Step-by-step explanation:

Wind speeds, represented by random variable X, have a lognormal distribution. The corresponding value of the standard normal random variable (Z) is associated with a wind speed of 14.35 is 25.5

Wind speeds represented by random variable X, in miles per hour, have a lognormal distribution. In other words, log(X) is normal.

If \(\mu = 4.8\) and \(\sigma = 0.4\), what value of Z (the standard normal rv) is associated with a wind speed of 15 miles per hour.

The value of Z (the standard normal rv) associated with a wind speed of 15 miles per hour.

The standard score (z) of a random variable X is calculated as follows:

\(z = \frac{(X - \mu)}{\sigma}\)

Given: μ = 4.8, σ = 0.4

Let X be a wind speed 15 mph.

To find the standard normal rv Z associated with a wind speed of 15 miles per hour, we will use the formula for calculating the standard score (z):

\(z = (X - \mu) /\sigma \\z = (15 - 4.8) / 0.4\\z = 25.5\)

Therefore, the value of Z (the standard normal rv) associated with a wind speed of 15 miles per hour is 25.5.

None of them.To determine which case provides the biggest torque about the rotation axis, we need to consider the factors that affect torque.

Torque is calculated as the product of the magnitude of the applied force and the perpendicular distance from the force to the rotation axis. In other words, torque = force * lever arm.

Given that the magnitude of the applied force is the same for all cases, we only need to consider the lever arm or the perpendicular distance.

Among the options provided (F1, F2, F3, F4), the case with the biggest torque will be the one with the largest lever arm or the greatest perpendicular distance from the fraction force to the rotation axis.

we cannot determine which one has the largest lever arm or the biggest torque.

No, there is no commutative property of subtraction for rational numbers. The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers.

The commutative property states that the order of the operands does not affect the result of an operation. For addition and multiplication, the commutative property holds true. However, for subtraction, the order of the operands does matter, and thus, the commutative property does not apply.

Let's consider an example to demonstrate this:

Take the rational numbers 3/4 and 1/2.

If we subtract 3/4 from 1/2, we have: 1/2 - 3/4 = (2/4) - (3/4)

= -1/4.

If we subtract 1/2 from 3/4, we have: 3/4 - 1/2 = (3/4) - (2/4)

= 1/4.

As you can see, the results are different when the order of subtraction is changed, indicating that subtraction does not follow the commutative property for rational numbers.

The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers. Changing the order of subtraction changes the result, making subtraction non-commutative for rational numbers.

The commutative property does not apply to the operation of subtraction with rational numbers. This is because changing the order of the numbers in a subtraction operation will give a different result.

In mathematics, the commutative property refers to the idea that the order in which numbers are used in an operation does not change the result of that operation. This property holds true for addition and multiplication but, unfortunately, it does not hold true for subtraction and division. For example, in subtraction, if we take two rational numbers such as 5 and 3, 5 - 3 is equal to 2, but 3 - 5 equals to -2. As you can see, changing the order of the numbers gives us different results, demonstrating that there is no commutative property of subtraction for rational numbers.

Work Shown:

r = 6 = radius

V = volume of a sphere of radius r

V = (4/3)*pi*r^3

V = (4/3)*pi*6^3

V = 904.77868423386

V = 904.8

I used my calculator's stored version of pi (instead of something like pi = 3.14)

The units "cubic meters" can be abbreviated to m^3 or \(m^3\)

The volume of the given sphere is 904.8 cubic meters. Thus, option B is the answer.

         The volume of a sphere can be calculated using the formula:

V = \(4/3 * \pi * r^3\),

Where V is the volume and r is the radius of the sphere.

\(\pi\) = 3.14

The radius of the sphere (r) = 6m

Plugging in the given radius of 6m into the formula, we get:

V = (4/3) * \(\pi\) * (6^3)

V = 1.333 * \(\pi\) * 216

V = 1.333 * 3.14 * 216

V = 4.1866 * 216

V = 904.8 cubic meters

Therefore, when the radius of the sphere is 6m, the volume of the sphere is 904.8  cubic meters.

since it is in the same line as DE, both have the same slope.

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

x changes by +4 (from 8 to 12).

y changes by -8 (from 32 to 24).

The rate at which the money is growing is exponential. The formula for determining such exponential growth is expressed as

A(t) = Pe^rt

Where

A(t) represents the amount after t years

P represents the initial amount

t represents the number of years

r represents the growth rate

Given that the amount doubles after 6 years, it means that

when t = 6, A(t) = 7400 * 2 = 14800

Recall, P = 7400

Thus, the expression becomes

14800 = 7400e^6t

14800/7400 = e^6t

2 = e^6t

Taking natural logarithm of both sides of the equation, it becomes

ln 2 = ln e^6t = 6t lne

Recall, ln e = 1

Thus, we have

ln 2 = 6t

t = ln2/6 = 0.1155

The equation would be

A(t) = 7400e^0.1155t

When t = 4, it becomes

A(t) = 7400e^0.1155*4

A(t) = 11745.62

Rounding to the nearest dollar, the amount in the account after 4 years is

The expression (a×10^3)(b×10^−2) / (c×10^5)(d×10^−3) can be simplified to a numerical value using the given values for a, b, c, and d.

Substituting the given values a=6.01, b=5.07, c=7.51, and d=5.64 into the expression, we get:

(6.01×10^3)(5.07×10^−2) / (7.51×10^5)(5.64×10^−3)

​

To simplify this expression, we can combine the powers of 10 and perform the arithmetic operation:

(6.01×5.07)×(10^3×10^−2) / (7.51×5.64)×(10^5×10^−3)

=30.4707×(10^3−2)×(10^5−3)

A discrete probability distribution is a statistical distribution that relates to a set of outcomes that can take on a countable number of values, whereas a continuous probability distribution is one that can take on any value within a given range.Therefore, the main difference between the two types of distributions is the type of outcomes that they apply to.

An example of a discrete probability distribution is the probability of getting a particular number when a dice is rolled. The possible outcomes are only the numbers one through six, and each outcome has an equal probability of 1/6. Another example is the probability of getting a certain number of heads when a coin is flipped several times.

On the other hand, an example of a continuous probability distribution is the distribution of heights of students in a school. Here, the range of heights is continuous, and it can take on any value within a given range.

The expected value of a probability distribution measures the central tendency or average of the distribution. In other words, it is the long-term average of the outcome that would be observed if the experiment was repeated many times.

For a discrete probability distribution, the expected value is computed by multiplying each outcome by its probability and then adding the results. In mathematical terms, this can be written as E(x) = Σ(xP(x)), where E(x) is the expected value, x is the possible outcome, and P(x) is the probability of that outcome.

For example, consider the probability distribution of the number of heads when a coin is flipped three times. The possible outcomes are 0, 1, 2, and 3 heads, with probabilities of 1/8, 3/8, 3/8, and 1/8, respectively. The expected value can be computed as E(x) = (0*1/8) + (1*3/8) + (2*3/8) + (3*1/8) = 1.5.

Therefore, the expected value of the distribution is 1.5, which means that if the experiment of flipping a coin three times is repeated many times, the long-term average number of heads observed will be 1.5.

The probability that Marta makes at least 2 of the 3 free throws is 0.972

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

Proportion of throws = 90%

Number of throws = 3

The probability that Marta makes at least 2 of the 3 free throws is calculated as

Probability = P(2) + P(3)

Each individual probability can be calculated using

P(x) = nCx * p^x * (1 - p)^(n - x)

Substitute the known values in the above equation, so, we have the following representation

Probability = 3C2 * (0.9)^2 * (1 - 0.9)^1 + 3C3 * (0.9)^3 * (1 - 0.9)^0

Evaluate the expressions

Probability = 0.243 + 0.729

So, we have

Vertical asymptote occurs at when f(x) = 0 where;

f(x) is the denominator of the given function.

From the expression given: f(x) = x

Since f(x) => 0, hence x = 0

To get the horizontal asymptote, we will look at the degree of the numerator and denominator. If the degree of numerator is less than the denominator, the horizontal asymptote will be zero. From the function, we can see that the degree of the numerator is zero (being a constant) and that of the denominator is 1.

Since the number 18 remains constant regardless of the change in number of weeks, we know that at the start h (w=0) = 18 + 2.5 x 0.

This means that, when Jin planted the sunflower, the sunflower's height was already 18 inches.

For such a reason, we can conclude that the number 18 could represent the sunflower's height at the start (original height).
