Answer:

Step-by-step explanation:

In the early 1940s, the Nazi regime had taken over most of Europe and began to implement their "Final Solution" plan, which aimed to exterminate all Jews and other minority groups from the continent. As a result, many people were forced into concentration camps, where they were subjected to terrible living conditions and constant fear of death.

One of these people was a young girl named Anne Frank, who lived in hiding with her family in Amsterdam. She chronicled her experiences in a diary, which has since become one of the most famous accounts of the Holocaust.

Despite the constant danger and fear, many people managed to survive the Holocaust through acts of bravery and resistance. One such person was Oskar Schindler, a German industrialist who saved the lives of over 1,000 Jewish workers by employing them in his factory.

Other survivors included the "Righteous Among the Nations," non-Jewish individuals who risked their lives to help Jews escape persecution. Among them were Irena Sendler, who smuggled over 2,500 Jewish children out of the Warsaw ghetto, and Raoul Wallenberg, who issued protective passports to Jews in Hungary.

The Holocaust was a dark period in human history, but the bravery and resilience of those who survived serves as a reminder of the power of hope and humanity in even the darkest of times.

The probability of getting a sum of 7 is 6/36, which simplifies to 1/6 or approximately 16.67%.

Here's a step-by-step explanation using the terms die, sum, spots, and drawing:

1. Die: A standard die has 6 faces with spots numbered 1 to 6.
2. Rolling the die 2 times: You roll the die once, record the number of spots, then roll it again.
3. Sum of the spots: Add the number of spots from the first roll to the number of spots from the second roll.
4. Drawing: A drawing can be a table or a chart to represent the possible outcomes and their corresponding sums.

To visualize this, you can create a 6x6 drawing (table) with rows and columns representing the spots on each roll:

```
  1  2  3  4  5  6
1  2  3  4  5  6  7
2  3  4  5  6  7  8
3  4  5  6  7  8  9
4  5  6  7  8  9 10
5  6  7  8  9 10 11
6  7  8  9 10 11 12
```

This drawing shows all possible sums (from 2 to 12) when rolling a die two times. To find the probability of a specific sum, count the number of times that sum appears in the table, and divide it by the total number of outcomes (6 x 6 = 36).

Answer:

87.96

Step-by-step explanation:

Where pi is approximately equal to 3.14 and r is the radius of the circle.

In this case, the radius is 14 yards.

So the circumference is:

2pi14 = 87.96 yards.

Answer:

[tex]A= \frac{18769}{4 \pi}[/tex]

Step-by-step explanation:

The formula for the circumference of a circle is [tex]C=2\pi r[/tex], where C is the circumference and r is the radius. The formula for the area of a circle is [tex]A=\pi r^2[/tex], where A is the area and r is the radius. To find the area, we need to find the radius.

Since we know the circumference but not the radius, we set up the circumference formula with r as the unknown: [tex]137=2\pi x[/tex]. We divide [tex]2 \pi\\[/tex] into both sides to get the radius: [tex]x=\frac{137}{2 \pi}[/tex]. (We leave pi, as it is asking in terms of pi).

Now, we plug the radius into the formula for area: [tex]A= \pi (\frac{137}{2 \pi})^2[/tex]. First, we double the radius:  [tex]A= \pi \frac{18769}{4 \pi ^2}[/tex] and then we simplify the right side of the equation again by multiplying: [tex]A= \frac{18769 \pi }{4 \pi ^2}[/tex]. Then, we cancel out pi on both sides to finally get the area: [tex]A= \frac{18769}{4 \pi}[/tex].

(a) For 10 kWh, we use the first function because 0 ≤ 10. So, C(10) = 7.52 + 0.1079(10) = $8.60.
(b) For 27 kWh, we use the second function because 10 < 27 ≤ 750. So, C(27) = 19.22 + 0.1079(27) = $22.45.
(c) For 9000 kWh, we use the fourth function because 9000 > 1500. So, C(9000) = 131.345 + 0.0321(9000) = $425.25.

In mathematics, a function from the set X to the set Y assigns each element of X to one of Y. The set X is called the function of the function, and the set Y is called the common area of ​​the function.

A function is basically a measure of how one variable depends on another variable. For example, the earth's position is a function of time. Historically, the concept was explained using infinitesimal calculus in the late 17th century, and until the 19th century, functions were determined differently (i.e. they had a higher regularity).

(a) For 10 kWh usage, we use the first formula since 0 ≤ x ≤ 10:
C(10) = 7.52 + 0.1079(10) = 7.52 + 1.079 = $8.60 (rounded to the nearest cent)

(b) For 27 kWh usage, we use the second formula since 10 < x ≤ 750:
C(27) = 19.22 + 0.1079(27) = 19.22 + 2.9133 = $22.13 (rounded to the nearest cent)

(c) For 9000 kWh usage, we use the fourth formula since x > 1500:
C(9000) = 131.345 + 0.0321(9000) = 131.345 + 288.9 = $420.24 (rounded to the nearest cent)

So, the monthly charges for the given usages are:
(a) 10 kWh: $8.60
(b) 27 kWh: $22.13
(c) 9000 kWh: $420.24

Answer:

(-1/6, -7/12)

Step-by-step explanation:

From the second equation, we get:

2y = x - 1

y = (1/2)x - 1/2

Substituting for y in the first equation, we get:

7x - 2(1/2)x + 1 = 0

7x - x + 1 = 0

6x + 1 = 0

6x = -1

x = -1/6

Substituting back into the second equation to find y:

2y = (-1/6) - 1

2y = -7/6

y = -7/12

Therefore, the solution is (-1/6, -7/12).

To check, we substitute these values into both equations:

7(-1/6) - 2(-7/12) = 1

-7/6 + 7/6 = 1

1 = 1

This is true, so our solution is correct.

The probability that William is the first to throw a 6 is approximately 125/1296 or roughly 0.096.

You asked for the probability that William is the first to throw a 6 when Nicola, Stephanie, Kathryn, and William take turns rolling a fair die.

To calculate this probability, we need to consider the following events:
1. William rolls a 6.
2. Nicola, Stephanie, and Kathryn all roll a number other than 6.

The probability of each person rolling a 6 is 1/6, while the probability of not rolling a 6 is 5/6.

So, the probability that William is the first to roll a 6 is:

P(William rolls 6) = P(Nicola rolls not 6) × P(Stephanie rolls not 6) × P(Kathryn rolls not 6) × P(William rolls 6)
= (5/6) × (5/6) × (5/6) × (1/6)

Now, multiply the fractions:

= (5 × 5 × 5 × 1) / (6 × 6 × 6 × 6)
= 125 / 1296

So, the probability that William is the first to throw a 6 is approximately 125/1296, or roughly 0.096 (rounded to 3 decimal places).

To calculate the probability that the mean play time in a random sample of 100 songs is less than 240 seconds, we need to know the population mean and standard deviation. Let's assume that the population mean is 250 seconds and the standard deviation is 30 seconds.

Using the central limit theorem, we can assume that the distribution of the sample means follows a normal distribution with a mean of 250 seconds and a standard deviation of 30/√(100) = 3 seconds.

To find the probability that the mean play time in a random sample of 100 songs is less than 240 seconds, we need to standardize the value using the formula:

Z = (X - μ) / (σ / √(n))

where X is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Plugging in the values, we get:

Z = (240 - 250) / (3)

Z = -3.33

Using a standard normal distribution table or calculator, we can find the probability of Z being less than -3.33 is approximately 0.0004.

Therefore, the probability that the mean play time in a random sample of 100 songs is less than 240 seconds is 0.0004 (rounded to 4 decimal places).

Using triangle proportionality AB/AD is proportional to BC/CD. Using the isosceles triangle in the construction EC = EB.

These lead to the proportion that corresponds to the angle bisector theorem of AB/AD = AC/CD.

The angle bisector theorem states that the angle bisector of a triangle divides the opposite side into segments that are proportional to the other two sides of the triangle. This theorem can be proven using triangle similarity and the concept of proportionality.

Let ABC be a triangle with angle bisector AD, where D lies on BC. To show that AB/BD = AC/CD.

First, use the fact that triangles ABD and ACD are similar by angle-angle-angle similarity, since they share two congruent angles (angle A and angle BAD is congruent to angle CAD by the angle bisector theorem). Therefore:

AB/AD = BD/CD (by the definition of similar triangles)

Cross-multiplying gives:

AB × CD = AD × BD

Similarly, use the fact that triangles ABC and ABD are similar:

AB/AC = BD/CD

Cross-multiplying gives:

AB × CD = AC × BD

Combining these two equations:

AB × CD = AD × BD = AC × BD

Dividing both sides by BD gives:

AB/BD = AC/CD

Therefore, the angle bisector theorem is proven.

The formula 5 of the theorem states:

d/dt (u(t) x v(t)) = (d/dt u(t)) x v(t) + u(t) x (d/dt v(t))

where x denotes the cross product.

First, we need to find the derivatives of u(t) and v(t):

d/dt u(t) = (9 cos(9t), -9 sin(9t), 1)

d/dt v(t) = (1, -9 sin(9t), 9 cos(9t))

Now we can substitute into the formula:

d/dt (u(t) x v(t)) = (9 cos(9t), -9 sin(9t), 1) x (t, cos(9t), sin(9t)) + (sin(9t), cos(9t), t) x (1, -9 sin(9t), 9 cos(9t))

Expanding the cross products, we get:

d/dt (u(t) x v(t)) = (-9 sin(9t), -9t cos(9t), 81 cos(9t)) + (9 cos(9t), -t sin(9t), -9 sin(9t))

Simplifying, we get:

d/dt (u(t) x v(t)) = (0, -t cos(9t) + 72 sin(9t), 81 cos(9t) - 9t sin(9t))

B.

a) Since xi>1, we can subtract 2 from each xi, which gives us the equation x1' + x2' + x3' + x4' + x5' + x6' = 17, where xi' = xi - 2. Then, we can use stars and bars to get the solution as (17 + 6 - 1)C(6 - 1) = 22C5.

b) Since x2>1, x5>5, and x6>0, we can subtract 2 from x2, subtract 6 from x5, and subtract 1 from x6, which gives us the equation x1 + x2' + x3 + x4 + x5' + x6' = 20, where xi' = xi - 2 for i = 2, 5, and xi' = xi - 1 for i = 6. Then, we can use stars and bars to get the solution as (20 + 6 - 1)C(6 - 1) = 29C5.

c) Since x3≥5, we can subtract 5 from x3, which gives us the equation x1 + x2 + x3' + x4 + x5 + x6 = 24, where x3' = x3 - 5. Then, we can use stars and bars to get the solution as (24 + 6 - 1)C(6 - 1) = 23C5.

d) To find the number of solutions where xi<8 for all i and xi>8 for at least one i, we can subtract 1 from x5, which gives us the equation x1 + x2 + x3 + x4 + x5' + x6 = 21, where x5' = x5 - 1. Then, we can use stars and bars to get the total number of solutions where xi<8 for all i as (21 + 6 - 1)C(6 - 1) = 26C5. To find the number of solutions where xi<8 for all i and xi>8 for at least one i, we can subtract 9 from xi for the i that is greater than 8 and subtract 1 from x5, which gives us the equation x1 + x2 + x3 + x4 + x5' + x6' = 12, where x5' = x5 - 1 and x_i' = x_i - 9 for i>8. Then, we can use stars and bars to get the total number of solutions where xi<8 for all i as (12 + 6 - 1)C(6 - 1) = 16C5. Therefore, the number of solutions where xi<8 for all i except xi>8 for at least one i is 26C5 - 16C5 = 6C122C5 - 1 - 6C114C5.

dy/dt (t=1) = 3/(2 * [tex]\sqrt{(3(1) + 1)}[/tex]) = 3/4
5. Calculate dy/dx at t = 1:
dy/dx = (3/4) / 2 = 3/8
So, the answer is 3/8.

The interval for diameters of acceptable washers is 2.78 cm ≤ d ≤ 2.92 cm.

Using the given formula, C = 3.14d, we can solve for the diameter range that corresponds to the acceptable circumference interval of 8.8 cm ≤ C ≤ 9.2 cm.

First, we can divide both sides of the formula by 3.14 to get d = C/3.14. Then, we substitute the values for the acceptable interval of C to get:

8.8/3.14 ≤ d ≤ 9.2/3.14

Simplifying this compound inequality, we get:

2.795 ≤ d ≤ 2.923

Rounding to two decimal places, the interval for diameters of acceptable washers is 2.78 cm ≤ d ≤ 2.92 cm. Therefore, any washer with a diameter within this range will have an acceptable circumference according to Company A's standards.

the set of points at which the function G(x, y) = ln(1+x−y) is continuous is the set of all (x, y) such that y < x+1.

To determine the set of points at which the function G(x, y) = ln(1+x−y) is continuous, we need to check for continuity in both x and y directions.

First, we consider the x-direction. The function ln(1+x−y) is continuous for all x and y such that 1+x−y > 0, i.e., x−y > −1. Therefore, the set of points at which the function is continuous in the x-direction is the set of all (x, y) such that x−y > −1.

Next, we consider the y-direction. The function ln(1+x−y) is continuous for all x and y such that 1+x−y > 0, i.e., x > y−1. Therefore, the set of points at which the function is continuous in the y-direction is the set of all (x, y) such that x > y−1.

To determine the overall set of points at which the function is continuous, we need to find the intersection of the sets of points where the function is continuous in the x and y directions.

The set of all (x, y) such that x−y > −1 is equivalent to the set of all (x, y) such that y < x+1.

The set of all (x, y) such that x > y−1 is equivalent to the set of all (x, y) such that y < x+1.

Therefore, the set of points at which the function G(x, y) = ln(1+x−y) is continuous is the set of all (x, y) such that y < x+1.

Answer: 720 miles

Step-by-step explanation:

180/3= 60 which means she drove 60 miles in 1 hour. so 60 x 12 = 720 miles

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}- the sum of the dots ranges from 2 to 12

S = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}  - the minimum sum is 2.

S = {2, 4, 6, 8, 10, 12} - even sums

S = {1, 3, 5, 7, 11} - odd sums

I understand you want an explanation of the different sets in the context of rolling a pair of dice and recording the sum of the dots on the two faces that come up. Let me break it down for you:

1. When a pair of dice is rolled, the possible sum of the dots ranges from 2 (both dice showing 1) to 12 (both dice showing 6). This range is represented by the first set: S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

2. The second set, S = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}, represents all the possible sums excluding the sum of 1, which is actually not possible when rolling a pair of dice, as the minimum sum is 2.

3. The third set, S = {2, 4, 6, 8, 10, 12}, represents all the even sums that can be obtained when rolling a pair of dice.

4. The last set, S = {1, 3, 5, 7, 11}, represents all the odd sums that can be obtained when rolling a pair of dice, with the exception of 1 and 9. However, as mentioned before, 1 is not a possible sum, and 9 should be included in the set to accurately represent all odd sums.

In summary, these sets represent different subsets of possible sums when a pair of dice are rolled and the sum of the dots on the two faces is recorded.

We cannot solve for this probability without more information.

If Alana and Eva assume that x and y are independent, then the probability of x=1 and y=2 is simply the product of their individual probabilities. Thus, P(x=1) = the probability of x being equal to 1, regardless of the value of y. We do not have enough information to determine this probability, so we cannot give a specific answer.

Similarly, P(y=2) = the probability of y being equal to 2, regardless of the value of x. Again, we do not have enough information to determine this probability, so we cannot give a specific answer. However, we do know that the joint probability of x=1 and y=2 is given by P(x=1, y=2) = P(x=1) * P(y=2) due to the assumption of independence. Unfortunately, we cannot solve for this probability without more information.
