The restocking fee for an item with an original price of $180 and a restocking fee of 6% is $10.80.
A restocking fee is a fee that is charged when a customer returns an item, usually to cover the costs associated with processing the return and getting the item back in a sellable condition. The fee is typically calculated as a percentage of the original price of the item.
In this problem, we are given that the restocking fee is 6% and the original price of the item is $180. To find the restocking fee, we can use the formula:
Restocking fee = (Percentage fee / 100) x Original price
In this case, the percentage fee is 6% or 0.06 (since 6% is equivalent to 6/100). The original price is $180. Substituting these values into the formula gives:
Restocking fee = (0.06) x $180
Restocking fee = $10.80

Ken has just retired. His Roth IRA has a present value of $524,856.00 and has an interest rate of 3.4%, compounded annually. In addition, he receives a yearly pension of $32,615.12. Given that Ken plans to draw from his Roth IRA for the next fifteen years, find his total annual income.
Ken total annual income is $ 55,401.98.
What has compounded annually?
The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this.
The completely randomized design, in which participants are assigned to treatment groups at random, is the most basic type of experimental design. The main benefit of using this method is that it minimizes the influence of chance and eliminates bias. This approach makes use of probability theory, which gives statistical analysis a strong foundation.
Given that Roth IRA has a present value of $524,856.00. The rate of interest is 3.4% per annum.
A = P(1+r)^t
A = amount
P = principal
r = rate of interest
t = time
The amount after 15 years is
A = 524,856.00(1+3.4%)¹⁵
A = 866658.9925
The total interest is 866658.9925 - 524,856.00 = $341802.99
The average interest per annum is (341802.99 /15) =22786.866
The annual income is 22786.866 + 32,615.12 = 55,401.986

If the candy store is 6 miles from her school and the straight-line distance between the school and the skate park is 9 miles, how far is the candy store from the skate park? If necessary, round to the nearest tenth
The distance between the candy store and the skate park is about 5.2 miles, with a hypotenuse of 6 miles and a leg of 9 miles, as computed using the Pythagorean theorem.
The candy shop is at the right angle of a triangle made up of Cindy's school, the skate park, and the candy store. Using the Pythagorean theorem, we can calculate the distance between the skate park and the candy shop.
Let's name the separation between the candy shop and the skate park "x" distance. The hypotenuse of the right triangle, the distance between Cindy's school and the candy store, is then 6 miles away, while one of the legs, the skate park, is 9 miles away.
Using the Pythagorean theorem, we can write:
6² = 9² + x²

let's first multiply equating 1 by -3 and then add that to equation 2 :
-3x - 9y - 6z = -24
3x + y + 3z = -10
----------------------------
0 - 8y - 3z = -34
8y + 3z = 34
then multiply equation 1 by 2 and add it to equation 3 :
2x + 6y + 4z = 16

Answer: More green squares. Also 3 blue squares on the rug.
Step-by-step explanation:
The question said the rug is a rectangle. There are also 8 squares on the rug. 4 squares are already taken by green squares. Proof of this is in the fraction itself: 4/8. so out of 8 squares, green occupies 4. We now have 4 squares left.
Purple occupies 1/4. That means we now have 3 squares left. Therefore, the remaining 3 squares are blue.
Answer: 3 blue squares.
In fraction terms, blue occupies 3/8ths of the rectangular rug.
the lower the variability of a set of scores, group of answer choices the less accurately the scores are represented by the mean. the more accurately the scores are represented by the mean. the less consistent the scores are. the more consistently the scores are centered around the median g
The correct answer is "the more accurately the scores are represented by the mean."
The variability or dispersion of a set of scores refers to how spread out the scores are from the central tendency, which is usually measured by the mean, median, or mode.
When a set of scores has low variability or dispersion, it means that the scores are clustered closely together around the mean, and therefore, the mean is a more accurate representation of the typical score in the set.
On the other hand, when a set of scores has high variability or dispersion, it means that the scores are more spread out from the mean, and therefore, the mean may not be a very accurate representation of the typical score in the set. In such cases, other measures of central tendency, such as the median or mode, may provide a more accurate representation of the scores.

natasha wants to average at least 90% in math class. her test scores so far are 94%, 89%, 88%, 92%, and 85%. what score does she need to earn on her next test to reach her goal? show your work.
Hey there! Johnny Sins always here to help,
To find out what score Natasha needs to earn on her next test, we can use the following formula:
Average = (sum of all scores) / number of scores
Let's call the score Natasha needs to earn on her next test "x".
Her average so far is:
Average = (94 + 89 + 88 + 92 + 85) / 5 = 90
Her average after her next test will be:
Average = (94 + 89 + 88 + 92 + 85 + x) / 6
Now, we need to set this equal to 90% and solve for x:
90 = (94 + 89 + 88 + 92 + 85 + x) / 6
90 * 6 = (94 + 89 + 88 + 92 + 85 + x)
540 = (94 + 89 + 88 + 92 + 85 + x)
x = 540 - (94 + 89 + 88 + 92 + 85)
x = 540 - 448
x = 92
So, Natasha needs to earn a 92% on her next test to average at least 90%.

At the level of significance of 0.05, the null hypothesis is not rejected and there is no convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20. Hence, option a. is the accurate answer.
The p-value is the probability of observing a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true. In this case, the null hypothesis is that the proportion of viewers who watch a particular show is equal to or greater than 0.20, and the alternative hypothesis is that the proportion is less than 0.20.
Since the p-value (0.47) is greater than the level of significance (0.05), we fail to reject the null hypothesis. This means that there is not enough evidence to support the claim that the proportion of viewers who watch the show is less than 0.20.
Therefore, we can conclude that at the level of significance of 0.05, the null hypothesis is not rejected. Also, there is no convincing evidence to suggest the true proportion of television viewers who watch the show is less than 0.20.

Which Number line shows all of the values of x that make the inequality true
Any value of x that is less than or equal to -2 will make the inequality true.
What is Number line?
A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every point on a number line is presumed to be a real number, and every real number is assumed to be a point.
To solve the inequality 3x - 1 <= -7, we can start by adding 1 to both sides to isolate the variable:
3x - 1 + 1 <= -7 + 1
Simplifying, we get:
3x <= -6
Next, we can divide both sides by 3 to solve for x:
3x/3 <= -6/3
Simplifying, we get:
x <= -2
This tells us that any value of x that is less than or equal to -2 will make the inequality true. We can represent this on a number line by shading all values less than or equal to -2
The circle at -2 indicates that -2 is included in the solution set, and the arrow pointing to the left indicates that all values less than -2 are also included in the solution set. Therefore, the number line that shows all of the values of x that make the inequality 3x - 1 <= -7 true is the one with all values less than or equal to -2 shaded.
