehicle Bob chooses is new or is a car is [tex]\frac{31}{37}[/tex]  .

Answer:

Part A: The equation 6x + 15 = 6(x + 15) is true for all values of x because it distributes the 6 to both terms inside the parentheses and simplifies to the original expression. However, the equation 6x + 15 = x + x + x + x + x + x + 15 is false for all values of x. While it may be true for specific values of x, such as x = 1 or x = 2, it is not true for all values of x because the number of x terms changes depending on the value of x.

Part B: Another equivalent expression for 6x + 15 could be 3(2x + 5), which also simplifies to the original expression. This is because we can factor out a common factor of 3 from both terms and simplify to 3(2x + 5) = 6x + 15.

The volume of Ganymede is approximately 3.48 times the volume of the Moon, based on the given diameters of the two moons and the formula for the volume of a sphere.

The volume of a sphere is the amount of space occupied by the sphere in three-dimensional space. It can be calculated using the formula V = (4/3)πr³, where V is the volume of the sphere, r is the radius of the sphere, and π (pi) is a mathematical constant approximately equal to 3.14159. This formula states that the volume of a sphere is four-thirds of the product of pi and the cube of the sphere's radius.

In the given question,

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere. Since we are given the diameters of the two moons, we can calculate their radii by dividing the diameters by 2. Therefore, the radius of Ganymede is 3,388/2 = 1,694 km, and the radius of the Moon is 1,245/2 = 622.5 km.

Now, we can calculate the volumes of the two moons:

V_Ganymede = (4/3)π(1694)³ ≈ 7.66 x 10^10 km³

V_Moon = (4/3)π(622.5)³ ≈ 2.2 x 10^10 km³

To find how many times larger Ganymede's volume is compared to the Moon's volume, we can divide the volume of Ganymede by the volume of the Moon:

V_Ganymede / V_Moon ≈ (7.66 x 10¹⁰) / (2.2 x 10¹⁰) ≈ 3.48

Therefore, the volume of Ganymede is approximately 3.48 times the volume of the Moon.

Answer:

To perform McNemar's test, we need to find the number of discordant pairs, i.e., the pairs of individuals who change their response from before to after college. In this case, there are 23 students who said "yes" before college but "no" after college, and 11 students who said "no" before college but "yes" after college. Therefore, there are 23 discordant pairs.

The test statistic for McNemar's test is calculated as:

z = (|b-c| - 1) / √(b+c)

where b is the number of discordant pairs who responded "yes" before college, and c is the number of discordant pairs who responded "no" before college.

In this case, b = 23 and c = 11, so:

z = (|23-11| - 1) / √(23+11)

z = 1.96

Therefore, the test statistic is 1.96

The function f has a relative maximum at x = -√[(2 + sqrt(2))/5], so the answer is (b) - root 5/5.

To find the relative maximum of a function, we need to find the critical points of the function, where the derivative of the function is zero or undefined.

Let's start by finding the derivative of f(x)

f'(x) = 15x⁴ - 12x² - 3

Now, we can find the critical points by solving the equation f'(x) = 0

15x⁴ - 12x² - 3 = 0

We can factor this equation by substituting y = x²

15y² - 12y - 3 = 0

Solving for y, we get

y = (2 ± √(2))/5

Substituting back x² for y, we get

x² = (2 ± √(2))/5

Taking the square root of both sides, we get

x = ± √[(2 ± √(2))/5]

Therefore, the critical points are

x = -√[(2 + √(2))/5], √[(2 - √(2))/5]

Now, we need to determine whether these critical points are relative maximum or minimum.

We can use the second derivative test to determine the nature of the critical points. The second derivative of f(x) is

f''(x) = 60x³ - 24x

Plugging in the critical points, we get

f''(-√[(2 + √(2))/5]) = -48√(2) < 0 (relative maximum)

f''(√[(2 - √(2))/5]) = 48√(2) > 0 (relative minimum)

Therefore, the relative maximum of the function f(x) is at

x = -√[(2 + √(2))/5]

So, the correct answer is (b) - root 5/5.

The speed of boat is 5/6 meter per second and height of boat is 50[tex]\sqrt{3}[/tex] meter.

An angle is a shape created by two rays or lines that meet at the same terminal. The Latin word "angulus" (which means "corner") is where the term "angle" first appeared. The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle. It is not necessary for the angle to be in Euclidean space if it lies in the plane. Angles are referred to as dihedral angles if they are created by the intersection of two planes in a space other than Euclidean. The sign "" is used to denote angles. The Greek letter,,, etc. can be used to represent the angle between the two beams.

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

The speed of the boat from point C to point B is approximately 10.82 meters per second.

What is speed ?

Speed is a measure of how fast an object is moving. It is the rate at which an object covers distance.

We can use trigonometry to solve for h and the speed of the boat. Let's start with h:

From the right triangle CLB, we have:

tan 30° = h / CB

where CB is the distance between points C and B, which is given as 50 meters. Solving for h, we get:

h = CB * tan 30° = 50 * tan 30° ≈ 28.87 meters

So the height of the lighthouse is approximately 28.87 meters.

Now let's find the speed of the boat. We know that the boat travels from point C to point B in 1 minute, which is equivalent to 60 seconds. Let's define the speed of the boat as v, in meters per second. Then we have:

v = CB / t

where t is the time it takes for the boat to travel from point C to point B. We can find t using the distance formula:

[tex]CB = \sqrt{(x_B - x_C)^2 + (y_B - y_C)^2[/tex]

where x and y are the coordinates of each point. From the diagram, we can see that:

[tex]x_C = 0[/tex]

[tex]y_C = 0[/tex]

[tex]x_B = BL * cos \theta[/tex]

[tex]y_B = BL * sin \theta[/tex]

where BL is the distance from point B to the foot of the lighthouse, which is equal to h / tan θ. Therefore:

CB [tex]= \sqrt{((BL * cos \theta)^2 + (BL * sin \theta)^2)[/tex]

     [tex]= \sqrt{(BL^2 * (cos^2 \theta + sin^2 \theta))[/tex]

     [tex]= BL = h / tan \theta[/tex]

Substituting the values we have found, we get:

v = CB / t = (h / tan θ) / 60 ≈ 10.82 meters per second

Therefore, the speed of the boat from point C to point B is approximately 10.82 meters per second.

The probability of exactly 17 successes in a binomial distribution with p=0.20 and n=60, using normal approximation to the binomial, is approximately 0.0129.

To use the normal approximation to the binomial, we need to check if the conditions for the approximation are met

np = 60 x 0.20 = 12 ≥ 10

n(1-p) = 60 x 0.80 = 48 ≥ 10

Both conditions are met, so we can use the normal approximation to the binomial.

The mean of the binomial distribution is μ = np = 12, and the standard deviation is σ = √(np(1-p)) = √(60 x 0.20 x 0.80) ≈ 2.19.

To find the probability of exactly 17 successes, we can use the normal distribution with mean μ = 12 and standard deviation σ ≈ 2.19, and approximate the discrete binomial distribution with a continuous normal distribution

P(X = 17) ≈ P(16.5 < X < 17.5)

where X is a continuous random variable that follows a normal distribution with mean μ = 12 and standard deviation σ ≈ 2.19.

Using the standard normal distribution, we can calculate the z-scores for 16.5 and 17.5

z1 = (16.5 - 12) / 2.19 ≈ 1.83

z2 = (17.5 - 12) / 2.19 ≈ 2.28

Using a standard normal distribution table or a calculator, we can find the probabilities associated with these z-scores

P(1.83 < Z < 2.28) ≈ P(Z < 2.28) - P(Z < 1.83) ≈ 0.0129

By applying Pythagoras' theorem in this right-angled triangle formed in our image, we obtain the given formula

[tex]H^2 = P^2 + B^2[/tex]

[tex](r + s)^2 = (r - s)^2 + (r - 3s)^2[/tex]

[tex]r^2 + 2r.s + s^2 = 2r^2 - 8r.s + 10.s^2[/tex]

[tex]r^2 - 10.r.s + 9s^2 = 0[/tex]

(r - 9s) (r - s) = 0
