Answer:

1/4

Step-by-step explanation:

Assuming the number cube is a six-faced die, you have

1 2 3 4 5 6

three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.

So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?

25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

The length of the rays (vectors) and the ratio of the lengths of the vectors are;

(a) \(\overrightarrow{AC}\) = \(\overrightarrow{AB}\) + \(\overrightarrow{BC}\), therefore, according to the segment addition postulate, the points A, B, and C, are on the same straight line

(b) Length of DF : Length of DE = 3.5 : 1

A vector is a quantity that has both magnitude and direction.

(a) The equations of the rays (vectors) \(\overrightarrow{AB}\) and \(\overrightarrow{AC}\) are;

\(\overrightarrow{AB}\) = 4·a + 5·b

\(\overrightarrow{AC}\) = 12·a + 15·b

The points A, B, and C, lie on the same straight line if we get;

\(\overrightarrow{AC}\) = \(\overrightarrow{AB}\) + \(\overrightarrow{BC}\), such that the rays \(\overrightarrow{AB}\) and \(\overrightarrow{BC}\) formed by the point B are a simple ratio with each other and with the ray \(\overrightarrow{AC}\)

The ratio of \(\overrightarrow{AC}\) to \(\overrightarrow{AB}\) = (12·a + 15·b) : (4·a + 5·b)

12·a + 15·b = 3 × (4·a + 5·b) = 3 × \(\overrightarrow{AB}\)

 \(\overrightarrow{AC}\) : \(\overrightarrow{AB}\) = 3 × \(\overrightarrow{AB}\) : \(\overrightarrow{AB}\) = 3 : 1

Similarly; \(\overrightarrow{BC}\) = (12·a + 15·b) - (4·a + 5·b) = 8·a + 10·b = 2 × (4·a + 5·b)

\(\overline{BC}\) = 2 × \(\overrightarrow{AB}\)

\(\overrightarrow{BC}\) : \(\overrightarrow{AB}\) = 2 × \(\overrightarrow{AB}\) :  \(\overrightarrow{AB}\)  = 2 : 1

Therefore, the point B is a point on  \(\overrightarrow{AC}\) that divides it into a ratio 2 : 1 and   \(\overrightarrow{AC}\) = \(\overrightarrow{AB}\) + \(\overrightarrow{BC}\) which indicates by the segment addition postulate that A, B, C, are on the same straight line or segment, \(\overrightarrow{AC}\)

(b) The length of ray \(\overrightarrow{DF}\), obtained by using the segment addition postulate is presented as follows;

\(\overrightarrow{DF}\) = \(\overrightarrow{DE}\) + \(\overrightarrow{EF}\)

\(\overrightarrow{DE}\) = 2·d + 5·e

\(\overrightarrow{EF}\) = -9·d - 22.5·e

\(\overrightarrow{DF}\) = 2·d + 5·e + (-9·d - 22.5·e) = -7·d - 17.5·e

Length of DF = √((-7)² + (-17.5)²) = 3.5·√(29)

Length of DE = √(2² + 5²) = √(29)

Length of DE : Length of DF = 3.5 : 1 = 7 : 2

To rewrite the expression $3x^2 + 14x + 8$ in the form $(3x + a)(x + b)$, we need to find integers $a$ and $b$ such that the product of these two terms gives the original expression.

First, we need to find the factors of $3 \times 8 = 24$. The pairs of factors are: $(1, 24), (2, 12), (3, 8), (4, 6)$. We need a pair that has a sum of $14$ (the coefficient of the middle term). The pair $(2, 12)$ meets this requirement.

Now we can write the expression as:

$(3x^2 + 2x) + (12x + 8) = (3x + 2)(x + 4)$

So, $a = 2$ and $b = 4$. The value of $a - b$ is $2 - 4 = -2$.

The correct answer is A. 0. As diversification increases, the total variance of a portfolio approaches zero.

As diversification increases, the total variance of a portfolio approaches 0, which means that the portfolio becomes less risky. This occurs because diversification spreads the risk across multiple assets, reducing the impact of any single asset on the portfolio's overall performance. The reduction in risk is due to the fact that some assets in the portfolio may perform well while others may not, but the negative performance of some assets is compensated by the positive performance of others, leading to a lower overall portfolio variance. Therefore, option A is the correct answer.

Diversification is an investment strategy that involves spreading an investor's portfolio across different assets, such as stocks, bonds, real estate, and commodities, with the aim of reducing overall risk.

Answer:

\(b. -2.5, -\frac{5}{4}, -\frac{2}{3}, 0.75, \sqrt{3}, 1.9, I-4I\)

Step-by-step explanation:

-5/4 is smaller than -2/3 since on the negative sides, any number who is larger is smaller.

0.75 is smaller than the square root of 3 since that equals to 1.7.

1.9 is smaller than the absolute value of -4 since that equals to 4.

Answer:

B) -2.5, -5/4, -2/3, 0.75, √3 (square root of 3), 1.9, |-4|

Step-by-step explanation:

The square root of 3 is ≈ 1.7, -5/4=-1.25, -2/3=-0.66..., and you have |-4|(absolute value of four)=4. So if you just transition values that are squared, fractions, etc to numbers that are easier to use, it makes it much easier to list them from least to greatest or greatest to least. You would list the negatives first, then positives. I hope this helps you and good luck with your assignment.

only option (c) satisfies the criteria of a probability distribution.

Among the options given, only (c) represents a probability distribution. A probability distribution is a function that assigns probabilities to each possible value of a random variable, ensuring that the probabilities sum to 1. In option (c), the random variable Z takes values 1, 2, 3, 4, and 5, and the corresponding probabilities assigned to these values are 0.1, 0.2, 0.3, 0.4, and 0.0, respectively. These probabilities satisfy the requirement that they sum to 1, making it a valid probability distribution.

In option (a), the random variable X has repeated values, which violates the requirement that each value should have a unique probability. For example, X takes the value 2 with a probability of 0.1 twice, which is not a valid probability distribution.

In option (b), the probabilities assigned to the values of the random variable Y are not non-negative, as there is a negative probability (-1.25). Negative probabilities are not allowed in probability distributions.

To determine if a difference exists in a psychologist's income as a function of residential status (urban vs. rural), the demographer can use the Independent Samples t-test.

The Independent Samples t-test is appropriate when comparing the means of two independent groups. In this case, the demographer has two independent samples: one from psychologists in urban areas and another from psychologists in rural areas.

The test will assess whether there is a statistically significant difference between the mean incomes of psychologists in urban and rural areas. It takes into account the variability within each group and provides a p-value indicating the likelihood of obtaining the observed difference in means by chance.

By conducting an Independent Samples t-test, the demographer can determine if there is evidence to support the hypothesis that residential status has an effect on a psychologist's income.

When multiplying two polynomials, the property that is used is the Distributive property.

When we multiply two polynomials, we use the distributive property of multiplication over addition. This property states that the product of a number (or variable) and a sum is equal to the sum of the products of the number (or variable) and each term in the sum.

In the case of polynomial multiplication, we use this property repeatedly to multiply each term in one polynomial by each term in the other polynomial. We start by multiplying the first term in one polynomial by each term in the other polynomial, then we move on to the second term in the first polynomial and multiply it by each term in the second polynomial, and so on until we have multiplied each term in one polynomial by each term in the other polynomial.

This process of multiplying each term in one polynomial by each term in the other polynomial requires the distributive property of multiplication over addition, which is why it is the property used when multiplying two polynomials. The commutative and associative properties are also useful when simplifying polynomial expressions, but they are not directly involved in polynomial multiplication.

To maximize profits, the firm should produce a quantity of goods x = 5 and y = 10, based on the cost function and price constraints.

To maximize profits, the firm needs to find the quantities of goods x and y that will yield the highest profit. The profit function can be defined as the revenue minus the cost. Revenue is calculated by multiplying the quantity of each good produced with their respective prices, while the cost function is given as C(x, y) = 10x + xy + 10y.

The firm is committed to delivering a total of 15 units, which can be expressed as x + y = 15. To determine the optimal production quantities, we need to maximize the profit function subject to this constraint.

By substituting the price expressions Ps = 50 - x + y and Py = 50 - x + y into the profit function, we obtain the profit equation. To find the maximum profit, we can take the partial derivatives of the profit equation with respect to x and y, set them equal to zero, and solve the resulting system of equations.

Solving the equations, we find that the optimal production quantities are x = 5 and y = 10, which maximize the firm's profits.
