Multiplication is the process of multiplying. The products that have the same sign as the product of -2 3/7 and -6/11 are B and D.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The product of two positive numbers and the product of two negative numbers both are positive while the product of a negative number and a positive number is negative. Therefore, the product of -2 3/7 and -6/11 is positive, since both are negative.

A.) 3/8 × (-6/7) = Negative

B.) 1 2/9 × 2 6/17 = Positive

C.) -9/20 × 3 4/5 = Negative

D.) -1/3 × -2/3 = Positive

Hence, the products that have the same sign as the product of -2 3/7 and -6/11 are B and D.

It is discovered that there is a 0.3934, or 39.34%. likelihood that a customer waits fewer than 30 seconds using the exponential distribution.

The following equation describes an exponential probability distribution with mean m:

f(x) = μe∧(- μe)

The decay parameter is in the following:

μ = 1/m

When x is less than or equal to a, the probability is given by:

P(X ≤ x) = ∫ f(x) dx (limits 0 → a)\

which can be resolved as follows:

P(X ≤ x) = 1 - e∧(- μe)

Since 60 seconds is the mean in this problem, then decay parameter is:

μ = 1/60

The likelihood that a customer will wait under 39 seconds is:

P(X ≤ 30) = 1 - e∧(- 30/60)

P(X ≤ 30) = 0.3934

Thus, the probability that a consumer will wait less than 30 seconds is 0.3934, or 39.34%.

To calculate Elizabeth's finance charge using the previous balance method, we need to determine the average daily balance and then apply the APR (Annual Percentage Rate) to calculate the finance charge.

First, let's calculate the average daily balance:

Beginning Balance: $969.26

Days until payment: 2 (from July 1st to July 3rd)

Payment: $45.00

Days until purchase: 7 (from July 3rd to July 10th)

Purchase: $67.48

Days until payment: 2 (from July 10th to July 12th)

Payment: $20.00

Days until payment: 16 (from July 12th to July 28th)

Payment: $85.00

To calculate the average daily balance, we sum up the balances for each day and divide it by the total number of days in the billing cycle (30 days).

Average Daily Balance = (969.26 × 2 + 0 × 7 + 67.48 × 2 + 0 × 16) / 30 = $85.95

Next, we can calculate the finance charge using the APR:

Finance Charge = Average Daily Balance × (APR / 365) × Number of Days in the Billing Cycle

Finance Charge = 85.95 × (0.1461 / 365) × 30 ≈ $9.97

Therefore, Elizabeth's July finance charge will be approximately $9.97. The correct answer is option a.

We need an approximate sample size of n = 122 to estimate the population means the age of the incoming fall term transfer students, with a population standard deviation of 5.4, a margin of error of 2.3, and a confidence level of 99%. Therefore, the answer is 122.

The formula for calculating the sample size, given the population standard deviation, the desired level of confidence, and the margin of error, is as follows:

n = (zα/2)² * σ² / E²

Where, α is the significance level, zα/2 is the z-score at the α/2 percentile of the standard normal distribution, σ is the population standard deviation, E is the margin of error

To calculate the sample size required to estimate the population means age of the incoming fall term transfer students, with a population standard deviation of 5.4, a margin of error of 2.3, and a confidence level of 99%, we can substitute these values in the formula:n = (zα/2)² x σ² / E²

Where α = 0.01 (since we want a 99% confidence level, we need to subtract 1 from 100 and convert it to a decimal)

E = 2.3σ = 5.4

Using a z-table or a calculator, we can find the z-score at the 0.005 level of the standard normal distribution. The z-score is approximately 2.576.

n = (2.576)² * (5.4)² / (2.3)²

n ≈ 121.28

The reorder point for the product is 36 units.

To determine the reorder point, we need to consider the average daily sales and the average lead time.

Average daily sales: The average daily sales of the product are given as 8 units.

Average lead time: The average lead time for delivery is 4 days, with probabilities of 0.2, 0.6, and 0.2 for 3, 4, and 5 days, respectively. We can calculate the expected lead time as follows:

Expected lead time = (Probability of 3 days * 3) + (Probability of 4 days * 4) + (Probability of 5 days * 5)

Expected lead time = (0.2 * 3) + (0.6 * 4) + (0.2 * 5)

Expected lead time = 0.6 + 2.4 + 1

Expected lead time = 4 days

Reorder point calculation: The reorder point is the inventory level at which an order needs to be placed to avoid stockouts. It is determined by multiplying the average daily sales by the average lead time. In this case:

Reorder point = Average daily sales * Average lead time

Reorder point = 8 units * 4 days

Reorder point = 32 units

Therefore, the reorder point for the product is 32 units.

The provided random numbers (sets 1 and 2) are not used in the calculation of the reorder point. They might be relevant for other parts of the problem or for future analysis, but they are not necessary for determining the reorder point in this case.

Additional comment

When in doubt, you can use your calculator to evaluate these expressions. If the decimal fraction uses all available digits, the number is likely irrational.

If the number cannot be expressed exactly without using symbols (√, ∛, π, e), then it is irrational. The attached calculator display shows this nicely.

We can confirm this by subtracting the equations, which results in 0 = 4x - 6, which has no solution.

Sylvie might have written the equation y = 4x + 1. This equation has the same slope (4) as Jason's equation, but has a different y-intercept (1, instead of 2). This means that the two equations will never intersect, as the lines will be parallel, so there will be no solution. To check this, we can subtract equations: y - (4x + 1) = 5 - 4x - 1. Simplifying, we get 0 = 4x - 6, which has no solution. This confirms that the two equations have no solution.

The distribution factor for members CC1 and CC2 in the given frame is 0.27.

To find the distribution factor for members CC1 and CC2 in the given frame, we need to use the principle of virtual work or the method of consistent deformations.

Since member CD has a distribution factor of 0.21, it means that when a unit load is applied at joint C, member CD carries 0.21 units of that load. Similarly, member CF carries 0.25 units of the load applied at joint C.

Since members CC1 and CC2 are equal, we can assume that they carry an equal proportion of the load applied at joint C. Let's denote the distribution factor for members CC1 and CC2 as x. Therefore, the load carried by member CC1 would be x units, and the load carried by member CC2 would also be x units.

According to the principle of equilibrium, the total load applied at joint C should be equal to the sum of the loads carried by each member connected to it. In this case, we have:

0.21 + 0.25 + x + x = 1

Simplifying the equation:

0.46+2x=1

Subtracting 0.46 from both sides:

2x=1−0.46

2x=0.54

Dividing both sides by 2:

x=0.27

Therefore, the distribution factor for members CC1 and CC2 in the given frame is 0.27.

An inequality that can be written in the form ax + by < c (where a and b are not both zero) is called a linear inequality in two variables.

An inequality that represents a line in a two-dimensional coordinate system is referred to as a linear inequality. The set of points that satisfies the inequality is a half-plane bounded by a line that may be dashed or solid.

In contrast to a linear equation, which represents a line, a linear inequality represents a half-plane. The points on one side of the line, rather than the points on the line, are solutions to the inequality.

The method of shading is used to graph a linear inequality in two variables. First, graph the boundary line, which is usually represented by a solid or dashed line, and then select a test point on one side of the line. Shaded regions of the half-plane containing the test point satisfy the inequality.

In mathematics, an algebraic expression is one that was created using integer constants, variables, and algebraic operations

The amount spent on a new house exists $ 810,000.

Using letters or alphabets to represent numbers without giving their exact quantities is the idea behind algebraic expressions. In mathematics, an algebraic expression is one that was created using integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by an exponent that is a rational number).

If n 5, the roots of a degree n polynomial expression, or the solutions of a degree n polynomial equation, may always be expressed as algebraic expressions.

An algebraic solution is what we refer to as a solution to an equation. But if n is greater than five, the Abel-Ruffini theorem asserts that only certain of these equations have algebraic solutions.

Abby spent 1/6 of the lottery on a new car

and 3/4 of the lottery on a new house

Total expenditure = $990,000

a. Let w be the lottery winnings,

then, 1/6 x w + 3/4 x w = $990,000

b. ⇒ w/6 + 3w/4 = $990,000

simplifying the above equation, we get

⇒ (2w + 9w)/12 = $990,000

⇒ 11w = 12 x $990,000

⇒ w = 12 x $990,000/11

⇒ w = 12 x 90,000

⇒ w = $1,080,000

The Taylor polynomial t1(x) for the function f(x) = cos(x) based at b = 6 is t1(x) = 1 - 2(x - 6).

The Taylor polynomial of degree 1, denoted as t1(x), is a polynomial approximation of a function based on its derivatives at a particular point. In this case, we are finding t1(x) for the function f(x) = cos(x) based at b = 6.

To find t1(x), we need to consider the first-degree terms of the Taylor series expansion. The first-degree term is given by f(b) + f'(b)(x - b), where f(b) represents the function value at b and f'(b) represents the derivative of the function evaluated at b.

For the function f(x) = cos(x), we have f(b) = cos(6) and f'(b) = -sin(6). Substituting these values into the first-degree term formula, we obtain t1(x) = cos(6) - sin(6)(x - 6). Simplifying further, we get t1(x) = 1 - 2(x - 6).

In summary, the Taylor polynomial t1(x) for the function f(x) = cos(x) based at b = 6 is given by t1(x) = 1 - 2(x - 6). This polynomial provides a linear approximation of the function f(x) near the point x = 6.
