To find the average rate of change of \(\(f(x)\) from \(x_1 = -4\) to \(x_2 = -2\)\) , we need to calculate the difference in function values and divide it by the difference in x-values.

Given that \(\(f(x) = 2x + 9\)\), let's calculate the average rate of change:

Average rate of change = \(\(\frac{f(x_2) - f(x_1)}{x_2 - x_1}\)\)

Substituting the given values:

Average rate of change = \(\(\frac{f(-2) - f(-4)}{-2 - (-4)}\)\)

Evaluate the function at the given x-values:

\(\(f(-2) = 2(-2) + 9 = 5\)\)

\(\(f(-4) = 2(-4) + 9 = 1\)\)

Substitute the function values into the formula:

Average rate of change = \(\(\frac{5 - 1}{-2 - (-4)}\)\)

Simplifying:

Average rate of change = \(\(\frac{4}{-2 + 4} = \frac{4}{2} = 2\)\)

Therefore, the average rate of change of \(\(f(x)\)\) from \(\(x_1 = -4\) to \(x_2 = -2\) is 2.\)

The Probability that a randomly selected student who performed in the spring play, but did not perform in the spring concert is chosen is 26/53.

Now let A be the event of the student performing in Spring play

Let B be the event of students performing i the spring concert

Now according to what we know,

n(A) = 68

n(B) = 54

n(A ∩ B) = 16

Now total no. of students will be n(A U B) = 68 + 54 - 16

= 106

We need to find the number of people who performed in the spring play and not in the concert

Hence we need to find the Probability

P(A ∩ not B)

Now we can say that (A ∩ not B) will clearly be

A - (A ∩ B) Hence we get it to be

Step-by-step explanation:

Using the conversion

1 Kg = 1000g, then

650g = 650 ÷ 1000 = 0.65 Kg

Thus the cost of 650g = 0.65 × £9.20 = £5.98

Answer:

13

Step-by-step explanation:

Prime numbers are only divisible by 1 or themselves.

No other factors

The probability that a student is left-handed is 13%, so the probability that a student is right-handed is 87%.

Out of 200 seats, 30 are designed for left-handers. Therefore, the number of seats designed for right-handers is 200 - 30 = 170.

If a class has 188 students, and 13% of them are left-handed, then the number of left-handed students is 188 * 0.13 = 24.44, which we can round up to 25.

This means that the number of right-handed students in the class is 188 - 25 = 163.

The probability that a right-handed student is forced to use a lefty arm tablet is equal to the probability that there are no more right-handed seats available when they arrive.

The probability that the first student who arrives is right-handed and gets a right-handed seat is 170/200 = 0.85.

If a right-handed student takes a right-handed seat, then there are 169 right-handed seats left out of 199 total seats remaining.

The probability that the second student who arrives is also right-handed and gets a right-handed seat is 169/199.

Continuing in this way, the probability that all 163 right-handed students get right-handed seats is:

(170/200) * (169/199) * (168/198) * ... * (8/38) * (7/37) * (6/36)

The probability that at least one right-handed student is forced to use a lefty arm tablet is equal to 1 minus the probability that all 163 right-handed students get right-handed seats:

1 - [(170/200) * (169/199) * (168/198) * ... * (8/38) * (7/37) * (6/36)]

Using a calculator, we find that this probability is approximately 0.358 or 35.8%.

Answer:

One Solutions I think

Step-by-step explanation:

Given the set of values, you have to determine the y-intercept, slope, and the equation that corresponds to de relationship on the table.

The slope-intercept form is

Where

m represents the slope

b represents the y-intercept (is the y-coordinate of the point corresponding to the y-intercept)

The y-intercept of any function in the coordinate system is the point where the line intercepts the y-axis, at this point the x-coordinate is equal to zero. You can determine this value directly from the table, the ordered pair (0,6) corresponds to the y-intercept coordinates.

So "b = 6"

To determine the slope of the line, m, you need to use two points of the line and the following formula:

Where

(x₁,y₁) are the coordinates of one point on the line

(x₂,y₂) are the coordinates of a second point on the line

You can use any two points of the line to calculate the slope, I will use (2,14) and (1,10)

The slope of the line is m=4

Finally, you have to replace the values of the slope and y-intercept in the formula to determine the equation of the line in slope-intercept form:

For b=6 and m=4

The value of the first term that is less than 0 is -4

The formula for the nth term of an arithmetic sequence is:

aₙ = a₁ + (n - 1)d

Where a₁ is the first term in the sequence, d is the common difference between terms, and n is the position of the term that we are trying to find.

If in an arithmetic sequence, the first term is 100 and the fourth term is 76, then the common difference is

aₙ = a₁ + (n - 1)d

76 = 100 + (4 - 1)d

76 = 100 + 3d

3d = 76 - 100

3d = -24

d = -8

Solve for aₙ that is less than 0.

aₙ = a₁ + (n - 1)d

aₙ = 100 + (n - 1)(-8) < 0

100 - 8n + 8 < 0

8n > 108

n > 13.5

a₁₄ = 100 + (14 - 1)(-8) = -4

Therefore, the value of the first term that is less than 0 is -4.

To determine the value of the standard normal random variable z for which the area to the right of z is 0.2643, we can use the standard normal distribution table or a statistical software.

The value of z corresponding to an area to the right of z can be obtained by subtracting the given area from 1 since the area to the right is complementary to the area to the left. Therefore, the area to the left of z would be 1 - 0.2643 = 0.7357.

By referring to the standard normal distribution table or using a statistical software, we can find the z-value associated with an area of 0.7357. In this case, the z-value is approximately 0.611, indicating that the value of z for which the area to the right is 0.2643 is approximately 0.611.

The number of intervals that feel that America is doing about the right amount to protect the environment is 0.487, and 0.551 intervals

To find the number of adults who feel that America is doing about the right amount to protect the environment, we need to use the confidence interval proportion formula

CI = p ± Zα/2 * √(p * (1-p)/n

where:

p = sample proportion = 519/1000 = 0.519

n = sample size = 1000

Zα/2 = the critical value for the desired confidence level = 1.96

By substuting the values, we get:

CI = 0.519 ± 1.96 * √(0.519 * (1-0.519) / 1000)

Diatomic molecules can move through rotation and vibration. Quantum mechanics quantizes energy, and the Schrödinger equation provides solutions for studying molecular energy levels.

When examining molecular energy levels, diatomic molecules exhibit rotational and vibrational motions independent of their center of mass. In quantum mechanics, energy is quantized, meaning it can only be added or subtracted in specific discrete quantities.

The Schrödinger equation provides solutions for various quantum systems. Two solutions, the hydrogen atom and the harmonic oscillator, are particularly useful for studying molecules. The hydrogen atom has a spherically symmetric potential energy, which allows us to determine the allowed values of angular momentum (L) using the equation L^2 = l(l + 1)ℏ^2, where l represents different angular momentum states (l = 0, 1, 2, 3, ...).

Similarly, diatomic molecules have a spherically symmetric potential energy function U(r) = 0 for rotation. As a result, we can utilize the same equation for the allowed angular momentum states as in the case of the hydrogen atom, enabling us to analyze and understand the rotational energy levels of diatomic molecules.

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Which statement is true about the angles?

a) Measure of angle A = 20 degrees

b) Measure of angle B = 60 degrees

c) Angle A and Angle B are complementary

d) Measure of angle A + measure of angle C = 100 degrees

Answer:

a) Measure of angle A = 20 degrees

Step-by-step explanation:

It is known that the sum of angles in a triangles = 180°

We are given these values in the question

Triangle ABC has the angle measures shown. Measure of angle A = (2 x) degrees. Measure of angle B = (5 x) degrees. Measure of angle C = (11 x) degrees.

Therefore,

Angle A + Angle B + Angle C = 180°

2x + 5x + 11x = 180°

18x = 180°

x = 180°/ 18

x = 10°

Finding each of the angles

Angle A = 2x = 2 × 10 = 20°

Angle B = 5x = 5 × 10 = 50°

Angle C = 11x = 11 × 10 = 110°

Therefore, the correct option is:

a) Measure of angle A = 20 degrees

The true statement is required.

The true statement is that \(m\angle A=10^{\circ}\)

\(\angle A=2x\)

\(\angle B=5x\)

\(\angle C=11x\)

The sum of the angles in a triangle is \(180^{\circ}\)

So

\(\angle A+\angle B+\angle C=180\\\Rightarrow 2x+5x+11x=180\\\Rightarrow 18x=180\\\Rightarrow x=\dfrac{180}{18}\\\Rightarrow x=10\)

\(\angle A=2x=2\times10\\\Rightarrow \angle A=10^{\circ}\)

The true statement is that \(m\angle A=10^{\circ}\)
