CONCLUSION:

The sampling distribution model for figuring out how many people in this group might not pay on time is:

E. mean = 8%; standard deviation = 1.1%.

The steps to determine the mean and standard deviation of the sampling distribution of the proportion of clients who may not make timely payments would be:

Start with the idea that 8% of the loans will have payments that are late. So the percentage of people who pay late is p = 0.08.

Calculate the sample size, which is given as n = 600.

Determine the mean of the sampling distribution. The mean of the sampling distribution of the proportion of late payments is equal to the population proportion, which is 0.08.

Find the standard deviation of the distribution of the samples. The standard deviation is discovered by taking the square root of the commodity of the sample size and the percentage of late payments in the whole population (1 - percentage of late payments in the whole population) and dividing it by the sample size:

σ = √( (p * (1-p)) / n )

σ = √( (0.08 * 0.92) / 600 ) ≈ 0.011

So, the answer will be option E. mean = 8%; standard deviation = 1.1%.

There are four levels of measurements in a grouped frequency distribution table - ordinal ,interval ,nominal, ratio.

What is a frequency distribution ?

A frequency table is a type of table used to represent the different frequencies from a collection of data.

In order to create a frequency table, you must first look at your data and create suitable groups. Your group size may depend on the number of variables you have. Once you have grouped your data you can tally the number of times each variable occurs to find out the frequency.

There are two types of frequency tables; grouped data and ungrouped data frequency tables.

A grouped frequency table (grouped frequency distribution) is a way of organising a large set of data into more manageable groups.

The level of measurement tells you how data is recorded. There are four different levels of measurements used in statistics:

1. Nominal-The nominal level of measurement is data that can be categorised but the data has no order.

Eg - Place of birth, eye colour, gender.

2. Ordinal- The ordinal level of measurement is data that can be categorised and ordered. Although there is an order between the data, you cannot see the intervals between each variable.

For eg - Satisfaction survey, top 5 goal scorers.

3. Interval- The interval level of measurement is data that can be categorised and ranked and there is a scale on which you know the difference between each of the variables.

For eg - Temperature, test scores.

4. Ratio-The ratio level of measurement gives an order to the variables, where there is a difference between the variables, as well as a true zero point.

For eg - Height, age.

Thus, there are four levels of measurements in a grouped frequency distribution table - ordinal ,interval ,nominal, ratio.

The correct answer is log(x^(x)) = x * log(x).

The logarithmic rule states that log(a^b) = b * log(a).

So, let's apply this rule to log(x^(x)):

log(x^(x)) = x * log(x)

On the right side of the equation, x represents the exponent and log(x) represents the base.

This equation states that the logarithm of x raised to the power of x is equal to x times the logarithm of x.

Now let's simplify the other options:

x * log(x) is already simplified from the equation above, so we don't need to change it.

log(x) * log(x) is simply the logarithm of x raised to the power of 2, which is not equal to the logarithm of x raised to the power of x.

log(x) is the logarithm of x with a base of 10, and log(x) log(x) does not have a valid mathematical interpretation.

The triangle PQR is an equilateral triangle

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

PQ=QR.

m/P = (2x - 26) and m/R= (x+17)

When two sides of a triangle are congruent, then the triangle is an isosceles triangle

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

2x - 26 = x + 17 --- base angles of an isosceles triangle

So, we have

x = 43

This gives

m/P = 2 * 43 - 26 = 60

m/R= 43 + 17 = 60

Answer: Let's call the number of marbles that Kayla gets x. Then, Leanne gets 3x marbles. The total number of marbles that the girls receive is x + 3x = 4x, so 4x must equal 42 marbles:

4x = 42

Dividing both sides by 4:

x = 10.5

Since the number of marbles that each girl receives must be an integer, we round down to the nearest whole number. So, Kayla gets 10 marbles and Leanne gets 3 * 10 = 30 marbles.

Step-by-step explanation:

The required point of intersection of the two lines is (-2, 7/3).

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

The equation "y = 2/3x + 3" represents a line in the coordinate plane. It has a slope of 2/3 and a y-intercept 3. The equation "x = -2" represents a vertical line. It has no slope and the x-coordinate of all its points is -2.

Since the two equations represent lines, we can find their point of intersection by setting the two equations equal to each other and solving for y.

So, we have:

2/3x + 3 = y

and

x = -2

Substituting x = -2 into the first equation, we get:

2/3(-2) + 3 = y

Solving for y:

y = -2/3 * -2 + 3 = 4/3 + 3 = 7/3

Thus, the point of intersection of the two lines is (-2, 7/3).

An observational study is used in fields such as epidemiology, social sciences, psychology, and statistics to draw conclusions from a sample to a population where the independent variable is not under the researcher's control due to ethical concerns or logistical constraints.

Observational studies involve the study of participants who have had no forced change in their circumstances, i.e., no intervention.

Although participants' behavior may change while being observed, the goal of observational studies is to look into the 'natural' state of risk factors, diseases, or outcomes.

Answer:

70

Step-by-step explanation:

Let the number we want is "x".

4200 = 60 x

4200/60 = x

x= 70

The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

The area enclosed by the curve y = -x² and y = x² - i is the difference of the areas between these two curves.

To find the area enclosed by the curve y = x², we need to find its definite integral with respect to x from -∞ to ∞.

The definite integral of y = x² with respect to x from -∞ to ∞ is:

∫[-∞,∞] x² dx = (x³/3) from -∞ to ∞

Since the definite integral of an infinite function from -∞ to ∞ is undefined, we cannot find the exact value of the area enclosed by the curve y = x².

However, we can use the definite integral of y = x² - i with respect to x from -∞ to ∞ to find the area enclosed by the curve y = x² - i:

∫[-∞,∞] (x² - i) dx = (x³/3 - i * x) from -∞ to ∞

Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.

Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:

Area enclosed by y = x² - i - Area enclosed by y = -x² = 56

The first equation, y = -x^2, is a parabola that opens downwards.

The second equation, y = x^2 - i, is also a parabola but is translated downward by i units.

The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x^2 - i.

The area under y = -x^2 can be calculated as follows:

A = ∫[-a,a] -x^2 dx = -(1/3) x^3 |^a_-a = (1/3) a^3

Where a is the x-value at which the two curves intersect.

The area under y = x^2 - i can be calculated as follows:

B = ∫[-a,a] (x^2 - i) dx = (1/3) x^3 - i x |^a_-a = (1/3) a^3 - i a

The area enclosed by the two curves is then given by:

C = B - A = (1/3) a^3 - i a - (1/3) a^3 = -i a

Since we know that the area enclosed by the curves is 56, we can set up the equation:

-i a = 56

So,

i = -56/a

Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.

Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

QUESTION CORRECTION: Find the value of i for which the area enclosed by the curve =−x² and =x²− i equal to 56.

The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

The area enclosed by the curve y = -x² and y = x² - i is the difference of the areas between these two curves.

To find the area enclosed by the curve y = x², we need to find its definite integral with respect to x from -∞ to ∞.

The definite integral of y = x² with respect to x from -∞ to ∞ is:

∫[-∞,∞] x² dx = (x³/3) from -∞ to ∞

Since the definite integral of an infinite function from -∞ to ∞ is undefined, we cannot find the exact value of the area enclosed by the curve y = x².

However, we can use the definite integral of y = x² - i with respect to x from -∞ to ∞ to find the area enclosed by the curve y = x² - i:

∫[-∞,∞] (x² - i) dx = (x³/3 - i * x) from -∞ to ∞

Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.

Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:

Area enclosed by y = x² - i - Area enclosed by y = -x² = 56

The first equation, y = -x^2, is a parabola that opens downwards.

The second equation, y = x² - i, is also a parabola but is translated downward by i units.

The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x² - i.

The area under y = -x^2 can be calculated as follows:

A = ∫[-a,a] -x²dx = -(1/3) x³ |^a_-a = (1/3) a³

Where a is the x-value at which the two curves intersect.

The area under y = x^2 - i can be calculated as follows:

B = ∫[-a,a] (x² - i) dx = (1/3) x³ - i x |^a_-a = (1/3) a³ - i a

The area enclosed by the two curves is then given by:

C = B - A = (1/3) a³ - i a - (1/3) a³ = -i a

Since we know that the area enclosed by the curves is 56, we can set up the equation:

-i × a = 56

So,

i = -56/a

Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.

Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.
