Answer:
A = $100(1.12)^2
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For this case;
P = $100
t = 2years
n = 1
r = 12% = 0.12
Substituting the values, we have;
A = $100(1+0.12)^(2)
A = $100(1.12)^2

What is the volume of air in the beach ball that has a 12 inch diameter
To find the volume of air in a beach ball with a 12-inch diameter, one must calculate the volume of a sphere using the formula V = 4/3 π r^3, with the radius being half the diameter, resulting in approximately 904.78 cubic inches.
Explanation:The question you're asking pertains to the calculation of the volume of a sphere, as the beach ball is essentially a spherical object. When you have a diameter, the radius (which is half of the diameter) is necessary for the volume calculation. The formula for the volume of a sphere is given by V = 4/3 π r^3, where V is the volume, π (pi) is approximately 3.14159, and r is the radius of the sphere.
First, we convert the diameter into the radius by dividing by 2: 12 inches / 2 = 6 inches. Then, we use the formula to calculate the volume: V = 4/3 π • (6 inches)^3.
Therefore, the volume is: V = 4/3 π • 216 inches^3. After calculating this, we find that the volume of air inside the beach ball is approximately 904.78 cubic inches, assuming no other factors are affecting the volume, such as the thickness of the ball's material.

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?
A.
12
B.
14
C.
15
D.
27
Answer:D.27
They already won 12 games (80% of 15%) and need or win 15 more.
Check: 15+12 =27 =90%
30 30
Answer:
C
Step-by-step explanation:
First, find out how many games they won:
x/15 = 80/100
Cross multiply
x × 100 = 15 × 80
100x = 1200
x = 12
They won 12 out of 15 games
Second, find out how many wins out of 30 games are needed to have a 90% winning percentage
x/30 = 90/100
Cross multiply
x × 100 = 30 × 90
100x = 2700
x = 27
27 game wins are needed to have a 90% winning percentage
Lastly, find the difference between 27 wins (total needed) and 12 wins (total number of wins they currently have)
27 - 12 = 15
They need to win 15 more games to have a 90% winning percentage

Given the sequence:
25, 21, 17, 13,...
Write the explicit equation that models the sequence.
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

Whenever Nicole rents a movie from iTunes, the probability that it will be a comedy is 52%. Of the next seven movies she rents, what is the probability that she rents NO MORE THAN two comedies?
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.
Explanation: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.
Explanation: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.
P(X = 0) = (7 choose 0) * 0.52^0 * 0.48^7P(X = 1) = (7 choose 1) * 0.52^1 * 0.48^6P(X = 2) = (7 choose 2) * 0.52^2 * 0.48^5Summing these probabilities will give us the final probability that Nicole rents no more than two comedies.

A cat is stuck on the roof If the ladder is 16 feet long and must be placed six feet long and must be placed six feet away from the building How high can the ladder reach up the building to help save the cat?
14.8 feet
22 feet
37.9 feet
220 feet
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.

Help? I can't seem to understand arithmegic sequence.
A sequence [tex]\{a_n\}[/tex] is arithmetic if the difference between consecutive terms is some fixed number, regardless of which pair of consecutive terms you pick out of the sequence.
For example, the following sequences are arithmetic:
1, 2, 3, 4, 5, 6, ... (difference = 1)
-25, -20, -15, -10, -5, ... (difference = 5)
2. Carla's sequence is not arithmetic, because the differences between consecutive terms are all different:
13 - 11 = 2
17 - 13 = 4
25 - 17 = 8
She can adjust the sequence by changing the last two numbers to 15 and 17, since this makes the difference fixed:
13 - 11 = 2
15 - 13 = 2
17 - 15 = 2
and so on.
3. The sequence
45, 48, 51, 54, ...
is arithmetic with difference 3 between terms. Recursively, we can write the [tex]n[/tex]th term, [tex]a_n[/tex], in terms of the previous, [tex](n-1)[/tex]th term, [tex]a_{n-1}[/tex]:
[tex]a_n=a_{n-1}+3[/tex]
By this definition, we can just as easily write the [tex](n-1)[/tex]th term in terms of the [tex](n-2)[/tex]th term:
[tex]a_{n-1}=a_{n-2}+3[/tex]
Then, substituting this into the previous equation, we have
[tex]a_n=(a_{n-2}+3)+3=a_{n-2}+2\cdot3[/tex]
We can continue this process to write [tex]a_n[/tex] in terms of [tex]a_1[/tex]:
[tex]a_{n-2}=a_{n-3}+3\implies a_n=a_{n-3}+3\cdot3[/tex]
[tex]a_{n-3}=a_{n-4}+3\implies a_n=a_{n-4}+4\cdot3[/tex]
and so on. (You might notice that the subscript of the term on the right side, and the number of 3s being added, together sum to [tex]n[/tex].) The pattern continues down to
[tex]a_n=a_1+(n-1)\cdot3[/tex]
The first term in this sequence is [tex]a_1=45[/tex], so we have
a. [tex]a_n=45+3(n-1)=42+3n[/tex]
where [tex]n=1,2,3,\ldots[/tex].
b. You can fill in the blanks by just adding 3 to the previous term:
45, 48, 51, 54, 57, 60, 63, 66, 69, ...
Then, using the formula found in (a), the 15th term of the sequence is
[tex]a_{15}=42+3\cdot15=87[/tex]

Jose and Maris work for different car dealerships. Jose earns a monthly salary of $3,500 plus a 6% commission on his sales, x. Maris earns a
monthly salary of $4,000 plus a 4% commission on her sales, x. For what value of sales, x, will Jose's earnings be greater than Maris' earnings?
Choose the inequality that could be used to solve this problem.
3,500 + 0.06x > 4,000 + 0.04x
3,500 + 0.6x > 4,000 + 0.4x
3,500 + 6x > 4,000 + 4x
3,500 + 0.06x < 4,000 + 0.04x
Answer:
(A)3,500 + 0.06x > 4,000 + 0.04x
Step-by-step explanation:
Jose's Earnings
Monthly Salary = $3,500
6% commission on his sales, x =0.06x
Total = 3500+0.06x
Maris' Earnings
Monthly Salary = $4,000
4% commission on her sales, x =0.04x
Total = 4000+0.04x
If Jose's earnings be greater than Maris' earnings, then:
3500+0.06x > 4000+0.04x

Your consulting firm is submitting a bid for a big contract. From previous data, you know your firm has a 51% of successfully landing the contract. The agency to which you submitted your bid has asked for more information about your bid. Past experience indicates that for 70% of successful bids and 44% of unsuccessful bids, the agency asks for more information. (In other words, if you successfully bid, then the probability the agency asks for information is 70%, etc.) If an agency asks for more information, what is the probability the bid is successful
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
Alanna tried to solve an equation step by step.
4c=12
4c/=12.4
c=48
Find Alanna's mistake.
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.
