Answer:

This shape is a rectangle so that means that the angles are 90°. From sum of angles of a triangle, x + 3x + 10 + 90 = 180 which means 4x + 100 = 180 → 4x = 80 → x = 20°.

The diaphragm creates a transverse section between the thoracic and abdominal body cavities.

The diaphragm is one of the important muscle involved in respiration, or breathing. It is a dome-shaped muscle is found just beneath the lungs and heart. It constantly contracts as you breathe in and out.

Thoracic diaphragm is the diaphragm which is present in the thorax and serves as an important anatomical landmark.

It acts as a separation between  the thorax, or chest, from the abdomen.

It contracts to enlarge the thoracic cavity and reduce the intrathoracic pressure so that lungs may expand and fill their alveoli with air during respiration.

Answer:

3 more balloons she has popped in the second game.

Step-by-step explanation:

Given that,

Total no. of balloons = 18

Amy popped 2/3 the first game and 5/6 the second game.

Balloons popped in first game = \(\dfrac{2}{3}\times 18=12\ \text{balloons}\)

Balloons popped in second game = \(\dfrac{5}{6}\times 18=15\ \text{balloons}\)

Difference of balloons popped in first and second game,

= 15-12

= 3 balloons

Hence, 3 more balloons she has popped in the second game.

An implementation of the `Point` class in Java with a `distance` method:

public class Point {

   private double x;

   private double y;

   public Point(double x, double y) {

       this.x = x;

       this.y = y;

   }

   public double distance(Point target) {

       double deltaX = this.x - target.x;

       double deltaY = this.y - target.y;

       return Math.sqrt(deltaX * deltaX + deltaY * deltaY);

   }

   public static void main(String[] args) {

       Point p1 = new Point(2.5, 3.8);

       Point p2 = new Point(1.0, 4.2);

       double distance = p1.distance(p2);

       System.out.println("The distance between p1 and p2 is: " + distance);

   }

}

In this implementation, the `Point` class has private attributes `x` and `y` to store the coordinates. The constructor `Point(double x, double y)` is used to initialize the point with the given coordinates.

The `distance` method takes another `Point` object as a parameter and calculates the distance between the current point and the target point using the distance formula. It returns the computed distance.

In the `main` method, we create two `Point` objects `p1` and `p2` with different coordinates. We then call the `distance` method on `p1` with `p2` as the target point and print the result.

This allows you to test the `Point` class and verify the correctness of the `distance` method.

Step-by-step explanation:

The multiplication rule of probability is used to calculate the joint probability of two events.

This rule states that the probability of two events occurring together is equal to the probability of one event occurring, multiplied by the probability of the other event occurring, given that the first event has already occurred.

In mathematical terms, this can be written as P(A and B) = P(A) * P(B|A), where P(A) is the probability of event A occurring, P(B|A) is the probability of event B occurring given that event A has already occurred, and P(A and B) is the joint probability of events A and B occurring together.

The multiplication rule is used to calculate the probability of two events occurring together when the events are dependent on each other.

Answer:

Selling price with VAT {15%} = Rs 41400

S.P +15% of S.P =Rs 41400

S.P(1+15%)=Rs 41400

S.P=Rs 41400/1.15

Selling price without VAT =Rs 36000

Again

Discount = 10%

M.P =S.P+ Discount % of M.P

M.P-Discount% of M.P= S.P

M.P(1-Discount%)=Rs 36000

M.P(1-10%)=Rs 36000

M.P=Rs 36000/0.9

Marked Price = Rs 40,000

again

Discount =Discount % of M.P

=10% of 40000

=Rs 4,000

Again

Profit=20%

For 20% profit

Cost price = (S.P*100)/(100+profit%)

=(36000*100)/(100+20)

= Rs 30000

For 24% profit

selling price = (100+profit%)*C.P/100

=(100+24)*30000/100

=Rs 37200

Again

Discount = 40000–37200 = Rs2800

Discount % = discount/M.P*100%

=2,800/40,000* 100 = 7%

Finally

Discount percent to be reduced =10%–7%= 3%

In the context of your experiment comparing the effectiveness of two treatments using a randomized block design, the following must be true:

1. The subjects are divided into two blocks based on their age: under 40 years and 40 years or older.
2. Randomization is used within each block to assign subjects to one of the two treatments. This ensures that each treatment group within a block has a random mix of subjects, reducing potential biases.
3. The purpose of blocking by age is to control for any confounding variables or potential effects that age might have on the treatment outcomes. By blocking, researchers can more accurately measure the differences between the two treatments.
4. The experiment is well-designed, which means it should minimize potential sources of error, include sufficient sample size, and ensure proper randomization and data collection.
5. To analyze the results, researchers will compare the treatment outcomes within each age block and then combine the results to get an overall measure of the effectiveness of the two treatments.

By using a randomized block design in this experiment, researchers can control for age-related factors and obtain a more accurate comparison of the treatment effectiveness.

1.) CIRCLE B

2.) 14 cm ; 7cm ; 154cm²

Step-by-step explanation:

Given that:

CIRCLE A:

Diameter (d) = 9cm

CIRCLE B:

Radius (r) = 5cm

Circumference of circle A:

Radius (r) = diameter / 2

C = 2 * pi * r = 2 * 3.14 * (9/2) = 28.26 cm

Circumference of Circle B:

C = 2 * pi * r = 2 * 3.14 * 5 = 31.4 cm

CIRCLE B has the larger Circumference.

2.) circle with Circumference (C) = 44cm

Diameter of circle ;

C = 2 * pi * (d/2)

44 = 2 * 3.14 * (d/2)

44 = 6.28d / 2

88 = 6.28d

d = 14.01 = 14.0 cm ( 1 decimal place)

B.) Circle's Radius

Radius = diameter / 2

Radius = 14.0 / 2 = 7 cm

C.) Area (A) of the circle :

A = pi * r^2

A = 3.14 * 7^2

A = 3.14 * 49

A = 153.86

A = 154 cm²

The probability of a single birth resulting in a girl if the probability of a single birth resulting in a boy is 51% is 49%

Probability is the measure of the likelihood of an event occurring. The probability of an event occurring ranges from 0 to 1. If an event is impossible, the probability of its occurrence is 0, and if the event is certain to occur, the probability is 1. The probabilities of the complement of an event equal one minus the probability of the event. For instance, the probability of the complement of an event A, denoted as A', is 1 - P(A). If the probability of an event A is P(A), then the probability of the complement of A is 1 - P(A).

Here, the probability of a single birth resulting in a boy is 51%. Therefore, the probability of a single birth resulting in a girl is the complement of this event, which is 49%. Hence, the main answer is that the probability of a single birth resulting in a girl if the probability of a single birth resulting in a boy is 51% is 49%.

The third quartile in a box-and-whisker plot represents the score below which 75% of the data falls. It is a measure of central tendency.

In a box-and-whisker plot, the third quartile (also known as the upper quartile or Q3) represents the score below which 75% of the data falls. It is a measure of central tendency that indicates the boundary between the highest 25% and the lowest 75% of the scores. To determine the third quartile, follow these steps:

1. Order the scores from smallest to largest.

2. Divide the data into two halves: the lower half and the upper half.

3. Locate the median of the upper half, which is the value where 50% of the data falls above and 50% falls below.

4. This value is the third quartile and represents the score below which 75% of the data falls.

The third quartile provides insights into the performance of students on the math test, indicating the score that is relatively higher than most of the scores achieved.

Answer:y is 60 slope is -10

Step-by-step explanation:

The correct hypothesis statement for this golfer to prove his claim would be:

\(H_{0} :u\geq 90\)

\(H_{1} :u < 90\)

The golfer claims that his average score is less than 90.

Therefore, the null hypothesis is the opposite of what he claims

Null hypothesis \(H_{0}\) is average score \(u\) is greater than or equal to 90:

\(u \geq 90\)

\(H_{0} :u\geq 90\)

Alternative hypothesis \(H_{1}\) is then the opposite of null hypothesis.

Hence alternate hypothesis \(H_{1}\) is u< 90
