The school newspaper wants to find the opinions of students on availability of campus parking. They send a staff member to stand outside a busy dorm and interview students as they walk in or out of the building. What type of sampling process did the paper use?.

The size of the key space is 256^8, or 2^64. The average key search time would be 2^64/processing power of PC, which would be a very large number.

The question is asking about the size of the key space if 8 randomly chosen 8-bit ASCII characters are used, and how long it would take to find a key on a single PC.

The size of the key space if all 8 characters are randomly chosen 8-bit ASCII characters is 256^8 = 2^64 = 18,446,744,073,709,551,616.

The average key search time with a single PC would be 18,446,744,073,709,551,616 / 2,000,000,000,000 (2 trillion) operations per second = 9,223,372,036,854,775.8 seconds, which is approximately 292,030 years.

The size of the key space for an 8-bit ASCII character is 2^64 combinations. On average, it will take a single PC 2^64 / (processing speed of PC in Hz) seconds to search through the entire key space.

3\(x^4\) + 1 is equivalent to \(x^{(4/2)}\) in terms of asymptotic growth rate. The value of 3\(x^4\) + 1 is O(\(x^{(4/2)}\)) and \(x^{(4/2)}\) is O(3\(x^4\) + 1).

To show that 3\(x^4\) + 1 is O(\(x^{(4/2)}\)), we need to find a constant C and a value of x such that:

|3\(x^4\) + 1| <= C|\(x^{(4/2)}\)|

For x >= 1, we can say that:

3\(x^4\) + 1 <= 4\(x^4\)

Taking the square root of both sides, we get:

sqrt(3\(x^4\) + 1) <= 2x²

Thus, we can choose C = 2 and x0 = 1, and we have:

|3\(x^4\) + 1| <= 2|\(x^{(4/2)}\)| for all x >= 1

Therefore, 3\(x^4\) + 1 is O(\(x^{(4/2)}\)).

To show that \(x^{(4/2)}\) is O(3\(x^4\) + 1), we need to find a constant C and a value of x such that:

|\(x^{(4/2)}\)| <= C|3\(x^4\) + 1|

For x >= 1, we can say that:

\(x^{(4/2)}\) <= x²

Thus, we can choose C = 1 and x0 = 1, and we have:

|\(x^{(4/2)}\)| <= |3\(x^4\) + 1| for all x >= 1

Therefore, \(x^{(4/2)}\) is O(3\(x^4\) + 1).

Since both 3\(x^4\) + 1 is O(\(x^{(4/2)}\)) and \(x^{(4/2)}\) is O(3\(x^4\) + 1).

The least positive integer multiple of 30 that can be written with only the digits 0 and 2 is 2220.

We can approach this problem by observing that a multiple of 30 must be divisible by both 2 and 3. A number is divisible by 2 if its last digit is even, which in this case means it must be 0 or 2. A number is divisible by 3 if the sum of its digits is divisible by 3.

The last digit of multiple of 30 is 0.

Since the sum of the digits must be divisible by 3, the digit 2 should be at least 3.

Let's check the following number that satisfies the above conditions:

2220

The sum: 2 + 2 + 2 + 0 = 6 (divisible by 3)

Let's check whether 2220 is a multiple of 30,

2220 : 30 = 74

Hence, it is a multiple of 30.

Answer:

x = y = 20

Step-by-step explanation:

The two triangles shown are similar because one is simply an extension of othe other.

From this, we can use a similar side lengths formula specifically for triangles.

\(\frac{y + 5}{y} = \frac{15}{12}\\\)

Notice that this represents the ratio of the whole side to the smaller side and says that this proportion is equal to the proportion for its adjacent side lengths. Cross mutiply the above equation to solve for y.

12(y+5) = 15y

12y + 60 = 15y

y = 20

Now we need to find the value of x. We have a side and hypotenuse's length of this large triangle, so we can use the pythagorean theorem to calculate the unknown side length.

(12 + 3)² + x² = (20 + 5)²

15² + x² = 25²

225 + x² = 625

x² = 400

x = ±20

The negative 20 doesn't make sense for this application so use the positive 20.

Therefore x = 20, y = 20.

The correct option is B, A hypothesis is a conjecture by the researcher about the connection between multiple fluctuating factors.

A hypothesis is a proposed explanation or prediction for a phenomenon or set of phenomena based on limited evidence or initial observations. It is a tentative explanation that must be tested and evaluated before it can be accepted or rejected.

A good hypothesis is testable, falsifiable, and based on available evidence or prior knowledge. It should also be specific, clear, and able to be repeated by other researchers to verify the results. Hypotheses are used in scientific research to guide the design of experiments or studies, and to help researchers determine the most effective ways to test their ideas. Once a hypothesis has been formulated, it can be tested through experimentation or observation.

Step-by-step explanation:

We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4

Answer: 6 inches

Step 1: Subtract 12 because 12 iches is the base.

24 - 12 = 2

Step 2: Divide 12 by 2 because triangles have two equal sides.

12 ÷ 2 = 6

Answer:

133, 79, 148 are ALL possible, so select 133 and 79

Step-by-step explanation:

Subtract 47 and 32 from 180 to find the third angle of the triangle (it is 101).

Then do 180-101 = 79

180-32=148

180-47=133

That tells you the exterior angle of each. Only two possible choices on your list.

Answer:

h = 3, k = 64

Step-by-step explanation:

Given

\(log_{2}\) y = - \(\frac{1}{2}\) \(log_{2}\) x + 3

In the form

y = mx + c ( m is the slope and c the y- intercept )

Then

h = 3

On the \(log_{2}\) axis \(log_{2}\) y = 0 then

0 = - \(\frac{1}{2}\) \(log_{2}\) k + 3 ( subtract 3 from both sides )

- 3 = - \(\frac{1}{2}\) \(log_{2}\) k ( divide both sides by - \(\frac{1}{2}\) )

6 = \(log_{2}\) k , then

k = \(2^{6}\) = 64

Answer:

C

Step-by-step explanation:

Answer:

An equation in the form y = mx + b is in the 'slope y-intercept' form where m is the slope and b is the y-intercept. We can rewrite our equation, y = 4, in slope y-intercept form as follows: y = 0x + 4. Here, it is clear that the slope, or m, is zero. Therefore, the slope of the horizontal line y = 4 is zero

Answer:

4

Step-by-step explanation:

Constant of proportionality is the same as slope in the context of a linear function, which is defined as Δy / Δx. We can find this by taking two points and finding the difference in their x- and y-coordinates.

I'll use (1, 4) and (2, 8).

\(\textrm{slope}=\dfrac{8-4}{2-1} = \dfrac{4}{1} = 4\)

The volume of a cone with the same radius and height as a cylinder with volume 300 is 100.

What is the Volume?

Volume is a measure of the amount of space that an object occupies. It is a three-dimensional measurement that is typically expressed in cubic units.

A cylinder with volume 300 and radius "r" has a height "h" given by the formula:

V = πr²h

So, h = V / (πr^2) = 300 / (πr²).

A cone with the same radius "r" and height "h" as the cylinder has a volume given by the formula:

V = (1/3)πr²h

Plugging in the values of "r" and "h" obtained above, we get:

V = (1/3)πr²h = (1/3)πr² (300 / (πr²)) = 100.

Hence, the volume of a cone with the same radius and height as a cylinder with volume 300 is 100.

The features of the genetic code that support the hypothesis of the triplet genetic code evolving from a two-nucleotide code are the degeneracy and universality of the genetic code.

The genetic code is degenerate, meaning that multiple codons can code for the same amino acid. For example, the amino acid leucine is coded by six different codons. This suggests that the genetic code could have started with fewer amino acids, and as more amino acids evolved, the code expanded to accommodate them. Additionally, the genetic code is universal, meaning that it is shared by almost all organisms on Earth. This universality suggests that the genetic code has ancient origins and has been conserved throughout evolution. These features of the genetic code support the hypothesis that it evolved from a simpler, two-nucleotide code with fewer amino acids.

In summary, the degeneracy and universality of the genetic code provide evidence to support the hypothesis that the triplet genetic code evolved from a two-nucleotide code with fewer amino acids. The degeneracy of the code suggests that it could have expanded to accommodate more amino acids over time, while the universality of the code implies ancient origins and conservation throughout evolution.

We have to rank the tools from the one that is least precise to the one that is the most precise.

The precision depends on the smallest unit that the tool can measure.

In this list, the least precise is the highway mile marker, as it can not measure nothing that is less than a mile.

Next is the five-foot branch, as anything with a length less than 5 foot can not be precisely measured with this.

Next is the length of a persons foot, with a precision of one foot.

Lastly, the yardstick, that has precision of fractions of inches.
