Notation refers to a system of symbols or characters used to represent something. In the context of computational complexity theory, notation is used to describe the complexity of algorithms and problems. In particular, it is used to describe the complexity of polynomial time reductions between problems. A polynomial time reduction from problem A to problem B means that there exists an algorithm that can transform an instance of problem A into an equivalent instance of problem B in polynomial time. If there is no polynomial time reduction from problem A to problem B, we say that there is no polynomial time reduction exist from A to B. Therefore, the correct option is "it means that there is no a polynomial time reduction exist from a to b."

It means that there exists a polynomial time reduction from A to B.

In this context, a polynomial time reduction is a method of transforming one problem (A) into another problem (B) using a process that takes polynomial time. The notation indicates that there is an efficient algorithm for converting A to B, so if we can solve problem B efficiently, we can also solve problem A efficiently.

We must conclude that there are infinitely many primes of the form 3k + 2, where k is a non-negative integer.

To adapt the proof:

We can use a similar contradiction argument.

Suppose that there are only finitely many primes of the form 3k + 2, say p1, p2, ..., pn.

Let N = 3p1p2...pn + 2. Note that N is of the form 3k + 2 for some non-negative integer k.

Now, let's consider the prime factorization of N. Either N is prime and of the form 3k + 2, in which case we have found a new prime of the desired form, contradicting our assumption that there are only finitely many such primes. Or, N is composite and has a prime factorization consisting only of primes of the form 3k + 1 (since any prime of the form 3k + 2 would divide N). But this implies that N itself is of the form 3k + 1.

Now, let's consider the number M = 3N + 2. M is also of the form 3k + 2, and so must have a prime factorization consisting only of primes of the form 3k + 1. But since N is of the form 3k + 1, we have

M = 3(3p1p2...pn + 1) + 2 = 9p1p2...pn + 5. This means that M has a prime factorization consisting of primes of the form 3k + 2, which contradicts our assumption that there are only finitely many such primes.

Therefore, we must conclude that there are infinitely many primes of the form 3k + 2, where k is a non-negative integer.

4370 cannot be represented as a sum of any two squares, but 1885 and 3185 can be written as a sum of two squares.

To determine which of the numbers 4370, 1885, 3185 can be represented as a sum of any two squares, we need to check if they can be expressed in the form of a^2 + b^2, where a and b are integers.

For 4370, we can start by checking the squares of integers up to the square root of 4370, which is approximately 66. Since 4370 is not a perfect square, we can check for all pairs of integers up to 66 and see if their sum of squares equals 4370. After checking all possibilities, we find that there are no two squares that add up to 4370.

For 1885 and 3185, we can repeat the same process and find that both of them can be represented as the sum of two squares. Specifically, 1885 can be written as 34^2 + 17^2 and 3185 can be written as 47^2 + 36^2.

The difference between this problem and ps4, problem 4 is that in ps4, problem 4, we were asked to find all possible pairs of integers a and b such that a^2 + b^2 = 2021. In this problem, we are asked to determine which of the given numbers can be represented as a sum of any two squares.

Y has the same distribution function as the original distribution function F.

Let Y = F^(-1)(U), where U is uniformly distributed on (0,1) and F^(-1) is the inverse function of F.

We want to find the distribution function of Y.

Let y be any real number. Then we have:

F_Y(y) = P(Y ≤ y)

= P(F^(-1)(U) ≤ y)

Since F is a continuous distribution function, it is also an increasing function. Therefore, the inverse function F^(-1) is also an increasing function.

Thus, we can apply the inverse function F^(-1) to both sides of the inequality F^(-1)(U) ≤ y without changing the direction of the inequality:

P(U ≤ F(y)) = F(y)

Therefore,

F_Y(y) = P(F^(-1)(U) ≤ y)

= P(U ≤ F(y))

= F(y)

Hence, the distribution function of Y is F_Y(y) = F(y) for all real numbers y.

The value of c in the given function  f(x)={-x³, xc}  that makes the function f(x) continuous is calculated to be c = -1.

For the function f(x) to be continuous, it must be true that:

lim x→c- f(x) = lim x→c+ f(x) = f(c)

Let's first find lim x→c- f(x):

lim x→c- f(x) = lim x→c- (-x³) = -c³

Now, let's find lim x→c+ f(x):

lim x→c+ f(x) = lim x→c+ (xc) = c²

For f(x) to be continuous, it must be true that:

-c³ = c²

Multiplying both sides by -1, we get:

c³ = -c²

Dividing both sides by c² (note that c cannot be 0), we get:

c = -1

a. To find the t-test statistic, we first need to calculate the standard error of the mean using the formula: standard deviation / square root of sample size. In this case, the standard error of the mean is 600 / square root of 50, which is approximately 84.85.

Then, we can calculate the t-test statistic using the formula: (sample mean - hypothesized population mean) / standard error of the mean. In this case, the t-test statistic is (2450 - 2600) / 84.85, which is approximately -1.77.

b. To find the P-value, we need to consult a t-distribution table or use statistical software. Using a two-tailed t-test with 49 degrees of freedom (50-1), we find that the P-value associated with a t-test statistic of -1.77 is approximately 0.084. Therefore, there is a 8.4% chance of obtaining a sample mean of $2,450 or less if the true mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year is actually $2,600.

Note: A common threshold for statistical significance is a P-value of less than 0.05. Since the P-value in this case is greater than 0.05, we cannot reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year is different from $2,600.
a. To find the t-test statistic, we will use the following formula:

t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size))

Here, sample mean = $2,450, population mean = $2,600, sample standard deviation = $600, and sample size = 50.

t = ($2,450 - $2,600) / ($600 / sqrt(50))
t = (-$150) / ($600 / 7.071)
t = (-$150) / $84.85
t ≈ -1.77

The t-test statistic is approximately -1.77.

b. To find the P-value, we need to use a t-distribution table or software to determine the probability of obtaining a t-test statistic as extreme or more extreme than our calculated value. We are doing a two-tailed test, so we need to find the area in both tails.

Looking up the t-test statistic -1.77 in a t-distribution table with 49 degrees of freedom (sample size - 1), we find the P-value is between 0.05 and 0.10. For a more accurate P-value, use software or an online calculator.

So, the P-value is between 0.05 and 0.10.

The following statement is true. All other things being equal in constructing a confidence interval for a population proportion, the confidence interval constructed using a sample size of n = 500a compared to n = 200 will be a better estimate for the population proportion.

That is, the confidence interval will have a shorter length. A confidence interval is a range of values that is likely to contain the true value of a population parameter with a certain level of confidence, based on a sample of data. It is commonly used in inferential statistics to estimate the range of values for a population parameter, such as a mean or proportion, based on sample data.

A confidence interval is typically represented by two values, an upper limit and a lower limit, and a confidence level, expressed as a percentage. The confidence level indicates the probability that the true population parameter falls within the interval. For example, a 95% confidence interval indicates that there is a 95% probability that the true population parameter falls within the interval.

The width of the confidence interval depends on the sample size, the variability of the data, and the chosen level of confidence. As the sample size increases, the width of the interval decreases, while increasing the level of confidence increases the width of the interval.

Step-by-step explanation:

The length of f is 11.9 ft.

We have,

d = 5.2 inches, e = 6.8 inches and ∠F=166°.

f² = d² + e² - 2(de)(cos(F))

So, f² = (5.2)² + (6.8)²  - 2(5.2)(6.8)cos(166)

f² = 27.04 + 46.24 - 66.56 cos (166)

f² = 73.28 - 66.56 cos 166
