The distribution of a random variable Y conditional on another random variable X taking on a specific value
Equation: Pr(Y=y| X=x) = Pr(X=x, Y=y)/(Pr(X=x)) is called?

The answer is 1/10

This is simple division

The equation is (1/5÷2)

I did my work on a sheet of paper so i know i did this correctly

My explanation of my work:

Keep change flip is the operation used here

So you keep 1/5 ,change the division sign to multiplication and flip the 2/1 into 1/2 so the new equation is (1/5x1/2) the answer to that is 1/10

The number 3.8 is a rational number.

We have,

A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero.

Rational numbers can be written in the form a/b, where a and b are integers.

In the case of 3.8, it can be expressed as 38/10.

The numerator (38) and the denominator (10) are both integers.

Therefore,

The list of all the positive common divisors of 48 and 60 is:1, 2, 3, 4, 6, 12.

To find all the common divisors of 48 and 60, we need to first list the divisors of both numbers. So let's list out the divisors of both 48 and 60.

Divisors of 48:1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Divisors of 60:1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Now, we can identify the common divisors by comparing the two lists. The common divisors of 48 and 60 are:1, 2, 3, 4, 6, 12

In division, we divide a number by any other number to get another number as a result. So, the number which is getting divided here is called the dividend. The number which divides a given number is the divisor.

Answer:

angel bisector

Step-by-step explanation:

this pic explains why

The maximum value of the function y = -1 + 6cos((2π/7)(x-5)) is 5.

To find the maximum value of the function y = -1 + 6cos((2π/7)(x-5)), we can observe that the cosine function has a maximum value of 1 when the argument is 0.

In this case, the argument of the cosine function is (2π/7)(x-5). To find the maximum value of the function, we need to determine the value of x that makes the argument 0.

Setting (2π/7)(x-5) equal to 0, we have:

(2π/7)(x-5) = 0

To solve for x, we can multiply both sides by 7/(2π):

x - 5 = 0

Adding 5 to both sides:

x = 5

So, the argument of the cosine function is 0 when x = 5.

Substituting x = 5 into the original function:

y = -1 + 6cos((2π/7)(5-5))

y = -1 + 6cos(0)

y = -1 + 6(1)

y = -1 + 6

y = 5

Given the fraction of each colored chalk, Andrea is right that less than 1/2 the chalk in the bucket is blue.

Total = 2/6 + 5/12 + 3/12

Fraction of blue : Total chalk

= 5/12 : 1

Blue = 5/12 ÷ 1

The general solution of the given second-order linear ordinary differential equation is y = (c1 + c2x)e^(5x) + 22/25, where c1 and c2 are arbitrary constants.

The given differential equation is y'' - 10y' + 25y = 22. To find the general solution, we first need to find the complementary function by solving the associated homogeneous equation, which is y'' - 10y' + 25y = 0.

Assuming a solution of the form y = e^(rx), we substitute it into the homogeneous equation and obtain the characteristic equation r^2 - 10r + 25 = 0. Solving this quadratic equation, we find that r = 5 is a repeated root.

Therefore, the complementary function is of the form y_c = (c1 + c2x)e^(5x), where c1 and c2 are arbitrary constants.

Next, we find a particular solution for the non-homogeneous equation y'' - 10y' + 25y = 22. Since the right-hand side is a constant, we can assume a constant solution y_p = a.

Substituting y_p = a into the differential equation, we find that 25a = 22, which gives a = 22/25.

The force is 1.6N and the distance between them is 1.3 meters

An inverse variation from force to the square of distance is represented s:

k = Fd^2

Where k represents the variation constant

When F = 10, d = 2.

So, we have:

k = 10 * 2^2

k = 40

Substitute k = 40 in k = Fd^2

Fd^2 = 40

When d = 5, we have:

F * 5^2 = 40

This gives

25F = 40

Divide by 25

F = 1.6

Hence, the force is 1.6N

In (a), we have:

Fd^2 = 40

When F = 25, we have:

25 * d^2 = 40

This gives

25d^2 = 40

Divide by 25

d^2 = 1.6

Take the square root of both sides

d = 1.3

Hence, the distance between them is 1.3 meters

Answer:

Multiply n by the cost of the box.

Step-by-step explanation:

hey there,

< For these kinds of problems I always like making ratio tables.

2 boxes → $4.95

n boxes → $?

To find the thing we don't know in any ratio table (marked by "?"), you have to multiply the two opposites and then divide by the last one standing. I know that sounds confusing so let me explain...

"Two opposites" means the two values that are right across from each other, but do not include the unknown ("?"). In this example, the two diagonally across from each other are "n" amd "4.95". "2" and "?" can't be right across from each other because one of those is a "?".

Multiply the two opposites. n × 4.95. Let's not actually simplify since this isn't what we are doing here in this question and leave it like this:

n × 4.95 = (n × 4.95)

Now that we found that, we have to divide it by the last number available. The last number available that we haven't used yet is "2" (it obbviously can't be the unkown number "?").

(n × 4.95)/2

Whatever the result of the above equation is, is the answer.

(n × 4.95)/2 = ?

In our situation, "?" means "c". This is how you would solve any ratio table, it might seem tricky at first but it's actually super easy.

In this question, we are not asked to divide by two because they want to know a method of solving using the cost of one box.

\(\frac{(n*4.95)}{2} / 2\)

n × (4.95/2)

4.95/2 is the cost of one box. Multiply that by "n" and there is your final answer. >

Answer:

BC = \(\frac{12}{13}\)

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

BC² + AC² = AB²

BC² + (\(\frac{5}{13}\) )² = 1²

BC² + \(\frac{25}{169}\) = 1 ( subtract \(\frac{25}{169}\) from both sides )

BC² = \(\frac{169}{169}\) - \(\frac{25}{169}\) = \(\frac{144}{169}\) ( take square root of both sides )

BC = \(\sqrt{\frac{144}{169} }\) = \(\frac{12}{13}\)
