The correct option is c) Easier interpretation. One of the main advantages of simple models is their ease of interpretation. Simple models tend to have fewer parameters and less complex mathematical equations, making it easier to understand and interpret how the model is making predictions.

This interpretability can be valuable in various domains, such as medicine, finance, or legal systems, where it is important to have transparent and understandable decision-making processes.

Complex models, on the other hand, often involve intricate relationships and numerous parameters, which can make it challenging to comprehend the underlying reasoning behind their predictions. While complex models can sometimes offer higher accuracy or make more detailed predictions, they often sacrifice interpretability in the process.

Answer:

x = 82

Step-by-step explanation:

The bottom angle is the same as the angle next to x + 6

A straight angle is 180 degrees.

You add the given angles: (x + 6) + (x + 10) = 2x + 16

180 = 2x + 16

- 16           -16

164 = 2x

x = 82

C: True. The accounting equation, which is the foundation of all accounting principles, is based on the concept that for every debit entry, there must be an equal credit entry. This principle is reflected in T-accounts, which are used to track the financial transactions of a business.

T-accounts are a visual representation of the accounting equation, where debits are recorded on the left side of the T-account and credits are recorded on the right side. The sum of the debits and credits for each account is calculated and displayed at the bottom of the T-account.

If the sum of debits is not equal to the sum of credits, it indicates that an error has occurred in the recording of financial transactions. This is known as an unbalanced entry, and it must be corrected before the financial statements can be prepared accurately.

Therefore, it is always true that across all T-accounts, the sum of debits must equal the sum of credits. This principle ensures that the accounting records are accurate and reliable, providing stakeholders with a clear and complete picture of a company's financial position.

The radius of the circle inscribed in a 9-12-15 triangle is 3 units

The radius of a circle inscribed in a 9-12-15 triangle can be found using the formula for the inradius (r) of a triangle:

r = A/s

where A is the area of the triangle, and s is the semi-perimeter of the triangle.

Step 1: Find the semi-perimeter (s)
s = (a + b + c) / 2
s = (9 + 12 + 15) / 2
s = 36 / 2
s = 18

Step 2: Find the area (A) of the triangle using Heron's formula:
A = √(s(s-a)(s-b)(s-c))
A = √(18(18-9)(18-12)(18-15))
A = √(18(9)(6)(3))
A = √(2916)
A = 54

Step 3: Find the inradius (r) using the formula r = A/s:
r = 54 / 18
r = 3

Therefore, the radius of the circle inscribed in a 9-12-15 triangle is 3.

TIP:  A circle inscribed in a triangle is a circle that touches all three sides of the triangle exactly once, and it is positioned entirely within the triangle.

GL is equal to √25 + L2, or √5 in its simplest radical form. The Pythagorean Theorem states that the sum of the squares of the two adjacent sides of a right triangle is equal to the square of the hypotenuse.

Given:

GL = ?

m∠KLH = 90°

KH = 5

We can use the Pythagorean Theorem to solve for GL.

GL2 = K2 + L2

GL2 = 52 + L2

GL2 = 25 + L2

Therefore, GL = √25 + L2 = √5.

Given GL, m∠KLH, and KH, we can use the Pythagorean Theorem to solve for GL. The Pythagorean Theorem states that the sum of the squares of the two adjacent sides of a right triangle is equal to the square of the hypotenuse. Therefore, we can calculate the square of GL by taking the square of KH and adding it to the square of L, which is unknown. We square 5 and get 25, then we add L2 to get 25 + L2. We can then take the square root of this to get GL. Therefore, GL is equal to √25 + L2, or √5 in its simplest radical form.

The number of more payments which Mr. Kirov will have to make before the balance becomes 0 is equal to 5 payments.

To calculate the balance, the use of Present Value of an Ordinary Annuity Formula is used. The formula is given as follows:

Present Value =\(P*(\frac{1- [1/(1+r)^n]}{r})\) …. (1)

In the given formula,

PV = Present value or the first balance = $800

P = Monthly payment = $100

r = Monthly interest rate = 0.012

n = number of months (It is equal to total number of payments made until balance turns zero)

Putting the values of above variables into equation (1) and solving for n, we get:

800 = 100*((1 - (1 / (1 + 0.012))^n) / 0.012)

800/100 = (1 - (1 / 1.012)^n) / 0.012

8*0.012 = 1 - (0.9881)^n

0.096 = 1 - (0.9881)^n

⇒ (0.9881)^n = 1 – 0.096

⇒ (0.9881)^n = 0.904

Taking the log of both sides, we have:

n*log(0.9881) = log0.904

n = log0.904 / log0.9881

n = -0.0438315 / -0.005180

n = 8.4608 ≅ 8

Since three payments were already made by Mr. Kirov as per the data in the question, therefore the number of more payments which he will have to make before the balance becomes 0 is calculated as:

Number of extra payments = n – 3 = 8 – 3 = 5 payments

Mr. Kirov's Payment Plan

Balance 1 = $800.00

Payment 1 = $100

New Balance 1 = $700.00

Rate 1 = 0.012

Interest 1 = $8.40

Balance 2 = $708.40

Payment 2 =$100

New Balance 2 = $608.40

Rate 2 = 0.012

Interest 2 = $7.30

Balance 3 = $615.70

Payment 3 = $100

New Balance 3 = $515.70

Rate 3 = 0.012

Interest 3 = $6.19

If Mr. Kirov continues to make monthly payments of $100 and does not make any new purchases, how many more payments will he need to make before the balance is 0?

For two rectangular prisms, the difference of masses of golden rectangular prism with density 19.3 g/cm³ and lead rectangular prism with density 11.3 g/cm³ is equals to the 1728 grams.

There is jacob made two rectangular prisms one from gold and other lead.

Height of each rectangular prism h = 8 cm

length of each rectangular prism, l = 9 cm

width of each rectangular prism, w = 3 cm

The density of golden rectangular prism = 19.3 g/cm³

The density of lead rectangular prism

= 11.3 g/cm³

We have to determine the difference of masses of the rectangular prisms. Using the formula of volume, volume of golden rectangular prism, \(V = l × w × h \)

= 8 × 9 × 3 cm³ = 216 cm³

Similarly, volume of lead rectangular prism = 216 cm³

From density formula, \(d = \frac{ mass}{ volume }\)

=> Mass = density × volume

So, Mass of golden rectangular prism

= 19.3 g/cm³ × 216 cm³

= 216× 19.3 g = 4,168.8 grams

Similarly, Mass of lead rectangular prism = 11.3 g/cm³ × 216 cm³

= 216× 11.3

= 2,440.8 g

The difference between masses of rectangular prism= 4168.8 - 2440.8 = 1728 grams. Hence, required value is 1728 grams.

Answer:

Step-by-step explanation:

We assume you are using a balance, and that weights can be put in either pan. In that case, weight values can be either added or subtracted, so there are 3 possibilities for the contribution each weight makes. In other words, we need to find how many digits are required to count to 40 in base 3.

The largest 3-digit number in base 3 is ...

  3^2 +3^1 + 3^0 = 13 (base 10)

The largest 4-digit number adds 3^3 = 27 to this: 27 +13 = 40.

Hence, we can weigh values 0 to 40 using 4 weights, of sizes 1, 3, 9, 27.

__

Some example weights are ...

  5 = 9 - 3 - 1

  38 = 27 + 9 + 3 - 1

where the "negative" weights are placed in the same pan as the unknown.

Answer:

The margin of error is (31.15, 32.85).

The margin of Error is a statistical expression that is used to determine the percentage point by which the result arrived will differ from the value of the entire population, and it is calculated by dividing the standard deviation of the population by the sample size and lastly multiplying the resultant with the critical factor. A higher error indicates a high chance that the result of the sample reported may not be the true reflection of the whole population. The formula for the margin of error is calculated by multiplying a critical factor (for a certain confidence level) with the population standard deviation. Then the result is divided by the square root of the number of observations in the sample.

Mathematically, it is represented as,

Margin of Error = Z * ơ / √n

Given:

Number of people = n = 16

Mean = μ = $32

Standard deviation = σ = $7

Confidence level = 95%

Thus, the z value would be 1.96.

The confidence interval can be calculated as follows:

Confidence interval = μ ± z(σ/√n)

= 32 ± 1.96 × (7/16)

= 32 ± 0.85

= (31.15, 32.85)

Thus, the margin of error is (31.15, 32.85).

Answer:

Area of the figure = 171 in²

Step-by-step explanation:

Composite figure given in the picture comprises of three figures, two right triangles and one rectangle.

Area of the composite figure = Area of two right triangles + Area of the rectangle at the center

Area of one right triangle = \(\frac{1}{2}(\text{Base})(\text{Height})\)

                                           = \(\frac{1}{2}(12)(9)\)

                                           = 54 in²

Area of the rectangle = Length × Width

                                    = 7 × 9

                                    = 63 in²

Area of the composite figure = 2(54) + 63

                                                  = 108 + 63

                                                  = 171 in²

Answer:

C choice.

Step-by-step explanation:

Since line a is given a slope as -4.

Another line which is line b is given that it's perpendicular to line a or we can say that line a is perpendicular to line b.

Perpendicular is defined as:

\( \displaystyle \large{m_1m_2 = - 1}\)

Both slopes multiply and yield -1.

We know that m1 is -4; we want to find m2 which is slope of line b.

\( \displaystyle \large{ - 4m_2 = - 1}\)

Divide both sides by -4.

\( \displaystyle \large{ \frac{ - 4m_2}{ - 4} = \frac{ - 1}{ - 4} } \\ \displaystyle \large{ m _2 = \frac{1}{4} }\)

Therefore, the slope for line b is 1/4.

Thus, the C choice is correct.
