over [a, b] then Let [a, b] and [c, d] be intervals satisfying [c, d] C [a,b]. Show that if f ∈ R over f ∈ R [c, d].
Answers
Since [c,d] is a subset of [a,b], and f is defined over the closed interval [a,b], it follows that f is also defined over the closed interval [c,d].Since f is defined over the closed interval [a,b], it must be bounded on this interval.
Thus, there exist constants M and m such that m ≤ f(x) ≤ M for all x ∈ [a,b].Similarly, since [c,d] is a subset of [a,b], the interval [c,d] is a closed subset of [a,b].
This means that the function f is bounded on [c,d] as well, since it is bounded on [a,b].Therefore, f ∈ R[c,d].
Thus, we have shown that if f ∈ R[a,b], then f ∈ R[c,d].

What is the unit rate for each size of peanut butter?
Regular: $ ____ per ounce
Family Size: $ _____ per ounce.
Which one is a better buy (claim)?
How do you know (reasoning)?
Answers
Answer:
It would be better to buy the regular size
Step-by-step explanation:
For regular size You would divide
16/3.36 = 4.7619
For family size you would divide
40/7.60 = 5.2631
As you can see with the regular size you would pay about $4.75 cents for every ounce but if you buy the family size then you would be paying about $5.26 for every ounce
Why is the property of closure important in math?
Answers
Understanding a set’s nature or properties is made easier by its closure property
What is the Closure Property?The set is closed if it has the closure property. This means that any operation performed on an element within a set will provide a result that belongs to that element’s set.
Why Closure Property is important?
Understanding a set’s nature or properties is made easier by its closure property. Mathematical applications of closure are numerous. Any operation that adheres to this condition is said to be “closed” or to have “fulfilled the operation’s closure property.”
Example – The set of even number is closed under subtraction
Even – Even = Even

if v in r3 and v·v = 0, then v is the zero vector. is it true or false? explain your answer.
Answers
It is true that if v in r3 and v·v = 0, then v is the zero vector.
If v is a vector in R3 (three-dimensional real space) and v·v = 0, then v is the zero vector.
The dot product of a vector with itself, v·v, is equal to the square of the magnitude of the vector, ||v||^2. If v·v = 0, it follows that ||v||^2 = 0, which means that the magnitude of v is 0. In other words, v has a length of 0.
The only vector in R3 with a length of 0 is the zero vector, which is represented by the vector (0, 0, 0). Thus, if v·v = 0, v must be the zero vector.

The difference between 2 numbers is 8. The sum of the two numbers is 20. Find the number.
Answers
Answer:
The numbers are 6 and 14
Step-by-step explanation:
Let the two numbers be x and y
x-y = 8
x+y = 20
Add the two equations
x-y = 8
x+y = 20
-----------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Subtract the two equations
x-y = 8
-x-y = -20
-----------------
-2y = -12
Divide by -2
-2y/-2 = -12/-2
y = 6
The numbers are 6 and 14
Answer:
14, 6
Step-by-step explanation:
x-y =8 =>x=y+8

Maggie paddles her kayak 1/2 mile to an island. Then she paddles 4/5 miles to a beach. How far does Maggie paddle her kayak in all?
Answers
Answer:
\(\frac{13}{10} \:\:\:miles\)
Step-by-step explanation:
Maggie paddles her kayak \(\frac{1}{2}\) mile to an island.
Then she paddles \(\frac{4}{5}\) miles to a beach.
Now we have to find the total miles she travels.
Let us find now.
For that, you have to add two distances together.
\(\frac{1}{2} +\frac{4}{5}\)
\(\frac{1*5}{2*5} +\frac{4*2}{5*2}\)
\(\frac{5}{10} +\frac{8}{10}\)
\(\frac{13}{10} \:\:\:miles\)
Hope this helps you :-)
Answer:
1.3 miles total
Step-by-step explanation:
(1/2) + (4/5) miles total
Convert each fraction so that both denominators are the same:
(1/2) = (5/10)
(4/5) = (8/10)
---
Add:
(5/10) + (8/10) = (13/10) miles
Maggie paddled a total of (13/10) miles, which we could reduce and also say 1.3 miles total.
What is the measure of asymmetry?
Answers
The measure of asymmetry, also known as skewness, is a statistical measure that describes the degree of asymmetry in a distribution of data.
It provides information on the shape of the distribution and the deviation of the data from a normal distribution. In a symmetrical distribution, the mean, median, and mode are all equal, and the distribution is said to have zero skewness. A distribution that is skewed to the right, or positively skewed, has a tail that extends to the right, and the mean is larger than the median. A distribution that is skewed to the left, or negatively skewed, has a tail that extends to the left, and the mean is smaller than the median.
Skewness is calculated by taking the third standardized moment of the distribution, which is the average cubed deviation from the mean, and dividing it by the cube of the standard deviation. This gives a measure of the degree of asymmetry of the distribution.
Skewness is an important measure in many fields, including finance, economics, and biology, as it can indicate whether a distribution is likely to produce extreme values, and can help identify outliers in the data. It is also important in hypothesis testing, as many tests assume that the data are normally distributed, and skewed data can affect the validity of the results.

Answers
Therefore, the year with the highest level of income equality is 1976, when the Gini coefficient was .43.
What is Gini Coefficient?The Gini coefficient is a measure of income inequality in a population, named after the Italian statistician Corrado Gini. It is a statistical measure that ranges from 0 to 1, where 0 represents perfect equality (everyone has the same income) and 1 represents perfect inequality (one person has all the income). The Gini coefficient is calculated by dividing the area between the Lorenz curve and the line of perfect equality by the total area below the line of perfect equality. The Lorenz curve is a graphical representation of the distribution of income or wealth in a population, where the horizontal axis represents the percentage of the population, and the vertical axis represents the cumulative percentage of the income or wealth.
Here,
The Gini coefficient is a measure of income inequality, with values ranging from 0 to 1. A Gini coefficient of 0 indicates perfect equality, where everyone has the same income, while a coefficient of 1 indicates perfect inequality, where one person has all the income. In this case, the highest level of income equality would be the year with the lowest Gini coefficient.

Line 1: (0,-4) and (2,2)
Line 2:(0,-4) and (4,5)
We have to find which line has a steeper slope.
First we will find the slope of each line.
We know that slope of a line with points (a,b) and (c,d) is given by:-
(d-b)/(c-a)
Slope of Line 1:
(2-(-4))/(2-0) = 6/2 = 3
Slope of Line 2:
(5-(-4))/(4-0) = 9/4 = 9/4 = 2.25
We know that greater the slope of the line means greater the steep of the line.
As,
3 > 2.25
Hence, Line 1 is steeper than Line 2.
