The average number of shirts sold in the beach shop was 285 on Saturday in the
summer. As the temperature went lower, the average number of shirts decreased to 114
every Saturday. What was the percentage decrease of in the average number of shirts
sold in the shop?
Answers
Answer:
Decreased by 60%
Step-by-step explanation:
First take the difference to the original amount to the new amount to find the change. 285 - 114 = 171
171/285 = .6
Multiply that by 100 to get it's percent.
The amount of shirts sold decreased by 60%
Final answer:
The percentage decrease in the average number of shirts sold in the shop from 285 to 114 shirts is 60%.
Explanation:
The percentage decrease in the average number of shirts sold at the beach shop can be calculated using the following formula: Percentage decrease = ((Original Average - New Average) / Original Average) × 100. The original average is 285 shirts, and the new average is 114 shirts after the temperature decrease.
So, the calculation would be: ((285 - 114) / 285) × 100 = (171 / 285) × 100 = 0.6 × 100 = 60%.
Therefore, the percentage decrease in the average number of shirts sold in the shop is 60%.
The product of two consecutive odd integers is 1 less than twice their sum. Find the integers.
Answers
Two consecutive odd integers are [tex]2k+1[/tex] and [tex]2k+3[/tex], for some integer [tex]k[/tex].
Their product is [tex](2k+1)(2k+3)=4k^2+8k+3[/tex].
Twice their sum is [tex]2(2k+1+2k+3)=2(4k+4)=8k+8[/tex]
Since the product is 1 less than twice the sum, we have
[tex]\underbrace{4k^2+8k+3}_{\text{the product}}=\underbrace{8k+8}_{\text{twice the sum}}-1[/tex]
So, we have
[tex]4k^2-4=0 \iff 4k^2=4 \iff k^2=1 \iff k=\pm 1[/tex]
If [tex]k=1[/tex], the integers are 3 and 5
If [tex]k=-1[/tex], the integers are -1 and 1.

Use a comma to separate answers.)
Answers
Final answer:
The smallest perimeter for a rectangle with an area of 36 square inches is 24 inches, and the dimensions that achieve this are those of a square, specifically 6 inches by 6 inches.
Explanation:
The smallest perimeter of a rectangle with an area of 36 square inches is achieved when the rectangle is a square because the sides are equal, and a square minimizes the perimeter for a given area. The formula for the area of a square is area = side², so if we have an area of 36 square inches, the side length of the square is √36, which equals 6 inches. Using this side length, we can calculate the perimeter of the square, which is perimeter = 4 × side, giving us a perimeter of 6 inches × 4, which is 24 inches.
The smallest perimeter we can have is 24 inches, and the dimensions of the rectangle (in this case, a square) that give us this smallest perimeter are 6 inches by 6 inches.

How many 5-digit numbers are there that are divisible by either 45 or 60 but are not divisible by 90?
Answers
There are 7,991 5-digit numbers that are divisible by either 45 or 60 but not divisible by 90.
Explanation:To find the number of 5-digit numbers that are divisible by either 45 or 60 but not by 90, we can use the principle of inclusion-exclusion. First, let's find the number of 5-digit numbers divisible by 45 and the number divisible by 60, then subtract the number divisible by 90 to avoid overcounting.
A 5-digit number divisible by 45 must also be divisible by 9 and 5. The smallest 5-digit number divisible by 45 is 10005 (9 * 5 * 445), and the largest is 99990 (9 * 5 * 2222). We can find the number of 5-digit numbers divisible by 45 by subtracting the two numbers and adding 1 (99990 - 10005 + 1).
A 5-digit number divisible by 60 must also be divisible by 12 and 5. The smallest 5-digit number divisible by 60 is 10020 (12 * 5 * 167), and the largest is 99960 (12 * 5 * 833). We can find the number of 5-digit numbers divisible by 60 using the same method as before (99960 - 10020 + 1).
Finally, we subtract the number of 5-digit numbers divisible by 90. A 5-digit number divisible by 90 must be divisible by 45 and 2. The smallest 5-digit number divisible by 90 is 10035 (9 * 5 * 445 and 2 * 5017), and the largest is 99945 (9 * 5 * 2221 and 2 * 49973). Again, we use the same method as before to find the number of 5-digit numbers divisible by 90 (99945 - 10035 + 1).
To find the final answer, we subtract the number of 5-digit numbers divisible by 90 from the sum of the numbers divisible by 45 and 60.

Test-preparation organizations like Kaplan, Princeton Review, etc. often advertise their services by claiming that students gain an average of 100 or more points on the Scholastic Achievement Test (SAT). Do you think that taking one of those classes would give a test taker 100 extra points?
Answers
Answer:
High school students and their parents are often bombarded with SAT test prep applications as they get closer to the college application process. Exam preparation offers arrive in the mail; they are sent home by schools, and they are not cheap. (The Princeton Review "Ultimate Classroom" course costs $ 1,199 in New York City.) When students take these courses and do not see their scores improve, parents may wonder if their children have studied enough or if they have wasted their money.
Step-by-step explanation:
Previous year, the NACAC released a report concluding that exam preparation courses have minimal impact on improving SAT scores: approximately 10-20 points on average in math and 5-10 points on critical reading. The Association for college administration report also noted that this evidence is "contrary to claims made by many test preparation providers of large increases of 100 points or more on the SAT."
Kathleen Steinberg, a College Board spokeswoman, says that, on average, students who take the SAT twice only "increase their scores by about 30 points."
He further disclose that "The College Panel does not indorse taking the SAT more than twice, as there is no evidence to indicate that taking the test more than twice increases grade performance."
Parents might also be surprised at the actual average SAT scores: 501 in critical reading, 515 in math, and 493 in writing, according to Steinberg. (The highest score you can get in any section is 800).
Kaplan claimed that The Princeton Review's claims for score breaks were based on comparing the results of Princeton Review's "diagnostic" tests with the students' self-reported scores on the actual SAT tests, as opposed to SAT scores previous and after.
Final answer:
Test-preparation organizations like Kaplan, Princeton Review, etc. often claim that students gain an average of 100 or more points on the SAT after taking their classes. While it is possible for some students to achieve a significant score improvement after taking these classes, it is important to note that the average improvement may not be 100 points for every student.
Explanation:
Test-preparation organizations like Kaplan, Princeton Review, etc. often claim that students gain an average of 100 or more points on the SAT after taking their classes. While it is possible for some students to achieve a significant score improvement after taking these classes, it is important to note that the average improvement may not be 100 points for every student.
The effectiveness of these classes depends on various factors, such as the student's starting score, their commitment and effort in the class, and their ability to apply the strategies they learn. Some students may experience a smaller improvement, while others may see a larger gain.
It's recommended for students to research and read reviews before choosing a test-preparation organization to ensure they are selecting a reputable program that aligns with their learning style and goals.
What is the measure of each angle in the Summer Triangle
Answers
The measure of each angle in the Summer Triangle depends on the position and alignment of the stars and cannot be determined without specific coordinates and time of observation.
Explanation:The Summer Triangle is a prominent summer asterism formed by three bright stars: Vega, Deneb, and Altair. The measure of each angle in the Summer Triangle depends on the position and alignment of these stars in the sky. The angles cannot be determined without the specific coordinates and time of observation.
Astronomers use angles to measure the separation between celestial objects in the sky. A full circle has 360°, and the half-sphere of the sky from horizon to opposite horizon contains 180°. By measuring the angular separation between two stars or objects, astronomers can determine how far apart they appear in the sky. The angle is typically measured in degrees (°).
For example, if two stars are 18° apart, their separation spans about 1/10 of the dome of the sky. To give you a sense of how big a degree is, the full Moon is about half a degree across, which is similar to the width of your smallest finger (pinkie) seen at arm's length.

A publisher reports that 47%47% of their readers own a personal computer. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 280280 found that 43%43% of the readers owned a personal computer. Make the decision to reject or fail to reject the null hypothesis at the 0.010.01 level.
Answers
Answer:
The null hypothesis was not rejected.
The proportion of readers who own a personal computer is 47%.
Step-by-step explanation:
The claim made by a publisher is that 47% of their readers own a personal computer.
A single proportion z-test can be used to determine whether the claim made by the publisher is authentic or not.
The hypothesis for this test can be defined as follows:
H₀: The proportion of readers who own a personal computer is 47%, i.e. p = 0.47.
Hₐ: The proportion of readers who own a personal computer is different from 47%, i.e. p ≠ 0.47.
The information provided is:
[tex]n=280\\\hat p=0.43\\\alpha =0.01[/tex]
The test statistic is:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}=\frac{0.43-0.47}{\sqrt{\frac{0.47(1-0.47)}{280}}}=-1.34[/tex]
The test statistic value is, z = -1.34.
Decision rule:
If the p-value of the test is less than the significance level α = 0.01 then the null hypothesis will be rejected and vice-versa.
Compute the p-value as follows:
[tex]p-value=2\times P (Z < z)[/tex]
[tex]=2\times P (Z < -1.34)\\=2\times [1-P(Z<1.34)]\\=2\times [1-0.90988]\\=0.18024\\\approx0.18[/tex]
*Use a z table for the probability.
The p-value of the test is 0.18.
p-value = 0.18 > α = 0.01
The null hypothesis was failed to be rejected at 1% level of significance.
Conclusion:
There is enough evidence to support the claim made by the publisher. Hence, it can be concluded that the proportion of readers who own a personal computer is 47%.
A deck of cards contains 52 cards.two decks are put together and divided amount eight players.how many cards does each person get
Answers
Answer:
each person gets 13 cards
Step-by-step explanation:
if each deck contains 52 cards and two of them are put together then it would be 52x2=104 divided by 8=13
When two decks of 52 cards each are combined and divided among eight players, each player receives 13 cards.
If two decks of 52 cards are combined, there would be a total of 104 cards (52 cards per deck × 2 decks). To find out how many cards each person gets when these are divided among eight players, we divide the total number of cards by the number of players:
Calculate the total number of cards: 52 cards/deck imes 2 decks = 104 cards.
Divide this number by the number of players: 104 cards / 8 players = 13 cards/player.
So, each person would receive 13 cards.
Suppose that a recent poll found that 49% of adults believe that the overall state of moral values is poor. Complete parts (a) through (c). (a) For 250 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. The mean of X is nothing. (Round to the nearest whole number as needed.) The standard deviation of X is nothing. (Round to the nearest tenth as needed.)
Answers
Answer:
The mean of X is 122.5 and the standard deviation is 7.9.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
In this problem, we have that:
[tex]n = 250, p = 0.49[/tex]
So
[tex]E(X) = np = 250*0.49 = 122.5[/tex]
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{250*0.49*0.51} = 7.9[/tex]
The mean of X is 122.5 and the standard deviation is 7.9.

They plan to test the hypothesis using a significance level of 0.05 and a sample size of n = 100 cars. It is believed that the population standard deviation is 3 mpg. Based upon this information, if the "true" population mean is 32.0 mpg, what is the probability that the test will lead the consumer group to "accept" the claimed mileage for this car? Question 36 options: About 0.9545 Approximately 0.0455 About 0.45 None of the above
Answers
Answer:
Probability that the test will lead the consumer group to "accept" the claimed mileage for this car is 0.00043.
Step-by-step explanation:
We are given that a consumer group plans to test whether a new passenger car that is advertised to have a mean highway miles per gallon of at least 33 actually meets this level.
It is believed that the population standard deviation is 3 mpg. Based upon this information, the "true" population mean is 32.0 mpg.
Let [tex]\bar X[/tex] = sample mean highway miles per gallon
The z-score probability distribution for sample mean is given by;
Z = [tex]\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = true population mean = 32.0 mpg
[tex]\sigma[/tex] = population standard deviation = 3 mpg
n = sample of cars = 100
The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Now, Probability that a mean highway miles per gallon of at least 33 actually meets this level is given by = P([tex]\bar X[/tex] [tex]\geq[/tex] 33)
P([tex]\bar X[/tex] [tex]\geq[/tex] 33) = P( [tex]\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] [tex]\geq[/tex] [tex]\frac{33-32}{\frac{3}{\sqrt{100} } }[/tex] ) = P(Z [tex]\geq[/tex] 3.33) = 1 - P(Z < 3.33)
= 1 - 0.99957 = 0.00043
The above probability is calculated by looking at the value of x = 3.33 in the z table which has an area of 0.7673.
Therefore, the probability that the test will lead the consumer group to "accept" the claimed mileage for this car is 0.00043.

the second digit from the decimal, round it based on the the thousandth if above 5 round it to the next number 4 and below round it to the same number
Step-by-step explanation:
say for example 10.246 this would round to 10.25
another example is 10.244 this would round to 10.24
Suppose that a hypothesis test is conducted. 12 out of 100 subjects have the necessary qualities. The null hypothesis is that the proportion of the subjects who have the necessary qualities is equal to 0.2, while the alternative hypothesis is that this proportion is less than 0.2. The p-value is 0.023. Using a 5% significance level, state the conclusion to the hypothesis test in context. A : The p-value is less than the significance level, so we reject the null hypothesis. We can conclude that the proportion of the subjects who have the necessary qualities is less than 0.2. B : The p-value is less than the significance level, so we do not reject the null hypothesis. We cannot conclude anything about the proportion of the subjects who have the necessary qualities. C : The p-value is less than the significance level, so we do not reject the null hypothesis. We can conclude that the proportion of the subjects who have the necessary qualities is equal to 0.2. D : The p-value is more than the significance level, so we reject the null hypothesis. We can conclude that the proportion of the subjects who have the necessary qualities is less than 0.2. E : The p-value is more than the significance level, so we do not reject the null hypothesis. We cannot conclude anything about the proportion of the subjects who have the necessary qualities.

Answer:
Option A
The p-value is less than the significance level of 0.05 chosen and so we reject the null hypothesis H0 and can conclude that the proportion of the subjects who have the necessary qualities is less than 0.2.
Step-by-step explanation:
Normally, in hypothesis testing, the level of statistical significance is often expressed as the so-called p-value. We use p-values to make conclusions in significance testing. More specifically, we compare the p-value to a significance level "α" to make conclusions about our hypotheses.
If the p-value is lower than the significance level we chose, then we reject the null hypotheses H0 in favor of the alternative hypothesis Ha. However, if the p-value is greater than or equal to the significance level, then we fail to reject the null hypothesis H0
though this doesn't mean we accept H0 automatically.
Now, applying this to our question;
The p-value is 0.023 while the significance level is 0.05.
Thus,p-value is less than the significance level of 0.05 chosen and so we reject the null hypothesis H0 and can conclude that the proportion of the subjects who have the necessary qualities is less than 0.2.
The only option that is correct is option A.
Answer: A: The p-value is less than the significance level, so we reject the null hypothesis. We can conclude that the proportion of the subjects who have the necessary qualities is less than 0.2.
Step-by-step explanation:
Here, p value = 0.023
significance level = 0.05
As p value < 0.05
