Answer:
The price of the meal after the discount was (A)$48.11 and the final price of the meal was (B)$57.73.
Step-by-step explanation:
Let us consider the amount of money $56.60 as the cost of the meal.
So the amount of money is 56 dollars and 60 cents.
A: The family has a 15% off coupon.
Discount = 15% of 56.60=0.15x56.60=8.49
Now we subtract the discount amount from the original amount.
Cost of the meal = 56.60-8.49=48.11
So the final price of the meal for the family is $48.11 or 48 dollars and 11 cents.
B: The family gave a tip of 20%.
Amount of money tipped= 20% of 48.11=0.20 x 48.11=9.622
To get the final amount we add the tip to the discounted price.
The final cost of the meal= 48.11+9.622=57.732=57.73
Therefore the family paid a total of 57 dollars and 73 cents for the final cost of the meal after the discount and tip.

Answer: x^4
Step-by-step explanation:
1. Rewrite the expression in fraction form:
(3√x²)^6 = x^(2/3)^6
2 is the exponent, so when written in fraction form, it is the numerator. 3 is the index or root, so in fraction form it is the denominator.
2. Solve:
x^(2/3)^6 = x^(12/3) = x^4
Because the exponent 2/3 is raised to the power of 6, you can use the power rule, which basically just means that whenever an exponent is raised to an exponent, multiply them. So, 2/3 * 6 equals 12/3, and 12/3 equals 4, making your answer x^4.
Zoe is a high school basketball player. In a particular game, she made some free throws (worth one point each) and some two point shots. Zoe made a total of 11 shots altogether and scored a total of 15 points. Write a system of equations that could be used to determine the number of free throws Zoe made and the number of two point shots she made. Define the variables that you use to write the system.
13 number of free throws made and 4 number of two-point shots made.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x represents the number of free throws made (1 point each)
y represents the number of two-point shots made (2 points each)
Zoe made a total of 11 shots, this is written as:
x+y=11...(1)
She made a total of 15 points
x+2y=15..(2)
Subtract (2) from (1)
x+y-x-2y=11-15
-y=-4
y=4
Now plug y value in equation (1)
x+4=11
x=11-4
x=13
Hence 13 number of free throws made and 4 number of two-point shots made.

Kendrick attends a private school where he must wear a uniform. Last year, the price of the uniform was $52. This year's uniform price was $65. What is the percent of increase in the cost of the uniform?
The percent increase in the cost of the uniform from last year to this year is 25%.
What is the percent of increase in the cost of the uniform?To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.
The difference between this year's price and last year's price is:
$65 - $52 = $13
The original price (last year's price) is $52.
So the percent increase in the cost of the uniform is:
percent increase = (difference / original price) x 100
percent increase = ($13 / $52) x 100
percent increase = 0.25 x 100
percent increase = 25%
Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

For each sample, the groups construct a 90% confidence interval to estimate the population mean.Which confidence interval will have greater precision (smaller width) for estimating the population mean?Group of answer choicesThe confidence interval based on the sample of 49 data values will be more precise.Both confidence intervals will have the same precision.The confidence interval based on the sample of 81 data values will be more precise.
The confidence interval for the second group's estimate of the population mean will be more accurate due to the increased sample size.
What is mistake, exactly?
An error is an inaccurate or improper action (from the Latin error, meaning "wandering"). An error is often used interchangeably with the word mistake.
Detailed explanation:
margin of a confidence interval's error:
The following format describes the equation for a confidence interval's margin of error:
M=zα/√n
where is the population's standard deviation, n is the sample size, and z is connected to the confidence level.
This suggests that a larger size results in a better degree of interval precision, or a smaller margin of error.
In this instance:
There are 49 data values in the sample from the first group survey and 81 from the second group.
The confidence interval for the second group's estimate of the population mean will be more accurate due to the increased sample size.

The circumference () C of a circle is 18 18 centimeters. Which formula can you use to find the radius () r if you know that =2π C = 2 π r ? CLEAR CHECK =2π r = C 2 π =2π r = 2 C π =π2 r = π C 2 =2π
The formula to find the radius (r) of a circle when you know the circumference (C) is r = C/(2π).
The formula presented derived from the formula for the circumference of a circle, which is C = 2πr. By rearranging the equation and isolating the radius (r) on one side, we get r = C/(2π).
So, if the circumference (C) of a circle is 18 centimeters, you can use the formula r = C/(2π) to find the radius (r). Plugging in the given value for the circumference (C), we get:
r = 18/(2π)
Simplifying the equation gives:
r = 9/π
Therefore, the radius (r) of the circle is 9/π centimeters.
In conclusion, the formula you can use to find the radius (r) of a circle when you know the circumference (C) is r = C/(2π).

Determine the number of zeros, counting multiplicities, of the following polynomials inside the circle [z] = 1. a.) Z^5-4z^4+z^2+1
To determine the number of zeros, counting multiplicities, of the polynomial \(f(z) = z^5 - 4z^4 + z^2 + 1\) inside the circle \([z] = 1\), we can apply the Argument Principle.
The Argument Principle states that the number of zeros of a function inside a closed curve is equal to the change in argument of the function around that curve divided by \(2\pi\).
Let's consider the function \(g(z) = z^5 - 4z^4 + z^2 + 1\) and find the number of zeros inside the unit circle \([z] = 1\) by calculating the change in argument.
First, we need to find the zeros of \(g(z)\) by solving \(g(z) = 0\):
\[z^5 - 4z^4 + z^2 + 1 = 0\]
Unfortunately, this equation does not have a closed-form solution, so we need to use numerical methods to approximate the zeros.
Using numerical methods, we find that \(g(z)\) has two zeros inside the unit circle: \(z_1 \approx 0.1789\) and \(z_2 \approx 0.8436\).
Since \(f(z)\) has the same zeros as \(g(z)\), the number of zeros of \(f(z)\) inside the unit circle is also two, counting multiplicities.

Archaeopteryx often is referred to as a transitional fossil because its fossils suggest that it is an intermediate organism between dinosaurs and birds. Transitional forms in the fossil record, such as Archaeopteryx, provide evidence for which pattern of evolution
Transitional forms in the fossil record, including Archaeopteryx, provide evidence for the pattern of evolution known as "gradualism."
This pattern suggests that species change over time through a slow and continuous process of accumulation of small, incremental changes. Transitional fossils like Archaeopteryx exhibit characteristics that are intermediate between two different groups of organisms, indicating a gradual transition from one form to another.
The presence of transitional fossils supports the idea that species do not undergo abrupt transformations but instead evolve gradually over long periods of time.
These fossils provide a tangible link between different groups of organisms, such as dinosaurs and birds in the case of Archaeopteryx, and offer evidence for the gradual transformation of one group into another. This supports the broader concept of evolution as a slow and continuous process of change in populations over generations.

Keyboard instruments like the organ are not easily classified within any of the four Western instrument families.
Keyboard instruments like the organ are unique due to their unique characteristics and unique sound production methods. They produce sound through air passing through pipes, making them challenging to classify within traditional Western instrument families.
Keyboard instruments like the organ are not easily classified within any of the four Western instrument families because they have unique characteristics that make them distinct. The four main Western instrument families are strings, woodwinds, brass, and percussion. However, keyboard instruments like the organ do not fit neatly into any of these categories.
The reason for this is that keyboard instruments produce sound by pressing keys that activate mechanisms to generate sound vibrations. The organ, for example, produces sound through the use of air passing through pipes when keys are pressed. This mechanism is different from the way strings, woodwinds, brass, and percussion instruments produce sound.
Furthermore, keyboard instruments like the organ can produce a wide range of sounds and can be used to play different types of music. This versatility makes them unique and challenging to classify within the traditional Western instrument families.
