Step-by-step explanation:

We want to isolate the 'y' variable, so we will subtract 7 from both sides.

y = x + 6 - 7

y = x -1

The value of linear function represents the line given by the point-slope equation y + 7 = (x + 6) is,

⇒ y = x - 1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

the point-slope equation is,

y + 7=(x + 6)

Hence, We get;

y + 7=(x + 6)

y = x + 6 - 7

y = x - 1

Thus, The value of linear function represents the line given by the point-slope equation y + 7 = (x + 6) is,

⇒ y = x - 1

The probability that either event A or event B will occur is 2/3.

The probability that either event A or event B will occur can be calculated using the formula P(A or B) = P(A) + P(B) - P(A and B). This formula accounts for the possibility of both events A and B occurring simultaneously.

When we add the probabilities of event A and event B individually (P(A) + P(B)), we are counting the cases where both events occur twice. To avoid this double counting, we subtract the probability of both events occurring together (P(A and B)).

This can be understood through a simple example. Let's say we have two events: event A is rolling an even number on a fair six-sided die, and event B is rolling a number less than 4 on the same die.

The probability of event A occurring is P(A) = 3/6 = 1/2 (since three out of six numbers are even).

The probability of event B occurring is P(B) = 3/6 = 1/2 (since three out of six numbers are less than 4).

If we simply add P(A) + P(B) without accounting for the possibility of both events occurring together, we would get 1/2 + 1/2 = 1, which is incorrect. The correct probability should be less than 1 since events A and B are not mutually exclusive.

To calculate the correct probability, we need to determine the probability of both events occurring together, which is the probability of rolling an even number less than 4. In this case, the probability of event A and event B occurring simultaneously is P(A and B) = 1/6 (since only the number 2 satisfies both conditions).

Using the formula P(A or B) = P(A) + P(B) - P(A and B), we have P(A or B) = 1/2 + 1/2 - 1/6 = 2/3.

Therefore, the probability that either event A or event B will occur is 2/3, not simply the sum of the individual probabilities.

Answer:

Quantity of soap left after Juan washes 8 regular loads and 5 heavy loads of laundry [tex]=12.9[/tex] pounds.

Step-by-step explanation:

Number of scoop of soap used to wash a regular load of laundry = One 0.15 pound scoop

Number of scoops of soap used to wash heavy work clothes = Two 0.15 pound scoops

The probability that a customer will not have to wait upon arriving at the automatic teller machine is 0.78 (rounded to 2 decimal points).

To compute the probability that a customer will not have to wait upon arriving at the automatic teller machine, we need to determine the arrival rate and the service rate.

Customers arrive at a rate of one every other minute. This means the arrival rate (λ) is 1 customer per 2 minutes, or λ = 1/2 customers per minute.

Each customer spends an average of 90 seconds completing their transaction. This means the service rate (μ) is 1 customer per 90 seconds, or μ = 1/90 customers per second.

To calculate the probability that a customer will not have to wait, we can use the M/M/1 queueing model, where M represents the exponential distribution for both arrivals and service.

The formula for the probability that the system is in the empty state (no customers in the system) is given by:

P0 = 1 - (λ/μ)

Substituting the values:

P0 = 1 - (1/2) / (1/90)

P0 = 1 - (45/2)

P0 = 1 - 22.5

P0 = 0.775

Therefore, the probability that a customer will not have to wait upon arriving at the automatic teller machine is 0.78 (rounded to 2 decimal points).

The row space of a matrix A is the subspace spanned by the row vectors of A. It represents all possible linear combinations of the row vectors of A. The matrix A is the subspace spanned by the column vectors of A.

To find a basis for the row space of matrix A, we can perform row operations to reduce the matrix to row-echelon form. The nonzero rows of the row-echelon form of A will form a basis for the row space of A. These row vectors are not necessarily the same as the row vectors of A.

To find a basis for the row space of A that are row vectors of A, we can observe the nonzero rows of the original matrix A itself. These row vectors, without any row operations, will form a basis for the row space of A.

In the case of matrix A = [1 2 -1; 3 -8 7; -2 5 -3], we need to perform row operations to reduce the matrix to row-echelon form and identify the nonzero rows. The resulting nonzero rows will form the basis for the row space of A.

Answer:

  T/V = P/(nR)

Step-by-step explanation:

You want to find T/V from the equation PV = nRT.

T is in the numerator of the ratio you want. V is on the other side of the equation from T, so you can put V in the denominator by dividing both sides of the equation by V:

  [tex]P=\dfrac{nRT}{V}[/tex]

Now, you can get the ratio T/V by itself by dividing by its coefficient:

  [tex]\dfrac{P}{nR}=\dfrac{T}{V}[/tex]

Swapping sides gives you the relation you want:

Company A will charge more than Company B for mileages greater than 70/(0.60 - 0.80) = 350 miles.

To determine the mileages for which Company A charges more than Company B, we need to compare the cost functions of the two companies. Let C_A(m) represent the cost for Company A and C_B(m) represent the cost for Company B.

For Company A, the cost function is C_A(m) = 0.80m, as there is no initial fee and they charge 80 cents per mile driven.

For Company B, the cost function is C_B(m) = 70 + 0.60m, as there is an initial fee of $70 and an additional 60 cents per mile driven.

To find the mileage at which Company A charges more than Company B, we set the two cost functions equal to each other and solve for m:

0.80m = 70 + 0.60m

0.80m - 0.60m = 70

0.20m = 70

m = 70 / 0.20

m = 350

Therefore, for mileages greater than 350 miles, Company A will charge more than Company B.

Gross Profit Margin (GPM) is a metric used to calculate the percentage of gross profit earned by a business on its sales. The gross profit is calculated as revenue minus cost of goods sold (COGS), and the formula for gross profit margin is:(Gross Profit ÷ Revenue) x 100%.

The gross profit margin reveals the percentage of sales that turn into gross profit. A company with a higher gross profit margin has a better chance of generating a good profit than one with a lower gross profit margin. The gross profit margin formula allows companies to determine how much revenue is remaining to cover operating expenses and net profit. In computing gross profit margin, the following steps should be taken:

First, calculate gross profit as follows: Revenue - Cost of Goods Sold (COGS) = Gross Profit.

Then, use this formula to compute gross profit margin: Gross Profit ÷ Revenue x 100%.

The gross profit margin is an important ratio used to assess a company's profitability. It is important because it reflects the percentage of sales that contribute to covering operating expenses and generating net profits. A higher gross profit margin ratio indicates that a company is earning enough on sales to cover its operating expenses and generate profits.However, one of the major drawbacks of using gross profit margin as a profitability metric is that it does not account for operating expenses. This is why it is important to calculate other profitability metrics, such as operating profit margin, to gain a complete picture of a company's profitability.It is also important to compare gross profit margins over time and with industry averages to determine how a company is performing relative to its peers. A declining gross profit margin may indicate increasing costs, pricing pressures, or a shift in product mix. Conversely, an increasing gross profit margin may suggest that the company has a competitive advantage, pricing power, or is reducing its costs.

In summary, the gross profit margin measures the percentage of revenue that contributes to gross profit. A higher gross profit margin indicates that a company is earning enough on sales to cover its operating expenses and generate profits. However, it is important to compare gross profit margins over time and with industry averages to determine how a company is performing relative to its peers. Finally, it is important to use other profitability metrics, such as operating profit margin, to gain a complete picture of a company's profitability.
