To create the vectors using `seq()` and `rep()` in R:

(a) To create the vector `1;1:5;2;2:5;...;12`, we can use `seq()` and `rep()`. Here is the code:

```
vector_a <- c(1, rep(seq(1, 5), each = 2), seq(2, 5), 12)
```

- `seq(1, 5)` generates a sequence from 1 to 5.
- `rep(seq(1, 5), each = 2)` repeats each element of the sequence twice.
- `seq(2, 5)` generates a sequence from 2 to 5.
- `c()` combines all the elements into a vector.
- The resulting vector will be `1;1;2;2;3;3;4;4;5;5;2;3;4;5;12`.

The vector `1;1:5;2;2:5;...;12` can be created using `seq()` and `rep()` in R.

(b) To create the vector `1;8;27;64;...;1000`, we can use `seq()` and exponentiation (`^`). Here is the code:

```
vector_b <- seq(1, 1000) ^ 3
```
- `seq(1, 1000)` generates a sequence from 1 to 1000.
- `^ 3` raises each element of the sequence to the power of 3.
- The resulting vector will be `1;8;27;64;...;1000`, as each number is cubed.

The vector `1;8;27;64;...;1000` can be created using `seq()` and exponentiation (`^`) in R.

Answer

b

Step-by-step explanation:

Answer:

B) There is an error in step 2.

Step-by-step explanation:

When solving 8x+10-6x+4=24, you have to first combine your like terms. These are 8x and -6x (giving you 2x) and 10 and 4 (giving you 14).

After combing your like terms, you now have the equation 2x+14=24.

You need to get x alone and the first step to do that is to subtract 14 from both sides of the equation. This cancels out 14 from the side with x on it and leaves you with 10 on the other side. Your equation is now 2x=10

This is where the student made the mistake. Instead of subtracting 14, they added 14.

The final step would be to divide by 2 on both sides.

At the end of the problem, you are left with x=5.

No, Diego's estimation is not good because he overestimated the original value to nearly double the amount.

Overestimation is when we fix a value that is greater than the original value and underestimation when we fix a value that is less than the original value.

Given, Diego and his mom have been saving recycling items for months and today they traded them in they made 42 dollars on cans, 19 dollars on glass bottles, and 32 dollars on plastic bottles which are 83 dollars.

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

Probability is a mathematical study of outcomes in uncertain situation it is used to describe the like would have an event occurring and it can be expressed as the number between 0 to 1 probability is used to quantify the uncertainty associated with any given event it helps us understand how likely it is that something will happen and it can be used to make prediction about futures even probability theory is it of modern statistic and is widely used in fields such as finance economics and science.

Therefore, the probability of rolling at least one 3 when rolling two six-sided dice is 2 × 1/6, or 33.3%. This is because the probability of rolling a 3 on one die is independent of the probability of rolling a 3 on the other die. This means that the probability of rolling at least one 3 is equal to the sum of the probabilities of rolling a 3 on each of the two dice (1/6 + 1/6 = 2/6). As a result, the probability of rolling at least one 3 when rolling two six-sided dice is 33.3%.

The Answer for the question is (9<(2/x))

The probability of throwing a sum of 10 at least 3 times in 9 throws of a pair of fair dice is  approximately 0.3755 or about 37.55%.

To find the probability of throwing a sum of 10 at least 3 times in 9 throws of a pair of fair dice, we can use the binomial distribution. Let X be the number of times we throw a sum of 10 in 9 throws. Then X follows a binomial distribution with parameters n = 9 and p = 1/36, where p is the probability of throwing a sum of 10 in one throw.

The probability of throwing a sum of 10 exactly k times in 9 throws is given by the binomial probability mass function:

P(X = k) = (9 choose k) * p^k * (1-p)^(n-k)

where (9 choose k) is the binomial coefficient.

To find the probability of throwing a sum of 10 at least 3 times, we need to sum up the probabilities of throwing a sum of 10 exactly 3, 4, 5, 6, 7, 8, or 9 times:

P(X >= 3) = P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7) + P(X=8) + P(X=9)

P(X = k) = (9 choose k) * (1/36)^k * (35/36)^(9-k)

Using this formula, we can calculate each of the probabilities:

P(X=3) = (9 choose 3) * (1/36)^3 * (35/36)^6 ≈ 0.0004

P(X=4) = (9 choose 4) * (1/36)^4 * (35/36)^5 ≈ 0.0035

P(X=5) = (9 choose 5) * (1/36)^5 * (35/36)^4 ≈ 0.0165

P(X=6) = (9 choose 6) * (1/36)^6 * (35/36)^3 ≈ 0.0513

P(X=7) = (9 choose 7) * (1/36)^7 * (35/36)^2 ≈ 0.1142

P(X=8) = (9 choose 8) * (1/36)^8 * (35/36) ≈ 0.1750

P(X=9) = (9 choose 9) * (1/36)^9 * 1 ≈ 0.0146

Therefore, the probability of throwing a sum of 10 at least 3 times in 9 throws is:

P(X >= 3) = 0.0004 + 0.0035 + 0.0165 + 0.0513 + 0.1142 + 0.1750 + 0.0146 ≈ 0.3755

So the probability is approximately 0.3755 or about 37.55%.

The components of the vector from the point where the distress call was made to the point where the boat was found are 17.3 km east and 35.7 km south.

To determine the components of the vector from the point where the distress call was made to the point where the boat was found, we need to subtract the components of vector A from the components of vector B. Vector A is given as 45.0 km at 15.0° east of north, and vector B is given as 30.0 km at 15.0° north of east.

To find the x-component, we need to subtract the east component of vector A (45.0 km * cos(15.0°)) from the east component of vector B (30.0 km * sin(15.0°)). This gives us 17.3 km east.

To find the y-component, we need to subtract the north component of vector A (45.0 km * sin(15.0°)) from the south component of vector B (30.0 km * cos(15.0°)). This gives us 35.7 km south.

Therefore, the components of the vector from the point where the distress call was made to the point where the boat was found are 17.3 km east and 35.7 km south.

Answer:

9\(\sqrt{3}\) cm² or approximately 15.59 cm²

Step-by-step explanation:

Use the formula for the area of an equilateral triangle, A = \(\frac{\sqrt{3} }{4}\)a²

Plug in the side length, 6 cm, as a in the formula:

A = \(\frac{\sqrt{3} }{4}\)(6²)

A = \(\frac{\sqrt{3} }{4}\)(36)

A = 9\(\sqrt{3}\)

So, the area of the logo is 9\(\sqrt{3}\) cm² or approximately 15.59 cm²

Answer:

52 ft.

Step-by-step explanation:

there are 8 side that are 3 ft: 3×8=24

there are 4 sides that are 7 ft: 7×4=28

add it and you get: 24+28= 52

The area and perimeter of this shape are 133 ft² and 52 ft respectively.

Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.

Given that, a figure we need to find its perimeter and the area,

The figure we will be divided into 4 rectangles with sides 7 ft and 3 ft and a square, with side 7 ft

So, the area of the square = side²

= 7² ft²

= 49 ft²

Now, the area of a rectangle = length x width = 4 x 3 x 7 [since there are 4 rectangles]

= 4 x 3 x 7 = 84 ft²

The whole area = 84 + 49 = 133 ft²

Now, the perimeter = sum of the sides = 7 x 4 + 3 x 8 = 28 + 24 = 52 ft

Hence, the area and perimeter of this shape are 133 ft² and 52 ft respectively.
