4. Let f be a function with domain R. We say that f is periodic if there exists a p > 0 such that ∀x € R, f(x) = f(r+p).
(a) Prove that if f is continuous on R and periodic, then f has a maximum on R.
(b) Is part (a) still true if we remove the hypothesis that f is continuous? If so, prove it. If not, give a counterexample with explanation
Suppose f is continuous on R and periodic with period p. Since f is continuous on a closed interval [0,p], by the extreme value theorem, f attains a maximum and a minimum on [0,p]. Let M be the maximum of f on [0,p].
Then, for any x in R, we have f(x) = f(x + np) for some integer n. Let x' be the unique number in [0,p] such that x = x' + np for some integer n and 0 ≤ x' < p. Then, we have f(x) = f(x' + np) ≤ M, since M is the maximum of f on [0,p]. Therefore, f attains its maximum on R.
(b) Part (a) is not true if we remove the hypothesis that f is continuous. For example, let f(x) = 1 if x is rational and f(x) = 0 if x is irrational. Then, f is periodic with period 1, but f does not have a maximum or a minimum on R. To see why, note that for any x in R, there exists a sequence of rational numbers that converges to x and a sequence of irrational numbers that converges to x. Therefore, f(x) cannot be equal to any constant value.

Sum of biased dice. Let S be the sum of numbers obtained by rolling two biased dice with possibly different biases described by probabilities pi...ps, and ri.....76, all assumed to be nonzero.
The expected value of the sum of two biased dice can be calculated using the formula:
E(S) = ∑[(pi + qi) * i] = [(p1 + q1) * 1 + (p2 + q2) * 2 + (p3 + q3) * 3 + (p4 + q4) * 4 + (p5 + q5) * 5 + (p6 + q6) * 6]
To find the expected value of a biased dice, multiply the value of each side by its respective probability of occurring and add them up. For the sum of two biased dice, calculate the expected value of each die and add them together.
Let S be the sum of numbers obtained by rolling two biased dice with possibly different biases described by probabilities pi, i = 1, 2, 3, 4, 5, 6, and qi, i = 1, 2, 3, 4, 5, 6, respectively. Then, the expected value of S can be calculated using the formula:
E(S) = E(X1) + E(X2) = ∑(pi * i) + ∑(qi * i) = ∑[(pi + qi) * i]
The probability of getting a certain sum can be calculated using the formula:
P(S = k) = ∑[pi * pj]
where i and j are the numbers on the first and second dice, respectively, and k is the sum.
In this case, the biases of the dice are described by probabilities pi, i = 1, 2, 3, 4, 5, 6, and qi, i = 1, 2, 3, 4, 5, 6, respectively. The formula for the expected value of the sum of two biased dice can be written as:
E(S) = ∑[(pi + qi) * i] = ∑[(pi + qi) * i]
The expected value of the sum of two biased dice can be calculated using the formula:
E(S) = ∑[(pi + qi) * i] = [(p1 + q1) * 1 + (p2 + q2) * 2 + (p3 + q3) * 3 + (p4 + q4) * 4 + (p5 + q5) * 5 + (p6 + q6) * 6]

what advantage does a study using multiple regression have over a study using bivariate correlation?
Multiple regression offers a more comprehensive and nuanced analysis by considering the influence of multiple predictors, capturing complex relationships, controlling for confounding variables, and enhancing predictive capabilities.
A study using multiple regression has several advantages over a study using bivariate correlation:
Multivariate analysis: Multiple regression allows for the inclusion of multiple predictor variables, which enables the examination of their individual contributions while controlling for the effects of other variables. This helps to identify the unique influence of each predictor on the outcome variable, considering their interrelationships.
Complex relationships: Multiple regression can capture complex relationships between variables by accounting for their combined effects. Bivariate correlation can only assess the linear relationship between two variables, whereas multiple regression can handle non-linear relationships and interactions between predictors.
Control of confounding variables: Multiple regression enables the control of confounding variables by including them as predictors in the model. By controlling for potential confounders, the relationship between the predictor and outcome variables can be more accurately assessed, reducing the likelihood of spurious associations.
Increased predictive power: Multiple regression can improve the predictive power of the model by incorporating multiple predictors. By considering multiple factors simultaneously, it can provide a more comprehensive understanding of the factors influencing the outcome variable and better predict its values.

if there are 30 skaters competing at the olympic games, in how many different ways can the gold, silver, and bronze medals be given?
If there are 30 skaters competing at the olympic games, then the required number of ways = 24360
The term permutation refers to a mathematical calculation of the number of ways a particular set can be arranged. Put simply, a permutation is a word that describes the number of ways things can be ordered or arranged. With permutations, the order of the arrangement matters.
Given that,
There are 30 skaters competing in the competition.
To find,
The number of ways in which they can win gold, silver, and bronze medal.
So,
We can write,
In distribution of medals(gold, silver, and bronze) we require 3 winners in a particular order, so for this we use Permutations.
According to permutation , number of ways of selecting r things out of ,
n = \(\frac{n!}{(n-r)!}\)
Then, The number of ways in which 18 skaters can win 3 medals,
= \(\frac{30!}{(30-3)!}\)
= \(\frac{30!}{27!}\)
= \(\frac{30*29*28*27!}{27!}\)
= \(30*29*28\)
= 24360
Therefore,
If there are 30 skaters competing at the olympic games, then the required number of ways = 24360

Say, for example, the correlation is 0.75 between fat content (measured in grams) and cholesterol level (measured in milligrams) for 20 different brands of American cheese slices. If cholesterol level were changed to being measured in grams (where 1 gram = 1000 milligrams), what effect would this have on the correlation?
If cholesterol level were changed to being measured in grams instead of milligrams, the correlation between fat content and cholesterol level would not be affected.
This is because correlation is a measure of the strength and direction of the linear relationship between two variables, and converting the units of measurement does not change the underlying relationship between the variables. So, the correlation coefficient of 0.75 would remain the same whether cholesterol level is measured in milligrams or grams.
The correlation between fat content and cholesterol level for the 20 different brands of American cheese slices is 0.75. If you change the measurement of cholesterol level from milligrams to grams (1 gram = 1000 milligrams), it will not affect the correlation. The correlation coefficient will remain 0.75, as it is unit-less and only represents the strength and direction of the relationship between the two variables.

Step-by-step explanation:
Make f the subject of the formula below
If we make f the subject of the formula, then f = (3 + 4d)/(3 + d)
We are given a formula in which d = 3(1 - f)/(f - 4). We have to make f the subject of the formula. To make a variable the subject of the formula, we isolate it to the left-hand side of the equation with no other variable written along with it.
So, in this question, we will isolate f on the left-hand side of the equation and we will make f the subject of the formula. We are given that
d = \(\frac{3(1-f)}{f - 4}\)
When we cross-multiply this equation, we get
d(f -4) = 3(1 -f)
fd - 4d = 3 - 3f
Combine all the terms having variable f to the left-hand side.
fd + 3f = 3 + 4d
f( d + 3) = 3 + 4d
f = \(\frac{(3 + 4d) }{(3 + d)}\)
Therefore, by making f the subject of the formula, we get
f = (3 + 4d)/(3 + d)

Use the Integrating Factor Method to solve the following differential equations: x⁴ dy/dx + 2x⁴y = x⁴e⁻ˣ
a) Rewrite the equation in Standard Form. b) Identify P(x). c) Identify Q(x). d) Evaluate Integrating Factor. e) Solve for the general solution.
The equation in Standard Form. b) Identify P(x). c) Identify Q(x). d) Evaluate Integrating Factor. e) Solve for the general solution are given below:
a) Rewrite the equation in Standard Form:
To rewrite the equation in standard form, divide the entire equation by x⁴:
dy/dx + 2y = e^(-x)
b) Identify P(x):
In standard form, the coefficient of the y term is 2, which is the function P(x). So, P(x) = 2.
c) Identify Q(x):
In standard form, the right-hand side of the equation is e^(-x), which is the function Q(x). So, Q(x) = e^(-x).
d) Evaluate the Integrating Factor:
The integrating factor (IF) is given by the exponential of the integral of P(x) with respect to x. In this case, the integrating factor is:
IF = e^(∫P(x)dx) = e^(∫2dx) = e^(2x)
e) Solve for the general solution:
Multiply the entire equation by the integrating factor (IF = e^(2x)):
e^(2x) * (dy/dx + 2y) = e^(2x) * e^(-x)
Simplify the left side by applying the product rule of exponents:
(e^(2x) * dy/dx) + 2y * e^(2x) = e^(x)
Notice that the left side is now in the form (f(x)g(x))' = f'(x)g(x) + f(x)g'(x), where f(x) = y and g(x) = e^(2x). Apply the product rule and simplify further:
(d/dx)(y * e^(2x)) = e^(x)
Integrate both sides with respect to x:
∫(d/dx)(y * e^(2x)) dx = ∫e^(x) dx
Integrating the left side gives:
y * e^(2x) = ∫e^(x) dx = e^(x) + C₁, where C₁ is the constant of integration.
Finally, solve for y by dividing both sides by e^(2x):
y = (e^(x) + C₁) / e^(2x)
This is the general solution to the given differential equation using the Integrating Factor Method.

julius has two cylinder-shaped candles of different heights and diameters. the first candle burns down in 6 hours, the second one in 8 hours. they both burn down evenly. he lights both candles at the same time and after three hours they are both equally high. what was the ratio of the original heights?
The ratio of the original heights of the two candles which are lighted at the same time is 3:4.
What is Ratio?A ratio is a quantitative relationship between two or more quantities or values, expressing how many times one quantity is contained in or is equal to another quantity.
Let the original height of the first candle as h1 and the original height of the second candle as h2.
we have,
- In six hours, the first candle is extinguished.
- The second candle burns down in 8 hours.
- After 3 hours, both candles are equally high.
From this, we can deduce that after 3 hours, both candles have burned down to the same fraction of their original heights.
For the first candle:
Remaining height of the first candle = h1/2
For the second candle:
Remaining height of the second candle = (3/8) h2
Since both candles are equally high after 3 hours, we can set up the following equation:
h1/2 = (3/8) h2
h1/h2 = (3/8) 2
h1/h2 = 3/4
Therefore, the ratio of the original heights is 3:4.

Carlos is picking 6/384 apples. Mateo is picking oranges of 10. How much did Mateo pick?
Question might be incomplete or incorrect so we'd have to assume Mateo took apples
Answer:
5/189 apples
Step-by-step explanation:
If Carlos picks 6/384 apples then there must be 384 apples available to pick from. Amount of apples left after Carlos picks =384-6=378 apples
If Mateo picks 10 apples after Carlos then how much apples Mateo has taken would depend on the number of apples available, hence the fraction of apples Mateo has taken = 10/378
Reduce to lowest terms to get 5/189 apples
