Answer:

13.5

Step-by-step explanation:

We can solve for x using the side splitter theorem, assuming that the two triangles' bases are parallel.

[tex]\dfrac{\text{segment of left side}}{\text{left side}} = \dfrac{\text{segment of right side}}{\text{right side}}[/tex]

↓ plugging in the lengths given in the diagram

[tex]\dfrac{4}{4 + 5} = \dfrac{6}{x}[/tex]

     [tex]\dfrac{4}{9} = \dfrac{6}{x}[/tex]

↓ cross-multiplying

[tex]4x = 9(6)[/tex]

[tex]4x = 54[/tex]

↓ dividing both sides by 4

[tex]x = 13.5[/tex]

The graph of the solution set can be seen in the image at the end.

Here we have the inequality:

-(6 + 1/2)y + 9 > -17

First, we need to isolate the variable y, then we will get:

9 + 17 > (6 + 1/2)y

26 > 6.5y

26/6.5 > y

4 > y

The graph of this will be an open circle at y = 4, and an arrow that goes to the left, the graph can be seen in the image at the end.

For a survey to put an estimate the proportion of voters who support gun control, the minimum sample size is 752 that is minimum 752 people need to be included in the sample.

We have a survey which is planned to estimate the proportion of voters who support gun control. Margin of error, MOE = 3% = 0.03

Confidence level = 90% = 0.90

No information about the proportion of the voters that is p,so let's assume, p= 0.5

= 1 - 0.90 = 0.10

We have to determine the sample size of people. Using the following formula for computes minimum sample size required to estimate population proportion within the required margin of error, [tex]n ≥ p( 1-p) (\frac{z_c}{MOE})²[/tex]

where, n --> sample size

The equation in the interval [0, 2π) 3csc^2x=4 are: x = π/3 and x = 2π/3.

We can start solving the equation by isolating the csc^2(x) term, using the fact that csc^2(x) = 1/sin^2(x):

3csc^2(x) = 4

csc^2(x) = 4/3

1/sin^2(x) = 4/3

sin^2(x) = 3/4

Taking the square root of both sides, we get:

sin(x) = ±√(3/4) = ±(√3)/2

Since we are looking for solutions in the interval [0, 2π), we need to determine the angles in this interval whose sine is equal to ±(√3)/2. These angles are π/3 and 2π/3, since sin(π/3) = √3/2 and sin(2π/3) = √3/2.

Answer:

Let's use a system of equations to solve the problem.

Let x be the number of regular admission tickets sold, and y be the number of fast pass tickets sold.

From the problem, we know that:

x + y = 104 (equation 1)

and

8x + 22y = 1280 (equation 2)

We can use equation 1 to solve for x in terms of y:

x = 104 - y

Substituting this expression for x into equation 2, we get:

8(104 - y) + 22y = 1280

Simplifying and solving for y, we get:

832 - 8y + 22y = 1280

14y = 448

y = 32

So the student sold 32 fast pass tickets.

To find the number of regular admission tickets sold, we can substitute y = 32 into equation 1 and solve for x:

x + 32 = 104

x = 72

So the student sold 72 regular admission tickets.

Therefore, the student sold 72 regular admission tickets and 32 fast pass tickets.

the values of k for which the equation 2x² + x + 4k has (a) two real solutions are k < 1/32, (b) one real solution is k = 1/32, and (c) no real solutions are k > 1/32.

How to solve the question?

The given equation is 2x² + x + 4k.

(a) For the equation to have two real solutions, the discriminant b² - 4ac must be positive.

Therefore, for this equation, b² - 4ac > 0

=> 1 - 4(2)(4k) > 0

=> 1 - 32k > 0

=> k < 1/32

Hence, all values of k less than 1/32 will give the equation 2x² + x + 4k two real solutions.

(b) For the equation to have one real solution, the discriminant b² - 4ac must be zero.

Therefore, for this equation, b² - 4ac = 0

=> 1 - 4(2)(4k) = 0

=> 1 - 32k = 0

=> k = 1/32

Hence, only the value of k equal to 1/32 will give the equation 2x² + x + 4k one real solution.

(c) For the equation to have no real solutions, the discriminant b² - 4ac must be negative.

Therefore, for this equation, b² - 4ac < 0

=> 1 - 4(2)(4k) < 0

=> 1 - 32k < 0

=> k > 1/32

Hence, all values of k greater than 1/32 will give the equation 2x² + x + 4k no real solutions.

In conclusion, the values of k for which the equation 2x² + x + 4k has (a) two real solutions are k < 1/32, (b) one real solution is k = 1/32, and (c) no real solutions are k > 1/32.

Rounding to the nearest whole number, we predict that the Star Wars Lego Death Star set has approximately 80 pieces. However, it's important to note that this prediction is based solely on the given model and may not necessarily reflect the actual number of pieces in the set.

Step-by-step explanation:

The given equation for the model is y = 0.16x, where y represents the number of pieces in a Lego set and x represents the cost of the set in dollars.

To use this model to predict the number of pieces in the Star Wars Lego Death Star set that costs $499.99, we substitute x = 499.99 into the equation and solve for y:

y = 0.16x

y = 0.16(499.99)

Approximately 39% of coin tosses resulted in tails

Probability is the likelihood or possibility of an event. For example, the probability of tossing a coin  is ½ because there is 1 way to get heads and the total number of possible outcomes is 2 (heads or tails).

Since the coin landed  heads 31 times in 51 tosses, it must be 51 - 31 = 20 times.

We can use the following formula to figure out the percentage of conversions that result in leads.

percentage of tails = (number of tails / total number of spins) x 100

Let's paste the values ​​we have:

percentage of heads = (20/51) x 100

percentage of heads = 0.39215686274 x 100

Step-by-step explanation:

The median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.

The measure of center that should be used to determine which location typically has the cooler temperature is the Median, because Beach Town is skewed.

The median is a measure of center that represents the middle value of a data set when it is arranged in ascending or descending order. When comparing the two histograms, Sunny Town's data is symmetric, meaning that it has roughly equal frequencies on both sides of the center. In this case, the median could be a good representation of the typical temperature in Sunny Town.

However, Beach Town's data is skewed, meaning that it is not symmetrical and has a longer tail on one side of the center. This indicates that there are more occurrences of higher temperatures in Beach Town compared to Sunny Town. In skewed data, the mean can be affected by extreme values, making it less reliable as a measure of center. The median, on the other hand, is less influenced by extreme values and can give a better indication of the typical temperature in Beach Town.

Therefore, the median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.

The length and width of the square picture frame are both approximately 7.08 inches. The dimensions of the picture that would fit inside the frame are approximately 6.5 inches.

In a square, the diagonal is a line segment that connects opposite corners of the square. Since a square has four congruent sides, we can use the Pythagorean theorem to find the length of the diagonal "d" in terms of the length "s" of the sides. The formula used is given by

=> d² = s² + s²

Here we have

The diagonal of the frame is 10 inches

Let's assume that the length and width of the square picture frame are both "x" inches.

Then, using the Pythagorean theorem, we can express the length of the diagonal (d) of the square picture frame in terms of "x":

=> d² = x² + x²  

Simplifying this equation, we get:

=> d² = 2x²

We know that the length of the diagonal is 10 inches, so we can write:

=> 100 = 2x²

Solving for "x", we get:

=> x² = 50

=> x = 5√2

=> x = 7.071 inches

Therefore,

The length and width of the square picture frame are both approximately 7.08 inches.

To find the dimensions of the picture that would fit inside the frame, we can simply subtract a margin of, say, 0.5 inches from each dimension to allow for the picture to fit comfortably within the frame.

So, the dimensions of the picture that would fit inside the frame are approximately 6.5 inches by 6.5 inches.

The function has a minimum value of -2 that occurrs at x = -1

Given that

g(x) = 2x^2 + 4x

This is a quadratic function with a positive leading coefficient (2), which means that it opens upward and so it has a minimum value.

We can find the vertex of the parabola (the point where it changes direction) by using the formula:

x = -b/2a

where a and b are the coefficients of the quadratic function.

In this case, a = 2 and b = 4, so:

x = -4/(2*2) = -1

To find the corresponding y-value (the minimum value of the function), we substitute x = -1 into the function:

g(-1) = 2(-1)^2 + 4(-1) = -2

Therefore, the minimum of the parabola is at the point (-1, -2).
