The number of Avis buses travelling to and from the airport as per given time is equal to 6 buses per hour.
Average traveling time for a round trip is 24 minutes
To determine how many Avis buses are traveling to and from the airport.
Number of round trips a single bus can make in an hour.
A single bus can make,
24 minutes = 1 round trip
⇒ 1 minutes = ( 1/24 ) round trip
⇒ 60 minutes = 60/24
⇒ 1 hour = 2.5 round trips
Number of buses Avis needs to dispatch in order to maintain a bus arrival frequency of every 4 minutes.
Avis needs to dispatch,
4 minutes = 1 bus
⇒ 1 minute = ( 1/4) bus
⇒ 60 minutes = ( 60/ 4) buses
= 15 buses per hour.
Total number of buses needed
= number of buses per hour / (number of round trips a single bus can make in an hour)
= 15 buses per hour / 2.5 round trips per bus per hour
= 6 buses.
Therefore, Avis needs 6 buses to maintain a bus arrival frequency of every 4 minutes for its shuttle service between the LAX airport and its offices.

Round your answers to two decimal places. Whenf = 10 % , V = i mv. Whenf = 50 % , V = mv. When f = 90 %, V = i mv.
The value of l, k, and c are 1, 284.2 and 4.0000 respectively. When f = 10%, V = -0.0032 mV, When f = 50%, V = 0.0092 mV, When f = 90%, V = -0.0193 mV.
(a) The formula given for f(V) is the logistic function, which is of the form f(V) = L / (1 + C*e^(-kV)). Therefore, we can compare this to the given formula to obtain:
L = 1
k = 1421/5 = 284.2
C = 4
Rounding C to four decimal places, we get C = 4.0000.
(b) To find the voltages at which 10%, 50%, and 90% of the channels are open, we can use the logistic function formula and solve for V when f = 0.1, 0.5, and 0.9 respectively.
For f = 0.1:
0.1 = 1 / (1 + 4*e^(-284.2V))
0.9 + 4*e^(-284.2V) = 10
e^(-284.2V) = 1.525
-284.2V = ln(1.525)
V = -0.0032 mV
For f = 0.5:
0.5 = 1 / (1 + 4*e^(-284.2V))
1 + 4*e^(-284.2V) = 2
e^(-284.2V) = 0.25
-284.2V = ln(0.25)
V = 0.0092 mV
For f = 0.9:
0.9 = 1 / (1 + 4*e^(-284.2V))
4*e^(-284.2V) = 9
e^(-284.2V) = 2.25
-284.2V = ln(2.25)
V = -0.0193 mV
Rounding these answers to two decimal places, we get:
When f = 10%, V = -0.0032 mV.
When f = 50%, V = 0.0092 mV.
When f = 90%, V = -0.0193 mV.

16^x = 32
We can use the fact that 32 is equal to 2 raised to the power of 5:
32 = 2^5
Substituting this into the equation gives:
16^x = 2^5
We can then rewrite 16 as 2^4, since 16 is equal to 2 raised to the power of 4:
(2^4)^x = 2^5
Simplifying the left side of the equation gives:
2^(4x) = 2^5
Now we can see that the bases of both sides of the equation are equal, so we can set the exponents equal to each other:
4x = 5
Dividing both sides by 4 gives:
x = 5/4
Therefore, the solution to the equation 16^x = 32 is x = 5/4.

The probability of Tabria randomly selecting a peanut butter cookie and then an oatmeal cookie is 8/35 or 8 in 35 chance
The probability of selecting a peanut butter cookie first is 8/29, since there are 8 peanut butter cookies and 29 total cookies of all variety in the bag. Then, the probability of selecting an oatmeal cookie after eating a peanut butter cookie is 8/28, since there are now only 28 cookies remaining in the bag and 8 of them are oatmeal cookies. To find the combined probability, we multiply the individual probabilities:
8/29 × 8/28 = 8/35.

7. The size of a television screen is determined by its diagonal measure. If the height of
a screen is 32 inches and the width is 57 inches, what size is the TV considered to be
in inches? Round to the nearest whole number.
Using Pythagoras theorem, the size of the TV will be 65 inches.
What is Pythagorean Theorem?
The Pythagorean Theorem is a fundamental concept in mathematics that describes the relationship between the sides of a right triangle. It states that in any right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse).
In equation form, the Pythagorean Theorem can be written as:
a² + b² = c²
where a and b are the lengths of the two legs and c is the hypotenuse.
Now,
We can use the Pythagorean theorem to find the diagonal measure of the television screen.
In this case, the height and width of the screen form the legs of a right triangle, so we can use the following equation:
(diagonal)² = (height)² + (width)²
Substituting the given values, we get:
(diagonal)² = (32)² + (57)²
(diagonal)² = 1024 + 3249
(diagonal)² = 4273
Taking the square root of both sides
diagonal = √(4273) ≈ 65.37
Therefore, the size of the TV screen, as measured diagonally, is approximately 65 inches (rounded to the nearest whole number).

What is the equation, in slope-intercept form, of the line parallel to -5x + y = 2 that passes through the point
with coordinates (-2, 1)?
Answer:
y = 5x + 11
Step-by-step explanation:
- first rearrange -5x + y = 2 and you'll have y = 5x + 2
- the slopes of parallel lines are equal so the slope of the line is 5
so far we have y = 5x + b
- to get b, replace the values in the equation by the values of the given point
(1) = 5(-2) + b
- rearrange and calculate, b = 11

The height of water left in the can is determined as 9.9 cm.
option B.
What is the height of water left in the can?The height of water left in the can is calculated by the difference between the volume of a cylinder and volume of a cone.
The volume of the cylindrical can is calculated as;
V = πr²h
where;
r is the radiush is the heightV = π(4.6 cm)²(13.5 cm)
V = 897.43 cm³

Josh lit a 14-inch candle. She noticed that it was getting an inch shorter every 30 minutes. Let x be the number of hours and y be the total height of the candle
The height of the candle after x hours is given by the equation y = 2x + 14.
Let's first convert the time interval to hours. There are 60 minutes in an hour, so 30 minutes is equivalent to 0.5 hours.
After x hours, the candle will have burned down by 2x inches (since it burns 1 inch every 0.5 hours).
If y is the total height of the candle, then we can write the equation:
y - 2x = 14
We can solve for y:
y = 2x + 14
So the height of the candle after x hours is given by the equation y = 2x + 14.

Assume that arrival times at a drive-through window follow a Poisson process with mean rite lambda = 0.2 arrivals per minute. Let T be the waiting time until the third arrival. Find the mean and variance of T. Find P(T lessthanorequalto 25) to four decimal places. The mean of T is minutes, the variance of T is minutes, the variance of P(T < 25) =
The variance of P(T ≤ 25) is equal to 0.6431 * (1 - 0.6431), which is approximately 0.2317 (rounded to four decimal places).
In a Poisson process with arrival rate λ, the waiting time until the k-th arrival follows a gamma distribution with parameters k and 1/λ.
In this case, we want to find the waiting time until the third arrival, which follows a gamma distribution with parameters k = 3 and λ = 0.2. The mean and variance of a gamma distribution with parameters k and λ are given by:
Mean = k / λ
Variance = k / λ^2
Substituting the values, we have:
Mean = 3 / 0.2 = 15 minutes
Variance = 3 / (0.2^2) = 75 minutes^2
So, the mean of T is 15 minutes and the variance of T is 75 minutes^2.
To find P(T ≤ 25), we need to calculate the cumulative distribution function (CDF) of the gamma distribution with parameters k = 3 and λ = 0.2, evaluated at t = 25.
P(T ≤ 25) = CDF(25; k = 3, λ = 0.2)
Using a gamma distribution calculator or software, we can find that P(T ≤ 25) is approximately 0.6431 (rounded to four decimal places).
Therefore, the variance of P(T ≤ 25) is equal to 0.6431 * (1 - 0.6431), which is approximately 0.2317 (rounded to four decimal places).

let f ( x ) = 6.8 sin ( x ) 5.3 cos ( x ) . what is the maximum and minimum value of this function?
The value of f(x) = 6.8 sin(x) 5.3 cos(x) maximum value is 31.52 and the minimum value is -31.52.
We may utilise the knowledge that the sum of two sine and cosine functions with the same period is always constrained by the values of their respective amplitudes to determine the maximum and lowest values of the function
f(x) = 6.8 sin(x) 5.3 cos(x).
More specifically, the product's maximum value happens when both functions have the same sign and its biggest absolute value, while its lowest value happens when both functions have the opposite sign and its smallest absolute value.
Sin(x) has an amplitude of 1, while cos(x) has an amplitude of 1.
Hence, the greatest value of f(x) occurs at x = π/4 or x = 5π/4 (and at every multiple of 2π from there) when sin(x) and cos(x) have the same sign and their absolute values are both 1.
F(x) can have a maximum value of:
f(π/4) = 6.8 sin(π/4) 5.3 cos(π/4)
f(π/4) = 6.8(1/√2)(5.3/√2)
f(π/4) = 31.52
Similar to this, the smallest value of f(x) occurs at x = 3π/4 or x = 7π/4 (and at every multiple of 2π from there) when sin(x) and cos(x) have opposing signs and their absolute values are both 1. Hence, f(x) has the following minimal value:
f(3π/4) = 6.8 sin(3π/4) 5.3 cos(3π/4) = -6.8(1/√2)(5.3/√2) = -31.52

This is an example of a correlation between the two variables. When two variables are correlated, they tend to change together in a predictable way. In other words, when one variable goes up, the other tends to go up as well, or when one variable goes down, the other tends to go down as well.
