exercise 5.3.1. recall from exercise 4.4.9 that a function f : a → r is lipschitz on a if there exists an m > 0 such that ∣∣∣∣ f(x) − f(y) x − y ∣∣∣∣ ≤ m for all x ?
If f is differentiable on a closed interval [a,b] and if f' is continuous on the interval [a,b], Then f is Lipschitz on [a,b].
What is a Lipschitz function?
If a neighborhood U of x exists for any x in X such that f restricted to U is Lipschitz continuous, then the function is said to be locally Lipschitz continuous. Alternatively, f is locally Lipschitz if and only if it is Lipschitz continuous on each compact subset of X if X is a locally compact metric space.
Now,
Assume that f can be differentiated and that f' is continuous on [a,b]. Therefore, f' is bounded since [a,b] is compact. In other words, for all x [a,b] there exists M > 0 such that: |f'(x)| ≤ M.The Mean Value Theorem therefore ensures that there exists c between x and y such that: [tex]|\frac{f(x)-f(y)}{x-y}|=|f'(c)|\leq M[/tex], for each x,y ∈[a,b].Given that x and y were chosen at random, we can infer that f is Lipschitz on [a,b] since the inequality: [tex]|\frac{f(x)-f(y)}{x-y}|\leq M[/tex], holds for all x,y ∈ [a,b].Hence, If f is differentiable on a closed interval [a,b] and if f' is continuous on the interval [a,b], Then f is Lipschitz on [a,b].

The price of a shirt is marked down from $12.59 to $10.00 what percent is decrease of the shirt
The percentage by which the price of the shirt is decreased is 20%.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100. The abbreviation "pct.", "pct," and sometimes "pc" is also used. A percentage is a dimensionless number with no unit of measurement.So, the price of a shirt is marked down from $12.50 to $10.00.
Previous price = $12.50New price = $10.00Then,
Change in price = Previous price - New price= $12.50 - $10.00= $2.50Now, the shirt's percentage has decreased:
(Change in price)/(Previous price) ×100
Therefore, the percentage by which the price of the shirt is decreased is 20%.

When part of an original figure matches up with part of a copy. These could be segments points or angles.
When a portion of an original figure corresponds to a portion of a duplicate, we refer to them as corresponding parts. This could be in the form of points, segments, angles, or distances.
What exactly do we mean by "corresponding parts"?Parts that match between two congruent triangles are said to as matching. You can identify the corresponding angles and sides.
How many congruent components are there?Triangles are congruent when all 3 types of corresponding sides are congruent. Two triangles have three sides that are equivalent.
How do you determine which sections of a congruent triangle are corresponding?The equals sign with a squiggly line on top indicates that the items on each side of the equation were congruent. Then, identify the corresponding sides. Corresponding sides are sides that match between two triangles. Congruent triangles will have the same length.

a researcher may claim a causal relationship between variables if one variable influences another. please select the best answer from the choices provided t f
The claim that a researcher may infer a causal link between variables if one effects another is False.
What do you mean when you say that variables have casual relationships?If a change in one variable's level results in a change in the other variable, then there is a causal relationship between the two variables. Keep in mind that correlation does not always imply causation. Two variables may be linked together without one of them directly contributing to the other's observable behavior.
For instance,
the chart below illustrates the relationship between ice cream sales and temperature. Any business can utilize the concept of causality. As is clear from the graph, there is a correlation between warmer weather and increased sales.
A casual relationship between two variables only exists when one of the variables actually causes the other to exist, which does not appear to be the case here. Instead, since a change in one variable affects the other, this scenario can be thought of as a correlated relationship.

A truck can be rented from Company A for $130 a day plus $0.30 per mile. Company B charges $70 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Considering the definition of an equation and the way to solve it, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.
The members of an equation are each of the expressions that appear on both sides of the equal sign.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Number of miles in this caseFirst, you define the variable "m" as the number of miles rented from a truck to a company in a day. You know that:
A truck can be rented from Company A for $130 a day plus $0.30 per mile. Company B charges $70 a day plus $0.60 per mile to rent the same truck.So the price of each company is:
Price of company A=130 + 0.30mPrice of company B=70 + 0.60mIf the rental costs for Company A and Company B are the same, the equation in this case is:
Price of company A= Price of company B
130 + 0.30m= 70 + 0.60m
Solving:
130 - 70= 0.60m - 0.30m
60= 0.30m
60÷0.30= m
200= m
In summary, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

A binomial experiment has 4 trials in which p = 0.35. What is the probability of 1 success?
The formula for calculating the probability of one success under certain conditions is:
x=0.4.
What is probability?"The ratio of the number of favorable outcomes to the total number of outcomes is the standard mathematical definition of probability. Probability is never more than one, and it is never equal to that number."
Generally, the equation for Probability is mathematically given as

It is given that:
Suppose the cost in dollars of producing x model kits is given by the polynomial 500,000 + 2x and the revenue generated from sales is given by the polynomial 30x - 0.00005 x².
The profit = revenue - cost
The profit = (30x - 0.00005 x²) - (500,000 + 2x)
The profit = 30x - 0.00005 x² - 500,000 - 2x
The profit = 28x - 500,000 - 0.00005 x²
Plug x = 300,000 in the profit expression.
The profit = 3400000

The total proportion of shirts between two prices is 0.9431, which is obtained using the knowledge of proportion and statistics.
What is proportion?
In mathematics, a proportion is defined as the comparison between two numerical quantities. If both possess the same nature, they are called directly proportional, or else called inversely proportional.
Calculation of the proportion based on the problem
The mean and standard deviation are given to be 45 and 5 respectively
Calculate standard normal variate using the formula, z = (x - 45) / 5
Taking x = 37, we get,
z1 = (37 - 45) / 5
= -1.6
Using the z table, we get the value, z1 = 0.0548
Now, taking x = 59.35, we get,
z2 = (59.35 - 45) / 5
= 2.87
Using the z table, we get the value, z2 = 0.9979
The proportion between two prices is given by z = z2 - z1
z = 0.9979 - 0.0548
= 0.9431
Hence, the proportion of shirts between the two prices is 0.9431.
