The sequence of arithmetic sequence be 37, 29, 21, 13 then the 52nd term exists 445.

The term "arithmetic sequence" refers to an ordered collection of numbers with a common difference between each succeeding word.

Arithmetic sequences are those that contain these patterns. The difference between successive terms in an arithmetic series is constant.

An arithmetic sequence, also known as an arithmetic progression, is a set of numbers where each term differs from the one before it. The arithmetic sequence formula makes it simple to determine a term's value and the sequence's common difference.

The AP's first period is 37.

Common difference = 37 - 29 = 29 - 21 = 8.

Let the equation of arithmetic sequence be a + ( n - 1 )d, where d is the common difference and a is the first term.

To find the 52nd term, we get

substitute the values in the above equation, we get

⇒ 37 + ( 52 - 1 )8

simplifying the above equation, we get

⇒ 37 + ( 51 )8

⇒ 37 + 408

⇒ 445

Therefore, the 52nd term of the arithmetic sequence exists 445.

Answer:

See below

Step-by-step explanation:

This is a system of equations. That means you are trying to find the point that makes both lines true at the same time.

To do this you have to solve for one variable at a time. Luckily, these equations already have one variable that will cancel. If you add 2x and -2x, you get 0. I'm going to line these up like a vertical math problem to show you how it works.

-2x + 3y = 12

2x +3y = 0                    Add together

-------------------

0x + 6y = 12                Simplify by removing the 0x

6y =12                        Divide both sides by 6 to solve for y

y = 2

Plug 2 in for y in one of the original equations.

2x + 3(2) = 0

2x + 6 = 0                   Subtract 6 from both sides

2x = -6                        Divide by 2 to solve for x

x = -3

The point that makes both lines true is (-3,2). This is where the lines intersect.

Therefore, the difference in mass between Earth and Venus is approximately 5.96513 x 10^24 kilograms.

The difference in mass between Earth and Venus is:

5.97 x 10^24 kg - 4.87 x 10^12 kg

To subtract these two values, we need to express them in the same scientific notation. Since 4.87 x 10^12 is much smaller than 5.97 x 10^24, we can express it in scientific notation with the same exponent as the mass of Earth:

4.87 x 10^12 kg = 0.00487 x 10^24 kg

Now we can subtract the two values:

5.97 x 10^24 kg - 0.00487 x 10^24 kg = 5.96513 x 10^24 kg

Therefore, the difference in mass between Earth and Venus is approximately 5.96513 x 10^24 kilograms.

4                                              A
5                                              7

The frequency is how many people have the shoe sizes. For example, 11 people have shoe size 3, and 7 people have shoe size 5. Since 30 people's shoe sizes were recorded, 30 - (11+7) will be the answer.

30 will be from the 30 people whos shoe sizes were recorded. The 11 will be from the people with shoe size 3, and the 7 will be from the people with shoe size 5. So, 30 - 18 = 12.

12 people have shoe size 4.

The three values (60, 62, and 84) are identified as outliers for the age group 40 years to 50 years is D. Only 60 and 84 are identified as outliers

we need to use the same method as for the age group 20 years to 30 years.

The interquartile range (IQR) for the age group 40 years to 50 years is calculated as follows:

Q3 - Q1 = 76 - 70 = 6

To identify outliers, we consider values that are either 1.5 times the IQR greater than the upper quartile (Q3 + 1.5 * IQR) or 1.5 times the IQR less than the lower quartile (Q1 - 1.5 * IQR).

For the age group 40 years to 50 years:

Upper limit = Q3 + 1.5 * IQR = 76 + 1.5 * 6 = 85

Lower limit = Q1 - 1.5 * IQR = 70 - 1.5 * 6 = 61

Now let's compare these limits with the three values:

60 is less than the lower limit (61), so it is considered an outlier.

62 is between the lower and upper limits, so it is not considered an outlier.

84 is greater than the upper limit (85), so it is considered an outlier.

Therefore, the values identified as outliers for the age group 40 years to 50 years are 60 and 84. The value 62 is not considered an outlier.

The correct answer is (D) Only 60 and 84 are identified as outliers.

By applying the same method of identifying outliers based on the 1.5 times IQR rule, we can determine which values fall outside the acceptable range for each age group. Therefore, Option D is correct

As a result, both the event of choosing a child with blue eyes and the event of choosing a left-handed individual may happen at the same time.

Probability is a metric for determining the probability or chance that a specific event will take place. It is represented by a number between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty. The likelihood of flipping a coin and receiving heads, for instance, is 0.5 because there are two possible results (heads or tails), and each has an equal likelihood of happening. Similar to this, there are six potential outcomes on a six-sided die, but only one of them is a 4, so the likelihood of rolling a 4 is 1/6.

given

a) Because a die roll can produce either an even number or an odd number, but not both, the occurrences are mutually exclusive.

Therefore, it is impossible for the events of rolling a 6 and an unusual number to happen at the same time.

The exact value of cosθ in simplest form is cosθ = -2√3/7.

The answer is cosθ = -2√3/7.

Given that sinθ = -√13/7 and angle θ is in Quadrant III, we can determine that cosθ is negative in Quadrant III. Using the Pythagorean identity sin²θ + cos²θ = 1, we can solve for cosθ. Since sinθ = -√13/7, we have (-√13/7)² + cos²θ = 1. Simplifying, 13/49 + cos²θ = 1, and rearranging, we find cos²θ = 36/49. Taking the square root of both sides, we have cosθ = ±6/7. Since cosθ is negative in Quadrant III, the exact value of cosθ in simplest form is cosθ = -6/7. Simplifying further, we get cosθ = -2√3/7.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The total number of games the team played last year was 80 (option C). In the first half of the year, the team won 60 percent of their games, indicating that they won 6 out of every 10 games played.

In the second half of the year, the team played 20 games and won 3 of them. This means that in the second half, they won only 3 out of 20 games, which is equivalent to winning 15 percent of their games.

To find the overall percentage of games won, we can calculate the weighted average of the two percentages. Since the team won 50 percent of their games overall, we can assign equal weights to the first and second halves of the year. Therefore, the average winning percentage for the team would be the midpoint between 60 percent and 15 percent, which is (60% + 15%) / 2 = 37.5%.

Let's assume the total number of games played last year was x. Since the team won 37.5% of the games, they won 0.375x games. We can set up an equation based on the information given:

0.375x = 50% of x

0.375x = 0.5x

0.5x - 0.375x = 0

0.125x = 0

x = 0 / 0.125
