(a) n= (Round up to the nearest integer.)A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtained if she wishes the estimate to be within 0.03 with 99% confidence if (a) she uses a previous estimate of 0.52? (b) she does not use any prior estimates? (A)n=
The required sample sizes are given as follows:
a) Previous estimate of 0.52: n = 1839.
b) No previous estimate: n = 1842.
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of 0.995, so the critical value is z = 2.575.
The margin of error is given as follows:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
For an estimate of 0.52, the parameters are given as follows:
[tex]M = 0.03, \pi = 0.52[/tex]
Hence the sample size is obtained as follows:
[tex]0.03 = 2.575\sqrt{\frac{0.52(0.48)}{n}}[/tex]
[tex]0.03\sqrt{n} = 2.575\sqrt{0.52 \times 0.48}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.52 \times 0.48}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.52 \times 0.48}}{0.03}\right)^2[/tex]
n = 1839.
Without a previous estimate, the sample size is given as follows:
[tex]0.03 = 2.575\sqrt{\frac{0.5(0.4)}{n}}[/tex]
[tex]0.03\sqrt{n} = 2.575\sqrt{0.5 \times 0.5}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.5 \times 0.5}}{0.03}[/tex]

In 8, substitute each given value of the variable to find which, if any,
is a solution of the inequality.
8. y> 23
y = 20, 23, 25.1, 35
Answer:
Substituting the given values of y in the inequality y > 23:
When y = 20, 20 is not greater than 23, so it's not a solution.
When y = 23, 23 is not greater than 23, so it's not a solution (it's equal).
When y = 25.1, 25.1 is greater than 23, so it's a solution.
When y = 35, 35 is greater than 23, so it's also a solution.
Therefore, the solutions of the inequality are y = 25.1 and y = 35.
DIVIDING INTEGERS. Sarah and Anna both ran five laps of a race. When Anna finished, Sarah was 15 meters behind Anna suppose Sarah fell behind the same number of meters during each lap write an integer that describes how far is Sarah fell behind each lap
Sarah fell behind 3 meters each lap.
What is Total distance?
Whole distance refers to the actual travel distance between the origin and destination locations of the item.
If Sarah was 15 meters behind Anna when Anna finished the race, and they both ran the same distance, we can divide the total distance by the number of laps they ran to find the distance they ran per lap:
Total distance = 5 laps
Distance per lap = total distance / number of laps = 5 laps / 1 = 5
So Sarah and Anna each ran 5 meters per lap. If Sarah fell behind the same number of meters during each lap, we can use a negative integer to describe the distance she fell behind each lap. The distance she fell behind each lap is:
-3 meters (since 3 meters + 3 meters + 3 meters + 3 meters + 3 meters = 15 meters, which is the distance by which she was behind when Anna finished the race).
Therefore, Sarah fell behind 3 meters each lap.

Out of 187 randomly selected adults in the United States who were surveyed, 82 exercise on a regular basis. Construct a 90% confidence interval for the proportion of all adults in the United States who exercise on a regular basis. Round to three decimal places.
The true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493 with 90% confidence interval.
How to construct a confidence interval for the proportion?To construct a confidence interval for the proportion of all adults in the United States who exercise on a regular basis, we can use the formula:
CI = p ± z√(p(1-p)/n)
where:
p = proportion of the sample who exercise on a regular basis
n = sample size
z = z-score from the standard normal distribution corresponding to the desired level of confidence
Here, p = 82/187 = 0.4385 and n = 187.
A standard normal distribution table or calculator, or use the following formula:
z = invNorm((1 + C)/2)
where:
C = confidence level (expressed as a decimal)
invNorm() = inverse normal distribution function
For a 90% confidence level, C = 0.90, so:
z = invNorm((1 + 0.90)/2) = invNorm(0.95) ≈ 1.645
Substituting in the values, we get:
CI = 0.4385 ± 1.645√(0.4385(1-0.4385)/187) ≈ 0.384, 0.493
Therefore, we can say with 90% confidence that the true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493, rounded to three decimal places.

help!! Find the missing length and round it to the nearest tenth.
The length of the hypotenuse is approximately 6.7.
What is the Pythagorean theorem and how is it used to find the hypotenuse of a right triangle?
The Pythagorean theorem is a fundamental relationship in Euclidean geometry that relates the lengths of the sides of a right triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, the Pythagorean theorem can be expressed as:
[tex]c^2 = a^2+ b^2[/tex]
where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.
Finding the missing length :
In the given problem, we are given the lengths of two sides of a right triangle, which are 3 and 6. We can use these values to find the length of the hypotenuse using the Pythagorean theorem:
[tex]h^2 = 3^2+ 6^2[/tex]
[tex]h^2 = 9 + 36[/tex]
[tex]h^2 = 45[/tex]
Taking the square root of both sides gives:
[tex]h = \sqrt{45}[/tex]
Using a calculator, we can simplify this to:
[tex]h \approx 6.7[/tex] (rounded to the nearest tenth)
Therefore, the value of the hypotenuse of the right triangle with sides 3 and 6 is approximately 6.7.

(b) What is Sophia’s Z-score on the Verbal Reasoning section? On the Quantitative Reasoning section? Draw a standard normal distribution curve and mark these two Z-scores.
(c) What do these Z-scores tell you?
(d) Relative to others, which section did she do better on?
(e) Find her percentile scores for the two exams.
(f) What percent of the test takers did better than her on the Verbal Reasoning section? On the Quantitative Reasoning section?
The normal distribution is N(151, 7), the z-score for verbal and quantitative reasoning are 1.29 and 0.52 respectively.
What is the short-hand for these two normal distribution(a) The shorthand for the normal distribution of the Verbal Reasoning section is N(151, 7), where 151 is the mean score and 7 is the standard deviation. The shorthand for the normal distribution of the Quantitative Reasoning section is N(153, 7.67), where 153 is the mean score and 7.67 is the standard deviation.
(b) Sophia’s Z-score on the Verbal Reasoning section is (160-151)/7 = 1.29. Her Z-score on the Quantitative Reasoning section is (157-153)/7.67 = 0.52.
(c) The Z-scores represent how many standard deviations above or below the mean Sophia’s scores are. A Z-score of 1.29 on the Verbal Reasoning section means Sophia’s score is 1.29 standard deviations above the mean score of all test takers. A Z-score of 0.52 on the Quantitative Reasoning section means Sophia’s score is 0.52 standard deviations above the mean score of all test takers.
(d) Sophia did better on the Verbal Reasoning section because her Z-score is higher for that section.
(e) To find the percentile scores, we use the standard normal distribution table. Sophia’s percentile score on the Verbal Reasoning section is the percentage of test takers who scored lower than her. Using the Z-score of 1.29 and the table, we find that her percentile score is approximately 90.7%. Her percentile score on the Quantitative Reasoning section is the percentage of test takers who scored lower than her. Using the Z-score of 0.52 and the table, we find that her percentile score is approximately 69.4%.
(f) To find the percentage of test takers who did better than Sophia on each section, we can use the standard normal distribution table again. For the Verbal Reasoning section, we need to find the area to the right of Sophia’s Z-score of 1.29. Using the table, we find that this area is approximately 9.3%. Therefore, approximately 9.3% of test takers did better than Sophia on the Verbal Reasoning section. For the Quantitative Reasoning section, we need to find the area to the right of Sophia’s Z-score of 0.52. Using the table, we find that this area is approximately 30.4%. Therefore, approximately 30.4% of test takers did better than Sophia on the Quantitative Reasoning section.

The probability of both independent events A and B happening together is P(A n B) = 0.1.
What is meant by probability?
An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur. In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.
Given,
Probability of A, P(A) = 0.2
Probability of B, P(B) = 0.4
P(A U B) = 0.5
We are asked to find P(A n B)
Now we know,
P(A U B) = P(A) + P(B) - P(A n B)
Then,
P(A n B) = P(A) + P(B) - P(A U B) = 0.2 + 0.4 - 0.5 = 0.1
Therefore the probability of both independent events A and B happening together is P(A n B) = 0.1.

A net of a building block is shown below what is the total surface area of the building block
The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.
What is surface area?Surface area is the total exposed area of a three-dimensional object, including the object's base area and lateral area. It is the area of the surface or outer boundary of an object and is measured in units squared such as square meters or square centimeters. Surface area is an important concept in mathematics, physics, and engineering, as it is used to calculate the amount of material needed to construct an object.
The total surface area of the building block can be found by adding the area of the six faces of the block together. To calculate the surface area of the block, we first need to find the area of each face. The six faces of the building block are four rectangular faces and two triangular faces. The area of each rectangular face can be found using the formula A=l×w, where l is the length and w is the width. The area of each triangular face can be found using the formula A=(b×h)/2, where b is the base and h is the height.
By adding the area of each face together, the total surface area of the building block can be found. The total surface area is equal to the sum of the four rectangular faces plus the two triangular faces. The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.

What is parallelograms?A simple quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry. Both sets of opposite sides are parallel and equal in a particular type of quadrilateral known as a parallelogram.
We must demonstrate that the opposing sides of ABCD's parallelogram are parallel.
CBA = DAB (Alternate interior angles)
Alternative interior angles (ABD = BAC; ADC = CBD) (Alternate interior angles)
DCA = ACD (Alternate interior angles)
Considering that AD = BC, we also have:
A + B Equals A + C. (Also on both sides)
AD = BC
Think about the two pairs of sides that are diagonally opposed: AB and CD and AD and BC.
We have these for AB and CD:
Interior angles of a quadrilateral: DAB + ABD + BCD + CDA = 180°; CBA + BAC + ADC + DCA = 180°. (Substituting corresponding angles)
We may insert them in and simplify to get: since DAB = CBA and ABD = BAC.
BCD = ADC
As a result of having the same transversal CD and equal alternative interior angles, AD and BC are also parallel. As a result, we have demonstrated that ABCD's opposing sides are parallel, proving that ABCD is a parallelogram.

11. Jenn bought 4 identical book
bags online for a total cost of
$95.65 including a flat ate of
$4.99 for shipping. Write an
equation to find the cost of each
book bag, b.
Answer:
Step-by-step explanation:
Let x be the cost of each book bag. Then, we can set up the following equation based on the information given:
4x + 4.99 = 95.65
Here, 4x represents the cost of the four identical book bags, and 4.99 is the flat rate for shipping. We add them up to get the total cost of $95.65.
To solve for x, we can first subtract 4.99 from both sides of the equation to isolate the term 4x on the left-hand side:
4x = 90.66
Then, we can divide both sides of the equation by 4 to solve for x:
x = 22.67
Therefore, each book bag costs $22.67.

Write the equation of the trigonometric graph. Use a positive coefficient on cosine for this activity.
The required equation of the trigonometric graph is y = 2cos[(π/8)(x-2)-2] which represents the cosine function.
What is the cosine function?The cosine function has a range of values between -1 and 1, and it is a periodic function that repeats every 2π radians or 360 degrees.
The graph of the cosine function is a wave-like curve that oscillates between -1 and 1, with a period of 2π radians or 360 degrees.
As we can see, the function's behavior repeats itself. In terms of the form of the function, we may select any interval of length 2π and the following interval of length 2π will be equal to the previous one.
Here, y = 2cos[(π/8)(x-2)-2]
Thus, the equation of the trigonometric graph is y = 2cos[(π/8)(x-2)-2] which represents the cosine function.

Tic-tac-toe: In the game of tic-tac-toe, if all moves are performed randomly the probability that the game will end in a draw is 0.127. How is 0.127 figured in this problem?
There are 5 methods to determine which player has less pieces, 5! ways probability to arrange the Xs, and 4! ways to order the Os, for a total of 5 x 5 x 4! = 28,800 possible games.
What is probability?Calculating the chance that an event will occur or a statement will be true is the subject of probability theory, a branch of mathematics. A risk is a number between 0 and 1, where 1 denotes certainty and a probability of about 0 denotes the likelihood that an event will occur. The likelihood that an event will take place is mathematically expressed as probability. Probabilities can also be expressed as percentages ranging from 0% to 100% or as integers between 0 and 1. the proportion of equally plausible possibilities that actually happen in relation to all possible outcomes when a certain event occurs.
Case 1: There are 5 Xs and 4 Os on the board, and there is a one-point difference in the number of Xs and Os. In this situation, starting with the player who has less pieces on the board, we must alternately put the Xs and Os in the squares. There are 5 methods to determine which player has less pieces, 5! ways to arrange the Xs, and 4! ways to order the Os, for a total of 5 x 5 x 4! = 28,800 possible games.
