Answers

A variable is a characteristic or attribute that can take on different values. It is an observable and measurable property of an object or phenomenon, which can be used to describe and analyze it.

Parameters are used in inferential statistics to make conclusions about a population based on a sample of data.

(a) If you decide to select based on proportion of 10% from each group, the number of patients selected from each group would be: Group A = (10/100) x 100 = 10 patients Group B = (10/100) x 30 = 3 patients Group C = (10/100) x 30 = 3 patients.

(b) The classified groups can be named as follows: Group A = 10 years of education or less Group B = More than 10 years but less than or equal to 20 years of education Group C = More than 20 years of education.

(c) The sampling method employed in the selection process was stratified sampling. Stratified sampling is a type of probability sampling technique where the population is divided into homogeneous subgroups or strata, and the researcher selects a simple random sample from each subgroup or stratum.

The researcher chooses a proportion of participants from each subgroup to represent the population as a whole, which allows for more precise estimates of the population parameters than simple random sampling.

The sample is selected randomly from the stratified sample, which ensures that the sample is representative of the population.

A variable is a characteristic or attribute that can take on different values. It is an observable and measurable property of an object or phenomenon, which can be used to describe and analyze it.

Variables are used in research to test hypotheses, determine relationships between different phenomena, and make predictions about future outcomes.

Fizzy Waters promotes their alkaline water product for everyone on the basis that alkaline water is good for health as it neutralizes acids produced in the body. They boast having a mean alkalinity level of 50 mg/liter. Alkaline water has a higher pH level than regular drinking water and Fizzy Waters claims that its higher Hydrogen content provides better hydration than regular water. To test their claim, you contact Fizzy Waters and they allow you to collect samples from their manufacturing plant to test for yourself. You collect 100 random samples of their alkaline water and find that the mean and standard deviation are y = 32.2mg/liter and 14.4mg/liter. With 99% confidence, is there enough evidence to support their claim that the population mean exceeds 50 mg/liter?

Answers

Answer:

The mean of 50 mg/liter is not inside the 99% interval, so there is not enough evidence to support their claim.

Step-by-step explanation:

First we need to find the z-value for a confidence of 99%

The value of alpha for a 99% confidence is:

\(1-\alpha/2 = 0.99\)

\(\alpha/2 = 0.01\)

\(\alpha = 0.005\)

Looking in the z-table, we have z = 2.575.

Now we can find the standard error of the mean:

\(\sigma_{\bar{x} }= s_x/\sqrt{n}\)

\(\sigma_{\bar{x} }= 14.4/\sqrt{100}\)

\(\sigma_{\bar{x} }=1.44\)

Finding the 99% confidence interval, we have:

\(99\%\ interval = (\bar{x} - z\sigma_{\bar{x}}, \bar{x} + z\sigma_{\bar{x}})\)

\(99\%\ interval = (32.2 - 2.575*1.44, 32.2 + 2.575*1.44)\)

\(99\%\ interval = (28.492, 35.908)\)

The mean of 50 mg/liter is not inside the 99% interval, so there is not enough evidence to support their claim.

Hannah took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.90 plus $3.75 per mile. The total fare was $80.65, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.

Answers

Answer: y=3.75x+1.9

Step-by-step explanation: the pick up fee would be the y-intercept and the per mile cost would be the slope.

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Pick up fee charges = $1.90

Charges per mile = $3.75

Total fare = $80.65

The number of miles traveled = x

We can write an equation as:

1.90 + 3.75x = 80.65

The number of miles traveled:

1.90 + 3.75x = 80.65

Subtract 1.90 on both sides.

1.90 + 3.75x - 1.90 = 80.65 - 1.90

3.75x = 78.75

Divide both sides by 3.75.

x = 21.

Thus,

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

4. Amy, Betty and Carol have 96 books altogether. Betty has 6 books less than Amy and Carol has half as many as Betty. How many books does each girl have?​

Answers

The Amy has 42 books, Betty has 36 books, and Carol has 18 books.

Let's set up equations to represent the given information:

Let A represent the number of books Amy has.

Let B represent the number of books Betty has.

Let C represent the number of books Carol has.

Let's say Amy has x books.

Betty has 6 books less than Amy, so Betty has (x - 6) books.

Carol has half as many books as Betty, so Carol has (x - 6)/2 books.

According to the problem, the total number of books they have is 96.

So, we can write the equation:

x + (x - 6) + (x - 6)/2 = 96

To solve the equation, we can simplify it by multiplying through by 2 to remove the fraction:

2x + 2(x - 6) + (x - 6) = 192

2x + 2x - 12 + x - 6 = 192

5x - 18 = 192

5x = 210

x = 42

Amy has 42 books.

Betty has (42 - 6) = 36 books.

Carol has (36)/2 = 18 books.

-1000 2/3 is not real fraction. True or false

Answers

True, While "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.

The statement "-1000 2/3 is not a real fraction" is true. A real fraction is a mathematical expression that represents a ratio of two real numbers. In a fraction, the numerator and denominator are both real numbers, and they can be positive, negative, or zero.

In the given statement, "-1000 2/3" is not a valid representation of a fraction. The presence of a space between "-1000" and "2/3" suggests that they are separate entities rather than being part of a single fraction.

To represent a mixed number (a whole number combined with a fraction), a space or a plus sign is typically used between the whole number and the fraction. For example, a valid representation of a mixed number would be "-1000 2/3" or "-1000 + 2/3". However, without the proper formatting, "-1000 2/3" is not considered a real fraction.

It's important to note that "-1000 2/3" can still be expressed as an improper fraction. To convert it into an improper fraction, we multiply the whole number (-1000) by the denominator of the fraction (3) and add the numerator (2). The result would be (-1000 * 3 + 2) / 3 = (-3000 + 2) / 3 = -2998/3.

In conclusion, while "-1000 2/3" is not a real fraction, it can be represented as the improper fraction -2998/3.

Answer:

x₁ = 179 , x₂ = 17 , x₃ = - 3

Step-by-step explanation:

x₁ - 9x₂ + 7x₃ = 5 → (1)

      x₂ + 7x₃ = - 4 → (2)

              x₃ = - 3

substitute x₃ = - 3 into (2) and solve for x₂

x₂ + 7(- 3) = - 4

x₂ - 21 = - 4 ( add 21 to both sides )

x₂ = 17

substitute x₂ = 17 and x₃ = - 3 into (1) and solve for x₁

x₁ - 9(17) + 7(- 3) = 5

x₁ - 153 - 21 = 5

x₁ - 174 = 5 ( add 174 to both sides )

The domain of fis x ≤0, while the domain of g is x ≥ 0.

Answers

When the graph of f(x) = √x is reflected across the y-axis, the domain of g becomes x ≤ 0, while the domain of f remains x ≥ 0.

The correct statement is: The domain of f is x ≥ 0, while the domain of g is x ≤ 0.

The function f(x) = √x represents the square root function, which is defined for x values greater than or equal to 0 (x ≥ 0). This is because the square root of a negative number is not a real number.

When the graph of f(x) = √x is reflected across the y-axis, it creates the graph of function g. This reflection results in a reversal of the x-values. In other words, the positive x-values of f(x) become negative in g(x) and vice versa.

Since the domain of f is x ≥ 0, the reflection across the y-axis flips the domain, resulting in the domain of g being x ≤ 0. This means that the x-values of g are less than or equal to 0.

Answer: $144

This is because you have 6 children’s tickets each for $10, so you take the 6x10 which gives you $60. Then you have 6 adult tickets which cost $14, so you take 6x14 which equals $84. When added together that is $144!

You are thinking of opening a small copy shop. It costs $5000 to rent a copier for a year, and it costs $0.03 per copy to operate the copier. Other fixed costs of running the store will amount to $400 per month. You plan to charge an average of $0.10 per copy, and the store will be open 365 days per year. Each copier can make up to 100,000 copies per year.

For 1000 copies= 1000×365×0.10=$36500

For 1500 copies=1500×365×0.10=$54750

For 2000 copies=2000×365×0.10=$73000

Total cost using five copiers= 400×12+5000×5+500000×0.03= $44800

Total cost using four copiers=

400×12+5000×5+400000×0.03=

f) Q1 for the x¯distribution = 21 points a game.

g) P( ∑x > 829.0774) = 0.8888 = 88.88%.

Assumption of normality is not necessary, as the sample sizes are greater than 30.

Normal Probability Distribution

The z-score of a measure X of a variable that has mean \(\mu\) and standard deviation \(\sigma\) is given by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The z-score measures how many standard deviations the measure X is above or below the mean of the distribution, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).Also by the Central Limit Theorem, for the sum of n instances of a variable, the mean is of \(\n\mu\) and the standard deviation is of \(\sigma\sqrt{n}\).Finally, by the Central Limit Theorem, assumption of normality is only necessary when the sample size is less than 30.

For a single game, the mean and the standard deviation of the number of points scored are given as follows:

\(\mu = 22, \sigma = 9.3\)

For the average of 41 games, the standard error is:

\(s = \frac{9.3}{\sqrt{41}} = 1.45\)

Hence the distribution is: x¯ ~ N(22, 1.45).

For the sum of the 41 games, the mean and the standard error are given as follows:

41 x 22 = 902.\(s = 9.3\sqrt{41} = 59.55\).

Hence the distribution is: ∑x ~ N(902, 59.55).

In item c, the probability is one subtracted by the p-value of Z when X = 19.8214, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem:

\(Z = \frac{X - \mu}{s}\)

Z = (19.8214 - 22)/1.45

Z = -1.5

Z = -1.5 has a p-value of 0.0668.

1 - 0.0668 = 0.9332 = 93.32%.

The 60th percentile for the distribution is X when Z = 0.253, hence:

\(Z = \frac{X - \mu}{s}\)

0.253 = (X - 22)/1.45

X - 22 = 0.253 x 1.45

X = 22.37.

For item e, the probability is the p-value of Z when X = 23.2262 subtracted by the p-value of Z when X = 20.6214, hence:

X = 23.2262:

\(Z = \frac{X - \mu}{s}\)

Z = (23.2262 - 22)/1.45

Z = 0.85

Z = 0.85 has a p-value of 0.8023.

X = 20.6214:

\(Z = \frac{X - \mu}{s}\)

Z = (20.6214 - 22)/1.45

Z = -0.95

Z = -0.95 has a p-value of 0.1711.

0.8023 - 0.1711 = 0.6312 = 63.12%.

The first quartile for the distribution is X when Z = -0.675, hence:

\(Z = \frac{X - \mu}{s}\)

-0.675 = (X - 22)/1.45

X - 22 = -0.675 x 1.45

X = 21.

For item g, the probability is one subtracted by the p-value of Z when X = 829.0774, hence:

\(Z = \frac{X - \mu}{s}\)

Z = (829.0774 - 902)/59.55

Z = -1.22

Z = -1.22 has a p-value of 0.1112.

A shipment of 8 computers contains 3 with defects. Find the probability that a sample of size 2, drawn from the 8, will not contain a defective computer.
What is the probability that a sample of 2 of the 8 computers will not contain a defective computer?
(Type an integer or a simplified fraction.)

Answers

Answer:

5/28

Step-by-step explanation:

First of all, probability is defined as the number of ways a certain event can happen divided by the total ways of an event happening. In this scenario, we are asked to find the number of non-defective computers divided by the total ways that a sample of two can be chosen.

The number of ways to choose 2 computers from 8 can be written as \(8\choose2\), which is equal to \(\frac{8\cdot7}{2}\), which is 28. Now, there are 3 defective computers, for a total of 5 non-defective computers, so the probability is 5/28.

Answers

The sixth term of the geometric sequence is 2048.

The given geometric sequence is 2, 8, 32, 128. We can observe that each term is obtained by multiplying the previous term by 4. Therefore, the common ratio (r) of the sequence is 4.

The formula for the nth term (an) of a geometric sequence is given by:

an = a1 * r^(n-1)

where a1 is the first term and r is the common ratio.

For this sequence, a1 = 2 and r = 4. Plugging in these values into the formula, we get:

an = 2 * 4^(n-1)

To find a6, we substitute n = 6 into the formula:

a6 = 2 * 4^(6-1)

  = 2 * 4^5

  = 2 * 1024

  = 2048

Solve for y c=7(y-k)

Answers

Concept

You are to make y the subject of the formula or subject of the relation.

Next, write the equation and solve for y.

c = 7(y - k)

first, multiply 7 with y and k to remove the bracket.

c = 7y - 7k

Next, move negative 7k to the left of the equation.

c + 7k = 7y

Divide through by 7 to make y subject of the relation.

\(\begin{gathered} We\text{ have} \\ \frac{c\text{ + 7k}}{7}\text{ = y} \\ or \\ y\text{ = }\frac{c}{7}\text{ + }\frac{7k}{7} \\ y\text{ = }\frac{c}{7}\text{ + k} \end{gathered}\)

Final answer

y = c/7 + k or y = (c + 7k) /7

I NEED HELP ASP ITS DUE IN A COUPLE OF HOURS Sorting a poker hand. C PROGRAMMING LANGUAGEThis program asks you to begin implementing a program that runs a poker game. To start, you will need to define two enumerated types:(a) Represent the suits of a deck of cards as an enumeration (clubs, diamonds, hearts, spades). Define two arrays parallel to this enumeration, one for input and one for output. The input array should contain one-letter codes: {c, d, h, s}. The output array should contain the suit names as strings.() Represent the card values as integers. The numbers on the cards, called spot values, are entered and printed using the following one-letter codes: {A, 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K}. These should be translated to integers in the range 1 . . . 13. Any other card value is an error.() Represent a card as class with two data members: a suit and a spot value. In the Card class, implement these functions:Card::Card(). Read and validate five cards from the keyboard, one card per line. Each card should consist of a two-letter code such as 3H or TS. Permit the user to enter either lower-case or upper-case letters.void print().
