The wine quality score for a wine that has an alcohol content of 10% is 73.4. So the option a is correct.

In the given question, this study examined the relationship between wine quality score (winescore) and alcohol content (alcohol) for 160 bottles of red wine.

Wine quality score ranges from 0-100 points, with a higher score indicating a higher quality wine. Alcohol content is measured in percent alcohol content and ranges from 8.4 - 13.6 (e.g. alcohol=9.5 would mean an alcohol content of 9.5%).

The data and question is given below;

We have to predict the wine quality score for a wine that has an alcohol content of 10%.

So, wine quality = 59.3 + 1.41*Alcohol Content

wine quality = 59.3 + 1.41*10

wine quality = 59.3 + 14.1

wine quality = 73.4

Hence, the wine quality score for a wine that has an alcohol content of 10% is 73.4. So the option a is correct.

To solve the quadratic equation by completing the square 11.25 needs to be added to the equation.

The given equation is x²+13x+31 = 0

Let us now solve it by completing the square:

x² + 13x + 31 = 0

or, x² + 2x × 6.5 +6.5² -6.5²+ 31 = 0

or, (x +6.5)² -42.25+31 = 0

or,  (x +6.5)² -11.25 = 0

Therefore we have to add 11.25 to the equation to solve the quadratic equation.

The roots or zeros of the expression on the left side of the equation are the values of x that satisfy the equation. There can only be two possible solutions to a quadratic problem. If there is only one solution, a problem is said to have a twofold root.

The only choices are one real double root, two distinct solutions that are complex conjugates of one another, two real solutions, or two real solutions if all the coefficients have real values.

If complex roots are taken into account, a quadratic equation will always have two roots; a double root counts as two. An equivalent equation can be created by factoring a quadratic equation.

The systematic succession of phases that a product goes through as it develops from start to finish is known as the agile software development life cycle. Concept, conception, iteration, release, maintenance, and retirement are its six phases.

The project management approach a team decides on will have a small impact on the Agile life cycle. For instance, Scrum teams work in sprints, which are brief timeframes akin to iterations. They also have responsibilities that are precisely defined, like Scrum master. Kanban teams, on the other hand, operate more continuously and don't have set roles. Another illustration is Extreme Programming, where teams frequently work in shorter iterations and give engineering practices more attention. Self-organized teams can better adapt to business requirements with a lightweight strategy. All agile frameworks use iterative and incremental development and have a set, defined iteration duration.

James has a total of 62 dimes and 100 quarters in his collection

The given parameters in the question are:

Total count of coins = 162

Worth of coins = $31.20

Represent the dimes with x and the quarters with y

So, we have the following representations

Dimes in dollars = 0.1x

Quarters in dollars = 0.25y

Solving further, we have the following equations

x + y = 162

0.1x + 0.25y = 31.20

Make x the subject in the equation x + y = 162

So, we have the following representation

x = 162 - y

Substitute x = 162 - y in 0.1x + 0.25y = 31.20

0.1(162 - y) + 0.25y = 31.20

Evaluate

16.2 - 0.1y + 0.25y = 31.20

So, we have

0.15y = 15

Divide both sides by 0.15

y = 100

Recall that

x = 162 - y

Depreciation expenses using Straight line is $11,000

Depreciation expenses using Double-declining balance is $18,400

Depreciation expenses using Units of production is $12,500

Straight-line method of depreciation is regarded as the simplest form of depreciation

Given information

Purchase value of equipment = $115,000

Estimated residual value = $5,000

Estimated service life = 10

Deprecation expenses = ($115,000 - $5,000) / 10 years

Deprecation expenses = $110,000 / 10

Deprecation expenses = $11,000

Double-declining balance method is an accelerated depreciation method where asset are depreciated at twice the rate in the straight-line method

Depreciation rate = 1 / Estimated service life

Depreciation rate = 1 / 10

Depreciation rate = 10%

So, the rate is double = 10% * 2 = , 20%

in year 2, Depreciation =  ($115,000 - $23,000) * 20%

Depreciation = $18,400

Formulae for Units-of-production method is (Purchase value of equipment - estimated residual value) / Estimated production units

Units-of-production method = [$115,000 - $5,000] / $220,000 units

Units-of-production method = $110,000 /  220,000 units

Units-of-production method = $0.5 per units

For 2021, Depreciation = Production units in 2021 year * Depreciation per unit

Depreciation = 30,000 units × $0.5

Depreciation = $15,000

For 2022, Depreciation = Production units in 2022 year * Depreciation per unit

Depreciation = 25,000 units * $0.5

Full Question ;

On January 1, 2021, the Allegheny Corporation purchased equipment for $115,000. The estimated service life of the equipment is 10 years and the estimated residual value is $5,000. The equipment is expected to produce 220,000 units during its life. Calculate depreciation for 2021 and 2022 using each of the following methods. Round all computations to the nearest dollar.

1. Straight line

2. Double-declining balance

3. Units of production (units produced in 2021, 30,000; units produced in 2022, 25,000)

Depreciation expense value from different different methods are the following:

a)Using Straight line Method,

depreciation= $13,200

b) Using Double declined balance method,

depreciation=$26,800

c) Using Units of production,

depreciation for 2024 is $ 18,700 and for 2025 is

$ 15,950.

Straight line Method :

A linear basis is a method of calculating depreciation. A process in which an asset is consumed over a period of time longer than it was purchased.

The formula for straight-line depreciation is represented as :

a) Straight line depreciation = (cost of the asset – estimated salvage value) ÷ (estimated useful life of an asset)

We have given that,

Corporation purchased equipment or cost of asset = $134,000

Estimated residual value 0r salvage value

= $2,000

Estimated useful life of the equipment = 10 yr

Expected to produce = 240,000 units

Putting all known values in above formula we get ,

depreciation =( $134,000 - $2,000)/10

= $13,200 per annum

b) Double declined balance method :

It is an accelerated deprecation method where asset are deprecated at twice the rate in straight line Method

depreciated rate =(1 /Estimated useful life) ×100

Rate of deprecated =(2/Estimated useful life) ×100

= 2/10 ×100 = 20%

depreciation= cost of asset × rate of depreciated

= $134,000 × 20% = $26,800

c) Units of production :

Formula of deprecation based on units of production is

depreciation = ( purchased equipment or cost of asset - estimated residual or salvage value ) / ( excepted production units)

so, depreciation = ($134,000 - $2,000)/240,000

= $0.55

For 2024 ,

depreciation= production units in 2024 × depreciation per unit

=$ 34,000× 0.55 = $ 18,700

for 2025 ,

depreciation= production units in 2025 × depreciation per unit

=$ 29,000× 0.55 = $ 15,950

Answer:

  0.253 m/s

Step-by-step explanation:

You want to know the horizontal component of motion of a passenger riding a Ferris wheel when they are 1/27 of the way around the circle and their rate of rise is 0.06 m/s.

The wheel makes one revolution in 27 minutes, so the angular displacement is changing at the rate of (360°)/(27 min) = 13 1/3°/min.

After 1 minute, the passenger is following a path that has an angle of elevation of 13 1/3°.

The ratio of vertical speed to horizontal speed will be the tangent of the angle of elevation:

  Vv/Vh = tan(13 1/3°)

Then the horizontal speed will be ...

  Vh = Vv/tan(13 1/3°) = (0.06 m/s)/0.237004

  Vh ≈ 0.253 m/s

The passenger's horizontal motion is about 0.253 m/s.
