Shawna's new score can be represented by the equation is New Score = Current Score + (Result of Black Cube) + (Result of Red Cube). So, Shawna's new score is 2.

In the game that Shawna is playing, rolling the black cube results in a positive number, while rolling the red cube results in a negative number. We are told that Shawna's current score is 4, which means that she has accumulated 4 points up to this point in the game.

Next, we are told that Shawna rolls a red 5 and a black 3. This means that the red cube resulted in a negative 5 and the black cube resulted in a positive 3.

To calculate Shawna's new score, we can add the results of these two rolls to her current score. However, we need to be careful to subtract the negative number, rather than adding it. This is because a negative number is actually a decrease in score.

Therefore, we can use the following equation to calculate Shawna's new score:

New Score = Current Score + (Result of Black Cube) + (Result of Red Cube)

Substituting in the values that we know, we get:

New Score = 4 + 3 + (-5)

Simplifying, we can combine the positive and negative numbers:

New Score = 4 - 2

Therefore, Shawna's new score is 2. This means that after rolling a red 5 and a black 3, her score has decreased by 2 points from her original score of 4.

One serving of Christian's lemonade has 0.125 cups more water than one serving of Hayden's lemonade.

Lemonade is a sweetened beverage made from lemon juice, water, and sugar. It is typically served cold, and may also include other ingredients such as fruit, herbs, or carbonated water. Lemonade is a popular summer drink that is enjoyed in many parts of the world.

First, we can find the amount of water per serving in Hayden's lemonade by dividing the total amount of water (2.25 cups) by the number of servings (9 people):

Water per serving in Hayden's lemonade = 2.25 cups / 9 = 0.25 cups per serving

Next, we can find the amount of water per serving in Christian's lemonade by dividing the total amount of water (3.75 cups) by the number of servings (10 people):

Water per serving in Christian's lemonade = 3.75 cups / 10 = 0.375 cups per serving

To find how much more water is in one serving of Christian's lemonade compared to one serving of Hayden's lemonade, we can subtract the water per serving in Hayden's lemonade from the water per serving in Christian's lemonade:

Water per serving difference = 0.375 cups per serving - 0.25 cups per serving = 0.125 cups per serving

Therefore, one serving of Christian's lemonade has 0.125 cups more water than one serving of Hayden's lemonade.

We are told that the probability of drawing a red ball doubles when an extra 6 red balls are added.

Let's assume that there are initially "x" red balls in the box. This means that there are (12 - x) non-red balls in the box.

When 6 more red balls are added, the total number of red balls becomes (x + 6), and the total number of balls in the box becomes (12 + 6) = 18.

We are told that the probability of drawing a red ball doubles when an extra 6 red balls are added. This means that the probability of drawing a red ball before the extra balls were added was:

P(red) = x / 12

And the probability of drawing a red ball after the extra balls were added is:

P(red) = (x + 6) / 18

We are also told that the second probability is twice the first:

(x + 6) / 18 = 2 * (x / 12)

Simplifying this equation, we get:

(x + 6) / 9 = x / 6

Multiplying both sides by 18, we get:

2(x + 6) = 3x

Expanding the left-hand side, we get:

2x + 12 = 3x

Subtracting 2x from both sides, we get:

12 = x

Therefore, there are initially 12 red balls in the box.

By understanding what composite numbers are and how they relate to rolling a die, we can determine the expected number of times Ms. Rod will roll a composite number in 57 rolls.

A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words, a composite number is a number that can be factored into smaller positive integers.

To find the number of times Ms. Rod should expect to roll a composite number, we need to know how many numbers from 1 to 6 are composite. Only two numbers are prime in this range, namely 2 and 3. This means that the other four numbers (4, 5, and 6) are composite. Therefore, out of the 6 possible outcomes of rolling the die, 4 of them are composite numbers.

We can use this information to calculate the expected number of times Ms. Rod will roll a composite number. We know that she is rolling the die 57 times, and each roll has a probability of 4/6 (or 2/3) of resulting in a composite number. Therefore, we can use the formula for the expected value of a discrete random variable, which is:

Expected value = (number of trials) x (probability of success)

Plugging in the values, we get:

Expected value = 57 x 2/3

Expected value = 38

Therefore, we can expect Ms. Rod to roll a composite number about 38 times out of 57 rolls. However, it's important to note that this is just an expected value, and the actual number of times she rolls a composite number may vary.

The shape of the graph b will be linear with an immediate decrease in speed.

In Mathematics, a position vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled by an object from its starting position with respect to the time when it is started moving.

Generally speaking, the position or distance traveled by a physical object in a position vs time graph is always plotted on the y-coordinate while time is always plotted on the x-coordinate (x-axis).

In this scenario, the rate of change of the shape's position can be calculated as follows:

Rate of change = (30 - 50)/(40 - 30)

Rate of change = -20/10

Answer:

112.13 square mm

Step-by-step explanation:

Decompose the composite figure into familiar shapes. One such decomposition is shown in the attached figure

There are four familiar shapes

A semicircle and 3 rectangles

The diameter of the semicircle = 6 mm and therefore its radius is 3mm

Area of the semicircle = 1/2 x area of circle = 1/2 x π x 3²
= 1/2 x 3.14 x 9
= 14.13 square mm

The rectangle below the semi circle has height 5 mm and width 10 mm
Area of this rectangle= 5 x 10 = 50 square mm

The rectangle at the bottom left has width = 6 mm and height = 7mm
Area of this rectangle = 6 x 7 = 42 square mm

The bottom right rectangle has width 2 mm and height 3 mm
Area of this rectangle = 2 x 3 = 6 square mm

Area of the three rectangles = 50 + 42 + 6 = 98 square mm

Total area of composite figure

= Area of 3 rectangles + Area of semicircle

= 98 + 14.13

For small particles such as atoms and subatomic particles, quantum mechanics produces more accurate results than classical mechanics. As the particle size decreases, the differences between classical and quantum mechanical results become more pronounced.

The particle in an infinite square well potential is treated as a point particle with well-defined position and momentum in classical mechanics. The classical solution to the infinite square well problem involves a particle bouncing back and forth between the well's walls, its energy being provided by the kinetic energy associated with its motion inside the well.

In quantum mechanics, on the other hand, the particle in an infinite square well potential is treated as a wave function that solves the Schrödinger equation. The probability distribution of the particle's position and momentum inside the well is described by the wave function. The allowed energy levels of the particle are quantized and can be calculated using the problem's boundary conditions.

The following formula gives the classical result for a particle's energy in an infinite square well potential:

[tex]n2*h2/(8ma2) = E n[/tex]

where n is an integer, h is Planck's constant, and m is the particle's mass. According to this formula, energy levels are continuous and can take any value.

The quantum mechanical result for a particle's energy in an infinite square well potential, on the other hand, is given by the formula:

[tex]E n = (n2 * pi2 * h2) / (2ma2).[/tex]

n must be a positive integer. According to this formula, energy levels are quantized and can only take on discrete values.

As a result, the classical result for the energy of a particle in an infinite square well potential differs greatly from the quantum mechanical result. The classical result predicts continuous energy levels, whereas the quantum mechanical result predicts quantized energy levels.

In this scenario, the population refers to the entire group of students that the teacher is interested in studying. The population could be all students in the high school, all high school students within the country, all students in the class, or high school students in New York, depending on the research question.

A sample, on the other hand, is a smaller subset of the population that is actually observed or measured. The teacher selected 10 students from the front row as the sample for her study.

It's important to note that the accuracy of the conclusions drawn from a sample depends on how well the sample represents the population. In this case, the teacher may have concluded that the class did extremely well based on the scores reported by the 10 students in the front row. However, it's possible that the front row students are not representative of the entire class or the entire population, which could lead to inaccurate conclusions.

The combinations that are more affected by extreme observations are mean and standard deviation, while the combinations that are less affected are median and IQR.

The mean is more affected by extreme observations, because it takes into account the value of every observation in the data set, whereas the median only considers the middle value(s) and is therefore less sensitive to extreme values.

The standard deviation is more affected by extreme observations, because it takes into account the difference between each observation and the mean of the data set. A single extreme value can have a large impact on the mean, and therefore on the standard deviation.

On the other hand, the interquartile range (IQR) is less affected by extreme observations, because it only considers the range of the middle 50% of the data. The median and IQR are often used together to describe a data set that has extreme values or is not normally distributed.

The upper bound for the difference between the number of people at the football match and at the cricket match  is 29750<=p<=29849 .

p = number of people

The true value of p is unknown, but we know that it rounds to 29800 when rounding to the nearest hundred people.

The smallest p could be is 29750 since that rounds to 29800.

The largest is 29849; note that 29850 rounds to 29900.

We have this interval 29750<=p<=29849

r = the rate in which the people leave

This rate is in "people per minute".

Like p, the true value of r is unknown.

The midpoint of 350 and 400 is (350+400)/2 = 375, which represents the smallest value r could be if we round to the nearest 50.

The value 374 would round to 350.

On the other side of the spectrum, (400+450)/2-1 = 425-1 = 424 rounds to 400 as well when rounding to the nearest 50.

The value 425 rounds to 450.

To wrap this section up, you have this interval 375<=r<=424

Summary so far:

29750<=p<=29849

375<=r<=424

where p is the number of people and r is the rate in which they leave (in people per minute).

If we have the smallest number of people (29750) and the highest rate in which they leave (424), then we'll get the lower bound of how long it takes everyone to leave.

This can be thought of as the floor value.

time = (number of people)/(rate)

time = (29750)/(424)

time = 70.1650943396227

time = 70.165

Answer:

Step-by-step explanation:

Let x be the number of kangaroos adopted last year.

Twice the number adopted last year is 2x.

So, the number adopted this year is 2x - 24.

Equating this to the given number of kangaroos adopted this year, we have:

2x - 24 = 116

Adding 24 to both sides, we get:

2x = 140

Dividing both sides by 2, we get:

x = 70

So, the number of kangaroos adopted last year was 70.

As (-2, 2) and (4, -1) lie on a line the equation of the line is: y = (-1/2)x + 1

We can use the slope-intercept form of a linear equation,

which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope of the line using the two given points. The slope formula is:

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

where (x1, y1) and (x2, y2) are the coordinates of the two points.

Plugging in the values, we get:

m = (-1 - 2) / (4 - (-2)) = -3/6 = -1/2

Now we have the slope (m = -1/2), and we can use either of the two given points to find the y-intercept (b).

Let's use the first point (-2, 2):

y = mx + b

2 = (-1/2)(-2) + b

2 = 1 + b

b = 1
