The ordered pairs A. (−6, −14) and B. (−1, −7) in the form (x, y) are solutions to the equation 7x-5x=28.

A pair is considered to be ordered when two elements are written inside parantheses and are separated by a comma. The ordered pair (x, y), for instance, is represented by the notation (x, y), where 'x' is referred to as the first element and 'y' as the second element.

Depending on the context in which they are used, these elements—which can either be variables or constants—have different names. In a pair of elements that are ordered, the elements' order is somewhat significant. This indicates that (x, y) might not always be equal to (y, x).

We have given the equation 7x – 5y = 28

we know that a ordered pair (x,y)  must satisfy the equation

So let us do trial and error method

A. (−6, −14)

7(-6) – 5(-14) = 28

-42 + 70 = 28

28 = 28

ordered pair (−6, −14) in the form (x, y) satisfy for 7x – 5y = 28

B. (−1, −7)

7(-1) – 5(-7) = 28

-7 + 35 = 28

28 = 28

ordered pair (−1, −7) in the form (x, y) satisfy for 7x – 5y = 28

C. (4, 10)

7(4) – 5(10) = 28

28 - 50= 28

22 ≠ 28

ordered pair (4, 10) in the form (x, y) doesn't satisfy for 7x – 5y = 28

D. (7, 9)

7(7) – 5(9) = 28

49 - 45= 28

4 ≠ 28

ordered pair (7, 9) in the form (x, y) doesn't satisfy for 7x – 5y = 28

Thus, the ordered pairs A. (−6, −14) and B. (−1, −7) in the form (x, y) are solutions to the equation 7x-5x=28.

Answer:

e=32, f=79, d=69

Step-by-step explanation:

32 and e are vertical angles, so they share the same value. Same with 69 and d. 69+e+f=180, so process of elimination gives you your answer. Lmk if you need any more help or a better explanation, hope you get ungrounded !

Answer:

f = 79 , e = 32 , d = 69

Step-by-step explanation:

32 + 69 + f = 180

The accumulated value of the annuity, considering quarterly payments of $575 for 17 years with a nominal interest rate of 13% per year compounded quarterly, is approximately $75,473.08. To find the accumulated value of an annuity, we can use the formula for the future value of an ordinary annuity:

Accumulated Value = Payment * [(1 + interest rate)^n - 1] / interest rate

Payment (PMT) = $575

Nominal Interest Rate (r) = 13% or 0.13

Number of periods (n) = 17 years * 4 quarters per year = 68 quarters

Substituting the values into the formula, we have:

Accumulated Value = $575 * [(1 + 0.13/4)^68 - 1] / (0.13/4)

Calculating the exponent:

(1 + 0.13/4)^68 ≈ 7.9936

Now we can calculate the accumulated value:

Accumulated Value = $575 * (7.9936 - 1) / (0.13/4) ≈ $75,473.08

Therefore, the accumulated value of the annuity, considering quarterly payments of $575 for 17 years with a nominal interest rate of 13% per year compounded quarterly, is approximately $75,473.08.

The annuity payments are made at the beginning of each quarter, and the interest is compounded quarterly. The formula calculates the accumulated value by summing up the future values of each payment over the specified time period.

The sum of the measures of angle A and angle B is 90 degrees. To determine the value of x, we need to set up an equation based on the given information.

Angle A is given as (5x + 10) degrees, and angle B is given as 3x degrees.

According to the problem, the sum of angle A and angle B is 90 degrees. We can write this as an equation:

(5x + 10) + 3x = 90

Combining like terms, we have:

8x + 10 = 90

Subtracting 10 from both sides:

8x = 80

Dividing both sides by 8:

x = 10

Therefore, the value of x is 10.

Observational study

Step-by-step explanation:

A type of study which does not involve giving the participants or subjects any sort of treatment or undergoing any test. The participants are simply observed or studied over a cwetina period of time on the basis of what the researcher intends to measure before coming up with a conclusion. In the scenario above, employees eating habits is studied without having to undergo any sort of treatment or test, they are only studied in terms of what they eat and other measures of interest.

The distance travelled by the car during this time  by using single  appropriate trapezium is  26.25 and the answer provided is an underestimate

A) Using a single appropriate trapezium, the estimated distance travelled by the car during the 30 seconds is approximately 55 metres.

This is calculated by taking the area of the trapezium formed by the two points of the speed graph: 8m/s and 6m/s.

The area is calculated by taking the average of the two points, multiplied by the time duration:

Area = (8+6/2) * 30

Area = 7*30

Area = 210

The area of the trapezium is then divided by the speed of the car at the start of the journey (8m/s) to get the estimated distance travelled:

Distance = 210/8

Distance = 26.25

This is rounded up to give an estimated distance travelled of 55 metres.

B) The answer of 55 metres is an underestimate of the actual distance travelled by the car. This is because the trapezium method only takes into account the start and end points of the graph, and not any of the other points in between. The actual distance travelled by the car is likely to be higher as the speed of the car is likely to have been greater at points in between the start and end points.

The unknown angle measure based on the information is 35⁰.

An angle is a geometric figure formed by two rays (or lines) that share a common endpoint called the vertex. The rays are typically represented as line segments with the vertex at their endpoint, and the angle is measured in degrees or radians based on the amount of rotation between the two rays.

Angles are commonly denoted using the vertex as the center point and a letter at each end of the rays, for example, angle ABC, where B is the vertex and A and C are the endpoints of the two rays forming the angle.

A. Because he doesn’t like to eat Chinese food too much in a short period of time, p is not really the same for each trial and so we cannot use the binomial distribution to calculate the desired probability.

Step-by-step explanation:

As it is mentioned in the question that he doesn't like the Chinese too much in a very short interval so he prefers various other foods for dinner

So now we have to determine the probability for the next 7 days

So based on the options mentioned, we prefer option A as we do not use the binomial distribution here as it shows only success results that are not confirmed in the given case

Therefore, the correct option is A.

With 60 random samples, the auditor should communicate the finding of the material misstatement to the appropriate level of management.

What is random sampling?

In statistics, sampling is a way of picking a subset of the population from which to draw statistical conclusions. The characteristics of the entire population may be approximated from the sample. Market research sampling may be divided into two types: probability sampling and non-probability sampling.

Now,

Based on the information provided, the auditor should evaluate whether the overstatement of $4,000 in the sample is indicative of a material misstatement in the population of purchase orders.

To do this, the auditor can calculate the projected misstatement and compare it to the tolerable misstatement for purchases.

The projected misstatement can be calculated as follows:

Projected misstatement = (Total population / Sample size) x Sample misstatement

Projected misstatement = (1,200 / 60) x $4,000

Projected misstatement = $80,000

Since the projected misstatement of $80,000 exceeds the tolerable misstatement of $50,000, the auditor should conclude that there is a material misstatement in the population of purchase orders.

As the materiality threshold of the company is $65,000, the auditor should communicate the finding of the material misstatement to the appropriate level of management and consider adjusting the financial statements accordingly. The auditor may also need to perform additional audit procedures to further evaluate the extent of the misstatement and identify the cause of the overstatements.

After the 6-for-1 stock split, the stock price will be $16.41 per share, assuming no market imperfections or tax effects.

A stock split is a process in which a company increases the number of shares outstanding while proportionally reducing the price per share. In this case, the company plans a 6-for-1 stock split, which means that for every existing share, shareholders will receive six new shares.

To determine the post-split stock price, we divide the original stock price by the split ratio. The original stock price is $98.48, and the split ratio is 6-for-1. Therefore, we calculate:

$98.48 / 6 = $16.41

Hence, after the 6-for-1 stock split, the stock price will be $16.41 per share. This means that each shareholder will now hold six times more shares, but the value of their investment remains the same.

It is important to note that in practice, market imperfections, investor sentiment, and other factors can influence the stock price after a split. However, assuming no market imperfections or tax effects, the calculated value of $16.41 represents the theoretical post-split stock price.
