assume that movement of a molecule is limited. it can move to the opposite side of the container or stay where it is. if the movement is random, what is the probability (0-100%) that the molecule will move to the opposite side?

Answer:

[tex]a_{n}[/tex] = 2n - 6

Step-by-step explanation:

there is a common difference between consecutive terms , that is

- 2 - (- 4) = 0 - (- 2) = 2 - 0 = 2

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = - 4 and d = 2 , then

[tex]a_{n}[/tex] = - 4 + 2(n - 1) = - 4 + 2n - 2 = 2n - 6

the rule is then 2n - 6

The probability that it rained at that game is 0.49.

Probability is the the ratio of a particular event with total number of event. It tells the possibility that an event can occur.

Probability that it rains P(R) = 0.60

probability that it won't rain P(R') = 1-0.60

= 0.4

Red sparrows have a past record of 4 wins and 5 loses when it does not rain, that is

P( winning/R') = 4/9                 (win% = 4/total that is 5+4 which is 9)

P( lose/R') = 5/9                       (lose % = 5/total)

When it rain the past record is 2 wins and 7 loses

P( win/R ) = 2/9

P( lose/R ) = 7/9

P (win) = P(R)*P(win/R) + P(R')*P(win/R')

= 4/9*0.4 + 2/9*0.6

If red sparrows win, then the probability that it rained at game

P (R/win) = P ( R η win) / P (win)

= 0.49

Therefore, we can conclude that the the probability that it rained at that game is 0.49.

Answer:

1 hour and 40 minutes

Step-by-step explanation:

60 minutes in an hour

we have 100 minutes

now we have 40 minutes left

can 40 minutes make another 60?

No.

so 100 minutes make

The polar form of the rectangular form - 9 - i 9√3 is 18 · [cos (4π / 3) + i sin (4π / 3)]. (Correct choice: A)

Herein we find a complex number in rectangular form, that is, a complex number of the form a + i b, whose polar form has to be found. Complex numbers in polar form are defined by the following expression:

z = r · (cos θ + i sin θ)

r = √(a² + b²)

θ = tan⁻¹ (b / a)

Where:

If we know that a = - 9 and b = - 9√3, then the complex number in polar form is:

r = √[(- 9)² + (- 9√3)²]

r = 18

θ = tan⁻¹ √3

θ = 4π / 3

The polar form is 18 · [cos (4π / 3) + i sin (4π / 3)].

The equation of his allowance in slope-intercept form is y = 0.5x + 8

He received $18 in allowance the week he did 20 chores.

He received $12 in allowance the week he did 8 chores.

The ordered pairs will be (8,12) and (20,18)

The slope intercept form is

y = mx + b

Where m is the slope

b is the y intercept

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values in the equation

m = (18-12)/(20-8)

m = 6/12

Now we have to find b,

Substitute the value of any ordered pair in the slope intercept form

12 = 0.5×8+b

12 = 4+b

b = 12-4

b = 8

Answer: The moon

Step-by-step explanation:

The cone is the solid form that represents "If you cut me in half, my end face will remain the same. Two of my faces are the same, one is curved."

The volume of a cone is defined as the amount of space occupied by a cone in a three-dimensional plane.

∵ The volume of the cone (V )= 1/3πhr²

The number of faces of a regular cone is one, which we may partition vertically into two halves.

This means one base face and lateral face

Now, the number of faces in one half equals the number of faces in the original form.

This meets the conditions outlined in the question.

So, the cone is a solid form.

Thus, the cone is the solid form that represents "If you cut me in half, my end face will remain the same. Two of my faces are the same, one is curved."

Answer:

AB

Step-by-step explanation:

the angles DCB and ACB are supplementary angles (together 180°).

simply because the sum of all angles around a single point on one side of a line is suggests 180° (it represents a half-circle).

so, the inner angle ACB is

ACB = 180 - 50 = 130°

because the sum of all angles in a triangle is also always 180°, there are only 50° left for the other 2 angles.

so, the inner angle at C is clearly the largest angle in the triangle ABC.

the larger an angle, the longer the opposing side.

the largest angle has the longest opposing side in the triangle.

the opposing side of the inner angle C is AB. and that is therefore the longest side in the triangle ABC.

Option a is correct using algebric formulas.

(x + y)³ = x³ + y³ +3xy( x + y )

(x + y + z)² = x² + y² + z² + 2( xy + yz + zx )

So breaking it into

(( x + y )³)² = (x³ + y³ +3xy( x + y ))²

(x³ + y³ +3xy( x + y ))² = x^6 + y^6 + 9x²y²(x² + y² + 2xy) + 2( x³y³ + 3xy^4( x + y ) + 3x^4y( x + y) )

x^6 + y^6 + 9x²y²(x² + y² + 2xy) + 2( x³y³ + 3xy^4( x + y ) + 3x^4y( x + y) )

So after rearranging the terms

we get  (x + y)^6 as

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Let assume A(-3,2) B(1,5) and C (2,-3) are original coordinates

The following translation is being used: (x, y) ⇒ (x + 2, y - 3)

First, take your x-coordinates and add them by two because it is the translation utilized to solve for your x-coordinate.

You would receive the following for yours x's: A (-1, y ) B (3, y) C (4, y)

Next, remove three from each of your y-coordinates because it is the translation being utilized to solve for your y-coordinate.

You would receive the following for your y's: A (x, -1) B (x, 2) C (x, -6)

Finally, you would take each one and put it together, or piece it together.
