The total number of social security numbers that are possible are 900,000,000.

In the social security number first digit can only fall between 1 and 9, leaving us only nine options because the first three digits cannot all be zeros. There are still 10 possibilities for each of the second and third digits because they may both still be any integer between 0 and 9.

Therefore, the total number of different social security numbers that can be formed is using the combinations,

= 9 × 10⁸

= 900,000,000

So, there are 900,000,000 different possible social security numbers.

By the definition of the composition of functions, we have (f ∘ g)(x) = f(g(x)).The value of (f ∘ g)(5) is 22.

Given that g(5) = 7 and f(7) = 22, we can substitute these values into the composition expression to find (f ∘ g)(5):

(f ∘ g)(5) = f(g(5))

Since g(5) = 7, we have:

(f ∘ g)(5) = f(7)

And since f(7) = 22, we can conclude:

(f ∘ g)(5) = 22

Therefore, the value of (f ∘ g)(5) is 22.

In other words, when we apply the function g to the input 5, it yields the value 7, and then when we apply the function f to the result 7, it yields the value 22. So, the composition of functions (f ∘ g) evaluated at 5 is equal to 22.

To summarize:

(f ∘ g)(5) = 22

Answer:

103.5 m²

Step-by-step explanation:

To find the area of a right trapezoid, you can decompose it into a rectangle and a triangle. The sum of the area of  the rectangle and the triangle gives the area of the trapezoid.

For the right trapezoid attached below, the area can be gotten by:

Area of rectangle = length × breadth = 9 × 8 = 72 m²

Area of triangle = 1/2(base × height) = 0.5 × 7 × 9 = 31.5 m²

Area of trapezoid = Area of rectangle + Area of triangle = 72 m² + 31.5 m² = 103.5 m²

To find the left, right, mean, and standard deviation for the normalcdf, you can follow these two steps:

The mean of the normal distribution is denoted by μ (mu), and the standard deviation is denoted by σ (sigma). If you have been given the mean and standard deviation, you can skip this step. If not, you need to calculate these values.

For example, let's say you are given the following normal distribution:

X ~ N(50, 10)

Here, the mean is 50, and the standard deviation is 10.

Once you have the mean and standard deviation, you can use them to determine the left and right bounds for the normalcdf.

The left bound is the smallest value in the range of values that you are interested in. The right bound is the largest value in the range of values that you are interested in.

For example, let's say you want to find the area under the normal distribution between x = 40 and x = 60. To do this, you need to find the left and right bounds.

Using the mean and standard deviation from Step 1:

μ = 50

σ = 10

To find the left bound, you subtract the mean from the left endpoint

left bound = 40 - μ = 40 - 50 = -10

To find the right bound, you subtract the mean from the right endpoint:

right bound = 60 - μ = 60 - 50 = 10

So the left and right bounds for the normalcdf are -10 and 10, respectively. You can then use these values to find the area under the normal distribution using a calculator or statistical software.

The correct answer is a) Osmotic pressure.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

Osmotic pressure is indeed a colligative property, which means it depends on the concentration of solute particles in a solution and not on the nature of the solute itself. Osmotic pressure is the pressure required to prevent the flow of solvent molecules into a solution through a semipermeable membrane.

On the other hand, options b), c), and d) are all colligative properties:

b) Elevation of a boiling point: Adding a non-volatile solute to a solvent increases the boiling point of the solution compared to the pure solvent.

c) Freezing point: Adding a non-volatile solute to a solvent decreases the freezing point of the solution compared to the pure solvent.

d) Depression in freezing point: Adding a solute to a solvent lowers the freezing point of the solvent, causing the solution to freeze at a lower temperature than the pure solvent.

Therefore, the correct answer is a) Osmotic pressure.

The area under the curve of f(x) = -x^2 + 9x between x = -2 and x = 6 is 120 square units.

To find the area under the curve, we can use the Fundamental Theorem of Calculus. According to the theorem, if F(x) is the antiderivative of f(x), then the area under the curve between two points, say a and b, is given by the definite integral of f(x) from a to b:

Area = ∫[a to b] f(x) dx = F(b) - F(a)

First, let's find the antiderivative of f(x). We can use the power rule of integration. The antiderivative of -x^2 is (-1/3)x^3, and the antiderivative of 9x is (9/2)x^2. Adding these two antiderivatives, we get the antiderivative of f(x) as (-1/3)x^3 + (9/2)x^2.

Now, we can calculate the area under the curve by evaluating the antiderivative at the upper and lower limits:

Area = [(-1/3)(6)^3 + (9/2)(6)^2] - [(-1/3)(-2)^3 + (9/2)(-2)^2]

    = [(-1/3)(216) + (9/2)(36)] - [(-1/3)(-8) + (9/2)(4)]

    = [-72 + 162] - [8/3 + 18]

    = 90 - (8/3 + 54/3)

    = 90 - 62/3

    = 270/3 - 62/3

    = 208/3

    = 69.33 (rounded to two decimal places)

The area under the curve of f(x) = -x^2 + 9x between x = -2 and x = 6 is 208/3 square units, which is approximately 69.33 square units.

1 + \(x^3\) + \((x^6)\)/2! + \((x^9)\)/3! + \((x^{12} )\)/4! + ...

This series can be rewritten as:

∑ \((x^{(3n)} )/n!\) for n=0 to infinity.

This expansion resembles the Maclaurin series for \(e^x\), which is:

\(e^x\) = ∑ \(x^n\)/n! for n=0 to infinity.

However, in the given series, the powers of x are in multiples of 3. To adjust the standard exponential function to match the provided series, you can use the substitution \(x^3\) = u:

\(e^u\) = ∑ \(u^n\)/n! for n=0 to infinity.

Now, substitute \(x^3\) back for u:

To evaluate if the athletes have improved in their flexibility, the physical therapist should run a paired t-test.

A paired t-test is appropriate in this scenario because the therapist is comparing the flexibility of the same group of athletes before and after the yoga training program. This test allows for the comparison of the mean flexibility scores within the same group, taking into account individual differences among the athletes.

Here's how the paired t-test works step-by-step:

1. First, the therapist would collect flexibility measurements from the 50 athletes before starting the yoga training program.
2. After the six-week program, the therapist would measure the athletes' flexibility again.
3. The therapist would then calculate the difference in flexibility scores for each athlete by subtracting the pre-training flexibility score from the post-training flexibility score.
4. Next, the therapist would calculate the mean difference in flexibility scores for the entire group.
5. The therapist would also calculate the standard deviation of the differences.
6. Using these calculated values, the therapist would perform the paired t-test to determine if there is a statistically significant difference in flexibility before and after the yoga training program.
7. The result of the t-test would provide a p-value, which indicates the probability of obtaining the observed difference in flexibility scores by chance alone.
8. If the p-value is below a predetermined significance level (typically 0.05), the therapist can conclude that the athletes' flexibility has improved significantly due to the yoga training program.

By running a paired t-test, the physical therapist can objectively evaluate whether the athletes have experienced a statistically significant improvement in their flexibility after participating in the six-week yoga training program.

Answer:

B is the answer!

Step-by-step explanation:

The differential equation y''+2y'+3y=0 is a second order linear differential equation. Therefore, option a is the correct answer.

What is a linear differential equation?

A differential equation is said to be linear if its dependent variable and all its derivatives occur only in the first degree and are not multiplied together. This means that the dependent variable and its derivatives appear as separate variables.

For example, the following differential equation is linear:

y′′(x) + xy′(x) + y(x) = 0

On the other hand, a nonlinear differential equation is one that involves powers or products of the dependent variable or its derivatives. For example:

y′′(x) + (y(x))² = 0

What is a second order differential equation?

A differential equation is said to be of the second order if it contains two derivatives of the dependent variable. For example, the differential equation:

3y′′(x) + 2y′(x) + y(x) = 0

is a second order differential equation.

What is the solution to a second order linear differential equation?

The general solution to a second order linear differential equation of the form:

y′′(x) + p(x)y′(x) + q(x)y(x) = 0 is given by:

y(x) = c₁y₁(x) + c₂y₂(x)

where y₁(x) and y₂(x) are two linearly independent solutions of the differential equation.

The constants c₁ and c₂ are found by applying initial or boundary conditions that specify the values of y and its derivative at one or more points in the domain of the differential equation.

Hence, the differential equation y''+2y'+3y=0 is a second order linear differential equation. Therefore, option a is the correct answer.
