The answer for the given two figure is mBEC is 32° and mPR is 120°

A line that touches a circle only once is said to be tangent to it. A point to circle can only have one tangent. The intersection of the tangent and the circle is known as the point of tangency. Let's now demonstrate that the circle's tangent and radius are perpendicular to one another at their point of contact.

The line segment connecting any two locations on a circle's circumference is referred to as the chord of the circle. It should be remembered that the diameter is the circle's longest chord that runs through its centre.

according to question,

In fig1 mBEC = mAEB - mDEC/2

        mBEC = 94° - 30°/2

        mBEC = 32°

In fig2 mPR = 180° - mPQR

                 = 180° - 60°

                 = 120°

The term that is not affected the standard error of an estimator is population size, from the provide data in options. So, option (c) is right one.

The standard error is a statistical term that used to measured the accuracy that a sample distribution represents a population by using standard deviation. The standard error(SE) is very similar to standard deviation of a distribution. Both are used to measure the spread of distribution. Higher the value SE, the more spread out your data is. In statistical way, standard error is also called standard error of mean, SEM, it represents the deviation of sample mean deviates from the actual mean of a population.

It is calculated simply by dividing the standard deviation by the square root of the sample size. That is [tex]SE = \frac{σ }{\sqrt{n}}[/tex]

where , n --> sample size

σ --> population standard deviations

Now, from the above formula it is clearly seen that standard error term or an estimator affected by sample size (n) and population standard deviations ( σ). So, right choice for answer is population size.

The expression for the number of slices Harris ate is [tex](n/44) - 11.[/tex]

Let s be the number of slices each friend received.

Then the total number of slices on the pizza is n and we have: 44s = n because pizza was evenly divided among the 44 friends). Harris ate 11 fewer slices than he received, so he ate s - 11 slices.

The no of slices he  received is s and we have:

s = (s - 11) + Harris's slices eaten

Substituting 44s = n, we will solve for s:

44s = n

s = n/44

Sorry I forgot how to calculate triangles.

Answer:A. E6

Step-by-step explanation: Just did it :)

The average rate of change of each function on the interval 2 ≤ x ≤ 6 is given as follows:

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.

For the function f(x), we have that:

Hence the rate is given as follows:

r = (2 - 7)/(6 - 2)

r = -5/4

r = -1.25.

For the function g(x), we have that:

Hence the rate is given as follows:

r = (-10.29 - (-7.43))/(6 - 2)

r = -0.715

A circle with center Q and equilateral triangle NOP, where points N and O lie on the circle

What is a circle?

A circle is a two-dimensional shape with a perfectly round boundary that has no corners or edges. It is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the boundary of the circle is called the radius.

The circumference of a circle is the distance around the boundary of the circle, and it is calculated as 2π times the radius. Circles are found in many natural and man-made objects, such as wheels, planets, and coins, and they have a wide range of applications in mathematics, science, and engineering.

To construct a circle with center Q and equilateral triangle NOP where points N and O lie on the circle, follow these steps:

Draw line segment PQ as the base of the equilateral triangle NOP.

Draw a perpendicular bisector of PQ, which intersects PQ at its midpoint, say M. This bisector will be the axis of symmetry of the equilateral triangle NOP.

With M as the center and MP (or MQ) as the radius, draw a circle that intersects PQ at two points, say X and Y.

Using Q as the center and QX (or QY) as the radius, draw two arcs that intersect the circle drawn in step 3 at two points, say N and O.

Draw the lines NQ and OQ to complete the equilateral triangle NOP.

Now, you have a circle with center Q and equilateral triangle NOP, where points N and O lie on the circle.

Answer:

To determine which points lie in the solution set of the system of inequalities x-y>-4, 2x-y<5, and 2y + x>1, we can graph the inequalities on a coordinate plane and look for the region that satisfies all three inequalities.

To graph the inequality x-y>-4, we can first graph the line x-y=-4 by plotting the points on the line:

x y

0 -4

-4 0

Then, we can shade the region above the line, since all points above the line will satisfy the inequality x-y>-4:

 |

-4 |    x

  |   /

  |  /  

  | /  

  |/    

-8 +------

   -4   0

To graph the inequality 2x-y<5, we can first graph the line 2x-y=5 by plotting the points on the line:

x y

0 5

2.5 0

Then, we can shade the region below the line, since all points below the line will satisfy the inequality 2x-y<5:

 |

5 |     x

  |   / |

  |  /  |

  | /   |

  |/    |

 0 +----|--

   0  2.5

To graph the inequality 2y + x>1, we can first graph the line 2y + x = 1 by plotting the points on the line:

x y

0 0.5

1 0

Then, we can shade the region above the line, since all points above the line will satisfy the inequality 2y + x>1:

 |

2 |     x

  |     |

 1|-----

  |   /  

  |  /

  | /  

  |/    

 0 +------

   0   1

The solution set of the system of inequalities is the region that satisfies all three inequalities, which is the shaded region in the graph below:

The area of the composite figure is 343.62 square inches.

What is a 3D composite shape's area?

Composite things that are three dimensional (3D) are created by joining two or more objects. Finding each object's outside surface area and adding the surface areas together will yield the surface area of a 3D composite object.

Area of rectangle = length x width = 12 x 18 = 216 sq in

As a result, the radius is equal to 9 inches, or half the diameter.

[tex]Area \ of\ semicircle = (1/2) * \pi * r^{2} \\\\Area \ of \ semicircle = (1/2) * 3.14 * 9^{2} \\\\Area \ of \ semicircle = 127.62\ sq\ in[/tex]

The combined area of the rectangle and the semicircle is therefore equal to the area of the composite figure as a whole:

Total area = 216 sq in + 127.62 sq in = 343.62 sq in

Answer:

  (a)  $1350.46

  (b)  $50.46

Step-by-step explanation:

You want to know the future value of a $1300 CD earning 1.27% compounded monthly for 3 years, along with the amount of interest earned.

The compound interest formula tells you the future value is ...

  FV = P(1 +r/12)^(12·t)

where r is the annual interest rate and t is the number of years.

Using the given values, we have ...

  FV = $1300(1 +0.0127/12)^(12·3) ≈ $1350.46

(a) The value after 3 years is $1350.46.

The interest earned is the difference between the final value and the amount of the original investment:

  Interest = $1350.46 - 1300.00 = $50.46

(b) The interest earned by the CD is $50.46.

The probability that the secretary will receive 6 calls next hour is approximately 0.090 or 9.0%.

The Poisson distribution is a probability distribution that describes the number of events occurring in a fixed time interval, given the average rate at which events occur and the independence of events. In this case, the average rate of calls is 3 calls per hour.

The probability of receiving exactly 6 calls next hour can be calculated using the Poisson probability formula:

[tex]P(X = 6) = (e^(-λ) * λ^6) / 6![/tex]

where λ is the average rate of calls, e is the base of the natural logarithm, and 6! is the factorial of 6.

Substituting the values, we get:

[tex]P(X = 6) = (e^(-3) * 3^6) / 6! ≈ 0.090[/tex]

If owner asks you to change the method of estimating bad debts to a flat 3% of receivables, then you should carefully "evaluate request to change method of estimating bad-debts", "use prudent and analytical approach" and to communicate effectively with stake-holders.

As a "financial-advisor" for company, it is important to consider request of owner to change method of estimating "bad-debts" to a flat 3% of receivables, given the circumstances described.

(i) It is crucial to understand the reasons behind change in method of estimating bad debts.

In this case, the company is facing a "cash-crunch" and needs to borrow money from the bank, using accounts receivable as collateral.

The owner is aware that many of "accounts-receivable" are more than 90 days past-due, which results in net receivables equal to only 80% of total receivables,

It indicates that company is experiencing a higher level of delinquency in its accounts receivable, and the owner may be seeking a more conservative estimate of bad debts to reflect this situation.

(ii) A more prudent approach would be to conduct a thorough analysis of the company's accounts receivable, considering factors such as the aging of accounts, historical collection patterns, industry norms, economic conditions, and creditworthiness of customers.

This help in developing a more accurate and reliable estimate of bad debts that aligns with the company's specific circumstances.

(iii) it is important to communicate-effectively with owner and other relevant stakeholders, explaining reasons behind recommended method of estimating bad debts and the potential implications of using a flat percentage.

This can help in building transparency, trust, and confidence in the financial reporting process and decision-making of the company.

Answer:

The probability of taking either one job or the other job can be calculated by adding the probabilities of taking the first job and taking the second job, and then subtracting the probability of taking both jobs (since we cannot take both).

Let A be the event of taking the first job, and B be the event of taking the second job. Then, the probability of taking the first job is P(A) = 0.5, and the probability of taking the second job is P(B) = 0.4. The probability of taking both jobs is zero, since we cannot take both.

Therefore, the probability of taking either one job or the other job is:

P(A or B) = P(A) + P(B) - P(A and B)

= 0.5 + 0.4 - 0

= 0.9

So the probability of taking either one job or the other job is 0.9 or 90%
