Similar triangles

In the triangles, we have the following possible equations

15/18 = 10/(10 + x)

10/18 = 15/(10 + x)

Solving the equations, we have

150 + 15x = 180

15x = 30

x = 2

10/18 = 15/(10 + x)

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

x = 4.5

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.

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).

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

As per the given data:

maximum average slope = 30°

height of the slide = 6 ft

length of the slide = 11.7 ft

For calculating slope (θ):

sinθ = (P/H) {P is perpendicular and H is hypotunese}

sinθ = (height/length)

sinθ = (6/11.7)

sinθ = 0.512

Using sin inverse:

The probability that the first two bulbs are of the same colour and the last two are of different colours is 25/48.

The probability that the first two bulbs are of the same colour and the last two are of different colours is calculated as follows:

Given:

n(B) = 3 (Number of blue bulbs)

n(G) = 4 (Number of green bulbs)

n(R) = 5 (Number of red bulbs)

Formula: P(A) = n(A) / n(S)

Where,

P(A) = Probability of event A

n(A) = Number of favorable outcomes

The intersection point on the graph has an approximate x-value of 1a.

Making the curve that represents a function on a coordinate plane is the process of graphing a function. If the curve (or graph) represents the function, then each point on the curve will satisfy the function equation.

The line, also called the "curve," has a point at each point that fulfils the function.

The three lines are contemporaneous if they all cross at the same point.

From the second equation,

x = 8y + 19

Putting value of x,

2(8y + 19) + 3y = 0                              9(8y + 19) + 5y = 17

16y + 38 + 3y = 0                                 72y + 171 + 5y = 17

19y = -38                                                77y = -154

 y = -2                                                      y = -2

You'll see that the y value for the answer is the same for the two equations. Simply evaluate the second equation now to find x. Hence, we are aware that the y-coordinate is negative two at some x number.

x = 8(-2) + 19

x = -16 + 19

x = 3

The single point that these three equations share is (3, -2).

4x - 3y = 13                     eq1

-6x + 2y = -7                   eq2

Use the elimination method. Multiply eq1 by eq2 and multiply eq2 by eq3.

8x - 6y = 26                eq1

-18 + 6y = -21              eq2

Adding the equations to eliminate the y terms.

-10x = 5

 x = -1/2

Substituting this value of x into any of the equations to solve for the value of y.

Substituting the first equation into the second equation. In terms of x, this will translate the second equation. From that freshly created equation, find x. Once you solved for x, substitute that value of x into the first equation to solve for y.

You have a vertical line that passes all points that have the x coordinate 7 and you have a horizontal line that passes all point that have the y coordinate -5.

If you were to graph these two lines, they will be intersecting at (7, -5).

Now, draw the following lines on a coordinate system:

i) A vertical line passing through the points (3, 0).

ii) A horizontal line passing through the point (0, 6).

iii) A line passing through the points (0,0) and (1, -3).

Once you have drawn these lines, look for 3 points of intersection.

Area = (base × height) / 2

Lines that have the same slope never intersect.  Put both equations in y=mx+b  form where the slope is the coefficient of x.

The empirical norm therefore states that 68% of 7-year-old kids are between 47 and 51 inches tall.

A column in a table is a collection of cells which are arranged vertically. A field, like the received field, is a sort of element that contains only one item of data. A column in a table usually contains the values for just a single field.

The empirical rule states that in a normal distribution, 68% of the data fall within one average standard deviation. In this instance, the mean difference is 2 inches, while the average height of 7-year-old kids is 49 inches.

We must identify the range among heights that is within one average standard deviation in order to apply the scientific rule. To accomplish this, we can add and subtract the standard variance from the median as follows:

Step-by-step explanation:

To find the sum of the functions, we add them together:

f(x) + g(x) = (5x + 4) + (3x² - 9)

Simplifying, we get:

f(x) + g(x) = 3x² + 9x - 5

Therefore, the sum of the functions is 3x² + 9x - 5, which is option D.

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
