Answer:

To find out how many points Nicky needs to score in her next game, we can use the formula for the mean (also known as the average) of a set of numbers:

mean = (sum of all numbers) / (number of numbers)

We know that Nicky has played three games and scored, and points in them. So the sum of all her points is:

sum=18+22+28

sum=68

We also know that Nicky wants to have a mean of 25 points per game, and she has played three games already. If we add the score from her next game to the sum, we will have the total number of points she has scored in four games.

The calculated value of the dividend yield on Stock A is 2%.

The dividend yield is a ratio that indicates how much a company pays out in dividends relative to its stock price.

To calculate the dividend yield on Stock A, we need to divide the annual dividend per share by the stock price per share and then multiply by 100 to express it as a percentage.

Annual dividend per share = Quarterly dividend per share x 4

Annual dividend per share = $0.10 x 4 = $0.40

Now, we can calculate the dividend yield on Stock A:

Dividend yield = Annual dividend per share / Stock price per share x 100%

Dividend yield = $0.40 / $20 x 100%

Dividend yield = 2%

Therefore, the dividend yield on Stock A is 2%.

The probability that all four chosen balls are red is 14/6075.

Probability is a way to gauge how likely or unlikely something is to happen. It is a number between 0 and 1, where 0 denotes an improbable event and 1 denotes an inevitable one.

Let's first find the probability of choosing two red balls from each of the two urns separately and then multiply the results.

The probability of choosing two red balls from urn 1 is:

P(2 red balls from urn 1) = (7/10) * (6/9) = 7/15

Similarly, the probability of choosing two red balls from urn 2 is:

P(2 red balls from urn 2) = (2/10) * (1/9) = 1/45

And the probability of choosing two red balls from urn 3 is:

P(2 red balls from urn 3) = (5/10) * (4/9) = 2/9

Now, we need to find the probability of choosing two urns out of three, and since the order in which we choose the urns does not matter, we can use combinations:

Number of ways to choose two urns out of three = C(3, 2) = 3

Therefore, the probability of choosing two urns out of three is 3/3 = 1.

Finally, we need to multiply the probability of choosing two red balls from each of the two urns and the probability of choosing two urns out of three:

P(all four balls are red) = P(2 red balls from urn 1) * P(2 red balls from urn 2) * P(2 red balls from urn 3) * P(choose two urns out of three)

= (7/15) * (1/45) * (2/9) * 1

= 14/6075

Therefore, the probability that all four chosen balls are red is 14/6075.

There are 988 distinct ways to color the corners of the cube using three different colors up to a rotation of the cube.

To find the number of ways to color the corners of a cube using three different colors up to a rotation of the cube, we can use Burnside's Lemma.

Burnside's Lemma states that the number of distinct colorings is equal to the average number of colorings fixed by each symmetry of the cube.
There are 24 possible rotations of the cube.

We can classify these rotations into 4 categories:
Identity (1 rotation):

This rotation leaves the cube unchanged.

All [tex]3^8 = 6561[/tex] colorings are fixed under this rotation.
90-degree rotation around an axis through the centers of two opposite faces (6 rotations):

Each of these rotations leaves only 3 colorings fixed, one for each color.

Therefore, there are 6*3 = 18 fixed colorings.

180-degree rotation around an axis through the centers of two opposite faces (3 rotations):

Each of these rotations leaves [tex]3^4 = 81[/tex]colorings fixed.

So, there are 3*81 = 243 fixed colorings.
120-degree and 240-degree rotation around an axis through two opposite vertices (8+8 = 16 rotations): Each of these rotations leaves 3^2 = 9 colorings fixed.

Thus, there are 16*9 = 144 fixed colorings.

The minimum number of coin flips required to obtain a 98% confidence interval width of at most 0.15 is 188.

Hence option d is correct.

We'll use the formula for the confidence interval of a proportion, which is given by:
CI = p-hat ± (z * sqrt(p-hat * (1-p-hat) / n))
Here, p-hat represents the sample proportion (observed proportion of heads), z is the z-score for the desired confidence level (98% in this case), and n is the number of coin flips.
We want to find the minimum number of coin flips (n) needed to obtain a confidence interval width of at most 0.15. Since we suspect that the coin is fair, we'll assume p-hat = 0.5.
For a 98% confidence interval, the z-score (rounded to three decimal places) is 2.576.

Now, we'll set up the inequality:
0.15 >[tex]= 2 * (2.576 * \sqrt{(0.5 * (1-0.5) / n))}[/tex]
Squaring both sides and solving for n, we get:
n >= [tex]((2.576 * \sqrt{(0.25))^2) / (0.15/2)^2}[/tex]
n >= 188.423

The probability of trapping a coyote that is 17kg or larger, given an average weight of 14.5kg and a standard deviation of 4kg is approximately 0.2743 or 27.43%.

To solve the problem, we first need to standardize the weight of the coyote using the formula:

z = (x - μ) / σ

Where:

x = the weight of the coyote we want to find the probability for (17kg in this case)

μ = the population mean (14.5kg in this case)

σ = the population standard deviation (4kg in this case)

z = the standardized score

Substituting the given values in the formula, we get:

z = (17 - 14.5) / 4

z = 0.625

Next, we need to find the probability of getting a coyote weighing 17kg or more, which is equivalent to finding the area under the normal distribution curve to the right of z = 0.625. We can use a standard normal distribution table or a calculator to find this probability.

Using a calculator, we can use the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives the area under the curve to the left of a specified z-score. Since we want the area to the right of z = 0.625, we can subtract the CDF from 1 to get the area to the right.

Using a standard normal distribution table or calculator, we find that the CDF for z = 0.625 is approximately 0.734. Therefore, the area to the right of z = 0.625 is 1 - 0.734 = 0.266 or 26.6%.

Thus, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.

Using a standard normal distribution table or a calculator, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.

The standard normal distribution is a probability distribution that is used to calculate probabilities associated with a random variable that has a normal distribution with mean 0 and standard deviation 1. Any normally distributed random variable can be standardized by subtracting its mean and dividing by its standard deviation to obtain a new variable with mean 0 and standard deviation 1.

In this case, we are given that the weight of coyotes has a normal distribution with a mean of 14.5kg and a standard deviation of 4kg. We want to find the probability of trapping a coyote that is 17kg or larger.

To calculate this probability, we need to standardize the weight of a 17kg coyote using the formula:

z = (× - μ) / σ

where:

x is the value we want to standardize (in this case, 17kg),

μ is the mean of the distribution (14.5kg),

σ is the standard deviation of the distribution (4kg).

Substituting the values we have:

[tex]z =\frac{(17 - 14.5)}{4} = 0.625[/tex]

This value of 0.625 is the z-score for a coyote weighing 17kg. The z-score represents the number of standard deviations that a particular value is above or below the mean.

Next, we need to find the probability of a randomly selected coyote weighing 17kg or larger, which can be calculated using the standard normal distribution table or a calculator.

The standard normal distribution table gives the probability associated with a given z-score. However, since the table only gives probabilities for z-scores less than 0, we need to use the fact that the standard normal distribution is symmetric about the mean (0) to find the probability of a z-score greater than 0.625.

Specifically, we can use the property that:

P(Z > z) = 1 - P(Z < z)

where Z is a standard normal random variable and z is a z-score. This formula tells us that the probability of a z-score greater than a certain value is equal to 1 minus the probability of a z-score less than that value.

Using this formula, we can calculate:

P(Z > 0.625) = 1 - P(Z < 0.625)

We can look up the value of P(Z < 0.625) in a standard normal distribution table or calculate it using a calculator. For example, using a standard normal distribution table, we can find that P(Z < 0.625) = 0.734.

Substituting this value into the formula, we get:

P(Z > 0.625) = 1 - 0.734 = 0.266

Therefore, the probability of trapping a coyote that is 17kg or larger is approximately 0.266 or 26.6%.

The expression that represents the discounted price of the jacket is 0.7x. This means that the discounted price is 70% of the original price, or equivalently, that the discount reduces the price of the jacket by 30%.

What is original price?

In order to determine the sales price, the value of the discount would be subtracted from the original price.

When an item is offered at a discount, the discounted price is usually calculated by subtracting the discount from the original price. In this case, since the discount is 30%, we can find the amount of the discount by multiplying the original price x by 0.3. This gives us 0.3x, which is the amount of money that is being discounted from the original price. To find the discounted price, we subtract this amount from the original price, which gives us:

x - 0.3x = 0.7x

(b) One point: y = 2x - 1 (where the line intersects the parabola at (1,1))

(c) No point: y = 2x + 2 (the line does not intersect the parabola)

A parabola is a U-shaped symmetrical curve. In mathematics, it is a type of quadratic function that can be described as y = ax² + bx + c, where a, b, and c are constants and x is the variable. The graph of a parabola is symmetric about a vertical line called the axis of symmetry, which passes through the vertex of the parabola.

In the given question,

(a) When the graph of the line intersects the graph of the parabola at two points, it means that the discriminant of the quadratic equation is positive. Let the two intersection points be (x1, y1) and (x2, y2), where x1 < x2. Then we have:

y1 = x1² and y2 = x2²

The slope of the line passing through these two points is:

m = (y2 - y1)/(x2 - x1) = (x2² - x1²)/(x2 - x1) = x1 + x2

The equation of the line can then be written as:

y - y1 = m(x - x1)

y - x1^2 = (x1 + x2)(x - x1)

(b) When the graph of the line intersects the graph of the parabola at one point, it means that the discriminant of the quadratic equation is zero. Let the intersection point be (x0, y0), then we have:

y0 = x0^2

The equation of the line can be written as:

y - y0 = m(x - x0)

y - x0² = m(x - x0)

(c) When the graph of the line does not intersect the graph of the parabola, it means that the discriminant of the quadratic equation is negative. In this case, there is no solution for the system of equations y = x² and y = mx + b, where m and b are constants. Therefore, there is no equation of the line that satisfies this condition.

therefore the area of the semicircle is 56.52ft²

The area of a rectangle is expressed as;

A = l×w

= 19×12

= 228ft²

therefore the area of the rectangle is 228ft²

The total area = (228+56.52)ft²

= 284.52ft²

Step-by-step explanation:

you do rise over run which is 3 up and 2 over in this case. and the 0 is the y intercept but its at the center also known as the origin so its 0

Answer:

Step-by-step explanation:

"An integer is the number 0 or any number obtained by repeatedly adding 1 to this number" is not entirely true.

True that integers can be represented by repeatedly adding or subtracting the number 1,

The fact that integers can also be negative and can be obtained by repeatedly subtracting 1 from 0 or another negative integer.

The definition does not account for the fact that integers can be represented using other operations, such as multiplication or division. The integer 12 can be represented as 4 x 3 or as 24 ÷ 2.

A more accurate definition of an integer is a whole number that can be positive, negative, or zero.

Integers can be represented using addition, subtraction, multiplication, or division, and can be used to represent quantities such as counts, distances, temperatures, and other measurable quantities.

The original definition is a useful way to understand how integers can be represented using addition and subtraction, it is not a complete or entirely accurate definition of what integers are.

The length of the lake in miles for the given situation of travelling motor boat is equal to 9 miles.

Let us consider the length of the lake be d in miles.

Number of miles motor boat travelled per hour = 18 miles

When the motor boat travels at 18 miles per hour,

The time it takes to travel the length of the lake is,

t₁ = d/18

When the motor boat travels at 12 miles per hour,

The time it takes to travel the length of the lake is,

t₂ = d/12

Time it takes to travel the length of the lake at 18 miles per hour

=  one-quarter of an hour less than the time it takes at 12 miles per hour,

⇒ t₁ = t₂ - 1/4

Substituting the expressions for t₁ and t₂ from above, we get,

⇒ d/18 = d/12 - 1/4

Simplify this equation by multiplying both sides by the least common multiple of the denominators,

least common multiple = 36

⇒ 2d = 3d - 9

Solving for d, we get,

⇒ d = 9

Therefore, the length in miles of the lake is 9 miles.
