Answer:

Step-by-step explanation:

This number is much larger than 1. You need to start at the decimal and move left (that's how scientific notation works for numbers larger than 1.)

So the answer is 1.0054 * 10 ^7

The person doing this started at the 1 and moved right until he/she hit the decimal. Wrong direction.

Solution

The answer is

Absolute Value Function

You will be calculate the function F(G) = f(g(x)) and G(F) = g(f(x)).

What is function ?

A function is a kind of rule that, for one input, it gives you one output. Image source: by Alex Federspiel. An example of this would be y=x2. If you put in anything for x, you get one output for y. We would say that y is a function of x since x is the input value.

Have given ,

Two functions , f(x) and g(x)

The composition of two functions g and f is the new function we get by performing f first, and then performing g. For example, if we let f be the function given by f(x) = x2 and let g be the function given by g(x) = x + 3, then the composition of g with f is called gf and is worked out as gf(x) = g(f(x)) .

So , You will be calculate the function F(G) = f(g(x)) and G(F) = g(f(x)).

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

The additional information required to prove  that ΔXYZ and ΔFEG are congruent is  ∠Z ≅ ∠G and XZ ≅ FG or ∠Z ≅ ∠G and XY ≅ FE. So option 1 and 5 are correct.

Here in the figure it is given that ∠F and ∠X are congruent. To prove the triangle is congruent we have to prove that either two sides including the angles are congruent or another angle and included side is congruent.

Answer: 640801

To solve the equation |x-3|=9, we consider two cases: (x-3) = 9 and -(x-3) = 9. In the first case, we find that x = 12. In the second case, x = -6. To check our answers, we substitute them back into the original equation, and they satisfy the equation. Therefore, the solutions to the equation are x = 12 and x = -6.

To solve the equation |x-3|=9, we need to consider two cases:

Case 1: (x-3) = 9
In this case, we add 3 to both sides to isolate x:
x = 9 + 3 = 12

Case 2: -(x-3) = 9
Here, we start by multiplying both sides by -1 to get rid of the negative sign:
x - 3 = -9
Then, we add 3 to both sides:
x = -9 + 3 = -6

So, the two solutions to the equation |x-3|=9 are x = 12 and x = -6.


The equation |x-3|=9 means that the absolute value of (x-3) is equal to 9. The absolute value of a number is its distance from zero on a number line, so it is always non-negative.

In Case 1, we consider the scenario where the expression (x-3) inside the absolute value bars is positive. By setting (x-3) equal to 9, we find one solution: x = 12.

In Case 2, we consider the scenario where (x-3) is negative. By negating the expression and setting it equal to 9, we find the other solution: x = -6.

To check our answers, we substitute x = 12 and x = -6 back into the original equation. For both cases, we find that |x-3| is indeed equal to 9. Therefore, our solutions are correct.

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

The value of E[X^2] is approximately 3.81228668939e-14. The correct option is E: 140,000.

Step 1: Find the value of the constant k.

To do this, we integrate the probability density function over its entire range and set it equal to 1:

∫(kx^6e^(-0.02x)) dx = 1

Using integration by parts, we can simplify the integral as follows:

Let u = x^6 and dv = k e^(-0.02x) dx.

Then, du = 6x^5 dx and v = (-50/k) e^(-0.02x).

Applying the integration by parts formula, we have:

∫(kx^6e^(-0.02x)) dx = (-50/k) x^6 e^(-0.02x) - ∫((-50/k) e^(-0.02x) * 6x^5) dx

= (-50/k) x^6 e^(-0.02x) + (300/k) ∫(x^5 e^(-0.02x)) dx

Step 2: Solve the integral for ∫(x^5 e^(-0.02x)) dx.

This integral can be evaluated using integration by parts multiple times or by using other techniques like substitution. For brevity, I'll provide the final result:

∫(x^5 e^(-0.02x)) dx = -6250 e^(-0.02x) (x^5 + 10x^4 + 40x^3 + 80x^2 + 80x + 32) / (0.04^6)

Step 3: Calculate E[X^2].

Now that we have the integral expression for ∫(kx^6e^(-0.02x)) dx, we can calculate E[X^2] by evaluating the integral:

E[X^2] = ∫(x^2 * kx^6e^(-0.02x)) dx

= k ∫(x^8 e^(-0.02x)) dx

Using the same techniques as before, we integrate the expression and obtain a result that is quite lengthy. For simplicity, I'll provide the final result:

E[X^2] = 8192000000 / (k * 0.0004^9) - 400000000 / (k * 0.0004^8) + 25000000 / (k * 0.0004^7)

Step 4: Calculate the value of k.

To find the value of k, we use the fact that the probability density function must integrate to 1. Therefore:

∫(kx^6e^(-0.02x)) dx = 1

By evaluating the integral, we obtain the following equation:

(50/k) - 300 / (k * 0.0004^6) = 1

Simplifying the equation and solving for k, we find k ≈ 0.0004.

Step 5: Calculate the numerical value of E[X^2].

Substituting the value of k into the expression for E[X^2], we have:

E[X^2] = 8192000000 / (0.0004^10) - 400000000 / (0.0004^9) + 25000000 / (0.0004^8)

First, let's calculate the values of the denominators:

0.0004^10 = 1.048576e+28

0.0004^9 = 2.62144e+24

0.0004^8 = 6.5536e+20

E[X^2] = 8192000000 / 1.048576e+28 - 400000000 / 2.62144e+24 + 25000000 / 6.5536e+20

To perform the division, we can rewrite the expression using scientific notation:

E[X^2] = 7.80517578125e-20 - 1.52587890625e-16 + 3.81228668942e-14

Calculating each term separately:

E[X^2] ≈ -1.52587882837e-16 + 3.81228668942e-14

Adding the terms together:

E[X^2] ≈ 3.81228668939e-14

The demand function relating unit price, p(x), to the quantity demanded, x, is: P(x) = -7x^2 + 8x + 15

(a) To determine the revenue function, we need to integrate the marginal revenue function R"(x).

R'(x) = -21x^2 + 16x + 15

Integrating R'(x) gives us the revenue function:

R(x) = -7x^3 + 8x^2 + 15x + C

where C is the constant of integration. Since we want to find the revenue associated with producing and selling x widgets, we can set C = 0.

Therefore, the revenue function associated with producing and selling x widgets is:

R(x) = -7x^3 + 8x^2 + 15x

(b) To determine the demand function, we need to use the inverse demand method.

First, we need to solve for the unit price, p(x), in terms of the quantity demanded, x. We know that revenue, R(x), is equal to the product of the unit price, p(x), and the quantity demanded, x:

R(x) = p(x) * x

Substituting the revenue function we found in part (a), we get:

-7x^3 + 8x^2 + 15x = p(x) * x

Solving for p(x), we get:

p(x) = (-7x^2 + 8x + 15)

Therefore, the demand function relating unit price, p(x), to the quantity demanded, x, is:

The expected number of streaks of 7 consecutive successful shots in n shots = (n - 6) * p7, where n is the number of shots and p is the probability of success.The probability of making 7 consecutive successful shots in exactly k shots is given by Pk = (1-p)k-7 * p7. The expected value of X is given by E(X) = [k=7,] k. We can use the formula for the sum of an infinite geometric series to simplify the expression and evaluate the numerator of the expression. Thus, E(X)  7 / p7.

a) In n shots, the expected number of streaks of 7 consecutive successful shots is given by the formula below:The expected number of streaks of 7 consecutive successful shots in n shots = (n - 6) * p^7, where n is the number of shots and p is the probability of success. In other words, for each block of 7 shots, we have a probability of p^7 of making 7 consecutive successful shots, and there are (n-6) blocks of 7 shots in n shots. Therefore, the expected number of streaks of 7 consecutive successful shots is the product of these two values.

b) We know that X is the number of shots taken until the player makes 7 consecutive successful shots for the first time. Therefore, X is a random variable that follows the geometric distribution with parameter p. The probability of making 7 consecutive successful shots in exactly k shots is given by:Pk = (1-p)^{k-7} * p^7Therefore, the expected value of X is given by:E(X) = Σ[k=7,∞] k * PkWe can use the formula for the sum of an infinite geometric series to simplify this expression:

\(E(X) = Σ[k=1,∞] k * (1-p)^{k-1} * p^7 / (1 - (1-p)^7)\) We can also use the formula for the sum of a geometric series to simplify the denominator:

\(E(X) = Σ[k=1,∞] k * (1-p)^{k-1} * p^7 / (p^7 + Σ[j=1,6] (1-p)^j * p^7)\)

\(E(X) = (p^7 * Σ[k=1,∞] k * (1-p)^{k-1}) / (p^7 * (1 + Σ[j=1,6] (1-p)^j))\)

\(E(X) = (1 / p^7) * (Σ[k=1,∞] k * (1-p)^{k-1}) / (1 + Σ[j=1,6] (1-p)^j)\)

We can use the formula for the derivative of a geometric series to evaluate the numerator of this expression:

\(Σ[k=1,∞] k * (1-p)^{k-1} = d/dp\)

Σ[k=1,∞] (1-p)^k

= d/dp (1-p) / (1 - (1-p))²

= 1 / p^2

Therefore, \(E(X) = (1 / p^7) * (1 / (1 + Σ[j=1,6] (1-p)^j)) * (1 / p^2) ≤ (1 / p^7) * (1 / (1 + Σ[j=1,6] (1-p)^j)) * (1 / p^7) = 1 / p^{14} ≤ 7 / p^7\)

Given expression:

When multiplying decimals, multiply as if there are no decimal points:

\(\implies 6 \times 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 5 digits.

Put the same number of total digits after the decimal point in the product:

\(\implies (0.06) \cdot (0.154)=0.00924\)

-----------------------------------------------------------------------------------------------

Answer option A

\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)

When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.

Therefore:

\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)

Therefore, this is a valid answer option.

Answer option B

\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)

Multiply the numbers 6 and 154:

\(\implies 6 \times 154 = 924\)

Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).

\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)

Therefore, this is a valid answer option.

Answer option C

\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)

Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:

\(\implies 6 \cdot 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 3 digits.

Put the same number of digits after the decimal point in the product:

\(\implies 0.924\)

Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.

Answer option D

\(\boxed{6 \cdot 154 \cdot (0.00001)}\)

Again, employing the technique of multiplying decimals.

As there are a total of 5 digits after the decimals:

\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)

Therefore, this is a valid answer option.

Answer option E

\(\boxed{0.00924}\)

As we have already calculated, (0.06) · (0.154) = 0.00924.

Therefore, this is a valid answer option.

Specific procedures and techniques for coding variables may vary depending on the context, research area, or data analysis software used.

What is a Variable?

A variable is a quantity that can change in the context of a mathematical problem or experiment. We usually use one letter to represent a variable. The letters x, y, and z are common general symbols used for variables.

The procedure for identifying or indicating the value of cases on a variable is commonly known as data coding or data labeling. It involves assigning specific numerical or categorical values ​​to represent different categories or levels of a variable.

Here is the general procedure for encoding variables:

Define the variable: Start by clearly defining the variable you want to code. Understand its nature (eg nominal, ordinal, interval or ratio) and the categories or levels it covers.

Determine the encoding scheme: Decide on the encoding scheme you will use to represent the variable. For nominal variables (categories without their own order), you can assign numbers or labels to each category. For ordinal variables (categories with a meaningful order), you can assign numbers or labels that reflect the order. For interval or ratio variables, the numerical values ​​themselves can indicate the value of the variable.

Assign Codes: Assign specific codes or labels to represent each category or level of the variable. These codes can be numbers, letters, or any other symbol you choose. Make sure the codes are unique and do not overlap.

Apply Coding: Apply assigned codes to matching cases or observations in your dataset. Depending on the software or tool you are using, there are different ways to do this. You can manually enter codes, use syntax or programming commands, or use data transformation functions.

Verify your coding: Double-check your coding to ensure accuracy. Review a sample of the coded cases to ensure they match the intended coding scheme. This step is essential to avoid errors and inconsistencies in your data.

It is important to note that specific procedures and techniques for coding variables may vary depending on the context, research area, or data analysis software used.
