Answer:
The correct answer is: domain: all real numbers, range: all real numbers greater than or equal to -5.
We can see that the function is a polynomial of degree 4, which means it is defined for all real numbers. Also, as x^4 is always non-negative, the minimum value of the function occurs when x=0, and it is f(0) = -4. Therefore, the range of the function is all real numbers greater than or equal to -4. However, since the function is increasing as we move away from 0, the range is actually all real numbers greater than or equal to the minimum value of -4 plus the vertical shift of -1, which is -5.

The correct answer is f(m)=5230(1.015)m12.
What is function?A function is a self-contained block of code that takes inputs, performs specific operations on those inputs, and produces an output. It is a subprogram that performs a specific task, and helps to break down larger programs into smaller, more manageable pieces. Functions are also reusable, meaning that once a function is written, it can be used over and over again in different places in the program.
This function can be used to represent the student enrollment m months after the study began, as it takes into consideration the number of years (t) represented by the number of months (m) and incorporates it into the equation. The equation multiplies the number of months (m) by 12 to convert it into the number of years (t) used in the original equation, f(t)=5230(1.015)t. This ensures that the correct student enrollment is calculated based on the number of months since the study began.

DIVIDING INTEGERS. Sarah and Anna both ran five laps of a race. When Anna finished, Sarah was 15 meters behind Anna suppose Sarah fell behind the same number of meters during each lap write an integer that describes how far is Sarah fell behind each lap
Sarah fell behind 3 meters each lap.
What is Total distance?
Whole distance refers to the actual travel distance between the origin and destination locations of the item.
If Sarah was 15 meters behind Anna when Anna finished the race, and they both ran the same distance, we can divide the total distance by the number of laps they ran to find the distance they ran per lap:
Total distance = 5 laps
Distance per lap = total distance / number of laps = 5 laps / 1 = 5
So Sarah and Anna each ran 5 meters per lap. If Sarah fell behind the same number of meters during each lap, we can use a negative integer to describe the distance she fell behind each lap. The distance she fell behind each lap is:
-3 meters (since 3 meters + 3 meters + 3 meters + 3 meters + 3 meters = 15 meters, which is the distance by which she was behind when Anna finished the race).
Therefore, Sarah fell behind 3 meters each lap.

Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes each day. He ran 2 miles around the football field before school and ran a longer route through his neighborhood after school. By the end of the week, Russell had run a total of 30 miles.
Using the arithmetic operations it is obtained that Russell ran 4 miles through his neighborhood every day after school.
To solve this problem, we can use the following equation -
total distance = distance per day x number of days
We know that Russell ran 2 miles around the football field before school every day.
Using multiplication,
Therefore, his total distance for the week from running around the football field is -
2 miles/day × 5 days = 10 miles
We also know that Russell ran a longer route through his neighborhood after school every day.
Let's call the distance of this route "x" miles.
Russell ran this route 5 times during the week, so his total distance from running through his neighborhood is -
Use multiplication,
x miles/day × 5 days = 5x miles
Finally, we know that Russell's total distance for the week was 30 miles. We can set up the equation -
Use addition,
10 miles + 5x miles = 30 miles
Simplifying, we get -
5x miles = 20 miles
x = 4 miles
Therefore, the distance value is obtained as 4 miles.

The probability of both independent events A and B happening together is P(A n B) = 0.1.
What is meant by probability?
An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur. In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.
Given,
Probability of A, P(A) = 0.2
Probability of B, P(B) = 0.4
P(A U B) = 0.5
We are asked to find P(A n B)
Now we know,
P(A U B) = P(A) + P(B) - P(A n B)
Then,
P(A n B) = P(A) + P(B) - P(A U B) = 0.2 + 0.4 - 0.5 = 0.1

What are a company's earnings?The gains that a company makes are its earnings. They are obtained by deducting revenue from cost of products sold, running costs, and taxes. The creation and ongoing running of a company are primarily motivated by the desire to generate profits. Dividend payments to stockholders can then be made with the earnings.
If the factory earned $80 per man-hour of labor when it opened, and each year earns an additional 5% per man-hour, we can calculate the earnings for any given year using the formula:
E = $80 × (1 + r)ⁿ
where E is the earnings per man-hour, r is the annual rate of increase (5% = 0.05), and n is the number of years since the factory opened.
For example, if we want to find the earnings per man-hour after 3 years, we would plug in n=3:
E = $80 × (1 + 0.05)³
E = $80 × 1.157625
E = $92.61
Therefore, after 3 years, the factory earns $92.61 per man-hour of labor.
Similarly, if we want to find the earnings per man-hour after 5 years, we would plug in n=5:
E = $80 × (1 + 0.05)⁵

The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.
What is surface area?Surface area is the total exposed area of a three-dimensional object, including the object's base area and lateral area. It is the area of the surface or outer boundary of an object and is measured in units squared such as square meters or square centimeters. Surface area is an important concept in mathematics, physics, and engineering, as it is used to calculate the amount of material needed to construct an object.
The total surface area of the building block can be found by adding the area of the six faces of the block together. To calculate the surface area of the block, we first need to find the area of each face. The six faces of the building block are four rectangular faces and two triangular faces. The area of each rectangular face can be found using the formula A=l×w, where l is the length and w is the width. The area of each triangular face can be found using the formula A=(b×h)/2, where b is the base and h is the height.
By adding the area of each face together, the total surface area of the building block can be found. The total surface area is equal to the sum of the four rectangular faces plus the two triangular faces. The total surface area of the building block is therefore (4×l×w) + (2×(b×h)/2), which is equal to (2×l×w) + bh.

Out of 187 randomly selected adults in the United States who were surveyed, 82 exercise on a regular basis. Construct a 90% confidence interval for the proportion of all adults in the United States who exercise on a regular basis. Round to three decimal places.
The true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493 with 90% confidence interval.
How to construct a confidence interval for the proportion?To construct a confidence interval for the proportion of all adults in the United States who exercise on a regular basis, we can use the formula:
CI = p ± z√(p(1-p)/n)
where:
p = proportion of the sample who exercise on a regular basis
n = sample size
z = z-score from the standard normal distribution corresponding to the desired level of confidence
Here, p = 82/187 = 0.4385 and n = 187.
A standard normal distribution table or calculator, or use the following formula:
z = invNorm((1 + C)/2)
where:
C = confidence level (expressed as a decimal)
invNorm() = inverse normal distribution function
For a 90% confidence level, C = 0.90, so:
z = invNorm((1 + 0.90)/2) = invNorm(0.95) ≈ 1.645
Substituting in the values, we get:
CI = 0.4385 ± 1.645√(0.4385(1-0.4385)/187) ≈ 0.384, 0.493
Therefore, we can say with 90% confidence that the true proportion of all adults in the United States who exercise on a regular basis is between 0.384 and 0.493, rounded to three decimal places.

11. Jenn bought 4 identical book
bags online for a total cost of
$95.65 including a flat ate of
$4.99 for shipping. Write an
equation to find the cost of each
book bag, b.
Answer:
Step-by-step explanation:
Let x be the cost of each book bag. Then, we can set up the following equation based on the information given:
4x + 4.99 = 95.65
Here, 4x represents the cost of the four identical book bags, and 4.99 is the flat rate for shipping. We add them up to get the total cost of $95.65.
To solve for x, we can first subtract 4.99 from both sides of the equation to isolate the term 4x on the left-hand side:
4x = 90.66
Then, we can divide both sides of the equation by 4 to solve for x:
x = 22.67
Therefore, each book bag costs $22.67.
2 glasses of milk and 3 snack bars have a total of 73 carbohydrates (carbs), and 4 glasses of milk and 2 snack bars have a total of 86 carb how many carbs are in 1 snack bar
In the given situation, one snack bar has 14 carbohydrates.
How to calculate the no. carbs in one snack bar?Let's denote the number of carbs in one snack bar as "x".
From the given information, we can set up a system of two equations:
2x + 3y = 73 (where y is the number of carbs in one glass of milk)
4x + 2y = 86
We can then solve for x by using elimination or substitution.
Using elimination, we can multiply the first equation by 2 and subtract it from the second equation:
4x + 2y = 86
(4x + 6y = 146) (2 times the first equation)
-4y = -60
Dividing both sides by -4, we get:
y = 15
Substituting this value of y into the first equation, we can solve for x:
2x + 3y = 73
2x + 3(15) = 73
2x + 45 = 73
2x = 28
x = 14
Therefore, there are 14 carbs in one snack bar.
Step-by-step explanation:
Let's start by defining some variables to represent the unknowns in the problem:
Let x be the number of carbohydrates in one snack bar.
Now, we can use the given information to set up a system of equations:
2x + 3y = 73 (where y is the number of carbohydrates in one glass of milk)
2y + 4x = 86
We have two equations and two unknowns, so we can solve for x and y using any method we prefer. Here, we will use the substitution method:
Rearrange the first equation to solve for y: y = (73 - 2x)/3
Substitute this expression for y in the second equation: 2((73 - 2x)/3) + 4x = 86
Simplify: (146 - 4x)/3 + 4x = 86
Multiply both sides by 3 to eliminate the fraction: 146 - 4x + 12x = 258
Simplify: 8x = 112
Solve for x: x = 14
Therefore, one snack bar has 14 carbohydrates.

Let's start by defining some variables to represent the unknowns in the problem:
Let x be the number of carbohydrates in one snack bar.
Now, we can use the given information to set up a system of equations:
2x + 3y = 73 (where y is the number of carbohydrates in one glass of milk)
2y + 4x = 86
We have two equations and two unknowns, so we can solve for x and y using any method we prefer. Here, we will use the substitution method:
Rearrange the first equation to solve for y: y = (73 - 2x)/3
Substitute this expression for y in the second equation: 2((73 - 2x)/3) + 4x = 86
Simplify: (146 - 4x)/3 + 4x = 86
Multiply both sides by 3 to eliminate the fraction: 146 - 4x + 12x = 258
Simplify: 8x = 112
Solve for x: x = 14
Therefore, one snack bar has 14 carbohydrates.

Answer:[tex]\frac{1}{8}[/tex]<[tex]\frac{3}{20}[/tex]
Step-by-step explanation:
In a certain weather forecast, the chances of a thunderstorm are stated as "4 in 19." Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive.
It’s not 0.210 or 0.21052632 ik you need to do 4 divided by 19
So, by resolving the given, we obtain the result: The probability value for probability this ranges from 0 to 1 inclusive.
What is probability?Calculating the chance that an event will occur or a statement will be true is the subject of probability theory, a branch of mathematics. A risk is a number between 0 and 1, where 1 denotes certainty and a probability of about 0 denotes the likelihood that an event will occur. The likelihood that an event will take place is mathematically expressed as probability. Probabilities can also be expressed as percentages ranging from 0% to 100% or as integers between 0 and 1. the proportion of equally plausible possibilities that actually happen in relation to all possible outcomes when a certain event occurs.
It is necessary to divide the number of desired outcomes by the total number of potential outcomes in order to describe the specified degree of possibility as a probability value between 0 and 1 inclusive.
When the likelihood of a thunderstorm is expressed as "4 in 19," it suggests that out of the 19 potential outcomes, 4 of them (a thunderstorm) are desirable (weather conditions).
Hence, the likelihood of a thunderstorm is represented as:
4/19
The probability value for this ranges from 0 to 1 inclusive.

A triangle has sides with lengths of 9 yards, 17 yards, and 18 yards. Is it a right triangle?
Answer:
No
Step-by-step explanation:
from Pythagoras theorem, if the triangle is right angled square of largest side should be equal to sum of the squares of smaller two sides. the square of largest side is 18^2= 324
9^2=81 and the last side is 17^2= 289
81+ 289= 370
This triangle is NOT a right triangle.

Solve for the variable
DUE TODAY PLEASE HELP!
Values of the variable are as follows:
V = 20
R = 28
X = 48
What are ratios?We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. The part to whole ratio is one, and the part-to-part ratio is another. The part-to-part ratio illustrates the relationship between two separate entities or groupings.
In the questions given,
The ratios of the sides of the first triangle = 36/18
= 2/1 or 2:1
Now in the second triangle, V/10 = 2/1
⇒ V = 20
In the second question in case of the squares,
the ratios of the sides = 13/13 = 1:1
So, the value of R = 28
Now in the last question,
The ratio of the rectangle's sides is 6:2. = 3/1 o 3:1
So, 144/X = 3/1
⇒ X = 144/3
= 48
