If the polynomial p(x) is divided by (x-1) three times and has a remainder of 1 at the end, then -1 is a double root of p(x). This means that (x+1) is a factor of p(x) raised to the power of 2.

When a polynomial is divided by (x-1), the remainder represents the value of the polynomial at x=1. Since the remainder is 1, it implies that p(1) = 1. Dividing p(x) by (x-1) three times indicates that the polynomial has been factored by (x-1) three times. Consequently, the polynomial can be written as p(x) = (x-1)^3 * q(x) + 1, where q(x) is the quotient obtained after dividing p(x) by (x-1) three times. Since the remainder is 1, it means that when x=1, p(x) leaves a remainder of 1.

Thus, (1-1)^3 * q(1) + 1 = 1, which simplifies to q(1) = 0. This implies that (x-1) is a factor of q(x), meaning that q(x) can be written as q(x) = (x-1) * r(x), where r(x) is another polynomial.

Substituting this into the earlier expression for p(x), we get p(x) = (x-1)^3 * (x-1) * r(x) + 1. Simplifying further, p(x) = (x-1)^4 * r(x) + 1. Now, we can see that p(x) is divisible by (x+1) since (x+1) is a factor of (x-1)^4, and the remainder is 1. Therefore, -1 is a double root of p(x) because (x+1) appears twice in the factored form of p(x).

Based on the given sample data and using a significance level of 0.05, there is sufficient evidence to support the claim that the South Orange district has a better transfer rate than the North Orange district.

The significance level (α) is given as 0.05, which means we are willing to accept a 5% chance of making a Type I error

The sample proportions are calculated as:

p₁ = x₁ / n₁

p₂ = x₂ / n₂

Where:

x₁ = number of successful transfers in the South Orange district = 672

n₁ = total number of former students in the South Orange district = 1000

x₂ = number of successful transfers in the North Orange district = 642

n₂ = total number of former students in the North Orange district = 1000

The test statistic for testing the difference in proportions is the z-score, which is given by the formula:

z = (p₁ - p₂ ) / √[(p(1-p)/n₁) + (p(1-p)/n₂)]

Where:

p = (x₁ + x₂) / (n₁ + n₂)

Substituting the values:

p₁ = 672 / 1000 = 0.672

p₂ = 642 / 1000 = 0.642

p = (672 + 642) / (1000 + 1000) = 0.657

z = (0.672 - 0.642) / √[(0.657(1-0.657)/1000) + (0.657(1-0.657)/1000)]

=19.40

Since the alternative hypothesis is one-sided (p1 > p2), we need to compare the calculated z-score to the critical value of 1.645.

Since 19.40 > 1.645, we reject the null hypothesis.

Answer:

The amount Lilian needs to invest is $5,160

Step-by-step explanation:

The parameters of the amount Lilian is going to invest in an account are;

The interest rate the account pays = 5.7%

The final amount the investment is expected to reach after the given time period = $7,600

The number of years of the investment = 7 years

The formula for compound interest is presented as follows;

\(A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}\)

Where;

A = The final amount = $7,600

P = The amount Lilian is to invest

r = The interest rate = 5.7% = 0.057

n = The number of times the interest is applied per time period = 1

t = The number of period that passes = 7 (years)

Therefore, we get;

\(7,600 = P \cdot \left(1 + 0.057 \right)^{7}\)

∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754

The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

Yes, there is convincing evidence at the 0.01 level that more than 20% of all adults can describe where the humerus bone is located.

To determine if there is convincing evidence, we can conduct a hypothesis test. Let's set up the null and alternative hypotheses. The null hypothesis (H0) is that the proportion of adults who can describe where the humerus bone is located is 20%, while the alternative hypothesis (Ha) is that the proportion is greater than 20%. We can use a one-sample proportion test to analyze the data. Given that the sample size is 100 and the observed proportion is 30.0%, we can calculate the test statistic and compare it to the critical value at the 0.01 significance level. Performing the test, if the calculated test statistic falls in the rejection region (beyond the critical value), we reject the null hypothesis. In this case, since the observed proportion is higher than 20% and the test statistic exceeds the critical value, there is convincing evidence to support the alternative hypothesis that more than 20% of all adults can describe where the humerus bone is located.

The number of Screamers when Runners are 6 is 4,

and the number of Runners when Screamers are 10 is 15.

It is basically the measurement of two numbers and it compares by how much one quantity is bigger than another.

When two ratios are equal, they are usually said to be in proportion.

As given in the above questions,

Screamers:Runners= 2:3

So, let the number of screamers in first case is x

Then, x:6 = 2:3

Step-by-step explanation:

a. the costs of non-compliance, enforcement, prevention and evaluation are -75 d/p, -$7500, $17500 and $5000 respectively

b. The percentage of effort devoted to each component is:

a) To calculate the costs of non-compliance, enforcement, prevention, and evaluation, we need to determine the deviations in effort for each component and multiply them by the corresponding cost per person-day.

Non-compliance cost:

Non-compliance cost = Actual effort - Predicted effort

To calculate the actual effort, we need to sum up the effort for each component mentioned:

Actual effort = Plan development + Software development + Reviews + Tests + Training + Methodology

Actual effort = 25 + 75 + 20 + 30 + 20 + 5 = 175 d/p

Non-compliance cost = Actual effort - Predicted effort = 175 - 250 = -75 d/p

Enforcement cost:

Enforcement cost = Non-compliance cost * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the enforcement cost:

Enforcement cost = -75 * $100 = -$7500 (negative value indicates a cost reduction due to underestimation)

Prevention cost:

Prevention cost = Predicted effort * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the prevention cost for each component:

Plan development prevention cost = 25 * $100 = $2500

Software development prevention cost = 75 * $100 = $7500

Reviews prevention cost = 20 * $100 = $2000

Tests prevention cost = 30 * $100 = $3000

Training prevention cost = 20 * $100 = $2000

Methodology prevention cost = 5 * $100 = $500

Total prevention cost = Sum of prevention costs = $2500 + $7500 + $2000 + $3000 + $2000 + $500 = $17500

Evaluation cost:

Evaluation cost = Total project cost - Prevention cost - Enforcement cost

Evaluation cost = $25000 - $17500 - (-$7500) = $5000

b) To calculate the percentage of effort devoted to each component out of the total cost, we can use the following formula:

Percentage of effort = (Effort for a component / Total project cost) * 100

Percentage of effort for each component:

Plan development = (25 / 250) * 100 = 10%

Software development = (75 / 250) * 100 = 30%

Reviews = (20 / 250) * 100 = 8%

Tests = (30 / 250) * 100 = 12%

Training = (20 / 250) * 100 = 8%

Methodology = (5 / 250) * 100 = 2%

To find the values of the parameters a and c in the parabola with the equation f(x) = ax^2 + c such that the slope of the tangent at x = 1 is 4, you can use the following steps:

Find the derivative of the function f(x). To do this, you will need to use the power rule for differentiation, which states that the derivative of x^n is nx^(n-1). In this case, the derivative of f(x) is 2ax.

Substitute x = 1 into the derivative of the function f(x). This will give you the slope of the tangent line at x = 1.

Set the slope of the tangent line at x = 1 equal to 4. This will give you an equation in terms of a and c.

Solve the equation for a and c. This will give you the values of the parameters a and c that you are looking for.

For example, suppose you have the parabola f(x) = ax^2 + c, and you want to find the values of the parameters a and c such that the slope of the tangent at x = 1 is 4. The derivative of f(x) is 2ax, so substituting x = 1 into this equation gives you the slope of the tangent line at x = 1: 2a(1) = 2a. Setting this equal to 4 gives you the equation 2a = 4, which you can solve for a to get a = 2.

To find the value of c, you can substitute the value of a back into the original equation for the parabola, f(x) = ax^2 + c. For example, if x = 1, then f(1) = (2)(1^2) + c = 2 + c. If you know the value of f(1), you can substitute it into this equation to solve for c.

For example, suppose you know that f(1) = 6. Substituting this value into the equation f(1) = 2 + c gives you 6 = 2 + c, which you can solve for c to get c = 4.

Therefore, the values of the parameters a and c in the parabola with the equation f(x) = ax^2 + c such that the slope of the tangent at x = 1 is 4 are a = 2 and c = 4.

The value of a is 2 and c is f(1)-2.

What is a tangent to a parabola?

The equation of the tangent of the parabola y² = 4ax is y = mx + a/m, where c = a/m. The point of contact is (a/m², 2a/m).

Given here, the equation of the parabola as y= ax²+ c and therefore slope of the parabola is f'x  = 2ax substituting x=1 we should get slope equal to 4 hence 2a=4 or a=2 and again substituting the value of a=2 and at x=1 we get f(1) = 2+c thus c=f(1)-2

Hence, this is the process to find the value of a and c.

Answer:

276.46 in^3

Step-by-step explanation:

See the attached worksheet.  The pencil balloon if formed by a cylinder and cone.  Use the volume formulas for each of these shapes to calculate that shape's contribution to the total volume, and then add them.

The volume of the cylinder portion is 263.9 in^3.

The volume of the cone portion is 12.56 in^3

The sum is 276.46 in^3, which matches the first answer option.

Answer:

276.46 cubic inches

Step-by-step explanation:

Volume of the cylindrical part = πr²h, r= radius, h = height

Volume of a cone  (1/3) πr²h,  r= radius, h = height

For given dimensions

cylinder h = 21, cylinder r = 2

Volume of cylindrical part of balloon = π · 2² · 21 = 4 · 21 · π = 84π cubic inches

Volume of conical part of balloon = (1/3) π · 2² · 3 = 4π

Total volume = 84π + 4π = 88π = 276.46 cubic inches

When the Rhoads family fills their above-ground pool with approximately 3,205 gallons of water, they add a weight of approximately 503,432.61 pounds to the pool.

We can use the given weight of water per gallon to find the total weight of water added to the pool:

Weight of 1 gallon of water = 8.34 pounds

Number of gallons of water in the pool = 3,205 gallons

Radius of the pool = 6 feet (half of the diameter)

Volume of the pool = π × (Radius)^2 × Depth

The depth of the pool is not given, so let's assume it is 4 feet (a common depth for above-ground pools):

Volume of the pool = π × (6 feet)^2 × 4 feet

Volume of the pool ≈ 452.39 cubic feet

Number of gallons of water in the pool = Volume of the pool ÷ 7.48

Number of gallons of water in the pool ≈ 60,381.71 gallons
