The probability of a person being randomly choosing having waiting time greater than 4.25 is 0.2917 or 29.17%.

To answer this question we need to know about-

Probability is the measure of the likelihood of an event to happen. The probability value ranges between 0 and 1.

When the probability value is 0, it means that the event is impossible to happen.

When the probability value is 1, it means that the event is certain to happen.

Uniform distribution is when the values of a probability distribution are spread uniformly across the interval, it is called a Uniform distribution

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 minutes.

The probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is found as follows:

Let X = Waiting time of a randomly selected passenger P(X > 4.25) = ?

Now we have to use the uniform distribution formula to find the probability:

P(C< X >D)=C-D/B-A

where C = lower value of the selected interval

           D= upper value of the selected interval

           B= highest value of the selected interval

           A= lowest value of the selected interval

putting above values in the formula -

P(X > 4.25) = 6 - 4.25/6-0= 0.2917

Hence the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is 0.2917.

The perimeter of the track is of 377 m.

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

Considering the rectangle with area 5500 m² and base 110 m, the height h, representing the diameter d of the circumference, is obtained as follows:

110d = 5500

d = 550/11

d = 50 m.

The radius is half the diameter, hence it is given as follows:

r = 25 m.

The perimeter is given as follows:

Hence it is given as follows:

P = 2 x 110 + 2 x 3.14 x 25

P = 377 m.

The probability of the horse finishing in second place is approximately 0.29.

To convert the odds given as "29 to 71" into a probability value, we can divide the number of favorable outcomes (29) by the total number of possible outcomes (29 + 71 = 100).

The probability is calculated as:

Probability = Number of favorable outcomes / Total number of possible outcomes.

In this case, the probability is 29/100, which is equal to 0.29.

To convert odds to probability, we divide the number of favorable outcomes (29) by the total number of outcomes (29 + 71 = 100). The probability of the horse finishing in second place is 29/100, which simplifies to 0.29 or 29%.

This means there is a 29% chance or likelihood of the horse finishing in second place based on the given odds.

Answer:

y = 2 * 4^x

Step-by-step explanation:

We could define a wide variety of rules!

It turns out that any set of n (x, y) pairs can be modeled by a singular polynomial of degree (n-1) or less, and by infinitely many polynomials of degree n or more! And we're only talking polynomials!

Let's input it into a polynomial interpolation calculator:

\((27 x^4)/4 - (63 x^3)/2 + (225 x^2)/4 - (51 x)/2 + 2\)

Well I don't love this.

Let's try to actually look for patterns. We see that the function is rapidly increasing. More and more, actually. Let's look for the ratios of each next y

8/2 = 4

32/8 = 4

128/32 = 4

512/128 = 4

BINGO!

So we can define the rule as:

y = 2 * 4^x

Answer:

x = 200

Step-by-step explanation:

Plug in 15 as y into the equation and solve for x:

1/5x - 2/3y = 30

1/5x - 2/3(15) = 30

1/5x - 10 = 30

1/5x = 40

x = 200

So, when y = 15, x = 200

The appropriate critical value for constructing a confidence interval in this setting is 1.88.

To find the appropriate critical value for constructing a confidence interval at a 94% confidence level, we can use a standard normal distribution table or a calculator.

First, we need to find the value of alpha, which is the significance level, which is equal to 1 - the confidence level. In this case, alpha is equal to 1 - 0.94 = 0.06.

Next, we need to find the critical value z* from the standard normal distribution table or calculator, which corresponds to the area to the right of z* being equal to alpha/2 = 0.03.

Using a standard normal distribution table or calculator, we can find that the critical value z* is approximately 1.88.

The point that lies on the line passing through point Z and is perpendicular to line AB can be represented as (x-coordinate of point Z, corresponding y-coordinate).

To find the point on the line that passes through point Z and is perpendicular to line AB, we can use the concept of the perpendicular bisector.

Step 1: Find the midpoint of line AB. To do this, add the x-coordinates of A and B and divide by 2 to get the x-coordinate of the midpoint. Repeat the same process for the y-coordinates to get the y-coordinate of the midpoint.

Step 2: Calculate the slope of line AB. To do this, subtract the y-coordinate of point A from the y-coordinate of point B, and divide by the difference in x-coordinates. This will give you the slope of line AB.

Step 3: Calculate the negative reciprocal of the slope of line AB. This will give you the slope of the line that is perpendicular to line AB.

Step 4: Use the slope-intercept form of a line, y = mx + b, where m is the slope from step 3 and (x, y) is the midpoint from step 1, to find the equation of the line perpendicular to AB.

Step 5: Substitute the x-coordinate of point Z into the equation from step 4 to find the corresponding y-coordinate.

The point that lies on the line passing through point Z and is perpendicular to line AB can be represented as (x-coordinate of point Z, corresponding y-coordinate).

The force required to keep a hockey puck sliding at a constant velocity, neglecting ice friction and air resistance, is equal to its weight. The correct option is "equal to its weight."

When a hockey puck is set in motion across a frozen pond and there is no ice friction or air resistance, the only force acting on the puck is its weight, which is the force due to gravity pulling it downward. According to Newton's first law of motion (the law of inertia), an object at a constant velocity will continue to move at that velocity unless acted upon by an external force.

Since the puck is already in motion and we want to maintain its constant velocity, the force required to counteract its weight and keep it sliding is equal to its weight. This is because the weight of an object is the force exerted on it by gravity, and in the absence of other forces, an equal and opposite force is needed to maintain the object's motion without acceleration.

1. Calculate the difference between the x-coordinates: x2 - x1

2. Square the result of step 1: (x2 - x1)^2

3. Calculate the difference between the y-coordinates: y2 - y1

4. Square the result of step 3: (y2 - y1)^2

5. Add the results of step 2 and step 4: (x2 - x1)^2 + (y2 - y1)^2

6. Calculate the square root of the result of step 5: √((x2 - x1)^2 + (y2 - y1)^2)

This final result is the length of the line segment.

The formula for a line segment is relatively straightforward. Begin by calculating the difference between the x-coordinates (x2 - x1) and square the result. Then find the difference between the y-coordinates (y2 - y1) and square the result. Add the two results together and take the square root of the sum. This final result is the length of the line segment. This formula can be used to calculate the length of any line segment, regardless of its size or shape.

To achieve a 95% confidence level with a margin of error of 0.01, a minimum of 9604 donors must be examined. Using a prior estimate of 15% of college-age students having hypertension, to be 99% confident with a margin of error of 0.01, a minimum of 8461 donors must be examined.

To determine the minimum number of donors required to achieve a 95% confidence level with a margin of error of 0.01, we can use the following formula:

\(n = (Z^2 * p * (1-p)) / E^2\)

where:

n = sample size

Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to Z = 1.96)

p = estimated proportion of college students with hypertension (prior estimate of 0.15)

E = margin of error (0.01)

Plugging in the values into the formula:

\(n = (1.96^2 * 0.15 * (1 - 0.15)) / 0.01^2\)

n = (3.8416 * 0.15 * 0.85) / 0.0001

n = 0.4896 / 0.0001

n ≈ 4896

Therefore, to be 95% confident with a margin of error of 0.01, we would need to examine a minimum of 4896 donors.

Using the same formula, but aiming for a 99% confidence level with a margin of error of 0.01 and a prior estimate of 0.15, the calculation would be as follows:

\(n = (2.576^2 * 0.15 * (1 - 0.15)) / 0.01^2\)

n = (6.656576 * 0.15 * 0.85) / 0.0001

n = 0.852 / 0.0001

n ≈ 8520

Therefore, to be 99% confident with a margin of error of 0.01, we would need to examine a minimum of 8520 donors.
