\(\sf x = 9\)

Answer:

Step-by-step explanation:

Since parallel lines cut the transversals proportionally, we can set the following equation and solve for x;

c = 1/2, and the pdf is fx(x) = { 1/2 \((1-x^{2} )^{-1}\), −1 ≤ x ≤ 1or 0 otherwise and cdf of X is: FX(x) = { 0, x ≤ -1 or -1/2 \(tan^{-1}(x/\sqrt{1-x^{2} )}\) + 1/2, -1 < x < 1 or 1 ,x ≥ 1

(a) To find c, we need to integrate the pdf over its support and set the result equal to 1 since the pdf must integrate to 1 over its entire support. Therefore, we have:

1 = ∫c \((1-x^{2} )^{-1}\) dx from -1 to 1

Using the substitution u = 1 - \(x^{2}\), we have:

1 = c∫ \(u^{-1/2}\) dx from 0 to 1

Solving the integral, we get:

1 = 2c

Therefore, c = 1/2, and the pdf is:

fx(x) = {

1/2 \((1-x^{2} )^{-1}\) , −1 ≤ x ≤ 1

0 otherwise

To sketch the pdf, we can notice that it is symmetric about x = 0 and that it approaches infinity as x approaches ±1. Therefore, it will have a peak at x = 0 and decrease as we move away from x = 0 in either direction.

(b) To find the cdf of X, we can integrate the pdf from negative infinity to x for each value of x in the support of the pdf. Therefore, we have:

FX(x) = ∫fX(t) dt from -∞ to x

For x ≤ -1, FX(x) = 0, since the pdf is zero for x ≤ -1. For -1 < x < 1, we have:

FX(x) = ∫1/2 \((1-t^{2} )^{-1}\) dt from -1 to x

Using the substitution u = \(t^{2}\) - 1, we have:

FX(x) = -1/2 ∫\((x^{2} -1)^{-1/2}\) du

Solving the integral, we get:

FX(x) =  -1/2 \(tan^{-1}(x/\sqrt{1-x^{2} )}\)  + 1/2

For x ≥ 1, we have FX(x) = 1, since the pdf is zero for x ≥ 1. Therefore, the cdf of X is:

FX(x) = {

0 x ≤ -1

-1/2 \(tan^{-1}(x/\sqrt{1-x^{2} )}\)  + 1/2 -1 < x < 1

1 x ≥ 1

To sketch the cdf, we can notice that it starts at 0 and increases gradually from x = -1 to x = 1, where it jumps to 1. The cdf is also symmetric about x = 0, similar to the pdf.

The power series expansion of \(e(-3x3 - 1 + 3x3 - 2/9) and \(e3x3-2/9] is given as [xn / n!] from n=0 to infinity. Multiplying these two expansions and simplifying, we get \(e-3x3 * e(3x3-2/9)\) = \([(-1)n (3n * (3n - 2)) / n!] x3n\) from n=0 to infinity. limx0 from n=0 to infinity = 1/14 * \([(-1)n (3n * (3n - 2)) / n!]\)* infinity. Hence, the given limit does not exist.

Using power series, evaluate the limit as x approaches 0 of \(e^(-3x^3 - 1 + 3x^3 - 2/9) * (x^6/14x^9).\)

The power series expansion of \(e^x\) is given as:∑[x^n / n! ] from n=0 to infinity

Therefore,

\(e^-3x^3 = ∑[-3x^3]^n / n!\) from n=0 to infinity= ∑[(-1)^n 3^n x^3n] / n! from n=0 to infinity And

\(e^3x^3-2/9 = ∑[(3x^3)^n / n!] * (1 - 2/(9*3^n))\) from n=0 to infinity

= ∑[(3^n \(x^3n\)) / n!] * (1 - 2/(9*\(3^n\))) from n=0 to infinity Multiplying these two power series expansion and simplifying, we get:\(e^-3x^3 * e^(3x^3-2/9)\) = ∑\([(-1)^n (3^n * (3^n - 2)) / n!] x^3n\) from n=0 to infinity

Therefore,

limx→0​ \(e^(-3x^3 - 1 + 3x^3 - 2/9) * (x^6/14x^9)\)

limx→0​ \(x^-3\) from n=0 to infinity= 1/14 *\(∑[(-1)^n (3^n * (3^n - 2)) / n!]\)* infinity from n=0 to infinity= infinity.

The probability of two independent events occurring, we multiply their individual probabilities.

Let's start by determining the probability of the coin showing tails.

Since it is a fair coin, there are two equally likely outcomes: heads or tails.

The probability of the coin showing tails is 1/2.

Next, we consider the number cube.

It is a standard six-sided die, and we want to find the probability of rolling a three, four, or six.

Out of the six possible outcomes (numbers 1 to 6), three of them satisfy our condition (3, 4, and 6).

The probability of rolling a three, four, or six is 3/6 or 1/2.

The one is not a characteristic of a normal curve is its spread increases as its mean increases that is Option 2.

One of the numerical values that is frequently calculated in both descriptive and inferential statistics is statistical variance. If we know the mean, the value of each data point, and the number of samples, we can determine this value.

The spread of scores in a data set normally increases as the variance of that data set increases. The main reason for this is because variance is a number that represents the average departure of each data point from the mean.

Because the normal distribution is symmetrical on both sides of the mean and is a continuous probability distribution, the right side of the center is the opposite of the left side.

Probability is represented by the area under the normal distribution curve, and the total area under the curve equals one.

The effective annual interest rate of the investment is approximately 5.4%.

To find the effective annual interest rate, we need to consider the compounding frequency and the total accumulated amount after the specified time period. In this case, the investment is compounded monthly, and it accumulates to $773.45 after 2 years.

Convert the nominal interest rate to the monthly rate:

Since the interest is compounded monthly, we need to convert the nominal yearly interest rate to the monthly rate. Assuming a nominal interest rate of \(\(r\)\), the monthly rate can be calculated as \(\(i = \frac{r}{12}\)\).

Calculate the effective annual interest rate:

To find the effective annual interest rate, we can use the formula:

\(\((1 + i)^{12} = (1 + \text{effective annual interest rate})\)\).

Rearranging the formula and solving for the effective annual interest rate, we have:

\(\(\text{effective annual interest rate} = (1 + i)^{12} - 1\)\).

Substitute the values and calculate:

In this case, the accumulated amount is $773.45 after 2 years. By substituting the values into the formula, we have:

\(\(773.45 = 700(1 + \frac{r}{12})^{24}\)\).

Solving for \(\(r\)\), we find:

\(\(\frac{r}{12} \approx 0.0045\)\).

Converting the monthly rate to the effective annual interest rate, we get:

\(\((1 + \frac{r}{12})^{12} - 1 \approx 0.054\),\) which is equivalent to 5.4%.

Therefore, the effective annual interest rate of the investment is approximately 5.4%.

y = mx + c

Here the model equation

c = 0.75h, where c is the total cost to buy hotdogs

h is the number of hotdogs bought

And 0.75 is the price of one hotdog

Now we can clearly say that c = 0.75h will make a straight line coordinate plane.

Now comparing the equation with slope intercept equation of straight line we get,

In probability theory, a Venn diagram is a diagrammatic representation of sets that shows all possible logical relations between them. Venn diagrams are widely used in probability and statistics to visualize the relationship between different sets of data.

The given Venn diagram shows the relationship between three sets, A, B, and C. In order to calculate probabilities using a Venn diagram, we need to know the number of elements or members in each set, as well as any overlapping regions.

We can then use these numbers to calculate the probability of different outcomes.Let's consider two possible probabilities from the given Venn diagram:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22. The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3The first probability can be calculated by dividing the number of elements in the overlapping region of sets A and B (which is 0.1) by the total number of elements in set B (which is 0.5).

This gives us a probability of 0.22 or 22%.The second probability can be calculated by dividing the number of elements in the union of sets B and C (which is 0.2) by the total number of elements in either set B or set C (which is 0.6). This gives us a probability of 1/3 or approximately 33%.

Therefore, the correct probabilities are:1.

The probability that an element is in set A and set B but not in set C is 0.1/0.5 = 0.22.

The probability that an element is in set B or set C but not in set A is 0.2/0.6 = 1/3

Answer:

x = 2

x = 1/2

Step-by-step explanation:

To solve the given equation (x-2)(2x-1) = 0, we need to find the values of 'x' that make the left-hand side of the equation equal to zero. For this, we need to use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.

Using the zero product property, we can set each factor equal to zero and solve for 'x'.

First factor: x - 2 = 0

Adding 2 to both sides, we get:

x = 2

Second factor: 2x - 1 = 0

Adding 1 to both sides, we get:

2x = 1

Dividing by 2 on both sides, we get:

x = 1/2

Therefore, the solutions to the given equation (x-2)(2x-1) = 0 are x = 2 and x = 1/2.

We can verify our solutions by plugging them back into the original equation and checking if the left-hand side equals zero.

When x = 2, we have:

(x-2)(2x-1) = (2-2)(2(2)-1) = 0, which is true.

When x = 1/2, we have:

(x-2)(2x-1) = (1/2-2)(2(1/2)-1) = (-3/2)(0) = 0, which is also true.

Therefore, our solutions are correct.

FYI, you could've also multiplied the polynomials to get a quadratic equation, though this is terribly inefficient for this case.

Answer:

In short, to solve the equation (x-2)(2x-1) = 0, we use the zero product property by setting each factor equal to zero and solving for x. The solutions are x = 2 and x = 1/2.

Step-by-step explanation:

The equation (x-2)(2x-1) = 0 can be solved by finding the values of x that make the left-hand side of the equation equal to zero.

To do this, we can use the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

Therefore, we set each factor equal to zero and solve for x:

x-2 = 0 or 2x-1 = 0

Solving each equation for x, we get:

x = 2 or x = 1/2

So the solutions to the equation (x-2)(2x-1) = 0 are x = 2 and x = 1/2.

\(\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ \cfrac{-2}{3}} ~\hfill \stackrel{reciprocal}{\cfrac{3}{-2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{-2} \implies \cfrac{3}{ 2 }}}\)

let's see if that's true

\(R(\stackrel{x_1}{9}~,~\stackrel{y_1}{-6})\qquad S(\stackrel{x_2}{17}~,~\stackrel{y_2}{-5}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-5}-\stackrel{y1}{(-6)}}}{\underset{\textit{\large run}} {\underset{x_2}{17}-\underset{x_1}{9}}} \implies \cfrac{-5 +6}{8} \implies \cfrac{ 1 }{ 8 } ~~ \bigotimes ~~ \textit{not perpendicular}\)

Answer:

Step-by-step explanation:

No they are not perpendicular.

Perpendicular lines have slopes that are negative reciprocals of each other.

PQ slope = -12 - -10/-5 --8 = -2/3

RS slope = -5 - -6/17 -9 = 1/8

Slope are not negative reciprocals - the lines are not perpendicular.

Slope formula is m = y2 - y1/x2 - x1

Use this to determine slope.

For example if the the slope of RS was 3/2 - the lines would be perpendicular.
