Answer:

x = 10

Step-by-step explanation:

To find the value of x that will make the area of both figures to be equal, set the expression for the area of one figure equal to the other.

Thus:

(x + 5)×12 = x × 18

Solve for x

12x + 60 = 18x

Subtract 12x from each side

12x + 60 - 12x = 18x - 12x

60 = 6x

Divide both sides by 6

60/6 = 6x/6

10 = x

x = 10

The probability will be b) 4/(52 13)

In a standard deck, there are four suits (hearts, diamonds, clubs, and spades), each containing 13 cards. To find the probability of obtaining a bridge hand with all 13 cards of the same suit, we need to determine the number of favorable outcomes (hands with all 13 cards of the same suit) and divide it by the total number of possible outcomes (all possible bridge hands).

Calculate the number of favorable outcomes

There are four suits, so for each suit, we can choose 13 cards out of 13 in that suit. Therefore, there is only one favorable outcome for each suit.

Calculate the total number of possible outcomes

To determine the total number of possible bridge hands, we need to calculate the number of ways to choose 13 cards out of 52. This can be represented as "52 choose 13" or (52 13) using the combination formula.

Calculate the probability

The probability is given by the ratio of the number of favorable outcomes to the total number of possible outcomes. Since there is one favorable outcome for each suit and a total of 4 suits, the probability is 4 divided by the total number of possible outcomes.

Therefore, the probability that a bridge hand will contain all 13 cards of the same suit is 4/(52 13).

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

first x-2=2, then x-2(+2)=2(+2)  which would give us,

x=4

*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.

Answer is 66.

I hope it will help you:)

Answer:

= 66

Step-by-step explanation:

The two integers are -22 and -24, because they are both even and consecutive, and adding them equals -46.

-24 divided by 4 is -6, and -22 plus 11 is -11

Now all we have to do is find the product (multiply  -11 and -6)

And this gives us the answer: 66

Rounding to the nearest thousandth, the margin of error for this survey, expressed as a proportion, is approximately 0.020.

To calculate the margin of error for a survey, we can use the formula:

Margin of Error = Z × √((p × (1-p)) / n)

Where:

Z represents the z-score corresponding to the desired confidence level,

p represents the proportion of respondents who preferred candidate A,

n represents the sample size.

The sample size (n) is 1900, and the proportion of respondents who preferred candidate A is 1520/1900.

p = 1520/1900

≈ 0.8

We need to find the z-score corresponding to a 95% confidence level. For a 95% confidence level, the z-score is approximately 1.96.

Substituting the values into the formula:

Margin of Error = 1.96 × √((0.8 × (1-0.8)) / 1900)

Calculating the expression inside the square root:

(0.8 × (1-0.8)) ≈ 0.16

Margin of Error = 1.96 × √(0.16 / 1900)

Calculating the square root:

√(0.16 / 1900) ≈ 0.01016

Margin of Error = 1.96 × 0.01016

≈ 0.0199

The parent function of a quadratic equation is f(x) = x². The function that is transformed to the right and down from the parent function with a minimum is given by f(x) = a(x - h)² + k.

The equation has the same shape as the parent quadratic function. However, it is shifted up, down, left, or right, depending on the values of  a, h, and k.

For a parabola to have a minimum value, the value of a must be positive. If a is negative, the parabola will have a maximum value.To find the vertex of the parabola in this form, we use the vertex form of a quadratic equation:f(x) = a(x - h)² + k, where(h, k) is the vertex of the parabola.The vertex is the point where the parabola changes direction. It is the minimum or maximum point of the parabola. In this case, the parabola is transformed to the right and down from the parent function, f(x) = x². Therefore, h > 0 and k < 0.

Complemtary angles

Step-by-step explanation:

they add up to 90* as visible by the right angle symbol

Since the rectangular prism and pyramid have congruent bases and height, they are similar. Therefore, the ratio of their volumes is equal to the cube of the ratio of their corresponding side lengths.

Let's call the side length of the base of the pyramid "x". Then, the volume of the pyramid is:

V(pyramid) = (1/3) x^2 * h

where h is the height of the pyramid. We know that V(pyramid) = 48 in.3, so:

48 = (1/3) x^2 * h

Since the rectangular prism has the same base as the pyramid, its base also has side length "x". The height of the prism is also equal to the height of the pyramid. Therefore, the volume of the rectangular prism is:

V(prism) = x^2 * h

To find V(prism), we need to know the value of h. We can use the equation above to solve for h:

48 = (1/3) x^2 * h
144 = x^2 * h
h = 144/x^2

Now we can substitute this value of h into the equation for V(prism):

V(prism) = x^2 * (144/x^2)
V(prism) = 144 in.3

Therefore, the volume of the rectangular prism is 144 in.3.

Step-by-step explanation:

Break it up into two trapezoids as shown

area = trap1 + trap2

      = 2 *   (7+3) / 2   + 3 *  ( 7 + 3) / 2 = 10 + 15 = 25 units^2

Therefore, the value of x that divides the area bounded by the x-axis and the function 3/(2y^2) = x^3 into two sectors of equal area is [(4/9)ln(2y^2)/a^3]^(-1/3).

To find a value of x that divides the area bounded by the x-axis and the function 3/(2y^2) = x^3 into two sectors of equal area, we need to solve for x.

The area bounded by the x-axis and the function is given by:

A = ∫(3/(2y^2)) dx from x = 0 to x = x

Using u-substitution with u = 2y^2 and du/dx = 6x^2, we can rewrite the integral as:

A = ∫(3/u) du/6x^2 from u = 0 to u = 2y^2

A = (1/2) ln(u) / 6x^2 from u = 0 to u = 2y^2

A = (1/2) ln(2y^2) / 6x^2 - (1/2) ln(0) / 6x^2

Note that the ln(0) term is undefined and can be ignored since we are only interested in finding the value of x that divides the area into two equal parts.

To find the value of x that divides the area into two equal parts, we set the integral expression equal to half of the total area:

(1/2) ln(2y^2) / 6x^2 = 1/2 ∫(3/(2y^2)) dx from x = 0 to x = a

Simplifying and solving for x, we get:

x = [ln(2y^2) / 9 ∫(3/(2y^2)) dx from x = 0 to x = a)]^(-1/3)

Evaluating the integral and simplifying further, we get:

x = [(4/9)ln(2y^2)/a^3]^(-1/3)

By dividing the output power (work completed) by the input power ratio, the motor's efficiency may be determined. In this instance, the input power is 300 W, and the output power is 2400 joules (400 N * 6.0 m). As a result, the motor has an efficiency of 2400 J/300 W, or 8.0.

The input power is 300 W.

Time (t) = 20 s

Height is 6.0 metres.

(F) = 400 N Load

Output power (Pout) is calculated as follows: F x h = 400 N x 6.0 m = 2400 J

Efficiency (e) is calculated as Pout / P = 2400 J / 300 W = 8.0.

A motor's efficiency can be determined by dividing its output power by its input power. Assuming that the input power is 300 W and the output power equals the amount of work completed, the load (F) and height can be multiplied to determine the output power (h). The output power in this example is 2400 joules (400 N * 6.0 m) since the load is 400 N and the height is 6.0 m. The motor's efficiency is 2400 J/300 W, or 8.0, as a result. Knowing the input power, output power, and length of time it took the motor to lift the load will help you determine the efficiency. In this illustration, the time is 20 s, and the input power is 300 W.

There are 3900 ways to elect people to the positions of president, vice-president, and secretary.

In this problem, we can use the multiplication rule of counting which states that "if an operation can be performed in m ways and a second operation can be performed in n ways, then the two operations can be performed in m x n ways." Here, since no person can hold more than one office, we can consider the elections for each position independently.

President: There are 10 people running for this position. Thus, we can choose the president in 10 ways. Vice-President: Since the person who has been chosen as the president cannot hold any other position, we can choose the vice-president in 19 ways. Secretary: Since the two people who have been elected as president and vice-president cannot hold any other position, we can choose the secretary in 18 ways. Therefore, by the multiplication rule of counting, the total number of ways in which these people can be elected to these positions is 10 x 19 x 18 = 3,900 ways.
