Step-by-step explanation:
Laura has two jobs to help pay for her weekly expenses.
• Laura can work at most 20 hours per week.
She needs to earn at least $120.
• Laura's dog-walking job pays $9.00 per hour.
• Laura washing cars pays $11.00 per hour.
Create the system of inequalities to model Laura's situation where x represents the hours she spends dog-walking
and y represents the hours she spends washing cars.
Answer:
x*$9.00 + y*$11.00 ≥ $120
x + y ≤ 20 hrs
Step-by-step explanation:
we have the variables:
x = hours she spends dog-walking
y = hours she spends washing cars.
We know that she wins $9.00 per hour of dog-waling, and she wins $11.00 per hour of washing cars, then the total amount of money she wins per hour is:
x*$9.00 + y*$11.00
And she needs to earn at least $120, then we have the inequality:
x*$9.00 + y*$11.00 ≥ $120
And we also know that she can work, at most, 20 hours per week, then:
x + y ≤ 20 hrs
Then the system of inequalities that represents this situation is:
x*$9.00 + y*$11.00 ≥ $120
x + y ≤ 20 hrs
in an election debate, two candidates for governor are debating about whether to raise the general sales tax from 5 to 7 percent. candidate a argues that this would increase tax revenues, enabling the state to maintain essential services. candidate b argues that the tax would hurt retailers and consumers, slowing down the economy so much that it would decrease tax revenues too. what assumptions must the candidates be making in order to justify their position?
In order to justify their position candidate make assumption that the price effect would be larger than the quantity effect.
What is Price?
The amount of money required to obtain a certain thing is referred to as its price. Price is a measure of value in the sense that the amount people are willing to pay for a commodity signifies its value.
Concept:
Candidate A claims that raising the sales tax from 5% to 7% will enhance revenue. This suggests that the price effect is greater than the quantity effect because when taxes rise, prices rise and quantities fall; hence, tax revenue will rise only if the price effect is more than the quantity effect.
And Candidate B claims that the tax would harm merchants and customers, slow the economy, and reduce tax revenue, but only if the quantity effect outweighed the price effect.
As a result, Candidate A believes that the price effect will be greater than the quantity effect.

We know that the square root of a number can be either positive or negative, but while defining the square root function, we restrict its range to be the set of all positive real numbers and hence making all square roots possible to be positive.
If the range for the square root of a number is set to be positive as well as negative it wont be a function that is why there is a restriction to the range of this set allowing only positive real numbers.

Q2: Use Euler's method to approximate y' = y - x for the initial condition y(0) = 1.5,0 ≤x≤ 1.5,h=0.5 with accuracy e=0.0001
The value of given differential equation \(y' = y - x\) with the initial condition \(y(0) = 1.5\), on the interval \(0 \leq x \leq 1.5\), is \(y(1.5) = y_4 = 5.4296875\).
The differential equation we are given is \(y' = y - x\), with the initial condition \(y(0) = 1.5\). We are asked to approximate the solution on the interval \(0 \leq x \leq 1.5\) with a step size of \(h = 0.5\), and we want to achieve an accuracy of \(e = 0.0001\).
We start by calculating the first two values, \(y_0\) and \(y_1\), using the formula:
\(y_1 = y_0 + h \cdot f(x_0, y_0)\)
Here, \(h\) represents the step size, \(f(x, y)\) represents the derivative \(y'\) in terms of \(x\) and \(y\), and \((x_0, y_0)\) is the initial condition.
Using the given values, we can calculate \(y_1\) as:
\(y_1 = 1.5 + 0.5 \cdot (1.5 - 0) = 2.25\)
Next, we calculate \(y_2\) using the same formula:
\(y_2 = y_1 + h \cdot f(x_1, y_1)\)
Substituting the values \(x_1 = 0.5\) and \(y_1 = 2.25\), we get:
\(y_2 = 2.25 + 0.5 \cdot (2.25 - 0.5) = 3.375\)
Similarly, we can calculate \(y_3\) and \(y_4\) as:
\(y_3 = 3.375 + 0.5 \cdot (3.375 - 1) = 4.3125\)
\(y_4 = 4.3125 + 0.5 \cdot (4.3125 - 1.5) = 5.4296875\)
So, the value of \(y\) at \(x = 1.5\) is \(y(1.5) = y_4 = 5.4296875\).
Using Euler's method with a step size of \(h = 0.5\) and an accuracy of \(e = 0.0001\), the solution to the given differential equation \(y' = y - x\) with the initial condition \(y(0) = 1.5\), on the interval \(0 \leq x \leq 1.5\), is \(y(1.5) = y_4 = 5.4296875\).

A random variable is normally distributed with a mean of ? = 50 and a standard deviation of ? = 5.
a. What is the probability the random variable will assume a value between 45 and 55 (to 4 decimals)?
b. What is the probability the random variable will assume a value between 40 and 60 (to 4 decimals)?
a. There is a 0.6827 percent chance that the random variable will take on a value between 45 and 55. b. There is a 0.9545 percent chance that the random variable will take on a value between 40 and 60.
a. To find the probability that the random variable will assume a value between 45 and 55, we need to calculate the z-scores for each value and then use a standard normal distribution table or calculator.
The z-score for 45 is:
\(z = (45 - 50) / 5 = -1\)
The z-score for 55 is:
\(z = (55 - 50) / 5 = 1\)
Using a standard normal distribution table or calculator, we find the probability of the random variable assuming a value between 45 and 55 is:
P(-1 < Z < 1) = 0.6827 (to 4 decimals)
As a result, there is a 0.6827 percent chance that the random variable will take a value between 45 and 55.
b. To find the probability that the random variable will assume a value between 40 and 60, we again need to calculate the z-scores for each value and then use a standard normal distribution table or calculator.
The z-score for 40 is:
\(z = (40 - 50) / 5 = -2\)
The z-score for 60 is:
\(z = (60 - 50) / 5 = 2\)
Using a standard normal distribution table or calculator, we find the probability of the random variable assuming a value between 40 and 60 is:
P(-2 < Z < 2) = 0.9545 (to 4 decimals)
Hence, there is a 0.9545 percent chance that the random variable will take on a value between 40 and 60.

The addition table for Z10, also known as the integers modulo 10, is as follows:The multiplication table for Z10 is as follows:
In Z10, the elements that have multiplicative inverses are 1, 3, 7, and 9. This means that for each of these numbers, there exists another number that, when multiplied together, equals 1 modulo 10. For example, the multiplicative inverse of 3 is 7 because 3 * 7 ≡ 1 (mod 10).
An example in Z10 where ab = ac but b ≠ c is a = 2, b = 5, and c = 0. In this case, 2 * 5 ≡ 2 * 0 (mod 10) because both equal 0 (mod 10). This example is related to the existence of multiplicative inverses because it shows that not all elements in Z10 have multiplicative inverses. However, in this example, b ≠ c, indicating that 2 does not have a multiplicative inverse in Z10.

The largest number of participants at the concert was 4.
To determine the largest number of participants at the concert, we need to find the least common multiple (LCM) of 1050, 1575, and 3150. The LCM is the smallest positive integer that is a multiple of all three numbers.
The prime factorization of 1050 is 2 * 3 * 5 * 5 * 7.
The prime factorization of 1575 is 3 * 5 * 5 * 11.
The prime factorization of 3150 is 2 * 3 * 5 * 5 * 7 * 11.
The LCM of 1050, 1575, and 3150 is therefore 2 * 3 * 5 * 5 * 7 * 11 = 31500.
Since each participant received one of each item, the largest number of participants at the concert was
31500 / (1050 + 1575 + 3150) = 31500 / 7775 = 4.

class does not have a sister?
Has a brother Does not have a brother
Has a sister

Answer:
Step-by-step explanation:
First we need to calculate how many total students there are. Once we have the total we have to divide the number in the category that we want by the total number of students to calculate the probability of randomly getting a student in that category.
Total Students = 3 + 12 + 2 + 7 = 24 students
Probabilities:
does not have a sister = \(\frac{2 + 7}{24}\) = 0.375 or 37.5% (multiply decimal by 100 to get percentage.
Has a brother = \(\frac{3 + 2}{24}\) = 0.208 or 20.8%
Does not have a brother = \(\frac{12 + 7}{24}\) = 0.7916 or 79.2%
Has a sister = \(\frac{3 + 12}{24}\) = 0.625 or 62.5%
For any positive integer n, let An denote the surface area of the unit ball in Rn, and let Vn denote the volume of the unit ball in Rn. Let i be the positive integer such that Ai>Ak for all k k not equal to i. Similarly let j be the positive integer such that Vj>Vk for all k not equal to j. Find j−i.
To find the value of j - i, we need to determine the relationship between the surface areas (An) and volumes (Vn) of the unit ball in Rn for different positive integers n.
For the unit ball in Rn, the formula for surface area (An) and volume (Vn) are given by:
An = (2 * π^(n/2)) / Γ(n/2)
Vn = (π^(n/2)) / Γ((n/2) + 1)
where Γ denotes the gamma function.
To find the value of j - i, we need to identify the positive integers i and j such that Ai > Ak for all k not equal to i, and Vj > Vk for all k not equal to j.
First, let's analyze the relationship between An and Vn. By comparing the formulas, we can see that:
An / Vn = [(2 * π^(n/2)) / Γ(n/2)] / [(π^(n/2)) / Γ((n/2) + 1)]
= 2 / [n * (n-1)]
From this equation, we can deduce that An / Vn > 1 if and only if 2 > n * (n-1).
To find the positive integer i, we need to identify the highest positive integer n for which 2 > n * (n-1) holds true. We can observe that this condition is satisfied for n = 2. Therefore, i = 2.
Now, let's find the positive integer j. We need to identify the lowest positive integer n for which 2 > n * (n-1) does not hold true. We can observe that this condition is no longer satisfied for n = 3. Therefore, j = 3.
Finally, we can calculate j - i as follows:
j - i = 3 - 2 = 1
Therefore, j - i equals 1.
