if two identical dice are rolled n successive times, how many sequences of outcomes contain all doubles (a pair of 1s, of 2s, etc.)?

Answers

Answer 1

1 sequence of outcomes that contains all doubles when two identical dice are rolled n successive times.

There are 6 possible doubles that can be rolled on a pair of dice (1-1, 2-2, 3-3, 4-4, 5-5, 6-6).

Let's consider the probability of rolling a double on a single roll:

The probability of rolling any specific double (such as 2-2) on a single roll is 1/6 × 1/6 = 1/36 since each die has a 1/6 chance of rolling the specific number needed for the double.

The probability of rolling any double on a single roll is the sum of the probabilities of rolling each specific double is 1/36 + 1/36 + 1/36 + 1/36 + 1/36 + 1/36 = 1/6.

Let's consider the probability of rolling all doubles on n successive rolls. Since each roll is independent the probability of rolling all doubles on a single roll is (1/6)² = 1/36.

The probability of rolling all doubles on n successive rolls is (1/36)ⁿ.

The number of sequences of outcomes that contain all doubles need to count the number of ways to arrange the doubles in the sequence.

There are n positions in the sequence, and we need to choose which positions will have doubles.

There are 6 ways to choose the position of the first double 5 ways to choose the position of the second double (since it can't be in the same position as the first) and so on.

The total number of sequences of outcomes that contain all doubles is:

6 × 5 × 4 × 3 × 2 × 1 = 6!

This assumes that each double is different.

Since the dice are identical need to divide by the number of ways to arrange the doubles is also 6!.

The final answer is:

6!/6! = 1

Sam owns a chain of fast food restaurants that operated 200 stores in 1999. If the rate of increase is 8% annually, how many stores does the restaurant operate in 2007?

Answers

Answer:

370 stores

Step-by-step explanation:

Given data

initial number of stores P= 200

r= 8%

t= 1999-2007=  8 years

Let us apply the compound interest expression to find the final amount of stores

A= P(1+r)^t

A= 200(1+0.08)^8

A= 200(1.08)^8

A= 200*1.85

A=370

Hence the number of stores in 2007 is 370 stores

Answer:

First one: 12 ft

Second one: 50ft^2

Step-by-step explanation:

Because both triangles are congruent, any value on one triangle is the same one on the other triangle so CBD= 12ft for the perimeter

Second one:

because both triangles are congruent like I stated above, both triangle are congruent.

But in this case we have to find the area of the whole rectangle.

What we do here is multiply 25 by 2

or

add 25+25

our answer is 50ft^2

divide 450 in the ratio 2 is to 3 is to 5​

Answers

Answer:

90 : 135 : 225

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 + 5 = 10 parts

Divide the number by 10 to find the value of one part of the ratio

450 ÷ 10 = 45 ← value of 1 part of the ratio, then

2 parts = 2 × 45 = 90

3 parts = 3 × 45 = 135

5 parts = 5 × 45 = 225

Then

450 in the ratio 2 : 3 : 5 is 90 : 135 : 225

Cheryl signs up for a savings account that guarantees an increase in her savings at a fixed rate of $15 per month. She plans to withdraw the money when it is more than twice the original amount of $200. Find the least number of complete months that Cheryl has to keep the money in the account for.

Answers

Answer: 14 months.

Step-by-step explanation:

Given: Original amount = $ 200

Fixed rate of growth = $15 per month

Let x be the number of months that Cheryl has to keep the money in the account for.

Then, [tex]200+15x=2(200)[/tex]

[tex]\Rightarrow\ 200+15x>400\\\\\Rightarrow\ 15x >400-200\\\\\Rightarrow\ 15x>200\\\\\Rightarrow x>\dfrac{200}{15}\\\\\Rightarrow x>13.333333\\\\\Rightarrow\ x=14[/tex]

Hence, it will take 14 months .

At what times between 8.00 am and 2.30p.m do the bells both rring

Answers

Find multiples of 30 and 40:

30: 30, 60, 90, 120, 150

40: 40, 80, 120, 160

The least common multiple is 120, so every 120 minutes they willl both ring.

1 hour = 60 minutes:

120/60 = 2 hours.

The bells ring together every 2 hours.

8 + 2  = 10 am

10 +  = 12pm

12 + 2 = 2 pm

The bells will ring together at am, 12 pm and 2 pm.

Answer:

Solution :-

At first common multiple of 30 an 40

[tex] \sf \to \: 30 = 30,60,90,120[/tex]

[tex] \sf \to \: 40 = 40,80,120[/tex]

Common Multiple = 120

Time taken = 120/60 = 2 hrs

Now,

8.00 + 2 = 10.00 am

10.00 + 2 = 12.00 noon

12.00 + 2 = 2.00 pm
