The given statement about two variables is false. This is because to determine whether the respective two variables are related, we cannot compare two marginal distributions.

A correlation coefficient is used to assess the relationship between the two variables. The letter r is used to represent this coefficient. The r values range from -1 to  +1.

Based on this value, the correlation is classified into two types negative correlation and positive correlation. When the r value is -1, it is referred to as a perfect negative correlation. When the r value is +1, it is referred to as a perfect positive correlation. So to compare the relation of two variables, we require a correlation coefficient, not marginal distribution. Therefore, the given statement is false.

Yes we can say that 10 mm is a conversion factor because it is equals to 1 cm and that is what conversion factor is.

A millimetre is a unit of measurement smaller than a metre. Because of something called conversion factors, I know that a mm is smaller than a m.

Simply said, a conversion factor is a number that may be multiplied or divided to convert one set of units to another. Hence, when we need to translate 10 millimetres to centimetres, we utilise a conversion factor.

The mm to m conversion factor is:

10 mm = 1 cm

We can simply compute the conversion of 10 mm to m now that we know the conversion factor by multiplying 0.001 by the amount of millimetres we have, which is 10.

The volume occupied by the lower square part of the shed is 4800 cubic ft.

A measurement of three-dimensional space is volume. Several imperial or US customary units, as well as SI-derived units (such the cubic metre and litre), are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship. The volume of a container is typically thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the amount of fluid (liquid or gas) that the container may hold.

The volume of the lower part of the shed is given as:

V = (l)(w)(h)

where, l is the length = 20 ft.

w is the width = 20 ft

h is the height = 12 ft

Substituting the value we have:

V = (20)(20)(12)

V = 4800 cubic ft.

Hence, the volume occupied by the lower square part of the shed is 4800 cubic ft.

Answer:

[tex](u \circ \; w)(2) = \boxed{7}[/tex]

[tex](w \circ \;u)(2) = \boxed{3}[/tex]

Step-by-step explanation:

We have the two functions as

[tex]u(x) = x^2 + 3\\\\w(x) = \sqrt{x + 2}[/tex]

[tex](u \circ w)(x)[/tex] also written as [tex]u(w(x))[/tex]  is the composite function;  it means that
[tex]x = w(x)[/tex] should be substituted in [tex]u(x)[/tex]

To determine [tex](u \circ w)(x)[/tex], simply substitute the expression for [tex]w(x)[/tex] wherever there is an x in [tex]u(x)[/tex]

For a specific value of x, in this case x = 2,

Part 1
[tex](u \circ w)(2):\\\\w(2) = \sqrt{2 + 2} = 4(u \circ w)(2) = 2^2 + 3 = 4 + 3 = 7[/tex]

For [tex](w \circ u)(x),[/tex] we substitute the expression for [tex]u(x)[/tex] into [tex]w(x)[/tex] wherever an [tex]x[/tex] appears in [tex]w(x)[/tex]

For a specific value of x, say 2, find the value of u(2) and substitute it into [tex]w(x)[/tex]

[tex]u(2) = 2^2 + 3 = 7[/tex]

[tex](w \circ u)(2), = \sqrt{7 + 2} = \sqrt{9} = 3\\[/tex]

Diane's monthly payment for borrowing $3,000 at 13.5% APR over 36 months is $101.81.

We can use an online finance calculator to compute the monthly payment, setting the following parameters.

The monthly payment shows the periodic payment that must be made to settle the loan with the finance charges.

N (# of periods) = 36 months

I/Y (Interest per year) = 13.5%

PV (Present Value) = $3,000

FV (Future Value) = $0

Results:

Monthly payments (PMT) = $-101.81

Dot plot 2, on the other hand, is skewed and does not have a symmetrical distribution, which may not be a good representation of the sample means.

What is normal distribution ?

Normal distribution is a statistical concept that describes a symmetrical, bell-shaped curve that is characterized by its mean and standard deviation. It is a continuous probability distribution that represents the probability of a random variable taking on a certain value.

As per the Central Limit Theorem, the sample means of a sufficiently large sample size taken from any population tend to follow a normal distribution, regardless of the shape of the population distribution. Therefore, the dot plot that is likely to represent the means of the samples of size 10 from this population is dot plot 1 because it has a more symmetrical distribution, which is more similar to a normal distribution.

Hence, Dot plot 2, on the other hand, is skewed and does not have a symmetrical distribution, which may not be a good representation of the sample means.

If the cross-price elasticity of demand for two goods is 1.25, then the two goods are substitutes.

Cross Price Elasticity of Demand:

The cross elasticity of demand is an economic concept that measures the response of the quantity demanded of one good to changes in the price of another good. Also known as the cross-price elasticity of demand, this measure is calculated by dividing the percentage change in quantity demanded for one good by the percentage change in price of another commodity.

[tex]E_X_Y[/tex] = [tex]\frac{Percentage change in Quantity of X }{Percentage Change in Quantity of Y}[/tex]

[tex]E_X_Y[/tex] = ΔQ/Q ÷ ΔP/P

       = ΔQ/Q × P/ΔP

       = ΔQ/ΔP × P/Q

where:

Q = Quantity of good X

P = Price of good Y

Δ = Change

​The cross elasticity of demand for a substitute is always positive because an increase in the price of a substitute increases the demand for one good. For example, when the price of coffee rises, the demand for tea (alternative beverage) increases as consumers switch to cheaper but alternative beverages. This is reflected in the formula for the cross-elasticity of demand, as the numerator (the percentage change in demand for tea) and the denominator (the price of coffee) represent positive increases.

Items with a coefficient of 0 are unrelated and independent products. Commodities can be weak substitutes for which both products are positive but have a low cross-elasticity of demand. This is often the case with various alternative products such as tea or coffee. Commodities that are strong substitutes have a higher cross-elasticity of demand. Consider a different brand of tea. An increase in the price of green tea from one company has a greater impact on the demand for green tea from the other company.

The cross elasticity of demand is 1.25. Positive cross elasticity means that when the price of one good changes, the quantity demanded of another good changes in the same direction. For example, when the price of one good increases, the demand for another good increases.

This indicates that the two products are fungible. When the price of a product rises, consumers will prefer the cheaper product. As a result, the demand for alternatives will increase.

The critical value, zα/2, that corresponds to a 87% confidence level is approximately 1.514.

The critical value, zα/2, is the z-score that cuts off an area of α/2 in the tails of the standard normal distribution. In other words, it represents the number of standard deviations away from the mean that corresponds to a particular level of confidence.

To find the critical value for a 87% confidence level, we first need to determine the area that is left in the tails of the distribution. Since the confidence level is 87%, the area in the middle of the distribution is (1 - 0.87) = 0.13. We then divide this area in half to get the area in each tail, which is 0.065.

Using a standard normal distribution table or a calculator, we can find that the z-score that cuts off an area of 0.065 in one tail is approximately 1.514. Therefore, the critical value, zα/2, is:

zα/2 = ±1.514

However, since we want to find the z-score that corresponds to the middle 87% of the distribution, we need to add the absolute value of this number to the mean of the distribution, which is 0. This gives us:

zα/2 = |1.514| = 1.514

Therefore, the critical value, zα/2, that corresponds to a 87% confidence level is approximately 1.514
