show that after choosing a basis the vector space of linear functions l(v,w) from v to w is isomorphic to m mn where m
A linear transformation L: V→W is called an isomorphism if it is a bijection. Two vector spaces are called isomorphic if there is an isomorphism mapping one of the spaces onto the other.
Often two vector spaces can consist of quite different types of vectors but, on closer examination, turn out to be the same underlying space displayed in different symbols. For example, consider the spaces
R² = {(a, b) | a, b ∈ R} and P₁= {a+bx|a,b ∈ R}
Compare the addition and scalar multiplication in these spaces:
(a,b) + (a₁,b₁) = (a+a₁, b+b₁) (a+bx) + (a₁+b₁x) = (a+a₁) + (b+b₁)x
r(a,b) = (ra,rb) r(a+bx)=(ra)+(rb)x

ap exam a small class of five statistics students received the following scores on their ap exam: 5, 4, 4, 3, 1. a) calculate the mean and standard deviation of these five scores.
The mean of the score is 3.4 and the standard deviation is 3.2.
Scores of students = 5, 4, 4, 3 and 1
When determining the mean of a group of numbers, add up all the numbers and divide by the total number in the group.
Calculating the mean -
= Sum of total values / Total values
= 5 + 4 + 4 + 3 + 1 / 5
= 17/5
= 3.4
By averaging the squared deviations of each integer from the mean, you may get the variance before calculating the standard deviation.
Calculating the Standard deviation -
σ = √ ∑ (xi - u)²/n
σ² = (1² + (3.4 - 1)² + (3.4 - 4)² + (3.4 - 4)²+ (3.4 - 5)²) / 5

By the age of 21, the best violinists and pianists will have practiced at least 10,000 hours. If you practice an instrument 45 minutes, 0.75 hour, a day for 365.25 days, the length of a year, how many hours will you have practiced?
Answer:
Step-by-step explanation:
if you practice an instrument for 45 minutes or 0.75 hrs per day
The violinist's Age is 21 years
The total number of hours practiced per year is 0.75 hours /day * 365days/year
If you want to reach 10,000 hours by the age of 21, you would need to practice for approximately:
10000 hours / 21 years = 476 hours per year
So, you would need to practice for approximately 476 hours/year for 21 years to reach 10,000 hours of practice.

Square ABCD and equilateral triangle AED are coplanar and share AD, as shown. what is the measure, in degrees, of angle BAE?
The measure of angle BAE is equal to the sum of the measures of angles ABC and ACD, or 120°.
Since ABCD and AED are both plane figures and share AD, the measure of angle BAE must be equal to the measure of angle BCD. Angle BCD is the exterior angle of triangle ABC, so the measure of angle BCD is equal to the sum of the measures of angles ABC and ACD. Therefore, the measure of angle BAE can be calculated using the formula:
m∠BAE=m∠ABC+m∠ACD
Since triangle AED is equilateral, all three angles are equal to 60°. Therefore, the measure of angles ABC and ACD are both equal to 60°. Therefore, the measure of angle BAE is equal to the sum of the measures of angles ABC and ACD, or 120°.

which has the benefit of being cheaper and easier to conduct than conducting a study of an entire population. however, this method leaves room for possible error because you're not observing every member of the student body (the population). ultimately, the goal of inferential statistics is to use sample statistics to make inferences about population parameters.
This method uses a sample of the population mean to make generalizations about the whole, but can introduce error due to not observing the whole population.
The goal of inferential statistics is to use sample statistics to make inferences about population parameters. This is done by taking a sample of the population, usually a relatively small one, and using it to draw conclusions about the entire population. This method has the benefit of being much cheaper and easier to conduct than studying an entire population, however, it leaves room for error because it does not observe every member of the population. If the sample is not representative of the population, it can lead to faulty conclusions about the population as a whole. Additionally, if the sample size is too small, it may not be able to accurately represent the population. Therefore, it is important to carefully consider the sample size, as well as the representativeness of the sample, in order to draw reliable conclusions from inferential statistics.

when using the some rule ,we only use two of the equal ratios at one time.That is we work with pairs of _____ sides and angle?
When applying the some rule, we only combine two equal ratios at once. Consequently, we deal with pairs of sides and angles that have equivalent ratios.
Which set of ratios form a proportion?When two ratios are equal, a percentage is formed; alternatively, two equal ratios can be said to produce a proportion. When we understand that two ratios are equal, you can write a proportion. The ratios of these two numbers are equal.
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant. Two angles are said to be complimentary if their sum is 90 degrees. Alternatively put, two angles are said to be complimentary if they combine to make a right angle.

What is independent and dependent variable mean?One whose value is dependent on another variable is said to be a dependent variable. Its quantity depends on the other, as the name would imply. Dependent variables are subject to external influences and do not change independently.
Independent variables don't rely on other factors, as opposed to dependent variables. Their individualistic values are what changed the dependent variables, and this is what caused the change. Independent variables are, once more, unaffected by external factors, as their name implies.
Because the money she earn id depended on the number of hour she work,

You are given the following information about N, the annual number of claims for a randomly selected insured:
P(N=0) = 1/2
P(N=1) = 1/3
P(N>1) = 1/6
Let S denote the total annual claim amount for an insured. When N=1, S is exponentially distributed with mean 5. When N>1, S is exponentially distributed with mean 8. Determine P(4
When N=1, P(S=4) = 1 - exp^(-4/5). When N>1, P(S=4) = 1 - exp^(-4/8). Therefore, P(S=4) = 1/2 * (1 - exp^(-4/5)) + 1/6 * (1 - exp^(-4/8)). S denote the total amount for an insured.
When N=1, the total annual claim amount for an insured, S, is exponentially distributed with mean 5. This means that the probability of S being equal to 4 is 1 - exp^(-4/5). When N>1, the probability of S being equal to 4 is 1 - exp^(-4/8). Since P(N=0) = 1/2 and P(N=1) = 1/3, the total probability of S being equal to 4 is the sum of the probabilities for N=1 and N>1.

A picture of a bottle is 1/8 of its actual size.
The height of the bottle is 3 cm in the picture.
What is the actual height of the bottle?
Answer:
the actual size is 24 cm
Step-by-step explanation:
first, the problem tells us that the picture is only 1/8th of the original. the easiest way to find this is by thinking about the fact that we only have 1 out of 8 parts. each of these parts are going to be the exact same size.
each of the 8 parts is going to equal 3cm. so multiply 3 cm by your 8 parts.
3*8=24

which of the following values are examples of a boolean data type? select all that apply.
A Boolean data type is a type of data that can have one of two possible values, either true or false.
Boolean values are used in logic and programming to make decisions and determine the flow of a program. In programming, Boolean values are typically represented with 0 for false and 1 for true. Examples of Boolean values include the following:
• (5 > 4) True
• (10 = 10) True
• (3 < 2) False
• (17 ≥ 17) True
• (“dog” = “cat”) False
• (“hello” ≠ “goodbye”) True
Boolean values are used in programming to perform calculations, make decisions, and control the flow of a program. For example, an if statement is a type of decision making statement that uses a Boolean expression to determine if a certain condition is true or false. If the condition is true, the program will execute the specified code, and if false, the program will skip the specified code. Boolean values are also used to perform calculations, such as in the AND, OR, and NOT logical operators, which are used to combine two or more conditions into one expression. For example, the AND operator would return true if both of the conditions are true and false if either of the conditions are false.
