In the given triangle of attached figure , the required value of x and y is given by option d. x=24.0,y=46.4 ( nearest tenth ).

Let us consider triangle name of the attached figure be ABC,

From vertex A perpendicular line intersect BC at point D.

From the attached figure,

Measure of ∠B = 45°

Measure of ∠C = 30°

Side length AC = 34 units

Side length AB = x units

Side length BC = y units

In triangle ADC,

sin C = AD / AC

Substitute the value we have,

⇒ sin 30° = AD / 34

⇒ AD = ( 1/2 )× 34

⇒ AD = 17

And cos C = CD / AC

Substitute the value we have,

⇒ cos 30° = CD / 34

⇒CD = 34 × cos 30°

⇒ CD = 34 × (√3 /2 )

⇒ CD = 29.45 units

In triangle ADB,

sin B = AD/ AB

⇒ sin 45° = 17 / x

⇒ x = 17 / sin 45°

⇒ x = 17 / ( 1/√2)

⇒ x = 17√2

⇒ x= 24.038 units

⇒ x= 24.0 units ( nearest tenth )

Now in triangle ABD,

cos B = BD/ AB

⇒ cos 45° = BD / 24.0

⇒ BD = 24 × cos 45°

⇒ BD = 24× (1/√2)

⇒ BD = 16.97units

y = BD + CD

 = 16.97 + 29.45

 = 46.42

  = 46.4 units ( nearest tenth )

Therefore , the value of x and y from the attached figure is equal to option d. x=24.0,y=46.4.

1). 1/4

2). 11/15x

3). 3x/7

1. To add or subtract the rational expressions 5/8 and 3/8x, we need a common denominator. The smallest common denominator is 8x, so we can rewrite each expression with a denominator of 8x:

5/8 = 5x/8x

3/8x = 3/8 * 1/x = 3x/8x

Now we can combine the numerators and simplify:

5x/8x - 3x/8x = (5x - 3x)/8x = 2x/8x = 1/4

Therefore, 5/8 - 3/8x = 1/4.

2. To add or subtract the rational expressions 9/15x and 2/15x, we again need a common denominator. The smallest common denominator is 15x, so we can rewrite each expression with a denominator of 15x:

9/15x = 3/5x

2/15x = 2/15 * 1/x = 2/15x

Now we can combine the numerators and simplify:

3/5x + 2/15x = (9 + 2)/15x = 11/15x

Therefore, 9/15x + 2/15x = 11/15x.

3. To add or subtract the rational expressions 5x/7 and -2x/7, we already have a common denominator of 7. We can simply combine the numerators:

5x/7 - 2x/7 = (5x - 2x)/7 = 3x/7

Therefore, 5x/7 - 2x/7 = 3x/7.

The probability that a person chosen at random from this group will either seek further assistance or merely study at home is 5/6, or roughly 0.833. (rounded to three decimal places).

Typically, the probability is defined as the ratio of favourable events to all other outcomes in the sample space. The formula for probability of an occurrence is P(E) = (Number of favourable outcomes) (Sample space).

The formula is as follows:

P(AorB) = P(A)+P(B)-P(AandB)

where A and B are two events.

Then, we have:

P(A) = 30/60 = 1/2 (since 30 out of 60 students go for extra help)

P(B) = 22/60 (since 22 out of 60 students study at home only)

Using the formula, we can then find:

P(AorB) = P(A)+P(B)-P(AandB)

= 1/2 + 22/60 - 0

= 5/6

Hence, the probability that someone chosen at random from this group will either seek further assistance or merely study at home is 5/6, or roughly 0.833. (rounded to three decimal places).

The solution of linear equations is (x, y) = (-0.8905, 0.708).

To solve this system of linear equations by elimination, first multiply both equations by the same number so that when you add the equations together, one of the variables is eliminated. In this case, we'll multiply the first equation by 3 and the second equation by 8.

8(8x+3y=-5)

3(3y=x+4)

24x + 9y = -15

24y = 8x + 32

Now add the two equations together:

24x + 24y = -15 + 32

24x + 24y = 17

Simplifying this equation, we get:

24y = 17

y = 17/24

y = 0.708

Now, plug in the value of y into one of the original equations to solve for x. We'll use the first equation:

8x + 3(0.708) = -5

8x + 2.124 = -5

8x = -7.124

x = -7.124/8

x = -0.8905

The three equations that have the same value of x as the original equation are:

18x - 15 = 72

3(6x - 3) = 72

x = 4.5

What is an equation?

An equation is a statement that two expressions are equal. It typically contains one or more variables (represented by letters) and mathematical operations such as addition, subtraction, multiplication, and division. Equations can be used to represent relationships between quantities or to solve for unknown values.

The correct options are:

18x - 15 = 72

18x - 9 = 72

x = 4.5

To see why, we can start by simplifying the original equation:

Three-fifths (30x - 15) = 72

(3/5)(30x - 15) = 72

18x - 9 = 72

18x - 15 = 72 + 15

18x = 87

x = 87/18

So we see that x = 87/18 is the solution to the original equation.

Now let's check each of the answer choices:

18x - 15 = 72

Solving for x, we get x = 87/18, which is the same as the solution to the original equation. This equation is equivalent to the original equation.

50x - 25 = 72

Solving for x, we get x = 97/50, which is not the same as the solution to the original equation. This equation is not equivalent to the original equation.

18x - 9 = 72

Solving for x, we get x = 81/18 = 9/2, which is not the same as the solution to the original equation. This equation is not equivalent to the original equation.

3(6x - 3) = 72

Simplifying, we get 18x - 9 = 72, which is equivalent to the second equation listed above. So this equation is also equivalent to the original equation.

x = 4.5

This is the same solution as the original equation, so this equation is also equivalent to the original equation.

Therefore, the three equations that have the same value of x as the original equation are:

18x - 15 = 72

3(6x - 3) = 72

Step 3:

Factorize:

[tex]2x(x + 4) = 0[/tex]

Either [tex]2x = 0[/tex]        
∴ [tex]x = 0[/tex]

Or [tex]x + 4 = 0[/tex]

[tex]32 - 4 + 4y + 8 = 0[/tex]

[tex]32 - 4 + 8 + 4y = 0[/tex]

[tex]36 + 4y = 0[/tex]

To prove that EVPI > 0 for the simple decision sapling, we need to understand what EVPI is. EVPI stands for Expected Value of Perfect Information, and it is the difference between the expected value of the decision with perfect information and the expected value of the decision without perfect information.

For the simple decision sapling, we have two options: a sure thing of value r, and a risky gamble with a random payoff G. The expected value of the decision without perfect information is simply the maximum of the two options:
EV = max(r, EG)
The expected value of the decision with perfect information is the maximum of the two options, knowing the outcome of the gamble:
EVPI = max(r, G) - max(r, EG)
Since we know that G is a random variable, the expected value of G is simply the average of all possible outcomes. Therefore, the expected value of the decision with perfect information is simply the maximum of the two options, knowing the average outcome of the gamble:
EVPI = max(r, EG) - max(r, EG) = 0
Therefore, EVPI > 0 for the simple decision sapling.

To prove that the EVPI will be larger if the random payoff of the gamble is replaced by a noisy version of the original gamble, we need to understand how the expected value of the decision changes with the addition of the noise variable Y. The expected value of the decision without perfect information is now:
EV = max(r, EG + EY) = max(r, EG)
Since EY = 0, the expected value of the decision without perfect information does not change. However, the expected value of the decision with perfect information now becomes:
EVPI = max(r, G + Y) - max(r, EG)
Since Y is a random variable with mean 0, the expected value of Y is 0. However, the variance of Y is not necessarily 0, which means that the addition of Y adds variability to the decision. This means that the expected value of the decision with perfect information is now larger, because we have more information about the possible outcomes of the gamble. Therefore, the EVPI will be larger when the random payoff of the gamble is replaced by a noisy version of the original gamble.
