The probability of selecting a four-digit number greater than 1499 from the set of numbers from 1000 to 1999 is 500/1000 = 0.5 = 50%.

There are 1000 numbers from 1000 to 1999, and half of them (500) are greater than 1499. Therefore, the probability of selecting a number greater than 1499 is 500/1000 = 0.5 = 50%.

In addition to the summary, here is a more detailed explanation of the answer:

The probability of an event occurring is calculated by dividing the number of desired outcomes by the total number of possible outcomes. In this case, the desired outcome is selecting a number greater than 1499, and the total number of possible outcomes is selecting any number from 1000 to 1999. There are 500 numbers from 1000 to 1999 that are greater than 1499, so the probability of selecting one of these numbers is 500/1000 = 0.5 = 50%.

We can compute various descriptive statistics such as the mean, median, mode, range, variance, standard deviation, sum of values, and sum of squared deviations.

The sample mean, also known as the average, provides information about the central tendency of the variable X. It represents the typical or average number of coupons used by the shoppers in the sample. In this case, calculating the mean of the given data would provide an estimate of the average number of coupons used over the 6-month period.

The sample standard deviation measures the dispersion or variability of the data points around the mean. It indicates how much the individual observations deviate from the mean value. A higher standard deviation implies greater variability, indicating a wider range of coupon usage among the shoppers in the sample.

By computing the sample mean and standard deviation, we can understand the average coupon usage and the degree of variability in the data. These statistics help us summarize and interpret the characteristics of the variable X, allowing us to make comparisons, identify outliers, assess the spread of the data, and make inferences about the larger population from which the sample was drawn.

The negative skewness implies that the distribution is not symmetrical. The longer left tail suggests a larger proportion of households with lower incomes compared to those with higher incomes.

Based on the given information, we can make the following observations about the distribution of incomes of American households in the city in 1984:

1. Skewness: Since the median ($48,000) is greater than the mean ($44,000), it suggests that the distribution of incomes is negatively skewed or left-skewed. This means that there are relatively more households with lower incomes, pulling the median higher than the mean.

2. Outliers: The presence of outliers, particularly high-income households, could also contribute to the difference between the mean and median. These outliers would increase the mean but have less effect on the median.

3. Spread: The information provided does not give any direct indication of the spread or variability of the income distribution. We cannot determine from this data whether the distribution is narrow or wide.

4. Symmetry: The negative skewness implies that the distribution is not symmetrical. The longer left tail suggests a larger proportion of households with lower incomes compared to those with higher incomes.

It's important to note that the given information only provides a snapshot of the income distribution in one specific American city in 1984. It does not represent the entire country or the current situation.

Step-by-step explanation:

one gallon is 128oz.

1445 gallons are how many Oz?

that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"

or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"

it all works with multiplication. it is the ultimate application for multiplication.

that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.

and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.

The absolute maximum and minimum values of the function f(x, y) = x^2 + y^2 - 2y on the set R = {(x, y): x^2 + y^2 ≤ 9} can be found by analyzing the critical points and the boundary of the region R.

To find the critical points, we take the partial derivatives of f(x, y) with respect to x and y, and set them equal to zero. Solving these equations, we find that the critical point occurs at (0, 1).

Next, we evaluate the function f(x, y) at the boundary of the region R, which is the circle with radius 3 centered at the origin. This means that we need to find the maximum and minimum values of f(x, y) when x^2 + y^2 = 9. By substituting y = 9 - x^2 into the function, we obtain f(x) = x^2 + (9 - x^2) - 2(9 - x^2) = 18 - 3x^2.

Now, we can find the maximum and minimum values of f(x) by considering the critical points, which occur at x = -√2 and x = √2. Evaluating f(x) at these points, we get f(-√2) = 18 - 3(-√2)^2 = 18 - 6 = 12 and f(√2) = 18 - 3(√2)^2 = 18 - 6 = 12.

Therefore, the absolute maximum value of f(x, y) is 12, which occurs at (0, 1), and the absolute minimum value is also 12, which occurs at the points (-√2, 2) and (√2, 2).

d) The probability that a car with an alarm system had a CD player is 0.786.

e) No, having a CD player and an alarm system are not disjoint events.

a. The Venn Diagram for the scenario can be created as follows:

Attached

b. To find the probability that a randomly selected car had neither a CD player nor an alarm system, we need to find the complement of the event "having either a CD player or an alarm system."

P(neither CD player nor alarm system) = 1 - P(CD player or alarm system)

Since the events "CD player" and "alarm system" are not mutually exclusive (they can both occur), we need to subtract the probability of the intersection of the two events.

P(neither CD player nor alarm system) = 1 - P(CD player or alarm system) = 1 - P(CD player) - P(alarm system) + P(CD player and alarm system)

P(neither CD player nor alarm system) = 1 - 0.640 - 0.280 + 0.220 = 0.300

Therefore, the probability that a randomly selected car had neither a CD player nor an alarm system is 0.300.

c. To find the probability that a car had a CD player unprotected by an alarm system, we need to subtract the probability of having both a CD player and an alarm system from the probability of having a CD player.

P(CD player unprotected by alarm system) = P(CD player) - P(CD player and alarm system) = 0.640 - 0.220 = 0.420

Therefore, the probability that a car had a CD player unprotected by an alarm system is 0.420.

d. To find the probability that a car with an alarm system had a CD player, we need to divide the probability of having both a CD player and an alarm system by the probability of having an alarm system.

P(CD player given alarm system) = P(CD player and alarm system) / P(alarm system) = 0.220 / 0.280 = 0.786

Therefore, the probability that a car with an alarm system had a CD player is 0.786.

e. No, having a CD player and an alarm system are not disjoint events. Disjoint events are events that cannot occur simultaneously. In this case, 22% of the cars had both a CD player and an alarm system, indicating that these events can occur together. Disjoint events have a probability of intersection equal to zero, but in this scenario, the probability of having both a CD player and an alarm system is 0.220, indicating that they are not disjoint.

Answer:

When we say that an allele is "fixed," it means that a particular allele has reached a frequency of 100% in a population.

Step-by-step explanation:

Alleles are different forms of a gene that occupy the same position on homologous chromosomes. In a population, different alleles can exist for a specific gene. However, through various evolutionary processes such as natural selection, genetic drift, or gene flow, one allele may become predominant and eventually fixate within the population.

The fixation of an allele can occur through different mechanisms. For example, if a beneficial allele provides a selective advantage to individuals carrying it, it is more likely to increase in frequency and eventually become fixed in the population. On the other hand, genetic drift, which is the random change in allele frequencies due to chance events, can also lead to the fixation of an allele, especially in small populations.

Once an allele is fixed in a population, it means that all future generations will inherit that allele, and no alternative alleles will be present at that particular gene locus.

The probability distribution at each point x along the horizontal axis.

For a Normal distribution with mean 0 and standard deviation 1,

the following Python line outputs the probability p(-0.15 < x < 1.88):

print(st.norm.cdf(1.88, 0, 1) - st.norm.cdf(-0.15, 0, 1))

Probability is the likelihood or chance that an event will occur. It is a number between 0 and 1, with 0 indicating that an event will never occur and 1 indicating that an event will always occur.

Probability values range from 0 to 1, with a value of 0 indicating that the event will never occur and a value of 1 indicating that the event will always occur.

The probability is the value between 0 and 1 that indicates the likelihood of an event occurring. The probability is obtained by dividing the number of ways an event can occur by the total number of possible outcomes.

(a) The firm's output supply function is given by q = (p + 199) / 2.

(b) The market-equilibrium price is $32.56, and the equilibrium number of firms is 10.

(c) Each firm sells 70 computers in the long run.

(39 - 0.009q) = (2q - 2) / q

Simplifying the equation, we find:

q = (p + 199) / 2

This represents the firm's output supply function.

p = 39 - 0.009((p + 199) / 2)

Simplifying and solving for p, we get:

p ≈ $32.56

Substituting this price back into the output supply function, we find:

q = (32.56 + 199) / 2 ≈ 115.78

Given that each firm produces 70 computers in the long run, we can calculate the equilibrium number of firms:

Number of firms = q / 70 ≈ 10

x² + 576 = 625 ( subtract 576 from both sides )

x² = 49 ( take square root of both sides )

x = \(\sqrt{49}\) = 7

Hey ! there

Answer:

Step-by-step explanation:

In this question we are provided with a right angle triangle having hypotenuse 25 cm , base 24 cm and perpendicular x . And we are asked to find the length of x .

For finding the length of x we'll use Pythagorean Theorem . Pythagorean Theorem states that sum of square of perpendicular and base is equal to the square of hypotenuse in right angle triangle that is ,

\( \: \qquad \: \qquad \: \underline{\boxed{ \frak{H {}^{2} = P {}^{2} + B {}^{2} }}}\)

Where ,

SOLUTION : -

Here in the triangle ,

Applying Pythagorean Theorem :

\( \quad \longmapsto \qquad \: (25) {}^{2} = (x ){}^{2} + (24) {}^{2} \)

On squaring 24 and 24 we get ,

\( \quad \longmapsto \qquad \:625 = (x) {}^{2} + 476\)

Subtracting 576 on both sides :

\( \quad \longmapsto \qquad \:625 - 576 = (x) {}^{2} + \cancel{ 576} - \cancel{576}\)

We get ,

\( \quad \longmapsto \qquad \:49 = (x) {}^{2} \)

Applying square root on both sides :

\( \quad \longmapsto \qquad \: \sqrt{49} = \sqrt{(x) {}^{2} } \)

We get ,

\( \quad \longmapsto \qquad \: \blue{ \underline{\boxed{\frak{7 \: cm = x}}}} \quad \bigstar\)

We are verifying our answer by substituting all the values of hypotenuse , perpendicular and base in Pythagorean Theorem . So ,

Therefore, our answer is correct .
