Answer:

64 6/7

Step-by-step explanation:

The probability that a seat will be available for every person who shows up holding a reservation is approximately 0.0141 or 1.41% (rounded to four decimal places).

To use the normal approximation to the binomial distribution, we first need to check if the conditions for the approximation are met.

The conditions are:
1. The sample size is large enough (np ≥ 10 and nq ≥ 10)
2. The probability of success (getting a seat) is constant for each trial (person)
3. The trials are independent of each other

Assuming these conditions are met, we can use the normal distribution to approximate the binomial distribution.

Let p = probability of getting a seat = 0.95 (since each person holding a reservation has a 95% chance of getting a seat)
Let n = number of people with reservations who show up = 100 (this is not explicitly given, but we need to assume a value to solve the problem)

Calculate the mean (µ) and standard deviation (σ) of the binomial distribution using the formulas:
  µ = n * p
  σ = sqrt(n * p * (1-p))

The mean of the binomial distribution is μ = np = 100 * 0.95 = 95
The standard deviation of the binomial distribution is σ = sqrt(npq) = sqrt(100 * 0.95 * 0.05) = 2.179

Using the normal approximation, we can find the probability that all 100 people get a seat:
Calculate the z-score using the formula:
  z = (x - µ) / σ

P(X = 100) ≈ P(X > 99.5)
where X is the number of people who get a seat

We use X > 99.5 instead of X = 100 because the normal distribution is continuous while the binomial distribution is discrete.

Using the standard normal distribution table or calculator, we find that the probability of Z > 2.179 (where Z is the standard normal random variable) is 0.0141.

Therefore, the probability that a seat will be available for every person who shows up holding a reservation is approximately 0.0141 or 1.41% (rounded to four decimal places).

Answer:

Step-by-step explanation:

Ravi started with the improper fraction 25/4.

What is an improper fraction?

An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). For example, 7/4 is an improper fraction because the numerator 7 is greater than the denominator 4.

To solve this problem, we need to work backwards from the mixed number 6 1/4 to the improper fraction that Ravi started with.

The whole number part of the mixed number, 6, represents six groups of the denominator. The fractional part, 1/4, represents one quarter of the denominator. So the mixed number 6 1/4 can be represented as:

6 + 1/4 = 6 x 4/4 + 1/4 = 24/4 + 1/4 = 25/4

Hence, Ravi started with the improper fraction 25/4.

The statement a base class cannot contain a pointer to one of its derived classes is false because a base class can indeed contain a pointer to one of its derived classes.

In object-oriented programming, a base class can have a pointer to one of its derived classes. This is known as upcasting or polymorphism. Upcasting allows for the flexibility of treating derived class objects as instances of the base class.

By using pointers, a base class can refer to derived class objects and access their member functions and variables. This enables the base class to work with different derived classes without needing to know their specific types.

Pointers to derived classes can be stored in base class member variables or passed as function parameters. This allows for dynamic binding and the ability to invoke overridden functions based on the actual derived class type at runtime.

This concept is fundamental to achieving polymorphism and code reusability in object-oriented programming languages like C++ and Java. It facilitates the implementation of inheritance hierarchies and the ability to work with objects of different derived classes through a common base class interface.

Using binomial probability, the probability of having exactly 4 dice on 4, 5 or 6 is 5/32.

Using binomial probability, we can calculate the probability that out of the 5 dice thrown, the probability of having exactly 4 dice on 4, 5 or 6 can be calculated as;

\(P(X=k) = C(n, k) * p^k * (1-p)^(^n^-^k^)\)

In the given data;

n = 5

k = 4

p = 3/6 = 1/2

Using the binomial probability formula, we can calculate:

P(X=4) = C(5, 4) * (1/2)⁴ * (1 - 1/2)⁵⁻⁴

P(X=4) = 5 * (1/2)⁴ * (1/2)¹

P(X=4) = 5 * (1/16) * (1/2)

P(X=4) = 5/32

The correct answer is option b, which is 20 out of 70 throws.

SOLUTION:

A six-sided loaded die is a die that has a non-uniform probability distribution of the faces.

the probability of a number from 1-5 is the same,

by using probability to solve this problem.

The total probability of getting any number from 1-5 is equal to 5 times the probability of getting 6,

the probability of getting 6 is twice the probability of getting any number from 1-5.

the probability of getting any number from 1-5 is (1/7)

the probability of getting 6 is (2/7).

Now, let's calculate the expected number of 6's when the die is thrown 70 times:

Expected value = Number of throws * Probability of getting a 6

Expected value = 70 * (2/7)

Expected value = 20

So, the expected number of times the die would show the number 6 in 70 throws is 20.

Therefore, the answer is option b, which is 20 out of 70 throws.

Answer:

She is correct.

Step-by-step explanation:

She is correct.

Triangles QPS and QRS are congruent by SSS since all sides of one triangle are congruent to corresponding sides of the other triangle. Two pairs of sides are marked as congruent, and the third side, QS, is congruent to itself.

Then by CPCTC, angles P and R are congruent.

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Answer:

It will take 9 years for the population to double

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

\(P=P_o(1+r)^t\)

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.

Substituting in the equation:

\(2P_o=P_o(1+0.08)^t\)

Simplifying:

\(2=(1.08)^t\)

Taking logarithms:

\(\log 2=\log (1.08)^t\)

Applying the exponent property of logs:

\(\log 2=t\log (1.08)\)

Solving for t:

\(\displaystyle t=\frac{\log 2}{\log (1.08)}\)

Calculating:

\(t\approx 9\)

a. The length of the box = (40 - 2·x) cm

The height of the box = x cm

The width of the box = (25 - 2·x) cm

b. The formula for the volume of the box as a function of x is 4·x³ - 130·x² + 1000·x

c. The value of x that would maximize the volume of the box is x = 5 cm

d. The largest volume of the box is 2250 cm³

Step-by-step explanation:

a. The given parameters are;

The length of the cardboard = 40 cm

The width of the cardboard = 25 cm

The length of the box = (40 - 2·x) cm

The height of the box = x cm

The width of the box = (25 - 2·x) cm

b. The formula for the volume of the box = The area of the base of the box × Height of the box

The area of the base of the box =  (40 - 2·x) × (25 - 2·x) = 1000 - 80·x - 50·x + 4·x²

∴ The area of the base of the box = 4·x² - 130·x + 1000

The height of the box = x

The volume of the box = (4·x² - 130·x + 1000) × x = 4·x³ - 130·x² + 1000·x

The volume of the box in terms of x, V = 4·x³ - 130·x² + 1000·x

c. At the extremum point, dV/dx = 12·x² - 260·x + 1000 = 0

x = (260 ± √((-260)² - 4 × 12 × 1000))/(2 × 12)

x = (260 ± 140)/(24)

x = 5 or x = 16.\(\bar 6\)

At x = 5, the volume of the box is V = 4×5³ - 130×5² + 1000×5 = 2250

The volume of the box is V = 2250 cm³

At x = 16.67, the volume is 4×16.67³ - 130×16.67² + 1000×16.67 = -925.\(\overline {925}\)cm³

Therefore, the value of x that would maximize the volume of the box is x = 5 cm

d. The largest volume of the box is 4×(5 cm)³ - 130×(5 cm)² + 1000×(5 cm) = 2250 cm³.

Answer:

Horizontal: y = 9

Vertical: x = 3

Step-by-step explanation:

Any point is given in the form (x,y). The first number is the x and the second number is the y.

Horizontal lines (a left-right line like the horizon) have an equation in the form "y = anumber" This works because a horizontal line has ZERO slope. So there is no x in the equation because--

y = 0x + b

y = b (a number, use the y-number from the point)

A vertical line has undefined slope so you can't even pretend to use a slope equation. A vertical line (up and down) has an equation in the form

"x = anumber" Use the x from the point.

Horizontal line through (3,9) is y=9.

Vertical line through (3,9) is x=3

Answer: False

Step-by-step explanation:

Researchers typically report the adjusted R-squared value in addition to the regular R-squared value, not because they lack confidence in the actual R-squared, but because the adjusted R-squared provides additional information about the goodness of fit of a statistical model. The regular R-squared value measures the proportion of the variance in the dependent variable that is explained by the independent variables in the model. However, it can be biased and increase as more predictors are added to the model, even if the additional predictors do not contribute significantly to the prediction.

The adjusted R-squared, on the other hand, takes into account the number of predictors in the model and penalizes the addition of irrelevant predictors. It provides a more conservative measure of the goodness of fit by adjusting for the number of predictors and the sample size. Researchers often use the adjusted R-squared to evaluate and compare different models with varying numbers of predictors or to assess the overall explanatory power of a model while considering its complexity.

In summary, researchers report the adjusted R-squared value to address the limitations of the regular R-squared and to provide a more accurate assessment of the model's goodness of fit.
