What is the law of sines?

According to the law of sine, or sine law, the ratio of a triangle's side length to the sine of the opposing angle remains constant for all three sides. The sine rule is another name for it.

Here,

According to the law of sines

BC/sin A = AC/sin B = AB/sin C

∠A = 43°, ∠B = 31°, ∠C = 180° - ∠A - ∠B = 106°

AB = 21 miles

So, BC = (AB/SinC)×SinA

BC = 14.9 miles

Option B is the correct choice.

Based on the findings, the following list compares the portfolios' overall performances, ranking them from best to worst:

Portfolios 2, 3, and 1, respectively.

The weighted average ROR is calculated by adding the rates of return on the portfolio's assets and the percentage of the portfolio that is invested in each investment.

For Portfolio 1:

Total Investment= $700 + $2575 + $220 + $1000 + $1430 = $5925

Therefore, total investment = $5,925

Weighted Average ROR= (-3.8% * $700) / $5925 + (2.1% * $2575) / $5925 + (11.3% * $220) / $5925 + (5.8% * $1000) / $5925 + (1.6% * $1430) / $5925

WAROR = (-0.0045) + 0.0091 + 0.0042 + 0.0098 + 0.0039 = 0.0225

Therefore, the Weighted Average ROR= 2.25% (third)

For Portfolio 2:

Total Investment = $1250 + $1700 + $1515 + $1345 + $1,675 = $7485

Therefore, Total Investment = $7,485

Weighted Average ROR = (-3.8% * $1250) / $7485 + (2.1% * $1700) / $7485 + (11.3% * $1515) / $7485 + (5.8% * $1345) / $7485 + (1.6% * $1,675) / $7485

= (-0.0063) + 0.0048 + 0.0229 + 0.0104 + 0.0036 = 0.0354

Therefore, the Weighted Average ROR = 3.54% (first)

For Portfolio 3:

Total Investment = $1025 + $500 + $790 + $250 + $2500 = $5065

Therefore, Total Investment = $5,065

Weighted Average ROR = (-3.8% * $1025) / $5065 + (2.1% * $500) / $5065 + (11.3% * $790) / $5065 + (5.8% * $250) / $5065 + (1.6% * $2,500) / $5065

= (-0.0077) + 0.0021 + 0.0176 + 0.0029 + 0.0079 = 0.0228

Therefore, Weighted Average ROR = 2.28% (second)

Therefore, the correct order of portfolios based on the performance from best to worst will be:

Portfolio 2, Portfolio 3, and Portfolio 1. (Option B)

If all other values remain constant, an increase in sample size will result in a broader confidence interval when constructing one.

The definition of the MoE, or margin of error, is

MoE = sigma ÷ sqrt(n)

The population standard deviation is represented by sigma. If you don't know sigma, utilize s to get a rough idea of it. The sample standard deviation is denoted by the variable s.

The MoE increases along with the sigma. The width or narrowness of the confidence interval is directly determined by the MoE. A smaller MoE indicates greater confidence with less error, whereas a larger MoE indicates greater net casting but increased error.

The expression that represents the area of the triangle is given as follows:

A = (c - a)[8 - (c - a)]/4.

The area of a triangle is obtained as half the multiplication between the base b and the height h, that is:

A = 1/2 x b x h.

For the triangle in this problem, the base is composed by these following vertices:

Hence the length of the base is of:

b = c - a.

The height is given by the difference between the y-coordinate of the vertex (b,4) and the midpoint of the base ac, hence:

h = 4 - (c - a)/2 = [8 - (c - a)]/2

Hence the area is given as follows:

A = 1/2 x (c - a) x [8 - (c - a)]/2

A = (c - a)[8 - (c - a)]/4.

The problem asks for which expression gives the area of the triangle with these vertices.

Step-by-step explanation:

0.75 liters is the same as 750 grams.

So, the total mass of the mixture is [tex]300+150+750=1200[/tex] g.

This means the ratio is [tex]\frac{300}{1200}=\frac{1}{4}[/tex].

Answer:

Flour : total mass = 1 : 4

Step-by-step explanation:

Given ingredients for the cake:

First convert the mass of the water to the same SI units as the other ingredients.

1 liter = 1000 g

⇒ Water = 0.75 liters = 750 g

Total mass of the mixture:

= flour + sugar + water

= 300 g + 150 g + 750 g

= 1200 g

Therefore, the flour to total mass ratio is:

⇒ Flour : total mass = 300 : 1200 = 1 : 4

A poker hand is a combination of 5 cards from the pack of 52 cards.

One hand full is said when we have 2 cards of the same rank.

In this question, we have to find the probability of 2 hands full of different ranks.

So,

We use the formula : C(n,k)=\frac{n!}{k!(n-k)!}

From permutations and combinations, since order doesn't exist.

From a suit of 13 cards any two cards are chosen:

C(13,2)=\frac{13!}{2!(13-2)!}

C(13,2)=\frac{13×12×11!}{2!11!}

C(13,2)=\frac{13×12!}{2!}

C(13,2)=156/2

C(13,2)=78

78 ways are there to choose for each of the pairs .

Now,

If one of the ranks is of any particular suit or maybe a face card out of which two of them are chosen.

C(4,2)=\frac{4!}{2!(4-2)!}

C(4,2)=6

And same for the other sets of cards of another pair.

We have 78×6×6= 2808 ways to pick the first 4 cards.

Now,

For the fifth card which can be any card except for the paired suit i.e, 13-2=11

There are 4 suits to pick from, 4×11= 44 cards to pick for the final card.

For the first card = 2080

For the fifth card= 44

Total number of two pair hands possible= 2080×44= 123,552

Out of:

C(52,5)=\frac{53!}{5!(52-5)!}

C(52,5)= 2,598,960

Probability of event= 123,552/2,598,960

= 0.4753901560624

Final answer= 0.4754

The probability of being dealt a two-pair is 0.4754.

Given;

What is the likelihood of receiving a two-pair when dealing a five-card poker hand from a 52-card deck that has been properly shuffled?

We use combinations to solve the given case;

From each suit, any two cards are chosen,

C(13,2) = [tex]\frac{13!}{2!(13-2)!}[/tex]

           = [tex]\frac{13*12*11!}{2!11!}[/tex]

           = 156/2

           = 78

Hence, there are 78 ways to choose for each of the pairs.

Now,

If one of the ranks is a face card, two of them are chosen, or if one of the ranks is a certain suit.

C(4,2) = [tex]\frac{4!}{2!(4-2)!}[/tex]

          =6

Similar to the other sets of cards of another pair.

We have 78×6×6= 2808 ways to pick the first 4 cards.

Now,

The fifth card, which can be any card other than the paired suit, is dealt as follows: 13 - 2 = 11.

There are 44 cards total to choose from among the 4 suits, or 4 x 11.

2080 for the primary card.

44 for the fifth card.

Possible two-pair hands total 2080 x 44 = 123,552.

Then,

C(52,5) = [tex]\frac{53!}{5!(52-5)!}[/tex]

            = 2,598,960

Probability of event = Possible two-pair hands / Total outcome

                                 = 123,552 / 2,598,960

                                 = 0.47539

Hence, the probability of being dealt a two-pair is 0.4754.

Step-by-step explanation:

Given a figure showing two triangles with a common side, and two marked angles not at either end of that side, you want to know the applicable congruence postulate.

The letters S and A in the congruence postulate references refer to "Side" and "Angle". The sequence of the letters corresponds to the sequence of corresponding parts in the triangles.

In the given figure, two angles in each triangle are marked with a single arc and a double arc. The triangles share a side that has the double-arc angle at one end. Hence, the sequence of corresponding parts can be seen to be (common) Side - (double-arc) Angle - (single-arc) Angle. The SAA congruence postulate applies.

The rewritten expression will be 4a³ and the value of this expression is -500.

Given in the question:

(2a⁴)² / a⁰a⁵

We know that

(xy)ⁿ = xⁿ × yⁿ ... (i)

We can use equation (i) for the next step of our given expression.

In the case of the numerator:

(2a⁴)² = 2² × a⁸ = 4a⁸

Now, we know, any number to the power of zero is 1.

So, for the denominator, we get:

a⁰a⁵ = 1 × a⁵ = a⁵

We know,

pˣ / pʸ = y ⁽ˣ⁻ʸ⁾ ... (ii)

Using this equation, we can further simplify the given expression:

⇒ 4a⁸ / a⁵

⇒ 4 a⁽⁸ ⁻ ⁵⁾

⇒ 4 a ³ ... (iii)

Now, in the second part of the question, we need to find the value of the expression.

Given a = -5

Putting this value in equation (iii) we get:

4 a ³

⇒ 4 (-5) ³

⇒ 4 × (-125)

⇒ -500

Hence, the simplified expression is 4 a ³ and the value of the simplified equation is -500.
