Answer:

Let y(x)="x is valid and x has true premises" and z(x)="x has a true conclusion".

Step-by-step explanation:

The universe U is the collection of all arguments so that x∈U. The statement uses the universal quantifier ∀ represented by the word "Every". The words "valid", "with true premises" and "has a true conclusions" are properties of an argument x.

We can interptet the statement as: "For all x, (x is valid and x has true premises)→(x has a true conclusion)". Symbolically, (∀x)(y(x)→z(x)). The implication → can be read as "if y(x) then z(x)".

-6x=26-20y <br><br><br> -8x=8-20y<br><br><br> solve this system of linear equations
Rashid [163]
Equation 1: -6x = 26 - 20y
Equation 2: -8x = 8-20y

Step 1: Cancel out the Ys

-6x = 26 - 20y --> -6x = 26 - 20y
(-8x = 8-20y) x -1 --> + 8x = -8 + 20y
------------------------
2x = 18
x = 9

Step 2: Plug in X and solve for Y (P.S. you can plus X into either of the equations)

-6(9) = 26 -20y
-54 = 56 - 20y
-80 = -20y
y = 4

Step 3: Check the answer:

-6(9) = 26 - 20(4)
-54 = -54


Therefore:

x = 9 y = 4

7) In 2019, Skylar sold an apartment building for $144,000 cash and a $1,440,000 note due in two years. Skylar's cost of the pro
Ivan

Answer:

(a) he total realized gain is $1,123,200.

(b) § 1250 gain realized in 2019 is, $276,480.

(c) The § 1231 gain realized in 2019 is, $77040.

Step-by-step explanation:

(a)

Compute Skylar's total realized gain under the installment sales method as follows:

Cash Received = $144,000

Note Receivable = $1,440,000

Total Selling Price = Cash Received + Note Receivable

                               = $144,000 + $1,440,000

                               = $1,584,000

Cost of Property = $1,152,000

Deducted Depreciation = $691,200

Adjusted Bias = Cost of Property - Deducted Depreciation

                       = $1,152,000 - $691,200

                       = $460,800

Total Realized Gain = Total Selling Price - Adjusted Bias

                                 = $1,584,000 - $460,800

                                 = $1,123,200

Thus, the total realized gain is $1,123,200.

(b)

§ 1250 gain will be same as the amount of depreciation that was in excess of the straight-line amount.

Thus, § 1250 gain realized in 2019 is, $276,480.

(c)

Total Realized Gain = $1,123,200

§ 1250 gain realized in 2019 = $276,480

§ 1231 gain = Total Realized Gain - § 1250 gain realized in 2019

                  = $1,123,200 - $276,480

                  = $846,720

The total selling price was, $1,584,000.

Compute the percentage of § 1231 gain of the selling price as follows:

§ \text{ 1231 gain}\%=\frac{846,720}{1,584,000}\times 100=53.45455\%\approx 53.5\%

Thus, 53.5% of the cash received will be the § 1231 gain.

§ 1231 gain realized in 2019 = $144,000 × 53.5% = $77,040.

Thus, the § 1231 gain realized in 2019 is, $77040.

What is the measure.. PLS HELP THIS IS URGENT
tangare [24]

The angle of the given ray is of x = 150º.

<h3>What is the angle of the ray?</h3>

The angle of the ray is given by the sum of the angles that compose the ray.

In this problem, the angles are of 65º, 40º and 45º, hence:

x = 65 + 40 + 45 = 150º

You play in a soccer tournament, that consists of 5 games. Each game you win with probability .6, lose with probability .3, and
nasty-shy [4]

Answer:

(a) The joint PMF of W, L and T is:

P(W,\ L,\ T)={5\choose (n_{W}!\times n_{L}!\times n_{T}!)}\times [0.60]^{n_{W}}\times [0.30]^{n_{L}}\times [0.10]^{n_{T}}

(b) The marginal PMF of W is:

P(W=w)={5\choose n_{W}!}\times 0.60^{n_{W}}\times (1-0.60)^{n-n_{W}}

Step-by-step explanation:

Let <em>X</em> = number of soccer games played.

The outcome of the random variable <em>X</em> are:

<em>W</em> = if a game won

<em>L</em> = if a game is lost

<em>T</em> = if there is a tie

The probability of winning a game is, P (<em>W</em>) = 0.60.

The probability of losing a game is, P (<em>L</em>) = 0.30.

The probability of a tie is, P (<em>T</em>) = 0.10.

The sum of the probabilities of the outcomes of <em>X</em> are:

P (W) + P (L) + P (T) = 0.60 + 0.30 + 0.10 = 1.00

Thus, the distribution of W, L and T is a appropriate probability distribution.

(a)

Now, the outcomes W, L and T are one experiment.

The distribution of <em>n</em> independent and repeated trials, each having a discrete number of outcomes, each outcome occurring with a distinct  constant probability is known as a Multinomial distribution.

The outcomes of <em>X</em> follows a Multinomial distribution.

The joint probability mass function of <em>W</em>, <em>L</em> and <em>T</em> is:

P(W,\ L,\ T)={n\choose (n_{W}!\times n_{L}!\times n_{T}!)}\times [P(W)]^{n_{W}}\times [P(L)]^{n_{L}}\times [P(T)]^{n_{T}}

The  soccer tournament consists of <em>n</em> = 5 games.

Then the joint PMF of W, L and T is:

P(W,\ L,\ T)={5\choose (n_{W}!\times n_{L}!\times n_{T}!)}\times [0.60]^{n_{W}}\times [0.30]^{n_{L}}\times [0.10]^{n_{T}}

(b)

The random variable <em>W</em> is defined as the number games won in the soccer tournament.

The probability of winning a game is, P (W) = <em>p</em> = 0.60.

Total number of games in the tournament is, <em>n</em> = 5.

A game is won independently of the others.

The random variable <em>W</em> follows a Binomial distribution.

The probability mass function of <em>W</em> is:

P(W=w)={5\choose n_{W}!}\times 0.60^{n_{W}}\times (1-0.60)^{n-n_{W}}

Thus, the marginal PMF of W is:

P(W=w)={5\choose n_{W}!}\times 0.60^{n_{W}}\times (1-0.60)^{n-n_{W}}
