You have $50 on a giftcard, and buy Pokemon card packages that cost $10.50 each. Let y represent the amount left on the giftcard after purchasing x card packages.
Answers
Answer: The equation would be Y= 50- 10.50(x)
Step-by-step explanation: If you were to solve, it would be 50-10.50(4). I got the 4 because that is how many packs you can spend without going over $50. So, 10.50 x 4 = 42. So, now we subtract 42 from 5, so therefore we are left with 8. So we could write the equation like
- Y= 50-10.50(x)
Or
- 50-10.50(x) = y
So, plugging in the numbers we got, it would look like this
Y= 8
X= 4
So, it would be written like this:
8= 50 - 10.50(4)
8= 50- 42
Y=8.
I hope this helped!
The equation in which y represents the amount left on the gift card after purchasing x card packages is given by y = 50 - 10.50x
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Total amount that can be spent = $50.
Cost of one Pokemon card package = $10.50.
Also, y represents the amount left after purchasing x card packages.
Since, the price of one card package = $10.50
Price of x card packages = 10.50x
The equation for amount y left after purchasing x card packages
y = 50 - 10.50x
The required equation for amount left can be given as y = 50 - 10.50x.

A certain strain of bugs had a population of 72. Two weeks later the population had reduced to 28.a) Develop the function of the form p = ae^kt that represents the population after t weeks.b) Use the function to predict when the population will be less than 1 bug (i.e. disappear).
Answers
ANSWER:
(a)
\(p=72\cdot e^{-0.472t}\)(b)
During the 9th week, in week 10, the population has already disappeared
STEP-BY-STEP EXPLANATION:
We have that the function has the following form:
\(p=a\cdot e^{kt}\)(a)
We can calculate the value of k, knowing that after two weeks the population dropped from 72 to 28, therefore we replace these values and solve for k, like this:
\(\begin{gathered} 28=72\cdot e^{k\cdot2} \\ e^{2k}=\frac{28}{72} \\ 2k=\ln (\frac{28}{72}) \\ k=\frac{\ln(\frac{28}{72})}{2} \\ k=-0.472 \end{gathered}\)Therefore, the function would be:
\(p=72\cdot e^{-0.472t}\)(b)
In order to predict when the population is less than 1, we must do the following inequality:
\(\begin{gathered} 1<\: 72\cdot\: e^{-0.472t} \\ \frac{1}{72}\frac{1}{72} \\ -0.472t>\ln (\frac{1}{72}) \\ t<\frac{\ln (\frac{1}{72})}{-0.472} \\ t<9.05 \end{gathered}\)Which means that between the first 8 weeks the population will be greater than 1 and during the ninth week the population will begin to be less than 1

Three segments are chosen at random from six segments having lengths of 2, 3, 5, 6, 7 and 10 units. What is the probability that the three segments chosen could form a triangle? Express your answer as a common fraction
Answers
Using the probability concept, it is found that there is a \(\frac{7}{20}\) probability that the three segments chosen could form a triangle.
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, the order in which the sides of the segments are chosen is not important, hence, the combination formula is used to find the number of total outcomes.Combination formula:
\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by:
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
Total outcomes:
3 segments from a set of 6 lengths, hence:
\(C_{6,3} = \frac{6!}{3!3!} = 20\)
Desired outcomes:
Segments can make a triangle if the sum of the lengths of the smaller segments is greater than the length of the larger segment.Hence, the possible options are: (2,5,6), (3,5,6), (3,5,7), (5,6,7), (5,6,10), (5,7,10), (6,7,10).There are 7 desired outcome, hence \(D = 7\)Then:
\(p = \frac{D}{T} = \frac{7}{20}\)
\(\frac{7}{20}\) probability that the three segments chosen could form a triangle.

Therefore, the probability that the average weight of the sample of 39 Goliath Grouper is within 14 pounds of the average weight of all Goliath Grouper caught on the Treasure Coast is approximately 0.2342 or 23.42%.
What is mean?In mathematics and statistics, the mean is a measure of central tendency of a set of numerical data. It is also known as the arithmetic mean or average, and is calculated by summing up all the values in the dataset and then dividing by the number of values. The mean provides a useful summary of the data as it gives an idea of the typical or average value in the dataset. It is commonly used in various fields, including finance, science, and social sciences, to analyze and interpret data. However, the mean can be sensitive to extreme values or outliers in the dataset, so it is important to consider other measures of central tendency, such as the median and mode, in addition to the mean.
Here,
We can approach this problem using the central limit theorem, which states that the distribution of sample means will be approximately normal, with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
Let's first calculate the standard error of the mean:
standard error of the mean = standard deviation / sqrt(sample size)
= 74 / √(39)
≈ 11.83
Next, we need to find the z-score corresponding to a sample mean within 14 pounds of the population mean:
z = (sample mean - population mean) / standard error of the mean
= (418 - 14 - 418) / 11.83
= -1.19
Using a standard normal distribution table or calculator, we can find that the probability of a z-score less than -1.19 is about 0.1171. Since we're interested in the probability that the sample mean is within 14 pounds of the population mean, we can multiply this probability by 2 to account for the area under the curve in both tails:
P(sample mean within 14 pounds of population mean) ≈ 2 * 0.1171 ≈ 0.2342

The area of the composite figure whose vertices have the (2,-2), (2,1), (4,2), (6,2), (4,-1) coordinates is 6 square units
We first need to plot all the given points A (2,-2), B (2,1), C (4,2), D (6,2)and E (4,-1) which is coordinate geometry
After joining the Points which is a pentagon and it can be divided in two shapes one is triangle CDE and a quadrilateral ABCE
Using the distance formula
BC = \(\sqrt{(y2-y1)^{2}+(x2-x1)^{2} }\) = \(\sqrt{(2-1)^{2} + (4-2^{2} }\) = √5
Since BC = AE and BC ll AE , we can say ABCE is a parallelogram
area of a parallelogram = base × Altitude
= 2 × 2= 4
Area of triangle CDE where CD is perpendicular and CE is the base
= 1/2 ( 2×2)

= 2 square units
So the area of ABCDE = Area of ABCE + area of CDE

Determine the turning points and distinguish between them when necessary y=x³ - 3x - 9x + 4
Answers
The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).
To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.
1. Find the derivative of the function:
y' = 3x² - 6x - 9
2. Set the derivative equal to zero and solve for x:
3x² - 6x - 9 = 0
3. Factorize the quadratic equation:
3(x² - 2x - 3) = 0
4. Solve the quadratic equation by factoring or using the quadratic formula:
(x - 3)(x + 1) = 0
This gives us two possible values for x: x = 3 and x = -1.
5. Substitute these critical points back into the original function to find the corresponding y-values:
For x = 3:
y = (3)³ - 3(3)² - 9(3) + 4
= 27 - 27 - 27 + 4
= -23
For x = -1:
y = (-1)³ - 3(-1)² - 9(-1) + 4
= -1 - 3 + 9 + 4
= 9
6. Therefore, the turning points are (3, -23) and (-1, 9).
Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans
Answers
We know that he used 5/6 gallons of gas per hour of driving.
So, the total amount of gas he used is 5/6 * x.
We also know that he used a total of 5 3/4 gallons of gas.
So, we can set up the equation:
5/6 * x = 5 3/4
To solve for x, we can first convert 5 3/4 to an improper fraction:
5 3/4 = 23/4
Then, we can multiply both sides of the equation by the reciprocal of 5/6:
x = (5 3/4) / (5/6)
x = (23/4) / (5/6)
x = (23/4) * (6/5)
x = 27.6/4
x = 6.9
Therefore, Pablo was driving for a total of 6.9 hours.

On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve?
Answers
6 tables are required. Each prime number attender should serve 3 customers each.
The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
All the numbers other than prime numbers are composite numbers.
The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.
Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables
Therefore, 6 tables are required.
Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.
Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.
Thus, each prime number attender should serve 3 customers each.
