This week, a very large running race (5K) occured in Denver. The times were normally distributed, with a mean of 22.04 minutes and a standard deviation of 4.25 minutes.
a. What percent of runners took 36.915 minutes or less to complete the race?
b. What time in minutes is the cutoff for the fastest 59.87 %?
c. What percent of runners took more than 20.9775 minutes to complete the race?
a. To find the percentage of runners who took 36.915 minutes or less to complete the race, we can use the cumulative probability function of the normal distribution.
b. The cutoff time for the fastest 59.87% of runners can be determined by finding the corresponding value in the inverse normal distribution.
c. To calculate the percentage of runners who took more than 20.9775 minutes to complete the race, we need to subtract the cumulative probability from 100%.
a. To find the percentage of runners who took 36.915 minutes or less to complete the race, we can calculate the cumulative probability using the normal distribution. We can standardize the time value by subtracting the mean and dividing by the standard deviation. Then, we can look up the cumulative probability associated with this standardized value using a standard normal table or a statistical calculator.
b. The cutoff time for the fastest 59.87% of runners can be determined using the inverse normal distribution. We need to find the value in the distribution that corresponds to a cumulative probability of 59.87%. This can be done by using an inverse normal table or a statistical calculator.
c. To calculate the percentage of runners who took more than 20.9775 minutes to complete the race, we need to subtract the cumulative probability of 20.9775 minutes from 1 (or 100%). The cumulative probability represents the percentage of runners who completed the race within a certain time, so subtracting it from 100% gives us the percentage of runners who took more than that time.

the product of 8/9 and the sum of a number and -4 is less than or equal to 64 what are all the possible values of the number ? SHOW WORK!!!!!
Answer:
\(x\leq 76\)
Step-by-step explanation:
Let x = unknown number
⇒ \(\frac{8}{9}*(x-4)\leq 64\)
⇒ \(\frac{8(x-4)}{9} \leq 64\)
Multiply both sides by 9:
⇒ \(8(x-4)\leq 576\)
Expand brackets:
⇒ \(8x-32\leq 576\)
Add 32 to both sides:
⇒ \(8x\leq 608\)
Divide both sides by 8:
⇒ \(x\leq 76\)
At which x value(s) the following functions are not defined. Also write the domain in set notations 3x-2 = 2x+8 b) g(x) = x2
For the equation 3x-2 = 2x+8, we can solve for x to find where the function is not defined:
3x-2 = 2x+8
x = 10
Therefore, the function is not defined at x=10.
The domain of this function in set notation is: {x | x ≠ 10}
For the function g(x) = x^2, there are no x values for which the function is not defined. This is because we can square any real number and get a real number output.
The domain of this function in set notation is: {x | x ∈ ℝ} (meaning x can be any real number)
For the given functions:
a) 3x - 2 = 2x + 8
Since this is a linear equation, it is defined for all x values. Therefore, there are no x values for which the function is not defined. The domain in set notation is:
Domain = (-∞, +∞) or {x | x ∈ ℝ}
b) g(x) = x^2

Ash and her 2 friends went to dinner. If the bill was $124.72, and they left an 18% tip, how much did each person pay
Each person will pay $49.056. The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.
Which percentage is it?A percentage, often known as percent, is a division by 100. Percentage, which meaning "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.
Amount of bill = $124.72
and tip they left = 18% of $124.72
total amount is =$124.72 + $124.72*18%=$147.1696
so, each person pay= $147.1696/3=$49.056

Data is collected from a sample of 100 randomly selected students at the City University of New York that showed that the mean number of college credits earned per year is 25.6 with a standard deviation of 2.1
. Are these numbers statistics or parameters? Explain. The numbers are parameters because the numbers were calculated for a sample of City University of New York students and are estimates. The numbers are statistics because the numbers were calculated for a sample of City University of New York students and are estimates. The numbers are statistics because the numbers were calculated for all City University of New York students. The numbers are parameters because they numbers were calculated for all City University of New York students.
The correct answer is the numbers are statistics because the numbers were calculated from a sample of city University of New York students and are estimates.
The study of statistics focuses on gathering, organising, analysing, interpreting, and presenting data. It is customary to initiate with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.
Populations which can refer to a variety of groupings of individuals or things, such as "every individual living in a nation" or "each atom making up a crystal."
Every facet of data which includes the planning of data collecting in terms of the layout of surveys and experiments, is covered by statistics.
When census data cannot be gathered, statisticians devise specialised experiment designs and survey samples to get data. A representative sample ensures that generalisations and inferences from the sample to the entire population are reasonable.

Calculate the present value of these payments assuming an interest rate of 8% pa effective.
A sequence of payments is made annually in advance over a period of ten years, such that the payments made in the first year are of amount M100, payments made in the second year are of amount M200, payments made in the third year are of amount M300, and so on until the tenth year in which each payment is of amount M1,000.
The present value of these payments can be calculated as follows:
Let P be the present value of the payments made over 10 years. Then, according to the compound interest formula, the present value of each payment made in the first year can be given by:
PV of M100
\(= M100/(1 + 0.08)¹\)
\(= M92.59\)
Similarly, the present value of each payment made in the second year can be given by:
PV of M200
\(= M200/(1 + 0.08)²\)
\(= M165.29\)
Similarly, the present value of each payment made in the third year can be given by:
PV of M300

the bases of a trapezoid have lengths 5050 and 7575. its diagonals have lengths 3535 and 120120. find the area of the trapezoid.
The area of the trapezoid is approximately 2234.375 square units.
To find the area of a trapezoid, we can use the formula:
\(Area = (sum of the bases) * (height) / 2\)
Given that the lengths of the bases are 50 and 75, we can substitute these values into the formula:
\(Area = (50 + 75) * (height) / 2\)
Next, let's find the height of the trapezoid using the diagonals. The diagonals of a trapezoid divide it into four triangles. We can use the Pythagorean theorem to find the height of one of these triangles.
In one of the triangles, the base is 50, the diagonal is 35, and the height is unknown. We can use the Pythagorean theorem:
\(50^2 = 35^2 + height^2\)
Simplifying the equation:
\(2500 = 1225 + height^2\)
Subtracting 1225 from both sides:
\(height^2 = 1275\)
Taking the square root of both sides:
\(height ≈ √1275 ≈ 35.71\)
Now that we have the height, we can substitute it back into the formula:
\(Area = (50 + 75) * 35.71 / 2\)
Calculating:
\(Area ≈ 125 * 35.71 / 2Area ≈ 2234.375\)
Therefore, the area of the trapezoid is approximately 2234.375 square units.

Simple state space 2 Points Suppose that we have a small state space as follows: The node with the initial state has 4 successors/children, and each of those have 3 successors/children. That is the entire state space. Assume that the solution state is the last one explored.
What will the maximum length of the frontier be during a Depth-First Search?
During the Depth-First Search, the maximum number of nodes stored in the frontier at any provided point will be 4.
In a Depth-First Search (DFS), the maximum length of the frontier refers to the maximum number of nodes stored in the search frontier (also known as the stack) at any provided point during the search process.
In the provided state space, the node with the initial state has 4 successors, and each of those successors has 3 successors.
Since this is the entire state space, we can determine the maximum length of the frontier during a DFS by considering the longest path from the initial state to the solution state.
In this case, the longest path can be found by always choosing the last successor at each level until reaching the solution state.
Therefore, the maximum length of the frontier during a DFS in this state space will be equal to the depth of the longest path.
Based on the provided information, the longest path consists of 4 levels (initial state -> 4 successors -> 3 successors -> 3 successors -> solution state).
Therefore, the maximum length of the frontier during a DFS in this state space is 4.

A hockey puck sliding along frictionless ice with speed v to the right collides with a horizontal spring and compresses it by 3. 0 cm before coming to a momentary stop.
The maximum compression of the spring will depend on the spring's elasticity, or its ability to return to its original length after being stretched or compressed which is 2cm
If the same puck hits the spring at a speed of 2v, the spring will compress twice as much as it did when the puck was traveling at v. Thus, the spring's maximum compression will be 2 cm or twice its original compression of 1 cm.
It is important to note that the spring's elasticity will affect the maximum compression. If the spring is relatively stiff and has a low elasticity, it will not compress as far as a spring with a higher elasticity.

if a ladder of length 30 ft that is leaning against a wall has its upper end sliding down the wall at a rate of 1/2 ft / sec, what is the rate of change of the acute angle made by the ladder with the ground when the upper end is 18 ft above the ground?
The rate of change of the acute angle made by the ladder with the ground is -.021
According to the question,
Given: length of ladder(L)=30ft
Sliding down the wall at the rate of \($=\frac{d y}{d t}=\frac{-1}{2} \mathrm{ft} / \mathrm{sec}$$\)
To find: Rate of change of the acute angle made by the ladder when upper end is 18 ft above the ground.
Acute angle measure less than 90 degrees. right angle measures 90 degrees. obtuse angle measures more than 90 degrees
Now, we know that
\($$\sin \theta=\frac{y}{30}$$\)
let the time be (t) at general height (h) and at angle(θ)
\($$\begin{aligned}& \Rightarrow \quad \frac{d y}{d t}=-\frac{1}{2} \mathrm{ft} / \mathrm{sec} \\& \Rightarrow \quad \sin \theta=\frac{y}{30}\end{aligned}$$\)
Differentiate above equation
\($$\begin{aligned}\Rightarrow & (\cos \theta)\left(\frac{d \theta}{d t}\right)=\left(\frac{1}{30}\right)\left(\frac{d y}{d t}\right) \\& \text { Substitute } \frac{d y}{d t}=-\frac{1}{2} \mathrm{ft} / \mathrm{sec} . \\\Rightarrow & \frac{d \theta}{d t}=\left(\frac{1}{30}\right)\left(-\frac{1}{2}\right)\left(\frac{1}{\cos \theta}\right)\end{aligned}$$\)
\($$\Rightarrow \frac{d \theta}{d t}=\left(\frac{-1}{60}\right)\left(\frac{1}{\cos \theta}\right)$$\\\)
So, when h=18, from (1)
\($$\begin{aligned}& \Rightarrow \quad \sin \theta=\frac{18}{30} \\& \Rightarrow \sin \theta=\frac{3}{5}\end{aligned}$$\)
As we know that,
\($$\begin{aligned}& \sin ^2 \theta+\cos ^2 \theta=1 \\& =\cos \theta=\sqrt{1-\sin ^2 \theta} \\& =\cos \theta=\sqrt{1-\left(\frac{3}{5}\right)^2} \\& \Rightarrow \cos \theta=\frac{\sqrt{25-9}}{5} \\& \Rightarrow \cos \theta=\frac{4}{5}\end{aligned}$$\)
let the time be (t) at general height (h) and at angle(θ)
2) Substitute \($\left(\cos \theta=\frac{4}{5}\right)$\) from (4) eqn in.
(3) equ,
Then, \($\quad \frac{d \theta}{d t}=\left(-\frac{1}{60}\right)\left(\frac{5}{4}\right) \mathrm{rad} / \mathrm{sec}$\)
\($\frac{d \theta}{d t}=\frac{-1}{48} \mathrm{rad} / \mathrm{sec}$\)
Therefore, the rate of change of the acute angle made by the ladder with the ground is \($\frac{d \theta}{d t}=\frac{-1}{48} \mathrm{rad} / \mathrm{sec}$\).

As of the 2010 census, there were about 811,147 constituents per state senate district in Texas. What is the only state that had more constituents per senator
The mean is 172, the variance is 34.4, and the standard deviation is 5.86.
The United States has a system of bicameralism, which means that each state has two chambers in its legislature: a lower chamber (such as the Assembly or House of Representatives) and an upper chamber (such as the Senate).
The number of constituents per district in each chamber varies from state to state, and it is usually determined by the state's constitution or by a state redistricting commission.
As of the 2010 census, Texas had about 811,147 constituents per state senate district.
However, this is not the highest number of constituents per senator among all the states.
In fact, the state with the highest number of constituents per senator is California.
According to the U.S. Census Bureau, as of the 2010 census, California had a population of approximately 37.3 million people.
The state's constitution provides for 40 state senators, which means that each senator represents approximately 933,000 constituents.
This is significantly higher than the number of constituents per senator in Texas.
The high number of constituents per senator in California can be attributed to the state's large population and the fact that the number of state senators has not kept up with population growth.
The last time the number of state senators in California was increased was in 1973, when the state's population was around 20 million people.
In conclusion, while Texas has a high number of constituents per state senate district, it is not the only state with a high number of constituents per senator.
California has a significantly higher number of constituents per senator, due to its large population and the fact that the number of state senators has not kept up with population growth.

Each day(6 hours), 4284 passangers ride the bus.
To find passangers per hour, we must divide the total passangers by the total hours.
This is 4284(total passangers) divided by 6(total hours):
4284/6
=
714
So each hour, there are 714 passangers.
Hope this helps!
