The speed limit is 35 MPH. What is the translation?

I NEED IT NOW

GO GO GO GO

Answers

Miles Per Hour is the translation

The speed limit of 35 mph translates to approximately 56.327 km/hr.

The translation of the car's speed from kilometers per hour to miles per hour is as follows:

12 hours ago: 1 km/hr = 0.621371 miles/hour

4 hours ago: 30 km/hr = 18.6411 miles/hour

1 hour ago: 100 km/hr = 62.1371 miles/hour

15 minutes ago: 350 km/hr = 217.479 miles/hour

6 minutes ago: 1000 km/hr = 621.371 miles/hour

3 minutes ago: 3000 km/hr = 1864.11 miles/hour

Now: 20,000 km/hr = 12427.4 miles/hour

The speed limit of 35 mph translates to approximately 56.327 km/hr. The car is currently exceeding the speed limit.

A single cell can either die, with probability .1, or split into two cells, with probability .9, producing a new generation of cells. Each cell in the new generation dies or splits into two cells independently with the same probabilities as the initial cell. Find the probability distribution for the number of cells in the next generation.

Answers

Final answer:

The probability distribution for the number of cells in the next generation is that there is a 0.1 probability of having zero cells if the original cell dies and a 0.9 probability of having two cells if the original cell splits and both daughter cells survive.

Explanation:

To find the probability distribution for the number of cells in the next generation, we analyze the outcomes of a single cell which can either die with a probability of 0.1 or split into two cells with a probability of 0.9. Since each cell behaves independently, we use the product rule of probability for each scenario.

There are two possible outcomes for a single cell:

The cell dies (probability 0.1)The cell splits into two cells (probability 0.9).

If the initial single cell splits, the next generation will consist of two cells. These two cells will then independently either die or split with the same probabilities as mentioned above. The probability distribution for the number of cells in the next generation is therefore:

Zero cells: This only happens if the initial cell dies, which has a probability of 0.1.One cell: This cannot happen because a cell either dies or splits into exactly two cells.Two cells: This occurs if the initial cell splits and neither of the two new cells dies, which has a probability of 0.9 (since we assume that the probability of both of the daughter cells surviving and splitting is included in the 0.9 probability).

Here, the sum of these probabilities adds to 1, meaning no other outcomes are possible within the scope of this single-generation model.

You talk to a friend who lives in a different state. She tells you that today it is 12° below zero where she lives. You tell her it is 54° where you live. What is the difference in temperatures?

Answers

friend = -12°C
you = -54°C

difference = 54 - 12
= 42 degrees.
12 degrees below zero tells you we have a negative number, -12. The word "Difference" means we are subtracting. So your equation will be 54 - (-12). Two minuses/negatives back-to-back turn into a plus so the equation is now 54 + 12 = 66.

There is a 66 degree difference in temperatures assuming the temperatures given are using the same units (I mean one is not Celsius and the other Fahrenheit).

Two factors are multiplied and their product it 34.44. One factor is a whole number. What is the least number of decimal places in the other factor. Explain.

Answers

The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.


*There are some cases where this doesn't apply, I think, but it does apply for your question.

The number of decimal places is the count of numbers after the decimal point in a decimal number. The least number of decimal places of the decimal factor is 2.

Let the factors be x and y; where:

[tex]x \to[/tex] whole number

[tex]y \to[/tex] number with decimal

The possible products that give 34.44 are represented as:

[tex]x \times y = 34.44[/tex]

So, we have:

[tex]2 \times 17.22 = 34.44[/tex]

[tex]3 \times 11.48 = 34.44[/tex]

[tex]4 \times 8.61 = 34.44[/tex]

[tex]5 \times 6.888 = 34.44[/tex]

[tex]6 \times 5.74 = 34.44[/tex]

And so on....

From the above computation, we have the decimal places of factors that represent y to be:

2 decimal places; i.e. numbers like 17.22, 11.483 decimal places; i.e. numbers like 6.888

By comparing the decimal places of these two factors, we can conclude that the least number of decimal places is 2.

A square pond is to be built in a park. The pond is 50 meters long and 50 meters wide. There should be a tile sidewalk 5 meters wide all around the pond. The tile is sold in crates of 45 square meters of tile. What will the tile cost if the cost of each box of tile is $74?

Answers

area of the pond is 50*50 = 2500 square meters

 the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters

 area of that is 60 *60 = 3600 meters

 area of walkway is 3600 - 2500 = 1100 square feet

number of crates needed: 1100 / 45 = 24.44, round up to 25 crates

25 crates x $74 each = $1,850 total

Convert "3/4 ton" into pounds.  Use the identity 2000 lb = 1 ton.
                                     2000 lb           1500 lb
Then       [(3/4) ton] * ---------------- = ----------------

Now divide 1500 lb by 4 lb 14 oz.  Note that 4 lb 14 oz = 4 14/16 lb, or
4 7/8 lb, or 4.875 lb.

Then, divide 1500 lb by

what is the structure of a poem

Answers

POETRY'S STRUCTURE AND FORM. POETRY'S RHYTHM. Rhythm gives a poem its sound, and there are many different ways that rhythm is used, and lots of elements in poetry that are related to rhythm. Stress / Accent A line of poetry is filled with syllables. When a syllable is given emphasis, it is called a stressed syllable.

Answer:

Poems are mostly written in lines and stanzas but it doesn't necessarily have a specific structure as such.

Explanation:

Structuring of a poem can be in multiple ways and there are no hard and fast rules. Though it is written in lines and stanzas, aside from that, there is no definite rule for writing a poem. Depending on the type of poem you are planning to write, it is required to try to follow the characteristics of the certain genre. For e.g, a sonnet is a fourteen line poem while an epic will deal with heroes, the free verse will be written in the author's own way, how long the lines will be or what shape it will take etc all depending on the writer. In short, the length of the line, the breaks, arrangement, rhythm or speed all depend on the content of the poem, and what it is about. Structure of a poem will all vary, depending on the type of poem written. So, to conclude, there is just no particular solution for writing a poem. It can be written in whatever way the writer wishes to, except that depending on the type of poetry s/he decides to write, it will have to follow the corresponding genre of that poetry.

the variable that makes sense to me would be approx.14.085, so 1.2r x 2 = approximately 33.8 if you round 14.085 to the nearest tenth.

For this question you need to calculate the fractions and understand the decimals or whole numbers (integers). When I was in middle school we always square rooted it, you can use your calculator if you like... but you can also divide the numerator by the denominator.. even though those are two different things, that's what my mathematics teacher taught us from a long time ago. That's my best advice, and then link it to the point. But you have to calculate each and everyone unless you know that fraction's decimal by heart.

Use the data set to answer the question. Correct value: 27 Data set: 19, 31, 22, 28, 24 Which best describes the data set?

Answers

Final answer:

The dataset shows moderate variability around a median of 24. The mean is 24.8, the mode is not available, and the range of the data is 12.

Explanation:

To describe the given data set: 19, 31, 22, 28, 24, we need to analyze several statistical measures including mean, median, mode, range, and possibly standard deviation.

First, let's calculate the mean which is the total sum of the data points divided by the number of points. Therefore, (19+31+22+28+24)/5 = 24.8

Next, the median is the middle term when the data is written in ascending order. In this case, 24 is the median as it is the middle value.

This data set has no repeating numbers hence there is no mode.

The range tells us the spread of the values, determined by subtracting the smallest value from the largest. Therefore, 31( largest) - 19(smallest) = 12.

Without further data, standard deviation is impractical to calculate. Based on the numbers we do have, this dataset appears to have somewhat moderate variability and a median value of 24.

Suppose the pattern 8, 16, 24, 32, ... is continued forever. Will the number 174 appear in the pattern? Why or why not?

Answers

no, because 32 * 2 = 64 and 64 * 2 = 128.
8 * 5 = 40
40 + 128 = 168
168 + 8 = 176

174 will not appear in the pattern 8, 16, 24, 32,

The given pattern 8, 16, 24, 32, ... is an arithmetic sequence where the first term (a) is 8 and the common difference (d) is 8.

We can use the formula for the nth term of an arithmetic sequence, which is:

an = a + (n-1)d

To find out if 174 is in the sequence, we set an to 174 and solve for n:

174 = 8 + (n-1)8

174 = 8 + 8n - 8
174 = 8n
n = 174 / 8
n = 21.75

Since n must be an integer for 174 to appear in the sequence, and 21.75 is not an integer, 174 will not appear in the pattern.
