The probability of a diffusing atom jumping from one site to another is influenced by temperature. It is typically described by the Arrhenius equation:

P = \(Ae^{(-Q/RT)}\)

Where:

P is the probability of a jump

A is the pre-exponential factor

Q is the activation energy

R is the gas constant

T is the absolute temperature in Kelvin

To calculate the probability at 500°C and 1000°C, we need to convert these temperatures to Kelvin:

\(T_{500C}\) = 500 + 273.15

= 773.15 K

\(T_{1000C}\) = 1000 + 273.15

= 1273.15 K

Assuming we have values for the pre-exponential factor (A) and activation energy (Q), we can substitute these values into the Arrhenius equation to calculate the probabilities at the given temperatures. However, without specific values for A and Q, we cannot provide a numerical answer.

Answer:

You probably already figured it out, but the correct answer is the last one. Subtract 3 from the product of 9 and m

Step-by-step explanation:

Reason for this is 9m is the same as 9 multiplied by m, or the product of 9 and m. You always do multiplication before subtracting or adding, therefore you are subtracting 3 FROM the product of 9 and m

The scale factor is 4 after applying the concept of the similar triangle, option (A) 8/2 = 4/1 = 4 is correct.

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that:

The two similar triangles are shown in the picture.

The base length of the triangle b = 8

The height of the triangle b = 4

The base length of the triangle a = 2

The height of the triangle a = 1

The ratios of the corresponding sides:

Scale factor = 8/2 = 4/1 = 4

Thus, the scale factor is 4 after applying the concept of the similar triangle, option (A) 8/2 = 4/1 = 4 is correct.

To create a stemplot, we first need to separate the data into "stems" and "leaves." Each stem represents the first digit(s) of each data point, while each leaf represents the last digit(s). For example, if the data point is 12.3, the stem would be 12 and the leaf would be 3.

To make a stemplot, the data should be arranged in increasing order, and then separated into stems and leaves.

However, you can use the data given and arrange it in increasing order and separate it into stems and leaves to make a stemplot. A stemplot is a good way to check if the data follow a normal distribution quite closely, the more the data is spread out and the more symmetric it is, the more likely it is to follow a normal distribution.

Also, it is important to mention that from the given data, it is not possible to conclude if the percent change in this population has standard deviation of 2.5%. This parameter can only be estimated from a sample if it follows a normal distribution which is not clear from the given data.

Answer:

9, 23, 45, 75, 113, 159

Step-by-step explanation:

Quadratic Sequence

The difference between two consecutive terms of a quadratic sequence is another sequence, this one is an arithmetic sequence.

The first terms are given as:

9, 23, 45, 75, ...

Let's compute the differences:

23 -  9  = 14

45 - 23 = 22

75 - 45 = 30

Note the differences form an aritmetic sequence of commons difference 8.

The next two terms will be formed adding 8 to the previous difference, that is:

30 + 8 = 38 is the next difference. And the next term is

75 + 38 = 113

38 + 8 = 46 is the next difference, and the next term is

113 + 46 = 159

Thus, the complete sequence is

9, 23, 45, 75, 113, 159

Answer:

183 cm^2

Step-by-step explanation:

the line through the shape line means that they are equivalent meaning the side that is empty not making the trapezoid would be 9 as well. moving the 3 over since it is right next to it. 3 times 9 equal 27cm^2. later we are gonna use this number to subtract

then make a different equation with 3+9 to the the full height of the trapezoid pretending it is not missing anything. 3+9=12

then use the formula to find the area of the trapezoid which is 1/2(h)(b1+b2)

add the 2 bases together to get 35. how did i get 35. 12+14=26 yes then include the 9 to get 35.

1/2(height=12)(35)=6(35)=210cm^2

then you used 210-27 to get 183cm^2

A percentage is a way to describe a part of a whole. The regular selling price of the computer notebook will be $937.5.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Let the selling price of the computer notebook be represented by x.

Now, if Sara buys the computer this week, the selling price of the computer will be (100%-16%)x = 0.84x.

Also, the saving she made by buying this week will be $150, therefore, we can write,

x-0.84x = $150

0.16x = $150

x = 937.5

The equation representing the graph as shown in the figure is y =

- 5.01x³ + 36.02x

The degree of a cubic polynomial is three.

Given is the general cubic equation as -

ax³ + bx² + cx + d

Now, the graph shows that the equation of this cubic equation passing through 3 points as -

(- 6, 0) , (2, 32) , (6, 0)

This means that these coordinates will satisfy the equation ax³ + bx² + cx + d = y.

Therefore -

For x = - 6 :

a(-6)³ + b(-6)² - 6c + 0 = 0

- 216a + 36b - 6c = 0            .. [1]

For x = 2 :

8a + 4b + 2c + 0 = 32          .. [2]

For x = 6 :

a(6)³ + b(6)² - 6c + 0 = 0

216a + 36b + 6c  + 0 = 0        .. [3]

Adding Eq[1] and Eq[3], we get -

- 216a + 36b - 6c + 216a + 36b + 6c = 0

72b = 0

b = 0

Then equation [2] will become -

8a + 2c = 32

4a + c = 16                 .. [4]

Subtracting Eq[1] and Eq[3], we get -

216a + 36b + 6c - (- 216a + 36b - 6c) = 0

216a + 36b + 6c + 216a - 36b + 6c = 0

432a + 12c = 0              .. [5]

Multiply [4] by 12, we get -

48a + 12c = 1922     .. [6]

Subtracting Eq[6] and Eq[5], we get -

432a + 12c - 48a - 12c = - 1922

384a = - 1922

a = - 5.01

Then -

4 x - 5.01 + c = 16

c = 16 + 20.02

c = 36.02

So -

[a] = - 5.01

[b] = 0

[c] = 36.02

[d] = 0

Therefore, the equation representing the graph as shown in the figure is y = - 5.01x³ + 36.02x

By the calculations below, there are 20 groups of 1/5 in 4.

To find out how many groups of 1/5 are in 4, we can use the concept of division of fractions.

Recall that dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the problem as:

4 ÷ 1/5

To find the reciprocal of 1/5, we flip the fraction:

1/5 → 5/1

Now, we can rewrite the division problem as multiplication:

4 ÷ 1/5 = 4 × 5/1

Multiplying across gives:

4 × 5/1 = 20

The equation x = z represents a line in three-dimensional space that passes through the origin and has a slope of 1.

The equation x = z represents a line in three-dimensional space. In this case, the line is a diagonal line that extends infinitely in both the positive and negative directions. It passes through the origin (0, 0, 0) and has a slope of 1.

To understand this visually, imagine a coordinate system with x, y, and z axes. The line x = z can be represented by points such as (1, 0, 1), (-2, 0, -2), (3, 0, 3), and so on. These points all lie on the line where the x and z coordinates are equal.

You can also think of this equation as saying that the x-coordinate of a point is always equal to its z-coordinate. So if you have a point like (2, 0, 2), the x and z coordinates are equal, satisfying the equation x = z.

In terms of the region represented by this equation, it's a straight line that extends infinitely in both the positive and negative directions in the x-z plane. All points on this line have the property that their x and z coordinates are equal.

The equation x = z represents a line in a three-dimensional coordinate system.

The equation x = z represents a line in a three-dimensional coordinate system. In this equation, the x-coordinate is always equal to the z-coordinate. This means that for any point on the line, the x-coordinate and the z-coordinate have the same value.

To understand this visually, imagine a three-dimensional coordinate system with x, y, and z axes. When x = z, it means that the points on the line have the same x and z values, while the y-coordinate can take any value. This line extends infinitely in both the positive and negative directions along the x and z axes.

For example, if we take the point (1, 2, 1) on this line, we can see that the x-coordinate (1) is equal to the z-coordinate (1). Similarly, if we take the point (-2, 5, -2), the x-coordinate (-2) is equal to the z-coordinate (-2).

In conclusion, the equation x = z represents a line in a three-dimensional coordinate system where the x-coordinate is always equal to the z-coordinate.

The correct answer is $21.16

Explanation:

The first step to solve this mathematical problem and find the correct answer is to calculate the cost of the sales tax and the tip by using the cost of the meal. The process is shown below:

1. Calculate the sales tax (7%)

7% of $65.92

65.92 / 100 = 0.6592

0.6592 x 7 = 4.6144 (Money on the sales tax)

2. Now, add the initial cost of the meal to the taxes and calculate the tip (20%)

$65.92 + $4.6144 = $70.5344

20% of $70.5344

70.5344 / 100 = 0.705344

0.705344 x 20 = 14.10688 (Money on tip)

Now, let's add the three values to calculate the total cost of the meal

$65.92 + $4.6144 + $14.10688 = $84.64128

Finally, divide the price into 4 because 4 people will pay
