In this scenario, if a computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is $470, and its value 3 years later would be $1410.

The straight-line method of depreciation is a method of calculating the decline in value of an asset over time. Using this method, an asset's value is spread evenly over its useful life.

In this scenario, if the computer was bought for $2350 and is being depreciated over 5 years, the annual depreciation is ($2350 / 5) = $470.

Three years later, the computer's value would be $2350 - ($470 x 3) = $1410. This is because the value of the computer is decreasing by $470 per year, and after three years, the total amount of depreciation would be $470 x 3 = $1410.

It's important to note that the straight-line method of depreciation is a simple method and it does not reflect the real-world scenario in which assets may have a higher value of depreciation in the initial years and less in the later years. But it's easy to calculate and use.

In conclusion, if an asset is depreciated using the straight-line method, its value decreases evenly over its useful life. It's important for businesses to understand the various methods of depreciation and choose the one that best suits their needs.

In an observational study, lurking variables are present but not explicitly accounted for in the study design. These variables may have an effect on the outcome variable and can lead to confounding.

Lurking variables are variables that are not directly measured or controlled in a study, but can affect the relationship between the variables of interest. They can lead to confounding, which is when the effect of one variable on the outcome cannot be separated from the effect of another variable. In an observational study, it can be more difficult to identify and control for lurking variables, which can weaken the ability to draw causal conclusions.

Blinding is a technique used in some studies to reduce bias by hiding the treatment or condition from either the participants, the researchers, or both. In a single-blind study, either the participants or the researchers are unaware of the treatment or condition, while in a double-blind study, both the participants and the researchers are unaware. Blinding can help reduce bias by preventing expectations from influencing the results.

Confounding occurs when the effect of one variable on the outcome cannot be separated from the effect of another variable. This can lead to incorrect conclusions about the relationship between the variables of interest. For example, in a study looking at the relationship between coffee consumption and heart disease, age could be a lurking variable that affects both coffee consumption and the risk of heart disease. If age is not controlled for, it could lead to a false conclusion about the relationship between coffee consumption and heart disease.

Random assignment is a technique used in experimental studies to assign participants to different treatments or conditions at random, which helps to ensure that the groups are similar in all aspects except for the treatment or condition. This reduces the potential for confounding and helps to establish a causal relationship between the treatment or condition and the outcome.

Step-by-step explanation:

We have a bag of :

9 red marbles

6 blue marbles

7 green marbles

11 yellow marbles

Total number of marbles = 33 marbles.

The possibility that a red or green marble will be selected from a bag

P( Red or Green) = P(Red) + P(Green)

In the question we are not told if it is with replacement or without. We do both

With replacement

P( R or G) = P(Red) + P(Green)

P(Red)= 9/33

P(Green) = 7/33

= 16/33

Therefore, the possibility that a red or green marble will be selected from a bag is 16/33

The quadratic formula, providing the solutions for any quadratic equation is \(x = (-b \pm \sqrt(b^2 - 4ac)) / (2a).\)

To derive the quadratic formula, we start with the quadratic equation in standard form: \(ax^2 + bx + c = 0\), where a, b, and c are constants and a ≠ 0.

Step 1: Divide the equation by 'a' to isolate the quadratic term:

\(x^2 + (b/a)x + c/a = 0.\)

Step 2: Move the constant term (c/a) to the right side:

\(x^2 + (b/a)x = -c/a.\)

Step 3: Add (b/2a)^2 to both sides of the equation to complete the square on the left side:

\(x^2 + (b/a)x + (b/2a)^2 = (b/2a)^2 - c/a.\)

Step 4: Simplify the right side:

\(x^2 + (b/a)x + (b^2/4a^2) = (b^2 - 4ac) / (4a^2).\)

Step 5: Factor the left side of the equation:

\((x + b/2a)^2 = (b^2 - 4ac) / (4a^2).\)

Step 6: Take the square root of both sides:

\(x + b/2a = \pm \sqrt((b^2 - 4ac) / (4a^2)).\)

Step 7: Simplify the right side:

\(x + b/2a = \pm \sqrt(b^2 - 4ac) / (2a).\)

Step 8: Finally, isolate 'x' by subtracting b/2a from both sides:

\(x = (-b \pm \sqrt(b^2 - 4ac)) / (2a).\)

Step-by-step explanation:

Answer:

1.5

Step-by-step explanation:

In the given series 3 4.5 6 7.5 9 10.5

\(a_{1}=3\)   ,    \(a_{2}=4.5\)   ,   \(a_{3} =6\)

As the series is arithmetic and in arithmetic series common difference is,

\(d=a_{2}-a_{1}\)

\(d_{1} =4.5-3=1.5\\\)

\(d_{2} =6-4.5=1.5\)

So, common difference is 1.5

Answer:

1. a. 1,000 = 10³ = 10 × 10 × 10

b. 100 × 100 = 10² × 10² = 10 × 10 × 10 × 10

2. a. 3 × 10² = 300

b. 2.16 × 10⁴ = 21,600

c. 800 ÷ 10³ = 0.8

d. 754.2 ÷ 10² = 7.542

Step-by-step explanation:

3. a. 1,000

There are 3 zeros in 1000. This is equivalent to 10 raised to the power of 3. Writing this in multiplication sentence using 19 as the only factor, we would have:

1,000 = 10³ = 10 × 10 × 10

b. 100 × 100

Using the same logic as explained in (a) above, we would have:

100 × 100 = 10² × 10² = 10 × 10 × 10 × 10

2. a. 3 × 10²

Convert 10² to 100 and multiply both numbers

3 × 10² = 3 × 10 × 10 = 3 × 100 = 300

b. 2.16 × 10⁴

2.16 × 10 × 10 × 10 × 10 = 2.16 × 10,000

Multiplying both numbers, since we have 4 zeros, move the decimal point 4 places to the right.

2.16 × 10,000 = 21,600

c. 800 ÷ 10³ = 800 ÷ 10 × 10 × 10

800 ÷ 1,000

There are 3 zeros in 1000, since we are dividing, move the decimal point 3 places to the left.

800 ÷ 1,000 = 0.8

d. 754.2 ÷ 10² = 754.2 ÷ 10 × 10

754.2 ÷ 100

Move the decimal point 2 places to the left.

754.2 ÷ 100 = 7.542

Answer:

Step-by-step explanation:

You want the measures of the angles marked x° and y° in the given diagram.

The measure of an inscribed angle is half the measure of the arc it intercepts. This means any inscribed angles that intercept the same arc will have the same measure.

The inscribed angles with vertices J and K both intercept arc FH, so both have the marked measure of 56°.

  x = 56

The angle where the chords cross (y°) will be half the sum of the arcs those chords intercept. Here, those are arcs FH and JK.

Given that half the arc measure is the measure of the intercepting inscribed angle, we can simply sum the inscribed angles to get y°:

  y° = 56° +19° = 75°

  y = 75

Step-by-step explanation:

i think zero lol i dont know this is wrong or correct lol

It looks like the differential equation is

\(\dfrac{dy}{dx} = 4 (2x+2) \sin\left(x^2 + 2x + \dfrac\pi2\right)\)

A. \(\frac{dy}{dx}\) gives the slope of the line tangent to the curve \(y=y(x)\) at the point \((x,y)\). At the point (0, 4), the tangent line has slope

\(\dfrac{dy}{dx}\bigg|_{x=0,y=4} = 4\sin\left(\dfrac\pi2\right) = 4\)

Then using the point-slope formula, the equation of the line is

\(y - 4 = 4 (x-0) \implies \boxed{y=4x+4}\)

B. Differentiate both sides of the ODE with respect to \(x\). Using the product, chain, and power rules,

\(\dfrac{d^2y}{dx^2} = 8 \sin\left(x^2+2x+\dfrac\pi2\right) + 4(2x+2)^2 \cos\left(x^2+2x+\dfrac\pi2\right)\)

You're probably supposed to evaluate the second derivative at (0, 4), not (0, 3), since we don't know whether (0, 3) is on the solution curve (yet). At this point,

\(\dfrac{d^2y}{dx^2} \bigg|_{x=0,y=4} = 8 \sin\left(\dfrac\pi2\right) + 16 \cos\left(\dfrac\pi2\right) = 8\)

Since 8 > 0, the solution curve is concave upward at (0, 4).

C. Using the point (0, 4) as an initial value, integrating both sides of the ODE with the fundamental theorem of calculus gives

\(\displaystyle y(x) = y(0) + \int_0^x 4 (2u + 2) \sin\left(u^2 + 2u + \frac\pi2\right) \, du\)

In the integral, substitute \(v=u^2+2u+\frac\pi2\) and \(dv=(2u+2)\,du\).

\(\displaystyle y(x) = 4 + \int_{\pi/2}^{x^2+2x+\pi/2} 4 \sin(v) \, dv\)

\(\displaystyle y(x) = 4 - 4 \cos(v) \bigg|_{v=\pi/2}^{v=x^2+2x+\pi/2}\)

\(\displaystyle y(x) = 4 - 4 \left(\cos\left(x^2 + 2x + \frac\pi2\right) - \cos\left(\frac\pi2\right)\right)\)

\(\displaystyle y(x) = 4 - 4 \cos\left(x^2 + 2x + \frac\pi2\right)\)

which we can expand as

\(\cos\left(x^2+2x+\dfrac\pi2\right) = \cos(x^2+2x)\cos\left(\dfrac\pi2\right) - \sin(x^2+2x)\sin\left(\dfrac\pi2\right) \\\\ ~~~~= -\sin(x^2+2x)\)

Then the particular solution to the ODE is

\(\boxed{y(x) = 4 - 4\sin(x^2+2x)}\)

(and we see that \(x=0\) only yields one value \(y=4\), so (0, 3) is indeed not on the curve)

The earnings on an $18,500 savings account vary based on the compounding frequency. Annual compounding yields the highest earnings of $232, followed by quarterly, monthly, and daily compounding with earnings of $17.22, $3.32, and $0.60 respectively.

To compute the earnings for the year on a savings account, we can use the formula for compound interest:

A = \(P(1 + r/n)^{(n\times t)}\)

Where:

A = the total amount (including the principal and earnings)

P = the principal amount (initial savings)

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

t = the number of years

Given:

P = $18,500

r = 1.2% = 0.012

(a) Annually:

n = 1 (compounded once a year)

t = 1 year

A = \(18,500(1 + 0.012/1)^{(1 \times 1)} - 18,500\)

= 18,500(1.012) - 18,500

= 18,732 - 18,500

= $232

The earnings for the year on an annual compounding basis are $232.

(b) Quarterly:

n = 4 (compounded four times a year)

t = 1 year

A = \(18,500(1 + 0.012/4)^{(4 \times 1)} - 18,500\)

= 18,500(1.003)⁽⁴⁾ - 18,500

= 18,517.22 - 18,500

= $17.22

The earnings for the year on a quarterly compounding basis are $17.22.

(c) Monthly:

n = 12 (compounded twelve times a year)

t = 1 year

A = \(18,500(1 + 0.012/12)^{(12 \times 1)} - 18,500\)

= 18,500(1.001)⁽¹²⁾ - 18,500

= 18,503.32 - 18,500

= $3.32

The earnings for the year on a monthly compounding basis are $3.32.

(d) Daily:

n = 365 (compounded daily)

t = 1 year

A = \(18,500(1 + 0.012/365)^{(365 \times 1)} - 18,500\)

= 18,500(1.00003287)⁽³⁶⁵⁾ - 18,500

= 18,500.60 - 18,500

= $0.60

The earnings for the year on a daily compounding basis are $0.60.

In conclusion, The earnings for the year on an $18,500 savings account depend on the compounding frequency. The earnings are highest when compounded annually ($232), followed by quarterly ($17.22), monthly ($3.32), and daily ($0.60).

The compounding frequency affects the frequency at which interest is added to the principal, resulting in different earnings over time. It is important to consider the compounding frequency when assessing the growth of savings and investments, as higher compounding frequencies can lead to greater overall earnings.

The poisson probability distribution is used with a continuous random variab .In a Poisson process, where events occur at a constant rate, the exponential distribution represents the time between them.

In reality, the Poisson likelihood dispersion is regularly utilized with a discrete irregular variable, not a nonstop arbitrary variable. The number of events that take place within a predetermined amount of time or space is modeled by the Poisson distribution. Examples of such events include the number of customers who enter a store, the number of phone calls that are made within an hour, and the number of problems on a production line.

The events are assumed to occur independently and at a constant rate by the Poisson distribution. It is defined by a single parameter, lambda (), which indicates the average number of events that take place over the specified interval. The probability of observing a particular number of events within that interval is determined by the Poisson distribution's probability mass function (PMF).

The Poisson distribution's PMF is defined as

P(X = k) = (e + k) / k!

Where:

The number of events is represented by the random variable X.

The number of events for which we want to determine the probability is called k.

The natural logarithm's base is e (approximately 2.71828).
