The virus I suggest stay home.

A Turing machine is a mathematical model of computation that is a simple hypothetical device that operates on an infinite tape of cells, where each cell can contain a symbol from a finite set of symbols.

Here is how you can construct a Turing machine that adds a 1 to the end of a bit string without changing any of the other symbols on the tape:

1. Start by placing a marker on the leftmost symbol of the input bit string. This marker will be used to indicate the end of the bit string.

2. Move the tape head to the right until it reaches the marker.

3. Once the tape head is on the marker, overwrite it with a 1.

4. Move the tape head back to the leftmost symbol of the input bit string.

5. Now, move the tape head to the right until it reaches the end of the input bit string (which is now a 1).

6. Place another marker on the new end of the bit string.

7. Move the tape head back to the leftmost symbol of the input bit string.

8. Finally, move the tape head to the right until it reaches the second marker. Once the tape head is on the second marker, halt the Turing machine.

This Turing machine will add a 1 to the end of a bit string without changing any of the other symbols on the tape. Note that this Turing machine assumes that the input bit string is non-empty and consists only of 0s and 1s.

Step-by-step explanation:

Answer:

I think C is your answer.

Step-by-step explanation:

The average speed of the first plane is 339.5 mph, and the average speed of the second plane is 97 mph.

To find the average speed of each plane, we can use the formula:

Speed = Distance / Time

Let's assign variables to the speeds of the two planes. Let's say the speed of the second plane is 'x' mph. Since the first plane is traveling 3.5 times as fast, the speed of the first plane would be 3.5x mph.

Now, we know that both planes have traveled for 6 hours and are 1455 miles apart. Since they are traveling in the same direction, the distance between them will be the difference of their distances. Therefore, we have:

Distance of the first plane = 3.5x * 6 = 21x miles
Distance of the second plane = x * 6 = 6x miles

The difference between their distances is 1455 miles, so we can set up the equation:

21x - 6x = 1455

Combining like terms, we get:

15x = 1455

Dividing both sides by 15, we find:

x = 97

So, the speed of the second plane is 97 mph, and the speed of the first plane is 3.5 * 97 = 339.5 mph.

For the lengths of short stories (number of words), appropriate intervals for organizing the data in a frequency table could be:

0-200 words

201-400 words

401-600 words

601-800 words

801-1000 words

To create intervals for the lengths of short stories, we consider the range of values present in the data set. The minimum value is 120 words, and the maximum value is 922 words. By dividing the range into equal intervals, we can create appropriate intervals for the frequency table.

In this case, we divide the range of 922 - 120 = 802 words into 5 equal intervals, resulting in an interval width of 802 / 5 = 160.4 words. Since we cannot have a fractional number of words, we can round up to the nearest whole number and set the interval width to 161 words.

Starting from the minimum value of 120 words, we can organize the intervals as follows:

0-200 words

Includes values from 120 to 280 words (120 + 161)

201-400 words

Includes values from 281 to 441 words (280 + 161)

401-600 words

Includes values from 442 to 602 words (441 + 161)

601-800 words

Includes values from 603 to 763 words (602 + 161)

801-1000 words

Includes values from 764 to 924 words (763 + 161)

By using these intervals, we can create a frequency table that shows the number of short stories falling within each interval.

Note: The intervals can be adjusted based on the specific requirements or preferences of the analysis.

The sample mean is c) M=51.

To find the sample mean, we can use the formula for z-score:
                                              z = (X - M) / s

where:

In this case, we have two equations with two unknowns:

-0.25 = (M - 3 - M) / s
-0.75 = (44 - M) / s

Multiplying both sides of the first equation by s gives us:
-0.25s = M - 3 - M

Simplifying gives us:
-0.25s = -3

Next, we can multiply both sides of the second equation by s:
-0.75s = 44 - M

Now we can substitute the value of s from the first equation into the second equation:
-0.75(-3 / 0.25) = 44 - M

Simplifying gives us:
9 = 44 - M

Finally, we can solve for M:
M = 44 - 9
M = 35

So the sample mean is 35.

Step-by-step explanation:

Exponential Function

General form of an exponential function: \(y=ab^x\)

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

Given information:

Therefore:  \(y=240b^x\)

To find an expression for the population after 1 hour, substitute x = 1 into the found equation:

\(\implies y=240b^1\)

\(\implies y=240b\)

We are told that the population after 9 hours is double the population after 1 hour.  Therefore, make y equal to twice the found expression for the population after 1 hour, let x = 9, then solve for b:

\(\implies 2(240b)=240b^9\)

\(\implies 480b=240b^9\)

\(\implies 480=240b^8\)

\(\implies 2=b^8\)

\(\implies b=\sqrt[8]{2}\)

\(\implies b=2^{\frac{1}{8}}\)

Therefore, the final exponential equation modelling the given scenario is:

\(\implies y=240(2^{\frac{1}{8}})^x\)

\(\implies y=240(2)^{\frac{1}{8}x}\)

To find how many bacteria there will be after 4 hours, substitute x = 4 into the found equation:

\(\implies y=240(2)^{\frac{1}{8}(4)}\)

\(\implies y=240(2)^{\frac{1}{2}}\)

\(\implies y=339 \:\: \sf (nearest\:whole\:number)\)

We assume that G is a connected planar graph with no vertex of degree <= 5. We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices. Let d be the maximum degree of G.

Qa. Contrapositive of an implication is a new implication formed by negating both the hypothesis and the conclusion.

The contrapositive of the implication "If G is a connected planar graph, then G has at least one vertex of degree <= 5" is "If G has no vertex of degree <= 5, then G is not a connected planar graph."

Qb. Proof: We assume that G is a connected planar graph with no vertex of degree <= 5.

We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices.

Let d be the maximum degree of G. Since G has no vertex of degree <= 5, then d >= 6.

Thus, the sum of degrees of all vertices in G is greater than or equal to 6v/2, which is equal to 3v.

Hence, 2e >= 3v.

Substituting this inequality in e <= 3v - 6, we get 2e >= 3e - 6, which implies that e >= 6.

Since e >= 6, it follows that G is not planar.

Qc. Proof: We use proof by induction on the number of vertices of G. For a graph with one vertex, the statement is trivially true.

For a graph with n > 1 vertices, assume that every planar graph with at most n - 1 vertices can be colored with 6 (or less) colors.

Let G be a planar graph with n vertices.

By part (a), there exists a vertex v of G with degree <= 5.

We remove v and all its edges from G to get a new graph G' with n - 1 vertices.

By the induction hypothesis, we can color G' with 6 (or less) colors.

We add back v and its edges to G.

Since v has degree <= 5, at most 5 colors are used on its adjacent vertices.

We use a new color for v.

Thus, G can be colored with 6 (or less) colors.

Therefore, by induction, the statement is true for all planar graphs.
