To find the new price of the jeans after using a 30% off coupon, multiply the original price by the discount percentage and subtract that amount from the original price.
Explanation:To find the new price of the jeans after using the 30% off coupon, you need to multiply the original price by the discount percentage and subtract that amount from the original price. Here's how:
Calculate the discount amount by multiplying the original price ($34.00) by the discount percentage (30% or 0.30). The discount amount is $34.00 * 0.30 = $10.20.Subtract the discount amount from the original price to find the new price of the jeans. $34.00 - $10.20 = $23.80.Therefore, the new price of the jeans after using the coupon is $23.80.

Which correctly compares 4.06 and 4.6?
A) 4.6 < 4.06
B) 4.6 = 4.06
C) 4.06 > 4.6
D) 4.06 < 4.6
Answer:
B is your answer
Step-by-step explanation:
Final answer:
The correct comparison is that 4.06 is less than 4.6 because when looking at the decimal parts, '0.6' (4.6) is greater than '0.06' (4.06).
Explanation:
To compare the numbers 4.06 and 4.6, we need to look at the decimal parts, since the whole number part (4) is the same for both. In the number 4.06, the decimal part is '06', which is actually '0.06' when read as a fraction of the whole number. On the other hand, 4.6 has a decimal part of '6', which is '0.6' as a fraction of the whole number. When comparing '0.6' and '0.06', it is clear that '0.6' is larger because '6' tenths is greater than '6' hundredths.
Therefore, the correct comparison between 4.06 and 4.6 is 4.06 < 4.6, which corresponds to option D in the question.

Tom has a cube a rectangle prism and a triangular prism. Which of these shapes have more than 6 vertical?
The cube and rectangular prism.
Step-by-step explanation:
The triangular prism has 5 and the other two both have 8.
None of the shapes mentioned in the question, a cube, a rectangular prism, or a triangular prism, have more than six faces. For more complex shapes like Icosahedron, they do carry more than six faces.
Explanation:The student's question is about understanding which among the shapes - a cube, a rectangular prism, and a triangular prism - has more than six faces. To answer this, we should first understand that a cube and a rectangular prism (or cuboid) both have 6 faces and a triangular prism also has 5 faces only. Hence, none of these shapes deliver more than 6 faces as specified in the question. For a three-dimensional shape to have more than 6 faces, one has to move towards more complex shapes. For example, the provided reference suggests Icosahedron, a shape with 20 faces is an example of a shape with more than six faces.

Suppose you decided to keep flipping a coin until tails came up, at which
point you would stop. What is the probability of tails coming up on the 4th flip
of the coin? Round your answer to the nearest tenth of a percent.
A. 3.1%
B. 6.3%
C. 1.6%
D. 12.5%
Answer:
B. 6.3%
Step-by-step explanation:
For each time that the coin is tosse, there are only two possible outcomes. Either it comes up tails, or it does not. The probability of coming up tails on a toss is independent of any other toss. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Fair coin:
Equally as likely to come up heads or tails, so [tex]p = 0.5[/tex]
Probability that the first tails comes up on the 4th flip of the coin?
0 tails during the first three, which is P(X = 0) when n = 3.
Tails in the fourth, with probability 0.5. So
[tex]p = 0.5P(X = 0)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]p = 0.5P(X = 0) = 0.5*(C_{3,0}.(0.5)^{0}.(0.5)^{3}) = 0.0625[/tex]
0.0625 * 100 = 6.25%
Rounding to the nearest tenth of a percent, the correct answer is:
B. 6.3%

After simplifying the following rational expression, what is the leading coefficient in the NUMERATOR? [Recall: writing in Standard Form]
Answer:
x
Step-by-step explanation:
We are required to simplify the rational expression:
[tex]\dfrac{4}{x^2+4x-5} -\dfrac{5}{x^2-25}[/tex]
First, we factorize the denominators where possible
[tex]x^2+4x-5=x^2+5x-x-5=x(x+5)-1(x+5)=(x-1)(x+5)\\x^2-25=x^2-5^2 \\$Applying difference of two squares\\x^2-5^2=(x-5)(x+5)[/tex]
Therefore, our rational expression becomes:
[tex]\dfrac{4}{(x-1)(x+5)} -\dfrac{5}{(x-5)(x+5)}\\$Taking LCM\\=\dfrac{4(x-5)-5(x-1)}{(x-1)(x-5)(x+5)}\\=\dfrac{4x-20-5x+5}{(x-1)(x-5)(x+5)}\\=\dfrac{-x-15}{(x-1)(x-5)(x+5)}\\$Factoring out minus in the numerator and -(x-5)=(5-x)\ in the denominator\\=\dfrac{x+15}{(x-1)(5-x)(x+5)}[/tex]
Therefore, the leading coefficient of the numerator is x.

You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Which interval is wider? If convenient, use technology to construct the confidence intervals.
Question:
You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient, use technology to construct the confidence intervals. A random sample of 45 home theater systems has a mean price of $114.00. Assume the population standard deviation is $15.30. Construct a 90% confidence interval for the population mean.
Answer:
At the 90% confidence level, confidence interval = 110.2484 < μ < 117.7516
At the 95% confidence level, confidence interval = 109.53 < μ < 118.48
The 95% confidence interval is wider
Step-by-step explanation:
Here, we have
Sample size, n = 45
Sample mean, [tex]\bar x[/tex] = $114.00
Population standard deviation, σ = $15.30
The formula for Confidence Interval, CI is given by the following relation;
[tex]CI=\bar{x}\pm z\frac{\sigma}{\sqrt{n}}[/tex]
Where, z is found for the 90% confidence level as ±1.645
Plugging in the values, we have;
[tex]CI=114\pm 1.645 \times \frac{15.3}{\sqrt{45}}[/tex]
or CI: 110.2484 < μ < 117.7516
At 95% confidence level, we have our z value given as z = ±1.96
From which we have [tex]CI=114\pm 1.96 \times \frac{15.3}{\sqrt{45}}[/tex]
Hence CI: 109.53 < μ < 118.48
To find the wider interval, we subtract their minimum from the maximum as follows;
90% Confidence level: 117.7516 - 110.2484 = 7.5
95% Confidence level: 118.47503 - 109.5297 = 8.94
Therefore, the 95% confidence interval is wider.
Answer:
B. is the correct option.
With 90% the population mean price is
in lies in (127.01,134.99). With 95% confidence, it can be said that the population mean price lies in ( 126.24,135.76)
Therefore, the 95% confidence interval is wider than 90%.

Which line appears to have the same slope as the equation x-y=4 and has a y-intercept that is 2 units above the y-intercept of the given equation?
Answer:
B
Step-by-step explanation:
First, find the y-intercept form of the equation:
x - y = 4
x - x - y = 4 - x
-y = 4 - x
-y = -x + 4
-y/-1 = -x/-1 + 4/-1 (to get the y positive)
y = x - 4
The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)

Alice had 3 1/4 pounds of flour at the beginning of the week. At the end of the week, she had 2 3/4 pounds. How much has she used?
The amount of flour alice had used at the end of the week is;
Amount = ¹/₂ pounds
Amount of flour she had at the start of the week = 3¹/₄ pounds
Amount she had at the end of the week = 2³/₄ pounds
To solve this, we need to first covert the mixed fractions to improper fractions.Thus;
3¹/₄ pounds = 13/4 pounds
2³/₄ pounds = 11/4 pounds
Thus,
amount of flour she used = amount at the start of week - amount left at end of week
Amount of flour she used = 13/4 - 11/4The denominator is the same and so our solution is to just subtract the numerator and retain the common denominator. This gives;
Amount of flour she used = ¹/₂ pounds

A recipe calls for 1 1/4 cups of sugar for every 3 cups of flour. How much sugar would be needed for 5 cups of flour?
Answer:
[tex]2\frac{1}{12}[/tex] cups of sugar required for 5 cups of flour
Step-by-step explanation:
Number of cups of sugar required for 3 cups of flour =[tex]1 \frac{1}{4}[/tex]
Number of cups of sugar required for 3 cups of flour = [tex]\frac{5}{4}[/tex]
Number of cups of sugar required for 1 cup of flour [tex]=\frac{\frac{5}{4}}{3}[/tex]
Number of cups of sugar required for 5 cups of flour =[tex]\frac{\frac{5}{4}}{3} \times 5[/tex]
Number of cups of sugar required for 5 cups of flour =[tex]\frac{25}{12}[/tex]
Number of cups of sugar required for 5 cups of flour =[tex]2\frac{1}{12}[/tex]

f an investor puts $1500 dollars into an account at an annual rate of 4.8% interest compounded twice a month, how much will they have after two years?
Answer:
They will have $1651 after two years.
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
$1500 dollars into an account at an annual rate of 4.8%
This means that [tex]P = 1500, r = 0.048[/tex]
Interest compounded twice a month.
A year has 12 months.
So 12*2 = 24 compundings, which means that [tex]n = 24[/tex]
How much will they have after two years?
This is A(2).
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(2) = 1500(1 + \frac{0.048}{24})^{24*2} = 1651[/tex]
They will have $1651 after two years.

Use the order of operations to find the value of the expression.
12÷2*3-(7-5)
O A.0
O B.6
O C.16
O D.19
Answer:
C. 16
Step-by-step explanation:
12÷2×3−(7−5) = 16.
I hope this helps!
Following the order of operations (PEMDAS/BODMAS), the expression simplifies as:- 12 ÷ 2 * 3 - (7 - 5) = 6 * 3 - 2 = 18 - 2 = 16. So, the value is 16.
To find the value of the expression 12 ÷ 2 * 3 - (7 - 5), we need to follow the order of operations, often remembered using the acronym PEMDAS (or BODMAS):
1. Parentheses (or Brackets): First, we evaluate what's inside the parentheses. In this case, (7 - 5) equals 2.
2. Exponents (or Orders): There are no exponents or orders in this expression.
3. Multiplication and Division: After dealing with parentheses, we move from left to right. So, 12 ÷ 2 * 3 is calculated as follows:
12 ÷ 2 * 3 = 6 * 3 = 18
4. Addition and Subtraction: Again, we move from left to right. Now we subtract 2 (the result from step 1) from 18 (the result from step 3):
18 - 2 = 16
So, the final answer is 16.
In summary, using the order of operations, the expression simplifies to 16. It's crucial to follow these rules to ensure that mathematical expressions are evaluated correctly, as different orders can lead to different results.

Final answer:
The equation tan^2(x) + 3 = 0 has no real solutions within the given range.
Explanation:
To solve the equation tan^2(x) + 3 = 0, we need to isolate the term with the tangent squared. Subtracting 3 from both sides gives us tan^2(x) = -3. Since the tangent function is positive for angles between 0° and 360°, it is not possible for the square of the tangent to be negative. Therefore, there are no real solutions to this equation, given the specified range of 0 ≦ x < 360°. So, the correct answer is (D) None of the above.
