Solve f (9) for f(x) = 2x+3
Answers
The value of the function for f(3) is 9.
Given that, a function, f(x) = 2x+3, we need to find the value of function for f(3).
So, for the same, put x = 3, in the function,
f(3) = 2(3) + 3
f(3) = 6+3
f(3) = 9
Hence the value of the function for f(3) is 9.

The only statements that is false is A. I only: 1. We use one-sample procedures when our samples are equal in size but aren't independent.
A one-sample procedure is used when we want to compare a sample mean to a known population mean or when we want to estimate a population mean using a sample mean. In a one-sample procedure, the sample is selected independently and is typically assumed to be random. So, independence of the sample is a requirement for one-sample procedure.

A gymnast joined a yoga studio to improve his flexibility and balance. He pays a monthly fee and a fee per class he attends. The equation y = 30 + 10x represents the amount the gymnast pays for his membership to the yoga studio per month for a certain number of classes.
Which graph represents this situation?
Answers
For the above case, the graph of the linear equation y = 20 + 10x
Which graph represents this situation?Each solution inside the scenario involving two variables may be thought of as the Cartesian coordinates of a specific point on the Euclidean plane.The answers to a linear equation create a line inside the Euclidean plane, and each line may be considered as the sum of all solutions to a linear model with two variables.
This is how this type of equation became known as “linear.” The solutions to an equation system with integer variables form a hyperplane in Euclidean space with size n (a subdomain of dimension n1).
Because linear equations typically properly reflect nonlinear systems, they are widely employed in all fields.
Mathematics as well as in physics and engineering.
Here the equation is given as y = 20 + 10x
Therefore at x = 0 , y = 20 and at y = 0, x = -2
This represents that the fixed monthly fee is 20 and the daily fee is 10.

a.y=2x-31
Answers
Answer:
y = (-1/2)x + 21/2
Step-by-step explanation:
Given equation:
y - 2x + 7
Coordinates = (5,8)
Find:
Perpendicular equation
Computation:
y = mx + c
y - 2x + 7
y = 2x - 7
So,
m = 2
The negative reciprocal of 2 is -1/2
So,
For,
Coordinates = (5,8)
y = mx + c
8 = (-1/2)(5) + c
8 = -5/2 + c
c = 8 + 5/2
c = 21 /2
So,
y = mx + c
y = (-1/2)x + 21/2

The value of x in the chord intersection is 16 units.
How to find the length of chord?The intersecting chord theorem states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.
Therefore, lets find the value of x in the intersecting chords as follows:
15 × x = 24 × 10
15x = 240
divide both sides of the equation by 15
x = 240 / 15
x = 16
Therefore,
x = 16 units

Answers
Eye color in this study is a categorical variable, and the corresponding trustworthiness rating is a numerical variable.
Categorical variable: "Eye color" is a categorical variable because it represents discrete categories or groups of individuals based on their eye color, such as blue, brown, green, etc. Categorical variables are qualitative variables that do not have numerical values and are typically used to represent characteristics or attributes of individuals or objects.
Numerical variable: "Trustworthiness rating" is a numerical variable because it represents a quantitative value assigned to individuals based on their trustworthiness. Numerical variables are quantitative variables that have numerical values and can be measured on a continuous or discrete scale, allowing for mathematical calculations and statistical analysis. In this case, the trustworthiness rating is a numerical variable that represents a quantitative measure of trustworthiness.

Deciding whether to issue a loan to an applicant based on demographic and financial data (with reference to a database of similar data on prior customers):
This task would likely be framed as a supervised learning problem. The goal is to predict whether to approve or reject a loan application based on the given data. Hence, it can be considered a classification problem.
In an online bookstore, making recommendations to customers concerning additional items to buy based on the buying patterns in prior transactions:
This task would also be framed as a supervised learning problem. The goal is to recommend additional items to customers based on their buying patterns. It can be approached as a recommendation system using collaborative filtering techniques, which involve predicting customer preferences. This can be considered a classification problem.
Identifying segments of similar customers:
This task would typically be framed as an unsupervised learning problem. The objective is to identify groups or clusters of similar customers based on their attributes or behaviors. Unsupervised learning algorithms such as clustering can be used to accomplish this task.
Estimating the repair time required for an aircraft based on a trouble ticket:
This task would likely be framed as a regression problem since the goal is to estimate the repair time, which is a continuous variable. Supervised learning techniques such as regression algorithms can be employed to predict the repair time based on the provided input features.

Step-by-step explanation:
Given:
Diameter of a cake = 12 cm
Area of one slice = 4π cm²
Find:
Total number of slices
Computation:
Radius of cake = 12 / 2 = 6 cm
Area of circle = πr²
Area of circle = π(6)²
Area of circle = 36π cm²
Total number of slices = Area of circle / Area of one slice
Total number of slices = 36π / 4π
Total number of slices = 9 slices

Money in a savings account is compounded continuously over time, t, and is modeled by the function f(t)=1000e0.047t. what is the rate at which the balance grows?
Answers
Compounded continuously the balance grows at a continuous rate of 1.7%.
What is compound interest ?
Compound interest is when you earn interest on both the money you've saved and the interest you earn. So let's say you invest $1,000 (your principal) and it earns 5 percent (interest rate or earnings) once a year (the compounding frequency).The model used for continuous compounding is
f(t) = Pe^(rt)
where P is the principal amount, and r is the interest rate being compounded. Assuming a typo in your given equation, you have
f(t) = 1000·e^(0.017t)
Matching the various parts of the equation, we see that P = 1000 and r = 0.017 = 1.7%.
Therefore, the balance grows at a continuous rate of 1.7%.
