Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.

A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.

Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

Therefore, the probability that exactly 4 out of 20 randomly chosen college students are near-sighted is closest to 0.7988 or approximately 0.80.

To find the probability that exactly 4 out of 20 randomly chosen college students are near-sighted, we can use the binomial probability formula.

The formula for the probability of k successes in n trials, with a probability of success p in each trial, is given by:

\(P(X = k) = (n choose k) * p^k * (1 - p)^{(n - k)\)

In this case, n = 20, k = 4, and p = 0.28 (probability of a student being near-sighted).

Plugging in these values into the formula, we get:

\(P(X = 4) = (20 choose 4) * (0.28)^4 * (1 - 0.28)^{(20 - 4)\)

Calculating the values:

(20 choose 4) = 4845

\((0.28)^4\) ≈ 0.006859

\((1 - 0.28)^{(20 - 4)\) ≈ 0.19224

P(X = 4) ≈ 4845 * 0.006859 * 0.19224

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:

tan(ACD) = CE / AB

tan(19) = CE / 100

CE = 100 * tan(19)

CE ≈ 34.5 m (rounded to 1 decimal place)

Therefore, the height of the clock tower is approximately 34.5 m.

Probability = number of favorable outcomes/number of total outcomes

In this scenario, we are concerned with the dart landing on the square. Thus,

number of favorable outcome = area of square

number of total outcome = area of circle

Area of square = s^2

where

s is the length of each side

Area of circle = πr^2

where

r is the radius of the circle

From the information given,

s = 6

r = 8

π = 3.14

Area of square = 6^2 = 36

Area of circle = 3.14 x 8^2 = 200.96

the probability that the dart lands in the shaded square region = 36/200.96

the probability that the dart lands in the shaded square region = 0.18

After 1 hour, the alcohol percentage of the beer in the tank will be approximately 5.62%. Initially, the tank contains 100 gallons of beer with 5% alcohol, resulting in 5 gallons of alcohol. The alcohol percentage is approximately 3.2/40 * 100 = 8%.

For every minute, 1 gallon of beer with 7% alcohol is pumped in, contributing 0.07 gallons of alcohol. At the same time, 2 gallons of beer are drained from the tank, resulting in a loss of 0.1 gallons of alcohol. After 60 minutes, a total of 60 gallons of 7% alcohol beer is pumped in, adding 4.2 gallons of alcohol. Meanwhile, 120 gallons of beer are drained out, removing 6 gallons of alcohol. Combining the initial alcohol content with the inflow and outflow, we find that the tank contains 100 + 60 - 120 = 40 gallons of beer after 1 hour, with 5 + 4.2 - 6 = 3.2 gallons of alcohol. Thus, the alcohol percentage is approximately 3.2/40 * 100 = 8%.

In conclusion, after 1 hour, the beer in the tank will have an alcohol percentage of approximately 5.62%. The calculation takes into account the initial alcohol content, the inflow rate of beer with higher alcohol percentage, and the outflow rate of the mixed beer. By considering the amounts of alcohol gained and lost during the hour, we determine that the tank will contain 40 gallons of beer with 3.2 gallons of alcohol. Dividing the alcohol content by the total volume of beer and multiplying by 100 yields the final alcohol percentage.

Step-by-step explanation:

it clearly consists of 2 rectangles and 1 triangle (as you tried correctly to point out by drawing the separating lines).

we only need to calculate all 3 areas and add them up for the total.

the area of a rectangle is

length × width

so, in our 2 cases we have

6 × 2 = 12 km²

5 × (3 + 2 + 3) = 5×8 = 40 km²

the area of a triangle is

baseline × height / 2

in case of a right-angled triangle the 2 sides enclosing the 90° angle can be used as baseline and height.

so, in our case

6 × (5 + 2 + (3 + 2 + 3 - 2)) / 2 = 6×(7 + 6)/2 = 3×13 = 39 km²

in total, the whole area is

12 + 40 + 39 = 91 km²

a) Both functions 3x + 7 and x are of the same order, which is the first order or linear order. (a) is the correct option.

In order to determine if two functions are of the same order, we compare their growth rates as the input approaches infinity. If the ratio of the two functions approaches a constant value, then they are of the same order.

a) For the functions 3x + 7 and x, as x approaches infinity, the ratio (3x + 7) / x approaches 3. Therefore, they are of the same order, which is the first order or linear order.

b) The functions 2x^2 + x - 7 and x^2 are of the same order, which is the second order or quadratic order.

c) The functions x + 1/2 and x are of the same order, which is the first order or linear order.

d) The functions log(x^2 + 1) and log2 x are of the same order, which is the logarithmic order.

e) The functions log10 x and log2 x are of the same order, which is the logarithmic order.

In each case, we determine the limit of the ratio of the two functions as the input approaches infinity. If the limit is a constant value, then the functions are of the same order. The order represents the growth rate or complexity of the functions as the input size increases.

Frequency of B grades = 10

So the probability of a student earning a grade of B is:

P(B) = Frequency of B grades / Total number of students

P(B) = 10 / 35

P(B) = 0.29 (rounded to the nearest hundredth)

The ordered pairs which are solutions to the system of inequalities given is (10, 2).

Given system of inequalities,

x + 2y ≥ 10

3x - 4y > 12

We have to find the solutions for the system of equations.

Let the equations be,

x + 2y = 10 [equation 1]

3x - 4y = 12 [equation 2]

From [equation 1],

x = 10 - 2y

Substituting in  [equation 2],

3(10 - 2y) - 4y = 12

30 - 6y - 4y = 12

-10y = -18

y = 9/5 = 1.8

x = 10 - 2y = 6.4

The system of equations hold true for (6.4, 1.8).

For (16, 9),

16 + (2 × 9) = 34 ≥ 10 is true.

(3 × 16) - (4 × 9) = 12 not greater than 12.

So this is not true.

For (10, 2),

10 + (2 × 2) = 14 ≥ 10 is true.

(3 × 10) - (4 × 2) = 22 > 12 is true.

Hence the correct ordered pair is (10, 2).

The production possibilities frontier (PPF) for a country is typically concave to the origin, meaning it is bowed outwards. This occurs because productive resources, such as land, labor, and physical capital, are not equally efficient in producing different goods or services.

The concave shape of the production possibilities frontier (PPF) reflects the concept of diminishing returns or increasing opportunity costs. As a country allocates more resources to the production of one good, it must sacrifice the production of other goods. However, as more resources are diverted towards a specific good, the additional output gained becomes smaller and smaller.
This occurs because not all productive resources are equally efficient in producing all goods or services. Some resources may be better suited for specific industries or have specialized skills. As a result, the PPF is bowed outwards, indicating that the opportunity cost of producing more of one good increases as the production of the other good is reduced.
In summary, the concave shape of the production possibilities frontier is a result of the varying efficiency and specialization of productive resources in different industries. This leads to increasing opportunity costs and the bowed-out nature of the PPF.

The velocity of the object in the last 50 seconds is 0 m/s, indicating that the object is at rest during that time interval.

To determine the velocity of the object in the last 50 seconds, we need to analyze the given displacement-time graph. Velocity can be calculated by finding the slope of the displacement-time graph during the specific time interval.

Looking at the graph, we see that the displacement starts at 30 meters (positive direction), decreases to 10 meters, and finally reaches 0 meters. The time interval for this change is 100 seconds (from 0 to 100 seconds). To find the velocity in the last 50 seconds, we focus on the interval from 50 to 100 seconds. During this period, the displacement remains constant at 0 meters.

Since velocity is the rate of change of displacement with respect to time, and the displacement is not changing (0 meters), the velocity during the last 50 seconds is 0 m/s. This means that the object is not moving or its velocity is constant at 0 m/s during that time interval.

In summary, based on the given displacement-time graph, the velocity of the object in the last 50 seconds is 0 m/s, indicating that the object is at rest or not moving during that specific time interval.

The diameter of the ball is approximately 16.67 meters.

To find the diameter of the ball, we can use the relationship between the distance traveled and the number of revolutions.

The circumference of a circle is given by the formula C = πd, where C is the circumference and d is the diameter.

Given that the ball rolls a distance of 3.5 meters and makes 15.0 revolutions, we can calculate the circumference of the path it travels:

C = 3.5 m * 15.0 = 52.5 m

Since each revolution covers the circumference of the ball, we have C = πd. Plugging in the known value for C, we can solve for the diameter (d):

52.5 m = πd

Dividing both sides of the equation by π, we get:

d = 52.5 m / π
