Shawn is playing a game with a set of cards. Half of them are blue and the other half are yellow. In the game, the player guesses the color of the top card, looks at the card, and returns the card to the deck. The player continues to do this, shuffling the deck after each guess.

Shawn has guessed the first three attempts as "blue” and has been correct on each guess. He says he will guess "yellow” for the next card since a yellow card is due to happen. Is Shawn’s reasoning correct?

Yes, Shawn has guessed well so far, so it is clear that he cannot miss.
No, all of the cards have been blue so far, so the next one must also be blue.
Yes, half of the cards are yellow, so the fourth card should be yellow to compensate for the first three cards being blue.
No, the law of large numbers says that the proportion of yellow cards should approach the true probability after many trials.

Answer:

Dividing negative exponents is almost the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.

Step-by-step explanation:

Answer:

The value of a is 63° and the value of b is 27°

Step-by-step explanation:

In the given figure

∵ OA, OB, and OC are radii of the circle O

→ The radii of a circle are equal

∴ OA = OB = OC

In Δ AOC

∵ OA = OC

∴ Δ AOC is an isosceles triangle

→ Base angles of the isosceles triangle are equal

∵ ∠OAC and ∠OCA are the base angles of the triangle

∴ m∠OAC = m∠OCA

∵ m∠OAC = a°

∴ m∠OCA = a°

→ The sum of angles in any triangle is 180°

∵ a° + a° + m∠AOC = 180°

∵ m∠AOC = 54°

∴ a° + a° + 54 = 180°

→ Add the like terms

∴ 2a° + 54 = 180°

→ Subtract 54 from both sides

∴ 2a° = 126°

→ Divide both sides by 2

∵ m∠OAC = m∠OCA = 126 ÷ 2

∴ a° = 63

∴ The value of a is 63°

In ΔBOC

∵ OB = OC

∴ Δ BOC is an isosceles triangle

→ Base angles of the isosceles triangle are equal

∵ ∠OBC and ∠OCB are the base angles of the triangle

∴ m∠OBC = m∠OCB

∵ m∠OBC = b°

∴ m∠OCB = b°

∵ ∠AOC is an exterior angle of ΔBOC at the vertex O

→ The measure of the exterior angle equals the sum of the measure

    of the opposite interior angles to this vertex

∵ ∠OBC and ∠OCB are the opposite interior angle of ∠AOC

∴ m∠OBC + m∠OCB = m∠AOC

→ Substitute their measures

∵ b° + b° = 54°

→ Add the like terms

∴ 2b° = 54

→ Divide both sides by 2

∴ b° = 27

∴ The value of b is 27°

For this problem, we're finding the percent of 300. To do that we:

1. Multiply 300 by 15.

300 x 15 = 4500

2. Divide 4500 by 100. (% = 100)

4500 / 100 = 45

Therefore, the unit price is 45. But we're not done. We need to subtract 45 by 300.

300 - 45 = 255

Now, our answer is 255 and the unit price is 45.

drivers license do you like that song?

Step-by-step explanation

I got my driver's license last week

Just like we always talked about

'Cause you were so excited for me

To finally drive up to your house

But today I drove through the suburbs

Crying 'cause you weren't around

And you're probably with that blonde girl

Who always made me doubt

She's so much older than me

She's everything I'm insecure about

Yeah, today I drove through the suburbs

'Cause how could I ever love someone else?

And I know we weren't perfect but I've never felt this way for no one

And I just can't imagine how you could be so okay now that I'm gone

Guess you didn't mean what you wrote in that song about me

'Cause you said forever now I drive alone past your street

And all my friends are tired

Of hearing how much I miss you but

I kinda feel sorry for them

'Cause they'll never know you the way that I do

Yeah, today I drove through the suburbs

And pictured I was driving home to you

And I know we weren't perfect but I've never felt this way for no one

Oh, and I just can't imagine how you could be so okay now that I'm gone

I guess you didn't mean what you wrote in that song about me

'Cause you said forever now I drive alone past your street

Red lights

Stop signs

I still see your face

In the white cars

Front yards

Can't drive past the places

We used to

Go to

'Cause I still f- love you, babe

Sidewalks

We crossed

I still hear your voice

In the traffic

We're laughing

Over all the noise

God, I'm so blue

Know we're through

But I still f- love you, babe

I know we weren't perfect but I've never felt this way for no one

And I just can't imagine how you could be so okay now that I'm gone

Guess you didn't mean what you wrote in that song about me

'Cause you said forever now I drive alone past your street

Yeah, you said forever now I drive alone past your street

The length of each side of polygon is: 11 and 13 units.

polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).

AS, we know all the sides of polygons are equal

7x-3= 4x+3

3x= 6

x=2.

Hence, the side of the triangle are:

7x-3= 7*2-3

      = 11 units

4x+5=4*2+5

      = 13 units

Question:

What is the perimeter of the path, in miles?

Answer:

35 miles

Step-by-step explanation:

Given

Let the corners be ABCD

[tex]A = (-2,2)[/tex]

[tex]B = (1,2)[/tex]

[tex]C = (1,-2)[/tex]

[tex]D = (-2,-2)[/tex]

First, we calculate the perimeter of the corners in units.

This is done by calculating the distance between the corners.

Distance is calculated as:

[tex]D = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }[/tex]

For AB:

[tex](x_1,y_1) = (-2,2)[/tex]

[tex](x_2,y_2) = (1,2)[/tex]

[tex]D_1 = \sqrt{(1 - (-2))^2 +(2 - 2)^2 }[/tex]

[tex]D_1 = \sqrt{(1 +2)^2 +(0)^2 }[/tex]

[tex]D_1 = \sqrt{3^2}[/tex]

[tex]D_1 = 3[/tex]

For BC

[tex](x_1,y_1) = (1,2)[/tex]

[tex](x_2,y_2) = (1,-2)[/tex]

[tex]D_2 = \sqrt{(1 - 1)^2 +(-2 - 2)^2 }[/tex]

[tex]D_2 = \sqrt{(0)^2 +(-4)^2 }[/tex]

[tex]D_2 = \sqrt{16 }[/tex]

[tex]D_2 = 4[/tex]

For CD:

[tex](x_1,y_1) = (1,-2)[/tex]

[tex](x_2,y_2) = (-2,-2)[/tex]

[tex]D_3 = \sqrt{(-2 - 1)^2 +(-2 - (-2))^2 }[/tex]

[tex]D_3 = \sqrt{(-3)^2 +(-2 +2)^2 }[/tex]

[tex]D_3 = \sqrt{9 +0^2 }[/tex]

[tex]D_3 = \sqrt{9 }[/tex]

[tex]D_3 = 3[/tex]

For DA

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (-2,2)[/tex]

[tex]D_4 = \sqrt{(-2 - (-2))^2 +(2 - (-2))^2 }[/tex]

[tex]D_4 = \sqrt{(-2 +2)^2 +(2 +2))^2 }[/tex]

[tex]D_4 = \sqrt{0^2 +4^2 }[/tex]

[tex]D_4 = \sqrt{4^2 }[/tex]

[tex]D_4 = 4[/tex]

The perimeter P in units is:

[tex]P = D_1 + D_2 + D_3 + D_4[/tex]

[tex]P = 3+4+3+4[/tex]

[tex]P = 14[/tex]

Given that:

[tex]1\ units = 2.5\ miles[/tex]

Multiply both sides by 14

[tex]14 * 1\ units = 14 * 2.5\ miles[/tex]

[tex]14 \ units = 35\ miles[/tex]

Hence, the perimeter is 35 miles

Answer:

[tex]y-4=\frac{1}{2} (x+10)[/tex]

Step-by-step explanation:

Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] when the given point is [tex](x_1,y_1)[/tex] and the slope is [tex]m[/tex]

[tex]y-y_1=m(x-x_1)[/tex]

Plug in the point (-10,4)

[tex]y-4=m(x-(-10))[/tex]

Two negatives make a positive

[tex]y-4=m(x+10)[/tex]

Plug in the slope

[tex]y-4=\frac{1}{2} (x+10)[/tex]

Answer:

The image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

Step-by-step explanation:

Given

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

Rule to calculate the dilation by a scale factor 2/3 centered at the origin

P(x, y) → P'(2/3x, 2/3y)

Here, P'(2/3, 2/3y) is the image of P(x, y).

Thus,

A(2, 1) → A'(2/3(2), 2/3(1)) = A'(4/3, 2/3)

Therefore, the image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

Answer:

21 cm by 21 cm

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of any one side of the square.  Here,

441 cm² = x²

This actually has two roots:  {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.

The dimensions of the square are 21 cm by 21 cm.
