The statement says that if the result is even integer (like 2, 4, 6, ...) then x and y also are. If we want to disprove that, we need to look for a even integer that have x and/or y not even integer.
All alternatives but c have even integers as result, but only d show x and y odd integers.
So, "d" clearly disproves the statement, because they show that the sum of two odd integers (1 and 3) results in an even integer (4), which contradicts the statement.
given the following: d: μ≥1000; e: μ<1000 d and e represent respectively.
Based on the information provided, d and e represent different statistical hypotheses about a population mean, denoted by. Specifically, the hypothesis d states that the population mean is greater than or equal to 1000, while the hypothesis e states that the population mean is less than 1000.
To put this into context, let's say that we are interested in studying the average income of workers in a certain city. We can collect a sample of data from a random sample of workers in the city, calculate the sample mean, denoted by x, and use it to make inferences about the population mean,. If we want to test the hypothesis that the average income is at least 1000 dollars, we can set up the null hypothesis as d: 1000 and the alternative hypothesis as not d: 1000. This means that we assume the population mean is 1000 or greater, and we want to see if there is enough evidence in the data to reject this hypothesis in favor of the alternative.
On the other hand, if we want to test the hypothesis that the average income is less than 1000 dollars, we can set up the null hypothesis as e: 1000 and the alternative hypothesis as not e: 1000. In this case, we assume the population mean is less than 1000, and we want to see if the data provide enough evidence to reject this hypothesis in favor of the alternative.

Using the relation speed = distance / time, the different values of time , speed and distance are given below -
What connection exists between movement and distance?So, speed equals distance times time. The time can also be calculated by dividing the distance travelled by the speed. If you are aware of two of the inputs, you can determine the third one. For instance, we may get the speed as 120 x 2 = 60 miles per hour if a car travels 120 miles in two hours.
The total movement of an object, independent of direction, is its distance. The amount of space that an object has travelled, regardless of where it started or ended, is referred to as distance. How quickly or slowly an object is travelling is determined by its speed.

Find the area of the surface generated when the given curve is revolved about the given axis. y = 4x – 4, for 3/2≤ X ≤ 7/2 about the y-axis (Hint: Integrate with respect to y.)
The area of the surface generated when the curve y = 4x - 4, for 3/2 ≤ x ≤ 7/2, is revolved about the y-axis is 21π√17 square units.
To find the area of the surface generated when the curve y = 4x - 4, for 3/2 ≤ x ≤ 7/2, is revolved about the y-axis, we can use the formula:
A = 2π ∫ y * ds
where A is the surface area, y is the function that defines the curve, and ds is an element of arc length on the surface of revolution.
To integrate with respect to y, we need to solve the equation for x in terms of y:
y = 4x - 4
4x = y + 4
x = (y + 4)/4
Next, we need to express ds in terms of y. Since we are revolving the curve about the y-axis, ds is given by:
ds = √(dx/dy)^2 + 1 dy
where dx/dy is the derivative of x with respect to y. Taking the derivative of x with respect to y, we get:
dx/dy = 1/4
Substituting this in the equation for ds, we get:
ds = √(1/16 + 1) dy = √(17)/4 dy
Now, we can use the formula for the surface area:
A = 2π ∫ y * ds = 2π ∫ y √(17)/4 dy
We need to express y in terms of x to determine the limits of integration. From the equation y = 4x - 4, we have:
x = (y + 4)/4
Solving for y, we get:
y = 4x - 4
Substituting the limits of integration, we get:
A = 2π ∫ (4x - 4) √(17)/4 dx from x = 3/2 to x = 7/2
Simplifying, we get:
A = π√17 ∫ (4x - 4) dx from x = 3/2 to x = 7/2
A = π√17 [2x^2 - 4x] from x = 3/2 to x = 7/2
A = π√17 [(2(7/2)^2 - 4(7/2)) - (2(3/2)^2 - 4(3/2))]
A = 21π√17

which of the following best explans why the monopolists marginal revenue is less than the sales price
Monopolists are firms that have control over the supply of a particular product or service in a market. Due to this control, they can charge higher prices than competitive firms, which can result in lower quantities sold.
One reason why a monopolist's marginal revenue is less than the sales price is due to the downward-sloping demand curve. As the monopolist increases its sales price, the quantity demanded decreases. This means that the revenue generated from each additional unit sold is lower than the revenue generated from the previous unit sold. In other words, the marginal revenue earned from each unit sold is less than the sales price. This occurs because the monopolist must lower the price of all units sold to sell additional units, which lowers the average revenue earned per unit.
To illustrate this, imagine a monopolist that sells widgets for $10 each. If the monopolist lowers the price to $9, it may sell 10 widgets, resulting in revenue of $90 ($9 x 10). However, if the monopolist maintains the $10 price and only sells 9 widgets, the revenue is $90 ($10 x 9). In this case, the marginal revenue for the 9th unit sold is $0, which is less than the sales price of $10. This is because the monopolist must lower the price of all units sold to sell the additional unit, resulting in a decrease in average revenue per unit. Overall, the monopolist's marginal revenue is less than the sales price due to the downward-sloping demand curve and the need to lower prices to sell additional units.
A monopolist, unlike firms in a competitive market, has significant market power due to the absence of competition. This allows the monopolist to control the market price of their product by adjusting the quantity supplied. When a monopolist wants to sell an additional unit, they must lower the sales price for all units, including the ones already being sold. This is because the demand curve faced by a monopolist is downward-sloping, meaning that in order to sell more units, the monopolist has to decrease the price.
Marginal revenue refers to the additional revenue gained from selling one more unit of the product. As the monopolist lowers the sales price to sell more units, two things happen: the revenue increases from the additional unit sold, but there is also a loss in revenue from the units that were sold at a higher price before the price reduction.
As a result, the marginal revenue is less than the sales price, since it takes into account not only the revenue from the additional unit sold but also the loss of revenue from lowering the price of all units. This relationship between the monopolist's pricing strategy and marginal revenue is a key factor in determining the monopolist's profit-maximizing level of output and price.

you toss a biased coin, where the probability of heads is 70%. your first toss is tails. what is the expected number of flips until you flip the same number of heads and tails
The expected number of flips until you flip the same number of heads and tails is approximately 2.586 flips.
To determine the expected number of flips until you flip the same number of heads and tails, we can analyze the possible outcomes and their probabilities. Let's denote H as heads and T as tails.
In this scenario, we have a biased coin with a 70% probability of landing on heads (H) and a 30% probability of landing on tails (T). Since the first toss is tails, we need to calculate the expected number of flips until we get an equal number of heads and tails.
Let's consider the possible sequences of flips that can lead to an equal number of heads and tails:
HT: This sequence occurs with a probability of 0.3 * 0.7 = 0.21.
HTH: This sequence occurs with a probability of 0.3 * 0.7 * 0.3 = 0.063.
HTHT: This sequence occurs with a probability of 0.3 * 0.7 * 0.3 * 0.7 = 0.0441.
HTHTH: This sequence occurs with a probability of 0.3 * 0.7 * 0.3 * 0.7 * 0.3 = 0.01323.
HTHTHT: This sequence occurs with a probability of 0.3 * 0.7 * 0.3 * 0.7 * 0.3 * 0.7 = 0.009261.
We can observe that each sequence has an equal number of heads and tails, so we need to calculate the expected value by multiplying each sequence's length by its respective probability and summing them up:
Expected value = (2 * 0.21) + (3 * 0.063) + (4 * 0.0441) + (5 * 0.01323) + (6 * 0.009261) = 2.1 + 0.189 + 0.1764 + 0.06615 + 0.055566 = 2.586116.
