Answer:

5x-15=x+13

Step-by-step explanation:

I don't know which equation you want me to simplify, so I assume it is, 5(x – 3) = x + 13?

We need at least 10 super taxis to transport 45 people without any mini taxis.

A taxi company has two types of taxis: "super" taxis and "mini" taxis. They have a group of 45 people who need transportation. Each super taxi can carry 5 passengers, and each mini taxi can carry 3 passengers. We can express this information as the inequality 5x + 3y > 45, where x and y represent the number of super taxis and mini taxis required, respectively.

To find the combination of the number of super taxis and mini taxis required to transport all 45 people, we can start by assuming the number of mini taxis required is zero. In this case, the inequality becomes 5x > 45 or x > 9. Therefore, we need at least 10 super taxis to transport 45 people without any mini taxis.

Next, we can check if we need any mini taxis. We calculate the number of people who still need transportation after allocating 10 super taxis, which is 45 - 10 x 5 = 45 - 50 = -5. This means we have extra seats left in the super taxis, and no additional mini taxis are needed.

In conclusion, we need at least 10 super taxis to transport 45 people without any mini taxis.

Answer:

∠F = 32°

Step-by-step explanation:

ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent

∠D = ∠A = 108

∠B = ∠E = 40

∠C = ∠F

In ΔDEF,

∠D +∠E + ∠F = 180        {Angle sum property of triangle}

108 + 40 + ∠F = 180

        148 +∠F = 180

                ∠F = 180 - 148

               ∠F = 32°

Answer:

153* for both

Step-by-step explanation:

This makes a circle, which is 360*. One angle is given, and it is 27*. If the angle on the opposite side is the same, the total degrees so far would be 54.

Say b and c were equal. Then, the remaining 306* would be split even among them. 306/2 is 153.

Therefore, 153* is the correct answer.

The correct value of p(x<8) is 1.875.

To determine how probable something is gonna occur, use probability. It is a number between 0 and 1, where 0 denotes the absence of a possibility and 1 denotes the existence of one. By dividing the number of favorable outcomes by the entire number of potential possibilities, the probability of an occurrence is determined.

To find the probability that is greater than 8, we need to integrate this probability density function from 5.5 to 20.5:

P(X < 8) = ∫[5.5,20.5] f(x) dx

= ∫[5.5,20.5] (1/8) dx

= [x/8] from 5.5 to 20.5

= (20.5/8) - (5.5/8)

= 15/8

= 1.875.

Therefore, the correct probability is 1.875.

Answer:

Step-by-step explanation:

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

Slope = (y2 - y1) / (x2 - x1)

Plugging in the given points, we get:

Slope = (9 - (-7)) / (7 - (-3))

= 16 / 10

= 1.6

So the slope of the line passing through (-3, -7) and (7, 9) is 1.6.

Answer:

m = 8/5

Step-by-step explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

(-3,-7) and (7,9)

We see the y increase by 16 and the x increase by 10, so the slope is

m = 16/10 = 8/5

So, the slope is 8/5

The y-coordinate of the image point of (π/6, 1/2) in the transformed function is -6.5.

The transformed function is y = -3.5 sin (2π/12 (x - 2.5)) - 10. To find the y-coordinate of the image point of (π/6, 1/2), we need to substitute π/6 for x in the transformed function.

y = -3.5 sin (2π/12 (π/6 - 2.5)) - 10

y = -3.5 sin (π/6 - 2.5π/6) - 10

y = -3.5 sin (-π/2) - 10

y = -3.5(-1) - 10

y = 3.5 - 10

y = -6.5

Therefore, the y-coordinate of the image point of (π/6, 1/2) in the transformed function is -6.5.

The probability that all of the offices in the environmental club are filled by members of the debate team is approximately 0.021 or 2.1%.

To find the probability that all of the offices in the environmental club are filled by members of the debate team, we need to use the concept of combinations.

First, we need to find the total number of ways to fill all four offices from a pool of 13 candidates. This can be done using the formula for combinations:

\(C(13,4) = \frac{13!}{4!(13-4)!} = \frac{13\times12\times11\times10}{4\times3\times2\times1} = 715\)

So there are 715 different ways to fill the four offices.

Next, we need to find a number of ways to fill all four offices with members of the debate team. There are 6 members of the debate team, so we need to choose all four of them:

\(C(6,4) = \frac{6!}{4!(6-4)!} = \frac{6\times5\times4\times3}{4\times3\times2\times1} = 15\)

So there are 15 different ways to fill all four offices with members of the debate team.

Finally, we can find the probability by dividing the number of ways to fill all four offices with members of the debate team by the total number of ways to fill the four offices:

P(all offices filled by debate team) = 15/715 ≈ 0.021

Step-by-step explanation:

logx - log(x+5) = log2,

logx = log2 + log(x + 5),

Remember that logs of the same base can be added together by multiplying their arguments:

log(x) = log [(x + 5)*2]

We cancel the logarithms by taking the exponents of both sides:

x = (x + 5)*2,

x = - 10

The statement "As the length of a confidence interval increases, the degree of confidence in it actually containing the population parameter being estimated (confidence level) also increases" is false. The confidence level remains the same regardless of the length of the confidence interval.

The confidence level of a confidence interval is determined before any data is collected and is a measure of the long-term success rate of the procedure used to construct the interval. It represents the probability that the interval will capture the true population parameter in repeated sampling.

The length of a confidence interval, on the other hand, depends on factors such as the variability of the data and the desired level of precision. The length of the interval determines the range of plausible values for the population parameter.

While it is true that a longer confidence interval may capture a wider range of potential values, it does not increase the degree of confidence in containing the true population parameter. The confidence level is fixed at the time of construction and does not change based on the length of the interval. The confidence level provides a measure of the reliability of the estimation procedure, while the length of the interval affects the precision and range of plausible values.

The double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

The iterated integral to compute the double integral over the rectangle r = {(x,y) : 0 ≤ x ≤ π, 0 ≤ y ≤ a} of sin(xy) is given by:

∫∫r sin(xy) dA = ∫₀^a ∫₀^π sin(xy) dx dy

Integrating with respect to x first, we have:

∫₀^a ∫₀^π sin(xy) dx dy = ∫₀^a [-cos(πy) + cos(0)] dy

= ∫₀^a (1 - (-1)^n) dy

= a - (a/π)sin(πa)

For what values of a is ∫∫r sin(xy) dA equal to 1?

We need to solve the equation:

a - (a/π)sin(πa) = 1

Multiplying both sides by π, we get:

aπ - a sin(πa) = π

Now, let f(a) = aπ - a sin(πa) - π. We need to find the values of a such that f(a) = 0.

Using numerical methods, we can find that there is only one solution in the interval [0,π], which is approximately a = 0.986.

Therefore, the double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

Two functions are,

⇒ f(x) = 3x and g(x) = x

Now, Let's take f(x) = 3x and g(x) = x as two functions.

1) To determine the domain and range of the composition of functions, f(g(x)), we must first evaluate g(x), after which we must insert the result into f(x).

Consequently, f(g(x)) = f(x) = 3x

and g(x) = x.

The collection of all x values found in the domain of g(x) is the domain of f(g(x)).

The domain of g(x) is all real numbers in this situation.

Hence, As a result, all real numbers are included in f(g(x))'s domain.

The set of all possible values for f(g(x)) is referred to as the function's range. Since the square of any real number is never negative, the range of f(g(x)) is also the range of non-negative real numbers.

2) The domain and range of the sum and difference of functions, f(x) + g(x) and f(x) - g(x), may be determined by examining the domain and range of each function independently.

The domains of f(x) and g(x) come together to form the domain of f(x) + g(x) and f(x) - g(x).

Both functions in this situation have as their domain all real numbers. Therefore, all real numbers are included in the domain of both f(x) + g(x) and f(x) - g(x).

f(x) and g(x) values determine the range of f(x) + g(x) and f(x) - g(x). All real numbers fall within f(x)'s range, and all non-negative real numbers fall within g(x)'s range. Consequently, all real numbers fall inside the range of f(x) + g(x).

3) Since division by zero is undefined, we must take into account g(x)'s zeros in order to determine the domain and range of the product and quotient of functions, f(x)*g(x) and f(x)/g(x).

The point where the domains of f(x) and g(x) cross is called the domain of f(x) g(x). The domain of f(x) g(x) is therefore limited to real integers alone.

All x values, except the zeros of g(x), are included in the domain of f(x)/g(x). G(x) has zeros when x = 0 since it equals x. All real values, excepting x = 0, are therefore included in the domain of f(x)/g(x).

Based on the values of f(x) and g(x), the range of f(x) g(x) and f(x) / g(x) is determined. F(x) has a real-only domain.

The expression for the height of the box is 3x^(1)y^(-1)z^(1) units.

The volume of a rectangular box is given by the formula V = lwh, where l is the length, w is the width, and h is the height. We are given the volume, width, and length of the box and we are asked to find the expression for its height.

Volume = 60x^(6)y^(6)z^(10)
Width = 2x^(2)y^(3)z^(4)
Length = 10x^(3)y^(4)z^(5)

Substituting the given values into the formula for volume, we get:

\(60x^{(6)}y^{(6)}z^{(10)} = (2x^{(2)}y^{(3)}z^{(4))}(10x^{(3)}y^{(4)}z^{(5))(h)\)

Simplifying the right side of the equation, we get:

60x^(6)y^(6)z^(10) = 20x^(5)y^(7)z^(9)(h)

Dividing both sides of the equation by 20x^(5)y^(7)z^(9), we get:

h = (60x^(6)y^(6)z^(10))/(20x^(5)y^(7)z^(9))

Simplifying the fraction, we get:

h = 3x^(1)y^(-1)z^(1)

Therefore, the expression for the height of the box is 3x^(1)y^(-1)z^(1) units.
