To estimate the minimum sample size required to estimate the population mean with a 95% confidence level and a desired margin of error, we can use the formula:

n = (Z * σ / E)²

Where:

n = sample size

Z = Z-score corresponding to the desired confidence level

σ = population standard deviation

E = desired margin of error

In this case, the desired confidence level is 95%, so the corresponding Z-score is the critical value associated with a 95% confidence level. From standard normal distribution tables, the Z-score for a 95% confidence level is approximately 1.96.

Given that the population standard deviation is 1.6 hours and the desired margin of error is 25 hours, we can plug in these values into the formula:

n = (1.96 * 1.6 / 25)²

Simplifying the equation:

n = (0.3136 / 25)²

n = 0.0125²

n ≈ 0.00015625

To find the minimum sample size, we need to round up to the nearest whole number since the sample size must be a whole number:

n ≈ 1

Therefore, the minimum sample size required to estimate the population mean with 95% confidence and a margin of error of 25 hours is approximately 1.

It is important to note that a sample size of 1 is not practically feasible or reliable for making statistical inferences. This result suggests that there may be other factors or considerations that need to be taken into account to determine a suitable sample size for this particular study.

The weight of the new player is 9 kg.

Given -

Mean weight of the team before including the new player = 86.5 kg

Mean weight of the team after including the new player = 86 kg

Number of players in the team before including the new player = 18

To find -

The weight of the new player

Solution -

Let's denote the weight of the new player as 'x' kg.

To solve the problem, we'll use the formula for the mean:

Mean = (Sum of all values) / (Number of values)

The sum of weights of the original 18 players = 86.5 kg * 18

The sum of weights of all 19 players = (86 kg * 18) + x kg

According to the problem, the mean weight before including the new player is 86.5 kg, and the mean weight after including the new player is 86 kg. So, we can set up the following equation:

(86.5 kg * 18) = (86 kg * 18) + x kg

Now, let's solve the equation to find the weight of the new player:

(86.5 kg * 18) = (86 kg * 18) + x kg

1557 kg = 1548 kg + x kg

9 kg = x kg

Therefore, the weight of the new player is 9 kg.

Area of a Segment of a Circle = θ/360° × πr2 – ½ r2sinC

PLEASE MARK AS BRAINLIEST

Answer:

[tex]AB=2r\sin\left(\dfrac{m\overset\frown{AB}}{2}\right)[/tex]

Step-by-step explanation:

Label the center of the circle O.

If two line segments are drawn from the center of the circle to points A and B on the circumference, an isosceles triangle will be formed, where the legs OA and OB are the radius, r, and the base is chord AB.

If an angle bisector is drawn from the center of the circle to the midpoint of AB, the isosceles triangle is divided into two right triangles.

An equation can now be formed for the base of the right triangle (half the length of chord AB), by using the sine trigonometric ratio.

The angle is half the central angle AOB, the side opposite the angle is half the chord AB, and the hypotenuse is the radius, r. Therefore:

                [tex]\sin (\theta)=\dfrac{\sf opposite\;side}{\sf hypotenuse}[/tex]

[tex]\sin\left(\dfrac{m\angle AOB}{2}\right)=\dfrac{\frac{1}{2}AB}{r}[/tex]

Rearrange the equation to isolate AB:

[tex]\dfrac{1}{2}AB=r\sin\left(\dfrac{m\angle AOB}{2}\right)[/tex]

[tex]AB=2r\sin\left(\dfrac{m\angle AOB}{2}\right)[/tex]

Since the measure of an arc is equal to the measure of its corresponding central angle, this means that [tex]m\overset\frown{AB}=m \angle AOB[/tex]. Therefore, the equation to find the length of chord AB given the measure of arc AB is:

[tex]\boxed{AB=2r\sin\left(\dfrac{m\overset\frown{AB}}{2}\right)}[/tex]

Note: We would also need to know the length of the radius, r.

Calculating 384 yd^2 and 1057 yd^2. expression, we find that the volume of the smaller solid is approximately 493.6 yd^3 when rounded to the nearest unit.

The surface areas of two similar solids are given as 384 yd^2 and 1057 yd^2. Let's denote the surface area of the smaller solid as SA_small and the surface area of the larger solid as SA_large.

We know that the surface area of a solid is proportional to the square of its linear dimension (length, width, or height) in similar solids. Therefore, the ratio of the surface areas is equal to the square of the ratio of their corresponding linear dimensions.

Using this concept, we can set up the following proportion:

(SA_small / SA_large) = (V_small / V_large)^2

Plugging in the given values, we have:

384 / 1057 = (V_small / 1795)^2

Simplifying further:

0.363 = (V_small / 1795)^2

The mean is the most sensitive to extreme scores, followed by the median, while the mode is the least affected. The mean is greatly influenced by outliers, the median is moderately influenced, and the mode is generally unaffected by extreme scores.

The mean, median, and mode are measures of central tendency used to describe the average or typical value in a dataset. They differ in their sensitivity to extreme scores, also known as outliers or extreme values.

Mean:

The mean is calculated by summing all the values in a dataset and dividing by the total number of values. It is highly sensitive to extreme scores because it takes into account the magnitude of each value. Even a single extreme score can significantly affect the mean. This sensitivity arises from the fact that the mean incorporates all values in the dataset. Therefore, outliers can distort the mean and pull it towards their direction

Median:

The median represents the middle value when the dataset is arranged in ascending or descending order. It is less sensitive to extreme scores compared to the mean. The median only considers the position of the values, not their actual values. Therefore, extreme scores have less impact on the median since it focuses on the relative position of values rather than their magnitude. As a result, outliers have minimal influence on the median.

Mode:

The mode represents the value(s) that appear most frequently in the dataset. Like the median, the mode is not significantly affected by extreme scores. Outliers can occur in a dataset without affecting the mode because the mode is determined by the most frequently occurring value(s), regardless of their magnitude. In datasets with multiple modes or no mode, extreme scores may not significantly impact the mode.

Answer:

(x - 9)^2 + (y + 5)^2 = 50.

Step-by-step explanation:

To determine the equation of the circle with a center at (9, -5) and containing the point (10, 2), we need to find the radius of the circle first. The radius is the distance between the center and any point on the circle, such as (10, 2).

We can use the distance formula to find the radius:

r = √((x2 - x1)^2 + (y2 - y1)^2)

Substituting the given values:

r = √((10 - 9)^2 + (2 - (-5))^2)

Simplifying:

r = √(1^2 + 7^2)

r = √(1 + 49)

r = √50

Simplifying further:

r = √(25 * 2)

r = 5√2

Now that we have the radius, we can write the equation of the circle in standard form:

(x - h)^2 + (y - k)^2 = r^2

Substituting the values:

(x - 9)^2 + (y - (-5))^2 = (5√2)^2

Simplifying:

(x - 9)^2 + (y + 5)^2 = 50

Therefore, the equation of the circle with a center at (9, -5) and containing the point (10, 2) is:

(x - 9)^2 + (y + 5)^2 = 50.

f(g(x)) = x + 11 + 2√x and g(f(x)) = √(x² + 5) + 6. These are the simplified expressions for f(g(x)) and g(f(x)) using the given pair of functions.

To find f(g(x)), we substitute g(x) into the function f(x) and simplify:

f(g(x)) = f(√x + 6)

Since f(x) = x² + 5, we have:

f(g(x)) = (√x + 6)² + 5

= (x + 6 + 2√x) + 5

= x + 6 + 2√x + 5

= x + 11 + 2√x

Therefore, f(g(x)) simplifies to x + 11 + 2√x.

To find g(f(x)), we substitute f(x) into the function g(x) and simplify:

g(f(x)) = g(x² + 5)

Since g(x) = √x + 6, we have:

g(f(x)) = √(x² + 5) + 6

There is no further simplification possible for g(f(x)).

(i) The probability that none of the 11 patients will have the mild side effect can be calculated using the binomial distribution.

In this case, the probability of an individual patient having the side effect is 6% or 0.06, and the probability of not having the side effect is 1 - 0.06 = 0.94.

The probability that none of the 11 patients will have the side effect can be calculated as:

P(X = 0) = (0.94)^11 ≈ 0.5147

So, the probability that none of the patients will have the mild side effect is approximately 0.5147 or 51.47%.

(ii) The probability that at least one patient will have the mild side effect can be calculated as the complement of the probability that none of the patients will have the side effect.

In other words, it is 1 minus the probability of none of the patients having the side effect.

P(at least one patient has the side effect) = 1 - P(X = 0) = 1 - 0.5147 ≈ 0.4853

So, the probability that at least one patient will have the mild side effect is approximately 0.4853 or 48.53%.

(i) To find the probability that none of the patients will have the mild side effect, we use the binomial distribution formula.

The probability of success (having the side effect) is given as 0.06, and the probability of failure (not having the side effect) is 1 - 0.06 = 0.94.

We raise the probability of not having the side effect to the power of the number of trials (11 patients) to find the probability that none of them will have the side effect.

(ii) To find the probability that at least one patient will have the mild side effect, we use the complement rule.

The complement of none of the patients having the side effect is at least one patient having the side effect.

By subtracting the probability of none of the patients having the side effect from 1, we find the probability of at least one patient having the side effect.

These probabilities are important in assessing the likelihood of experiencing the mild side effect when using the new drug.

The given statement presents a contradiction in the assumption by assuming the existence of a well-ordered set and an increasing function, and shows that the function's value is always less than the input element in the set.

The given statement is a part of a proof demonstrating a property of an increasing function on a well-ordered set. Here's an explanation in 150 words:

The statement assumes that we have a well-ordered set W, equipped with a strict total order "<." Additionally, we have a function f defined on the set of all elements of W to W itself. The function f is said to be increasing, meaning that for any x and y in W, if x < y, then f(x) < f(y).

The proof aims to show that for every element x in W, f(x) is always less than x. To do this, it considers the set X, which contains all elements x in W such that f(x) < x. The assumption is made that X is nonempty and let z be the least element of X.

Then, the proof considers the element w = f(z), and it aims to reach a contradiction. It assumes that w is greater than f(z), i.e., f(w) < w. This leads to a contradiction because it contradicts the definition of X, where x should be in X if f(x) < x.

Di. R is not a partial ordering relation, a Hasse diagram cannot be drawn. ii. There are no equivalence classes to find.

To determine whether the relation R is an equivalence relation or a partial ordering relation on the set N = {1, 2, 3, 4, ...}, examine its properties.

a. Reflexivity:

For a relation to be reflexive, every element in the set should be related to itself. In the given definition of R, we have x = y¹, where y¹ represents the first power of y. Since any number raised to the power of 1 is equal to itself, the relation R is reflexive.

b. Symmetry:

For a relation to be symmetric, if x is related to y, then y should also be related to x. In the given definition of R, we have x = y¹. This relation is not symmetric because if x = 2 and y = 3, then x = y¹ is not satisfied.

c. Transitivity:

For a relation to be transitive, if x is related to y and y is related to z, then x should be related to z. In the given definition of R, we have x = y¹. This relation is not transitive because if x = 2, y = 3, and z = 4, then x = y¹ and y = z¹ are satisfied, but x = z¹ is not satisfied.

Based on the above analysis, we can conclude that the relation R is neither an equivalence relation nor a partial ordering relation on the set N = {1, 2, 3, 4, ...}.

d. Since the relation R is neither an equivalence relation nor a partial ordering relation on the set N = {1, 2, 3, 4, ...}, the Hasse diagram cannot be drawn, as it is applicable only for partial ordering relations.

i. Given that R is not a partial ordering relation, a Hasse diagram cannot be drawn.

Answer:

28,45,53 is a Pythagorean Triple

Step-by-step explanation:

To determine whether 28, 45, and 53 form a Pythagorean triple, we need to check whether they satisfy the Pythagorean theorem, which states that for any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

So, we need to check whether:

28^2 + 45^2 = 53^2

Evaluating the left-hand side of the equation, we get:

784 + 2025 = 2809

And evaluating the right-hand side of the equation, we get:

2809 = 2809

Since both sides are equal, we can conclude that 28, 45, and 53 form a Pythagorean triple, because they satisfy the Pythagorean theorem. Therefore, 28^2 + 45^2 = 53^2 is a true statement, and we can say that the lengths 28, 45, and 53 can form the sides of a right triangle.

Let's assume the woman invested x dollars in the account that pays 11% per year.

Since she invested a total of $8000, the amount invested in the account that pays 12% per year would be (8000 - x) dollars.

Now, let's calculate the interest earned from each investment:

Interest from the 11% account: 0.11x

Interest from the 12% account: 0.12(8000 - x)

According to the given information, the total interest earned in the first year is $910. Therefore, we can set up the following equation:

0.11x + 0.12(8000 - x) = 910

Let's solve this equation to find the value of x:

0.11x + 0.12 * 8000 - 0.12x = 910

0.11x - 0.12x = 910 - 0.12 * 8000

-0.01x = 910 - 960

-0.01x = -50

Dividing both sides by -0.01:

x = (-50) / (-0.01)

x = 5000

Therefore, the woman invested $5000 in the account that pays 11% per year.

The amount invested in the account that pays 12% per year would be 8000 - 5000 = $3000.

So, she invested $5000 in the 11% account and $3000 in the 12% account.

Path A-B-C-E represents the distance traveled, which is 18 meters.

Path A-G-C-E represents the displacement, which is 17 meters.

From the given figure, we can identify the paths and calculate the distance and displacement.

Path A-B-C-E represents the distance traveled, and path A-G-C-E represents the displacement.

Let's calculate the lengths of both paths:

Distance traveled (Path A-B-C-E):

Length of AB = 9m

Length of BC = 3m

Length of CE = 6m

Total distance traveled = Length of AB + Length of BC + Length of CE

Therefore, the distance traveled along path A-B-C-E is 18 meters.

Displacement (Path A-G-C-E):

Length of AG = 5m

Length of GC = 6m

Length of CE = 6m

Total displacement = Length of AG + Length of GC + Length of CE

= 5m + 6m + 6m

= 17m

Therefore, the displacement along path A-G-C-E is 17 meters.

c) The tangent lines to the curve where the slope is 8 are y = 8x - 10 and y = 8x + 14.

a) To find the equation of the line perpendicular to the tangent line at the point (2,6), we first need to determine the slope of the tangent line. The derivative of the curve y=x^3-4x+6 is y' = 3x^2 - 4. Evaluating the derivative at x = 2 gives y'(2) = 3(2)^2 - 4 = 8.

Since the line perpendicular to the tangent line has a slope that is the negative reciprocal of the tangent line's slope, the slope of the perpendicular line is -1/8. Using the point-slope form of a linear equation with the given point (2,6), we have y - 6 = (-1/8)(x - 2). Simplifying, we get y = (-1/8)x + 7/4 as the equation of the perpendicular line.

b) To find the smallest slope on the curve, we can take the derivative and set it equal to zero. Differentiating y=x^3-4x+6, we have y' = 3x^2 - 4. Setting y' equal to zero, we get 3x^2 - 4 = 0. Solving for x, we find x = ±sqrt(4/3). The smallest slope occurs at the point where x = -sqrt(4/3) since the curve is concave up at this point. Evaluating y at this x-value, we have y = (-sqrt(4/3))^3 - 4(-sqrt(4/3)) + 6, which simplifies to y = 4 - 4sqrt(4/3) + 6 = 10 - 4sqrt(4/3).

c) To find the equations of the tangent lines where the slope of the curve is 8, we set the derivative equal to 8 and solve for x. 3x^2 - 4 = 8. Simplifying, we get 3x^2 - 12 = 0. Factoring, we have 3(x^2 - 4) = 0, which gives us x = ±2. Evaluating y at these x-values, we find y = 2^3 - 4(2) + 6 = 2 and y = (-2)^3 - 4(-2) + 6 = -2.

Therefore, the equations of the tangent lines to the curve where the slope is 8 are y = 8x - 10 and y = 8x + 14.

5x + 3y = 13 ------> y = (-5/3)x + 13/3 ------> slope -5/3

This line is parallel

6x - 10y = 7 ------> y = (6/10)x - 7/10 = (3/5)x -7/10 ------> slope 3/5

Since (-5/3)(3/5) = -1 this line is perpendicular.
