Answers

Answer 1

The correct answer is option B: "Because the probability of overloading is lower with the new ratings than with the old ratings, the new ratings appear to be safe when the boat is loaded with 16 passengers."

a) Using the given mean and standard deviation, we can standardize the weight of the passengers to find the z-score:

z = (x - μ) / σ

z = (178.2 - 140) / 39.2

z = 0.9719

Using a standard normal distribution table or calculator, we can find the probability of a z-score greater than 0.9719:

P(z > 0.9719) = 1 - P(z <= 0.9719) = 1 - 0.8349 = 0.1651

So the probability that the boat is overloaded because the mean weight of the 70 passengers is greater than 140 lb is 0.1651.

b) The new load limit is 2,736 lb, which means the average weight per passenger should be no more than 2736/16 = 171 lb. We can standardize the weight of the passengers again:

z = (171 - 178.2) / (39.2 / sqrt(16))

z = -2.3155

Using a standard normal distribution table or calculator, we can find the probability of a z-score less than -2.3155:

P(z < -2.3155) = 0.0104

So the probability that the boat is overloaded because the mean weight of the 16 passengers is greater than 171 lb is 0.0104.

Since the probability of overloading is lower with the new ratings than with the old ratings, the new ratings appear to be safe when the boat is loaded with 16 passengers. Therefore, the correct answer is option B: "Because the probability of overloading is lower with the new ratings than with the old ratings, the new ratings appear to be safe when the boat is loaded with 16 passengers."

18,12,8,.

Find the 8th term.

What’s the answer

Answers

The 8th term in the sequence is -24.

To find the 8th term in the sequence 18, 12, 8, we need to first identify the pattern or rule that generates the sequence. From observing the sequence, we can see that each term is obtained by subtracting 6 from the previous term.

So, the sequence can be written as:

18, 12, 6, 0, -6, -12, -18, -24, ...

To find the 8th term, we need to apply the pattern 7 times (since we already have the first term).

Starting with 18, we subtract 6 seven times:

18 - 6 = 12

12 - 6 = 6

6 - 6 = 0

0 - 6 = -6

-6 - 6 = -12

-12 - 6 = -18

-18 - 6 = -24

It's important to note that the pattern we identified only applies to this specific sequence. To find the nth term of a sequence, we need to look for a more general pattern or rule that generates all the terms in the sequence.

Market profit potential is established as the vertical axis in the BCG portfolio analysis to determine how attractive a particular market is.

The BCG (Boston Consulting Group) portfolio analysis is a framework used to analyze a company's business units or product lines based on their market growth rate and relative market share. The relative market share is established as the horizontal axis, and the market growth rate is established as the vertical axis. The resulting four quadrants are named: "Stars," "Cash Cows," "Question Marks," and "Dogs."

However, in some modified versions of the BCG matrix, such as the GE-McKinsey Matrix, the vertical axis may be replaced with other factors such as market attractiveness, industry strength, or competitive position.

It costs $1.12 to buy 7 gift tags. If the tags all cost the same amount, what is the price of each tag?

Answers

We have,

To solve this problem, we need to determine the price of each gift tag given that it costs $1.12 to buy 7 tags.

Let "x" be the price of each gift tag in dollars.

Then, if we buy 7 tags, the total cost would be 7 times the price of each tag:

7x

We know that this total cost is $1.12, so we can set up a proportion:

7x / 1 = 1.12 / 1

Simplifying, we get:

7x = 1.12

Now we can solve for "x" by dividing both sides by 7:

x = 1.12 / 7

80 volunteers take a meningitis test to help doctors see how accurate this test is at identifying whether someone has meningitis or not.
A positive result means the test has identified you as having meningitis.
Of the volunteers, only 8 people have meningitis.
The results show 2 people who have meningitis gets a negative result and 3 people who don't have meningitis get a positive result.
What was the accuracy of the test?

Answers

Out of the 80 volunteers, only 8 people have meningitis. Of these 8 people, 2 people got a negative result. This means that 6 out of 8 people with meningitis got a positive result, which is a sensitivity of 6/8 or 75%.

Out of the 72 volunteers who do not have meningitis, 3 people got a positive result. This means that 69 out of 72 people who do not have meningitis got a negative result, which is a specificity of 69/72 or 95.83%.

The accuracy of the test can be calculated using the formula:

Accuracy = (True Positives + True Negatives) / Total

True Positives = 6 (people with meningitis who got a positive result)
True Negatives = 69 (people without meningitis who got a negative result)
Total = 80 (total number of volunteers)

Accuracy = (6 + 69) / 80 = 0.938 or 93.8%

Therefore, the accuracy of the test is 93.8%.

Find the area and perimeter of rectangle DEFG whose

endpoints are D(-3, 1), E(1, 3), F(2, 1), and G(-2, -1)

Answers

The area of rectangle DEFG is 16 square units and its perimeter is 12 units.

To find the area, we can use the formula: Area = length x width We can find the length and width by calculating the distance between the coordinates of opposite sides of the rectangle.

Length = EF =

[tex] \sqrt{} ((2-1)^2 + (1-3)^2)[/tex]

=

[tex] \sqrt{} (2 + 4) = \sqrt{} (6)[/tex]

Width = DG =

[tex] \sqrt{} ((-3+2)^2 + (1+1)^2) = \sqrt{} (2 + 4) = \sqrt{} (6)[/tex]

The area of rectangle DEFG = length x width =

[tex] \sqrt{} (6) x \sqrt{} (6)[/tex]

= 6 x 2 = 16 square units.

To find the perimeter, we can add up the lengths of all four sides: Perimeter = DE + EF + FG + GD

DE =

[tex] \sqrt{} ((1+3)^2 + (-3+(-1))^2) = \sqrt{} (16 + 4) = \sqrt{} (20)[/tex]

EF =

[tex] \sqrt{} ((2-1)^2 + (1-3)^2) = \sqrt{} (2 + 4) = \sqrt{} (6)[/tex]

What is the probability of obtaining exactly seven heads? b. What is the probability of obtaining exactly ten heads? c. What is the probability of obtaining no heads? d. What is the probability of obtaining at least one head?

Answers

The probability of obtaining exactly seven heads can be calculated using the binomial probability formula: P(X=7) = (10 choose 7) * (0.7)^7 * (0.3)^3 = 0.2668, where (10 choose 7) represents the number of ways to choose 7 heads out of 10 tosses.

The probability of obtaining exactly ten heads is also calculated using the binomial probability formula: P(X=10) = (10 choose 10) * (0.7)^10 * (0.3)^0 = 0.0282, where (10 choose 10) represents the number of ways to choose all 10 heads out of 10 tosses.

The probability of obtaining no heads can be calculated by using the complement rule: P(no heads) = 1 - P(at least one head). Since there are only two outcomes (heads or tails) for each toss, the probability of obtaining no heads is simply (0.3)^10 = 0.000005904.

P(X ≤ 1500) =
P(X> 1500) =
So the probability that the bookstore breaks even in a given month
is____

Answers

π₂ = $45,900, σ₂=  $21.87, P(X> 1500) = 1. The probability that the bookstore breaks even in a given month is practically 1 or 100%.

To solve this problem, first, we need to calculate the mean and standard deviation of the distribution of the monthly sales.

Mean (π) = $1530

Standard deviation (σ) = $120

Number of days in a month = 30

The mean of the distribution of monthly sales is equal to the daily mean multiplied by the number of days in a month:

π₂ = π₁ × n = $1530 × 30 = $45,900

The standard deviation of the distribution of monthly sales is equal to the daily standard deviation divided by the square root of the number of days in a month:

σ₂ = σ₁ / sqrt(n) = $120 / sqrt(30) ≈ $21.87

Now, we can use the z-score formula to convert the daily sales average to a standard normal distribution:

z = (x - π) / σ = ($50 - $1530) / $120 = -12.25

Using a standard normal distribution table, we can find that the probability of z being greater than -12.25 is practically 1.

Therefore, the probability of the bookstore breaking even in a given month is essentially 1 or 100%.

Suppose it costs ​$49 to roll a pair of dice. You get paid 7 dollars times the sum of the numbers that appear on the dice. What is the expected payoff of the​ game? is it a fair​ game?

Answers

Here, the expected payoff of the game is $44.83. Since the cost to play the game is $49, the game is not fair and the player can expect to lose money on average.

Pair of dice is rolled, the possible outcomes and their corresponding sums and payouts are:

Sum 2: payout = 7 * 2 = 14

Sum 3: payout = 7 * 3 = 21

Sum 4: payout = 7 * 4 = 28

Sum 5: payout = 7 * 5 = 35

Sum 6: payout = 7 * 6 = 42

Sum 7: payout = 7 * 7 = 49

Sum 8: payout = 7 * 8 = 56

Sum 9: payout = 7 * 9 = 63

Sum 10: payout = 7 * 10 = 70

Sum 11: payout = 7 * 11 = 77

Sum 12: payout = 7 * 12 = 84

Each sum has a probability of occurring, given by the number of ways that sum can be obtained divided by the total number of possible outcomes. For example, the sum of 2 can only be obtained by rolling a 1 on each die, so it has a probability of 1/36. The sum of 7 can be obtained in six ways (1+6, 2+5, 3+4, 4+3, 5+2, 6+1), so it has a probability of 6/36 = 1/6.

The expected payoff of the game is the sum of the product of each payout and its corresponding probability. We can calculate this as follows:

(14 * 1/36) + (21 * 2/36) + (28 * 3/36) + (35 * 4/36) + (42 * 5/36) + (49 * 6/36) + (56 * 5/36) + (63 * 4/36) + (70 * 3/36) + (77 * 2/36) + (84 * 1/36)

= (14 + 42 + 84 + 140 + 210 + 294 + 280 + 252 + 210 + 154 + 84) / 36

Answers

To prove that when a sphere is moved about its center, it is always possible to find a diameter of the sphere whose direction in the displaced position is the same as in the initial position using orthogonal properties, follow these steps:

1. Consider a sphere with center O and any diameter AB.
2. When the sphere is moved about its center, the center O remains fixed.
3. Rotate the sphere such that diameter AB is now in a new position A'B'.
4. Since the sphere has been rotated about its center, the orthogonal properties are preserved. This means that the planes that are perpendicular to the diameter at the center O remain unchanged.
5. The orthogonal planes to diameter AB intersect at the center O and form a fixed line in space.
6. Now, rotate the sphere again, such that diameter A'B' returns to its initial position as AB. This rotation is possible because the orthogonal planes and their intersection (the fixed line) are preserved.
7. Since diameter A'B' has returned to the initial position of AB, it proves that it is always possible to find a diameter of the sphere whose direction in the displaced position is the same as in the initial position.

The most general solution to the associated homogeneous differential equation is y_h = c₁ cos(4x) + c₂ sin(4x), where c₁ and c₂ are arbitrary constants.

a-To find the most general solution to the associated homogeneous differential equation y" + 16y = 0, we assume a solution of the form

[tex]y_h = e ^{rx}[/tex]

Substituting this into the differential equation, we get the characteristic equation r² + 16 = 0, which has roots r = ±4i.

Therefore, the general solution to the homogeneous equation is y_h = c₁ cos(4x) + c₂ sin(4x), where c₁ and c₂ are arbitrary constants.

b-To find a particular solution to the nonhomogeneous differential equation y" + 16y = sec(4x), we use the method of variation of parameters. We assume a particular solution of the form

[tex]y_p = u₁(x) cos(4x) + u₂(x) sin(4x)[/tex]

Substituting this into the differential equation, we get the system of equations

[tex]u₁'(x) cos(4x) + u₂'(x) sin(4x) = 0[/tex]

and

[tex]u₁'(x) sin(4x) - u₂'(x) cos(4x) = ( \frac{1}{16}) sec(4x)[/tex]

Solving this system of equations,

we get

[tex]u₁(x) = ( \frac{1}{32}) ln|cos(2x)| \\ u₂(x) = ( \frac{1}{8}) sin(4x) ln|cos(2x)|[/tex]

Let a, b, c be positive natural numbers. Determine whether the following statement is true or false: If u > x and v > y then ged(u, v) > ged(x,y). O True O False

Answers

The statement is true, if u > x and v > y then ged(u, v) > ged(x,y).

First, let's define ged(u,v) as the greatest common divisor of u and v.

Assuming that u > x and v > y, we can express u and v as:

u = x + m
v = y + n

where m and n are positive natural numbers.

Now, let's assume that ged(x,y) = d, where d is a positive natural number that divides both x and y.

Therefore, we can express x and y as:

x = dp
y = dq

where p and q are positive natural numbers.

Now, we can express u and v in terms of d as well:

u = dp + m
v = dq + n

Since m and n are positive natural numbers, it follows that ged(u,v) is a positive natural number as well.

Now, we need to show that ged(u,v) > d.

Assume the contrary, i.e. ged(u,v) ≤ d.

This means that there exists a positive natural number k that divides both u and v, and k ≤ d.

Since k divides both u and v, it must also divide their difference:

u - v = (d * p + m) - (d * q + n) = d * (p - q) + (m - n)

Therefore, k must also divide (m - n).

But since m and n are positive natural numbers, we have:

|m - n| < max(m,n) ≤ max(u,v)

Therefore, k cannot divide both (m - n) and max(u,v), which contradicts the assumption that k divides both u and v.

Therefore, our initial assumption that ged(u,v) ≤ d must be false, which means that ged(u,v) > d.

Therefore, the statement is true.

Determine the interval(s) on which the given function is decreasing.

A. (–[infinity], –1) ∪ (0,[infinity])

B. (1, [infinity])

C. (–[infinity], –1) ∪ (1, [infinity])

D. (–1, 0)

Answers

The given function is decreasing on the interval (-1, 3/2).

To determine the intervals on which a function is decreasing, we need to find the values of x for which the function's derivative is negative. If the derivative is negative, then the function is decreasing.

Let's consider each option:

A. (–[infinity], –1) ∪ (0,[infinity])

To find the derivative of the function, we first need to find the function itself. Without knowing the function, we cannot determine the derivative or the intervals on which it is decreasing.

B. (1, [infinity])

Again, we need to know the function to determine its derivative and the intervals on which it is decreasing.

C. (–[infinity], –1) ∪ (1, [infinity])

Similarly, we need to know the function to determine its derivative and the intervals on which it is decreasing.

D. (–1, 0)

Let's assume the function is f(x). To find its derivative, we can use the power rule of differentiation, which states that if f(x) = x^n, then f'(x) = nx^(n-1).

If the given function is decreasing on the interval (-1, 0), then its derivative, f'(x), must be negative on that interval. Therefore, we can set up the inequality f'(x) < 0 and solve for x.

Let's first find the derivative of the function:

f(x) = x^2 - 3x + 2

f'(x) = 2x - 3

Now we can set up the inequality:

2x - 3 < 0

Solving for x, we get:

x < 3/2

So the function is decreasing on the interval (-1, 3/2).

Broker V suggests that Sylvia buy four par value $500 bonds from Trochel Office Supplies, one par value $500 bond from Okaloosa county, and three par value $1,000 bonds from Globin Publishing. Bonds from Trochel Office Supplies are selling at 105.142, Okaloosa county bonds are selling at 85.990, and Globin Publishing bonds are selling at 97.063. If Broker U charges a commission of 2.8% of the market value of the bonds sold and Broker V charges a fee of $65 for each bond sold, which bond package will cost Sylvia less, and by how much? a. Broker V’s bond package will cost Sylvia $366.00 less than Broker U’s. b. Broker V’s bond package will cost Sylvia $205.77 less than Broker U’s. c. Broker U’s bond package will cost Sylvia $156.02 less than Broker V’s. d. Broker U’s bond package will cost Sylvia $361.79 less than Broker V’s.

Answers

Broker U's package costs $156.02 less money than Broker V's package. The Option C is correct.

How do we conclude that Broker U cost less money?

Broker U: 2.8% commission

2 par value bonds $1,000 x 96.674% = $1,933.48

3 par value bond $500 x 109.330% = $1,639.95

2 par value bonds $1,000 x 103.851% = $2,077.02

Silvia's total investment:

= ($1,933.48 + $1,639.95 + $2,077.02) x 1.028

= $5,808.66

Broker V: $65 per bond plus

4 par value bonds $500 x 105.142% = $2,102.84

1 par value bond $500 x 85.990% = $429.95

3 par value bonds $1,000 x 97.063% = $2,911.89

Silvia's total investment:

= $2,102.84 + $429.95 + $2,911.89 + (8 x $65)

= $5,964.68

By how much of less that these bond package cost is:

= Broker V's offer - Broker U's offer

= $5,964.68 - $5,808.66

Answers

Matter has mass and occupies space (volume).

The mass of an object is a measure of the amount of matter it contains, while the volume is a measure of the amount of space it occupies. These properties are fundamental to our understanding of the physical world and play a central role in many scientific disciplines, including physics, chemistry, and materials science.

Proton is a subatomic particle with a positive charge.

A proton is a subatomic particle that is found in the nucleus of an atom and has a positive electric charge. Its symbol is "p" or "p+" and its charge is equal in magnitude to that of an electron but with a positive sign. The number of protons in an atom's nucleus determines its atomic number and its identity as a specific element.

Atomic number represents the number of protons.

The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It is also the number of electrons that surround the nucleus in a neutral atom. The atomic number is a unique identifier for each element, and elements are arranged in the periodic table based on their atomic number.

Atom is the simplest form of matter or basic unit.

An atom is the basic unit of matter and is considered the simplest form of matter. It consists of a central nucleus made up of positively charged protons and electrically neutral neutrons, surrounded by negatively charged electrons that orbit the nucleus. The number of protons in the nucleus determines the atom's identity as a particular element, while the number of electrons determines its chemical behavior.

Mixtures are separated by physical means.

Mixtures are combinations of two or more substances that are physically combined but not chemically bonded. Since the substances in a mixture retain their individual properties and can be separated by physical means, mixtures are different from compounds, which are chemically bonded substances that cannot be separated by physical means.

Compounds consist of two or more elements.

Compounds are substances made up of two or more different elements that are chemically bonded together in a fixed ratio. In other words, the elements in a compound are combined in a specific way through chemical reactions to form a new substance with its own unique properties.

Metals will conduct electricity.

Metals are generally good conductors of electricity. This is due to the unique properties of the metallic bond, which is the bond that holds the metal atoms together in a solid.

Electron has a negative charge.

Electrons are negatively charged subatomic particles that are found in orbit around the nucleus of an atom. They have a relative charge of -1 and a mass that is approximately 1/1836th that of a proton. The number of electrons in an atom determines its chemical behavior and reactivity, as well as its electrical conductivity and other physical properties.

Neutron is an uncharged atomic particle.

A neutron is a subatomic particle that is found in the nucleus of an atom, alongside protons. Unlike protons, however, neutrons are electrically neutral, meaning they have no electrical charge. Neutrons have a mass that is slightly larger than that of protons but they do not contribute to the atomic number or the electrical charge of an atom. The stability of the nucleus of an atom is largely determined by the balance between the number of protons and neutrons present.

Nonmetals will not conduct electricity.

The reason for this is that nonmetals typically have high electronegativity, which means they have a strong attraction for electrons and tend to hold onto them tightly. This makes it difficult for electrical current to flow through nonmetallic materials, as the electrons are not free to move around and carry the current.

An arch is in the shape of a parabola. It has a span of 280 meters and a maximum height of 28 meters.

Find the equation of the parabola.

Determine the distance from the center at which the height is 13 meters.​

Answers

The equation of the parabola is given as follows:

y = -28/19600(x - 140)² + 28.

The distances from the center for a height of 13 meters are given as follows:

37.53 m and 242.47 m.

How to obtain the equation of the parabola?

The equation of a parabola of vertex (h,k) is given by the equation presented as follows:

y = a(x - h)² + k.

In which a is the leading coefficient.

It has a span of 280 meters, hence the x-coordinate of the vertex is given as follows:

x = 280/2

x = 140 -> h = 140.

The maximum height is of 28 meters, hence the y-coordinate of the vertex is given as follows:

y = 28 -> k = 28.

Hence the equation is:

y = a(x - 140)² + 28.

When x = 0, y = 0, hence the leading coefficient a is obtained as follows:

19600a = -28

a = -28/19600

Hence:

y = -28/19600(x - 140)² + 28.

The distance from the center at which the height is 13 meters is obtained as follows:

13 = -28/19600(x - 140)² + 28.

28/19600(x - 140)² = 15

(x - 140)² = 15 x 19600/28

(x - 140)² = 10500.

Hence the distances are obtained as follows:

x - 140 = -sqrt(10500) -> x = -sqrt(10500) + 140 = 37.53 m.x - 140 = sqrt(10500) -> x = sqrt(10500) + 140 = 242.47 m.
