what is derivative?The derivative of a function with real variables in mathematics gauges how sensitively the function's value will change in response to changes in its arguments. Calculus's fundamental tools are derivatives. Differentiation (in mathematics, the rate of change of a function with respect to a variable) (in mathematics, the rate of change of a function with respect to a variable). Calculus and differential equation problem-solving depend heavily on derivatives. Finding the "slope" of a specific function is the definition of "derivative" or "taking a derivative" in calculus. Because it is often the slope of a straight line, the slope should be enclose in quotations. While applying to practically every function, derivatives are measures of rate of change.

You can model the population of a certain city between the years 1970 and 1955 by the radical function P(x)=80000x−1940√3 . Using this model, in what year was the population of that city 290,000?
The year the population of that city was 290,000 is 1988.
What year was the population of that city 290,000?A model function is a mathematical or computational representation of a system or process that is designed to capture its behavior, relationships, and interactions.
The model is p(x) = 80,000 ∛(x - 1940)
Now use p(x) = 290,000and solve for x
290,000 = 80,000 ∛(x - 1940) =
290,000 / 80,000 = ∛(x - 1940)
29/8 = ∛(x - 1940)
x - 1940 = [29/8]³
x - 1940 = 47.63
x = 1940 + 47.63
x = 1987.63
Therefore, the year is 1988

Patients coming to a medical clinic have a mean weight of 207.6 pounds, with a standard deviation of 22.6 pounds. The distribution of weights is not assumed to be symmetric.
Between what two weights does Chebyshev's Theorem guarantee that we will find at least 95% of the patients?
Round your answers to the nearest tenth. Enter the pounds in ascending order.
Between 105.9 and 309.3 pounds, Chebyshev's Theorem guarantee that we will find at least 95% of the patients.
k = 4.5.
Weight 4.5 standard deviations below the mean is 207.6 − 4.5 (22.6) = 105.9 pounds.
Weight 4.5 standard deviations above the mean is 207.6 + 4.5 (22.6) = 309.3 pounds.
Therefore, at least 95% of patients weigh between 105.9 and 309.3 pounds.
About Chebyshev theoremIn probability theory, the Chebyshev inequality guarantees that for any sample data or probability distribution, nearly all values are close to the mean. Precisely, that no more 1/k2 of the distribution value exceeds the k standard deviation.
Chebyshev's inequality theorem can be used to find the probability range for an unknown distribution based on its mean and variance.
Chebyshev is named after a Russian mathematician, although the first formulation of the inequality was obtained from his colleague, Irénée-Jules Bienaymé. Chebyshev's inequality theorem was introduced without any proof in 1874, which later, in 1884,
Chebyshev's student, Andrey Markov presented a proof. Therefore, in the context of the analysis, the Chebyshev inequality is also expressed in the Markov inequality.

For the given number line plot the inequality obtained is { -∞ < x < -2 and 5 < x < ∞}.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
To represent inequalities on a number line show the range of numbers by drawing a straight line and indicating the end points with either an open circle or a closed circle.
An open circle shows it does not include the value.
A closed circle shows it does include the value.
Let the unknown value be x.
The first range is starting form -2 and moving towards -∞.
Since the circle is open it will not include the value.
So the inequality is -∞ < x < -2.
The second range is starting form 5 and moving towards ∞.
Since the circle is open it will not include the value.
So the inequality is 5 < x < ∞.
Therefore, the inequality is { -∞ < x < -2 and 5 < x < ∞}.

British sterling silver is a copper-silver alloy that is 7.5% copper by weight. How many grams of pure copper and how many grams of British sterling silver should be used to prepare 330 grams of a copper-silver alloy that is 10% copper by weight? (Round your answers to one decimal place.)
British sterling silver ____________ g
Copper ___________g
British sterling silver = 321.1 grams
Copper = 8.9 grams
========================================================
Work Shown:
x = amount of British sterling silver (in grams)330-x = amount of pure copper (in grams)The two amounts add to 330 grams total. The x is some number in the interval 0 < x < 330.
7.5% of x = 0.075x = amount of pure copper from the British sterling0.075x+(330-x) = -0.925x+330 = total amount of pure copperWe want to end up with 330 grams of 10% copper, so we want 0.10*330 = 33 grams of pure copper after mixing the two metals.
Set the 33 equal to the expression -0.925x+330 and solve for x.
-----------
-0.925x+330 = 33
-0.925x = 33-330
-0.925x = -297
x = -297/(-0.925)
x = 321.081 approximately
x = 321.1 when rounding to one decimal place
330-x = 330-321.1 = 8.9
-----------
We'll need 321.1 grams of British sterling silver.
We'll also need 8.9 grams of pure copper.

In a sample of size 100 how many observations are below the median? How many are between the median and Q1 (first quartile)? How many are in the IQR? The numbers are listed in the order in which the questions are asked.
Group of answer choices
50, 50, 100
50, 25, 50
50, 75, 25
25, 50, 75
In a sample of size 100, the median splits the data into two equal parts of 50 observations each. So, 50 observations are below the median and 50 observations are above the median.
The first quartile (Q1) separates the lowest 25% of the data from the rest, so 50 observations are between the median and Q1.
The interquartile range (IQR) is defined as the difference between the third quartile (Q3) and Q1, and represents the range of the middle 50% of the data. Since the IQR contains both Q1 and the median, it encompasses all observations between Q1 and the median,
or a total of 75 observations.

A metallurgist has one alloy containing 35% titanium and another containing 69% titanium. How many pounds of each alloy must he use to make 53 pounds of a third alloy containing 40% titanium?
Answer:
Let x be the amount of alloy 1 used, and y be the amount of alloy 2 used.
We know that:
x + y = 53 (total weight of alloy 3 is 53 pounds)
0.35x + 0.69y = 0.40(53) (40% of the alloy 3 is titanium)
We can use the first equation to solve for one of the variables in terms of the other:
y = 53 - x
Substitute this expression into the second equation:
0.35x + 0.69(53-x) = 0.40(53)
0.35x + 36.97 - 0.69x = 21.2
-0.34x = -15.77
x = 46.44 pounds of alloy 1.
y = 53 - x = 6.56 pounds of alloy 2.

Exercise 1: Your friends are organizing a trip for the upcoming spring break. They are
undecided between visiting a national park or visiting a city in the USA. The probability your
friends decide to visit a national park is .35. If your friends decide to visit a national park, the
probability you will join them is .75. On the other hand, if your friends decide to visit a city in
the USA, the probability you will join them is .40.
a) What is the probability you will join them? (Hint: the appropriate visualization
tool might be helpful).
b) If you end up joining them, what is the probability your friends have decided to
visit a national park?
A) The probability that you will join them is 0.523;
B) If you end up joining them, the probability your friends have decided to visit a national park is 0.50.
What is probability?Note that probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
In the above case, Note that to determine the probability that you will join them, we need to use the formula for conditional probability, which is:
P(A and B) = P(A|B) * P(B)
In this case, A is the event that you join them, and B is the event of your friends deciding to visit either a national park or a city in the USA.
Given the above, we have:
P(join and national park) = P(join|national park) * P(national park) = 0.75 * 0.35
P(join and city) = P(join|city) * P(city) = 0.40 * 0.65
Thus to obtain the probability that you will join them: we must add the two probabilities: P(join and national park) and P(join and city)
⇒ P(join) = P(join and national park) + P(join and city)
= 0.75 * 0.35 + 0.40 * 0.65
= 0.523
Thus, it is correct to state that the probability or likelihood that you join them is: 0.523
B) If you decide to join them, the probability that your friends have decided to go to a national park is determined using the Bayes Theorem. This theorem is given as:
P(B|A) = P(A|B) * P(B) / P(A)
Where A is the event of you going with them, and B is the event of your friends deciding to go to a national park.
P(national park|join) = P(join|national park) * P(national park) / P(join)
= 0.75 * 0.35 / 0.525
= 0.5019120459
[tex]\approx[/tex] 0.50
Thus, it is correct to state that the probability your friends have decided to visit a national park is 0.57 if you eventually join them.
