5Step-by-step explanation:

The solution for the obtained inequality is x>5. Therefore, option D is the correct answer.

Given that, Shea earns $8 per hour for the first 40 hours she works in a week.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Here,

Total money earned for the first 40 hours she works in a week = 40×8

= $320

Let x be the additional number of hours

So, the inequality which represents the given situation is

320+12x>380

Solve the obtained inequality

12x>380-320

⇒ 12x>60

⇒ x>5

The solution for the obtained inequality is x>5. Therefore, option D is the correct answer.

Darwin's geometric ratio of increase pertains specifically to the growth rate of populations in biological organisms. According to Darwin's theory of evolution, populations have the potential to increase exponentially over time if certain conditions are met. The geometric ratio of increase, often denoted as "r" or the intrinsic rate of natural increase, represents the factor by which a population multiplies during each reproductive cycle or generation.

In the context of natural selection, individuals with higher reproductive rates (higher r-values) have a greater chance of passing on their genetic traits to the next generation. Over time, this can lead to significant population growth and evolutionary changes within a species. However, the geometric ratio of increase is limited by various factors, such as availability of resources, competition, predation, and environmental constraints, which can result in a balance between population growth and environmental carrying capacity.

= tanA/2 proved.

Answer:  see proof below

Step-by-step explanation:

Use the following Double Angle Identities:

sin 2A = 2cos A · sin A

cos 2A = 2 cos²A - 1

Use the following Quotient Identity: tan A = (sin A)/(cos A)

Use the following Pythagorean Identity:

cos²A + sin²A = 1   -->   sin²A = 1 - cos²A

Proof LHS → RHS

Given:                            \(\dfrac{1+sin\theta - cos \theta}{1+sin \theta +cos \theta}\)

Let Ф = 2A:                    \(\dfrac{1+sin2A - cos 2A}{1+sin2A +cos2A}\)

The missing number in the median set is 6.

We are given that;

Median set=18

Now,

To find the missing number, you need to know the number of elements in the set and their order. The median is the middle value of a set when it is arranged in ascending or descending order. If the set has an odd number of elements, the median is the exact middle value. If the set has an even number of elements, the median is the average of the middle two values.

For example, if the set is {2, 4, 6, 8, 10}, the median is 6 because it is the middle value. If the set is {3, 5, 7, 9}, the median is (5 + 7) / 2 = 6 because it is the average of the middle two values.

Therefore, by median the answer will be 6.

Approximately 24.3% of Johnson & Johnson's profits in 2009 were due to mothers who are Hispanic.

To calculate the percentage of Johnson & Johnson's profits due to mothers who are Hispanic, we divide the amount of money spent by Hispanic mothers by the total sales and then multiply by 100 to express it as a percentage.

Amount spent by Hispanic mothers = $3,150,367

Total sales = $12,949,847

Percentage = (Amount spent by Hispanic mothers / Total sales) * 100

Percentage = ($3,150,367 / $12,949,847) * 100

Percentage ≈ 24.3%

Therefore, approximately 24.3% of Johnson & Johnson's profits in 2009 were due to mothers who are Hispanic.

The value where the histogram balances when supported at that point is called the mode of the distribution.

The mode of distribution is the value that appears most frequently in the data set. It is often used as a measure of central tendency, along with the mean and median. The mode is especially useful when dealing with categorical or discrete data, where the possible values are limited and well-defined.

For example, the mode of a list of test scores might be the score that occurs most frequently, indicating the most common level of performance. In a histogram, the mode is the value where the distribution is highest, or where the histogram balances when supported at that point.

the function y = f(x) that satisfies the given conditions is y = 2x^3 - x^2 - 5x + C2, where C2 is a constant that can take any real value.

First, integrate y' with respect to x to find the first derivative y:

∫(y') dx = ∫(12x - 2) dx

y = 6x^2 - 2x + C1

Next, integrate y with respect to x to find the function f(x):

∫y dx = ∫(6x^2 - 2x + C1) dx

f(x) = 2x^3 - x^2 + C1x + C2

To determine the specific values of C1 and C2, we use the given condition that the line y = -x + 5 is tangent to the graph at x = 1.

Since the tangent line has the same slope as the function f(x) at x = 1, we can equate their derivatives:

f'(1) = -1

Taking the derivative of f(x), we have:

f'(x) = 6x^2 - 2x + C1

Substituting x = 1 and equating f'(1) to -1, we can solve for C1:

6(1)^2 - 2(1) + C1 = -1

6 - 2 + C1 = -1

C1 = -5

Now we have the values of C1 and C2. Plugging them back into the equation for f(x), we obtain the final function:

f(x) = 2x^3 - x^2 - 5x + C2

The probability of winning by picking the number 30 in roulette is 1/38.

In the game of roulette, the wheel consists of 38 spaces, with numbers 0 through 36 and an additional space marked 00. When you pick a specific number, such as 30, the probability of that number coming up on the wheel can be determined by calculating the ratio of favorable outcomes to the total number of possible outcomes.

In this case, there is only one favorable outcome, which is the ball landing on the number 30. The total number of possible outcomes is 38 since there are 37 numbered spaces (0 through 36) and one additional space for 00. Therefore, the probability of winning by picking the number 30 is 1 out of 38.

To put it simply, if you were to play roulette many times, you would expect the number 30 to come up approximately once every 38 spins on average. This probability remains the same for each individual spin, as each spin of the roulette wheel is an independent event.

The concept that a message gives different meanings to different objects is called option (b) polymorphism.

Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows different objects to respond to the same message or method invocation in different ways. In other words, it allows objects of different classes to be treated as if they were of the same class, as long as they implement the same method or message.

This can make code more flexible, reusable, and easier to maintain. Polymorphism is achieved through inheritance, interfaces, or overloading methods. For example, a "draw" method could be implemented differently for different shapes, such as circles, rectangles, or triangles.

Therefore, the correct option is (b) polymorphism

when were given a point (x,y), we write our equation in the y = mx + b form, then substitute the given point for (x,y) and solve for B!

However, to find the slope of the perpendicular equation, you need to get the negative reciprocal of the slope!

The probability of this event of getting a queen when selecting 49 cards from a shuffled deck is represented by a value of 1.

The probability of an occurrence can be determined using the probability formula by only dividing the favorable number of possibilities by the entire number of possible outcomes.

Given that the favorable number of outcomes can never exceed the total number of outcomes, the chance of an event occurring can range from 0 to 1. Therefore, there cannot be any unfavorable outcomes.

In the given question,

Out of 52 cards in the deck, when selecting 49 cards the event of getting a queen is only once.

The likelihood of an occurrence that is regarded as certain, or absolutely certain to occur, is 100% = 1.

The 49 cards you choose from a shuffled deck will all be queens, so you can be sure of that.

This indicates that a value of 1 represents the probability of this event.

The space enclosed by the sector of a circle is called the area of the sector.

the radius of the circle is 5cm.

area of arc =  radius² × θ/2

area of the arc is =  5² × 4π/9 = 25 × 4/9 = 34.88

area of the triangle inside circle = a×b × sin(y)/2

area of triangle = 5×5 × sin(80°)/2 = 25 × 0.492
