Ilya goes to the store with $1.40 in his pocket and $1.85 in his wallet. Which model shows how much money Ilya has all together?
Answers
The model is a linear function that shows $3.25 money that Ilya has all together
What is meant by a linear function?The phrase linear function relates to two distinct but related concepts in mathematics:
Some authors use the term "linear function" only for linear mappings that accept values in the scalar field; these are more frequently known as linear forms.
Calculus' "linear functions" qualify as "linear mappings" when (and only when) f(0,..., 0) = 0, or, equivalently, when the aforementioned constant b equals zero.
A linear function in calculus and related fields is one whose graph is a straight line, that is, a polynomial function of degree zero or one. The word affine function is commonly used to distinguish such a linear function from the other idea.
A linear function is also known as a linear map in linear algebra, mathematical analysis, and functional analysis.
Given,
Ilya goes to the store with $1.40 in his pocket and $1.85 in his wallet.
Total money=$1.40+$1.85
=$3.25
The model is a linear function that shows $3.25 money that Ilya has all together.

Answers
The conclusion "(x)(A(x) ∨ B(x))" is false since there exist elements (e.g., 1) that satisfy B(x) but not A(x).
To show that the argument is invalid using the model universe method, we need to find a counterexample where the premises are true, but the conclusion is false.
Let's consider the following interpretation:
Domain of discourse: {1, 2}
A(x): x is even
B(x): x is odd
Under this interpretation, the premises "(x)(A(x) ∧ B(x))" and "(∃x)A(x)" are true because all elements in the domain satisfy A(x) ∧ B(x), and there exists at least one element (e.g., 2) that satisfies A(x).
However, the conclusion "(x)(A(x) ∨ B(x))" is false since there exist elements (e.g., 1) that satisfy B(x) but not A(x).
In this counterexample, the premises are true, but the conclusion is false, demonstrating that the argument is invalid using the model universe method.

Mrs. Martin deposits $2,300 into a savings account. Her account earns an interest rate of 1.5%. How much money will she have in the account after 18 months?
Answers
Assuming that the account earns the interest as simple interest, to calculate the amount Mrs. Martin will have after 18 months, you have to use the following formula:
\(A=P(1+rt)\)Where
A is the accrued amount
P is the principal amount
r is the interest rate expressed as a decimal number
t is the time expressed as years
She deposited $2300, this is the principal amount.
The interest rate of the account is 1.5%, to express it as a decimal value you have to divide it by 100
\(r=\frac{1.5}{100}=0.015\)To express the time in "years" you have to divide the given months by 12
\(t=\frac{18}{12}=1.5\)Now that all values are expressed in their corresponding units, you can calculate the final balance in her account as:
\(\begin{gathered} A=2300(1+(0.015\cdot1.5)) \\ A=2300\cdot1.0225 \\ A=2351.75 \end{gathered}\)After 18 months she will have $2351.75 in her account.

Answer:
y = 21
Step-by-step explanation:
According to the Side Splitter Theorem, if a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.
Therefore, according to the Side Splitter Theorem:
\(\boxed{\sf AD : DB = AH : HC}\)
From inspection of the given triangle, the lengths of the line segments are:
AD = 3DB = 7AH = 9HC = yTo find the value of y, substitute the given line segment lengths into the proportion and solve for y:
\(\begin{aligned}\sf AD : DB &=\sf AH : HC\\\\3:7&=9:y\\\\\dfrac{3}{7}&=\dfrac{9}{y}\\\\3 \cdot y&=9 \cdot 7\\\\3y&=63\\\\\dfrac{3y}{3}&=\dfrac{63}{3}\\\\y&=21\end{aligned}\)

Answers
A and B have the same elements, the measure of AUB will be equal to the measure of B.
To show that if m*(A) = 0, then m*(AUB) = m*(B), we need to prove the following:
1. If m*(A) = 0, then A is a null set.
2. If A is a null set, then AUB = B.
3. If AUB = B, then m*(AUB) = m*(B).
Let's break down each step:
1. If m*(A) = 0, then A is a null set:
- By definition, a null set has a measure of 0.
- Since m*(A) = 0, it implies that A has no elements or its measure is 0.
- Therefore, A is a null set.
2. If A is a null set, then AUB = B:
- Since A is a null set, it means that it has no elements or its measure is 0.
- In set theory, the union of a null set (A) with any set (B) results in B.
- Therefore, AUB = B.
3. If AUB = B, then m*(AUB) = m*(B):
- Since AUB = B, it implies that both sets have the same elements.
- The measure of a set is defined as the sum of the measures of its individual elements.
- Since A and B have the same elements, the measure of AUB will be equal to the measure of B.
- Therefore, m*(AUB) = m*(B).
By proving these three steps, we have shown that if m*(A) = 0, then m*(AUB) = m*(B).

Answers
The probability that a randomly selected month's number of order is more than 150 is 0.13%
Given, shawn finds that the monthly number of take-out orders at a restaurant is normally distributed with mean 132 and standard deviation 6.
⇒ mean = 132
⇒ standard deviation = 6
Analysis:
Set the monthly number of take out order as x.
From the question, we know:
P(x > 150) = P(x-132/ > 150-132/6)
= P(x=132/6 > 3)
= 1 - P(x-132/6 ≤ 3)

Answers
The value of x in the domain of f(x) is x = 10.option (A)
To find the domain of the function f(x) = √(x - 8), we need to consider the values of x for which the expression under the square root is non-negative.
That is, x - 8 ≥ 0
Simplifying, we get x ≥ 8
Therefore, any value of x that is greater than or equal to 8 is in the domain of the function.

If you were constructing a 99% confidence interval of the population mean based on a sample of n=30 where the standard deviation of the sample S=0.05, the critical value of t will be 2.7564 2.4922 2.7969
Answers
The critical value of t for constructing a 99% confidence interval with a sample size of 30 and a sample standard deviation of 0.05 is 2.7564.
A confidence interval is a range of values within which the population parameter is estimated to lie with a certain level of confidence. In this case, we are constructing a 99% confidence interval for the population mean. The critical value of t is used to determine the width of the confidence interval.
The formula for calculating the confidence interval for the population mean is:
Confidence interval = sample mean ± (critical value) * (standard deviation of the sample / square root of the sample size)
Given that the sample size is 30 (n = 30) and the standard deviation of the sample is 0.05 (S = 0.05), we need to find the critical value of t for a 99% confidence level. The critical value of t depends on the desired confidence level and the degrees of freedom, which is equal to n - 1 in this case (30 - 1 = 29). Looking up the critical value in a t-table or using statistical software, we find that the critical value of t for a 99% confidence level with 29 degrees of freedom is approximately 2.7564.
Therefore, the 99% confidence interval for the population mean would be calculated as follows: sample mean ± (2.7564) * (0.05 / √30). The final result would be a range of values within which we can be 99% confident that the true population mean lies.

Slope (m) = -2/1 or -2
Since the second point’s x-coordinate is zero, that means its y-coordinate is the y-intercept.
Y-intercept (b) = -3.5
Slope-intercept equation: y = mx + b

the minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is 384.12, which can be rounded up to 385.
The minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is as follows:
95% confidence, within 5 percentage points, and a previous estimate of 0.25.
The formula to calculate the sample size required for the study to determine the proportion is given by:
`n = Z²pq / E²`
Where n = sample size
Z = z-value (1.96 at 95% confidence interval)
E = margin of error
p = estimated proportion of the population
q = 1 - pp
q = estimated proportion of population without the condition (1 - 0.25 = 0.75)
Given,
Z = 1.96E = 0.05p = 0.25q = 0.75
Substituting these values in the above formula, we get;
`n = (1.96)²(0.25)(0.75) / (0.05)²``n = 384.16`
Therefore, the minimum number of subjects needed for a research study regarding the proportion of respondents who reported a history of diabetes using the following criteria is 384.12, which can be rounded up to 385.
