Answer: 1/6

Step-by-step explanation:

Out of 30 students, 5 liked country music.

To find the fraction of students who liked country music, we need to divide the number of students who liked country music by the total number of students in the class.

Fraction of students who liked country music = (Number of students who liked country music) / (Total number of students)

Fraction of students who liked country music = 5/30

We can simplify this fraction to lowest terms by dividing both the numerator and denominator by the greatest common factor, which is 5.

5/30 ÷ 5/5 = 1/6

Therefore, the fraction in lowest terms that shows how many students liked country is 1/6.

Answer:

1. x = 11

2. x = -1

3. s = 1

4. c = 12

5. r = 9

6. x = 10

7. b = 6

8. c = 6

9. y = 2

10. d = 7

11. L = 2

12. k = 24

13. p = 18

14. s = 6

15. a = 12

Answer:

1. 4(x -3) = 32

4x - 12 = 32

4x = 32 - 12

4x = 20

4x /4 = 20 /4

x = 5

2 . 12 ( 2x + 4 ) = 24

24x + 48 = 24

24x = 24 - 48

24x = - 24

Divide both sides by 24

x = - 1

3. 3 ( 3s + 4) = 24

9s + 12 = 24

9s = 24 - 12

9s = 12

9s = 12

Divide both sides by 9

s = 12 /9

4. 3 ( c - 2 ) = 2 ( c +3 )

3c - 6 = 2c + 6

3c - 2c = 6 + 6

c = 12

5 . 12(r - 3 )= 6 (r + 3)

12r - 36 = 6r + 18

12r - 6r = 18 + 36

6r = 54

Divide both sides by 6

r = 9

6 . 2 ( x + 5 ) = 30

2x + 10 = 30

2x = 30 - 10

2x = 20

x = 10

The chromatic number of the graph K33, which is a complete bipartite graph with 33 vertices, each connected to every vertex in the other set, is 2. This means that the graph can be colored using only two colors.

The chromatic number of a graph represents the minimum number of colors needed to color its vertices such that no adjacent vertices have the same color.

In the case of K33, the graph is a complete bipartite graph, which means it can be divided into two sets of vertices, where each vertex in one set is connected to every vertex in the other set. In this specific graph, we have 33 vertices in each set.

To determine the chromatic number, we observe that in a complete bipartite graph, no vertices within the same set are connected to each other. Therefore, we can assign one color to all the vertices in one set and a different color to all the vertices in the other set.

In K33, we can color one set of 33 vertices, let's say set A, with color 1, and the other set of 33 vertices, set B, with color 2. Since no vertices within the same set are connected, there will be no adjacent vertices with the same color.

Hence, we conclude that the chromatic number of the graph K33 is 2, as it can be colored using only two colors.

296 hot lunches were sold on Friday.

The number of hot lunches sold on Friday can be calculated by multiplying the total number of hot lunches by the relative frequency on Friday:

Hot lunches sold on Friday = 1,350 * 0.22 = 296

Relative frequency is a measure of the number of times an event occurs in a sample, expressed as a proportion of the total number of events. To find the number of hot lunches sold on Friday, we multiply the total number of hot lunches sold in the week by the relative frequency of Friday. This gives us the number of hot lunches sold on Friday, which is 296 in this case. Understanding relative frequency is important in statistics as it helps to summarize data and understand the distribution of events.

The values of x and y in the intersecting lines are as follows;

When parallel lines are cut by a transversal line angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.

Therefore, the angle relationships can be used to find the value of x and y in the intersecting lines.

6y + 14 = 11y - 16 (vertically opposite angles)

Vertically opposite angles are congruent.

6y - 11y = - 16 - 14

-5y = -30

y = -30 / -5

y = 6

Therefore,

13x - 25 + 11y - 26 = 180 (sum of angles on a straight line)

13x - 25 + 66 - 26 = 180

13x = 180 + 25 - 66 + 26

13x = 165

x = 165 / 13

We note that the quadratic can be factored into \((2x-1)(x-1)\).

The quadratic is greater than \(0\) if both of its factors are positive, or they are both negative.

Case: both positive

We need to solve the system of inequalities:

\(2x-1>0\\x-1>0\).

The first inequality gives \(x>\frac{1}{2}\).

The second inequality gives \(x>1\).

Taking the points where the inequalities coincide gives \(x>1\).

(Note: 1 is a root of the quadratic. Coincidence? If not, try and prove it!)

Case: both negative

We need to solve the system of inequalities:

\(2x-1<0\\x-1<0\).

The first inequality gives \(x<\frac{1}{2}\).

The second inequality gives \(x<1\).

Taking the points where the inequalities coincide gives \(x<\frac{1}{2}\).

(Note: \(\frac{1}{2}\) is the other root of the quadratic. Coincidence? If not, try and prove it!)

Taking the union of both cases gives the solution set: \(\boxed{x\in (-\infty, \frac{1}{2}) \cup (1, \infty)}\)

2)

We bring over the \(15\) to get \(x^2-2x-15<0\).

Note that the quadratic factors into \((x-5)(x+3)\).

The quadratic is less than \(0\) if 1 of its factors is negative, but not both.

Case: first factor is negative, second positive

We have that \(x-5<0\) and \(x+3>0\).

We get that \(x<5\) and \(x>-3\), which has the solution set \(-3<x<5\).

Case: second factor is negative, first positive

We have that \(x+3<0\) and \(x-5>0\).

We get that \(x<-3\) and \(x>5\), which has no solutions.

So, the solution set is \(\boxed{x\in (-3, 5)}\)

No, the presence of an effect does not necessarily imply that error variance will go away.

The presence of an effect does not necessarily imply that error variance will go away. In fact, error variance is an inherent part of any statistical model and represents the amount of variation in the response variable that is not explained by the predictor variables.

Even if a predictor variable has a significant effect on the response variable, there may still be some unexplained variation in the response that is attributable to error variance.

It is important to take into account and control for error variance in any statistical analysis, as it can affect the precision and accuracy of the estimates of the model parameters and can also influence the interpretation of the results.

One way to control for error variance is to use appropriate statistical methods, such as analysis of variance (ANOVA), regression analysis, or other modeling techniques that take into account the variability in the data.

Incommensurable magnitudes refer to two quantities or lengths that cannot be expressed as a ratio of integers.

In other words, there is no common measure or common unit that can evenly divide both magnitudes. This concept dates back to ancient Greek mathematics and was explored extensively by mathematicians such as Euclid and Pythagoras.

The use of irrational numbers in geometry is closely related to the idea of incommensurability. Irrational numbers are numbers that cannot be expressed as a fraction or a ratio of integers and have non-terminating, non-repeating decimal expansions.

To find the angle of elevation, we need to determine the height of the plane relative to the trees, and then use the tangent function to find the angle. Let's call the height of the plane "h".

We can set up a right triangle with the height of the plane, the distance from the runway to the trees, and the height of the trees.

We have:

h / (150 + 75) = 100 / h

Solving for h, we find that:

h = 125

So the height of the plane relative to the trees is 125 feet.

Now we can use the tangent function to find the angle:

tan(angle) = 100 / 125

angle = tan^-1(100 / 125)

angle = approximately 53.13 degrees

Rounding to the nearest hundredths, the angle of elevation that the pilot must take to avoid crashing into the trees is 53.13 degrees.

The minimum hot-holding temperature for fried shrimp is d. 135 ° F 57 ° C. It is important to maintain this temperature to ensure that the food remains safe for consumption and to prevent the growth of harmful bacteria.

The minimum hot-holding temperature for fried shrimp is 135 °F (57 °C). When food is hot-held, it means it is kept at a specific temperature after cooking to maintain its quality and safety until it is served or consumed. This temperature is important because it helps prevent the growth of harmful bacteria, such as Salmonella and E. coli, that can cause food borne illnesses.

At a hot-holding temperature of 135 °F (57 °C) or higher, the heat inhibits the growth of bacteria, ensuring that the fried shrimp remains safe for consumption. This temperature range is considered a critical control point in food safety practices.

It's worth noting that the temperature of 135 °F (57 °C) is the minimum requirement for hot-holding fried shrimp. However, in practice, it's generally recommended to hold the shrimp at a slightly higher temperature to account for any temperature loss that may occur over time.

Some food establishments may set their hot-holding equipment to maintain a temperature of 140 °F (60 °C) or higher to ensure the safety and quality of the food.

By adhering to proper temperature control guidelines, including maintaining the minimum hot-holding temperature of 135 °F (57 °C), you can help prevent the risk of food borne illnesses and ensure that the fried shrimp remains safe and enjoyable to consume.

The worth of the horse is 1800 dollars

Given that a cowboy worked for one year for 19,200 plus a horse.

After 7 months, he quit and was paid 10,450 but got to keep the horse.

We need to find the worth of the horse.

Here, the horse is part of the payment in total, so it has to be used as a variable when setting up the proportion.

Let us consider the net worth of the horse to be H

solving for H,

[19,200 + H] / 12 = [10,450 + H] / 7

Now, cross multiply

134,400 + 7H = 125,400 + 12H

134,400 - 125,400 = 12H - 7H

9,000 = 5H

H = 9,000 / 5

H = $1,800

Hence, the net worth of the horse, H is $1,800.
