16x² + 24xy + 9y² can be represented as a perfect trinomial.

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomials are classified based on degree as linear, quadratic, cubic and so on. A trinomial is a polynomial with three terms.

A perfect square trinomial is a trinomial that can be obtained from a binomial equation.

16x² + 24xy + 9y² = 16x² + 8xy + 18xy + 9y²

= 8x(2x + y) + 9y(2x + y)

= (8x + 9y)(2x + y)

16x² + 24xy + 9y² can be represented as a perfect trinomial.

Answer:

Volume, [tex]V=96.79\ \text{feet}^3[/tex]

Step-by-step explanation:

An artist creates a cone shaped sculpture for an art exhibit.

Height of sculpture is 8 feets

The circumference of base of the cone is 21.352 feet.

The base of a con is circular shaped. So,

[tex]2\pi r= 21.352[/tex]

r is radius of cone

[tex]r= \dfrac{21.352}{2\times 3.14} \\\\r=3.4\ ft[/tex]

The volume of cone shaped sculpture is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (3.4)^2 \times 8\\\\V=96.79\ \text{feet}^3[/tex]

So, the volume of the sculpture is [tex]96.79\ \text{feet}^3[/tex].

Answer:

The explicit equation that models the sequence is [tex]f(n)=25-4(n-1)[/tex].

Step-by-step explanation:

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference.

In general, this is the standard explicit formula of an arithmetic sequence whose first term is A and common difference is B:

                                                 [tex]f(n)=A+B(n-1)[/tex]

The sequence {25, 21, 17, 13, ...} is an example of an arithmetic sequence the same number, -4, is subtracted to each term to get to the next term.

We know the first term is 25 and common difference is -4.

Applying the standard explicit formula of an arithmetic sequence we get that

[tex]f(n)=25-4(n-1)[/tex].

The explicit equation is aₙ = 29 - 4n

25, 21, 17, 13...….

The sequence follows an arithmetic sequence. Therefore,

common difference (d) = 21 - 25 = -4

first term(a) = 25

Therefore, the explicit equation can be represented below:

aₙ = a + (n - 1)d

aₙ = 25 + (n - 1)-4

aₙ = 25 - 4n + 4

aₙ = 29 - 4n

Answer:

step 1

Step-by-step explanation:

Alanna divided one side of the equation by 4 but multiplied the other side by 444. Alanna should have divided both sides of the equation by 4 to isolate c.

Alanna's mistake was dividing the equation by 12.4 instead of dividing both sides by 4.

Alanna made a mistake in the second step of solving the equation. The correct step should be as follows:

Step 1: 4c = 12

Step 2: Divide both sides by 4, not 4.4: (4c) / 4 = 12 / 4

Step 3: c = 3

So, the correct solution is c = 3, not c = 48 as Alanna calculated.

Alanna's mistake in solving the equation 4c = 12 occurred during the second step of the process. When attempting to isolate the variable "c," she divided both sides of the equation by 4, but her error lies in the value she used for this division. Instead of correctly dividing by 4, she mistakenly divided by 4.4.

The correct approach in this situation is to perform the same mathematical operation on both sides of the equation to maintain its balance. Dividing both sides by 4 allows us to isolate "c" and find its value. When we divide 12 by 4, we get 3, which is the correct solution to the equation.

In contrast, Alanna's incorrect division by 4.4 led her to the erroneous result of c = 48. This error likely arose from a simple calculation mistake. It's crucial to pay attention to each step of solving equations to avoid such errors, as they can significantly affect the final solution and lead to incorrect conclusions.

In summary, Alanna's mistake was dividing both sides of the equation by 4.4 instead of 4, resulting in the incorrect solution c = 48, when the correct solution is c = 3.

Answer: 412.310 miles

Step-by-step explanation:

The diagram representing the scenario is shown in the attached photo. The bearing is taken with respect to the northern direction. The angles at B are determined by applying the concept of alternate angles with respect to parallel lines.

A right angle triangle ABC is formed. The starting point is A and the end point is C. The distance, x between A and C represents the hypotenuse of the triangle.

We would determine x by applying Pythagoras theorem which us expressed as

Hypotenuse² = opposite side² + adjacent side²

x² = 400² + 100² = 170000

x = √170000

x = 412.310 miles

Answer:

a) [tex] P(X>10) =1-P(X<10) = 1-F(10) = 1-\frac{10-6}{12-6} = 0.333[/tex]

b) [tex] P(X<11)= F(11) = \frac{11-6}{12-6}= 0.833[/tex]

c) [tex] P(6.5<X<8)= F(8) -F(6.5) = \frac{8-6}{12-6}-\frac{6.5-6}{12-6}= 0.333-0.0833 = 0.250[/tex]

In the figure attached we have the illustration for the probability for each part.

Step-by-step explanation:

For this case we define the random variable X as the voltages in a circuit  and the distribution for X is given by:

[tex]X \sim Unif (a= 6, b=12) [/tex]

Part a

we want this probability:

[tex] P(X>10)[/tex]

We can use the cumulative distirbution function given by:

[tex] F(x) = \frac{x-a}{b-a}, a\leq X \leq b[/tex]

And using the complement rule we have this:

[tex] P(X>10) =1-P(X<10) = 1-F(10) = 1-\frac{10-6}{12-6} = 0.333[/tex]

Part b

We want this probability:

[tex] P(X<11)[/tex]

And using the cumulative distirbution function we got:

[tex] P(X<11)= F(11) = \frac{11-6}{12-6}= 0.833[/tex]

Part c

We want this probability:

[tex] P(6.5<X<8)[/tex]

And using the cumulative distirbution function we got:

[tex] P(6.5<X<8)= F(8) -F(6.5) = \frac{8-6}{12-6}-\frac{6.5-6}{12-6}= 0.333-0.0833 = 0.250[/tex]

In the figure attached we have the illustration for the probability for each part.

To find the probability of a given range of voltage levels in a circuit, we need to determine the proportion of voltages that fall within that range. In this case, the range of voltages varies between 6 volts and 12 volts, and they are spread evenly. The probability of the voltage being greater than 10 volts is 1/3, the probability of the voltage being less than 11 volts is 5/6, and the probability of the voltage being between 6.5 volts and 8 volts is 1/4.

To find the probability of a given range of voltage levels, we need to determine the percentage of voltage values that fall within that range. In this case, the range of voltages varies between 6 volts and 12 volts. Since the voltages are spread evenly, we can calculate the probability by finding the proportion of the range compared to the total range of possibilities.

Answer:

P(S/A) = 0.6235

Step-by-step explanation:

Let's call S that you successfully bid, S' that you unsuccessfully bid, A that the agency asked for more information and A' that the agency didn't asked for more information.

So, the probability P(S/A) that the bid is successful given that the agency asks for more information is calculated as:

P(S/A) = P(S∩A)/P(A)

Where P(A) = P(S∩A) + P(S'∩A)

Then, the probability P(S∩A)  that you successfully bid and the agency asked for more information is:

P(S∩A) = 0.51 * 0.7 =  0.357

Because your firm has a 51% of successfully landing the contract and if you successfully bid, then the probability the agency asks for information is 70%.

At the same way, the the probability P(S'∩A)  that you unsuccessfully bid and the agency asked for more information is:

P(S'∩A) = (1-0.51) * 0.44 = 0.2156

So, P(A) and P(S/A) are equal to:

P(A) = 0.357 + 0.2156 = 0.5726

P(S/A) = 0.357/0.5726 = 0.6235

How did it get on the roof?

Answer:

The answer is A. 14.8 feet.

Explanation:

We can use the Pythagorean theorem to solve this problem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the ladder represents the hypotenuse, and the distance from the building and the height reached by the ladder represent the other two sides.

Let's denote:

- [tex]\( a \)[/tex] as the distance from the building to the base of the ladder (6 feet)

- [tex]\( b \)[/tex] as the height reached by the ladder up the building (what we need to find)

- [tex]\( c \)[/tex] as the length of the ladder (16 feet)

According to the Pythagorean theorem, we have:

[tex]\[ a^2 + b^2 = c^2 \][/tex]

Substituting the given values:

[tex]\[ 6^2 + b^2 = 16^2 \][/tex]

[tex]\[ 36 + b^2 = 256 \][/tex]

[tex]\[ b^2 = 256 - 36 \][/tex]

[tex]\[ b^2 = 220 \][/tex]

To find [tex]\( b \)[/tex], we take the square root of both sides:

[tex]\[ b = \sqrt{220} \][/tex]

Using a calculator, we find:

[tex]\[ b \approx 14.8 \][/tex]

So, the ladder can reach up to approximately 14.8 feet on the building to help save the cat.

The question pertains to cumulative probability in a binomial distribution, where the probability of Nicole renting no more than two comedies out of seven movies is calculated by adding the probabilities of renting 0, 1, or 2 comedy movies.

The question is about calculating a cumulative probability, specifically the probability that Nicole rents no more than two comedy movies out of seven. Here the events are not mutually exclusive, and we use the concept of binomial distribution to solve it.

The binomial distribution describes the probability of having exactly k successes (defined as the desired outcome, in our case renting a comedy) in n independent Bernoulli trials (independent events with two possible outcomes - here, renting a comedy or not).

To calculate the binomial distribution, we would use the formula P(k; n, p) = C(n, k) * (p^k) * (1-p)^(n-k), where P(k; n, p) is the probability of k successes in n trials, C(n, k) is the combinations of n items taken k at a time, and p is the probability of a success on a single trial.

In this case, we want to find the cumulative probability, i.e., the probability that Nicole rents 0, 1, or 2 comedy movies. This can be calculated as P(0;7,0.52) + P(1;7,0.52) + P(2;7,0.52).

C(n, k) can be calculated using the formula n! / [(n-k)!k!], where n is the total number of trials and k is the number of successes and '!' denotes factorial.

To determine the probability that Nicole rents no more than two comedies out of seven movies, we apply the binomial probability formula to calculate the cumulative probability of renting 0, 1, or 2 comedies, and summing those probabilities gives the final answer.

The problem at hand requires calculating the probability of an event occurring a certain number of times given a fixed probability. In this case, we are interested in finding the probability that Nicole rents no more than two comedies out of the next seven movies from iTunes, with the probability of renting a comedy being 52%.

To solve this, we can use the binomial probability formula, which is P(X = k) = (n choose k) * p^k * (1-p)^(n-k), where 'n' is the number of trials, 'k' is the number of successes, and 'p' is the probability of success on any given trial. We are looking for P(X ≤ 2), which is the cumulative probability of renting 0, 1, or 2 comedies.

Summing these probabilities will give us the final probability that Nicole rents no more than two comedies.
