Answer:

(23, 4)

Step-by-step explanation:

If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.

Step 1: Rewrite 2nd equation

x = 5y + 3

Step 2: Substitution

2(5y + 3) - 5y = 26

Step 3: Distribute

10y + 6 - 5y = 26

Step 4: Combine like terms

5y + 6 = 26

Step 5: Isolate y

5y = 20

y = 4

Step 6: Find x

x - 5(4) = 3

x - 20 = 3

x = 23

And we have our final answer!

Answer:

(23,4)

Step-by-step explanation:

x-5y=3

 +5y=+5y

    x=3+5y

-- Plug that into X for the other Equation

2(3+5y)-5y=26

Solve for y

2(3+5y)-5y=26

Distribute the 2

6+10y-5y=26

Simplify

6+5y=26

-6     =-6

5y=20

(divide by 5)

y=4

plug 4 in the either equation and solve for x

x-5(4)=3

x-20=3

+20=*20

X=23

To add fractions with unlike denominators, follow these steps: find a common denominator, convert the fractions to have the common denominator, add the numerators, simplify (if necessary), and convert to a mixed number or decimal if desired.

Adding fractions with unlike denominators requires finding a common base for both fractions. This common denominator ensures that the fractions can be added together. Once the fractions have the same denominator, add the numerators together while keeping the denominator unchanged. Simplify the resulting fraction if possible by dividing both the numerator and denominator by their greatest common divisor. Finally, you can choose to express the fraction as a mixed number (whole number and proper fraction) or a decimal, depending on the preferred form of the result.

Answer:

5 triangles to 4 circles.

Answer:

1) \(x=15, y=41\)

2) \(x=6, y=24\)

Step-by-step explanation:

1)

The two triangles are similar by AA similarity.

That means \(5x-5=4x+10\).

We can add \(5\) to both sides to get \(5x=4x+15\).

We can then subtract \(4x\) from both sides to get \(x=15\).

We know that the \((5x-5)+(6y-4)=180\)  because they both lie on a straight line.

We can plug in for \(x\) to get \((5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180\).

We can divide both sides of the equation by \(6\) to get \(y-11=30\).

We then add \(11\) to both sides to get \(y=41\).

So, \(\boxed{x=15, y=41}\) and we're done!

2)

Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to \(180^{\circ}\), we have that \(90+3y+18=180\).

We can subtract a \(90\) and an \(18\) from both sides to get \(3y=72\).

We then divide both sides of the equation by \(3\) to get \(y=24\).

We do the same thing for \(x\). On the other side of the trapezoid, we have that \(15x+30+10x=180\).

We combine like terms on the left side to get \(25x+30=180\).

We subtract a \(30\) from both sides to get \(25x=150\).

We divide both sides of the equation to get \(x=6\).

So, \(\boxed{x=6, y=24}\) and we're done!

Answer:

An equation in the form y = mx + b is in the 'slope y-intercept' form where m is the slope and b is the y-intercept. We can rewrite our equation, y = 4, in slope y-intercept form as follows: y = 0x + 4. Here, it is clear that the slope, or m, is zero. Therefore, the slope of the horizontal line y = 4 is zero

Time taken to inflate the balloon to two-thirds of its maximum volume is 16 minutes.

Given the diameter of the balloon = 55 ft

Let r be the radius of the balloon. Then r = 55/2 = 27.5 ft

Rate of change of radius = 1.5 ft/min.

The maximum volume of the balloon = \(\frac{4}{3}\pi r^3\) = \(\frac{4}{3}\times3.14\times 27.5^3\)

                                                              = 87069.583 \(ft^3\)

Two- thirds of the volume = (2/3) x 87069.583 = 58046.389  \(ft^3\)

Let R be the radius of the balloon with two-thirds of its maximum volume.

Then, \(\frac{4}{3}\pi R^3\) =  58046.389

⇒          \(R^3=\frac{3}{4\times3.14}\times 58046.389\) = 13864.583

⇒            \(R=13864.583^\frac{1}{3}\)

⇒           R = 24.023 ft

Now time taken to inflate balloon to the two-third of the maximum volume = 24.023/1.5 = 16 minutes approximately.

The statement "Bash is inherently incapable of floating-point arithmetic, which is why external utilities are utilized." is true.

Bash, as a shell scripting language, primarily deals with integer arithmetic and string manipulation. It does not have built-in support for floating-point arithmetic, making it difficult to perform calculations with decimal numbers. To overcome this limitation, external utilities like 'bc' (Basic Calculator) or 'awk' are often used.

These utilities provide a more versatile way to perform mathematical operations involving floating-point numbers. By utilizing these external tools, Bash scripts can be enhanced to include more complex calculations and data manipulation, expanding their capabilities beyond simple integer operations.

we have shown mathematically that for any nonnegative values t1 and t2, P(X > t1 + t2 | X > t1) = P(X > t2), which demonstrates the "lack of memory" property of the exponential distribution.

To prove the "lack of memory" property of the exponential distribution, we need to show that for any nonnegative values t1 and t2, the following expression is true:

P(X > t1 + t2 | X > t1) = P(X > t2)

Let's start by using the definition of conditional probability:

P(A | B) = P(A ∩ B) / P(B)

In this case, we have A: X > t1 + t2 and B: X > t1. We want to find P(A | B), which is the probability that X is greater than t1 + t2 given that it is greater than t1.

We can rewrite the conditional probability as:

P(X > t1 + t2 | X > t1) = P(X > t1 + t2 and X > t1) / P(X > t1)

Since X is a continuous random variable, we can express these probabilities using the cumulative distribution function (CDF) of the exponential distribution.

P(X > t1 + t2 | X > t1) = [1 - F(t1 + t2)] / [1 - F(t1)]

where F(t) is the CDF of the exponential distribution with parameter λ.

The CDF of the exponential distribution is given by:

F(t) = 1 - e^(-λt)

Substituting this into the equation, we have:

P(X > t1 + t2 | X > t1) = [1 - (1 - e^(-λ(t1 + t2)))] / [1 - (1 - e^(-λt1))]

Simplifying, we get:

P(X > t1 + t2 | X > t1) = e^(-λ(t1 + t2)) / e^(-λt1)

Using the properties of exponents, we can rewrite this as:

P(X > t1 + t2 | X > t1) = e^(-λt2)

which is equivalent to:

P(X > t2)

Practical interpretation:

The "lack of memory" property of the exponential distribution means that the distribution does not remember its past. In practical terms, it implies that the probability of an event occurring after a certain amount of time does not depend on how much time has already passed. For example, if X represents the time until a light bulb fails, and X follows an exponential distribution, then the probability that the light bulb will fail in the next hour is the same regardless of how long the light bulb has already been in use.

Richard gets an average of 17 calls during his 8 hour work day. in order to find the probability that richard will get at most 5 calls in a 2 hour portion of his work day using the poisson distribution,The probability that Richard will receive at most 5 calls in a 2-hour portion of his work day is approximately 0.092.

In this scenario, the random variable X represents the number of calls that Richard receives during a 2-hour portion of his 8-hour work day.

The Poisson distribution is commonly used to model the probability of a certain number of rare events occurring in a fixed interval of time or space. In this case, we can use the Poisson distribution to model the number of calls that Richard receives in a 2-hour period, given that we know the average number of calls he receives in an 8-hour work day.

The Poisson distribution has a single parameter, λ, which represents the average rate at which the rare events occur. In this case, λ = 17/8 = 2.125, since Richard receives an average of 17 calls in an 8-hour work day.

To find the probability that Richard will receive at most 5 calls in a 2-hour portion of his work day, we can use the Poisson probability mass function (PMF), which gives the probability of observing k events in a given time interval, given the average rate λ. The PMF is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

where k is the number of events, λ is the average rate, and e is the mathematical constant approximately equal to 2.71828.

So in this case, we want to find the probability that X ≤ 5, i.e., the probability that Richard will receive 0, 1, 2, 3, 4, or 5 calls in a 2-hour portion of his work day. We can use the cumulative distribution function (CDF) of the Poisson distribution to find this probability:

P(X ≤ 5) = Σ(k=0 to 5) P(X = k)

where Σ is the summation symbol.

Plugging in the values, we get:

P(X ≤ 5) = Σ(k=0 to 5) (e^(-λ) * λ^k) / k! = (e^(-2.125) * 2.125^0 / 0!) + (e^(-2.125) * 2.125^1 / 1!) + (e^(-2.125) * 2.125^2 / 2!) + (e^(-2.125) * 2.125^3 / 3!) + (e^(-2.125) * 2.125^4 / 4!) + (e^(-2.125) * 2.125^5 / 5!) ≈ 0.092

In the given equation r = 2/5 t "r" is the dependent variable.

In mathematics, a variable is a symbol that represents a quantity that can take on different values. In many cases, variables can be divided into two types: dependent variables and independent variables.

An independent variable is a variable that can be changed freely, and its value is not dependent on any other variable in the equation.

A dependent variable is a variable whose value depends on the value of one or more other variables in the equation

Here we have

Lin notices that the number of cups of red paint is always  2/5 of the total number of cups.

She writes the equation r = 2/5 t to describe the relationship.

In the equation, r = 2/5 t, "t" represents the total number of cups, while "r" represents the number of cups of red paint.

Here "t" is the independent variable because it represents the total number of cups, which can be changed arbitrarily.

The value of "r" depends on the value of "t" because the number of cups of red paint is always 2/5 of the total number of cups.
