The expression that can be used to determine the average number of people that watch each free movie is -

y = - 81x⁴ - 405x³ - 216x² + 660x - 281x³ - 1485x² - 792x + 2420

An algebraic expression is a combination of terms both constants and variables. For example -

2x + 3y + z

3x + y

Given is that a movie website offers one free movie viewing to anyone that registers. The total number of people that register can be modeled by the function f(x) = - 27x³ - 135x² - 72x + 220, where x is the number of months passed since starting the website. The number of free movies available to choose from can be modeled as 3x + 11.

The expression that can be used to determine the average number of people that watch each free movie can be written as -

y = (- 27x³ - 135x² - 72x + 220)(3x + 11)

y = 3x(- 27x³ - 135x² - 72x + 220) + 11(- 27x³ - 135x² - 72x + 220)

y = - 81x⁴ - 405x³ - 216x² + 660x - 281x³ - 1485x² - 792x + 2420

Therefore, the expression that can be used to determine the average number of people that watch each free movie is -

y = - 81x⁴ - 405x³ - 216x² + 660x - 281x³ - 1485x² - 792x + 2420

Answer:

I do this program too, do you have any apps/websites that help with this program??

Step-by-step explanation:

Answer:

The equation that can be used to solve for m∠1 is:

m∠1 = One-half(a – b)

This is because angle 1 intercepts arc a, which has a measure of a. By the same token, angle 2 intercepts arc b, which has a measure of b. The sum of the measures of angles 1 and 2 is equal to the measure of the angle formed by the two intersecting chords, which is one-half the sum of the measures of arcs a and b. Therefore, we have:

m∠1 + m∠2 = One-half(a + b)

Since m∠2 is not given, we cannot solve for m∠1 using this equation. However, we can use the fact that the sum of the measures of the angles in a triangle is 180 degrees to get:

m∠1 + m∠2 + m∠3 = 180

where m∠3 is the measure of the angle formed by the two chords outside the circle. Since this angle is supplementary to angle 1, we have:

m∠1 + m∠3 = 180

Substituting the equation for the sum of the measures of angles 1 and 2, we get:

m∠1 + One-half(a + b) = 180

Solving for m∠1, we get:

m∠1 = 180 - One-half(a + b) = One-half(360 - a - b) = One-half(a - b)

Based on the calculations, option D, which is $5,000 at 2 percent interest compounded for four years, will result in the least amount of interest paid.

To determine which loan will result in the least amount of interest paid, we need to calculate the total interest for each option and compare them. Let's calculate the interest for each loan:

A. $10,000 at 2 percent interest compounded for four years:

To calculate the compound interest, we use the formula A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

For option A, the future value (A) can be calculated as:

A = 10,000(1 + 0.02/1)^(1*4) ≈ 10,816.65

The interest paid would be the difference between the future value and the principal:

Interest = 10,816.65 - 10,000 = 816.65

B. $10,000 at 2 percent simple interest for four years:

For simple interest, we use the formula I = P * r * t, where I is the interest, P is the principal amount, r is the interest rate, and t is the number of years.

For option B:

Interest = 10,000 * 0.02 * 4 = 800

C. $5,000 at 4 percent interest compounded for four years:

Using the compound interest formula:

A = 5,000(1 + 0.04/1)^(1*4) ≈ 5,897.77

Interest = 5,897.77 - 5,000 = 897.77

D. $5,000 at 2 percent interest compounded for four years:

Using the compound interest formula:

A = 5,000(1 + 0.02/1)^(1*4) ≈ 5,407.10

Interest = 5,407.10 - 5,000 = 407.10

Comparing the total interest paid for each option:

A: $816.65

B: $800

C: $897.77

D: $407.10

The best option which describes the p-value is 0.02 < p-value < 0.025.

We know that for the p-value method,

Z = (Sample Mean - Population Mean) / (standard deviation/sqrt (number of selections))

The average GPA for all the college students in the United States as of 2006 = 3.11 (Sample Mean)

The average GPA of randomly selected students at Texas A&M

= 3.27 (Population Mean)

Number of students randomly selected = 47

Standard deviation of them = 0.54

Therefore, Z = (3.27-3.11)/ (0.54/ sqrt(47)) = 2.031

Hence, by right tailed test,

p = 0.024

which implies, 0.02 < p-value < 0.025.

Surface area of figure = 200.52 meter²

Step-by-step explanation:

Given:

Side of square cut = 12 meter

Diameter of semi circle = 12 meter

Find:

Surface area of figure

Computation:

Diameter of semi circle = 12 meter

Radius of semi circle = Diameter of semi circle / 2

Radius of semi circle = 12 / 2

Radius of semi circle = 6 meter

Surface area of figure = Surface area of square + Surface of cylinder

Surface area of figure = [Side x Side] + πr²/2

Surface area of figure = [12 x 12] + (3.14)(6)²/2

Surface area of figure = [144] + (3.14)(36)/2

Surface area of figure = 144 + 56.52

Surface area of figure = 200.52 meter²

The last-minute cancellations of two families (11 people in total) due to illness may affect the decision as to which company offers more favorable terms, depending on the specific circumstances and fee structures of the companies involved.

If the rate is based on per person, canceling 11 people would significantly reduce the total cost for both companies. In this case, one would compare the changed prices of each company to determine which one offers the better deal.

However, with flat-rate pricing regardless of the number of participants, the cancellation of 11 people would not affect costs for either company. In such a scenario, the cancellation will not affect the evaluation of which company presents the better offer.

x² + 14x + 40 = ( x + 4 )( x + 10 )

main formula: x² + ( a + b )x + ab = ( x + a )( x + b )

A one-to-one correspondence between the set of all positive integers and the set of all rational numbers exists.

By definition, any rational number can be expressed as a fraction a/b, where a and b are integers and b is nonzero. Since any positive integer can be expressed as the fraction a/1, each positive integer can be associated with a rational number a/1.

Thus, there is a one-to-one correspondence between the set of all positive integers and the set of all rational numbers. Furthermore, since any rational number a/b can be expressed as the product of a and b, it can also be associated with the product of two positive integers a and b.

Thus, there is also a one-to-one correspondence between the set of all rational numbers and the set of all positive integers.

The remainder is 5 + c, which means that the expression P(x) = \(5x^4 + 7x^3 - 2x^2 - 3x + c\) divided by (x + 1) results in a quotient of\(5x^3 + 2x^2 - 4x + 4\) and a remainder of 5 + c.

To divide the polynomial P(x) = \(5x^4 + 7x^3 - 2x^2 - 3x + c\) by the binomial (x + 1), we can use polynomial long division.

Let's set up the long division:

    \(5x^3 + 2x^2 - 4x + 4\)

_______________________

x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)

We start by dividing the highest degree term of the dividend (5x^4) by the divisor (x + 1), which gives us 5x^3. We then multiply this quotient by the divisor (x + 1) and subtract it from the dividend:

              \(5x^3(x + 1)\)

     _______________________

x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)

- (\(5x^3 + 5x^2)\)

This leaves us with a new polynomial:\(2x^3 - 7x^2 - 3x + c\). We repeat the process by dividing the highest degree term of this polynomial (2x^3) by the divisor (x + 1), resulting in 2x^2. We then multiply this quotient by the divisor and subtract it from the polynomial:

              \(5x^3(x + 1) + 2x^2(x + 1)\)

     _______________________

x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)

-\((5x^3 + 5x^2)\)

_______________________

\(2x^2 - 3x + c\)

We continue this process until we reach the constant term, resulting in the remainder of the division.

At this point, we have:

               \(5x^3(x + 1) + 2x^2(x + 1)\)

     _______________________

x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)

Answer:

The probability is  \(  P( X \ge 2)  =  0.986 \)  

Step-by-step explanation:

From the question we are told that

     The proportion people with  Blood type AB-negative in the world  is p = 0.006

     The sample size is  n =  30

 Generally the distribution of people with  Blood type  AB-negative  follows a binomial distribution  

i.e  

         \(X  \~ \ \ \  B(n , p)\)

and the probability distribution function for binomial  distribution is  

      \(P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}\)

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

   Generally the probability that at least 2 of them have blood type AB-negative is mathematically represented as

         \( P( X \ge 2) = 1 - P( X <  2 ) \)

         \( P( X \ge 2) = 1 - [P( X = 0  ) + P( X = 1 ) ] \)

=>      \( P( X \ge 2) = 1 - [1  *  1  *  0.8348  ] + [30  *  0.006 *  0.83986 ] \)

=>     \(  P( X \ge 2)  =  0.986 \)

The probability that at least 2 students feel like they can do better in their math class is E. 0.9130.

To find the probability that at least 2 students feel like they can do better, we need to calculate P(X >= 2). This can be done using the cumulative distribution function (CDF) of the binomial distribution:

P(X >= 2) = 1 - P(X < 2) = 1 - P(X = 0) - P(X = 1)

Using the binomial probability formula, we can calculate:

P(X = 0) = (5 choose 0) * 0.6^0 * 0.4^5 = 0.01024

P(X = 1) = (5 choose 1) * 0.6^1 * 0.4^4 = 0.07680

Therefore,

P(X >= 2) = 1 - 0.01024 - 0.07680 = 0.91296

Rounding this to four decimal places, we get: 0.9130

Therefore, the answer is option E: 0.9130.
