The postulate or property that can be used to prove that Kimball is not between Scottsbluff and Sidney is the Segment Addition Postulate.

The Segment Addition Postulate states that for three points A, B, and C, where B is between A and C,

            we have AB + BC = AC.

Given that Kimball is not between Scottsbluff and Sidney, this means that Kimball is either to the west of Scottsbluff or to the east of Sidney.

Let's assume that Kimball is to the west of Scottsbluff.

Then, we can draw the line segment as follows:

Scottsbluff ——————— Kimball ——————— Sidney

Let AB represent the distance between Scottsbluff and Kimball, and let BC represent the distance between Kimball and Sidney. According to the Segment Addition Postulate, AB + BC = AC, where AC is the distance between Scottsbluff and Sidney.

However, if we draw the line segment from Scottsbluff to Sidney without Kimball, we can see that the distance between the two points will always be shorter than the sum of the distances from Scottsbluff to Kimball and from Kimball to Sidney.

This implies that if Kimball is not between Scottsbluff and Sidney, then it is not possible for the segment addition postulate to hold true for the three points.

Therefore, we can use the segment addition postulate to prove that Kimball is not between Scottsbluff and Sidney.

The assumption about normality is investigated by looking at a qq plot in a t-test. Therefore, the answer is e. normality assumption.

The qqplot helps to assess whether the sample data are normally distributed, which is an important assumption for the t-test to be valid. If the data deviate significantly from normality, then the t-test results may not be reliable.

Therefore, by examining a QQ plot, one can determine whether the data deviate from normality. If the data points in the QQ plot fall close to the diagonal line, it indicates that the data are normally distributed. If the points deviate from the diagonal line, it suggests that the data may not be normally distributed, and further investigation or alternative statistical tests may be necessary.

Answer:

The distance between 2 points is 16.1 units.

Step-by-step explanation:

You have to apply distance formula using coordinates,

\(distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \)

Let (x1,y1) be (-6,2),

Let (x2,y2) be (8,10)

\(distance = \sqrt{ {(8 - ( - 6))}^{2} + {(10 - 2)}^{2} } \)

\(distance = \sqrt{196 + 64} \)

\(distance = \sqrt{260} \)

\(distance = 2 \sqrt{65} \)

(a) The semiannual payment to amortize this loan is $517.42

(b) total amount of the payments is $1813.56

(c) total payment from the amortization table is $9313.56, and the total interest paid is $1813.56.

To calculate the semiannual payment, total payments, total interest paid, and the amortization table for the given loan, use the formula for calculating the payment amount on an amortizing loan:

Payment = Principal × (r × (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

Where:

Principal = $7500 (loan amount)

r = interest rate per compounding period = 6.9% / 2 = 0.069 / 2 = 0.0345 (since the interest is compounded semiannually)

n = total number of compounding periods = 18

(a) Calculate the semiannual payment:

Payment = $7500 × (0.0345 × (1 + 0.0345)¹⁸) / ((1 + 0.0345)¹⁸ - 1)

Payment ≈ $517.42

(b) Calculate the total payments:

Total payments = Payment × n

Total payments ≈ $517.42 × 18

Total payments ≈ $9313.56

To calculate the total amount of interest paid, subtract the loan amount from the total payments:

Total interest paid = Total payments - Principal

Total interest paid ≈ $9313.56 - $7500

Total interest paid ≈ $1813.56

(c) To create an amortization table, calculate the payment schedule for each compounding period and track the remaining balance. Here is the amortization table:

Payment No. Payment Interest Principal Remaining Balance

1 $517.42 $258.75 $258.67 $7241.33

2 $517.42 $248.84 $268.58 $6972.75

3 $517.42 $238.46 $279.96 $6692.79

... ... ... ... ...

18 $517.42 $12.42 $505.00 $0.00

The vector function r'(t), r"(t), r'(t) r"(t), and r'(t) x r"(t). is
(a) r'(t) = 3ti - 3j + 15t²k

(b) r"(t) = 3i + 15tk

(c) r'(t) · r"(t) = 9t - 45t²

(d) r'(t) x r"(t) = -90t²i - 45tj - 9k

To find the derivatives of the vector function r(t) = 3²³i - 3tj + 5t³k, we differentiate each component of the vector with respect to t.

(a) To find r'(t), we differentiate each component separately:

r'(t) = (d/dt)(3²³i) - (d/dt)(3tj) + (d/dt)(5t³k)

= 0i - 3j + 15t²k

= 3ti - 3j + 15t²k

(b) To find r"(t), we differentiate each component of r'(t) with respect to t:

r"(t) = (d/dt)(3ti) - (d/dt)(3j) + (d/dt)(15t²k)

= 3i + 0j + 15tk

= 3i + 15tk

(c) To find r'(t) · r"(t), we take the dot product of r'(t) and r"(t):

r'(t) · r"(t) = (3ti - 3j + 15t²k) · (3i + 15tk)

= 9t - 45t²

(d) To find r'(t) x r"(t), we take the cross product of r'(t) and r"(t):

r'(t) x r"(t) = (3ti - 3j + 15t²k) x (3i + 15tk)

= -90t²i - 45tj - 9k

In summary, r'(t) = 3ti - 3j + 15t²k, r"(t) = 3i + 15tk, r'(t) · r"(t) = 9t - 45t², and r'(t) x r"(t) = -90t²i - 45tj - 9k.

The correct is option c) meridian. The measures of central tendency are used to describe the middle or typical value of a dataset. Mean, median, and mode are the most common measures of central tendency.

Mean is the arithmetic average of a set of values, median is the middle value in a set of values, and mode is the most frequently occurring value in a set of values. These measures are used to summarize the characteristics of a dataset in a single value. On the other hand, the term "meridian" does not refer to a measure of central tendency. It is a term used in geography and navigation to refer to a line of longitude on a map or globe.

In conclusion, meridian is not a measure of central tendency, and mean, median, and mode are commonly used measures of central tendency in statistics.

Buying from Value World would cost Binita £0.72 less (in pounds) than buying from Letters2go.

To compare the costs of envelopes from both shops, we need to calculate the price per envelope.

At Letters2go, the price per envelope is:

3.29 pounds / 25 envelopes = 0.1316 pounds per envelope

At Value World, the price per envelope is:

(1.95 pounds * 2 packs) / (10 envelopes * 2 packs + 1 free pack) = 0.1300 pounds per envelope

So the price per envelope at Value World is slightly less than the price per envelope at Letters2go.

To buy 450 envelopes, Binita would need to purchase:

18 packs of 25 envelopes at Letters2go (18 x 25 = 450 envelopes)

45 packs of 10 envelopes at Value World (45 x 10 = 450 envelopes)

At Letters2go, the cost of 18 packs of 25 envelopes would be:

18 packs x £3.29 per pack = £59.22

At Value World, the cost of 45 packs of 10 envelopes (with 15 packs being free) would be:

30 packs x £1.95 per pack = £58.50

Therefore, buying from Value World would cost Binita £59.22 - £58.50 = £0.72 less than buying from Letters2go.

Correct Question :

The function df(x, y) = (y^2 - xy)dx - x^2 dy is an inexact differential.

To determine if a function is exact or inexact, we need to check if its partial derivatives with respect to x and y satisfy the condition ∂M/∂y = ∂N/∂x, where df(x, y) = M(x, y)dx + N(x, y)dy.

In this case, we have M(x, y) = y^2 - xy and N(x, y) = -x^2. Calculating the partial derivatives, we find:

∂M/∂y = 2y - x

∂N/∂x = -2x

Since ∂M/∂y is not equal to ∂N/∂x (2y - x ≠ -2x), the function df(x, y) = (y^2 - xy)dx - x^2 dy is inexact.

Next, we can test the integrating factor 1/(xy^2) to see if it produces an exact differential. The integrating factor is denoted by μ(x, y) and is given by μ(x, y) = e^(∫(∂M/∂y - ∂N/∂x)/N dx). If the resulting expression becomes an exact differential, the integrating factor is successful.

In this case, the integrating factor μ(x, y) = e^(∫(2y - x)/(-x^2) dx) = e^(-2y/x). However, integrating factor μ(x, y) does not produce an exact differential, and hence, it is not a suitable integrating factor for this function.

Answer:

True

Step-by-step explanation:

True. A z-score, also known as a standard score, is a statistical measure that helps to determine how far a particular value is from the mean relative to the data set's standard deviation.

A z-score is a dimensionless quantity that expresses the distance between a particular value and the mean of a distribution in terms of the number of standard deviations that the value is from the mean. A positive z-score indicates that the value is above the mean, while a negative z-score indicates that the value is below the mean.

To calculate the z-score for a given value, the formula is: z = (x - μ) / σ where z is the z-score, x is the value being considered, μ is the mean of the data set, and σ is the standard deviation of the data set.

For example, if the mean of a data set is 50 and the standard deviation is 10, and we are interested in finding the z-score for a value of 65, the calculation would be: z = (65 - 50) / 10 = 1.5. This indicates that the value of 65 is 1.5 standard deviations above the mean of the data set.

Z-scores are useful for comparing values across different data sets or for identifying extreme values in a data set. Values with high positive or negative z-scores are typically considered to be outliers, indicating that they are further from the mean than most other values in the data set.

In summary, the statement "z-score helps to determine how far a particular value is from the mean relative to the data set's standard deviation" is true. Z-scores are a statistical measure that help to express the distance between a particular value and the mean of a distribution in terms of the number of standard deviations that the value is from the mean.

The probability that Tom is selected as President is 1 in 10, or 0.1.

The probability of Tom being selected as President is 1 in 10, or 0.1. This is because there are 10 members in the club, and each selection is equally likely. Therefore, the chance of Tom being chosen as President is the same as any other member of the club. This means that there is a 1 in 10 chance of Tom being selected as President, or a 0.1 probability. This probability can also be expressed as a fraction: 1/10, which is the same as 0.1. To calculate the probability of any other selection, such as the Vice-President or Treasurer, the same method can be applied. The probability of any one member of the club being selected for any position is 1 in 10, or 0.1.
