Answer:

19.5

Step-by-step explanation:

2 x 19.5 = 39 - 29 = 10 :D

The probability of at least one appearance in a 21-alternate period is 0.969803

(a) The appearance  rate is 10 passengers nanosecond , so the anticipated number of advents  in nanosecond is also 10. The probability of no advents  in one minute is given by the Poisson distribution with parameter lambda = 10:

P(X = 0) = \(e^{(-lambda)}\) \(lambda^{0}\) / 0! =  \(e^{(-10)}\)* \(10^{0}\) / 1! = 0.000045 (rounded to 6 decimal places)

Therefore, the probability of no arrivals in one-minute period is 0.000045.

(b) To compute the probability that three or fewer passengers arrive in one-minute period, we can use the cumulative distribution function (CDF) of the Poisson distribution:

P(X <= 3) = sum from i=0 to 3 of P(X = i)

= P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

= \(e^{-10}\) *\(10^{0}\) / 0! + \(e^{(-10)}\) * \(10^{1}\)/ 1! + \(e^{(-10)}\) * \(10^{2}\) / 2! + \(e^{(-10) }\)* \(10^{3}\)/ 3!

= 0.010336 (rounded to 6 decimal places)

Therefore, the probability that three or fewer passengers arrive in one-minute period is 0.010336.

(c) The arrival rate is 10 passengers per minute, which is equivalent to 10/60 = 1/6 passengers per second. Therefore, the expected number of arrivals in a 21-second period is (1/6) * 21 = 3.5 passengers. The probability of no arrivals in a 21-second period is given by the Poisson distribution with parameter lambda = 3.5:

P(X = 0) = \(e^{(-lambda)}\) * l\(lambda^{0}\) / 0! = \(e^{(-3.5)}\) * \(3.5^{0}\)/ 1! = 0.030197 (rounded to 6 decimal places)

Therefore, the probability of no arrivals in a 21-second period is 0.030197.

(d) The probability of at least one arrival in a 21-second period is equal to 1 minus the probability of no arrivals:

P(at least one arrival) = 1 - P(no arrivals)

= 1 - 0.030197

= 0.969803 (rounded to 6 decimal places)

Answer:

y = | x | + 1

Step-by-step explanation:

Given y then y + c represents a vertical translation of y

•  If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 1 unit up, thus

y = | x | + 1

Answer:

The integers could be 21 and 22

or -22 and -21

Step-by-step explanation:

If two integers are consecutive, then it means that their difference is just 1

if we have the initial value as x , then the other value could be x-1 or x + 1

let us go with x-1

So the product here is;

x(x-1) = 462

x^2-x = 462

x^2 -x -462 = 0

x^2 -22x + 21x - 462 = 0

x(x-22) + 21(x-22) = 0

(x + 21)(x-22) = 0

x = -21 or x = 22

If x = -21

x -1 = -21-1 = -22

if x = 22

x -1 = 22-1 = 21

Answer:

Step-by-step explanation:

length of Legs of the right angle triangle = 22 (unit) and 26 (unit)

To find the length of hypotenuse of the right angle triangle, we have to use Pythagoras property

Lets keep hypotenuse as "h" and one leg as  "a" and another as "b"

\(a^{2}\) + \(b^{2}\) = \(h^{2}\)

\(22^{2}\) + \(26^{2}\) = \(h^{2}\)

484 + 676 = \(h^{2}\)

\(h^{2}\) = 1,160

h = \(\sqrt{1,160}\)

h = 34.05 (unit)

Answer: D.9100

Step-by-step explanation:

Answer:

The correct answer is $9,100

Step-by-step explanation:

The expression (¬p ∨ q) ∧ (p → ¬r ∧ ¬p) ∧ (p ∨ r) is satisfiable.

The given logical expression is (¬p ∨ q) ∧ (p → ¬r ∧ ¬p) ∧ (p ∨ r). To determine whether it is satisfiable, we can create a truth table to evaluate the expression for all possible combinations of truth values for the variables p, q, and r.

The truth table for the given expression would have 2^3 = 8 rows since there are three variables. We can evaluate the expression for each row by substituting the corresponding truth values for p, q, and r and applying the logical operators.

After evaluating the expression for all eight rows, if there is at least one row where the expression evaluates to true, then the expression is satisfiable. On the other hand, if the expression evaluates to false for all rows, then it is unsatisfiable.

Since the truth table evaluation can be quite extensive to write out in a single response, I'll provide the summary of the answer:

The expression (¬p ∨ q) ∧ (p → ¬r ∧ ¬p) ∧ (p ∨ r) is satisfiable.

Answer:

Charles need \(3\frac{1}{5}\) more ounces of seeds.

Step-by-step explanation:

Given that:

Quantity of seeds Charles has = \(2\frac{2}{3}\) = \(\frac{8}{3}\) ounces

Quantity of seeds Charles need = \(4\frac{4}{5} = \frac{24}{5}\) ounces

Let,

x be the number of remaining seeds Charles need.

x = Seeds needed - Seeds Charles already have

x = \(\frac{24}{5}-\frac{8}{3}\)

x = \(\frac{72-24}{15}\)

x = \(\frac{48}{15}\)

x = \(\frac{16}{5}\)

x = \(3\frac{1}{5}\) ounces

Hence,

Charles need \(3\frac{1}{5}\) more ounces of seeds.

Dont do it. Just take the detention

Jenna drove 80 miles when it was not raining, and 60 miles when it was raining, for a total of 140 miles during her road trip.

During Jenna's road trip of 140 miles, she drove at two different speeds due to weather conditions. When it was not raining, she drove at a speed of 50 miles per hour, which means she covered a distance of 50 x (140 - 1.5) = 6850 feet in that time.

When it was raining, she drove at a speed of 40 miles per hour for a duration of 1.5 hours. Using the formula Distance = Speed x Time, we can calculate the distance Jenna drove while it was raining:

Distance = 40 x 1.5 = 60 miles

Therefore, Jenna drove a total of 60 miles when it was raining during her road trip. To calculate the distance she drove when it wasn't raining, we can subtract the distance she drove while it was raining from the total distance of her road trip:

Total distance - Distance driven in the rain = 140 - 60 = 80 miles.

So Jenna drove 80 miles when it was not raining, and 60 miles when it was raining, for a total of 140 miles during her road trip.

The correct relationship of the three principles is: The well-ordering principle for the integers is equivalent to strong mathematical induction, and neither is equivalent to weak mathematical induction.

The well-ordering principle for the integers states that every non-empty set of non-negative integers has a least element. Strong mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for all cases up to a certain value, and then proving that it must also be true for the next case.

This requires assuming the truth of all cases up to a certain value, which is where the well-ordering principle comes in. Weak mathematical induction is a proof technique that involves proving that a statement is true for a base case, and then assuming that it is true for a particular case, and then proving that it must also be true for the next case.

Weak mathematical induction does not require assuming the truth of all cases up to a certain value, and is therefore weaker than strong mathematical induction.
