To make a profit of 20% the article should be sold for $12.1
How to calculate the new selling priceThe new selling price will be solved by comparing the percentage increment with the old selling price
The selling price is $10.8 and the profit is 8%
The cost of the item is gotten from the profit percent as below
10.8 * 0.08 = 0.864 (profit)
cost price + profit = selling price
cost price = selling price - profit
cost price = 10.8 - 0.864
cost price = 9.936
comparing the percentages
8% profit is 0.864, 20% profit will be
8 = 0.864
20 = ?
cross multiplying
8 * ? = 20 * 0.864
? = 2.16
The new selling price
= cost price + profit
= 9.936 + 2.16
= 12.096 approximately $12.1

I thought of a 3 digit number. Each digit i the quare of the digit to the right. What i my number?
The answer to the given question is 111.
The complete question might be as follows:
I thought of a 3 digit number. Each digit is the square of the digit to the right. What is my number?
= x*100 + y*10 + z.
Requirements:
y = z^2
x = y^2.
Now we shall start to give values to z. Let us start with zero.
If z = 0, then: y = 0^2 = 0, then: x = 0^2 = 0. Then the number would be 0*100 + 0*10 + 0 = 0. This is not a 3 digit number.If z = 1, then: y = 1^2 = 1, then: x = 1^2 = 1. Then the number would be 1*100 + 1*10 + 1 = 111. This is a 3 digit number.If z = 2, then: y = 2^2 = 4, then: x = 4^2 = 16. Then the number would be 16*100 + 4*10 + 2 = 1642. This is not a 3 digit number. This happened because the first digit (x) is not a single digit number.So, values of z which are equal or larger than 2 can be eliminated.Hence, for the question: I thought of a 3 digit number. Each digit is the square of the digit to the right. What is my number? The answer is 111, because the 3 digit number that would fit the requirements mentioned is only 111.

The sampling distribution of the sample mean will always have the same _________ as the original distribution.
The sampling distribution of the sample mean will always have the same the mean of the original non-normal distribution, as the original distribution.
What is distribution?
Each of these samples contains a mean, and if we add up all of the means, we can construct a probability distribution that explains the distribution of the means. As long as we have sufficient samples, as will be discussed later, this distribution is always normal and is referred to as the sampling distribution of the sample mean.
Since the sample mean's sampling distribution is normal, we can naturally calculate the distribution's mean and standard deviation and utilise that information to analyse probability questions.
Here, The sample variance is equal to the population variance divided by the sample size if the population is infinite and the sampling is random, or if the population is finite but we are sampling with replacement.
So we need to use the mean of non-normal distribution.
Hence the answer will be the mean of the original non-normal distribution.

Commute times in the U.S are heavily skewed to the right We select random sample of 500 people from the 2000 U.S, Census who reported a non-zero commute time: In this sample the mean commute time is 27.6 minutes with standard deviation of 19.6 minutes: Are researchers able to conclude from this data that the mean commute time in the U.S.is less than half an hour? Conduct a hypothesis test at the 5% level of significance using an online applet (directions) or calculating and using the T-Distribution Calculator above. Based on your hypothesis test; what can we conclude? Nothing: The distribution of the variable in the population is heavily skewcd, s0 the conditions for use of t-model are not met We cannot trust that the p-value accurate for this reason: With mean ol 27.6 minutes, the data supports the clalm that the average commute time Is less than 30 minutes, but the difference is not statistically significant We fail to reject the null hypothesis that the mean commute time in the U.S, in the year 2000 was 30 minutes: With a mean of 27.6 minutes the data supports the claim that the average commute time is significantly less than 30 minutes We reject the null hypothesis that the mean commute time in the U.S.in the year 2000 was 30 minutes
We conclude that the mean commute time in the U.S. is less than half an hour.
We are given that a random sample of 500 people from the 2000 U.S. Census is selected who reported a non-zero commute time.
In this sample the mean commute time is 27.6 minutes with a standard deviation of 19.6 minutes.
Let = mean commute time in the U.S..
So, Null Hypothesis, : [tex]H_0:[/tex] μ ≥ 30 minutes {means that the mean commute time in the U.S. is more than or equal to half an hour}
Alternate Hypothesis, : [tex]H_A[/tex]: μ < 30 minutes {means that the mean commute time in the U.S. is less than half an hour}
The test statistics that would be used here One-sample t-test statistics as we don't know about population standard deviation;
T.S. = (X -μ)/[tex]{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, X = sample mean commute time = 27.6 minutes
s = sample standard deviation = 19.6 minutes
n = sample of people from the 2000 U.S. Census = 500
So, the test statistics = (27.6 - 30)/[tex]\frac{19.6}{\sqrt{500} }[/tex] ~ [tex]t_4_9_9[/tex]
= -2.738
The value of t test statistic is -2.738.
Also, P-value of test statistics is given by the following formula;
P-value = P( [tex]t_4_9_9[/tex] < -1.645)
Since, we know that at large sample size, the t distribution follows like normal distribution, that means;
P( [tex]t_4_9_9[/tex] < -1.645) = P(Z < -1.645) = 1 - P(Z ≤ 1.645)
= 1 - 0.95002 = 0.04998
Now, at 5% significance level the t table gives critical values of -1.645 at 499 degree of freedom for left-tailed test.
Since our test statistic is less than the critical value of t as -2.378 < -1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.
Therefore, we conclude that the mean commute time in the U.S. is less than half an hour.

11. Trey drained 12 quarts of water from a cooler after a camping trip. The graph shows the remaining quarts of water as a linear function of x, the time in minutes. Which best represents the domain and range of the function?
Answer:
The domain is the time, in minutes from 0 to however long it takes to drain the cooler.
The range is from 12 quarts water to empty.
Step-by-step explanation:
I don't see a graph, but will use the given information to identify a domain and range for the information provided.
The domain is the range of values that are possible for the x axis. In this case, the x axis it time, in minutes. If we set x as the time, in minutes, that the water has been draining, time = 0, is the start of the process.
The y axis, the range, starts at 12 quarts at time = 0. It then decreases with time until the cooler is empty. The range of the function is thus 12 quarts to 0 quarts: Full to empty.
If we knew the actual rate that the cooler drains (e.g., quarts/minute), we could estabish an upper limit to the domain. If a graph were shown of the data, this rate could be calculated and an upper end to the domain could be set. If the rate were 2 quarts/minute, the upper end of the domain would be (12 quarts/2 quarts/minute) = 6 minutes. The domain would be 0 - 6 minutes.

Seventy percent of the time, the length of time to find a parking space takes more than 4 minutes.
For a normally distributed set of data, given the mean and standard deviation, the probability of having the data less than a value can be determined by solving the z-score and using the z-table.
If the probability is 70%, then, using the z-table, the z-score would be -0.52485.
at p = 1 - 0.70 = 0.30 z = -0.52485
Using the formula for finding the z-score, solve for the data value, x.
z-score = (x – μ) / σ
where x = individual data value
μ = mean = 5
σ = standard deviation = 2
z-score = (x – μ) / σ
-0.52485 = (x - 5) / 2
x - 5 = -1.0497
x = 3.9503

is the maximum value of extreme values for the given polynomial.
What is extreme value?
According to the Extreme Value Theorem, if a function is continuous on the interval [a, b], it must have a maximum and a minimum on that range.
Consider, the given function
f(x) = 5x^2 - 8x + 12 ..(1)
Since, if y = f(x) is a function, then the value of x where f'(x) is zero is called extreme value.
Differentiate equation (1) with respect to x.
10x - 8 = 0
10x = 8
x = 8/10
x = 4/5
Plug x = 4/5 in equation (1),
Therefore, is the maximum value of extreme values for the given polynomial.

Step-by-step explanation:
What does it mean to hypothesize that autism is a quantitative trait normally distributed in the population?.
To hypothesize that autism is a quantitative trait normally distributed in the population.
Hypothesis that autism is a quantitative trait normally distributed in the population is actually showing the assumption that we can calculate the level of autism in the population in numbers as well as it is present in everyone at some level just like weight.
There are two types of data:
• Quantitative: Any information that can be counted is referred to as quantitative data and is given a numerical value. You can find out “how many,” “how much,” or “how often” using quantitative variables.
• Qualitative: Qualitative information is descriptive in character and communicated verbally as opposed to numerically.
Hence, here they are assuming that we can measure the level of autism in the population.

Is it possible to form a triangle with side lengths 3. 5, 3. 5, and 9? if so, will it be scalene, isosceles, or equilateral?.
Triangles with the provided side lengths of 3.5, 3.5, and 9 cannot be formed.
According to the Properties of triangle, the length of the third side of a triangle must be greater than the sum of any two of a triangle's sides.
Given the side lengths are 3.5, 3.5 and 9;
Sum of two sides = 3.5 + 3.5 = 7 cannot exceed 9
Thus, it is clear that a triangle cannot be formed using the specified side lengths of 3.5, 3.5, and 9.

Solve this.
15 = x/6 - 1
A) x=96
B) x=90
C) x=84
D) x=80
The value of x in the algebraic expression is option A 96.
Given,
The algebraic expression; 15 = x/6 - 1
We have to solve the expression and find the value of x.
Here,
15 = x/6 - 1
First solve the right hand side
x/6 - 1 = (x - 6) / 6
Now,
15 = (x - 6) / 6
Multiply both sides with 6.
15 × 6 = (x - 6) × 6 / 6
90 = x - 6
Now add 6 to both sides
90 + 6 = x - 6 + 6
x = 96
That is,
The value of x in the algebraic expression is option A 96.
