There are two identical bottles. One bottle contains 2 green balls and 1 red ball. The other contains 2 red balls. A bottle is selected at random and a single ball is drawn. What is the probability that the ball is red

Answers

Answer 1

Answer:

2/3

Step-by-step explanation:

P(b1) = probability of bottle 1 = 1/2

P(b2) = probability of bottle 2 = 1/2

Bottle 1 = 2 green, 1 red ; total = 3

P(red ball1) = 1/3

Bottle 2 : red balls = 2, total balls = 2

P(red ball2) = 2/2 = 1

P(red ball) = [p(b1) * p(redball1)] = 1/2 * 1/3 = 1/6

P(red ball) = [p(b2) * p(redball2)] = 1/2 * 1 = 1/2

1/6 + 1/2 = (1 + 3) / 6 = 4/6 = 2/3

For each side of each triangle, think of the side as the hypotenuse of a right triangle. Then use the Pythagorean theorem to find the length of the hypotenuse, which is the side of the triangle.

Left problem:

From point C to point A, go 2 left and 7 up.

[tex] AC = \sqrt{2^2 + 7^2} = 7.3 [/tex]

From point A to point B, go 5 right and 1 down.

[tex] AB = \sqrt{5^2 + 1^2} = 5.1 [/tex]

From point B to point C, go 6 down and 3 left.

[tex] BC = \sqrt{6^2 + 3^2} = 6.7 [/tex]

Perimeter = 7.3 + 5.1 + 6.7 = 19.1

Do the same for the other triangles.

Middle problem:

From point F to point D, go 2 left and 7 up.

[tex] FD = \sqrt{2^2 + 7^2} = 7.3 [/tex]

From point D to point E, go 7 right and 2 down.

[tex] DE = \sqrt{7^2 + 2^2} = 7.3 [/tex]

From point E to point F, go 5 down and 5 left.

[tex] EF = \sqrt{5^2 + 5^2} = 7.1 [/tex]

Perimeter = 7.3 + 7.3 + 7.1 = 21.7

Right problem:

From point L to point J, go 7 left and 1 up.

[tex] LJ = \sqrt{7^2 + 1^2} = 7.1 [/tex]

From point J to point K, go 4 up and 5 right.

[tex] JK = \sqrt{4^2 + 5^2} = 6.4 [/tex]

From point K to point L, go 2 right and 5 down.

[tex] KL = \sqrt{2^2 + 5^2} = 5.4 [/tex]

Perimeter = 7.1 + 6.4 + 5.4 = 18.9

flips a fair coin until a tail first appears, and if the number of tosses equals m, then Tom gets a payoff for 2 m pounds. Calculate the expected value of his payoff.

Answers

Answer: the expected value of Tom's payoff is

Step-by-step explanation:

Given the data in the question,

E[x] = mp                                        

where p = 1/2

Now Tom gets payoff pounds until a tail first appears = 2m pounds

so

E[x] = m × 1/2 × 2m

E[x] =

Therefore the expected value of Tom's payoff is

Step-by-step explanation:

The mixed numbers can be expressed as improper fractions in the usual way. The integer portion can be expressed as a multiple of the fraction denominator divided by itself.

Integers can be expressed as a ratio with 1 as the denominator.

1 2/5 = (1×5/5) +2/5 = (5+2)/5 = 7/5

0.3 = three tenths = 3/10

-3 1/4 = -(3×4/4 +1/4) = -(12+1)/4 = -13/4

-27 = -27/1

Theresa's computer at home has 1 terabyte of storage. How many more bits of storage does her computer have than the combined bits available on her family's phones, tablets, and cloud storage? Type your answer in scientific notation. Her family's phones, tablets and cloud storage equal 9.6 gigabytes.​

Answers

Answer:

Hope this helps! ( if not then sorry)

In scientific notation, the answer is [tex]7.9232 \times 10^{12}[/tex] bits.

To calculate the additional storage in bits that Theresa's computer has compared to her family's phones, tablets, and cloud storage, we first need to convert the 1 terabyte to bits and the 9.6 gigabytes to bits.

1 terabyte = 1,000,000,000,000 bytes

1 byte = 8 bits

So, 1 terabyte = 8 × 1,000,000,000,000 bits

= 8,000,000,000,000 bits

9.6 gigabytes = 9.6 × 1,000,000,000 bytes

= 9,600,000,000 bytes

9.6 gigabytes = 8 × 9,600,000,000 bits

= 76,800,000,000 bits

Now, we can calculate the difference in bits:

Difference = Theresa's computer storage - Family's phones, tablets, and cloud storage

Difference = 8,000,000,000,000 bits - 76,800,000,000 bits

Difference = 7,923,200,000,000 bits

Difference = [tex]7.9232 \times 10^{12}[/tex]  bits.

Thus, in scientific notation, the answer is [tex]7.9232 \times 10^{12}[/tex] bits.

[tex]\huge\bf\underline{Answer}[/tex]

Given :-

Total surface area of a cube = 1944cm²

To Find :-

Side of the cube

Formula :-

[tex]\boxed{\huge \sf{TSA = 6a²}}[/tex]

Where,

TSA = Total surface area of a cube

a = Side of a cube

Solution :-

Let the Side of a cube be 'x'

By substituting values according to the formula,

[tex]\sf{:⇒6(x) ^{2} } = 1944cm^{2} [/tex]

[tex]\sf{:⇒ {x}^{2} = \dfrac{1944}{6} }[/tex]
