Question: The amount of time to complete a physical activity in a PE class is approximately normally normally distributed with a mean of 35.4 seconds and a ...

Answers

Answer 1

a) The probability that a randomly chosen student completes the activity in less than 29.9 seconds is approximately 0.1292.

b) The probability that a randomly chosen student completes the activity in more than 40 seconds is approximately 0.3085.

c) The proportion of students who take between 29.4 and 39.1 seconds to complete the activity is approximately 0.3839.

d) 95% of all students finish the activity in less than approximately 49.816 seconds.

a) To calculate the probability of completing the activity in less than 29.9 seconds, we need to find the z-score using the formula z = (x - μ) / σ, where x is the given time, μ is the mean, and σ is the standard deviation. By looking up the z-score in the standard normal distribution table, we find the corresponding probability.

b) Similar to part (a), we calculate the z-score for completing the activity in more than 40 seconds and find the corresponding probability from the standard normal distribution table.

c) To determine the proportion of students taking between 29.4 and 39.1 seconds, we calculate the z-scores for both values and find the corresponding probabilities. Then, we subtract the smaller probability from the larger probability.

d) To find the time at which 95% of students finish the activity, we use the z-score corresponding to the 95th percentile (1.645) and calculate the time using the formula x = μ + z * σ.

Understanding the probabilities and proportions in relation to the normal distribution helps in analyzing the performance and characteristics of students in physical activities.

let |g| 5 15. if g has only one subgroup of order 3 and only one of order 5, prove that g is cyclic. generalize to |g| 5 pq, where p and q are prime.

Answers

To prove that the group g is cyclic, we analyze the possible values of the order |g|. We consider the cases for each possible value and demonstrate that in all cases, g is either cyclic or leads to a contradiction.

For |g| = 1, 2, 3, 5, or 7, the groups of these orders are always cyclic.

If |g| = 4, 6, 8, 9, 10, 12, or 15, we show that g cannot have the required subgroups. Assuming g is not cyclic, we find an element x of order 2 and additional elements y, z, w, etc., also of order 2. This contradicts the given conditions since g would be isomorphic to Z₂ × Z₂ or have more than one subgroup of order 3 or 5.

For composite orders |g| = pq, where p and q are prime, we generalize the analysis. By Cauchy's theorem, g has elements of order p and q, and since there is only one subgroup of each order, they are cyclic. We show that the intersection of these subgroups cannot have an order of pq, leading to a contradiction. Hence, g is cyclic.

Therefore, in all cases, g is proved to be cyclic. QED.

adam, benin, chiang, deshawn, esther, and fiona have internet accounts. some, but not all, of them are internet friends with each other, and none of them has an internet friend outside this group. each of them has the same number of internet friends. in how many different ways can this happen?

Answers

(a) Therefore, the range of possible values for "x" is 1 to 5. (b) Summing up these values, we get 5 + 10 + 10 + 5 + 1 = 31.  Therefore, there are 31 different ways this can happen

To find the number of different ways this can happen, we can consider the number of internet friends each person can have. Since each person has the same number of internet friends, let's denote that number as "x". We can then create equations based on the given information:

1. Some, but not all, of them are internet friends with each other: This means that at least two people are internet friends with each other, but not everyone is friends with each other. This implies that the minimum number of internet friends any person can have is 1, and the maximum number is 5 (since there are 6 people in total).

Therefore, the range of possible values for "x" is 1 to 5.

2. None of them has an internet friend outside this group: This means that each person's internet friends must be within this group of 6 people. So, the number of internet friends each person can have is limited to the remaining 5 people.

To find the number of different ways this can happen, we need to sum up the possible values of "x" and calculate the corresponding combinations. For "x = 1", we choose 1 person out of 5 remaining people, giving us C(5, 1) = 5. For "x = 2", we choose 2 people out of 5 remaining people, giving us C(5, 2) = 10.

Similarly, for "x = 3", "x = 4", and "x = 5", we have C(5, 3) = 10, C(5, 4) = 5, and C(5, 5) = 1 respectively. Summing up these values, we get 5 + 10 + 10 + 5 + 1 = 31.

The height of the elm tree is \(\mathbf{37\frac{1}3}\) feet

The given parameters are:

\(\mathbf{Apple = 10\frac 23\ ft}\)

An elm tree is 3 1/2 times as an apple tree.

So, we have:

\(\mathbf{Elm = 3\frac 12 \times Apple}\)

This gives

\(\mathbf{Elm = 3\frac 12 \times 10\frac 23\ ft}\)

Express as improper fractions

\(\mathbf{Elm = \frac 72 \times \frac{32}3\ ft}\)

a simple random sample of 40 items resulted in a sample mean of 25. the population standard deviation is 5. what is the standard error of the mean? (round your answer to two decimal places).

Answers

The standard error of the mean is approximately 0.79 (rounded to two decimal places).

Define standard error ?

The standard error is a statistical term that measures the variability of a sample mean or an estimate of a population parameter from its true value. It is the standard deviation of the sampling distribution of the mean. In simpler terms, the standard error measures how much the sample mean varies from the true population mean. A smaller standard error indicates that the sample mean is more likely to be representative of the population mean, while a larger standard error suggests that the sample mean may not be as reliable.

The formula for the standard error of the mean is:

\(SE = \frac{\sigma }{\sqrt{n}}\)

Where σ is the population standard deviation and n is the sample size.

Substituting the given values:

\(SE =\frac{5}{\sqrt{40}}\)

SE ≈ 0.79

Therefore, the standard error of the mean is approximately 0.79 (rounded to two decimal places).

i offer you a gamble in which you win $1200 if a card randomly drawn from a standard 52-card deck is red and you lose $1200 if the card is black. what is the expected value of the gamble?

Answers

The expected value of a gamble can be calculated by multiplying the probability of winning by the amount you could win and subtracting the probability of losing multiplied by the amount you could lose.

In this case, we are given that if a red card is drawn from a standard 52-card deck, you win $1200, and if a black card is drawn, you lose $1200.

First, let's determine the probability of drawing a red card from a standard 52-card deck. In a standard deck, there are 26 red cards (13 hearts and 13 diamonds) and 26 black cards (13 spades and 13 clubs). So the probability of drawing a red card is 26/52, which simplifies to 1/2 or 0.5.

Next, let's calculate the probability of losing, which is the probability of drawing a black card. Similarly, the probability of drawing a black card is also 26/52 or 1/2.

Now, we can calculate the expected value using the formula:
Expected value = (probability of winning * amount won) - (probability of losing * amount lost)

Expected value = (0.5 * $1200) - (0.5 * $1200)
Expected value = $600 - $600
Expected value = $0

Therefore, the expected value of the gamble is $0. This means that, on average, you neither win nor lose money in the long run by playing this gamble.

A man of mass 60kg runs with a constant velocity. He has kinetic energy of 750j. Calculate his velocity

Answers

Answer:

the velocity of the man is 5 m/s.

Step-by-step explanation:

The kinetic energy of a moving object is given by the equation:

K.E. = 0.5 * m * v^2

where

K.E. is the kinetic energy

m is the mass of the object

v is the velocity of the object

In this problem, we are given that the man has a mass of 60 kg and a kinetic energy of 750 J.

So,

750 J = 0.5 * 60 kg * v^2

Solving for v:

v^2 = (2 * 750 J) / 60 kg

v^2 = 25 J/kg

v = sqrt(25 J/kg)

v = 5 m/s

Therefore, the velocity of the man is 5 m/s.

Answers

Based on the given data, the expected expense of a machine being used 25.3 hours per week is $34.22 hundred.

To calculate the expected expense of a machine being used 25.3 hours per week, we need to first find the regression line for the given data. We can use statistical software or a calculator to find the regression line, which is:

Annual Maintenance Expense = 7.99 + 0.79(Weekly Usage)

Using this regression line, we can plug in the mean weekly usage of 25.3 hours to find the expected expense:

Annual Maintenance Expense = 7.99 + 0.79(25.3) \(\approx\) 34.22 hundred dollars

Since the expected expense of a machine being used 25.3 hours per week is greater than the cost of the maintenance contract, which is $3,200 per year or $32 hundred dollars, it would be recommended to purchase the maintenance contract.

Which function is nonlinear? Y=4x+9 y=7/x-6 y=x-6/7 15 points

Answers

Answer:

The answer is y = 7/x -6.

Step-by-step explanation:

A linear function is one where x and y are both to the first power.  Using this knowledge, let's look at the options that we are given.

y = 4x + 9

In the above equation, both x and y are raised to the first power, so we know that this equation is linear.

y = 7/x - 6

In the above equation, y is raised to the first power, but x is not.  Since x is in the denominator of a fraction, it actually has a power of -1, which makes this equation nonlinear.

y = x - 6/7

In the above equation, both x and y are raised to the first power, making the equation linear.

Therefore, the correct choice is y =7/x - 6.

Seeds cost for a farmer are 40$ per acre for corn and 30$ per acre for soybeans . How many acres of each crop should the farmer plant if she wants to spend no more than 2400 on seed? Express your answer as a liner inequality with appropriate nonnegative restrictions and draw its graph

Answers

Given that:

- The seeds cost is 40$ per acre for corn.

- The seeds cost is 30$ per acre for soybeans.

- The farmer wants to spend no more than $2400.

• Let be "x" the number of acres of seeds for corn and "y" the number of acres of seeds for soybeans.

You know that the total amount of money has to be less than or equal to $2400. Therefore, you can write the following Linear Inequality to represent that situation:

\(40x+30y\leq2400\)

You can rewrite it in another form by solving for "y":

\(\begin{gathered} 30y\leq-40x+2400 \\ \\ y\leq\frac{-40x}{30}+\frac{2400}{30} \end{gathered}\)\(y\leq-\frac{4}{3}x+80\)

Since the number of acres cannot be negative:

\(\begin{gathered} x\ge0 \\ y\ge0 \end{gathered}\)

• You can identify that the boundary line is:

\(y=-\frac{4}{3}x+80\)

It is written in Slope-Intercept Form:

\(y=mx+b\)

Where "m" is the slope and "b" is the y-intercept.

In this case, you can identify that the y-intercept is:

\(b=80\)

In order to find the x-intercept, substitute this value of "y" into the equation and solve for "x" (because the y-value is zero when the line intersects the x-axis):

\(y=0\)

Then, you get:

\(0=-\frac{4}{3}x+80\)\(\frac{(-80)(3)}{-4}=x\)\(x=60\)

You can identify that the symbol of the inequality is:

\(\leq\)

It indicates that the line must be solid and the shaded region must be below the boundary line.

Knowing all this information, you can graph the inequality on the Coordinate Plane (Remember that the values of the variables must be greater than or equal to zero. Then, you must shade with a different color the region in which "x" and "y" are greater than or equal to zero).

Hence, the answer is:

- Linear Inequality:

\(40x+30y\leq2400\)

- Nonnegative restrictions:

\(\begin{gathered} x\ge0 \\ y\ge0 \end{gathered}\)

Case 6: sin θ = 1 / 2, cos θ = √3 / 2, tan θ = √3 / 3, sec θ = 2√3 / 3, csc θ = 2

How to find the exact values of trigonometric functions

In this problem we find four cases of trigonometric functions, whose exact values of remaining trigonometric functions must be found. The trigonometric functions are defined below:

sin θ = y / √(x² + y²)

cos θ = x / √(x² + y²)

tan θ = y / x

cot θ = x / y

sec θ = √(x² + y²) / x

csc θ = √(x² + y²) / y

Now we proceed to determine the exact values of the trigonometric functions:

Case 3: y = 4, √(x² + y²) = 5

x = √(5² - 4²)

x = 3

cos θ = 3 / 5

tan θ = 4 / 3

cot θ = 3 / 4

sec θ = 5 / 3

csc θ = 5 / 4

Case 4: x = 5, √(x² + y²) = 6

y = √(6² - 5²)

y = √11

sin θ = √11 / 6

tan θ = √11 / 5

cot θ = 5√11 / 5

sec θ = 6 / 5

csc θ = 6√11 / 11

Case 5: x = 8, √(x² + y²) = √73

y = √(73 - 8²)

y = 3

cos θ = 8√73 / 73

sin θ = 3√73 / 73

tan θ = 3 / 8

cot θ = 8 / 3

csc θ = √73 / 3

Case 6: x = √3, y = 1

sin θ = 1 / 2

cos θ = √3 / 2

tan θ = √3 / 3

sec θ = 2√3 / 3

csc θ = 2

(Note: The answer is not 3 wire and 2 wire control.) A passenger on a cruise ship was injured by a rope thrown while the ship was docking. The passenger was sitting on a lounge chair on the third deck when she was struck by the weighted end of a rope thrown by an employee of Port Everglades, where the boat was docking. These ropes, or heaving lines, were being thrown from the dock to the second deck, and the passenger was injured by a line that was thrown too high. The trial court granted the cruise lines motion for directed verdict on the ground there was no evidence that the cruise line knew or should have known of the danger. The cruise line contended that it had no notice that this "freak accident" could occur. What is the duty of a cruise ship line to its passengers? Is there liability here? Does it matter that an employee of the port city, not the cruise lines, caused the injury? Should the passenger be able to recover?
