Answer:
Step-by-step explanation:
Since (fn) converges pointwise to the zero function, we have that for every x ∈ X,
limn→∞ fn(x) = 0.
Now, for each n ∈ N, we have fn ≥ 0 and thus, max{f1, ..., fn} = fn.
Therefore,
∫max{f1, ..., fn} dμ = ∫fn dμ.
Since ∫max{f1, ..., fn} dμ ≤ M < ∞, we have that ∫fn dμ ≤ M for all n ∈ N.
We can use the dominated convergence theorem to show that
limn→∞ ∫fn dμ = ∫limn→∞ fn dμ = 0.
To apply the dominated convergence theorem, we need to find a dominating function that is integrable and dominates fn for all n. Since fn ≥ 0 for all n, we can take g = max{f1, f2, ...} as our dominating function.
Then, we have that g ≥ fn for all n, and
∫g dμ = ∫max{f1, f2, ...} dμ ≤ M < ∞.
Therefore, g is integrable and dominates fn for all n, and we can apply the dominated convergence theorem to conclude that
limn→∞ ∫fn dμ = ∫limn→∞ fn dμ = 0.

Step-by-step explanation:
For her father's birthday, Jeanna wishes to bake 34 pans of
baked macaroni. However, her small oven can bake one pan
only for 1 hours. How many hours will it take Jeanna to bake 3
pans of baked macaroni?
2
11
It will take 3 hours to bake 3 pans of baked macaroni if the oven can only bake one pan of baked macaroni for 1 hour.
If Jeanna's oven can only bake one pan of baked macaroni for 1 hour, then it will take 3 hours to bake 3 pans of baked macaroni. This is because the time it takes to bake the pans is directly proportional to the number of pans being baked. Therefore, if it takes 1 hour to bake 1 pan, it will take 3 hours to bake 3 pans. So, the answer is 3 hours.
It is important to note that the number of pans Jeanna wishes to bake, which is 34 pans, is irrelevant to the question. The question only asks for the time it will take to bake 3 pans of baked macaroni, so the number of pans Jeanna wishes to bake does not affect the answer.

Step-by-step explanation:
I'm going to assume that you meant 3.14 by 3,14.
336,765 = 3.14 × 0.55 × (l + 0.55)
336,765 ÷ (3.14 × 0.55) = l + 0.55

Heights, in inches, for the 200 graduating seniors from Washington High School are summarized in the frequency table below.
Which of the following statements about the median height is true?
answer choices
It is greater than or equal to 72 inches but less than 78 inches.
It is greater than or equal to 66 inches but less than 72 inches.
It is less than 60 inches.
It is greater than or equal to 60 inches but less than 66 inches.
Option (D), the last option is the correct statement, If heights in inches of 200 graduating seniors were summarized in the frequency table;
The median height is greater than or equal to 60 inches but less than 66 inches.
The median is the number value that separates the lower and upper values to halves. The median height is determined by arranging all the given heights in order either from the smallest to highest or from highest to smallest without skipping any measurement of the heights.
After arranging all the heights in order, the median height is usually at the middle.
The reason as to why the median height is greater than or equal to 60 inches but less than 66 inches is because the middle height should not be same as the largest height of 66 inches. It is possible to have multiple 60 inch heights from the 200 seniors. It is also possible to have multiple 66 inch of heights from the 200 seniors.

5 companies have 0 computers.
10 companies have 1 computer.
10 companies have 2 computers.
30 companies have 3 computers.
25 companies have 4 computers.
20 companies have 5 computers.
To find mean:
0 x 5 = 0
10 x 1 = 10
10 x 2 = 20
30 x 3 = 90
25 x 4 = 100
20 x 5 = 100
100 + 100 + 90 + 20 + 10 + 0 = 320
20 + 25 + 30 + 10 + 10 + 5 = 100
100 companies were surveyed.
100 companies use 320 computers in total.

Some nations require their students to pass an exam before earning their primary school degrees or diplomas. A certain nation gives students an exam whose scores are normally distributed with a mean of 414141 points and a standard deviation of 999 points. Suppose we select 222 of these testers at random, and define the random variable ddd as the difference between their scores. We can assume that their scores are independent. Find the probability that their scores differ by more than 151515 points.
The required probability that their scores differ by more than 15 points is 0.99807.
As stated in the question, a specific country administers an exam to students with scores that are regularly distributed with a mean of 41 points and a standard deviation of 9 points. Assume we randomly select two of these testers and define the random variable d as the difference in their scores.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Z = x - μ / σ
Z = 15 - 41 / 9
Z = -2.88
Now,
P(x > 15) = P (z > -2.88)
= 0.99807

a system consists of 5 identical components. in order for the system to perform as intended, all of the components must perform. each has the same probability of performance. if the system is to have a 0.91 probability of performing, what is the minimum probability of performing needed by each of the individual components?
The minimum probability of performance needed by each of the individual components is approximately 0.976.
Since the system consists of 5 components that must all perform for the system to work, the probability of the system performing can be expressed as the product of the probability of each component performing:
P(system performs) = P(component 1 performs) x P(component 2 performs) x ... x P(component 5 performs)
Since all components are identical, we can express the probability of each component performing as x, and the probability of the system performing as:
P(system performs) = \(x^5\)We want the probability of the system performing to be at least 0.91. Therefore, we can set up the following equation:
\(x^5\) ≥ 0.91Taking the fifth root of both sides gives us:
x ≥ \(0.91^{(1/5)}\)x ≥ 0.9759Therefore, the minimum probability of performance needed by each of the individual components is approximately 0.976.

If a number does not have exactly two distinct factors, then the number is not prime.
If a number is not prime, then the number does not have exactly two distinct factors.
If a number is prime, then the number has exactly two distinct fac
The inverse of the statement is "If a number does not have exactly two distinct factors, then the number is not prime." Thus Option 2 is the answer.
When a conditional statement is reversed, the hypothesis and conclusion are both negated. The hypothesis in the original statement is "a number with exactly two distinct factors," while the conclusion is "is prime."
To make the inverse, we negate both sections. "A number does not have exactly two distinct factors" is the antonym of "A number that has exactly two distinct factors." "Is not prime" is the opposite of "is prime."
As a result, the inverse statement is "If a number does not have exactly two distinct factors, then the number is not prime."
It's crucial to remember that a statement's inverse could or might not be accurate. In this instance, the inverse is true since the definition of a prime number is incompatible with the fact that a number has more than two components if it has more than exactly two different factors.

Answer:
B
Step-by-step explanation:
When numbers are negative, the number that has the bigger absolute value(meaning the actual number without the negative sign) is smaller because it is farther down from 0. So, -19% is less than -1.75%.
Negative numbers are always less than positive ones, so now, we know that the other two values are greater than the negative ones.
Now, if you convert 9/11 to decimals, you will get 0.818181818181818181...
Which is 0.008181818181... greater than 0.81. So, the final answer is...
-19% < -1.75% < 0.81 < 9/11
Ascending means increasing.
As you can see, each value in the expression -19% < -1.75% < 0.81 < 9/11 is greater than the value before it, so therefore...

how do I find the inverse function of
To find the inverse function of F(x) = 2x - 3, we replace F(x) with y, swap the positions of x and y, and solve for y. The inverse function is f⁻¹(x) = (x+3)/2.
To find the inverse function of F(x) = 2x - 3, follow these steps
Replace F(x) with y. The equation now becomes y = 2x - 3.
Switch the positions of x and y, so the equation becomes x = 2y - 3.
Solve for y in terms of x. Add 3 to both sides: x + 3 = 2y.
Divide both sides by 2 (x + 3)/2 = y.
Replace y with the notation for the inverse function, f⁻¹(x): f⁻¹(x) = (x + 3)/2.
So, the inverse function of F(x) = 2x - 3 is f⁻¹(x) = (x + 3)/2.

It is meaningful to compute the probability that a continuous random variable is greater than or equal to a number, less than or equal to a number, or between two numbers.
What is indetail explaination of the answer?In probability theory, a continuous random variable is a variable that can take on any value within a certain range or interval.
As a result, the probability that a continuous random variable takes on a specific value is zero, since there are infinitely many possible values the variable can take on.
Therefore, it is not meaningful to compute the probability that a continuous random variable is exactly equal to a number.
However, it is meaningful to compute the probability that a continuous random variable is greater than or equal to a number, less than or equal to a number, or between two numbers.
These probabilities can be calculated using the cumulative distribution function (CDF) of the random variable. The CDF gives the probability that a random variable takes on a value less than or equal to a certain value, which can be used to compute probabilities for ranges of values.

prove the identity ((secy-tany) (secy+ tan y))/secy= COS U
Answer:
boring
Step-by-step explanation:
To prove the given identity, we'll start with the left side and simplify it step by step until we obtain the right side of the equation:
We have:
((sec y - tan y)(sec y + tan y)) / sec y
Using the difference of squares, we can rewrite the numerator:
((sec y)^2 - (tan y)^2) / sec y
Recall the trigonometric identity: (sec x)^2 - (tan x)^2 = 1
Substituting this identity into our expression:
(1) / sec y
Using the reciprocal identity: sec x = 1 / cos x
We can rewrite the expression as:
1 / (1 / cos y)
Simplifying further by multiplying by the reciprocal:
cos y / 1
Which simplifies to:
cos y
Therefore, we have shown that the left side of the identity ((sec y - tan y)(sec y + tan y)) / sec y simplifies to cos y, which is the same as the right side of the equation.
