Answer: $15

Step-by-step explanation:

If you have a 70% coupon for a $50 item, that means you are only paying 30% of the normal price.

0.3 x 50 = 15

The item will cost $15

The fraction nonconforming for this sample is 0.112, or 11.2%.

This is the value that the QC inspector can use to create a p-chart for analyzing the gears' non-conformance.

To calculate the fraction nonconforming, we'll use the following formula:
Fraction nonconforming = Number of nonconforming items / Total sample size
In this case, the number of nonconforming items is 28 gears, and the total sample size is 250 gears.

Now, let's plug in the numbers:
Fraction nonconforming = 28 / 250
Now, we'll divide 28 by 250:
Fraction nonconforming = 0.112

In summary, the voltage across each bulb is 13.75V, the resistance of each bulb is 24.55Ω, and the power dissipated in each bulb is 7.7W.

When eight identical lights are connected in series across a 110-V line, the voltage across each bulb will be 110/8 = 13.75 V.
To find the resistance of each bulb, we can use Ohm's law, which states that resistance is equal to voltage divided by current (R = V/I). Therefore, the resistance of each bulb is 13.75/0.56 = 24.55 ohms.
To find the power dissipated in each bulb, we can use the formula P = VI, where P is power, V is voltage, and I is current. Therefore, the power dissipated in each bulb is 13.75 x 0.56 = 7.7 watts.
To find the voltage across each bulb, divide the total voltage by the number of bulbs:

Voltage across each bulb = Total Voltage / Number of Bulbs = 110V / 8 = 13.75V per bulb

Next, use Ohm's Law to find the resistance of each bulb:

Resistance (R) = Voltage (V) / Current (I) = 13.75V / 0.56A = 24.55Ω per bulb

Finally, find the power dissipated in each bulb using the formula:

Power (P) = Voltage (V) x Current (I) = 13.75V x 0.56A = 7.7W per bulb

a) The probability that a simple random sample of 50 ten-gram portions results in a mean of at least 3.6 insect fragments is approximately 0.027.

b) This result is somewhat unusual, as only about 2.7% of samples would be expected to have a mean of at least 3.6 insect fragments. However, it is not necessarily a cause for concern, as it is within the range of expected variation.

c) More information about the distribution of insect fragments in the population and the context in which the samples were collected would be needed to draw more definitive conclusions.

To answer this question, we would need to know the distribution of insect fragments in the population from which the samples are drawn. Let's assume that this distribution is approximately normal with a mean of 3.2 insect fragments and a standard deviation of 0.8 insect fragments, as suggested by FDA guidelines for chocolate.

The distribution of the sample means for samples of size n can be approximated by a normal distribution with mean µ and standard deviation σ/√n. In this case, µ = 3.2 and σ/√n = 0.8/√50 = 0.113.

To find the probability that a sample of 50 ten-gram portions has a mean of at least 3.6 insect fragments, we need to find the area under the normal curve to the right of 3.6. Using a standard normal distribution table or a calculator, we find that this probability is approximately 0.027.

This result is somewhat unusual, as only about 2.7% of samples would be expected to have a mean of at least 3.6 insect fragments.

Volume of a sphere is given by the formula

It will take Tom and Nelson 1.875 hours, or 1 hour and 52.5 minutes, to complete the report working together.

To solve this problem, we can use the concept of work done. Let's assume that a report is a unit of work, and Tom and Nelson each do a fraction of the work in one hour.

Tom can do the entire report in 3 hours, which means he can do 1/3 of the report in one hour. Similarly, Nelson can do 1/5 of the report in one hour.

If they work together, the fraction of the report they can do in one hour is the sum of their individual fractions:

1/3 + 1/5 = 8/15

So, together they can do 8/15 of the report in one hour. To find out how long it will take them to do the entire report working together, we can use the formula:

time = work ÷ rate

where work is 1 (the whole report) and rate is 8/15 (the fraction of the report they can do in one hour).

time = 1 ÷ (8/15)

time = 1.875 hours

Therefore, it will take Tom and Nelson 1.875 hours, or 1 hour and 52.5 minutes, to complete the report working together.

(a) True. We can use partial fraction decomposition to write X(x² + 4)/(x² - 4) as (A/(x+2)) + (B/(x-2)).

(b) True. We can use partial fraction decomposition to write X² + 4/(x(x² - 4)) as (A/x) + (B/(x+2)) + (C/(x-2)).

(c) True. We can use partial fraction decomposition to write X² + 4/(x²(x - 4)) as (A/x²) + (B/x) + (C/(x-4)).

(d) False. We can use partial fraction decomposition to write X² - 4/(x(x² + 4)) as (A/x) + (Bx+C)/(x²+4).

(a) We want to write X(x² + 4)/(x² - 4) in the form (A/(x+2)) + (B/(x-2)). First, we find A and B by multiplying both sides by the common denominator (x+2)(x-2):

X(x² + 4) = A(x-2) + B(x+2)

Expanding both sides gives:

Xx² + 4X = Ax - 2A + Bx + 2B

Grouping terms by x gives:

Xx² + (A+B)x + (-2A+2B) = 4X

Now we have a system of two equations:

A + B = 0 (coefficients of x)

-2A + 2B = 4X (constant terms)

Solving for A and B gives:

A = -B

-2A + 2B = 4X

-2A + 2(-A) = 4X

-4A = 4X

A = -X

Therefore, B = X. Thus,

X(x² + 4)/(x² - 4) = (-X/(x+2)) + (X/(x-2))

(b) We want to write X² + 4/(x(x² - 4)) in the form (A/x) + (B/(x+2)) + (C/(x-2)). First, we find A, B, and C by multiplying both sides by the common denominator x(x+2)(x-2):

X² + 4 = A(x+2)(x-2) + Bx(x-2) + Cx(x+2)

Expanding both sides gives:

X² + 4 = Ax² - 4A + Bx² - 2Bx + Cx^2 + 2Cx

Grouping terms by powers of x gives:

(X² + 4) = (A+B+C)x² + (-2B+2C)x - 4A

Now we have a system of three equations:

A + B + C = 0 (coefficients of x²)

-2B + 2C = 0 (coefficients of x)

-4A = 4 (constant terms)

Solving for A, B, and C gives:

A = -1/4

B = 1/4

C = 1/4

Therefore,

X² + 4/(x(x² - 4)) = (-1/(4x)) + (1/(4(x+2))) + (1/(4(x-2)))

(c) We want to write X² + 4/(x²(x - 4)) in the form (A/x²) + (B/x) + (C/(x-4)). First, we find A, B, and C by multiplying both sides by the common denominator x²(x-4):

X²(x-4) + 4x² = Ax(x-4) + Bx²(x-4) + Cx²

Expanding both sides gives:

X²x - 4X² + 4x² = Ax² - 4Ax + Bx³ - 4Bx² + Cx²

Grouping terms by powers of x gives:

(X² + 4) = (B)x³ + (A-4B)x² + (-4A+C)x

Now that we have a common denominator of (x² - 4), we can combine the two fractions and simplify:

X(x² + 4) - 2(x² - 4) = A(x - 2) + B(x + 2)

Expanding and simplifying the left side:

x³ + 4x - 2x² + 8 = Ax - 2A + Bx + 2B

Grouping the like terms on each side:

x³ - 2x² + Ax + Bx + 4x - 2A + 2B + 8 = 0

Now we have a polynomial equation that we can use to solve for A and B. We can do this by equating the coefficients of like terms on both sides. Specifically, we can equate the coefficients of x² and x:

x³ - 2x² + Ax + Bx + 4x - 2A + 2B + 8 = 0

Coefficients of x²: -2 = A

Coefficients of x: 4 = B

Therefore, we have:

X(x² + 4)/(x² - 4) = (-2x)/(x² - 4) + (4)/(x² - 4)

The assumption that should not be met before conducting an independent groups t-test is that the samples should have the same number of participants.

An independent groups t-test is a statistical test used to compare the means of two independent groups of data. Before conducting this test, there are several assumptions that should be met to ensure the validity of the results. The first assumption is that the dependent variable should be measured on at least an interval level scale.

This means that the values of the dependent variable should be meaningful and can be compared using mathematical operations such as addition and subtraction. The second assumption is that the dependent variable scores should be normally distributed in their parent populations. This means that the distribution of scores should resemble a bell-shaped curve, with most scores clustering around the mean and fewer scores at the tails.

The third assumption is that the samples should be randomly selected to ensure that the sample is representative of the population from which it was drawn. The fourth assumption is that the samples should have approximately equal variances to ensure that the test is not biased towards one sample over the other. If any of these assumptions are violated, the results of the t-test may not be reliable.

The compound interest investment earns more interest than the simple interest investment, and the difference becomes more significant over time.

After 10 years, the difference is relatively small, but after 20 years, the compound interest investment has earned over $3,700 more than the simple interest investment.

To calculate the amount after 10 and 20 years, we can use the following formulas:

Simple Interest: A = P * (1 + r * t)

Compound Interest: A = P * (1 + r/n)^(n*t)

Where:

Using these formulas and the information given in the table, we can calculate the amount after 10 years and 20 years for each type of investment.

For simple interest, the interest is not compounded, so we just add the interest to the principal:

Amount after 10 years: A = $50,000 * (1 + 0.0275 * 10) = $68,750

Amount after 20 years: A = $50,000 * (1 + 0.0275 * 20) = $87,500

For compound interest, we need to use the formula above with n=12 (since the interest is compounded monthly):

Amount after 10 years: A = $50,000 * (1 + 0.0275/12)^(12*10) = $68,704.23

Amount after 20 years: A = $50,000 * (1 + 0.0275/12)^(12*20) = $91,262.47

To compare the two investments, we can look at the difference between the amounts after 10 and 20 years:

Difference after 10 years: $68,750 - $68,704.23 = $45.77

Difference after 20 years: $87,500 - $91,262.47 = $3,762.47

Since quadrilateral H'I'J'K' is a translation of quadrilateral HIJK, the translation rule include the following: (x, y)  → (x - 8, y + 10).

In Mathematics, the translation of a graph to the left is a type of transformation that simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation of a graph to the right is a type of transformation that simply means adding a digit to the value on the x-coordinate of the pre-image.

By translating the pre-image of quadrilateral HIJK horizontally left by 8 units and vertically up by 10 units, the coordinate J of quadrilateral H'I'J'K' include the following:

(x, y)                               →                  (x - 8, y + 10)

J (8, -2)                        →                  (8 - 8, -2 + 10) = J' (0, 8).
