# passengers for H hours  would be   2500H

    f (H) = 2500 H

Answer:

a) 2500H

b) 20,000

Step-by-step explanation:

To find the number of passengers carried, multiply the number of passengers carried in an hour by the total hours.

  a)    Passengers carried in an hour = 2500

     Passengers carried in 'H' hours = 2500 * H = 2500H

b)  H = 8 hours

  Passengers carried in 8 hours = 2500 * 8

The cumulative distribution function of t, the number of years to maturity for a randomly selected bond is a. 1/4, b. 3/4, c. 1/2, d. 1/3.

The probability of a randomly selected bond maturing exactly after 5 years is 1/4. The probability of a randomly selected bond maturing after more than 3 years is 3/4. The probability of a randomly selected bond maturing between 1.4 and 6 years is 1/2.

a) P(T=5) = F(5) - F(4) = 3/4 - 1/2 = 1/4

b) P(T>3) = 1 - P(T≤3) = 1 - F(3) = 1 - 1/4 = 3/4

c) P(1.4 < T < 6) = F(6) - F(1.4) = 3/4 - 1/4 = 1/2

d) P(T≤5 | T≥2) = P(2 ≤ T ≤ 5) / P(T≥2) = (F(5) - F(2)) / (1 - F(2)) = (3/4 - 1/4) / (1 - 1/4) = 1/3

The probability that the system can decode the correct message is approximately 0.9477.

The random variable N denotes the number of error-free transmissions for a single meter upon receiving the wake-up call.

Since each transmission is error-free with probability p=0.9 and the transmissions are independent, the number of error-free transmissions follows a binomial distribution with parameters n=4 (number of trials) and p=0.9 (probability of success in each trial).

The probability mass function (PMF) of N is given by:

P(N=k) = (4 choose k) × [tex]0.9^k[/tex] × [tex]0.1^{(4-k)}[/tex], for k = 0, 1, 2, 3, 4

where (4 choose k) is the binomial coefficient, which represents the number of ways to choose k successes out of 4 trials.

The error correction scheme can decode the correct message if at least 3 out of 4 transmissions are error-free. Let X be the number of error-free transmissions for a single meter.

Then the probability that the system can decode the correct message is:

P(X >= 3) = P(X = 3) + P(X = 4)

To find these probabilities, we use the PMF of N from part 1:

P(X = 3) = P(N = 3) + P(N = 4) = (4 choose 3) × [tex]0.9^3[/tex] × 0.1 + (4 choose 4) × [tex]0.9^4[/tex] × [tex]0.1^0[/tex] = 0.2916

P(X = 4) = P(N = 4) = (4 choose 4) × [tex]0.9^4[/tex] × [tex]0.1^0[/tex] = 0.6561

Therefore, the probability that the system can decode the correct message is:

P(X >= 3) = P(X = 3) + P(X = 4) = 0.2916 + 0.6561 = 0.9477.

So the probability that the system can decode the correct message is approximately 0.9477.

Answer:

The proportion of the width to the length of the original photograph is 4:6, which can be simplified to 2:3. To maintain the same proportion, the width of the reduced photograph must also be 2/3 of the length.

Since the length of the space in the brochure is 4 inches, the width of the space must be:

width = (2/3) x length

width = (2/3) x 4

width = 8/3

width ≈ 2.67 inches

Therefore, the width of the space in the brochure should be approximately 2.67 inches to maintain the proportion of the photograph.

In slope-intercept form, the equation of the line is y = (5/4)x + 6 1/2.

An equation in mathematics is a statement that two expressions are equal. An equation can be written in the form of a mathematical expression on the left side equal to a value or another mathematical expression on the right side. There are different types of equations, including linear equations, quadratic equations, and exponential equations, among others. Equations can be solved for a specific variable, and the solution is the value of the variable that makes the equation true. The process of solving an equation involves isolating the variable on one side of the equation and finding its value.

Here,

The slope-intercept form of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point at which the line intersects the y-axis. To find the equation of a line in slope-intercept form given its slope and a point on the line, we can use the following steps:

Use the point-slope form of a line: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Plug in the slope and the point: y - 6 = (5/4)(x + 4).

Solve for y: y = (5/4)x + (26/4).

Simplify the equation: y = (5/4)x + 6 1/2.

So, the equation of the line in slope-intercept form is y = (5/4)x + 6 1/2.

The probability of finding exactly 6 defects in a carpet roll  is 0.0435 and the probability of finding 2 or fewer defects in a carpet roll is 0.405.

a. To find the probability of finding exactly 6 defects in a carpet roll chosen at random, we can use the Poisson formula:

P(X = 6) = (e^-λ  * λ ^6) / 6!

putting λ = 2.0, we get:

P(X = 6) = (e^-2 * 2^6) / 6! = 0.0435

So the probability of  6 defects in a carpet roll chosen at random is 0.0435.

b. To find the probability of finding 2 or fewer defects in a carpet roll, we can use the cumulative distribution function of the Poisson distribution:

P(X <= 2) = 1 - P(X > 2)

Using the Poisson formula, we can calculate P(X > 2) as follows:

P(X > 2) = 1 - (P(X = 0) + P(X = 1) + P(X = 2))

Plugging in λ   = 2.0, we get:

P(X > 2) = 1 - (0.135 + 0.27 + 0.54) = 0.595

So P(X <= 2) = 1 - 0.595 = 0.405

So the probability of finding 2 or fewer defects in a carpet roll is 0.405.

The person is 36m away from the boat.

The given figure is triangular in nature. In order to determine the distance of the person from the boat, we will use the pythagoras theorem.

Given the following parameters

GH = 20m

GK = 30m

The measure of the length HK (The distance of the person from the boat,) is calculated as:

HK^2 = GH^2 + GK^2

HK^2 = 20^2+ 30^2

HK^2 = 400+900
HK^2 = 1300

HK = 36m

A cylinder is one of the most basic curvilinear geometric shapes and has traditionally been solid in three dimensions. In elementary geometry, it is regarded as a prism with a circle as its basis.

A three-dimensional geometric shape known as a cone has a flat base and a smooth, tapering vertex. A cone is made up of several line segments, half-lines, or lines that connect to a single point.

State: 99% CI for the true difference in proportions where p1 = the proportion of all U.S. men who can identify India on the map and p2 = the proportion of all US women who can identify India on the map. The main answer is (-0.216, 0.056).

The 95% confidence interval for the true difference in the proportion of U.S. men and women who can identify India on a map is (-0.206, 0.066). This means that we are 95% confident that the true difference in proportions lies between -0.206 and 0.066.

To construct this confidence interval, we use the formula:

CI = (p1 - p2) ± z*SE

where p1 and p2 are the sample proportions for men and women respectively, z is the critical value for a 95% confidence level (1.96), and SE is the standard error of the difference in proportions.

The sample proportion for men is 27/90 = 0.3, and for women it is 38/100 = 0.38. Therefore, p1 - p2 = -0.08. The standard error is:

SE = sqrt(p1*(1-p1)/n1 + p2*(1-p2)/n2) = sqrt(0.30.7/90 + 0.380.62/100) = 0.084

Substituting these values into the formula, we get:

CI = (-0.08) ± 1.96*0.084 = (-0.206, 0.066)

Thus, we can say with 95% confidence that the true difference in proportions of U.S. men and women who can identify India on a map lies between -0.206 and 0.066. This means that there may not be a significant difference between the two proportions.
