Ngoc should predict that the home is located in Smavile based on the real estate advertisement

From the question, we have the following parameters that can be used in our computation:

Function 1: p = 150 + 0.041a (Smavile)

Function 2: p = 250 + 0.198a (Fancyville )

Where

a = area

p = price

From the question, we have

a = area = 2800

p = price = 280000

Using the above as a guide, we have the following:

So, we have

Function 1: p = 150 + 0.041 * 2800 (Smavile)

Evaluate the expression

p = 264.8 -- false

Function 2: p = 250 + 0.198 * 2800 (Fancyville )

Evaluate the expression

p = 804.4 --- false

264.8  is closer to 280 than 804.4

Hence, the home is in Smavile

Answer:

The girl read 1,159 - 72 = 1,087 pages after the first day.

Let d be the number of days after the first day that she took to finish the book.

The total number of pages she read on these d days is 40d.

The equation that can be used to find how many more days it took her to read the book after the first day is:

40d = 1,087

Solving for d:

d = 1,087/40

d ≈ 27.175

Therefore, it took her approximately 27 more days to finish reading the book after the first day.

Answer:

Mean =          15.83 hours

Median =  17 hours

Step-by-step explanation:

The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.

Once this is done, we have the responses as

responses: 9. 14, 16, 18, 19, 19

The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.

this is \(9 +14 + 19 + 18 + 16 + 14 + 19/ 6= 95/6 = 15.83\)

The mean of the distribution is 15.83 hours

The median is obtained by picking out the middle number of the distribution.  However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2

= (16 + 18 )/2 = 34/2 = 17

Answer:

(a) The average television hours for the six students in the previous week    was 15.83 Hours.

(b) The median number of hours would be 17 Hours

Step-by-step explanation:

Mean

The mean of a group of numbers is the average of the numbers. The mean can be gotten with the expression in equation 1.

Mean = Σx / n ...............1

Where Σx is the sum of the numbers

n is the number of values

Substituting our values into equation 1 we have;

Mean = (19+9+18+ 16+14+19) ÷ 6

Mean = 95 ÷ 6

= 15.83 Hours

Therefore the average television hours for the six students in the previous week were 15.83 Hours.

The median of a group of numbers is the middle term of the numbers when arranged in ascending or descending order.

Given the television hours of the six students, we have;

19, 9, 18, 16, 14, 19

We arrange the numbers in ascending order from the smallest to the biggest;

9, 14, 16, 18, 19, 19

Since the number of value is even the median would be obtained by finding the mean of the two middle terms.

From our arranged data, 9, 14, 16, 18, 19, 19

the two middle numbers are 16, 18

Therefore the mean would be

(16+18) /2

=34/2

= 17 hours

Thus the median number of hours would be 17 Hours

By using properties of parallel lines, the results obtained are

x = 80°, y = 130°

What are parallel lines?

Parallel lines

Two lines are said to be parallel if on extending them indefinitely, they will never intersect

Transversal is a line that intersects two or more parallel lines

Here, by using properties of parallel lines,

x + 50 + x - 30 = 180 [Co interior angles are supplementary]

2x + 20 = 180

2x = 180 - 20

2x = 160

x = \(\frac{160}{2}\\\)

x = 80°

x - 30 + y = 180 [Co interior angles are supplementary]

80 - 30 + y = 180

50 + y = 180

y = 180 - 50

The probability that between 31.2% and 50.4% of the students in the sample will be minority students is approximately 0.7154, or 71.54%.

To solve this problem, we can use the normal approximation to the binomial distribution, assuming that the sample size is large enough. The mean (μ) of the binomial distribution is given by n * p, where n is the sample size and p is the probability of success. In this case, the sample size is 100 and the probability of success is 0.36.

μ = n * p = 100 * 0.36 = 36

The standard deviation (σ) of the binomial distribution is given by the square root of n * p * (1 - p).

σ = √(n * p * (1 - p)) = √(100 * 0.36 * (1 - 0.36)) ≈ 4.16

To calculate the probability between 31.2% and 50.4%, we need to convert these percentages into z-scores using the formula:

z = (x - μ) / σ

where x is the observed value, μ is the mean, and σ is the standard deviation.

For 31.2%:

z1 = (31.2 - 36) / 4.16 ≈ -1.06

For 50.4%:

z2 = (50.4 - 36) / 4.16 ≈ 3.37

Next, we need to find the cumulative probabilities associated with these z-scores using a standard normal distribution table or calculator. The cumulative probability can be interpreted as the area under the normal curve up to a given z-score.

P(31.2% ≤ x ≤ 50.4%) = P(-1.06 ≤ z ≤ 3.37)

Using a standard normal distribution table or calculator, we can find the corresponding cumulative probabilities:

P(-1.06 ≤ z ≤ 3.37) ≈ 0.8577 - 0.1423 ≈ 0.7154

Therefore, the probability that between 31.2% and 50.4% of the students in the sample will be minority students is approximately 0.7154, or 71.54%.

A differential equation is a type of mathematical equation that connects the derivatives of an unknown function.

The differential equation is 1/2 y₁ = −6y₁ = -2y1 3y2.

The initial conditions are

y₁(0) = 5, y2(0) = 3.

The solution of the differential equation is: First we solve the differential equation for

y1:1/2 y₁ = −6y₁−2y1⇒

1/2y₁ + 6y₁ = 0+2y₁⇒

13/2 y₁ = 0⇒

y₁ = 0.

Therefore, y₁(x) = 0 is the solution to the differential equation. Now we solve the differential equation for

y2:3y2 = 0⇒

y2 = 0.

Therefore, y2(x) = 0 is the solution to the differential equation. The initial conditions are

y₁(0) = 5, y2(0) = 3.

So the solution to the differential equation subject to the initial conditions is

y₁(x) = 5 and

y2(x) = 3.

The functions y₁(x) and y2(x) (in that order) are:

y₁(x) = 5, y2(x) = 3.

First and foremost, it is important to note that human skin color is determined by a variety of factors, including genetics, environmental influences, and geographic location. In fact, skin color is the result of the amount and type of melanin pigment produced by specialized cells in the skin called melanocytes.

There are two main types of melanin pigment: eumelanin and pheomelanin. Eumelanin is responsible for producing darker skin colors, while pheomelanin produces lighter skin colors. However, the amount and distribution of these pigments can vary greatly between individuals, resulting in a wide range of skin tones.

Additionally, skin color can also be influenced by factors such as sun exposure, age, and hormonal changes. For example, prolonged sun exposure can lead to darker skin, while aging and hormonal changes can cause changes in skin pigmentation. Furthermore, it is important to note that skin color is not always clearly defined or easily categorized into specific shades. There can be a great deal of variation within a single skin tone, as well as overlap between different skin tones. This is due to the complex interplay of genetic and environmental factors that contribute to skin color.

If X = 1, then select three cards of the same kind, that can only be a set of three jacks or three queens or three kings, or three aces.

P (Y = 3 | X = 1) = 4/220 = 1/55

If X = 2, then we are selecting two cards of one kind and one card of another kind. The first kind can be any of the four face card denominations, and the second kind can be any of the remaining three face card denominations. So, the number of possible sets is 4 × 3 = 12.

P (Y = 2 | X = 2) = 24/220 = 3/55

If X = 3, then we are selecting one card of each of three different kinds. The first kind could be any of the four face card denominations, the second kind could be any of the three remaining face card denominations, and the third kind can be any of the two remaining face card denominations.

P (Y = 1 | X = 3) = 1536/220 = 12/55

Step-by-step explanation:

The likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%

When dealing with normally distributed data, we use the mean and standard deviation to determine the likelihood of certain events occurring. In this case, the mean weight of bags of cement is 53 with a standard deviation of 2.

To find the likelihood that a randomly selected bag has a weight greater than 50, we need to calculate the z-score for 50. The z-score tells us how many standard deviations away a particular value is from the mean.

z = (X - μ) / σ

where X is the value we're interested in (50), μ is the mean (53), and σ is the standard deviation (2).

z = (50 - 53) / 2 = -1.5

A z-score of -1.5 means that a weight of 50 is 1.5 standard deviations below the mean. To find the likelihood of a bag weighing more than 50, we can use a z-table or a calculator to find the area to the right of this z-score.

Looking up a z-score of -1.5, we find that the area to the left is approximately 0.0668, which means the area to the right (the likelihood of a bag weighing more than 50) is:

1 - 0.0668 = 0.9332

Thus, the likelihood that a randomly selected bag of cement weighs more than 50 is approximately 93.32%.
