The probability to wait more than 15 seconds to connect is 50% and the probability to wait at least 10 more seconds after waiting 10 seconds is 33.33%.

x = old modem establish connection = [0, 30]

Probability density function or PDF is

f(x) = \(\frac{1}{b-a}\); 0 ≤ x ≤ 30

Probability to wait more than 15 seconds to connect is

f(X>5) = \(\int\limits^{30}_{15} {f(x)} \, dx\)

= \(\int\limits^{30}_{15} {\frac{1}{b-a}} \, dx\)

= \(\frac{1}{30-0} \, [x]^{30}_{15}\)

= \(\frac{30-15}{30}\)

= 0.5 or 50%

Probability if already waited 10 seconds and having to wait at least 10 more seconds is equal to wait at least 20 seconds from start. So,

f(X>5) = \(\int\limits^{30}_{20} {f(x)} \, dx\)

= \(\int\limits^{30}_{20} {\frac{1}{b-a}} \, dx\)

= \(\frac{1}{30-0} \, [x]^{30}_{20}\)

= \(\frac{30-20}{30}\)

= 0.3333 or 33.33%

Thus, the 50% probability to wait more than 15 seconds to connect and 33.33% probability to wait at least 20 seconds to connect.

Problem 1

Answer: Choice A) The domain in interval notation is [2, 6]

Explanation:

The domain is the set of allowed x inputs. For graphs, we look at the left-most point and right-most point. This tells us the boundaries of the domain. We go from x = 2 to x = 6, including both endpoints.

We can write the domain as this inequality \(2 \le \text{x} \le 6\) which condenses to the interval notation [2, 6]

Make sure to use square brackets to include each endpoint.

Choice B is a trick answer since we won't be using roster notation. Roster notation is only useful for discrete domains, but this relation has a continuous domain.

==============================================

Problem 2

Answer: Choice B) The range in interval notation is [-4, 0]

Explanation:

The range is the set of y values in a relation. Look at the lowest and highest points to determine the boundaries.

The lowest point occurs when y = -4, and the highest is when y = 0. The range is anything between these endpoints, including the endpoints themselves.

Therefore we get \(-4 \le \text{y} \le 0\) which condenses to [-4, 0]

This time choice A is a trick answer because the range is continuous rather than discrete.

The radius of convergence for this series is also infinity.

The McLaurin series for the special function erf(z) is given by:
erf(z) = \((2/√π) * ∑ ((-1)^n * z^(2n+1)) / (n! * (2n+1))\)

The radius of convergence for the series is infinity, which means it converges for all complex numbers.

The special function Si(z) does not have a McLaurin series representation. However, it can be expressed as a Taylor series around z=0. The series is given by:
Si(z) = z - (1/3!) *\(z^3 + (1/5!) * z^5 - (1/7!) * z^7 + .\)..

The required volume of the given solid is (√16 - r²) -(-√16 - r²).

The measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units.

Volume and the notion of length are connected.

Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface.

The cubic meter (m3), a derived unit, is the SI unit of volume.

So, the integrand often takes the form z upper z lower, where z stands for the solid's lower and upper borders.

We are treating the sphere as a hemisphere as of right now, with the XY-plane serving as its lower boundary. Consequently, you must multiply by 2.

The solid's volume is (√16 - r²) -(-√16 - r²).

A rectangular washcloth is 8 inches long. The area of the washcloth is 56 square inches. The width of the rectangular washcloth is 7 inches.  

To find the width of the washcloth, we can use the formula for the area of a rectangle, which is given by the product of its length and width. In this case, we are given the length of the washcloth as 8 inches and the area as 56 square inches. Let's assume the width of the washcloth as 'w' inches.

According to the given information, the area of the washcloth is 56 square inches. So, we can set up the equation: length × width = area.

Substituting the given values, we have 8 inches × w inches = 56 square inches. Solving for 'w', we divide both sides of the equation by 8 inches, which gives us w = 56 square inches ÷ 8 inches = 7 inches.

Therefore, the width of the rectangular washcloth is 7 inches.

(a) The mean of Z in case (a) is -60 and the variance is 400.

(b) The mean of Z in case (b) is 280 and the variance is 3600.

(c) The mean of Z in case (c) is 60 and the variance is 65.

(d) The mean of Z in case (d) is -20 and the variance is 65.

(e) The mean of Z in case (e) is 80 and the variance is 505.

To find the mean and variance of the random variable Z for each case, we can use the properties of means and variances.

(a) Z = 40 - 5X

Mean of Z:

E(Z) = E(40 - 5X) = 40 - 5E(X) = 40 - 5 * 20 = 40 - 100 = -60

Variance of Z:

Var(Z) = Var(40 - 5X) = Var(-5X) = (-5)² * Var(X) = 25 * Var(X) = 25 * (4)² = 25 * 16 = 400

Therefore, the mean of Z in case (a) is -60 and the variance is 400.

(b) Z = 15X - 20

Mean of Z:

E(Z) = E(15X - 20) = 15E(X) - 20 = 15 * 20 - 20 = 300 - 20 = 280

Variance of Z:

Var(Z) = Var(15X - 20) = Var(15X) = (15)² * Var(X) = 225 * Var(X) = 225 * (4)² = 225 * 16 = 3600

Therefore, the mean of Z in case (b) is 280 and the variance is 3600.

(c) Z = X + Y

Mean of Z:

E(Z) = E(X + Y) = E(X) + E(Y) = 20 + 40 = 60

Variance of Z:

Var(Z) = Var(X + Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (c) is 60 and the variance is 65.

(d) Z = X - Y

Mean of Z:

E(Z) = E(X - Y) = E(X) - E(Y) = 20 - 40 = -20

Variance of Z:

Var(Z) = Var(X - Y) = Var(X) + Var(Y) = (4)² + (7)² = 16 + 49 = 65

Therefore, the mean of Z in case (d) is -20 and the variance is 65.

(e) Z = -2X + 3Y

Mean of Z:

E(Z) = E(-2X + 3Y) = -2E(X) + 3E(Y) = -2 * 20 + 3 * 40 = -40 + 120 = 80

Variance of Z:

Var(Z) = Var(-2X + 3Y) = (-2)² * Var(X) + (3)² * Var(Y) = 4 * 16 + 9 * 49 = 64 + 441 = 505

Therefore, the mean of Z in case (e) is 80 and the variance is 505.

Step-by-step explanation:

The number 3.23×10^6, expressed in standard decimal notation, is 3,230,000. In scientific notation, a number is expressed as the product of a coefficient and a power of 10.

In this case, the coefficient is 3.23, and the power of 10 is 6. To convert this number into standard decimal notation, we need to multiply the coefficient by the corresponding power of 10. The power of 10, in this case, is 10^6, which means 10 raised to the power of 6. This is equivalent to 1 followed by six zeros: 1,000,000. To obtain the standard decimal notation, we multiply the coefficient, 3.23, by 1,000,000.

Calculating the multiplication, we have:

3.23 × 1,000,000 = 3,230,000.

Hence, the number 3.23×10^6, expressed in standard decimal notation, is 3,230,000. This means that the number is equal to 3.23 million.

Answer:

The height of the pyramid is 11.8 cm to the nearest tenth of a cm

Step-by-step explanation:

The formula of the volume of a pyramid is V = \(\frac{1}{3}\) × A × h, where

∵ A right rectangular pyramid has base dimensions of 23.2 cm, 17.0 cm

∵ The area of the rectangle = Length × width

→ Assume that the length is 23.2 and the width is 17.0

∴ A = 23.2 × 17.0

∴ A = 394.4 cm²

∵ Its volume is 1552.4 cm³

∴ V = 1552.4 cm³

→ Substitute A and V in the rule above

∵ 1552.4 = \(\frac{1}{3}\) × 394.4 × h

∴ 1552.4 = \(\frac{1972}{15}\) h

→ Divide both sides by \(\frac{1972}{15}\)

∴ 11.80831643 = h

→ Round it to the nearest tenth of a cm

∴ h = 11.8 cm

∴ The height of the pyramid is 11.8 cm to the nearest tenth of a cm

the television station can show 10 45-second commercials per hour.

To convert hours into minutes, you simply multiply the number of hours by 60, since there are 60 minutes in an hour.

So, if you want to convert 3 hours into minutes, you would do:

3 hours x 60 minutes/hour = 180 minutes

Therefore, 3 hours is equivalent to 180 minutes.

There are 60 minutes in an hour, and 7 1/2 minutes is equal to 7.5 minutes.

So, the television station shows commercials for 7.5 minutes per hour.

We can convert 45 seconds to minutes by dividing it by 60:

45 seconds ÷ 60 = 0.75 minutes

To find out how many 45-second commercials the television station can show per hour, we can divide the total number of minutes of commercials by the length of each commercial:

7.5 minutes ÷ 0.75 minutes/commercial = 10 commercials

Therefore, the television station can show 10 45-second commercials per hour.

The person's average speed during her commute is 33.75 mph.

The speed of an object can be obtained by comparing the distance covered to the traveling time needed.

speed = distance / time

Take a look at the problem. As the information given is time in minutes and speed in miles per hour (mph), then we have to convert the time into an hour unit.

Total time = 20 minutes = 20/60 hour = 1/3 hour

Break time = 5 minutes

Commuting time = 20 - 5 = 15 minutes

                                         = 15/60 hour = 1/4 hour

Given the speed = 45 mph, then the distance covered during commuting time is:

Distance = speed x time

              = 45 x 1/4

              = 11.25 miles

Then we can calculate the average time, by comparing the distance covered to the total time:

Average speed = distance / total time

                          = 11.25 / 1/3

                          = 33.75 mph

Thus the average speed during the commute is 33.75 mph.

Given statement solution :- The star would cross the observer's meridian (the imaginary line running from the North celestial pole through the observer's zenith to the South celestial pole) exactly halfway between rising and setting. As the Earth rotates, this would take roughly 12 hours to complete.

The number of hours a star is above the horizon depends on several factors, including the star's declination (angular distance north or south of the celestial equator), the observer's latitude, and the time of year. However, assuming you are referring to an equatorial star (one with a declination of 0 degrees) and you are at the equator (latitude 0 degrees), such that the star rises directly in the East and sets directly in the West, it would be above the horizon for approximately 12 hours out of a 24-hour day.

This is because, in this scenario, the star would cross the observer's meridian (the imaginary line running from the North celestial pole through the observer's zenith to the South celestial pole) exactly halfway between rising and setting.

The function f : Z x Z → Z x Z defined by \(f(m,n) = (5m+4n, 4m+3n)\) is bijective, with its inverse given by \(f^{-1}(m,n) = (-3m + 4n, 4m - 5n)\). This means that for every pair of integers (m,n), the function f maps them uniquely to another pair of integers, and the inverse function \(f^{-1}\) maps the resulting pair back to the original pair.

The inverse of the function f(m,n) = (5m+4n, 4m+3n) is \(f^{-1}(m,n) = (-3m + 4n, 4m - 5n)\).

To show that the function f is bijective, we need to prove both injectivity (one-to-one) and surjectivity (onto).

Injectivity:

Assume f(m1, n1) = f(m2, n2), where (m1, n1) and (m2, n2) are distinct elements of Z x Z.

Then, (5m1 + 4n1, 4m1 + 3n1) = (5m2 + 4n2, 4m2 + 3n2).

This implies 5m1 + 4n1 = 5m2 + 4n2 and 4m1 + 3n1 = 4m2 + 3n2.

By solving these equations, we find m1 = m2 and n1 = n2, proving injectivity.

Surjectivity:

Let (a, b) be any element of Z x Z. We need to find (m, n) such that f(m, n) = (a, b).

By solving the equations 5m + 4n = a and 4m + 3n = b, we find m = -3a + 4b and n = 4a - 5b.

Thus, f(-3a + 4b, 4a - 5b) = (5(-3a + 4b) + 4(4a - 5b), 4(-3a + 4b) + 3(4a - 5b)) = (a, b), proving surjectivity.

Since the function f is both injective and surjective, it is bijective. The inverse function \(f^{-1}(m, n) = (-3m + 4n, 4m - 5n)\) is obtained by interchanging the roles of m and n in the original function f.
