Answer:

The probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Step-by-step explanation:

Step 1:

The probability that, in successive drawing of chips, the colors of the first four chips alternate, can occur in two ways: RED-WHITE-RED-WHITE (RWRW) or WHITE-RED-WHITE-RED (WRWR).

Step 2:

Given that an urn contains three white and four red chips and that each time we draw a chip, we look at its color. If it is red, we replace it along with two new red chips, and if it is white, we replace it along with three new white chips.

Probability of RWRW is given as follows:

Probabilty of the first being a red = 4/7

Probability of the next being a white = 3/9 = 1/3

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/14 = 3/7

Thus, probability of RWRW = 4/7 × 1/3 × 1/2 × 3/7 = 0.0408

Probability of WRWR is given as follows:

Probabilty of the first being a white = 3/7

Probability of the next being a white = 4/10 =2/5

Probability of the next being a red = 6/12 = 1/2

Probability of the next being a white = 6/15 = 2/5

Thus, probability of WRWR = 3/7 × 2/5 × 1/2 × 2/5 = 0.0343

Step 3:

Probability of RWRW or WRWR = 0.0408 + 0.0343 = 0.0751

Therefore, the probability that, in successive drawing of chips, the colors of the first four chips alternate = 0.0751

Answer:

x = -4

B is the answer

Step-by-step explanation:

To find the axis of symmetry, we will need to find the vertex of this function.

I have provided you with the steps to find the vertex.

After finding the vertex, pay attention to the x-value of the vertex because that is the axis of symmetry too. Hope this helps :)

Answer:

9

Step-by-step explanation:

Answer:

y = - x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 9) and (x₂, y₂ ) = (9, 0) ← 2 points on the line

m = [tex]\frac{0-9}{9-0}[/tex] = [tex]\frac{-9}{9}[/tex] = - 1

The line crosses the y- axis at (0, 9 ) ⇒ c = 9

y = - x + 9 ← equation of line

Answer:

20 cashiers

Step-by-step explanation:

There is 10 boxes. Each cashier is given 1/2 of one box.

10 multiplied by 2 (which is 20) gives you the amount of cashiers since each one is given one half and there is 20 one halfs in 10.

Answer:

V = 29.31 cm^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

V = 1/3 (3.14) (2)^2 (7)

V =29.30666

Rounding to the nearest hundredth

V = 29.31 cm^3

Answer:

Adrianna's bedroom has a perimeter of 14 m/s. The width is 3 meters. What is the length of her room?

The answer is 4 meter (s)

Step-by-step explanation:

Hope the picture helps

The length of her room is 4 meters.

The formula for the perimeter of a rectangle is (width + height) x 2.

Adrianna's bedroom has a perimeter of 14 meters.

The width is 3 meters.

Let, the length of her room be x.

The length of her room is;

[tex]\rm Perimeter \ of \ room =2 (Length +Width)\\\\14 =2(x + 3)\\\\14 = 14=2x+6\\\\2x=14-6\\\\2x=8\\\\x=\dfrac{8}{2}\\\\x=4[/tex]

Hence, the length of her room is 4 meters.

Answer:

   yes

Step-by-step explanation:

The triangles are given as right triangles. Hypotenuses QT and RS are given as congruent.

We also have XS ≅ TP. By the addition property of equality, this means ...

  XS +ST ≅ ST +TP

By the segment sum theorem, this means ...

  XT ≅ SP

XT and SP are the corresponding legs of the right triangles. So, we have corresponding hypotenuses and corresponding legs congruent. This lets us conclude ΔXQT ≅ ΔPRS by the HL theorem.

Answer:

Step-by-step explanation:

20% = 20/100 = 0.2

The amount you need to pay for a T shirt is

Cost = original amount(100% - 20%)

Original amount = 18

100% - 20% = 80%

80% = 80 / 100 = 0.8

What this means is that you will pay 80% of  the original cost.

Cost = 18*0.8

Cost = $14.40

Part B

Cost = 0.8 * x

Part C

Selling price = 0.8*Original Cost

Selling price = 18

18 = 0.8 * x

18/0.8 = x

x = 22.5

The original price was $22.50

Answer:

17 cm

Step-by-step explanation:

Rectangle perimeter: length*2 + width*2

Substitute width with "x".

Length is given as 15 cm

Perimeter is given as 64 cm

Plug in the values and solve for x.

64 = 2*15 + 2x

64 = 30+2x

2x = 34

x = 17

so width is 17 cm

Answer:

  more than 410

Answer:

1 / 7

Step-by-step explanation:

Given the distribution above :

P(grade B or higher) can be defined explicitly as :

P(Grade A) + P(Grade B)

P(grade A) = 2/35

P(Grade B) = 3 / 35

Hence,

P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7
