Part 1: The function c (m) = 60 + 10m gives the monthly cost "C" of visiting a gym as a
function of the number of visits "m."
What would the inverse function tell us?
O The minimum number of visitis
O The visits for a cost of $60
O The cost in terms of visits "m"
O The number of visits made for a costs of "C"
Option (4): The inverse of the function tells us the number of visits m that can be made for a cost of c.
What is meant by the inverse of a function?
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.
A function that can reverse into another function is known as an inverse function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as " f ⁻¹ " or " F ⁻¹."
Given a function,
c(m) = 60 + 10m
where c = cost of visiting the gym
m = number of visits
Then the Inverse function is:
c(m) - 60 = 10m
m = (c(m) - 60) / 10
Therefore the inverse of the function tells us the number of visits m that can be made for a cost of c.

Yes, that is correct; If the sky is clear, we are able to see the stars at night.
A star is a celestial body that maintains its shape thanks to its own gravity. Also, a star has the ability to generate its own light, an example of a star is the Sun.
The stars are always there, but during the day, the brightness of the sun makes it impossible for us to see them. However, at night when the sun is no longer visible, the stars become visible to us. This is why we can see the stars in the sky at night when there are no clouds obstructing our view.

5) The senior classes at High School A and High School B planned separate trips to New York City.
The senior class at High School A rented and filled 5 vans and 4 buses with 205 students. High
School B rented and filled 5 vans and 13 buses with 475 students. Each van and each bus carried
the same number of students. How many students can a van carry? How many students can a
bus carry?
The number of students the van carry is 17
the number of students the bus carry is 30
How to find the number of students can a bus carryLet's assume that a van can carry "v" students and a bus can carry "b" students.
From the information given, we can set up two equations:
5 vans + 4 buses = 205 students
5 vans + 13 buses = 475 students
We can write these equations as
5v + 4b = 205
5v + 13b = 475

You want to estimate the mean SAT score for a population of students with a 80% confidence interval. Assume that the population standard deviation is s = 120. If you want the margin of error to be approximately 10, you will need a sample size of_____
The sample size for the given data is 17
What is sample size?The sample size is a term used in market research for defining the number of subjects included in a sample size.
Given that, a sample size has an 80% confidence interval, the population standard deviation is s = 120, the margin of error to be approximately 10, We need to find the sample size,
Sample size = (z-score)²×SD×(1-SD) / (confidence interval)²

What does the size of stiffness matrix depend on?
the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.
In structural mechanics and engineering, the stiffness matrix is a mathematical representation of the stiffness of a structure, which relates the forces and displacements of the structure. The size of the stiffness matrix depends on several factors, including the number of degrees of freedom and the type of elements used in the analysis. The number of degrees of freedom (DOF) in the system determines the size of the stiffness matrix. DOF refers to the number of independent displacements or rotations that a structure can undergo in response to external forces. For example, a simple beam structure might have two DOF (vertical displacement and rotation), while a more complex structure such as a truss or frame might have many more DOF. The size of the stiffness matrix also depends on the type of elements used in the analysis. Different types of elements have different degrees of freedom and stiffness properties, which affect the size and shape of the stiffness matrix. For example, a truss element has two DOF and a constant axial stiffness, while a beam element has four or six DOF and variable stiffness properties that depend on its geometry and material properties.
In summary, the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.

The answer is: 1 part sample, 9 parts diluent, 1 part of the first dilution, 9 parts diluent, 1 part of the second dilution, 9 parts diluent
When creating a serial dilution, the starting concentration is typically given as a ratio of sample to diluent. For example, a 1/10 dilution would mean that there is one part of sample and nine parts of diluent.
Now when we create a serial dilution from 1/10 to 1/1000, the first dilution will be 1 part sample and 9 parts diluent. The second dilution will be one part of the first dilution and nine parts diluent. The final dilution will be one part of the second dilution and nine parts diluent.
